As Exhibit 11 illustrates, the Planning Commission was asked to review a modification to the Westlake PUD •1 master plan and a Class II variance to LODS 18.020(3) in order to allow a limited access (right • in/right out only) on Kruse Way. Those requests were denied by the Planning Commission. The applicant requested that the Board's hearing be continued to February 19, 1992, so that they can . ; submit revised information and so that citizens are provided an adequate opportunity to review the information. The applicant has submitted the following exhibits for the Board's review: Exhibit 51 Letter by Steven K. Routon (OTAK),dated.lanuary 24, 1992 E. • Exhibit 52 Letter by Daniel A. Seeman (l ittelson &Associates, Inc.), dated January 31, 1992 Exhibit 53 Revised Site Plan 4,y Exhibit 54 Revised Sanitary Sewer&Water Plan Exhibit 55 Revised Storm Drainage &Grading Plt,:n Exhibit 56 Revised Landscape Plan (for Kruse Wa.!Subarea) , Exhibit 57 Revised Site Lighting Plan Exhibit 58 PUD 3-80(Mod. 11 •91)/VAR 15-91-931 —Findings, Conclusions &Order Based on an analysis of the information above, staff makes the following findings: Wetlands: As Exhibits 53 and 56 illustrate, the elimination of the Kruse Way access will reduce the project impact on the existing wetlands on the site. While the impact area will be reduced from .32 acres to ,24 acres, the proposed mitigation area will remain the same at .34 acres, Exhibit 51. • For a detailed staff analysis and discussion of the wetland issue please see the January 10, 1992 staff report,pages 8 and 9. 00, f ,4 No \" \11't11I1` • I'u•d I)11:u Iu, 40 • I,11:,'t 1•,N,,,0 I lt, ',,I,,Il1 t i I'I,1IlI II,m.11161 4.1, 1 ,01,1,1,i 1,"111 • 1i111:.�1111; I)1t-1 I1 1 +I �I Y,ti�Ilv,ll Y ( ,y l +- ll ilhi+Yl,yl+tl t y ,ti 44 + + , � � , V. » 1 nM , • • . ' Transit: Exhibit 53 does not illustrate the proposed pathway from Parkview Drive to Kruse Way (as was shown on the original site plan,Exhibit 11). Kruse Way is a public transit corridor, with transit facilities at its intersections with Carman Drive and Westlake Drive. Therefore, to comply with •, the requirements of LODS 6.020(1) and (2), the above pathway should be reinstated in order to provide adequate pedestrian access to adjacent transit facilities. The pathway location should be AD : : designed so as to minimize any conflict with the wetlands along Kruse Way, The pathway 'u' f. should provide a pedestrian connection through the site to connect Parkview Drive and Kruse - Way. This will further implement Plan policies which require safe convenient access enabling residents to travel safely on foot or bicycle throughout the community,Transportation Policies, General policy VI. i • Utilities As Exhibit 11 illustrates, the project was originally designed with three access point, two on • Parkview Drive and one on Kruse Way (a limited right—in/right—out driveway). On January 13, 1992,the Planning Commission denied the Kruse Way access alternative,Exhibit 58. The applicant has since revised the site plan and other supporting evidence, including the traffic report. The supplemental traffic report(Exhibit 52) indicates that even without the Kruse Way access,the project will continue to function within acceptable level of service during the morning and evening peak hours, with minimal traffic related impacts to the adjacent streets and nearby intersections. These findings are consistent with earlier findings in Exhibits 36. The traffic reports (Exhibits 36 and 52) also identify several improvements necessary along ;`. Kruse Way at the intersections of Kruse Way and Carman Drive and Westlake Drive. These improvements would be needed to accommodate the project traffic for the year 2000. While the , evidence suggests that the improvements ma)' not be necessary at this time, staff finds that the F '.I, applicant's participation is necessary to adequately address these needs. Therefore, the applicant will be required to sign a nonremonstrance agreement for future improvements of the above 0 ,-.. ,. ,,,.. intersections. CO.NCLUSION Based upon the information submitted by the applicant and staff findings presented in this report, staff concludes that DR 15-91/PD 6-91 can be made to comply with all applicable criteria by the .� '. application of certain conditions.

We have enclosed all of the revised plans for Westlake II. The only change made was the deletion of the access onto Kruse Way from the project site. alp; Due to these changes, the wetlands "area of impact" and "impact fill" totals have decreased. Area "C" as described on sheet W-1, will no longer be impacted, This reduces the total area of impact to .24 acres and reduces the impact fill to 770 :.3 cubic yards. The mitigation area will remain the same, .34 acres, wigich results in A a surplus mitigation area of 4,356 square feet.

Since that original analysis was submitted, the alternative access that wasp" being proposed (onto Kruse Way) has been denied. This letter summarizes the findings and , recommendations of the analysis for the development, assuming that exclusive access is provided via two driveways on Parkway Drive. Based on the results of the analysis,the proposed site can be developed as planned with minimal traffic- s related impacts to the adjacent street system and nearby intersections. The significant findings and ( .• recommendations are as follows: "` The keysignalized and unsignalizedv- • _'' gn intersections within the study area arc currently operating at an acceptable LOS during weekday morning and evening peak hour conditions. a; • Upon completion of the development,the site driveways and key off-site intersections will continue to operate within acceptable level of service limits during the morning and evening peak hours. • The traffic analysis conducted for this project is consistent with the the Buttke report, prepared for the Westlake PUD in 1979 and amended in the early eighties. The current traffic patterns in the Westlake development arc consistent with the previous traffic *•' assumptions and conclusions containced in the previous traffic reports. The analysis •• indicates that this development will not adversely impact the surrounding street system. , , • The Westlake Drive/Kruse Way intersection will require the addition of a right-turn lane on the westbound approach to the intersection to be able to accomodate projected year 2000 traffic volumes, 1.. • Both the northbound and southbound approaches to the Carman Drive/Kruse Way t • d; intersection wit need to be widened and improved to allow for the provision of separate ,, e left-turn, through and right-turn lanes to be able to accomodate projected year 2000 traffic •. volumes. 4x EXHIBIT =, tl' A G a DANAI/s'VG�ciI e T6. • • I 4 i `"•� a. t y �yb 1 ♦ Mr. Nawzad Othman January31, 19 9 • Page 2 1'. • The improvements identified above will not be warranted upon completion of this development, but rather will be necessa ry ary at some time in the future as traffic volumes within the study area begin to approach the year 2000 forecast levels. It is important to • note that these improvements will not be warranted upon po completion of this development, but rather will be necessary at some time in the future as traffic volumes within the study area begin to approach the levels identified in the year 2000 forecasts. I trust that this letter addresses the concerns that you have regarding the revised project.

I live in the Park at Westlake (5010 SW Greensborough Ct.) and back up to the wetland n .. mitigation area pond. I was very careful to purchase a house that did not back up to a public area or apartments. It was my understanding, as in the �• pt n . g, the original plan, that I would have houses behind mine. Instead a large wetland mitigation pond was approved/put behind my house. As a result, the back of my house now looks through this open space into Parkview Drive and the proposed apartment development. " I am opposed to this project. The main reason relates to traffic as well as the noise and • safety issues associated with it. The developer went before the Planning Commission to ask for a modification of the Westlake Planned Unit Development master plan in order to ;, «� introduce a direct access point on Kruse Way. Without this modification, the proposed project is entirely unacceptable to me. If there is any way that the Development Review •. Board can send this back to the Planning Commission or to City Council, I think that it a' should. The residents in the Westlake area have expressed concern over the traffic problems for years. As you know, a large track of houses on small lots as well as a commercial development have already been approved on Parkview. I feel that the Planning Commissions K" findings were not sound. A) They used the applicants traffic report which may or may not , *` really reflect the amount of traffic that will be on Parkview when all projects are completed. �,. B) They claimed that a Kruse Way access would be injurious to the public since it would cut across the bike path. This bike path is interupted by several other streets at several other ,, points. One more street stop would not make it suddenly dangerous. C) The Planning Commission felt that a Kruse way access would have a negative visual aesthetic impact on • G • the recreational use of the existing pathway. I feel that the noise and safety problems on • j• Parkview are much more important to the neighborhood than how one very small portion of a ` bikepath looks. Since Parkview Drive has been opened through to Carmen, there has been a great increase in noise at all hours of the day and night. I feel that there will be too much traffic and noise on Parkway Drive with all the other ' approved projects for an apartment complex to be approved in addition and don't support this project. However, if it is approved I feel that the Kruse Way access must be there. It is very unfortunate that the Planning Commission would rule against a request of such importance r that both the residents and developer agreed upon. 4 fec •` ' b.

My house backs up to the wetland mitigation pond north of Parkview (see enclosed pictures). I am very unhappy with the size _ and quantity of the plants (and seriously hope that more work will take place on it, including g�' '.� more mature plantings, in the near future). I feel this development should be required to have more mature plantings on both Parkview and in its wetlands mitigation area. Also, I would like to see some evergreens put in front of the apartments on Parkview. a 2) I attended a pre-hearing meeting some months back with the developer. I greatly appreciate the fact that they did set some of the proposed apartment buildings back farther off 4 Parkview after this discussion, The Dominion plan had a fence along Parkview. Since this developer eliminated that fence, I would still like to see Building A on Parkview on the NW corner of the development set back a little farther from the street. i I i Thank you for taking the time to consider my concerns. • • • 1 a Sincerely, Cynthia Johnson •• 7 y ' 7• • Attachment' Wetland mitigation pond photos _, -•a t:. _ • `fib,I. • •" 4� 4 I l r • • • , .„ ,, ,,. .', ''. , *!,'• •' , -•;'''.• ,. •, .

Y ,y / City Cou 1 f City ke Oswego -F- 13c 6 1.99E 380 Street La Oswego, Oregon 97034 •fl Dear City Council Members: . 4 It is our understanding that a 352 apartment complex is being considered off Kruse Way, near the church that is being built on the corner of Kruse and Carmen. 8ue to the high traffic density that now occurs, we do not believe it should be allowed. Please consider the following: • `. ' 1.)Traffic density on Quarry, the road Westlake residents primarily use to reach Boons Ferry, is nearly bumper to bumper at rush hours. Koet drivers travel this street " •. at 35-40 miles per hour. With this a residential area with many children, and with . ,• Waluga Park, do with want to take the chance of a serious injury before we do something? • 2.)Leaving the Heritage Hills development onto Quarry is risky, with the speed people are traveling, particularly near the blind turn on Quarry. ,. 3.)This turn should have a 20 mile per hour restriction, with a warning sign, or speed bumps. 4.)Police patrols should be increased on Quarry, as neither the speed limits, or new stop signs near the park, are rarely observed. We know demands are great on our force, and we understand this can only be done as time permits. , 5.)Westlake desperately needs their own shopping area to reduce this traffic. b.)Since the proposed mini-mall" in Westlake will not help this reecific apartment complex, I' ' ,, ' the complex should not be approved, or should not be approved 'n its present large size. If any complex is approved, it shold be required to have shops nearby, or at least a convenience store, on the apartment site. 7.)The intersection of Kruse Way and Carmen Drive should have a left turn only signal to reduce the dangers there. M 1 • 8.)Th idea deidofed This wil no l going east on Boones Ferry to turn onto Quarry should not simply force people to use the very narrow Douglas Way access, or the ; y congested Mercantile Village area. '< We would appreciate it if you would respond to our concerns.

FINDINGS • y .i A. EXLSting COO] ltion: 1. The site is 20,82 acres in size and is vacant, with primary vegetation consisting 1 of field grasses and one apple tree over 8" in diameter, It slopes gently from DR 15-91/PD 6-91 p , , I. Page 2 of 15 C- N il- 19 north to south at approximately 4% grade,Exhibit 10. There are several small f, wetland areas on the site,including a narrow,man—made ditch constructed for prior agricultural uses along the west pn,perty line,Exhibits 9, 32-34 and 49. ' 2. The surrounding land uses are as follows: —North: Single—family Phase 4(The Meadows —Northwest Wetland Tract "I"in the Phase 4,above —South: � P�edestrian/bicycle path along Kruse Way,Vacant Commercial . Land(across Kruse Way—Remaining Kruse Family Fann) , —East: Lake Baptist Church (currently under construction) —West: Westlake Meadows Apartments 3. All public utilities and services,including streets water, sanit ary sewer and storm sewer are currently available to serve the site. ,, B. > c! �n l: ?.., •` 4� 1. The site is designated as Multi—family Phase 3 on the Westlake Planned Unit Development(PUD) master plan,Exhibit 3. The PUD was approved by the City ;', Y Council on March 3, 1981. The site is regulated by the Westlake Final Development Plan and Program which was adopted by Ordinance 1783. The Final Plan and Prograin lists the uses allowed on the site and establishes site development criteria as follows: —Density: 347-391 units (Exhibit 3) —Height: 45' —Setbacks: Front yard 10'; side yards to be a distance equal one half the height of the principal structure Lot Coverage: Maximum 50% —Parking: 1.5 spaces per unit • 2. Westlake—Phase I preliminary plat was approved in April 1981. That approval ,. +` •� later was modified into three sub—phases, 1—A, 1—B and 1—C. Phase 1—B was later modified into Phase 1—B and 1—B2. 3. A one year time extension was granted to the Phase 1 plat in May 1982. 4. On January 23, 1984, the Planning Commission approved ODPS 2-83 which ' involved a one year time extension to finalize the final plat for Phase 1—A, an extension of filing time to 1987 for the remainder of Phase 1 and an extension of ,. ' scheduling for the remaining PUD area to 1990. 5. On November 14, 1984, the Planning Commission approved several text il° modifications to the final development plan and program for Westlake. That f • approval also involved changes in schedules, allowed density transfer within the "< PUD, and modified the phasing locations. Some of these actions occurred to allow location of the LDS Temple north of Centerpointe+ 6. On April 8, 1985, the Planning Commission approved further modifications to the final development plan and program. These modifications were to allow flexibility in lot area, dimensions and setbacks and to allow greater lot coverage = in the remaining single family phases (i.e.,excluding Phase 1). • r „4 r.r • DR 15-91/PD 6-91 Page 3 of 15 7. On October 6, 1989,the Development Review Board approved a minor land partition to divide Tax Lot 100(of Tax Map 2 lE 6) in order to create the subject property. 8. On January 3, 1990,the Development Review Board approved a 360-unit apartment project on the site. That decision was later appealed to the City Council. On September 5, 1990, the Council decided to remand the application to the Development Review Board for further analysis of the traffic related issues. No further action was taken on that application. 9. On January 13, 1992,the Planning Commission will have held a hearing to .` review a request to modify the Westlake PUD master plan and a Class II variance to DADS 18,020(3)in order to allow a limited access (right in/right out only)on Kruse Way, [PUD 3-80(m�,od. 11-91)/VAR 15-91]. "+ ,• Any approval of DR 15-91/PD 6-91 will be contingent upon the Planning Commission's approval of[PUD 3-80(mod. 11-91)/VAR 15-91]. • 10. The applierxit has held several neighborhood meetings with neighbors who live within 300' of the site and the Westlake Neighborhood Association. The '' minutes of those meetings are attached as Exhibits 44-47. C. Proposal: The applicant is requesting approval of a 352-unit multi-family housing project, consisting of four building types in 29 buildings (all 2 story), Exhibit 11. The project will include a mix of 1-bedroom/1-bathroom, 1-bedroom/1-bathroom with den, 1- bedraom/1--bathroom with loft, 2-bedroom/2-bathroom, and 3-bedroom/2-bathroom A. units. Parking will include carports. A community building with an outdoor pool • will be included. D. Compliance with Applicable Regulations: .. • As per LOC 49.615,the Development Review Board must consider the following criteria when evaluating quasi-judicial requests: • 1. The burden of proof,in all cases, is upon the applicant seeking approval. • • The applicant has submitted the information Pp required by LOC 49.31 S (1)-(12). ,:. These documents are as exhibits which accompany this report. 2. For any application to be Approved,it shall first be established that the • proposal conforms to : a. The City's Comprehensive Plan,and, • Applicable policy groups are listed on page 1 of this report. The applicant's narrative (Exhibit 30)provides a thorough analysis of these policies. • -Urban Service Boundary Policies: These policies require the City to manage and phase urban growth within the Urban Service Boundary with a logical planned extension of basic services. Specific Policy 5 for General Policy III, states that new development shall be serviced by an "urban level" of services, including schools, This policy also states that these services are to DR 15-91/PD 6-91 Page 4 of 15 • ;k be available or committed prior to approval of development. Exhibit 49 (the City , Council memora:idum of September 18, 1990) demonstrates that the current level of ; •=:• ;, school planningand coordination between the City and School District satisfythis ;. policy. The passage of the 17 million dollar school levy on November 7, 1989, and e construction of additional school facilities further satisfy this policy. � -Impact Management Policies: These policies require protection of natural resources from development, • comprehensive review of development proposals, and payment of an equitable share _ ` of the costs of public improvements. The policies require assurances that distinctive t areas will be preserved,soils will be protected from erosion, tines will be protected k from removal,streams will be preserved and that density will be limited to achieve r,' these results. Compliance with the a2 dlicable Development Standards reviewed below will assure conformance to th�:se Plan policies. Conditions of approval will be imposed when necessary to assure compliance. N -Wildlife Management Policies: �.; ., ., These policies require protection of upland habitat in the form of preserved open space,natural vegetation or foliage slopes. The related Development standards are reviewed in this report following an analysis of the applicable Plan policies. • " • -Weak Foundation Soils Policies: "" These policies are intended to protect development from damage caused by weak foundation soils. The entire site is identified on page 43 of the Comprehensive Plan fi as having a potential for moderate to severe limitations due to weak foundation soils. • The applicant has submitted a preliminary subsurface investigation report(Exhibit ' 39)which concludes that the site is stumble for the proposed developreent. It should • ' be noted that this study was originally performed for the earlier 360-unit apartment ' project on this site. The report also recommends that a final foundation investigation be performed in order to develop final recommendations for actual site preparation and development. • -Wetland Policies: 1:J These policies are intended to preserve wetlands in order to safeguard the ` groundwater recharge system,maintain water qualityand provide wildlife habitat. " These policies are implemented by the Wetland Standard addressed below, -Stream Corridor Policies: Y• These policies are intended to preserve natural resources and maintain water quality. w' These policies are implemented by the Stream Corridors Standard addressed below. -Social Resources Policies: These policies require protection of features valuable to community identity and y preservation of the natural and aesthetic qualities which are the pride of residents. These policies also encourage citizen participation in the development review °A process. As Exhibits 44-47 ilustrate, the applicants have held four meetings with _ ` representatives of the Westlake Neighborhood Association and the neighbors. Other policies are implemented through application of specific development standards such as the Wetlands Standard. Compliance to the applicable Development Standards , reviewed below will assure conformance to this Plan policy, ,: DR 15-91/PD 6-91 Page 5of 15 • r + 1 . ,., t n e - , I. ,.. . 4 ,4 1• ` .1 Y 1 -Residential Density&Site Design Policies: • These policies require that densitybe appropriately related to site conditions. They also provide for preservation of open space and natural features,efficient streets and ' circulation system,safe pedestrian and bicycle circulation, buffering from adjacent ' uses and streets,and building placement. As discussed on page 3 of this report, the original PUD approval has already assigned a density ranged of 347-391 units to this `.„., site. 44!ry -Transportation Policies: These policies require that streets be improved as planned when demand requires, They a'so require that a developer be required to dedicate additional right-of-way as necess ary to provide for widening. The applicants have adequately addnssed these Plan policies in Exhibit 15. b. The applicable statutory and Code rer;aria.ments and regulations 1,. including, ', • City ofLake Oswego Sign Ordinance: Exhibit 11 illustrates the location of proposed en and Kruse Way; however,no 'monuments on Parkview Drive graphics or color specifications have been provided by the applicant. o assure compliance with the provisions of this ordinance, `y applicant will be the • required to apply for a sign permit application to the satisfaction of ' °1 :M staff. .City of Lake Oswego Zoning Ordinance: `[ • a.

City ofLake Oswego Tree Cutting Ordinance: '' The applicant has demonstrated compliance with this standard in Exhibits 9, 11 and 30. Any tree removal as part id the proposed grading and utility construction will 4 require a tree cutting permit. As Exhibits 25 and 26 illustrate, the applicant will provide substantial landscaping in the project. c. City of Lake Oswego Development Standards; The site does not contain any Historic Resources or Floodplain; therefore, these standards are not applicable. • The applicant has provided substantial evidence to demonstrate compliance with the g r applicable standards in Exhibits 9--43 and 48. This report will address those standards which require additional discussion or where modifications to the • ' applicant's proposals axe recommended. Building Design—(2.()45--2.040) ' , ' The applicant has provided a narrative (exhibit 30) and graphic material, including a color board(Exhibits 11-20 and 48) adequately addressing the requireents of the Building Design Standard. These materials address the concerns originally expressed 7,` r ., by staff regarding the need to illustrate how the design of the proposed buildings relate to adjacent structures of good design and how they relate to each other, how " s t accessory structures are complementary to the proposed buildings, and the orientation '' ,4;. and clustering of buildings. In order to address staff concerns, the applicant has •,' .y • slightly reduced the number of units from 360 to 352,eliminated 3 buildings and .. . r ',' increased setbacks. , . i . DR 15-91/PD 6-91 • ' " Page 7 of 15 • • f Stream Corridors-(3.005--3.040) • The site contains one stream corridor. This is shown on the wetland impact plan (Exhibit 21)as a drainage ditch form Parkview Drive to Kruse Way,parallel to the westerly property line.The applicant is ; PP � proposing to move the stream to the west and integrate it into the new wetland mitigation and buffer zone area shown on Exhibit 22. The proposed wetland mitigation and buffer zone area varies in width from 50' to 120' and extends from Parkview Drive to the existin detention corner of the site. g pond at the southwest The proposed realignment of the stream is an allowed use in LADS 3.020(4)(b), (c), < and dd . The u'' ` ( ) permitted uses include minor realignment of streams,drainage improvements and open Pro pe space. As Exhibit 21 24 illustrate,the wildlife habitat and drainage values of the stream corridor are being protected and enhanced by the proposed wetland mitigation plan and stream realignment. A stream corridor of 50'- 60leastt 255' on eitherside of the streamwill be provided to insure compliance �reloca eed�have a buffer zone of at • g )• • As Exhibits 11,22 and 24 illustrate;in three areas the buildings touch the stream corridor and wetland buffer edge. The use and maintenance of these buildings may detrimentally affect the stream corridor and wetland buffer a ea next to the buildings. There should be special maintenance restrictions applicable to any work done within the wetland mitigation area. Af .G i x f{ Based upon the above analysis,staff recommends that the applicant provides the following: -A wetland and stream corridor conservation easements over the proposed wetland ' mitigation and buffer areas. The legal description of this easement should follow the proposed fence line and building footprint line around this area, down to the log : ; weir above the existingdetention _, pond,as shown on Exhibit 24. -Special maintenance restrictions in the easement and in the covenants for the development,regarding maintenance of the building adjacent to the wetland mitigation areas. Wetlands-(4.005-4.040) The existing wetlands on the site have been identified and delineated in Exhibits 9, 30 r' and 32-34. There are.56 acres of wetland on the site. Based upon an analysis of the functions performed by these wetlands, none of these areas has been identified as • essential wetlands,Exhibit 49. The applicant is ` =rFPproposing to fill approximately .32 acres of these wetlands. The �e proposed mitigation of this plea is shown on Exhibits 22 and 24, and is addressed in a i letter from John Lee dated December 24, 1991 (Exhibit 35). The applicant has ` already filed appropriate applications with the Division of State Lands and Army , Corps of Engineers (Exhibit 43). Approvals from these agencies must be obtained '; prior to approval of the final construction plans. After evaluating the mitigation plans and accompanying narrative (Exhibits 24 and •`' 25),staff also finds that the designation of buffer areas is confusing, because the actual wetlands being created extend into the buffer area, but arc being considered as wetland buffer zone. Staff finds that it would be clearer to call the entire area a ` "wetland and stream corridor conservation area" and show the actual wetland i DR 15-91/PD 6-91 Page 8 of 15 • th boundary being created. For staff recommended conditions,please see conditions " under stream corridors,above. • Street Lights--(5.005-5.040) `_ n k rr • .;; There are existing street lights along both Parkway Drive and Kruse Way. Exhibits 29,30 and 42 adequately address the requirements of this standard. Transit-(6.005-6.040) ♦ Kruse Way is a public transit corridor. The existing pathways on Parkview Drive, Kruse Way and Westlake Drive,and the future pathway on Carman Drive will r `, provide adequate pedestrian access to the existing transit facilities at the intersections of Kruse Way with Westlake Drive and Carman Drive,in compliance with LODS 6.020(1)and(2),Exhibits 2,5 and 11. .' Parking and Loading-(7.005-7.40) • As Exhibits 11 and 30 illustrate,the proposed site plan provides for 720 parking spaces. This total exceeds the requirements of this standard at 620 spaces,and the • Westlake Final Development Plan and Program requirements at 528 spaces. Of 720 parking spaces proposed,352 spaces will be carports,and a total of 49% will be Y. designed as compact spaces. Exhibit 11 also illustrates the proposed width and depth of parking stalls and the width of the cross aisles in conformance with this standard. Park and Open Space--(8.005 8.040) As part of the Westlake PUD approval,46 acres of open space land was required to be allocated in the development. Of that total,41 acres have already been provided by Westlake Phase 1 and Centerpointe Development,as shown on Exhibit 4. The ,w ' • remaining balance of 5 acres is required to be distributed between Lot 8 of Centerpointe plat(Multi-family Phase 1), Multi-family Phase 3 (the site), and Single Family Phase 2 [condition 2 e .• ► O(6)of ODPS 2-84-207]• ., The 1.3 acres wetland mitigation asrea,includinz wetland buffer area and landscaped ' . detention pond,is proposed to satisfy the required open space on the site (Multi- " family Phase 3),Exhibit 31. The remainder balance of 3.7 acres of open space will ~ r he provided by the remaining phases as described above. .', Landscaping,Screening and Buffering-(9.005-9.040) ' • This standard requires that the development provide 20% of net buildable area in y landscaping in addition to the park and open space requirements. As Exhibit 11 ' illustrates, the development provides 10.17 acres of the site in landscaping, exceeding the 3.77 acres required by this standard. Exhibits 25,26 and 30 illustrate the typical °type, size and location of proposed street trees (Autumn Applause Ash). These plans also show the overall landscape design of the project. The proposed conifer trees are shown to be 6' in height. The proposed size should range from 6' to 8',especially along Kruse Way to provide better .• r buffering. Staff finds that additional parking lot planters are necessary to break up long rows of cars. The wetland mitigation plan is shown on Exhibit 23, Prior to the issuance of any y building permits, the applicant will',be required to submit a final r landscape plan showing the following information: ,' " DR 15-91/PD 6-91 f " Page 9 of 15 • x w t 1 r S -, r.+ e. • — Quantity and size of proposed planting materials,including the wetland planting' t — Additional parking lot planters • — An irrigation plan '.S r Fences—(10.005-10.040) the applicant pp ' proposes two types of fence in the development, a grade leveJ patio + fence not exceeding 6'in height,and a 4'fence around the wetland mitigation area (as required by the Department of Fish and Wildlife,and Division of States Land),in ti e...s, ,. compliance with LODS 10.020(1). Drainage for Major Development—(11.0'0S-11.040) et N,t • a, As Exhibits 6,27,30,40,and 41 illustrate,the site will be served by an existing regional storm detention facility located at the southwest corner of the property. This facility was constructed by the Single—family Pitase 4. / After reviewing the above information,staff makes the following observations: —Detention: The proposed "Dry Filter Pond Forbay"is located inside the existing detention pond and would reduce its storage volume. To provide this volume L ` u elsewhere may require using steeper slopes which would be difficult to maintain. The applicant has not shown how and where this detention volume can be provided. : ::' In addition,there are other options available to using the forbay. (See water quality y '{ below) —Water Quality: Exhibit 41 addresses water quality requirements and the phosphorus removal design formula. The proposed drainage plan (Exhibit 27) a „ appears to address the City's and DEQ's water quality requirements with two r exceptions pertaining to the proposed"Dry Filter Pond Forbay": 0 . . . • The forbay reduces the required detention capacity as discussed above. • The purpose of the forbay is to catch sediments and floating material from the KP::1 storm drain system. The forbay would require routine maintenance and cleaning, Maintenance of this facility would be difficult due to lack of adequate , ', access to maintenance vehicles and the landscaping in the detention pond area. ' A preferred option to the forbay would be to provide pollution control manholes or vaults in the storm drain system in on—site driveways. Theses manholes will be readily accessible to the maintenance vehicles. t >. r —Easements: Drainage easements will be required over the wetland and scream corridor areas, over the storm water detention area, and over any pollution control j,` manholes or vaults. . • Weak Foundation Soils—(13.005-13.040) 1`. The applicant has provided a preliminary subsurface investigation report(Exhibit 39) which addresses the feasibility of the development on the site using standard spread ;; footing foundation design. The report also recommends that a final evaluation be .. . , performed in order to develop final recommendations for actual site preparation and development. The applicant will be required to submit a final soils report and, ' incorporate all future recommendations in the project design prior to approval of final 0 ' ,. construction plans. • ,•',' 1V . ... •I ' .,,:*:, 44- • DR 15-91/PD 6-9 1 u Page 10 of 15 u '••' J - e r .,.i •�, .a a wt f wi a .(4,,. `. • !

Since Parkview is a new street, no road cutting will be allowed. The applicant must relocate the proposed Parkview connection (water) and provide calculations for minimum fire flow requirements prior to approval of the final construction plans. t y Sanitary Sewer. As illustrated on Exhibit 28, the proposed layout can adequately serve the site. tv 1 Y Streets: Based on a ruling by the Land Use Board of Appeals (LUBA) in Hoffman v. • City of Lake Oswego,staff find that the traffic related issues were resolved by the City Council in 1981 as part of the original Westlake PUD approval. The applicant r . . has submitted a new traffic reports (Exhibits 36, 37 and 38) to ascertain the development's impact on surrounding street system. These reports conclude that the site can be developed as planned with minimal traffic-related impacts to the adjacent streets and nearby intersections. The specific findings and conclusions are list on , pages 1 and 2 of Exhibit 36. The City traffic Engineer has reviewed the above information and supports their general findings and recommendations,including the need for a right-turn lane on the westbound approach at the intersection of Kruse Way and Westlake Drive,Exhibit • , :` ' 50. While the evidence suggests that the above improvement may not be necessary at this time,staff finds that the applicant's participation is necessaryto address this need. The applicant will be resta anuately required to sign a nonremonstrance agreement for future improvement of the above intersection. . The specific intersection design concerns affecting the limited access driveway on `" Kruse Way,including deceleration taper/lane and radius design,have all been x incorporated into the site plan,Exhibit 11, a o Staff review of the utility plans only verified the capacity of public facilities and services to serve the development. Final determinations regarding the exact location •.• :` .=- and size of these services will be made prior to approval of the final construction plans. All off-site easements must be obtained and provided to the City prior to approval of the final construction plans; All on-site easements over new public utilities must be provided to the City prior to issuance of any occupancy permits. Hillside Protection and Erosion Control-(16.005--16.040) e.' The site is relatively flat, sloping at approximately 4% towards Kruse Way, No ` N erosion control plan has been submitted by the applicant. A detailed erosion control plan should be submitted with the final construction plans.

WEST%•AKE U APARTMENTS i REQUEST FOR DEVELOPMENT REVIEW APPROVAL APPLICATION NARRATIVE I. APPLICANT'S REQUES This request is for approval of the Westlake II Apartments, The subject property is tax lot 100 , Map 2 1E 6, previously referred to as the "Dominion parcel". The .� _• Westlake II project will include 352 dwelling units. A large variety of units have been planned and are tabulated in the site data on Exhibit Al, Y l, • These include: - small 1 bedroom/1 bath units • - larger 1 bedroom/1 bath units - 1 bedroom/1 bath with den - 1 bedroom/lott - 2 different 2 bedroom/2 bath units • • 3 bedroom/2 bath units. The units are combined into 4 building types, all 2 stories high, Parking is provided at a ratio of 2 spaceshinits. Half of these spares will be carports, No garages will be provided, A recreation center and leasing office have been combined to form a 4,490 square foot community building. Services include a living room/lounge, media room, kitchen, restrooms, sun tanning table and exercise room. A separate bathhouse with showers, lockers and a sauna is adjacent to a proposed fenced outdoor swimming . ," pool. The site has .56 acres of jurisdictional wetlands, with .32 acres impacted by ' • construction. Mitigation will be in the form of creation in the amount of.34 acres. These wetlands will be discussed later in Sections ffi and IV. U. BACKGROUND INFORMATION K The subjectproperty � �' was previously approved by the city for a 352-unit apartment project known as Pointe South (DR 10-89/PD 14-89), The project was appealed to • k the City Council on the issue of traffic capacity, Ci ty ty The City Council remanded the t project with the direction that a traffic studybe reared, ' prepared, Subsequent to that decision by the City Council, the Oregon Land Use Board of Appeals ruled in the "Hoffman" case that a traffic study was not required, This application includes a traffic study so that traffic impacts are fully documented, That report concludes • that the street system is adequate for the proposed uses, . ' Page 1 •, y 4' o , • • ' ! „ " y ,." ' S 41 i r r Al .rt `• r The subject property is part of the approved Westlake Overall Development Plan and Schedule. It is identified as Multi-Family Phase 8, with a maximum density of 391 units. The site was part of the original Westlake Planned Unit Development approved by the city in 1981. Some modifications to the original Westlake PTJD Plan has occurred, however, the overall planned land use, density and traffic patterns have remained basically the same since the original approval. This project was originally submitted as a 360 unit project. In response to neighborhood concerns regarding the row of buildings along Parkview as well as city staff's concerns of perceived project density, configuration and deleted 3 buildings we have revised the building type "D" total. t ! 1.,1 • t`i One of the buildings was removed from the Parkview Drive area with the other 2 being removed from the inner recreation center area. Overall 8 units were deleted resulting in the current total of 352 units, III. EXISTING SITE CONDITIONS,- • x y Surrounding land uses and development patterns are shown on Sheet A2. Multi- '4 family residential and a church exist to the west. Commercial uses and a single family residence on a small farm exist south of the site across Kruse Way, The Lake Baptist Church (under construction) is to the east. To the north is Parkview Avenue and single-family residential development. A large area of wetlands exist T ? S= across Parkview from the northwest property corner. The site has a slight slope of 4%, dropping approximately 40 feet in elevation from the northeast property corner to the southwest bound arydelineated on the enclosed Slope Analysis, Sheet A3. The•site has ohese n y oneesetree greater than 8"(1). This is a 16"4, apple tree in the southwest corner. Otherwise the vegetation is mostlymeadow grasses. The project includes three narrow, man-made just ditches, two on site and one j off the site to the south. These have been• � identified as wetlands and are described in the Wetlands Delineation, Evaluation and General Biological overview. The south ditch is described in a report from the J.D. White Company entitled Wetland Delineation of the Westlake II Development P nt Property, dated November 1991, Both documents are included in the Appendix, , • The treatment of these wetlands will be discussed later in Section VI (4.005), The Preliminary Subsurface Investigation included in the Appendix, describes"generally uniform subsurface conditions" prevalent on the site, The conclusion of the report is that tho proposed buildings may be safely founded on spread footings, This soils data will be utilized to determine appropriate construction techniques for buildings, roads, parking and utility improvements.

COMPLIANCE WITH COIVIPREHENSNE PLAN STAND R1►lS • a Urban Service Boundary Policy "ILL The City will TvIraage and phase urban growth within the Urban Services Boundary, with a logical planned extension of basic services. To establish priorities for the phased extension of services, the City will identify areas within the Urban Services Boundary .as follows. (1) Lands suitable for near future development (IMMEDIATE GROWTH) (2) Lands in long range growth areas (FUTURE UR.BANIZA.BL]E). The subject property is within an "immediate growth" area. All urban services ' . • are available to the property. The development of the site is consistent with j • the above-stated priority for development in areas where services are available. This infill policy 'promotes orderly and efficient use of the city's investment in urban facilities and services. Impact Management Policy, "I. The City will protect natural resources and processes from adverse impacts of development, within reasonable cost limitations." ,. „. . Only the tree (16" apple) exists on the roe 1 property.r ' Wetlands have been delineated on the site. There are approximately .56 acres of jurisdictional 'wetland area. The natural resources and processes associated with this area will be protected through the mitigation and enhancement actions identified u on the wetland mitigation plan. All work within the wetland area must also be approved by the Oregon Division of State Lands and U.S. Army Corps of Engineers. . "IL The City will evaluate zoning and development proposals comprehensively for their impacts on the community, ••• ° developer to provide appropriate requiring the �T solutions before approval is • y ,• granted." Z . The potential impact on the community will be mitigated by imposing appropriate conditions of approval on this development, ', • "DI. The City will require new development to pay an equitable share of 4 the costs of public facilities, particularly sewer, water, drainage arks open ► P ► p apace and streets or traffic improvements." The developer will pay an equitable share of the sewer, water, drainage, open space and traffic improvements. There are no park improvements required on- site. The new Westlake Park serves this site. Page3 w A. f • •r Y , I Y Weak Foundation Soils Policy et' : "I. The City will identify areas with a potential for low soil strength and {�` indicate the degree of potential hazard." , ` The site is identified on City Maps as having potential for severe limitations due to weak foundation soil. However, the attached soils investigation indicates that the soils are adequately firm and suitable for the proposed residential development. This finding was adopted an part of the previous ' • approval for the site. Wildlife Habitat Policy "II. Development in the planning area will be encouraged to preserve wildlife habitat" The site is an open field that is surrounded by urban levels of development. It has relatively low habitat values because there is little variety and structure to the vegetation. T1.4 principle wildlife type in the area are songbirds. The wetland area is currently dispersed into a series of manmade drainage swales and a new detention pond constructed for Westlake '89. The proposed • mitigation plan will consolidate the wetland area, add ponds, and add vertical layering of the wetland and upland vegetation. These actions will increase the '-_ $ diversity of the habitat by providing new niches for animals. Wetlands Policit "I. The City will identify wetland areas which are essential to stream `•. channel protection, water quality and retention of storm water runoff. These will be designated as Protection Open Space. 'r b n "II. The City will establish development standards which will preserve the natural function of these wetlands and protect them from r a l deterioration." r. The applicant has surveyed the property for wetlands. There are .49 acres of delineated wetlands on the site. There is an additional .07 acres wetland area between the south property line and Kruse Way that will be filled when the `.c. . entry traffic lane is constructed. The total area includes this .07 acres impact area giving a total of.56 acres. These wetland areas are dispersed on the site y• along several drainage ditches. The city has not designated the site as ,. "protection open space". The proposed Westlake II mitigation plan, though more heavily planted, is intended to carry the wetland character of Westlake Meltdown site down to Kruse Way. This will maintain, facilitate ant? guarantee a wetland and , rrw Page n 4h` e • J f e, j L •+( riparian link along Carter Creek adjacent both subdivisions, Westlake II land gradient reflects that on the Meadows' site, resulting in the same pool and r riffle concept of mitigation hydrology on this new wetland, weirs will 'Y ` slow and hold water in pools. Pools and associated emergent vegetation help clear water of sediments and other contaminants before it leaves the site The new wetland will possess the following major functions: 1 (1,) Wildlife habitat and linkage ;2) Storm water retention ' (3) Storm water filtration 4 ( ) Open space and greenway link (5) Education Protection of the new wetland will'be accc At1:•//shed by means of a buffer 1 ° ° planted with emergent, riparian and upland plants. A four foot high fence around the mitigation and storm water detention sites will further detour physical intrusion into the sensitive area. The mitigation plan has been reviewed by Bill Parks with the Division of State Y Lands and discussed by phone with Mr. Gene Herb with the Oregon Department of Fish and Wildlife. Both Bill and Gene have approved the plan . in concept. Mr. Herb noted the importance of fencing to protect the habitat. both expressed the importance of linking the two wetlands, Meadows and Westlake II by extending the scrub shrub and ash tree canopy south. Before the start of construction, a joint Division of State Lands and Army Corp of Engineers Permit will be applied for and received. A copy of the V permit application is enclosed as a part of this submittal. r As a condition of the wetlands permit, the Division of State Lands will I a three year monitoring program with accompanyingrequire ". r reports on an annual '+n basis. Stream Corridor Policy "U. The city will establish policies and procedures which will protect stream corridors. Policies will emphasize preservation of natural features, especially trees, vegetation and existing streambanks and protection of water quality." • The site does not currently have a "stream corridor", made drainage swales (which flow intermittently), TherIt has a e are nor n trees.ies of man- , The "riparian vegetation is field grays. The proposed mitigation plan is intended to protect and enhance the habitat and water quality values associated the water course through the property by consolidating the wetland, makingand and diversifying the vegetation, ponds g ge These actions will create and protect a defined stream corridor, in compliance with the above policy, µ f; t. , ct • Page 5 . ' hr�F ( i t t I ti. • Energy Conservation Policy ':. , •,"II. The City will encourage energy ion through land use planning and site and buildingdesign review". • One of the most effective ways to promote energy conservation use planning is to concentrate nigher densities along transit routes. Thheland subject property is adjacent to Tri-Met Route 38. The proposed density is units per acre. This is relatively high density and the location is appropriate for promoting transit usage. f < ..i ` i Residential Site Design Policy (" City" • The • a will require new residential developments of four or more units to meet minimum criteria for overall site design which include.. a. preservation of open space 9 r, b. preservation of natural features compatible with structures ti and site r' • c. efficient, energy-conserving street and cir j d. safe, convenient _. @ culatimn 'stem . , I strian.and bicycle emulation e• drainage management compatible with natural f. privacy and quiet hydrologic Qic systems g. energy conservation b h. protection of buffering,from adjacent. streets uses and k I. building placement. •.+' ' ��` Additionally, the City will developments of four or more all new Ii.-0, R-3, R. residential units meet minimum criteria for: j. variety of building types and designs and ' k. building$ � appearance aesthetic amenities." Please see the building and site design aspects of the proposal as described in Section VI of this application. The site plan preserves open space and natural features by providing a consolidated wetland area, ` ` " efficient because a large number of units (352) are served circulation 'stem is roads and a system of driveways, as opposed to dissectingthe s site with public streets. The north-south pedestrian corridor provides a direct path from Kruse Way to parkview Drive. Drains e " part of the hydrologic management has been planned as system of the mitigation plan.

Transportation Policy "I. The city will develop a balance transportation system Which will provide safe and convenient access to serve the approved land use pattern within the urban services boundary. This system will include . • major streets as well as neighborhood residential streets." , • • "IV. The city will develop a residential neighborhood streets system adequate to handle expected volumes, but at minimum necessary scale to preserve the quiet, privacy and safety of neighborhood living." r • ' • The original DRB approval for the Pointe South apartments found that the transportation system in the area was adequate for the projected traffic. This finding was appealed to the city council, who directed that a traffic study be r. • prepared. Although that direction was nullified by a subsequent LUBA case (the Hoffman case), the applicant has prepared a traffic study to fully document compliance with the above policies. That study concludes that the• site can be developed as planned with minimal traffic-related impacts to the ° , adjacent street system and nearby intersections. The basis for this conclusion is summarized in the following excerpt from the Traffic Report. h "is The key signalized and unsignalized intersections within the study area are " currently operating at an acceptable LOS during weekday morning and evening peak hour conditions. a Upon completion of the development, the site driveways and key off-site intersections will continue to operate within acceptable level of service limits during them morning and evening peak hours under either of the access alternatives. , is The Westlake Drive/Kruse Way intersection will require the addition of a right-turn lane on the westbound approach to the intersection to be able to accommodate projected year 2000 traffic volumes. si Both the northbound and southbound approaches to the Carman R Drive/Kruse Way intersection will need to be widened and improved to (, allow for the provision of separate left-turn lanes to be able to accommodate projected year 2000 traffic volumes. �., `,' i• • a The improvements identified above will not be warranted upon completion of this development, but rather will be necessary at some time in the future as traffic volumes within the study area begin to approach the year 2000 forecast levels. It is important to note that these improvements will not be warranted upon completion of this development, but rather will be necessary at some time in the future as traffic volumes within the study ." area begin to approach the levels identified in the year 2000 forecasts. a There are several distinct advantages associated with providing direct access Y Y to Kruse Way via a driveway located midway along the property frontage.

Overall Proportions v„1 The Westlake neighborhood has both single family and multi-family residences as well as some institutional buildings including the new fire a'�'ation, the LDS Church # ` and the proposed Baptist Church now under construction. The existingstructures4 share a number of similarities: beveled siding painted neutral tones, wood deck rails ' with some metal detailing, wood trellises, residential window groupings with wood ..._:,,,:,:,.... ` trim as well as wood fences.r There are a variety of roof types and roofing materials. A , Westlake Meadows Apartments have gable roofs extending down to single story with concrete tile roofing. Most of the houses are hipped or gabled with, wood shakes or shingles. The new fire station, which is very residential in character, has beveled , siding and architectural grade fiberglass shingle roofing. Building heights in the '` neighborhood vary from one to two stories plus a loft (2V2 stories). This project features materials and forms consistent with thane found throughout the Westlake neighborhood. The residential buildings have bevel siding, wood and A N metal rails, and wood fences. Wood trellises are used to mark entrances and add visual interest and variety to the buildings. They also make a strong residential statement. All of the proposed buildings feature bay projections at some of the f upper level spaces. The hip roofs are relatively complex. The architects have t broken down the building massing so that instead of long runs of monotonous straight walls, the facades have what appears to be a small group of single family , , homes only marginally connected by subordinate roof patterns. This results in buildings with smaller, more intricate roof planes and building images that are very compatible with the prevalent single family residential pattern of the area. The roofing material will be architectural grade fiberglass shingles. This material was `selected for the prominent shadow lines, but also because of the intricate planes of the roof. These shingles will give a clean, precise appearance and will be low t maintenance. Overhangs project a minimum of 2' and roof slopes are 4/12 giving the buildings a lower profile residential lock. . The community building is located on axis with the entrance drive off Parkvievv �" Drive. The entrance to the building is marked by a central gallery with a series of tall shallow curbed roof forms that at once identifies this as a special commercial building and center of activity. It is also an important P symbol referencing the i `• • Agrarian history of the district. Otherwise, this building uses' similar details, w materials and colors found on the proposed residential buildings. continued through the community building to the swimming p This entry axis is f area where, on the north aide o ► an open air gazebo is located. To the south of the pool area, the visual x ' .1 axis is terminated bythe bathhouse. This This structure is also marked by the shallow curved roof form.

The stairway handrail detail is similar to the guardrail detail for second level decks which will provide design gn continuity, These deck and stairway/railings have been designed with a heavy wood top rail with metal railing sections below. This combination of different materials will provide interest and color opportunities for the buildings. F 2.02 (le) A V} x 'J r f. Use trees and other natural elements to help define building proportion relationships and to provide scale to the structure as a whole. A combination of deciduous and evergreen plant materials have been carefully proposed around the buildings to enhance the facades, accentuate the entries and provide privacy where necessary. r' g. Limit the variety of styles of building elements. The residential buildings and the community building both use the same a w architectural vocabulary. This combination of forms, materials and finishes will provide design consistency. ' "I a h. Screen mechanical equipment from view, or place in locations a. where they will generally not be visible. See 2.02 (id) above. , L Every attempt shall be made to design and locate buildings to provide access to desirable views, while not blocking the views of others unnecessarily (density reduction not required). The Site Plan, Sher..4t Al, clearly shows how buildings have been oriented to off site .. views. On-site "view amenities" have also been prioritized. Building clusters relate to each other forming open spaces that will be treated with landscaping to become visual amenities. One such grouping of building clusters is at the center of the site. The swimming pool/bathhouse plaza will be oriented onto by seven relidential structures from three different building clusters, Perimeter buildings orient over ' landscaped berms, wetlands and through landscape buffers to distant views, The W buildings have also been carefully sited to enclose parking areas which will improve , security and enhance the Parkview streetscape on the northern perimeter of the site, r , 2.

This relative flatness allows buildings to be clustered around parking courts. This maximizes resident `' ' convenience while, at the same time, effectively conceals the parking from surrounding on-site and off-site neighbors. The apparent size of these car courts is a minimized/broken up through the placement of landscape islands and carports in the ' ' ' center at the points of access. These building clusters relate to one another to form entry plazas and semi-private open spaces. p P p This results in a highly ordered site plan of identifiable building clusters or villages. l s J • b. Design foundations to match the scale of the building being supported. Bernning, resiting, or sheathing the foundation structure with wail siding are examples of methods which accomplish this purpose. See 2.02 (1d) above, c. Use decks, railings, and stairs to relate re building to the contours ,; of the land. All of the residential buildings have low fences enclosing grade level patios. These ' '4. ..• fences will be clad with rough sawn siding and will have heavy wood top rails. To t add interest and to provide for views, each front fence has a square cut out .. 'x brace. These fences will be painted warm gray to compleent the siding color an and the wood detailing will be painted an accent color. S. Buildings shall be designed to minimize the personal • users and to minimize the tY of opportunities for vandalism and theft. Building hardware that discourages forced entry and provides approved A' capability shall be used. egress ' r These buildings have been designed so that there is no front, back or side elevation. r Each elevation is considered prim ary ary with entrances and/or major window ' groupings. This facilitates easy surveillance of all open spaces, parking areas and sidewalks. This is very effective in deterring vandalism and theft. Building entrances have no blind corners where an intruder might hide. Landscaping is low at entrances for the same reason. All entrance doors will be solid core with dead bolts for security. Side lights have been excluded for security purposes as well, ' Lighting will also discourage crime. See the Lighting Plan, Sheet #16. 4. Building shall be designed and constructed to reduce noise impacts on interior occupied f p spaces and adjacent property. a. Use solid barriers such as fences, berms, natural landforms and • structures to reduce sound levels.

No noise generating parking orients onto neighboring properties. ", The recreation center which will be the hub of activity for the project is located in the center of the site. This will minimize noise impact on neighboring properties and surrounding streets. All perimeter buildings are buffered from neighboring '`,`,3, properties through the use of berms and extensive landscape plantings. b. Minimize the window surface on sides facing adverse sound ; sources, where possible. ; Of the 29 residential buildings, only 2, containing only 16 units total, orient toward themajor sound source, Kruse Way. Both of these will be partially buffered with `� ' berms and landscape plantings that are in addition to the existing plantings parallel 1' to Kruse Way. c. Heat pumps, or similar mechanical equipment shall be located so , - Y• that operating noise does not affect use of living areas such as bedrooms, outdoor decks or patio areas and adjacent property.4 1 • :. 4 The only mechanical equipment on site will be the condensing units at the j community building in the center of the site. These will be placed as far as possible from the residential units and screened to minimize noise impact. } 5. Buildings shall be designed and constructed with roof angles, overhangs, flashings, and gutters that direct water away from the structure. The hip roof configuration gives positive drainage to the gutter system in all cases. These gutters connect via drain leaders directly to the proposed underground storm drainage system. 1 2.02 (g) '' 4 N/A . � r Y $1' 3.005 Stream Corridors • The site contains one perennial drainage channel which enters the site from in the northwest corner from an existing culvert under Parkview Drive. The channel originates a several narrow ditches that collect surface and subsurface waters and divert them to the western edge of the site. This incoming water flows in a narrow and shallow channel parallel to the western site boundary. , • Within 150 feet of ": entering the site, the channel becomes deeply incised and flows in a straight path southward. It terminates at the southwest corner of the site adjacent to an existing detention pond, where it enters a concrete culvert under Kruse Way. At Its ` t southern terminus, the drainage channel is 4 to 5 feet deep and 3 feet wide. The drainage area is vegetated with willow species, hawthorn, spires, meadow (oxtail, fescue and velvet grass. Page13 tl .:q�• ," • r . Standards8.020 for Approval The improvements proposed in the stream corridor are limited to drainage i•' improvements and revegetation. The proposal includes relocating and reconfiguring the existing man-made drainageway along the western property line. Improvements t will include: recontouring the stream bed to a more naturalistic, free flowing form, installing a wier structures to control the flow rate and maintain moisture levels, .' extensive revegetation with riparian plant materials and perimeter fencing to protect the habitat in the area. The buffer zone around the new stream corridor exceedse 25 feet required bythe the Development Ordinance. The improvements proposed in the stream corridor are in compliance with permitted "types of development" allowed in the stream corridor [3.020 (43 A-E)].' , An easement or tract will be defined over the drainage area ensuring access for storm drainage maintenance requirements, tv 4.005 Wetlands �' The wetland areas on-site consist of three narrow man made trenches that traverse different portions of the property. One is in the northern portion of the site and slopes from the east to the western edge. There it connects with the second trench 9 r •' h r�'• . which slopes to the south and extends the length of west site boundary. A third trench or swale is located parallel to Kruse Way in the southeast corner of the site, This nwale slopes to the east extending onto the Baptist Church site (under construction) and terminates near the Kruse Way/Carman intersection. Refer to (A2) site analysis for mapping of these areas. In addition to the delineated jurisdictional wetlands, which total .49 acres, there is an existing storm water detention basin located in the southwest corner of the site. This facility was constructed as part of an earlier phase of the Westlake PUD to regulate the volume and flow rate of stormwater entering a culvert which extends to the south under Kruse Way Boulevard. The method proposed for addressing these wetlands is to eliminate the two trenches n ..1. that traverse the site in an east/west direction and consolidate them into one larger riparian zone along the western site boundary. This facilitates creating one large, high quality wetland habitat area that is an extension of the drainage corridor r"\ . •; established to the north with the Westlake '89 single family development phase. • • s:' This riparian wetland area will extend from the northwest corner of the site, where " southwest of the site where it flows to the it picks ut stormwater from the culvert under Parkview Drive, down into the existing storm water detention facility. This riparian area will be recontoured and•vegetated with wetland material to match the northern Westlake '89 drainage corridor. The detention pond will also,be modified and enhanced with ripariang vegetation, A 4 foot high chain link fence will enclose the area, meandering through the wetland plantings. Refer to the • landscape plans (L1.4) for a detailed description of revegetation efforts. Page 14 A r i t l ,‘..,.,• • i " [.' I. 1. 3 -p r: The site grading and drainage systems are carefully designed to integrate with this r ' wetland corridor and pond. Stormwater runoff from the buildings and parking areas ' will be collected and conducted in pipes to strategic areas located next to the t wetland. The stormwater will outfall into a network of smaller basins and swales parallel to the wetlands, These grass-lined basins and swales will provide •' >. biofiltration, cleansing the water before it enters the wetland corridor and detention pond. The basins and swales will also provide additional stormwater storage ' volume, ensuring that stormwater enters the wetland corridor and main detention pond at the appropriate rate and velocity. This method for wetland mitigation and enhancement has been discussed with representatives of the Division of State Lands and the Oregon Department of Fish and Wildlife. These agency representatives, who will be primarily responsible for • • wetland permit issuance, concur with the proposed improvements. Final grading and planting design for the wetlands will be prepared and a ., nationwide wetland permit application will be filed concurrent with project final design and construction documents. For further reference, the appendix contains +•' the wetland report prepared and submitted with the initial development review • application as well as an updated memorandum from the J.D. White Company ' " regarding the wetland swale located in the southeast corner of the site adjacent to Kruse Way Boulevard. 5.005 Street Lights . , 0 As discussed in 2.02 (id) building entrance lighting will be accomplished with h wall mounted fixtures at each unit. Car courts will be illuminated with fluorescent fixtures mounted behind the headers or facia of the cElrports. This will effectively - eliminate glare. • g t • , Internal access drives will be illuminated by pole lights with cut offs to minimize glare. Existing street lighting along Kruse Way and Parkview Drive is will remain. On-site walks will be illuminated with low level garden lights and post mounted lights. See the Site Lighting Plan, Sheet A16. The manufacturer cut sheets on "••'' proposed fixtures have been included in the Appendix for further reference. 14 yi 6.005 Transit System Tri-Met Route 38 currently serves the Kruse Way corridor.

The efficient' of the proposed building types and parking areas results in proposed landscape area well in excess of Lake Oswegocode requirements., 4 q The orientation of the structures on site provides excellent opportunities to create dynamic outdoor spaces and an appealing r ! Aid y streetscape along both Parkview and Kruse Way, Street trees are proposed at 30 foot intervals along Parkview Drive across the entire frontage of the site. These Ash trees will match the existing trees on the north side ., of road as well as the trees to the west in front of the Westlake Meadows apartment ~`,: , complex. The Ash trees will also extend into the site leading motorists up to the • r u* recreation center. Ash trees (different varieties) will also be planted along the interior site roads as well as in parking lot islands throughout the project. The ' planting along Kruse Way is designed to blend into existing planting and provide buffering from traffic noise, The street trees are held back from the site entries to ., provide the required site vision triangle needed for motorists and pedestrians.

The pond was built during the construction part Westlake '89 as a regional detention facility and is already covered byof public easement. It is presently capable of detaining 48,000 cubic feet of sting while releasing 8.61 cubic feet per second. Under this project, it is runoff, proposed modified to accommodate a 13,750 dry) filtration 750 cubic feet (ordinarilyp p ed to be pond in the F ` east end of the easement. To compensate for the area used for the filtration more detention area is to be added to the north. An easement is proposedton pond, s the added detention area. The area immediately upstream from te l to most ' southerly "check dam" is below the overflow elevation of 253°. It is proposed to included in the detention volume and to be covered by the now detention to be easement. ` The proposed drainage system is to be private, employing Lynch e catch and cleanouts at every 100 feet in rIcordauce with the UniformedPlumbing es Run-off collected by the proposed private drainage Code. } system is to be discharged into a ' • rp"dry" filtration pond out of which the runoff is to seep into the detention one,,. While the emergency overflow of the detention pond is at elevation 253 p of the filter dam between the detention pond and filtration pond is at elevation 2 , which will ensure that at the worst flood condition, exceeding 25 year 52.6 event, the two ponds would become a single body of water before it overflows , • Kruse Way. Such designinto • . is proposed to maximize the detention volume. `• The volume of the filtration pond is calculated using elevation 252•6 as the , surface elevation. Run-off flowing from the east in the existing drainage `water to Kruse Way is proposed to be discharged into a new ditch inlet to be constructedt � over the xistirgs culvert taking the drainage south, accross Kruse Way, Thee ditch is more than adequate for the calculated drainage comming from the east. .” Sanitaryh Sewer System '� Ar Sewage from this project is proposed to be discharged into an existing8-inch line extended through the adjacent property , in the southwest corner of the project, rops the to the ending at an existing manhole developed while property to the east � north of the site is already line east of the project.

Sewer lateral lines outside the public easement are to be ':,; - private, serving only one building each. The system is designed to locate all manholes either in the vehicle accessible area or -AI 1 ` ryr _ immediately adjacent to it. Water System The proposed water system is to be line tapped to the existing 12" line in Park View , Drive, north of the project as well as to the existing 12" line along the east side of the project located upon the Baptist Church parcel 18 feet from the property line. The church is agreeable to granting a minor public easement necessary for this 4; connection. • Both 12" lines where connections are proposed are served by the Touchstone ?. Reservoir Service Level with an overflow elevation of approximately 475,°. The highest floor elevation of the proposed development is 287.° which would experience a pressure of 81 PSI. The lowest floor elevation is 257.° which will have even higher pressure. To limit the maximum water pressure to 80 PSI will require the use of a private individual pressure reducer at every on-site water meter including irrigation meters. t According to the City Fire Department a fire flow of approximately 4,900 gallons per , minute is available at the two 12" lines where the proposed water system is to be connected. To ensure that the above flow is made available throughout the site, a 10" diameter loop is proposed through the complex, with 8" short branches from the loop. Such design will ensure the maximum velocity in the looped 10" pipe of about 10 feet per second. In the placement of fire hydrants on-site the criteria applied is to have no point of a building further than 250' from individual hydrants.

This report describes existing .i• ,; _ hydrology, soil and vegetation conditions which pertain to x a wetlands . The wetland boundary defined herein marks the ;„ $ .' location and extent of jurisdictional wetlands. The proposed Pointe South Apartment (PSA) site is located ' north of Kruse Way , south of Parkview Drive (planned extension) , east of Westlake Meadows apartments, and west of t the proposed Lake Baptist Church site, Lake Oswego, Oregon (Figure 1) . Access to the site is best gained from the east terminus of Parkview Drive. The project site occupies approximately 21 acres. The topography gently slope, to the , southwest, and slight east-west undulations separate the • <` ., parcel into two drainages. A small perennial drainage channel flows from the Property to the north. The United States Geological Survey (USGS) at � Lake Oswego, Oregon quadrangle map (1984 revised) shows the site elevation ranges from 290 to 250 feet above the national geodetic vertical datum of 1929 . �' r • Along the southeast edge , an off-site perennia channel runs parallel to the southern property line. drainage Until recent zoning changes and housing developments, the PSA site was used as open pasture for cattle. Several fallow years have nearly erased any adverse impacts created by 3 grazing . During the past winter or spring , a drill rig investigating geotechnical conditions made some disturbances a. (deep tire ruts) while moving from one location to another. 4. The consultant team finds that approximately 0 .22 acres of wetlands fall within the jurisdiction of the US Army Corps of Engineers , Portland District "" (COE) and are subject to ' restrictions and permits required by Section 404 of the Cle•„i 1A Water Act. Approximately 0 . 1 acres are affected by the current site plan, all of which fall under the Nationwide-26 program as less than 1 acre requirement. An extensive mitigation plan and stormwter detention area is proposed • separately. 1 ' 1 at '�t .1/ y . Ate,. _ .. .. .. .. 't'�.. .. �,. �'.�. ... T. •.. r. .y ...� �. t j -j ly A • d t 1 T .

" (33 - . •A. The importance of wetlands has JA,; '` increasingly been '' recognized by the public as well t 1, as developers and regulators . • In order to protect wetlands , federal and state legislation has been enacted to preserve wetland values and functions. The US Army Corps of Engineers (COE) has • ` filling of wetlands through the Clean Waterrisd�.ctian over Act. The US . Environmental Protection Agency is responsible for reviewing all COE • , permit decisions regarding wetlands . The Department '�" of• State Lands �' • (DSL) has jurisdiction over dredging of wetlands and concurrently issues a permit with COE. • Procedures Procedures utilized were 1 C ) pre-field site evaluation ` t procedures which included the review of Washington County soils data, the review of U.S . Fish and Wildlife Servic •A� wetlands maps of Washington County, de reports from, the Brunick property to the north a and iew of wetland procedures. (2) field ' . Field procedures were divided into three separate t,!I ' ' � • segments, theyWere: � " (1) the site was walked and photographed , . ( 2 ) vegetative samples were taken of every different identified plant species or clump of plant species that could be found on the site. Plants were identified in the` Ix taken to the Creso Herbarium, Pacific Lutheran Universityfield and w '<� confirmation and identification to subspecies or p for ` "' possible „ and (3 ) group, if preliminary data collection on soil and hydrological conditions by Phil Scoles of Scales Associates , ' Inc. From these surveys, the , _r general physical parameters, and a approximation of the wetland boundaries were determined. . 0 w Ie • k ��. 3 1 y • II (.I • '' .A` P } .. n� Wetland determinations were made using the techniques •m:: described in the Unified Federal Manual for Identifying and f. ` DelineatingWetlands �(COE, 1,989) . The methodology focuses on the three wetland criteria listed below that must be met: X M 4 '.l-1 1. It -must be inundated or saturated with water at some ! time duringthe ' growing season of the prevalent `! S s ,y ) and vegetation (usually at least seven days) ; 2. It must have hydric soils, which are soils that are saturated or flooded long enough during the growing season to develop anaerobic conditions, and y;. w 3. It must SU .. Pport a prevalence of hydrophytic (water- ` loving) vegetation. Prevalent vegetation is defined as the species that are dominant in a community, k usually measured by aerial cover greater than 50 percent. • r ' . There are some exceptions to this, for example, in cases " where one or more of the original elements (hydrology,} ( }' gyr soils 1 . or vegetation) have been disturbed or altered. The PSA site • was evaluated having no disturbance, because the hydrology was channelized probably 25 years ago or more. A. Project site was surveyed on August 30, 1.989, Septe mber tuber 3 , 1989 , and September 6 , 1989 by Rex Van Wormer, Senior Biologist, IES Associates aild on September 6, 1989 by Phil • Y Scoles of Scoles Associates , Inc . A detailed vegetative • analysis and wetland flagging were completed on October 2, 1989 by IES Associates. Soil and hyrology y gy conditions were studied on September Ar 23 , 1989 by Scoles Associates, Inc. , and on October 2, 1989 by IES Associates,. Their field observations are recorded on data i "X sheets (see Appendix A) and their wetland determinations are ' summarized it the next section. ``•' Three soil transects (A,B, ',�, • and C) and one other location (D - adjacent to tire rutting) v • "' ` Were investigated. g Four vegetative transects, on the same 0 , transect lines as soils A, B, and C, and a cross transect of 4 ` • • ,,.. C r y, ;l • + Ii ti the existing drainage ditch were also investigated. •, %Y given the size and "facultative nature of the °' property, the intermediate-level survey method was chosen for use in this study. At selected points on each transect, wI Percent < <� vegetative cover was visually estimated for each plant spe+,cies observed within a 5-foot radius for bryophytes and herbs; and a 30-ft radius for trees, shrubs, and woody vines. Additional p • t . species were occasionally recorded if their lresence .near the ;• s point being examined was considered important (particularly if Y obligate, facultative wet, or upland species were observed) . Hydrology y gy and soils were evaluated at the center of these `' areas using a hand bucket auger. Results a; i Discussion Hydrology : : 4 '" Existing Environment The hydrological' features of the PSA site include one perennial drainage channel and a diffuse drainage a tern " directs surface water runoff to an off-site ditch. These ' features are shown on Figure 2. • A perennial drainage channel enters the PSA site in the . notthiwest corner from a gently sloping plain that extends north into the next property. The channel ' originates as several narrow ditches that collect surface and subsurface waters and divert them to the west side of the Westlake ' 89 ' site. Additional hydrology information about the Westlake ' 89 site is specified in its wetlands re ort (Anderson and Scoles 1989 ) . The incoming water flows in a narrow and shallow `. ` channel filled with low herbaceous hydrophytic plants. Within 150 feet of entering the site , the channel becomes deeply incised and follows a straight q path southward . A small earthen bridge crosses the channel in Its lower reach and is + a presumably the same age as the drainagechannel . At its southern terminus (a concrete culvert) , the drainage chantel is 4 to 5 feet deep and 3 feet wide at the bottom. The • 5 11 � i y y ' i I.,' e� r.." .ti k .7 s • �A> 1� i culvert directs the drainage water under Kruse Way and into another ditch system that eventually becomes a tributary to '�' " Fanno Creek and then the Tualatin River. ' 1 W The eastern half of the site is topographically separated 1 by a slight undulation. The drainage pattern curreni:ly directs some runoff to the south edge of the property as observed by some matted plant material . At the southeast t' • edge, a drainage ditch runs parallel to the property carrying u ..'' runoff and spring water from the Lake Baptist Church site. The ditch terminates at a culvert similar to the perennial ••' drainage channel and crosses under Kruse Way and enters the . same ditch system. Since this ditch is located off the PSA N;' property , it was not delineated for wetland status . $ '+tir :, Additional hydrology information about the Lake Baptist Church site is specified in its wetland report (Anderson and Scoles , 1989) . The historical hydrology of this site was not evaluated since it has been a pasture fc,r likely more that 25 years. The apparent "age" of the drainage features seems the same, and some channel maintenance logically occurred. Based on the prevalence of hydric soil characteristics (low chrome, matrix ' , � :)' and mottling) , it i quite probable that the site historically remained wet for significant period into the summer. The diffuse topographic changes over the whole field tend to suggest that overland flow ollowed grass-lined swales and water may have seasonally ponded in several areas. Wetlands Iydrology Determination : I . Wetland hydrology y gy is defined by the presence of regular .` (seasonal ) water inundation or soil saturation up to the surface at some time during the growing season . At the time of the field study, such inundation or saturation was apparent "• pparent " � ' onlyin the ` � • perennial drainage channel . The shallow section of th.e channel (in the northwest corner) had some saturation / ' near its u � � .'� : upper bank, but saturation in the southern end of the channel was confined to the bottom. The southernmost data ;:. points of Transects B and C, has wetter soil conditions in ajrm°, comparison to the rest of the site . Although actual t�` , a 6 : r 4 f�+ � !. 1. 'P , _»i w.,` 16 fi . 4 A t Y.. , III k.• saturation was not visible ( due to the late season • ' • } j determination) , it '' a ppears. that the southeast property edge hat sufficient wetness at an earlier time of the year to i 1 ' qualify having wetland h drolo .: Y gy. Positive wetland hydrology indicators, such as standing water, saturated soil , wetland . drainage patterns , and hydric soil characteristics were E" . evident along the drainage channel during the site visit.

These are the Aloha silt loam, Cove silty clay loam, and Huberly silt loam. All are described in great detail in the Soil Survey of Clackamas County Area, Oregon (Gerig 1982) . ':a { For this site, these range from deep somewhat poorly-drained upland to deep, very poorly-drained footsiopes. Figure 2 also shows the different divisions of this soil type (mapping in 9 •r`;, ' . units) as delineated by the Soil Conservation Service (SCand refined by the soil scientist during the site evaluations) r . The upland and broad sloping areas in northern half of the property have somewhat poorly-drained soils (Aloha soil •'' + series) that •have formed in stratified glaciolascustrine deposits and have silt loam to loam soil textures . This soil ar has a very dark grayish brown (10 YR 3/2) silt loam topsoil � . v. layer about 9 inches thick. It has no mottling or indication of soil saturation. The subsoil , from 9 to 48 inches, is also a very dark grayish brown (10 . YR 3/2, slightly g y grayer) silt 1A load . It has some clay accumulation and many faint to • distinct dark brown mottles (7.SYR 3/4, prominence increases with depth) . There appears e .; no significant soil col,,: difference between the center of the property and the top of the drainage channel . g A weakly developed fragipan (a brittle , and slowly permeable layer) exists in most of this soil type ` at a depth of 28 inches .P The substratum (unweathered soil material) is a stratified f;.ne sandy loam soil without coarse fragments. • This soil type has 3ome development restrictions due to shallow depth to ground water during winter ar.d early spring, slow permeability, ,. and droughty summer conditions . The Aloha • silt loam is classified as Aquic Xerochrepts , which means this young soil has a predominantly xeric (dry) moisture regime that is partially saturated by the rainy season. It is not • listed as a hydric soil by the Soil Conservation Service (SCS, 1989) . • 9 • DA�..

The wetland mitigation and grass line swale plans for the Pointe South Apartrtlents provide mitigation and improvement for =f,`' { the filling of the' narrow drainage ditch located on the west •1. side of the property and for surface water runoff treatment. The existing wetland consists of a vertical sided drainage ditch with limited amounts of Veronica americana ll) , d'uncus effusus (softrush) (speedwell) , parsley) . The banks of the existing~nthe sarmentosa (water- a arsle ditch are vegetated with a mixed strip of RoY.._sa 2asocarpa (pea-fruit rose) , Rubus discolor (Himalayan blackberry) , and Sal willow) . There are a half dozen scattered red alder (Alnus rubra) along this portion of the site. '° The grass line swale, which is part of the surface water runoff treatment system, is designed to allow sufficient length and duration flow-through to satisfy the required in %conditions for waste water treatment as identifiedthe referenced literature. the • The grass line swale has been incorporated with the existing drainage ditch incorporating the two systems , aaneing Kruse Way gy enhanced surface water treatment can be devised which will not only reduce the potential of sediment and contaminate levels reaching the retention pond but will also improve of the qualityy of the road runoff surface water that is currently beingdischarged through this portion of the drainage ditch downstream. The • retention pond design has been modified to increase ' � character, wetland '��� provide biological diversity, and to improve the • quality of the water being discharged under Kruse the culvert.

The enhancement portion of the • proposal • will consists of 4 the replacement of the drainage system along the west edge of the property to provide continuing water movement through this i• area and to create a visual and hydrological continuation of . . the proposed wetland enhancement/mitigation plan for Bunick property located north of the Pointe South Apartments site.

(Planting plan of low flow stream cross . , `'. sections are attached. ) Vegetation : �I • • selection foryYb The plant the low flow channel and 2.5 :1 side slopes was selected for (1) its biofiltration and sediment removal capabilities, (2) its ability to compete with• reed canarygrass, hardhack, or other invadingtype ype species „'. ! ,that create monocultures , ( 3 ) plant height and growth characteristics, and (4) its wildlife benefits. The majority of the shrub species selected are either seed, berry, or fruit producers that provide a diversity of wildlife for passerine birds and -reate flowers in the spring to , • '� ` well as food for nectar P g provide color as some of the moths and butterflies that utilize li hummingbirds and laze the valley.• a n';: ,`; Other species of trees and shrubs were selected because of their growth characteristics (•-•e. , maximum height, branch density) and for their wildlife habitat value. Since the area is small and in close relationship to formal landscaping ,P 9 ,consideration was given to developing some type of a blend between the two systems. Low ,Flow Channel : r ` The low flow channel includes all of the designed low flow channel with the additional 2 1/2 to 1 slope buffer along }"� , ' both sides of the channel and of the over flow channels built into the system. The low flow channel will be planted with a mix of plugs, live plants, and seed. The mix will include bigheaded rush ( Scirpus macroca ) effusus) , spikerush ( Eleocharis , softrush (Juncos palustris) , three -square `bulrush (Scirpus americanus) , slough sedge g g (Carex obnupta) ,and dagger-leaf rush (Juncus ensifolius) .

The JD White T { '•_• Company, Inc.was contracted to delineate this wetland to the extent that it may come under the regulatory jurisdiction of federal, state, or local regulatory agencies. At the client's s lJ; ;; request this report constitutes a wetland delineation of only one wetland on the property, • The balance of the site was not examined for the presence of wetlands. LOCATION r { • ,: The subject property is located in Section 64, T,2S., R,1E., Willamette Meridian, Clackamas ' County, Oregon. The site is immediately north of Kruse Way and just west of Carman Drive (Figure 1). t I t v '' METHODS "Y ` The Unified Federal Method (UFM) (Federal Interagency Committee for Wetland Delineation [FICWD], 1989) and the 1987 U.S. Army Corps of Engineers criteria for determining wetland boundaries(COE Technical Report Y-87-1,Environmental Laboratory, 1987) were used for technical guidance when determining wetland boundaries on this ` property, The COE used the UFM criteria for determining wetland boundaries from 1989 until August 17, 1991. Since that time, however, the US Army Corps of Engineers (COE) has reverted to the 1987 COE wetland determination method. The Oregon Division of • 0 State Lands has indicated that it will continue the use the 1989 UFM. Because of this, a , ' wetland determination was made using each of these methods. Differences in wetland extent as determined under each method are discussed later in this report. • ;• ` Applying the 1989 UFM method,under normal circumstances, an area is defined as wetland / if there is a simultaneous occurrence of wetland hydrology, wetland (hydric) soils, and a dominance of hydrophytic vegetation. The UFM provides a somewhat different approach for sites such as this which have been disturbed. ``Disturbed sites are areas where "field * indicators of one or more of the three wetland identification criteria are obliterated or not present due to recent change" (FICWD, ��� 1989, p, 50). Under these procedures, disturbed ��vegetation communities are documented and considered, but the final wetland/non-wetland determination relies principally on hydrology and soils indicators, Historic clearing and land leveling for agricultural use has substantially altered the natural vegetation on this property. Along the delineated wetland boundary, recen. vegetation ' .J,.• disturbance (within the past five years) appears to be due to possible grazing by cattle or it. mowing. For this reason, procedures for delineating disturbed area wetlands were followed in this determination for areas outside of the drainage ditch, 1 1.F,, t , ,1 • 1 . • A variety of standard references were consulted for this determination. using the Washington County soil survey(Green, 1982;Figure 3) a U.S.S Soilils were evaluated • ' Service (SCS) hydric soils lists (U.S, Soil Conservation Service, 1991 .

The eastern end of vv ` I's• this strip widens toward the north and is part of a larger wetland area just off the property to the east. Two small wetland lobes extend north from the ditch (see Figure 3 gu .) Hydrology " ' Water is the critical, forcing factor in wetland.formation. For purposes of delineating , •,," wetlands, an area is considered to possess wetland hydrology if the soil is inundated or saturated for at least a week or more during the growing season in an average rainfall year (FICWD, 1989). In this area, the growing season is defined as the first of March through the end of October (SCS, 1987 . In poorlyand very q ) poorly drained areas, continuous soil saturation must be maintained within at least 18 inches of the surface for a week or more during the growing season in order to meet the wetland hydrology criterion. ..J The hydrology in the southern section of this property has been altered through the installation of drainage ditches. The natural surface water flow across the property was • through several shallow swales. These swales have been severed at their upper ends and the water diverted into a ditch located east of the ..t ', property. Some of the water for wetlands on this site appears to be supplied by local surface runoff. The primary source of water during the growing season, however, is a series of small springs and seeps to the northeast, P This water has been collected and diverted into a southward flowing ditch to the east of the property. This ditch then turns west and flows along the • n, property's south boundary Approximately one-third of the way across the southern edge of the property, the flow through this ditch is diverted through a culvert under Kruse Way. Water was still flowing in this ditch at the end of September, 1991, followingan extended dry period in the region. ' r Y { Local runoff from the western side of the property flows into the ditch west of the culvert, a• This part of the ditch is almost level but is slightly higher in its central section, Water, therefore, flows east in the east half of the ditch (en:enng the culvert under Kruse Way) and west in the west half (draininginto a culvert just east of small detention pond at the west end of the property), • `.The western part of the ditch receives very little water and only during periods of local precipitation. Because the ditch is almost level, water ponds in small depressions within the ditch forming small wetland areas: , 3 . �a % 44 ♦.w r T•._ �i. �k y, r .r .i r } .7 7 7 r , r 1 `a r , Y ♦ , `.; The two small wetland lobes extending northward from the ditch (see Figure 3) and the wetland area in the southeast corner of the property which extends between T1P1 and T1P2, exhibit clear changes in vegetation "greenness" based on persistent moisture in the soil. Soils in the "brown" areas were dry to 20 inches. Soils in the "green" areas, however, were damp near the surface and near saturation within 20 inches of the surface, PP This wetland delineation was conducted at the end of September following an extended dry period. Because of this, soil saturation was not present in all areas where the soil would *4,' `'' have been saturated earlier in the growing season. Indications of saturation including the ' • presence of hydric soils, signs of localized ponding, and deep tracks in dried mud, together ` with soil still damp at 10 inches and near saturation at 20 inches at the end of September, provide convincing evidence that the hydrology criterion is met in these areas. • Soils .7. h, '' Wetlands have hydric soils which are soils that are saturated, flooded or ponded long enough (usually considered to be a week or more) during the growing season to develop anaerobic conditions in their upper part (FCIWD, 1989). Typical field ln:iicators of hydric soils are the presence of thick organic layers, or in the case of predominantly mineral soils such as are found on this site, low chroma matrix (gray color) and bright mottling. The SCS lists soils known to meet the hydric criteria in their national hydric soils list (Misc. I :\':' J ` publication 1491, 1991). Soils within the study area are mapped by the SCS as I-Iuherly silt loam and Cove silty clay loam (Figure 2). Both are listed in the SCS national soils list as hydric. These soils are deep, poorly drained soils with low permeability. They are subject to the development of `A ` tillage pans from compaction by animals or farm equipment. Soils at the site appear to have ... : .' { such a pan located at a depth of 12 to 20". This pan seals the soil so surface water can not pass through into the groundwater system. This "perched" water remains well into the growing season exacerbating soil saturation near the surface. ' Vegetation • The U.S.Fish and Wildlife Service (Reed, 1988) has classified wetland vegetation according to its frequency of occurrence in wetlands. Plant species that occur in wetlands greater than 99 percent of the time are termed obligate (OBL) species. Those plants generally found in �,: wetlands two-thirds to 99 percent of the time are classified as facultative wetland (FACW) plants. Species occurring in wetland about half of the time are termed facultative (FAC) plants. Under normal circumstances, an area is considered to have hydrophytic vegetation when more than 50 percent of the dominant species, from all plant strata, are classified as OBL, FACW or FAC (FICWD, 1989). Plants listed as FACU (facultative upland),NL(not ,.,,,, listed in Reedl 983)o r NI (no indicator) are considered nonwetland plants for the purposes a * *, of wetland d ' t� 11 e , ., rc, t 4 • 1 .. f `c r' Y , 1 I.T. k'i Native vegetation,which probably consisted of Oregon ash,willows, sedges, and wet-adapted `.,•. grasses, has been completely cleared from P P Y this site. Currently the property is planted with�. pasture and hay species typical for the region. k Except in the southeast corner of the property, the steep sides of the drainage ditch exhibit a sharp transition from wetland species at the bottom to upland species near the top. East of the culvert under Kruse Way, the wetland area along the sides of the drainage ditch is dominated by FACW species such as un u � G s effusus and Alooecunr5 prat nsil. Also • common in this area is Ranunculus repens (FACW) and Burnex cLlspiis (FACW). The bottom of the ditch is dominated by wetland obligates such as Tvoh latafal�a, Veronica (FACW), and Carex obnupta. West of the culvert only the bottom of the ditch contain wetland species. Juncus effusus ( 'W), Alopecurus Prater:'is (FACW), Ranunculus rep, n (FACW) and Rumex crispus (FACW) dominate this area. ,< The wetland at the eastern end of the ditch extends northward (Figure 3) into a shallow swale. This area historically was the drainage course for water now diverted into the .., = drainage ditch. Enough subsurface water, however, still flows through this area to maintain saturated COD'' bons well into the growing season. Vegetation in this area is disturbed by agricultura.1 operations and mowing. The area is dominated by typical grasses and weedy forbs found in wet pastures in the region. 1 The better drained (upland) areas were dominated by typical pasture grasses such as tall p bent fescue (Festuca arundinacea, FACU), orchardgrass (D ctvli. glnmerg g, FACU), and gr (Agrostis tenui s, NL). Sweet vernal grass u.� , FACU),Kentucky bluegrass (Fos pratensis, FACU), and velvetgrass um �cinTat,,f„ ,.. ( Io_cus Lana ,s, FAC) were - 'n �` common. Other weeds and forbs typical of pastures and hayfields in this area were also present. These included Canada thistle (Cirsium arvence FACU), sheep sorrel (Rumex `' acetosella, FACU), dandelion (Taraxacurn gf inalg., FACU), tall buttercup (Ranunculus mit S - , and clover (Trifolium spp., FACU). r I. DELINEATION SUMMARY National Wetlands Inventory mapping (Figure 2) does not identify wetlands within the subject property, Field observations, however, established a linear strip of wetland within (and bordering) a drainage ditch along the south property boundary, Wetland was limited L•.. to the bottom (SP-1) and sides of the ditch except for two small wet lobes extending northward into the property and a small wet area adjacent to and north of the east end of the ditch (T1-P1 and T1-P2), The wetland area within the ditch is located on a steep topographic gradient. The transformation from "clearly wetland" to "clearly upland" occurs rapidly along this slope. • S ,y i • iy . . 6^ ® t • The total wetland area was 0.27 acres using 1989 UFM wetland delineation acres using the 1987 COE criteria. Although much of the criteria and ay culvert does not meet 1987 COE wetland criteria for vegetation, the entire ireof tdr Kruse Way was considered wetland because it is probablyr ' Y under federal jurisdiction as waters of theUnited States. The entire ditch is wetland under 1989 UFM criteria.r • �: Relationship to 1987 COE Methods 9 Application of the 1987 and 1989 wetland delineation methods on this roe different wetland boundaries as indicated in Figure 3. One difference property results in 1987 wetland delineation manual and the 1989 UFM lies in the method the for determining the presence of hydrophytic vegetation. The UFM allows, used far • , ': conditions, for the assumptiun of hydrophytic vegetation provided under disturbed ' hydrology are present.

It is important to note that these improvements will not be warranted upon completion of this development, le 4 but rather will be necessary at some time in the future as traffic Volumes within the study area begin to approach the levels identified in the year 2000 forecasts. • There are several distinct advantages associated with providing direct access to Kruse Way via a driveway located midway along the property frontage. Further,given that the access would serve relatively low volumes and be limited to right-turn movements,the driveway ` r will not significantly affect operations on Kruse Way. Considering these factors,serious .' consideration should be given to providing direct access to Kruse Way. ; ' SCOPE OF THE ANALYSIS0 •• In conjunction with the approval process for the Westlake P.U.D. a detailed traffic impact analysis was } conducted that considered both the local and area-wide traffic related impacts of the entire P.U.D. through the year 2000. That analysis was conducted in 1979, and was approved as a part of the development •" application at that time. Therefore,the proposed development's traffic impact has already been accounted .`• ' . for as part of a broader area-wide study. Accordingly,this analysis attempts to address some of the more microscopic issues specific to the current development plans that were not addressed in the previous traffic ` +, analysis. The specific traffic-related issues discussed in this letter include: ' • • An update of existing traffic conditions in the project area within the immediate vicinity of the site. • • Trip characteristic estimates for the proposed development. , , • Site access location and operations under two access alternatives upon completion of the proposed development. • A review of the previous traffic study's projected year 2000 conditions at key off-site intersections within tth, immediate vicinity of the site, . f ' ' , Mr. Nawzad Othman . October 18, 1991 Page 3 • Pedestrian circulation issues. The following sections address each of these issues: EXISTING CONDITIONS Manual turning movement traffic counts were conducted over the course of three weekdays in August 1991, by Kittelson and Associates, Inc.,to determine the morning and evening peak hour traffic volumes at the key intersections within the study area. Based on the result of these counts,the a.m, and p.m,peak hours were generally found to occur from 7:30-8:30 a.m. and 4:30-5:30 p.m., respectively. The observed ' arm, and p.m. peak hour traffic volumes are illustrated in Figure 2, EXISTING LEVELS OF SERVICE To assess the traffic conditions at key intersections in the study area, capacity analyses were conducted ti using the analytical procedures described in the 1985 Highway Capacity Manual (Reference 1). These procedures allow the analyst to examine the roadway's and/or intersection's features and then determine • the traffic that can be accommodated for each movement. These values are then compared to the actual 4 ,• :s x traffic demand. Based on these results, a letter grade Level of Service is derived for each movement that reflects how much traffic congestion will result. Level of Service (LOS) is A concept developed by the ; transportation profession to quantify the degree of comfort(including such elements as travel time,number of stops, total amount of stopped delay, and impediments caused by other vehicles) afforded to drivers as they travel through an intersection or roadway segment. Its letter grades range from "A",indicating that Y vehicles will experience little,if any delay,to"F",which indicates significant traffic congestion and driver'" g �.. . delay. Fcr signalized intersections,LOS defines the quality of the traffic flow, but does not necessarily describe the overall design adequacy of the intersection to accommodate the traffic volumes being analyzed. As an example,a good LOS can be achieved even when the volume/capacity ratio for the intersection exceeds 1.0. Similarly,there are conditions under which a poor LOS is achieved even though the volume/capacity • y ratio for the intersection is well below 1.0. Therefore,all signalized intersection summary tables contained in this report provide both the calculated LOS and the calculated volume/capacity ratio for each intersection. In this way, the reader is provided with a complete description of the expected operation conditions for each signalized intersection that is analyzed. The typical Level of Service standard for - jurisdictions within the Portland Metropolitan Area is that Level of Service "D" or better be maintained at signalized intersections. Clackamas County and the City of Lake Oswego alos endorse these standards, .. r, t p. Mr. Nawzad Otnman • October 18, 1991 ` Page 4 For unsi alized intersections, , LOS is defined differently than for signalized intersections in that it is based upon the concept of"Reserve Capacity" + (i.e., that portion of available hourly capacity that is not used), The reserve capacity concept applies only to an individual traffic movement or to shared lane movements. Once the capacity of all the individual movements has been calculated and their LOS and expected delays determined, an overall evaluation of the intersection can be made. Normally, the" ' movement having the worst LOS defines the overall evaluation,but this may be tempered by engineering judgement. Past experience with the unsignalized analysis • y procedure indicates that this methodology is very conservative in that it tends to overestimate the magnitude of an ' t t. Therefore, the results of any unsignalized intersection analysis should with be reviewedthat might exist this thought in • ` mind. The typical Level of Service standard for jurisdictions within the Portland Metropolitan Area is that Level of Service"E"or better be maintained at unsignalized intersections. Again,bothClackamas Coun . ty and the City of Lake Oswego endorse this standard. •Y '•i All LOS analyses described in this report were performed in accordance with the procedures described '' { above. Copies of the analysis forms are contained in project files and are available for review upon request. In order to assure that the analysis is based upon worst case conditions, the flow rates for the :Ar.1 r peak 15 minute period during the morning and evening peak hours were used in the evaluation of all intersection levels of service. Thus, the analysis reflects traffic flow conditions that are only likely to• occur during the peak 15 minute periods of the morning and evening .e$F� n' . •S:rTherefore, for the remainder of each weekday and throughout the weekends, traffic conditions within the s t study impact area are likely to be better than that described in this report. the Table 1 summarizes the results of the existing intersection LOS calculations for each of the key .r intersections within the study area. As this table indicates, the key signalized and unsignalized intersections within the study area are currently operating at an acceptable LOS during weekday morning and evening peak hour conditions. SITE GENERATED TRAFFIC VOLUMES • Estimates of total morning and evening peak hour driveway volumes were calculated for buildout of the development on the basis of empirical observations at similar developments located throughout the United States. These empirical observations are summarized in a standard reference manual published by the •' Institute of Transportation Engineers (ITE) (Reference 2). Table 2 illustrates the trip generation results. As shown in the table, the proposed development is 1 , anticipated to generate an estimated 160 average weekday A.M.peak hour trips,and 205 average weekday P.M. peak hour trips. • ;, ' q 111 A } • • Mr. Nawzad Othman October 18, 1991 Page 5 DESCRIPTION OF ACCESS ALTERNATIVES 3 f'.

The general • directional distribution is shown in Figure 3 for the proposed development. Consistent with what would • "• be expected, project-generated traffic is expected to distribute itself predominantly to the cast and west of the site via Kruse Way. Based on the estimated trip distribution pattern,the estimated number of trips for the project were assigned 1. to the surrounding road system tinder each access alternative. Figures 4 and 5 illustrate the results of this effort for the A.M. and P.M. peak hours for each of the access alternatives. 1992 OPERATION OF SITE DRIVEWAYS KEY OFF-SITE INTERSECTIONS •; �` The projected site-generated traffic volumes identified in Figures 4 and 5 were added to existing traffic volumes identified in Figure 2 to obtain an estimate total traffic volumes at the key off-site intersections upon completion of the development. Figures 6 and 7 display the results of this effort for each of the •,, access alternatives. • Based on the projected 1992 traffic volumes identified in Figures 6 and 7,LOS analyses were conducted at the site driveways and each of the key off-site intersections, Table 3 simnmarizes the results of the 1 intersection LOS calculations for each of the access alternatives. As shown in the table, under either of ' { the access alternatives,the key intersections and site driveways are anticipated to operate within acceptable ' LOS limits. Further, under either of the access alternatives, the estimated project related traffic will not • significantly affect the quality of traffic flow on the any of the roadways within the immediate vicinity • of the site. . liri' 410 . . ,.. . , . ... . • , .. it • Mr. Nawzad Othman October 18, 1991 ti Page 7 YEAR 2000 CONDITIONS As mentioned previously, a traffic impact analysis (Report on Tr Development, Reference 3) was conducted as part of the Westlake Plannedc a UnieDevelopment.ake pd Unit This analysis evaluated the off-site traffic related impacts of not only this development, but the entire Westlake Planned Unit Development through the year 2000. A review of the analysis methodology, Y results and conclusions of that study was conducted as part of this analysis. Based on the results of that review, Kittelson & Associates, Inc. concurs with the major findings and conclusions of the previous study with the following exceptions: • • The Westlake Drive/Kruse Way intersection will require the addition of a right-turn lane on the westbound approach to the intersection, • Both the northbound and southbound approaches to th' Carman Drive/Kruse Way • intersection will need to be widened and improved to allow for the provision of separate left-turn, through and right-turn lanes. It is important to note that these improvements will not be warranted upon completion of this development, but rather will be necessary at some time in the future as traffic volumes within the study area begin to approach the levels identified in the year 2000 forecasts ver, enee for these improvements are not the result of additional traffic from this development proposal. Rather,the need for these additional improvements reflects markedly improved analysis techniques since the original 1979 study. 1 COMPARISON OF ACCESS ALTERNATIVES As discussed previously, adequate intersection operations at the site driveways and key off-site intersections will be maintained upon completion of the proposed development under either of the • proposed access alternatives. However, there are a number of advantages associated with providing a a' limited access driveway on Kruse Way: • The Kruse Way Alternative results in a projected 50 percent reduction in the number of , " site-generated trips on Westlake Drive, Parkview Drive, and Carman Drive during the combined morning and evening peak hours. This reduction would help to preserve more • of the capacity of these three roadways. • The Kruse Way Alternative will improve internal circulation because it results in a more , equal distribution of north-south traffic within the development. In the absence of a direct connection to Kruse Way, all of the internal traffic is required to enter and exit the site via Parkview Drive. The Kruse Way Alternative provides for better emergency vehicle access in that access is provided via two roadways as opposed to one, • The Kruse Way Alternative is preferred from a pedestrian and bicycle standpoint in that it results in a reduction in vehicular trips on the internal street system within the Westlake % P.U.D, c' i • 1 1* yl, r Mr. Nawzad Othman October 18, 1991 Page 8 a r• TABLE 3 PEAK HOUR LOS ESTIMATED 1992 TRAFFIC VOLUMES SIGNALIZED N SY NALIZED p Time Intersection Period Reserve . :.e i Delay LOS V/C Capacity LOS • Kruse Way/Westlake Parkview Only Alternative AM 0.56 23.1 C PM 0.66 28.0 D Kruse Way Alternative AM 0.49 22.3 C •_____, P.M 0.64 25.9 D Kruse Way/Carman Parkview Only Alternative AM 0.52 14.7 B PM 0.70 23.0 C Kruse Way Alternative AM 0.52 14.7 B PM 0.72 23.2 C Westlake/Parkview • Parkview Only Alternative AM d PM • 269 C ;' Kruse Way Alternative 227 C ,�.

PEDESTRIAN SAFETY ISSUES A special investigation was conducted to determine the existing and future safety of pedestrian circulation ' in the Westlake area. Pedestrian traffic on streets in the area was observed . during the critical a.m. and p.m. peak hours. Pedestrian movements were observed crossing the Westlake Drive and Ca ,.. :' .. Carman ?. intersections,primarily on the north side of Kruse Way, This includes a large number of joggers as bicyclists. Pedestrian movements across Westlake and Parkview n Jgg as well t, to be relatively minimal. ° of Kruse Way were observed r {.: Special consideration was given to the safety of pedestrian crossing of Westlake Drive and • in the vicinity of their intersection, especially eParkview Drive d to the buildout of the subject multi-family development ofAccordinglyprojectea estimates traffic growth do these streetso due were conducted. These projections indicate that pedestrian volumes across Parkvieweand strian movements well within acceptable limits for uncontrolled intersections,given projected vehicular trafficWestlake are the availability of sight distance on these streets. Thus, special pedestrian controls (i.e.vol umes and • • • pedestrian actuated traffic signals, pedestrian beacons, etc.) would not be wanted at these locations. ts Moreover, the major pedestrian movements would continue to be facilitated by crosswalks and pedestrian signals at the major intersections with Kruse Way, The provision of sidewalks on these :. . . ,* streets,as adjacent properties develop, will ensure safe and convenient pedestrian circulation.

"A" St. ' Lake Oswego, OR 97035 SUBJECT: Westlake Improvement Requirements for the Kruse Way Access : a Dear Mr, Baker: ': Kittelson & Associates, Inc. has examined the functional and geometric requirements of the proposed right-in/right-out only access to Kruse Way for the Westlake Apartments. The proposed access is approximately 480 feet west of Carman Drive. As discussed in the Traffic Impact Report ....ii for the Westlake Apartments (Kittelson, October 18, 1991), this driveway would serve as a "relief valve" for site-generated traffic that would otherwise use Parkview Drive. 4 r• The proposed driveway should meet the following design standards: 1) 15:1 Taper over 195 feet to reach a 13-foot depth ' 2) 100-foot deceleration lane J'' 3) 30-foot inside curb radius According to discussions with Jeff Goodling of Tri-Met, the proximity of this driveway in combination with the fact that it will not be signalized indicates that it would not be a good location for a transit stop. The nearest bus stop along Kruse Way, to serve Tri-Met line #38, is located at Carman Drive. A potential far-side bus pullout at the proposed driveway would be approximately 650-700 feet from the existing stop at Carman Drive. This proximity would render a potential stop at this location redundant and therefore not necessary. The analysis that Kittelson & Associates has .4. conducted confirms Tri-Met's recommendations that a transit stop in this location is not indicated. . 4 ` It is further recommended that pedestrian paths be provided to allow as direct as possible access to the existing transit facilities. Tri-Met also agrees with this recommendation. d Sincerely, ,;t���,D ROF a . '-b(4414` cf�"`a'wtia0I N @4 Sc, _,. JD% / ti �� ,fiR//'��od, u Daniel , Seeman , Katsion, P.E.

Based on this analysis, using revised traffic volumes from the Lake Oswego traffic forecasting • . .: :', model, Kruse Way will operate at LOS "D" or better in the p.m. „ peak hour with improvements to the intersections with Westlake d Drive and Carman Drive. Figure 1 presents the traffic volumes developed from the transportation model. • Table presents the results of analyzing these traffic volumes J• on existing intersection lane configurations and signal timings, as well as under improved intersection configurations. This table indicates that while the two intersections in question will not operate at an acceptable level of service when loaded with 2010 traffic volumes, they would meet the LOS standard of "D" if some intersection improvements were performed. « ° , .f At the intersection of Kruse Way/Westlake Drive, a westbound exclusive right turn lane on Kruse Way will provide sufficient capacity to achieve LOS "D" . Based on field observations of the • intersection, there appear to be no physical constraints to 'r, providing this improvement. At the intersection of Kruse Way/Carman Drive, the existing • shared through-left turn lanes on the northbound and southbound approaches should be replaced with an exclusive left turn lane, a through lane, and an exclusive right turn lane. Field observation of this intersection indicate that this ' ,' proposed lane n' ",configuration can be facilitated within existing right-of-way, 4 ` 41) although this should be confirmed. : r EXHIBIT • 902 Abernethy Road • Oregon City, OR 97045.1100 • (503) 855-8521 • FAX 650 , I a • Overall, the analysis indicates that while 2010 volumes cannot be satisfactorily carried by the existingklaneffic configurations of these Kruse Way intersections, improvements to the intersections will achieve LOS "D" or better without widening Kruse Way to a six-lane highway. f A ,, If you have any questions ,'�' Please give me a call at 655-8521.

Tacoma, Washington 98467 • Attn: Mr. George Berry ` �`' Re: Preliminary Subsurface Investigation, -".� Proposed Apartment Complex, Parkview Drive, (Westlake) , Lake Oswego, Oregon a . Dear Mr. Berry: A new apartment complex is proposed for construction on about a 20.8-acre site located off Parkview Drive,• just to the north of Kruse Way in Lake Oswego, Oregon. The Site Plan, F g , Figure pure 1, .• shows the approximate location of the site. We have completed a preliminary subsurface investigation for the proposed apart- meet project.p 7 Presented in this letter report are the results of our field explorations, laboratory testing, and office • , . `. studies. Conclusions and recommendations concerning founda- tions, earthwork, subdrainage systems, and design of the pave- ments for the access roads and parking lots will be provided in our final foundation investigation report. The Site Plan, Fi gure 1, shows the location and configuration of the new buildings on the site. Ground contours obtained s . from a drawing by Berry & Berry Associates, dated January 31, 1.989, are also shown. The site, which is brush and grass covered,, has nearly 35 feet of relief, sloping from northeast to sot thwest. nriL1: 110E ''.§ E . . ..

The buildings will be two to three stories, • Geology Published geologic literature (Bulletin 99) as well as our • nearby project experience,7 indicate that the site is probably �6y underlain at shallow depths by silts of the Portland Hill Silt �J formation, in turn, underlain by residual soils of the Boring ,' , .r : ; Lava formation. Boulders maybe " � = s present at depth that may • pose excavation and disposal problems. ~.,.: , Field Explorations .1,'," ;). Five test pits were made on the site at the locations shown � 5, in Figure 1 in order to obtain the general subsurface informa- tion. Test pits were excavated to depth 10 to 12 feet. The 0 , ., . `,. I test pits, designated TP-1 through TP-5, were excavated on • .wr April 4, 1989, using a backhoe provided by a local contractor, A representative from our firm located the general areas for the excavations and maintained detailed descriptive soil logs '" of the e xplorations. i•` Representative `disturbed samples were taken at selected depths in the test pits for classification and for physical testing. The disturbed samples were sealed inglass p jars. In situ i -w undrained shear strengths of the soils exposed in the side- ,'; walls of the test pits were evaluated using a Torvane shear device and/or a y. `. / pocket penetrometer. All the samples were returned to our laboratory for check classification and lab- oratory testing. 2 • r r •• . „i 4 % The logs of the test pits are presented in Figures 2 through 1l it r �i log presents a 6. .each r general description of the types of • soils encountered and the depths where the soils changed in �' ' composition and/or characteristics, although the changes may be gradual. Further to the right, the number, depth, and types of samples that were obtained are shown, as well as the in situ shear strength estimates, and natural moisture (water) , r' contents. Also, shown are locations of water seeps and/or ground water levels measured in all the test pats. The ground water' levels and seeps are only for the date shown and they may vary from time to time. tit t Laboratory Tests t All the samples were returned to our laboratory for further h' ! examination, and check classification. During classification, .certain physical characteristics of each sample were noted; ,• y'1 A 1 for example, the color, the degree of plasticity, unusual �, ,� odors, and if the sample was dry, moist, wet or saturated. • The natural moisture (water) content of each sample was meas- _ r\ tired. The moisture content is tr s ek r ratio of the weight of water to dry weight of soil, expressed ,_ as a percentage. The ' ` 1 values of moisture content are plotted on the logs of the test =" pits, Figures 2 through 6. A. ° Discussion of Subsurface Conditions d The field explorations disclosed that relatively uniform sub- surface conditions exist beneath the site of the proposed apartment complex. The subsurface materials encountered co sisted primarily of silt with varying ry g percentages of clay and fine sand. . The top 12 to ].4 inches of each test pit contains a topsoil unit. The topsoil consists primarily of brown silt .. • • g i' s: with trace to some sand and clay, which is moist to wet and } K'aY contains numerous organics. Underlying the topsoil, almost similar soil materials were observed, consisting of medium t stiff to stiff brown silt with trace to some clay and fine . sand. r a`An exception, however, is the 2.2 feet of plastic gray silty clay that was observed underlying the topsoil in test pit TP-5. At depths Y ". between about 5 and 12 feet, the silt grades to • probable residual soils of the Boring Lava formation, clas- sified as light brown, green, mottled orange, fine sandy silt • to silty sand. The unit becomes gray at depth. No boulders u ; ',. were exposed in our excavations, but they may exist at depth and be encountered in any utility trenches. ;. e 1 , Ground water seepage, in some cases abundant seepage, was observed in all the test pits at depths 2.2 to 2.6 feet and below. Based upon our experience, we anticipate that the • ground water table will fluctuate with the seasons, rising in t the winter and fallingthe summer. The actual ma Y in finitude y of the fluctuation is unknown, but it may be in the order of li ia . F few feet. Hence, in the wet, winter seasons, the ground water table may be at, or very close to the ground surface. Conclusions and Recommendations-Poundatjon/Earthwork (Prelim- inary) General. The field explorations made as part of this prelim- . .' inary investigation disclosed generally uniform subsurface conditions. A relatively thick topsoil, or organic soil was ,.' observed. However, the underlying soil units appear to be • relatively firm, therefore, buildings, in our opinion, may be G .t founded on spread footings. Other considerations for the ~ r. '' development of the site are discussed in the following para- graphs. a 4 y. • a • t - �. ..n, J iA! 1 ! r J ;4 1 '. 4•• JI ,4; r ' •r. The sites of buildings,g parking lots and access drives should be stripped and grubbed so as to remove all grass, roots, and organic soil. At the • present time we recommend that the top t 12 to 14 inches of topsoil be removed. Locally, organic zones or large roots may require deeper stripping ,' and grubbing. Any plastic clays, similar to that which were observed in test pit t n e TP-5, may cause excessive shrink/swell volume change if the moisture content is allowed to dry below the plastic limit. As a precaution, we recommend, if such "plastic clays are ob- f • fJ ` served within the limits of any apartment unit, that they be ' overexcavated and replaced with structural fill. • Based upon the ground contour elevations shown in Figure 1, ` ' most likely some cuts and fills will be required in order to establish access road and building grades. Onsite soils may be used in structural fills, if the earthwork is accomplished ' during the drier construction season. Recommendation for the ` 0 fill material and the percent compaction will be discussed in our final foundation investigation report. J f The depth to ground water seepage at the time of the explora- 0 tions was very shallow. Therefore, a subdrainage system should be installed behind embedded walls and beneath concrete slab-on- grade floors in order to reduce the risk of ground water entering the buildings as well as to reduce the risk of adverse hydrostatic pressures. This will be particularly important where buildings are founded in excavations. Limitations The scope of the preliminary investigation g presented herein is limited to an investigation of the subsurface conditions M' , for suitably founding the proposed thirty-three apartment `y 5 4 • : •e. to t.. • ". -. ,t • , - 7` f ♦" e A ,rr 1 • • • _ buildings, and associated parking lots and the access drives.

Less than 15% of total phosphorus was removed at the Stedwick site over the . , . . long-term; whereas, initial results at the London Commons site indicated much higher average (70%) total phosphorus removal (OWML, 1986a) . However, it is very likely that the long-term total phosphorus removal at the site is much lower, since verylow removal(or even negative) rates were reported for ',4.., • larger storms: Resuspension of total phosphorus was cited as the likely + ' 4. cause. NITROGEN In the OWML (1983) settling column experiments, the upper limit on nitrogen removal achieved after 48 hours of detention was about 40%: Again, this is due to the predominance of soluble forms of nitrogen that comprise %+ about 70-80% of the total nitrogen found in the Washington, D.C. area urban ' runoff (NVPDC, 1983). Field studies at the Stedwick extended detention pond ' ` suggested a long-term total nitrogen removal' rate o.f about 25%, which re,^w compares well with the lab studies (Figure 3.7). Almost all of the particulate nitrogen settled out from the pond, but only limited settling of soluble nitrogen forms was reported. A higher average storm removal of total nitrogen was reported (52%) at the London Commons site (OWML, 1986a), although the long-term removal rates may not be as high. 5 i• Figure 3,6: Removal Rate vs. Detention Time For Selected Pollutants .1' + d .w ,..;r I 00 r ..

' Privaaxy concern - increased traffic flow: I„ Single conce rn ern is that 3-bedrooml2 bath units will mean more traffic. Neighbors an concerned about the quality of Vie, traffic flow, noise factors due to traffic. Heavy traffic on Parkview as opposed to Carmen Drive. Would like to see another access on Kruse Way (right in/right out) to alleviate heavytraffic. y (right dissipate truffle f Most dispute would be eliminated if we could p lc with another access road. (Erin &Bob) Neighbors have two primary concerns with the currently proposed neighborhood commercial project. Traffic and design. Regarding design, the project will heavily affect southwesterly flow of traffic. City has not had opportunity to review the traffic Traffic studies were done one decade ago and something has gone amiss,flow on Westlake c of m currentlymuch volume is greater than the original projections. In talkingto Jerry findings are in process. Hearingwill be August r+y'Baker eveltraffic 19. Ekert and Moody are the developers, Nib Bunick - owner (Erin) r City of Lake Oswego and City Council had given their assurance that a comprehensive study would be done when the Dominion project was proposed. Unless the City follows through r ` and does this- OT.AKIGSL will be caught by precedent. City promised us a traffic study, we don't feel this project should be approved without one. (Bob) Distribution is currently high because some of the street improvements have not been done, for example Parkview to Carman. Actually though the responsibility of traffic is with the • City, My understanding is that the City has starter; this study and has been working with _ . 1 the County but it is not yet completed. As far as access points, they are dictated byco ut 1 �„ ' order, city, state, etc. Kruse Way was built by Clackamas County, received state funing,and access points were set. Trip generations have not changed. Zoning/land uses have not changed. Butke used the comprehensive plan to complete his study. (Nawzad) More than density is a factor in traffic studies, other factors include: number of people pper r house, si.v of houses (Westlake houses are typically large). (Erin) p p Per Officer Mays, apparently McDaniel will be closed because it is actually a (Erin) private street? S • ', ,i5-�0',`. • In summary, we will talk to the City and find out mechanism to take care of traffic r ' • concerns. (David) Other miscellaneous questions and concerns What is your market target g young families or singles? Mob) Targeting is unreliable - there are always surprises. y rp Thin project covers the spectrum. One to three bedrooms. Current scope includes 25% one bedroom; 25% one bedroom plus; 25% + F , 4 ti ' 1 pre]iminnry Neighborhood Meeting- Westlake apartment project August 5, 1991 Page S l ;r two bedroom, two bath; 25% 3 bedroom, two bath. Expect a big percentage of empty nesters, divorced people, young people saving up for their first home, and young families. Rents will range from $550 to $695 for one bedroom and $1,000 and up for 3 bedroom. (David/Ralph) ;;, Anent you concerned about vacancy rates? (Bob) Market is firming, should stabilize by fall. In one year we expect that apartments vill again be full. When this project is done, it should be a seller's market. • • • I. • • • • • • • • • y 1 , IY 1 Preliminary Neighborhood Meeting- Westlake apartment project • August 5, 1991 ..... .. ..: Page 40 . ,:.. —es,` Is there a niche for another Vera 1: type of project- what about town homes? (Bob) First the current property owner, the Church, has specific requirements - mainly that this be a m/f project. Also townhomes are not doing well. Additionally, this is the last major '' ;' apartment site in Lake Oswego except for a site in Mountain Park, (Dave) Y . Design questions and concerns Design points by David: GSL has an agreement with the Church that the project is compatible with Westlake Meadows. Buildings will be simpler in construction and higher ,,A' in features. GSL typically spends more money than their competition on landscape g architecture, with the exception of The Quintet project. Please visit Sterling Pointe to see quality of GSL's project. Will use wood siding in attractive colors. Design issues, specifically parking- is their any way to reduce ugliness? (Bob) Some GSLprojects have garages to eliminate this problem. Find it important to extend b' ' neighborhood lines. Will orient buildings to neighborhood and open space. One of primary goals is to become a "welcome neighbor" not set apart. Will try to cluster buildings so a •'' renters are not looking into neighbors backyards. Creative plan with quad's, plaza's, project will be a benefit to the neighborhood. Simple design,gn, elegant, architecture will hang together, be coherent, keep to theme. Project planned for 700 cars, at 2 to 1 ratio, approximately 7 acres of parking, total project is 18 acres. We realize that parking on Parkview will be eliminated soon. (David/Steve) If you check out GSL's current projects you will see that they all have a different look and are designed for the site. GSL takes design very seriously. (Nawzad) As farparking unit as g- is their a good alternative to garages? (Bob) Y Garages are used primarily in 3-story buildings, and in more urban and higher density projects. (David) • Differences between previously proposed Dominion project and current OTAK/GSL project Dominion project - no order; chaotic; not a positive relationship to the neighbors; buildings lined up on perimeter; no focus; dominated by circulation; parking overwhelming, out of • scale, large buildings; lots of parts - no cohesion, .4. • 0 a a 4 ' + •per a I - •, ^'" ,, n_ t' A, y1 •j h GSL Westlake Apartment Project- Project No. 3371 A • Preliminary Neighborhood Meeting No. 2 -Wednesday, August 21, 1991 7.30 p.m. at ()TAX • Attending Neighbors: Bob Barton Home Phone: (503) 639-8382 Work Phone: (503) 323-9000 GSL: David Bell,Vice President • , OTAK Nawzad Othman Ralph Tehran Steve Routon Jill Jones y.9 Nawzad: We hive prepared two cite plans, one with a right in/right out access on , ,,t Kruse Way. Steve R.: Scheme 1, dated August 1, had only one access (Parkview). The buildings are clustered with lots of open space. 33 buildings total. . Scheme 2, current scheme, has fewer buildings - 31. From Parkview you can see little evidence of parking. Has a right in/right out access on Kruse• ' Way. Property edge is designed so all elements are one-story to blend into the residential neighborhood. There are a lot of landscape opportunities in the areas facing the neighborhood. Very aesthetic. Site looks very open and not at all cluttered. Nawzad: County has said if we can convince the City of an access, and if this access does not jeopardize Kruse Way, the County will go along with the City's decision. The City is placing the burden on OTAK. Approval will not happen until the DRB level. Bob: Thg right in/right out access will hopefully reduce the traffic flow. This should give you a chance against any opposition. Y FYI- the commercial site goes for rebuttal on September 4. In the August ' . 19th DR$ meeting, it was brought out that during the Dominion project's approval process, the City had agreed to do its own study to determine the traffic impact of the Dominion project and other projects. •' r If you can prod the City to do the study, this will save you tame and money. :' , Nawzad: We have already discussed this with the City.

Nawzad: In reality, the City may approve scheme 2 but without the access. Bob: What is overall traffic impact of this project? Access of Kruse Way should reduce any traffic problems.

PL,ly will not be in numbers but rather in where the units go and how they get there. I understand that the preference of the • neighborhood is no development at all, but this is the real world, If we , commit to this scheme, we need neighborhood and political support. Bob: I cannot commit for everyone - but would like to circulate the site plan among the traffic committee, and others, so they can review the design, traffic and wetlands issues they are concerned about. - Nawzad: Do you want OTAK to present it to others with you? • Bob: Erin would like to set up another meeting and involve more people . including the different groups concerned about traffic, wetlands and design issues.

Bob: What is your time frame? David: We are not expecting any guarantees. You, Bob, are more active in the neighborhood, more knowledgeable, and can transmit concerns. Site plan two will be difficult to pass, but with the neighbor's support we have a chance because of the City's desire to meet neighborhood demands. Bob: Right now I would say that Site one would receive 100 percent opposition. As far as Site plan two, the neighbors may say that if this has to happen, this one is the best. I would be very surprised if DRB dumps the access idea. ) David: After hearing the advise of experts, we feel confident abut this project. 7 • The only question is the timing, we could face lots of opposition and delays. i Bob: Carmen is at traffic level D.

Nawzad: Well, the economics of the project have to work. Steve: If this were designed with 30 units Iess, we wouldn't lose any "footprints". Bob: • From a marketing standpoint, the access will help you get through the process quicker, plus prospective tenants will notice the easy access when ,' looking at the units. Steve: The bottom line is that GSL would not do an access without the neighbors finking for it. • Bell: We were not even considering an access until after the input in the P last meeting. As far as a marketing selling point, surveys have shown that prospective tenants do not usually consider access points when apartment shopping. • Bob: An I mentioned, I cannot commit for the other neighbors.

Dear Hamid: (' % t In 1989 Scoles Associates, Inc, conducted a wetland delineation of the Westlake II site 4. (formerly Pointe South) as a subcontractor of IES Associates of Olympia, Washington, The following is a review of the Westlake II wetland values and their relationship to the "Essential Wetland" classification found in the City of Lake Oswego ordinance entitled r. "Wetlands" Section 4,035(1), Wetlands on the Westlake II site are very similar to and portions are an extension of the Westlake Meadows wetland system to the north. The east/west ditches draining the field and the north/south ditch along the west property line are less distinctive wetlands since • 0 they are incised and support limited emergent plants. The west property line ditch is the downgradient end of the Westlake Meadows west property line ditch that extends to Kruse , Way Ken Bierly from the Environmental Permits Section of the Division of State Lands stated in a letter to Mr. Humid Pishvaie dated August 3, 1989 that the wetlands found on the Westlake Meadows site to the north did not qualify as "Essential Wetlands", His statement ` was made after a thorough review of the City of Lake Oswego Ordinance Section 4,035(1), Overall, I concur with Mr. Bierly's comments, y I have followed Mr. Bierly's format, but made the necessary modifications to reflect the actual wetland values present on this site, a) Natural groundwater recharge: The wetlands on the property do not provide direct groundwater discharge recharge functions; the ditches merely convey surface runoff from the north or in the fields to the southwest corner (at Kruse Way). b) Storage: The wetlands on the site provide an extremely minor storage function as defined by the size of the ditches, The small size of the wetland areas make them of very minor value for flood storage. c) Turbidity reduction: Any time water runs through vegetated wetlands like those on the site, it will reduce the volume of suspended material in the water, This • . function will likely be hot significantly different from adjacent upland vegetated portions of the site, Since drainage is concentrated in the wetland area, greater turbidity reduction can occur in the wetland portion of the site. (This comment is verbatim of Mr. Bierly's letter,) 4; 461 1)14044.1,Ir'r)t 0, 1 ' Mr. Hamid Pishvaie January 9, 1992 ° 4 • City of Lake Oswego Page 2 d) Filtration of nutrients: Because the wetlands are areas of concentration of runoff • water and are fully vegetated, they will provide nutrient absorption value. The Y i limited area of wetland in relation to upland will minimize the value of this function. (This comment is verbatim of Mr. Bierly's letter,) e) Natural biological functions: Because of the small size, the wetlands on the site ; �I do not provide any significant or unique nesting, spawning, rearing habitat and • have extremely limited protective cover. The wetlands on the site may provide 7. habitat for amphibians, although significantly less than the Westlake Meadows site, due to the incised nature of the north/south ditch on the west property line. a The graminoid cover of the emergent wetlands is similar to the graminoid cover throughout the rest of the site. Bird species and others species that utilize the wetlands will likely not be different from their use of the upland portion of the• site, • f) Distinctive natural area: The area has not been designated as a distinctive natural area. ti • In summary, the relative value of the site's wetlands were historically destroyed when the native ground was cleared and converted to pasture land. Many of the typical wetland values no longer exist, although several would be "restored" in the mitigation plan designed f by OTAK, Inc.

Ron Weinman ' s (Clackamas -° ' "s County Transportation Planner) letter dated October 28th to "''' Jerry Baker concerning the future traffic impacts to the ' Kruse Way and Westlake Drive intersection . In Mr . Weinman ' s letter and in the Applicant ' s Request For Development Review Approval (G. S . L . Properties , Inc. and OTAK Architects , P .C. ) ti. n it is acknowledged that a westbound right turn lane will be required on Kruse Way at Westlake Drive . The Applicant ' s report states that the westbound right turn lane will be required to accommodate projected year 2000 traffic. In order to determine the percent traffic impact M+' at the intersection caused by the proposed development , the amount of site generated traffic and year 2000 traffic were compared , By year 2000 it is estimated the intersection will have a total approach volume of 3360 vehicles during '. . the PM peak hour . This number was determined based on existing year 1991 traffic and the year 2010 projections contained in the County ' s report , As agreed to by the County , a straight line traffic growth factor was used in k • making the year 2000 projection . d EXHIBIT .

DATE: February 7, 1992 ' :t` d t, ' The original proposal had been scheduled for a public hearing before the Board on January 20, 1992, following a Planning Commission hearing held on January 13, 1991. As Exhibit 11 ' illustrates, the Planning Commission was asked to review a modification to the Westlake PUD master plan and a Class II variance to LODS 18.020(3) in order to allow a limited access (right I I, in/right out only) on Kruse Way. Those requests were denied by the Planning Commission. The . applicant requested that the Board's hearing be continued to February 19, 1992, so that they can submit revised information and so that citizens are provided an adequate opportunity to review } the information. The applicant has submitted the following exhibits for the Board's review: Exhibit 51 Letter by Steven K. Routon (OTAK),dated January 24, 1992 Exhibit 52 Letter by Daniel A. Seeman (Kittelson &Associates, Inc.), dated January 31, 1992. Exhibit 53 Revised Site Plan Exhibit 54 Revised SanitLy Sewer&Water Plan , Exhibit 55 Revised Storm Drainage &Grading Plan Exhibit 56 Revised Landscape Plan (for Kruse Way Subarea) Exhibit 57 Revised Site Lighting Plan ` ` Exhibit 58 PUD 3-80(Mod. 11-91)/VAR 15-91-931 —Findings, Conclusions &Order .. Based on an analysis of the information above, staff makes the following findings: Wetlan l : v • As Exhibits 53 and 56 illustrate, the elimination of the Kruse Way access will reduce the project ` impact on the existing wetlands on the site. While the impact area will be reduced from .32 "• acres to .24 acres, the proposed mitigation area will remain the same at .34 acres, Exhibit 51. . .. `' For a detailed staff analysis and discussion of the wetland issue please see the January 10, 1992 staff report, pages 8 and 9. 9 I '' ,`'ll " ‘ \1t'Iltlt, • I'1)a((11Iht`Bo% 110 • I-.1k,(14WV1*,t),(�Yt'1;1)11'�i(1 i4 t Hammitt 111‘1,0,11 1+1111 h`r II,2,UI) • jilllktIllli;1 II%1'.U�II,Cillli111{i-113tp1 • 1•A\(it); Iti i 11;,1d1 L Transit. Exhibit 53 does not illustrate the proposed pathway from Parkview Drive to Kruse Way (as was shown on the original site plan, Exhibit 11). Kruse Way is a public transit corridor, with transit facilities at its intersections with Carman Drive and Westlake Drive. Therefore, to comply with the requirements of LODS 6.020(1) and (2), the above pathway should be reinstated in order to provide adequate pedestrian access to adjacent transit facilities. The pathway location should be designed so as to minimize any conflict with the wetlands along Kruse Way, The pathway t should provide a pedestrian connection through the site to connect Parkview Drive and Kruse ' Way. This will further implement Plan policies which require safe convenient access enabling ', residents to travel safely on foot or bicycle throughout the community, Transportation Policies, General policy VI. 5. utilities: As Exhibit 11 illustrates, the project was originally designed with three access point, two on Parkview Drive and one on Kruse Way (a limited right—in/right—out driveway), On January 13 , 1992, the Planning Commission denied the Kruse Way access alternative,Exhibit 58. The applicant has since revised the site plan and other supporting evidence, including the traffic report. The supplemental traffic report p (Exhibit 52) indicates that even without the Kruse Way access, the project will continue to function within acceptable level of service during the morningand evening ' peak hours, with minimal traffic related impacts to the adjacent streets and t .h nearby intersections. These findings are consistent with earlier findings in Exhibits 36. A The traffic reports (Exhibits 36 and 52) also identify several improvements necessary along Kruse Way at the intersections of Kruse Way and Carman Drive and Westlake Drive, These „.÷ improvements would be needed to accommodate the project traffic for the year 2000. While the evidence suggests that the improvements may not be necessary at this time, staff finds that the applicant's participation is necessary to adequately address these needs. Therefore, the applicant will be required to sign a nonremonstrance agreement for future improvements of the above intersections. CONCLUSION 4 Based upon the information submitted by the applicant and staff findings presented in this report, . t, staff concludes that DR 15-91/PD 6-91 can be made to comply with all applicable criteria by the application of certain conditions. r. .=I; RECOMMENDATION ' Staff recommends approval of DR 15-91/PD 6-91, subject to the following conditions: A.

Since that original analysis was submitted, the alternative access that was being proposed (onto Kruse Way) has been denied. This letter summarizes the findings and ', Ai r recommendations of the analysis for the development, assuming that exclusive access is provided via two ' driveways on Parkway Drive. Based on the results of the analysis, the proposed site can be developed as planned with minimal traffic- related impacts to the adjacent street system and nearby intersections, The significant findings and recommendations are as follows: • • The key signalized and unsignalized intersections within the study area are currently operating at an acceptable LOS during weekday morning and evening peak hour conditions. • Upon completion of the development,the site driveways and key off-site intersections • will continue to operate within acceptable level of service limits during the morning and evening peak hours. ` ; • . • The traffic analysis conducted for this project is consistent with the the Buttke report, `M• prepared for the Westlake PUD in 1979 and amended in the early eighties. The current traffic patterns in this Westlake development am consistent with the previous traffic , '• assumptions and conclusions containeed in the previous traffic reports. The analysis indicates that this development will not adversely impact the surrounding street system, LLw • The Westlake Drive/Krse Way intersection will require the addition of a right-tum lane d, ._ c" • on the westbound approach to the intersection to be able to accomodate projected year " ` 2000 traffic volumes. Both the northbound and southbound approaches to the Carman Drive/Kmse Way intersection will need to be widened and improved to allow for the provision of separate left-turn, through and tight.tum lanes to be able to accomodate projected year 2000 traffic volumes.

According to the applicant's traffic report (Exhibit 16), the 26 existing street system in the neighborhood is adequate to accommodate the site N> • 27 generated traffic, without the proposed direct access on Kruse Way. 28 — The Kruse Way access will be injurious to the public, since it will cross a heavily 29 used pathway along the north side of the road. The applicant failed to 10 adequately address safety related issues with respect to both pedestrians and 31 bicyclists who use that pathway [LOC 49.510(1)(B)]. 3 2 — The proposed Kruse Way access also will be injurious to the neighborhood, by r . 3 3 having a negative visual/aesthetic impact on the recreational use of the existing a ., . , 34 pathway [LOC 49.510(1)(B)]. This access will require removal of large . segments of the existing landscaping along that road. The landscaping currently PAGE functions as a vegetative buffer, separating the pathway from the road. • • 3 PUD 3-80(Mod. 11-91)\VAR 21-91-931 J; . x • , • • x • M1 9 M • ..0 _ • c' • • 1 ORDEZ 2 IT IS ORDERED BY THE PLANNING COMMISSION of the City of Lake Oswego • that: a` 4 1.

I was very careful to purchase a house that did not back up to a public area or apartments. It was my understanding, as • . the original plan, that I would have •` houses behind mine. Instead a large wetland mitigation pond was approval/put behind my house. As a result, the back of my house now looks through this open space into Parkview :, �; Drive and the proposed apartment development. I am opposed to this project. The main reason relates to traffic as well as the noise and safety issues associated with it. The developer went before the Planning Commission to ask for a modification of the Westlake Planned Unit Development master plan in order to introduce a direct access point on Kruse Way. Without this modification, the proposed project is entirely unacceptable to me. If there is any way that the Development Review Board can send this back to the Planning Commission or to City Council, I think that it `r'' should. The residents in the Westlake area have expressed concern over the traffic problems � for As you know, a large track of houses on small lots as well as a commercial ;� � • ears,y. development have already approved a roved on Parkview. I feel that the PlanningCommissions findings were not sound. A) They used the applicants traffic report which may or may not ' really reflect the amount of traffic that will be on Parkview when all projects are completed. B) They claimed that a Kruse Way access would be injurious to the public since it would cut across the bike path. This bike path is interupted by several other streets at several other points, One more street stop would not make it suddenly dangerous. C) The Planning Commission felt that a Kruse way access would have a negative visual aesthetic impact on • the recreational use of the existing pathway. I feel that the noise and safety problems on • Parkview are much more important to the neighborhood than how one very small portion of a r: r bikepath looks. Since Parkview Drive has been opened through to Carmen, there has been a great increase in noise at all hours of the day and night, I feel that there will be too much traffic and noise on Parkway Drive with all the other approved projects for an apartment complex to be approved in addition and don't support this M project, However, if it is approved I feel that the Kruse Way access must be there. It is very unfortunate that the Planning Commission would rule against a request of such importance •*$ that both the residents and developer agreed upon. +- . E X H I B I T 4.

My house backs upthe wetland to wetland , takemitigation pond north of.Parkview (see enclosed pictures). I am veryunhappy and quantity of the plants (and seriously hope that more work will place ng it, includinith the g more mature plantings, in the near future). I feel this development should be required to } a have more mature plantings on both Parkview and in its wetlands mitigation area. :.s Also, I would like to see some evergreens put in front of the apartments on Parkview. 2) I attended a pre-hearing meeting some months back with the developer. I greatly i. appreciate the fact that they did set some of the proposed apartment Parkview after this discussion, The DominionP buildings back farther off plan had a fence along Parkview. Since this developer eliminated that fence, I would still like to see Building A on Parkview on ' 'corner of the development set back a little farther from the street, the NW Thank you for fakir the g time to consider my concerns. y Sincerely, • Cynthia Johnson • ;l • yr • Attachment: Wetland mitigation pond photos +Z ` 4„ y54 ., R. • • .. .

Lake Oswego, Oregon L'l' February 24, 1992 7 t r f City Cou 1 City ke Oswego " I 2 6 199 380 Street - La Oswego, Oregon 97034 r Dear City Council Members: It is our understanding that; a 352 apartment complex is being considered off Kruse Way, near the church that is being built on the corner of Kruse and Carmen. Due to the high traffic density that now occurs, we do not believe it should be allowed. S 1' Please consider the following: « 1.)Traffic density on Quarry, the road Westlake residents primarily use to reach • Bonnas Ferry, is nearlybumper y at 35-40 miles m�per to bumper at rush hours. Moat drivers travel this street per hour.

Page 9 FINDINGS , CONCLUSIONS ANC) ORDER h t '1 I'p t .1 st 7. March 28, 1992 Dear Development Review Board Members: .r ;,; • This letter is written to express my concern about DR 15-91 the proposed ap artments p po on Parlcview Drive.My concerns will focus on flaws in their application as it relates to traffic. The intersections that I will focus on are Kruse Way and Westlake, Kruse Way and Carman,and the interior intersections are Westlake and PaskIand Parkview and Carman. `f4 ,A ttj i,2, First,the applicant has relied on prior traffic studies as a basis for his own traffic analysis. I have spent many hours reviewing these prior traffic studies and they are not an appropriate basis for this application because they fail to address the interior intersections that will be impacted by this application.I will give you a brief synopsis of these prior traffic reports. I also request that each of these traffic studies be physically entered into the record. • The 1976 Kruse Way Study looked only at Kruse Way.The traffic impact on the intersections affected by this application weak'not considered and the traffic issues were not resolved. A' The 1978 Transportation Plan for Lake Oswego did not look at collector streets and intersections internal to Westlake.Again,the traffic impact on the intersections F', s affected by this application were not considered and the traffic issues were not `: , resolved. V • In the Original 1979 Buttke Report,the intersections addressed were limited to the s "' west access point,now know as Kruse Oaks Boulevard and the east assess point, now know as Westlake Drive,at their intersections with Kruse Way.The focus was on the Kruse Way corridor and the major intersections at Kruse Way.The traffic at the intersections most impacted by this application were clearly not considered and the associated traffic issues were not resolved. • The 1982 Kruse Way Corridor Study, done by ATEP, also focussed on the Kruse Way Corridor.The purpose of this study was "to perform a transportation planning A analysis of the Kruse Way Corridor." In this report, they go on to say "the Kruse Way Corridor includes Kruse Way and all streets or properties abutting or taking direct access from Kruse Way,which are Bangy Road, Carman Drive, Boones Ferry,and to a lesser degree, Bonita Road,Meadows Drive,Fosberg Road,and Quarry Road."The intersection of Westlake Drive with Kruse Way was given only , ,: very minimal consideration, In fact,ATEP states on page 13 of this report that the r Westlake intersection with Kruse Way is not shown in their analysis tables due to :`" ': their minor cross-traffic volumes.The minor cross-traffic volumes ATEP ' predicted at the intersection of Westlake and Kruse may in part be due to flaws in K` I h this study, For example,one flaw is that this study failed to include all areas north �• 1 of Melrose,This flaw is shown in Figure C-1 and in Tables S-1 through S-4, Clearly the intersection of Westlake with Kruse was not fully addressed and the ' traffic issues were not resolved as part of this study. And the streets and i• ntersections internal to the Westlake Development,which are the intersections { ; most impacted by this application,were not addressed at all, Clearly the traffic ; • . EXHIBIT rPf3 CP-15 11 PP (rill " , I+ • 1 , " . , t a r 7. • J.. r , r. r y7;�":r ti iK� ': issues associated with this proposed development were not addressed and were note resolved. ' v ti. • The 1983 Kruse Way Corridor Study again focussed only on Kruse Way and the major intersections of Kruse Way. It did not address the intersections most impacted by this application and the related traffic issues were not resolved. • The 1984 Buttkke Report,and I quote from that report,"analyzed the traffic impact `^� at the intersection of Kruse Way and Westlake Drive." Again,the intersections most impacted by this application were not considered and were not resolved. • The 1990 Traffic study which was done for the Westlake Elementary School only :`; reviewed the intersections immediately adjacent to the school site and does not \-' include the intersections most impacted by the application before us tonight.The traffic study for the school is also flawed in that it looks only at the 1990 traffic volumes and then adds the predicted traffic impact of the school.It fails to take into . account the developments that have been approved but had not yet had a traffic impact in the area.It does not look at traffic in a comprehensive way and it does not address or begin to resolve the traffic issues related to this application. It is clear that these reports do not address the intersections and streets that will be most , impacted by this application.It is also clear that none of these traffic studies resolve the traffic impact of this application.To approve this proposed development would clearly t violate the Comprehensive Plan. Now let's move on and look at the claims and flaws made in the traffic analysis done for this application.In Exhibit 36,Table 1,page 5,the applicant makes the claim that with only ,. existing traffic,the intersection of Kruse Way and Westlake is at service level C.The applicants traffic study shows these new appartments alone at peak PM hours will generate an additional 125 vehicles at the intersection of Kruse Way and Westlake.In table 3, the ` applicant claims that with existing traffic and the additional traffic generated by this ' application,the intersection of Kruse Way and Westlake will go to service level D. So ' ' according to the applicant,this development alone will cause a degradation of one full service level. ` Now let's look at an independent traffic study done by the Clackamas County Department _ of Transportation. (I also ask that this study be physically include in the record of this u application.) According to the Clackamas County Department of Transportation,the existing traffic at Kruse Way and Westlake is at service level D.Contrary to the applicants .•:. assertions, the current service level is already far worse than the applicant claims it will be after their project. If we use the independent traffic study and then add the applicant's own projected impact, the service level at the intersection of Kruse Way and Westlake will degrade from the current level of D to service level E. Clearly,the roadways are not ;' adequate to support this application and clearly this application must be denied Now let's move on anti Yok at the developments that have been approved but have not yet had a traffic impact.Past,let's look 4t DR 13-90,the commercial property located at the corner of Parlcview and Westlake Drive,that was recently approved by this board.Exhibit 21 of DR 13-90 clearly shows that an additional 130 vehicles will impact the Kruse Way ' and Westlake intersection at PM peak as a result of the commercial site alone. Again, using i� ;I t.y na .. . � ' 4' 3 t 5 J Y n.. � aatA a ' 1. the independent traffic study, we see that with only the commercialJ r ` intersection of Kruse and Westlake will degrade from service level D to property,ice level E. ' ' °.~'. addition,within the Westlake PUD, this board has approved Westlake 89 with approximately 200 single family units.Westlake 1C2 has an additional 24 single family units, Baycreck IV and V have an additional ,Melrose Estates has 65 family units 1 5 . 17, Kruse Ridge has 30,and Pheiffer has another 43.In total there are an additional 379 single family units that have been fully and completely approved but have not yet impacted traffic levels in the Westlake area. All of these approved but as yet not fully developed projects • .,� will impact the intersections under consideration tonight.Clearly this application is flawed. It does not look at traffic in a comprehensive way, • f D i { f i To summarize the material I have just written I have included the following table: ,Existing Traffic PM Peak Impact �A Plicants Claims.. Ptes>>4lting'1Craffwc bevels . Level C i 125 additional vehicles i independent Study Level+D 125 additionalLevel E vehicles Level E and Apartments i (Voilates Comp.

Plan) ' approved ' i development Finally let's look at the Comprehensive Plan.The comprehensive plan polices relevant to traffic,including street capacity and safetyissues are stated in the Comprehensive Plan •r Impact Management General Policy II which says: "y The City will evaluate zoning and development proposals comprehensively for their impacts on the community,requiring the developer to provide appropriate solutions before approval is " 2a goes on to state that"The Citywill ° granted. Specific Policy prepare and carry out regulations requiring development proposals to identify and satisfactorilymitigate adverse impacts,including: " traffic or safety improvements needed for access,circulation,parking of autos, bicycles and or pedestrians; separation of auto and other circulation or to reduce or eliminate traffic impacts on adjacent areas,or to facilitate use of public transportation."These policies require a new development proposal to demonstrate that streets and intersections in the area have capacity to safely accommodate the new use. Through this g point I have focussed primarily on the interesection of Kruse Way and Westlake, The evidence I have already presented about the intersection of Kruse and Westlake shows that this application violates the comprehensive plan and must be denied. t ,But let's move on to look at the other interior intersections in the Westlake area that will be ",' impacted by this application. "". 4. 4 '' First,I have to point out that the original Westlake PUD hearings did not address or resolve the traffic issues for these interior roadways. In exhibit 36, the applicant makes that claim that the traffic analysis for this project is consistent with the traffic reports done for the original Westlake PUD hearings. But if you go back and review these traffic studies, FY. r p ` 'e , you will find that there is no evidence that traffic issues for the interior roadways were ever even addressed and therefore the traffic issues certainly can not have been resolved. Let me speak plainly here, the traffic issues for the interior roadways of Westlake have never been address.,ed and have,• a never been resolved. 1 Now let's move on and look al the applicants claims about the interior roadways.The applicant claims that the intersection of Parkview and Westlake current operatesY But we have demonstrated that the applicants traffic analysis under estimes service levels by a full service level. Since the traffic analysis for this application is so inaccurate and inadequate at the Kruse and Westlake intersection, ' the interior intersections have also been ssl underestimated.e In t the service levels for reasonable to assume that the intersection of Parkview and Westlake is currenact, it is tly at service level D and would be at level E if this application were approved, Clearlythis i. would violate the comprehensive plan, this Finally,I would like to briefly point out several other flaws in this application.First, the applicant's traffic counts were conducted in August.According to Frank Ch4rbonneau, who is a traffic engineer working this city,August is an innappropriate time to do traffic •counts in a residential area, Mr. Charbonneau;lliat traffic usage and volumes would be greatly reduced in August since the residents often are on vacation, tend tolse their cars in favor of walking or biking,Mr. Charbonneua also noted that Westlake is the main street that is used to access the Oak Creek Elementary School and since it was not in the time,traffic usage and volumes would be even lower. Clearly the applicant's traffic at , analysis is seriously flawed, I would also like to point out that in Exhibit 36, the applicant states that "Westlake 4 Drive/Kruse Way will require the addition of a right-turn lane on the westbound approach t. to the intersection to be able to accomodate projected year 2000 traffic volumes". "Both the north and south bound approaches to Carman Drive/Kruse Way intersection will need to ' be widened and im ,•` po'cved to allow for provision of seperate left-turn, through and right- , , turn lanes to be able to accomodate projected year 2000 traffic volumes." But the independent traffic reports show that we are at or verynear year 200(� applicant falsely claims that the "improvements identified not warrented a on volumes. The completion of this development,but rather will be necessary at some time in the future as traffic volumes within the study area begin to approach the evidence is clear from the independent traffi y that year already rev The" But evidence shows that the improvements are needed now, ' f i . v 1.•,if Now let's look at what it would take to make the improvements that the applicant has R identified.According to Ron Weinman,Clackamas CountyTransporation improvements proposed by the developer would require that Kruse Way be Planner, widened. According to our City Charter,any street widening is subject to the vote of the Since this proposed development is depend on these improvements, this widening of Kruse Way,the r p oposal can't be approved until the street widening is ensured. Since no such vote bythe people has occured and is not scheduled and the outcome of such a vote is •. 1 completely unknow this application can not be approved at this time. The applicant has clearly failed to show that the streets and intersections in the area have sufficient capacity to accommodate the traffic generated by this issues have not been fully resolved, Clearly traffic generated by this application on top ect. Clearly the f of r1 • • f s • the real existing traffic levels will result in traffic levels that are not in compliance with the • Comprehensive Plan. Under these conditions, this application must be denied.

Any "Pass ' By" trips should show up in the driveway volume projections. "Pass By" trips are those trips attracted to the - t. site from the "Pass By" traffic flow (ie. existing traffic on Westlake Drive or Parkview Drive that would be passim;, by • ' with or without the commercial center), ' a The trip generation appears low, The report used two of the most generalized land uses; Shopping Center and General Office. reasonable assumptions can be made about the use of this site, which would significantly increase the site trip generation (50-100%). This site will attract Y ,• convenience type commercial uses and customer contact oriented office uses, These kind of uses are high trip generators, Also, there Is a lack of similar shopping oppoqunities within this affluent neighborhood, which will result in higher than average trip making rates, i //lair pp r 4 4 1 } ,: 1 • •,l f ,i ,1 .

Further assumptions• concerning the makeup of the commercial site were made and • are also included in Table 1. It is estimated that this PUD would add ' approximately 21, 500 vehicle trips to the adjacent street system on a typical weekday . That is , 10, 750 vehicles would enter the site and 10, 750 would leave the site daily. The corlunerc� �' .�a1 • portions of the site are expected to add nearly 10, 000 vehicle trips and the residential area is estimated to add ". 11,600 vehicle trips per day as shown on Table 1, The � , ::• P.M. peak hour (4 : 30 to 5 : 30 p.m. ) traffic is expected to be approximately ten percent of the daily volume . During the0 P.M. peak hour, approximately 57 percent of the hourly . volume is the site while 4 expected to enter p3 percent of the traffic would leave the site . • For traffic analysis purposes , it was also assumed that '., the ; r land along the south side of Kruse Way between Rangy Road and Carman Drive would also be developed.

After internal streets are con- structed, it is estimated that approximately 50 acres of land could be developed into industrial uses . It is estimated that a 50 acre industrial park would add • approximately 2600 vehicle trips to the adjacent street system on a typical weekday . During the P.M. peak hour some 60 vehicles could enter the industrial park and 400 vehicles leave it . r • Assi`nment of Site Traffic The traffic volume generated by the proposed PUD was assigned to the adjacent street system on the basis of a trip distri • bution and assignment process developed for the Transportation Element of the Comprehensive Plan for Lake Oswego. The ' ' internal trips distrit .,ed between residential and other uses within the PUD were reduced during the calculation of the site generated traffic which would be added to the CARL H BUTTKE, INC CONSULTING TRANSPORTATION SNOWIER • . . ro • adjacent street system. Therefore , the volumes shown on Table 1 were distributed and assigned to the street system outside the PUD, y The assignment of site generated traffic added to the adjacent streets is shown on Figure 3. As indicated on Figure 3 , it is anticipated that the site wild, add nearly 11,000 vehicles per day to Kruse Way immediately east of T-5, nearly 6000 vehicles per day to Kruse Way east of Carman Drive , about 3000 vehicles per day to Fosberg Road north of the site and approximately 1000 vehicles per day to Botticelli northeast of the site . '� During the P .M. peak hour (4 : 30-5 : 30 •, 'r p .m. ) which is expected to be the most critical time period for the adjacent street ti system, 1.t is anticipated that 490 vehicles would leave the site at the westerly access point on Kruse Way and 540 vehicles would enter there . The anticipated peak hour turning volumes are also indicated on Figure 3. p, At the easterly access point for the site on Kruse Way, it is estimated that ap proximately 180 vehicles would leave the site and 325 vehicles would enter the site during the P.M. 34 "l '. peak hour. r 411) . . . .; . . . ... . •-.. .

This year 2000 traffic was estimated from the results of 'the Phase II analysis1 of the Transportation Element of the Comprehensive Plan. Modifications to the estimate of passing traffic were made because the land south of Kruse Way and the Mt. Park Towncenter is assumed to be different than that utilized in the Phase II transportation analyses. The assignment of the year 2000 traffic passing the site and not oriented to the PUD is shown on Figure 4 .

For these calculations , it was assumed � 4, that Kr e us Way , would be four lanes with left turn lanes and that the site access roadway would be 40 feet wide with one inbound lane and two outbound lanes. ` ` The comparison of year 2000 P.M. peak hour traffic and the capacity of the intersections on Kruse Way is shown on Table 2 . This comparison indicates the percent of the in ter- section capacity which would be utilized by the peak hour traffic , otherwise referred to as the volume to capacity `, ratio. As indicated on Table 2, all intersections on Kruse Way '''''.1: , ; would experience conditions where the peak h;�ur traffic is expected to be less than the capacity if the site were to remain vacant and the remaining undeveloped areas of Lake re : . , .

If this were done , the traffic volume is expected to utilize approximately 94 i,'. percent of the intersection capacity. The double left turn lane probably would not be required v,ntil .. about 1990 or until the westbound Kruse Way traffic increases to require the double left turn movement .

This roadway is recommended to connect to the i 4;1 easterly access road north of the neighborhood commercial site and be aligned in the northwesterly direction to the west access road. It is expected that this connection 1 would discourage through traffic movements but provide adequate internal circulation. � ' , a Access to the north on Melrose, Fosberg and Rodgers should be as originally proposed. 1 • Access to the east at the intersection with Fosberg Road and Carman Drive should be provided with a two lane roadway widened at the intersection to provide a left turn lane .

KRUSE WAY CORRIDOR STUDY July 1982 Introduction In June 1982, Associated Transportation Engineering and Planning (A'FP ) , Inc. was selected by the City of Lake Oswego, through a competitive process, to perform a transportation planning analysis of the "Kruse Way Corridor" . This report is the result of that analysis . ' Kruse Way forms the west gateway to the City of Lake Oswego. It forms '. `1 the major connection between Lake Oswego and the Southwest Portland Metropolitan Area. it begins at the terminus of State Highway 217 and ends at Boones Ferry. The "Kruse Wa + :> all streets or properties abutting or taking odirect laccessudes rfrom use 6JKruse ay d "' `, Way, which are Bangy Road, Carman Drive, Boones Ferry, degree, Bonita Road, Meadows Drive, FosbergRc'iad, and and to a lesser � Quarry Road. The lands abutting Kruse Way have designated land uses as shown in the fi City ' s Comprehensive Plan. All of these lands are within the City' s Urban Service Boundaries . The lands south of Kruse Way east .of Bangy Road and west of Carman Drive are in Clackamas County but outside the .. ' City Limits and carry somewhat different land-use designations in the , County' s Comprehensive Plan. Element 12 of the City' s Comprehensive Plan addresses "Transportation" . The City ' s Plan was developed in 1977 . The Transportation element ;: r. assumes designated land uses and shows year 2000 traffic volume projections. However, since 1977 the designated land uses have been changed or are proposed to be changed; thereby superceding the previous traffic volume projection. Scope of Services • The ultimate goal of the City of Lake Oswego is to allow development in . . such a manner as to maintaia a traffic system on Kruse Way, Carman .f Drive, Boones Ferry Road and Bangy Road that functions at Service Level D or better., It has been determined that the following information is required: s Development of P.M. peak hour , year 2000 traffic on Kruse Way, from I-5 to Boones Ferry Road. Identification of P.M. peak hour percent of total A.W.D.T. and directional splits. Identification of P.M. peak transit assumption.

I I The traffic volume projections shown in that Plan were based upon existing traffic volumes (see Figure 1) and the proposed land uses. The traffic generated by or attached to these proposed land uses were ►.4C assigned to "traffic zones" . The City was divided into 37 "traffic ,zones" with the area outside the City divided into 3 "traffic ,r zones" . The traffic assigned to each zone was to travel on an assumed arterial street network forming "links" between each zone." _ Traffic could also be assigned within each zone as "interzonal trip" " and thus would never appear on the "link" system. The original "traffic assignment zone" map, "assignment map" showing the "link numbers, " and the "Trip Distribution Table" are attached in Appendix ` "A" . This traffic data resulted in a year 2000 traffic volume y� projection (see Figure 2) . This original data shoved that the traa:fic in this corridor entered and exited in a proportion of 2/3 west and 1/3 east. Associated Transportation Engineering: Planning (ATEP) , Inc. , reviewed the above and other original data and pla ed it on their"in-house" computer system. ATEP ' s computer programs were able to build a "base transportation R system" to approximately pproximately reproduce the traffic assignments used itt E' 1977 within this project ' s study area. This "Base Transportaton System" formed basic traffic distribution patterns and "Lj,nk Networ%:" ' for this study area, which had been divided into 7 traffic: Study Subareas. Existing Traffic The City provided ATEP with traffic volume data for Kruse Way and; ty , " , 'a Boone: Ferry; ,� Carman Drive; and Rangy Road. The turning movement studies were converted to Average Annual Weekly traffic volumes (See M Appendix B) The 1982 P.M. peak hour volumes were analyzed and compared to the 1976 movement d4 d It Was found that at approaching Boone:, Ferry, Kruse Way traf,'"xs ,roved at 58% to the north and 42% to the south. This 1982 movement is a reverse of the 1976 movements, Which were about 58% south and 42% north. However, traffic during the 1982 P .M. peak hour from the developed � ;- . Kruse Way properties did move 2/3 west and 1/3 east, as was assumed in the 1977 Comprehensive Plan. ' ATEP calibrated its "Base Model" to reflect 1982 travel patterns. ni` 'e ,..8_ y ..r f A © r ,. .,re.` YI t• .+ / Fht + (wyrda . tit .: I. t .y � <ti'- , ' 0 , ' j 1•1/. .. . 4 h h, i i l I . fma.e n • I l 1 • r�/� } II,. r1} K fti�� a !� .autos of E' ♦/...--""."� ewe •aafn Itt • • I..........) r: r, t 1 \ r. • .I• .a a J 6 I+ a rf a•.1'.:. �. r ^� 1• M1 / 6. a LEGEND 1.1 FIGURE C 1 a ®,.

The major portion of land within the Corridor is in the City • L, of Lake Oswego. As shown on Figure 2, the land in the vicinity ; . of Carman Drive and north of Kruse Way, as well as the land `` south of Kruse Way and west of approximately Carman Drive, is • outside the City and within the County's jurisdiction. ' The land in the northeast portion of the Corridor (east of ' Carman Drive and north of Kruse Way) is zoned generally for yd ; office campus uses, some limited commercial use, and reel- dential use. Currently, there is approximately 155,000 gross . .,. } s square feet of office space developed in this area. Table 1 . • indicates the assumed future land use for this area, as well as the other three quadrants of the Corridor. I The northwest quadrant (west of Carman Drive and north of Kruse Way) is zoned generally for residential uses, with office and commercial uses at the West end of the quadrant. Table 1 sum- • » marizes the assumed future land use. The area currently is :tl undeveloped, but plans for development of the West Lake property Vr are underway. The southwest quadrant (west Lake Oswe t Carman Drive South fKruse `. 1 Way) is outside the City go and under County juris , , , .,...i diction. The area is zoned generally for campus industrial .s I uses (which permits office space) , commercial uses, and reel- L. ky • CAfll ill Dunk,mIC L 1 .•hw • . . • • • • ••••••••••••r•••1•••r•:•1•e•••1••••••••• rl e"ores•"•"r••. • • • • • • • • • • • • • ♦ • e • •••°•°°°•°•°•"•°e"•°•°•°•°•"•°•°•°•°••• °1"•"•"•°r"•" " I °•°•°•"•°•••°•°•"s"•°•••s • e • • • • • • • • • • • • e • • • • e • • • • • • • • • • • • • • • • 1 •"•"o"•°•°••s°o°•°•°•°•°•°•°•°•°•°•°°°•••°•o°•••' s•••s••°•"ores• '{� + .

The majority of the southwest quadrant was designated in the Lake Oswego Comprehensive Plan as light industrial, which 1 i. would result in a much lower density development than under the County's Comprehensive Plan and zoning. The City of Lake Oswego I and the County, however, entered into a Dual Interest Area Agree- ment (subsequently approved by L.C.D.C. ) , establishing that the County's Comprehensive Plan and zoning shall apply to the unincor- porated portions of the Dual Interest Area, (including the south- N west quadrant) and the County shall retain authority and responsibility for all implementing regulations and landuse • I actions as long as the area remains unincorporated. Under this agreement, the City has an opportunity to review and comment on : planning actions in the Dual Interest Area. • u `. y ., This area is undeveloped, except for the original homestead and a few other dwellings. Plans are underway for development of Liberty Park at the west end of the quadrant. The southeast quadrant (east of Carman Drive and south of Kruse , i,ti- '!. . , Way) is zoned generally for office use, commercial uses, and ) residential use. The easterly portion of the quadrant, Mercan- file Village, is approximately 90 percent developed with approx- ° mately 138,000 square feet of office and commercial space. The '' westerly portion of' the quadrant has recently been approved for « development as Kruse Way Plaza with office space and some multi- family residential units . Table 1 indicates the assumed future ' land use for this quadrant. ROADWAY SYSTEM c The roadway system serving the Corridor is shown on Figure 3.

Roadways, including Carman Drive, Bonita Road, Bangy Road, Quarry Road, Fosberg Road, and Melrose Street are all two lanes, approximately 20 to 22 feet wide with variable shoulder widths and constructed oP I asphaltic concrete or an oiled base surface. ' Kruse Way and Boones Ferry are City of Lake Oswego Streets. a I Bonita Road, Carman Drive, and Quarry Road are County Roads, and Bangy Road and 1-5 are under the Jurisdiction of the Oregon ' „" Department of Transportation (ODOT) . The City of Lake Oswego is planning to construct a traffic signal at the intersection of Kruse Way and the access to Mercantile Village and the northeast quadrant. This signal would provide for left turn phases on Kruse Way and one phase to be shared by the north-south approaches to Kruse Way. The signal 'on Kruse Way at Boones Ferry Road would be inter-connected with this signal to provide a progressive traffic flow along :cruse Way. . " A condition to the Kruse Way Plaza development in the southeast , il quadrant requires that Carman Drive be widened to include a left turn lane at Kruse Way and at Quarry Road and that a left turn lane also be included in Quarry Road at Carman Drive. Kruse Way Plaza has proposed a right turn in and out only accesu' on ' ' Kruse Way and on Carman Drive. 4•t y, Currently, two local improvement districts have been established in the southwest quadrant to construct Meadows Road between Bangy Road and Carman Drive and two connections to Kruse Way. This construction is underway. ..,': ,' , :_' + I 0TIOCE.

I � The development of the Westlake project in the northwest y quadrant will include construction of local roadways and two • w connections to Kruse Way.

The level-of-service concept requires consideration .• '' of factors which include travel speed, safety, frequency of interruptions in traffic flow, relative freedom of traffic • ,' ^' y; maneuvers, driving comfort and convenience, and coat. Six :',..' standards have been established ranging from level "A" where traffic flow is relatively free to level "F" where the street 40k system is totally saturated or jammed with traffic. A descrip- tion of each service level is provided on the following page. ' 'Y Service level "D" is generally utilized as the standard for asses- ,, . ( sing urban traffic operations and design of urban roadways. It } is the policy of METRO and Lake Oswego to maintain a level of '0!: - service "D" on its major roadways during the peak periods of t operation. At level "D", there generally is at least ten percent ..'A••. more capacity available for traffic. The borderline Condition between levels "E" and "F" defines the capacity of a roadway. Y,. ( The capacity of street approaches to a stop sign controlled ' '. intersection was calculated on the ability of motorists to , cross or enter a passing stream of moving traffic on the main , street. As the passing traffic increases in volume, the avail- =" ti ,' able gaps between vehicles decrease, thus reducing'thc capacity of the cross street or stop sign controlled approach. , The current level of service of traffic operations Within the Corridor wets calculated and is summarized on Table 3.

I Corridor •Generated Traffic The P.M. peak hour Corridor generated vehicular traffic was ' assigned to the street system on the basis of this trip dis- tribution, the configuration of the street system and site 4 • access points, and the most logical route to enter and leave l `" the area. This assignment is shown on Figure 6. As indicated on Figure 6, the Corridor would attract approxi- '1 r.. mately 485 vehicles to enter Kruse Way from Boones Ferry Road and 860 vehicles to enter Kruse Way from the wept during the P.M. peak hour by the year 2000. Approximately, 860 vehicles per hour are forecast to enter Boonea Ferry Road from Kruse n. i Way at the east and 1635 vehicles to leave Kruse Way at the I west during the P.M. peak hour by the year 2000.

It assumed that approximately 5000 people would be employed within the Corridor whereas the assumed land use for this analysis, as indicated on • . Table 1, would indicate that approximately 15,000 people would be employed within the Corridor. Therefore, 10,000 more people would be employed within the Corridor than were origin- 1 I • ally assumed in the Lake Oswego Comprehensive Plan and the related transportation analyses. Ten thousand more jobs in the h Corridor means that more of the work force living in Lake Oswego, who were originally assumed to work outside of Lake Oswego„ would actually remain in the area and be employed within the Corridor. In other words, approximately 3500 workers living In t ' '' the Lake Oswego planning area by the year 2000 were originally • assumed for the Comprehensive Plan analyses to commute outside of the City to work, but none are estimated to work in the s '. Corridor. Therefore, the forecast background traffic through ' ', the Corridor and throughout Lake Oswego would be reduced to t. reflect an additional 3500 people from the Lake Oswego planning ,, `` area working in the Corridor. Figure 7 indicates the reductions in P.M. peak traffic volume throughout Lake Oswego as a result of fewer, people commuting outside of the Lake Oswego planning 4 :,,' area. I Total Traffic ,.

Data are insufficient to draw firm conclusions, but it appears that flexible hours programs have ' .` a positive effect on transit and carpool use, whereas staggered. lwork hours increase the risk of reducing transit and carpool use. There are insufficient data on the impacts of compressed workweek programs. Theoretical analyses indicate that . . compressed workweeks can significantly reduce peak period work p, tripe and congestion, althorgh there may be negative effects ' I on carpooling and transit ridership. Staggered Work Hours • ` I "With this alternative work schedule, all employees in an I organization work the same days each week and th ': same number of hours each workday. Daily starting and stopping times • of different groups of workers within, the organization ' . ,. are varied by the employer by assigning staggered starting - times--7:00 a.m. , 7: 15 a.m. , 7: 30 a.m. , etc. Employees generally have no choice in their working hours; they are . simply expected to be present each day during their ' ..

All affected pro- perty owners would be members of this organization and would provide the financial support for its operation. The function a i of this Corridor Management Organization would be to administer . ,� I and carry out the program lements, coordinate with the City of Lake Oswego, Clackamas County, ODOT, TRI-MET, and other affected • public agencies for the provision o," the necessary transporta- tion program. This organization would become a transportation �w service broker for the Corridor by providing the rideshare pro- F., gram, transit incentive program, transportation information, by organizing the alternative work schedule program, and by work- ing with the necessary public agencies for the implementation of service and capital improvements. It is not intended that this organization would engage in any land use decisions or "'",4, actions that are required by the City or County under ORS Chapters 215, 227, and 197.

" • Sale of monthly transit passes and tickets. I a • Consider providing discounts on the rate of transit passes and ticketo or providing other bonuses for using transit. t `' • Coordinate with members that walkways are provided between • bus stops and all buildings and work with Tilt-MET for the provision of passenger shelters at each stop. 41) . , • ;, llu NE,INC J l . • • 1. v� I 0 0 . 59 Alternative Work Schedule Program: ` • I • • Work with all employers to establish alternative work schedules throughout the Corridor with the goal of shifting the exiting times to hours before and after 4: 30 to 6:00 " I p.m. • • I Parking Control Program: I • It is recommended that the Corridor Management Organiza- 1 tion monitor parking needs of the Corridor and work with the property owners to determine the level of new parking • necessary with each new development. • The purpose is to ; provide a parking supply consistent with the achievement \ '. of the transportation management' program so that a parking surplus does not encourage more people to drive to work. I •A: ` • Work with the membership to provide centralized and shared " parking facilities among the various buildings on a site. In this manner, parking spaces per unit of development can be reduced in the future, as determined through the monitor- ing program, and each building would still have adequate •.. parking without an over-supply. • • Work with the membership to determine if parking charges can be levied and are feasible and if these charges can � ' be used as incentives to the rideshare and transit inoen- 'r five program. y T I " ' CARL N BUTTKE,INC ` CONMU111NG IIIA$SWhtAiION I14GP4 1 • . • . �y+ u ''' ! ,1 ' k ' ' 60 .t•.• tr• `� 1 t'• Other Transportation Modes Program: i ® Work with members to encourage employees to walk and ride bicycles to and from work. This can be accomplished through the initial design and construction of the corridor iby providing a network of pedestrian and bicycle ways { throughout the Corridor and convenient weather-protected bicycle parking areas at each building. `p' Traffic Operational Improvements: ` s Work with the members and affected public agencies to implement traffic operational improvements where andat .. , when necessary to relieve congestion and increase capacity. I Monitoring Program: • Develop a monitoring program to measure the effects of ' .i' the transportation management program. The result of the p' :y monitoring program would be input to program revisions, transportation Improvements, and traffic operations yx Imodifications. µ 4r PUBLIC TRANSPORTATION SERVICE It is recommended that public transportation service to and ° throughout the Corridor be improved as the Corridor develops. Figure 10 on page 111 indicates the suggested future service for the Corridor.

TRANSPORTATION ANALYSIS OF THE LAKE OSWEGO ELEMENTARY SCHOOL LOCATED IN `" LAKE OSWEGO, OREGON A+ 1 1` Introduction - This report represents the INTRODUCTION findings of a transportation analysis for the development of a 500 student elementary school located at the northeast quadrant of the Kingsgate and Melrose Street intersection located in Lake Oswego, Oregon. The purpose of this transportation analysis is to assess the transportation impacts of proposed development on the surrounding road system. The data collected and all kethe a , -0 G technical calculations made for this report is contained in an appendix to this report and , ' is available upon request. YI �. EXISTING CONDITIONS40 ,, : ,, STUDY AREA LOCATION The study area consists of area bounded by Melrose Street, Kingsgate " Westlake Fosbe Road. and / ►g The area is mostly residential with some of the land in the ' 1 vicinity vacant. A new city park is to be constructed on the south side of Melrose Street �, :just to the east of Kingsgate and to the east of the park, the City of Lake Oswego g has recently opened a new Fire Station. y Access to the site will be Kingsgate approximately 500 feet nort Kingsgate/Melrose Street intersection. No secondary access to the si h of the to is proposed, ` " Melrose Street is a designated Collector street in the Transportation Element of the Lake Oswego Comprehensive Plan, Through this area, it is a two lane roadwaywith sidew I •ak.� .on the south side to the east of the proposed site and on the north side between Fosberg Road and Kin s �;t�, g g Melrose Street has a posted speed of 40 MPH with an average daily traffic volume of approximately 3700 vehicles east of Fosberg Road, Fosberg Road/Westlake Drive is a designated Collector Street with Fosberg Road north 4. w and south of Melrose Street approximately 36 feet in width with sidewalks on both sides 1+' of the road.

'M TRAFFIC CONTROL 2 Currently, all the intersections along Melrose Street and Fosberg/Westlake Drive are controlled by stop signs. As proposed, the school will be oriented towards Melrose Street with all access to the site from Kingsgate. ;w►h TRAFFIC VOLUMES r ; • • The traffic volumes used in this analysis were supplied by the City of Lake Oswego traffic staff. Where data did not exist, ATEP conducted manual turning movement counts, The • ' ' counts taken during preparation of this report can be found in the Technical Appendix, .; See Figure, 2 & 3. .. CURRENT LEVELS OF SERVICE " , Level of Service (LOS) is a concept that was developed to measure how the driver `,, • perceives the conditions surrounding them as they travel through an intersection or t , roadway segment. This degree of perception includes such elements as travel time, number of stops, total amount of stopped delay, and impedances caused by other ^{ vehicles: The 1965 Highway Capacity Manual originally defined six grades of Levels of ' F - Service, these grades are shown in Table 1. Using this definition, it is generally a that "D" LOS is the minimum acceptable for an urban area. g y agreed '' ,., i For the purposes of this analysis, the assumed relationship between the calculated stopped time delay per vehicle and the associated LOS for signalized intersections is given in Table 2.

R ' Unsignalized intersections require a somewhat different approach to determine the capacity of the intersection. The 1985 Highway Capacity Manual offers the concept of 1 "Reserve Capacity" as the guideline for measuring the capacity. 4 T • Reserve Capacity is defined as "that portion of available hourly capacity that is not used." -,,' it should be noted that the concept of Reserve Capacity only applies to the individual movements of traffic at an intersection approach, either in an individual lane or a shared lane, not to the overall operation of the intersection. This determination is made after ' ; . °, all approaches are analyzed and the LOS determined is usually that approach that typifies the "Worst Case" condition or worst Level of Service. A description of the levels of service relating to the Reserve Capacity Concept is shown in Tables 3 & 4. LOS analyses. presented in this report were performed in accordance with the t' procedures described above. For each intersection, these analyses estimate the overall `; intersection LOS during the peak hour flow. ` ' ,', • T• 1 r �* � a • 4 A ,1. 77 A, kti 1 r ' Y i n .` " h ASSOCIATED TRANSPORTATION ENGINEERING & PLANNING (ATEP) PAGE 6 Table 1 - Level Of Service Definitions (Signalized Intersections) • S, AMMINtar t 4 . . ,,.. Level of Service Traffic Flow Characteristics r AVery low delay, less than 5.0 seconds per vehicle.

TRIP GENERATION • • Estimating the number of vehicle trip ends that will be generated bythe development is of prime importance to the City of Lake Oswego, 0 . . * proposed Two basic procedures are availa ble to traffic engineers for estimating the number of driveway vehicle trips generated by a proposed but not -yet -existingdevelopment: 1. Apply averages observed through field studies conducted at other similar facilities fies located throughout the United States. A number of sources are available for Tri . , this information including pJ nera Manual (4t1'i E i on 1987, which is published by the Institute of Transportation, Engineers (ITE); and summary tripgenerations prepared by the California Department of Transportation, the Arizoa Department reports Transportation, and other public transportation agencies, All of these soures vide . •. � excellent guidance in estimatingthe tripp generation rates for various land uses, but obviously do not take into account the effects of local conditions characteristics of the proposed land use. and unique 2.

NOTES: A. Units = number of proposed students .. B. Includes both inbound and outbound trips For the purposes of this analysis, it is assumed that none of the home-related person trips will be made by mass transit. This assumption ignores the recent projections that 4-6 percent of all home based person trips for purposes unrelated to work will be made • by transit. Therefore, this assumption tends to cause the analysis to reflect a worst-case . .aw'W condition, and over estimate the traffic impacts associated with this development. • .r: • TRIP DISTRIBUTION • f lw The distribution of generated trips onto the roadway system within the site area was determined by reviewing the school boundary area and the distribution pattern • r`: determined by field observations. This distribution was verified with the distributions of the morning and afternoon peak hour travel patterns shown in Figures 2 and 3. • This trip distribution was used to develop the site generated traffic for the specific driveway and street distributions as shown on Figures 4 through 7. • • l: • 4 • • ASSOCIATED TRANSPORTATION ENGINEERING & PLANNING (ATEP) PAGE 12 n Yy k1 _ t " • ''t ''' ;:•: r...................,..................,.......................„„.................... 1, p 5 NORTH o � P 0 A.

The speed of vehicles added to the crest vertical curve on Fosberg Road to the north of the Melrose Street intersection and the lack of traffic control , devices at the intersection poses a severe safety hazard to the pedestrians crossing $. ' r. : :. f Fosberg Road at Melrose Street. Additionally the lack of sidewalks on the south side of Melrose Street between Fosberg i ' Road and Kingsgate requires that pedestrians either cross Melrose or Fosberg to the north ` , side of the street and walk to the school. j; t ,:;_. The available stopping sight distance on `�°' f STOPPING SIGHT DISTANCE, Kingsgate north of the site driveways is ;° - 1 limited due to the presence of a \; horizontal and vertical curve. The site driveways intersect Kingsgate at the end of horizontal curve and the beginning of a crest vertical curve to the south of the intersection and will have an approximately 6% slope at the stop bar. The available sight distance for anyone exiting the site driveways onto f Kingsgate was measured both directions north and south along Kingsgate. r In conducting the sight distance investigation, the procedure followed was to place a 6" high object in the site driveways at the proposed stop bar location and then measure along Kingsgate to a point where at 3 ft 6 inches above ground the 6" object could be ' : seen. This method of determining "STOPPING SIGHT DISTANCE" as indicated by the . "American Association of State Highway and Transportation Officials" publication " A Policy on Geometric Design of Highways and Streets", 1984., page 158, "It is considered that , • a 6-in.-high object is representative of the lowest object that can create a hazardous condition and be perceived as a hazard by a driver in time to stope before reaching," �`' ` This was done for both directions along Kingsgate and it was found that to the south °A along Kingsgate the available sight distance was 165 feet. The sight distance available 7 to the north along Kingsgate toward the horizontal curve was measured at approximately 240 feet. \'. In order to determine the required stopping sight distance for vehicles on Kingsgate, the actual speed of the vehicles using Kingsgate needed to be measured, The City of Lake 4 ASSOCIATED TRANSPORTATION ENGINEERING & PLANNING (ATEP) PAGE 18 t S 4:. t r r, , 1 r1 �'. t• Oswego conducted a vehicle speed study approximately 500 teet north of the proposed driveways. During the four day traffic speed count it was found that the 85% speed cf vehicles through this area was approximately 30 mph. The posted speed on Kingsgate is 25 mph. yi. The required stopping sight; distance for a vehicle travelling 30 mph was calculated using the formula for stopping sight distance as shown on page 143 of the "American Association of State Highway and Transportation Officials" publication " A Policy on Geometric Design of Highways and Streets", 1984. using a grade factor for a 3% down ' grade. This grade factor was chosen because at the point of decision for the vehicle on Kingsgate (approximately 175 to 180 feet north of the site access point) the grade was t established to be approximately 3%. Using the methods described above as the Worst possible condition, the required stopping sight distance for a vehicles travelling at 30 mph on a 3% negative (down) grade was 210 feet. This is adequate for the south bound traffic. The stopping sight distance Y for the north bound vehicles was measured using the same criteria mentioned above and was found to be 165 feet. The required sight distance for this movement was calculated ' to be 132 feet, • `' This investigation indicates that there is minimum safe stopping sight distance along j�. `' Kingsgate for the vehicles entering and exiting the main site driveways. The stopping sight distance was measured along Fosberg Road to the north of Melrose ••••' Street and was determined to be approximately 330 feet of stopping sight distance , available. The required sight distance was calculated by the methods mentioned above and was found to be approximately 360 feet. • `1• This indicates that the there is not adequate stopping sight distance along Fosberg Road at the Melrose Street intersection. • No transit service is provided within the TRANSIT CONSIDER.TIONS vicinity of the proposed site , 1 • 4 , 1'• • •i ASSOCIATED TRANSPORTATION ENGINEERING & PLANNING (ATEP) PAGE 19 ` µ' v. u } CONCLUSIONS • q 1 p i`: 1. The site will generate approximately 516 new vehicle trips per day and 8 trips (2 t• t in and 6 out) during the pm peak hour when complete. 2. The intersections within the study area will operate at an acceptable level of service after construction. 3. The main site access point will operate at a good level of service. 4. The intersection of Fosberg Road and Melrose Street does not have adequate stopping sight distance for vehicles southbound on Fosberg Road. -A.1• Recommendations - Based on the results • RECOMMENDATIONS of the traffic access analysis described in this report, it is concluded that the property as proposed can be constructed with minimal impact to the surrounding street system. To ensure the safe and efficient movement of traffic and pedestrians within the area, the following traffic operational improvements are recommended. 1) Designated school crosswalks be installed at the Fosberg Road/Melrose Street at the north and east leg of the intersection. 2) Designated school crosswalks St reet/Kingsgate be installed at the Melrose Street/Kingsgate intersection across the north and east legs of the intersection. 1 O • ,a 3) A sidewalk be installed on the south side of Melrose Street from the end of the existing sidewalk to Melrose Street. 4) The City of Lake Oswego consider making the Fosberg Road/Melrose Street ` intersection a three way stop to protect pedestrians crossing Fosberg Road. ` `" :° 5) In the future, the City consider closing Kingsgate at the north line of the proposed t site driveways. This should be considered at the time the property to the west of the site develops. This will eliminate residential through traffic from passing directly in front cy the main school entrances.

Mr. Keech in his review of the ATEP report makes several assumptions that are not correct and I tend to mislead the non-traffic engineer. First Mr. Keech indicates that the driveway volumes appear to be low. The trip generation numbers used for the analysis were approved by the City of Lake Oswego Engineering staff and are consistent with the types of trip generation volumes assumed in the Kruse Way Corridor >. Study;Buttke 1983. I agree with Mr. Keech on the approach to determining driveway volumes but must disagree on his assumptions that the volumes are low. Mr. Keech also indicates that reasonable assumptions can be made about the use of the site. `` Trip Generation rates used in the preparation of the ATEP review are the accepted standard for all kinds of developments. Mr. Keech's assumptions for the type of businesses that will come to this location are not based ". in any fact and just because the trip generation categories used are general in nature does riot mean that the trip generation is low.

The analysis indicates that this development will not adversely impact the surrounding street system. The current traffic patterns with this development are -: consistent with the previous traffic assumptions and conclusions contained in the previous traffic reports.

A Street Lake Oswego, OR 97035 SUBJECT: Westlake II Tr ansportation Analysis Addendum .4. Dear DRB Member,;:- P There were numerous issues raised at the March 30th Development Review Board hearing for the Westlake II multi-family housing project. This letter, in combination with the traffic analysis previously conducted by Kittelson & Associates (dated August 18, 1991) addresses these is sues. The key issues that are addresses in this letter are: 1. The traffic study performed by Kittelson & Associates assessed existing conditions on the road e system fry addressing August conditions. August is g typically a very light traffic rna►tt;`i, because • ,x; " school children are not in session. Therefore, the Kittelson analysis Is flawed. ;'''`' For the traffic analysis documented in the August 1991 letter, Kittelson conducted traffic ;v. counts during an average weekday between Tuesday and Thursday in August, 1991, In that �k study, Kittelson assumed that August conditions are reflective of typical weekday conditions. ODOT traffic volume counts at several permanent counter stations in the general area support this assertion. The table below shows the ratio of average August traffic volumes to average annual traffic volumes at numerous indicative locations in the Portland urban area. As shown in this table, August traffic conditions are generally higher than the average over the course of the year. At all permanent count locations nearest Lake Oswego, August counts were over 100 percent of the annual average. In fact, August conditions represent between 103 and 120 percent of the annual average at these locations. This evaluation revealed that, in all cases, August traffic conditions are significantly greater than annual average conditions. This clearly indicates that the Kittelson analysis represents a reasonable assessment of typical conditions on the study area road system, •• 0 41, 4 Development Review Board Members April 3, 1992 T Page 2 5. • des' , • SEASONAL VARIATION IN TRAFFIC VOLUMES r. on Major Roadway in the Portland Urban Area ry FACILITY AUGUST AVERAGE PERCENT MONTHS OF ANNUAL (Close to AVERAGE 100%) -- I-5: North of Terwilliger 1039'0 Sept.

A more recent spublished tudy by Clackamas County, entitled the Lake Oswego Tra►sportation (January, 1992) reported that the eadsting level of service of the Kruse Way/Westlake intersection is "D", while the Kittelson analysis reported it to be "C". If the Kittelson analysis was incorrect about its assessment of existing conditions, isn't it reasonable to assume that its assessment of future conditions is equally flawed, and that therefore this road system would really breakdown in the future despite the Kittelson analysis findings? a The traffic counts that ''ere used by Clackamas County as a part of the Lake Oswego Transportation Study analysis were performed in September 1990. Kittelson conducted counts in August 1991 for the August traffic study, representing more recent traffic conditions. Thus, the Kittelson analysis represents a more up-to-date assessment of traffic conditions on study area streets. Lake Oswego and Clackamas County staffs reviewed the level of service analysis worksheets prepared by Kittelson, and concurred with the results. The Clackamas County study shows that the Westlake/Kruse Way intersection will operate «. with an average stopped delay per entering vehicle of about 29 seconds, while the Kittelson study shows the average delay to be 21 seconds per entering vehicle. The level of service at a a signalized intersection crosses the threshold from LOS "C" 0 "D" at 25 seconds. These Y 'µ..TA differences are insignificant to the overall findings and conclusions of the traffic study. The0 r. J . Vi* • i ice' • Development Review Board Members April 3, 1992 Page 3 key finding is that both studies indicate that there is substantial excess capacity at this intersection to accommodate future growth. • 3. The Kiuelson analysis, as well as virtually all other previous analyses (including those analyses conducted by Bunke,ATEP and Clackamas County)failed to analyze the long-term future level of service at the intersection of Westlake & Parkview and also on these two streets 4 themselves. Therefore, these analyses did not assess the most critical elements of the road system in this area. ,' r The Kittelson analysis considered the existing conditions, plus build-out of the proposed apartment complex. This analysis showed that all key intersections will continue to operate 1 safely and at sn acceptable Level of Service upon build-out of the proposed apartment complex. With regard to the long-term operational characteristics of Westlake & Parkview, the original 1979 Buttke study did estimate future traffic volumes on Westlake and Parkview, and on that r, AL basis recommended roadway cross-sections to accommodate projected future traffic demands. We have reviewed the Buttke ana'.ysis, and concur with said findings. Specifically, g pe ally, the existing roadway cross-sections on both Westlake Drive and Parkview are more than adequate to accommodate the long-term growth traffic within the study area. 4, The Development Review Board does not have sit cient data to approve the proposed project, because a comprehensive traffic analysis has not been performed. "4 te' % ' There have been two comprehensive traffic analyses conducted that document the future traffic .:" conditions upon buildout of the Westlake area. These analyses include the Report on Tragic Impact-- Westlake Planned Unit Development (Buttke 1979) and the Lake Oswego. Transportation Study (Clackamas County, 1992). These studies both concur that future traffic conditions in the area will operate at acceptable levels with minor improvements at the two key intersections on Kruse Way at Westlake and at Carman. At the hearing, Mr. Barton made the statement that Westlake Drive will need to be widened to accommodate future traffic volumes. That statement is not supported by the findings of fact.• a•' To the contrary, in addition to the two studies mentioned above, Ron Weinman (Principal Transportation Planner at Clackamas County) wrote in a letter to Jerry Baker (Lake Oswego . • ozer • j 1 • d Development Review Board Members April 3, 1992 `r • Page 4 r;• Traffic Engineer) dated October 28, 1991 that the existing cross-section of Westlake Drive, at • its intersection with Kruse Way, is adequate to accommodate the proje&ted 2010 traffic. •S. The Kittelson st udy 'is flawed because it did not address Internal circulation. ,, > •. • In addition to the major intersections with Kruse Way, the traffic study submitted by Kittelson Y , & Associates, Inc. also evaluated traffic operations at the proposed site access with Parkview, as well as the immediately adjacent off-site intersections at Westlake/Parkview and Carman/Parkview. The results of that ar,.al sis revealed that Y all key intersections will operate within acceptable Level of Service limits upon build-out of the proposed apartment complex. Finally, we have reviewed all traffic related information submitted to either the City or Clackamas • • County regarding the Westlake transportation system, and said review does not change any of the findings or conclusions of our analysis. I trust that this letter adequately addresses the issues raised in the March 30th hearing. I look forward to answering any questions you may have regarding these issues at next Monday's hearing.

Committee to review and update the transportation element of the City's comprehensive plan. This was necessary because • many of the current transportation policies are out of date. ; { A twenty-four member Transportation Committee consisting of ; , City neighborhoods, business representatives, and members at large worked with the City and Clackamas County staff to {: ensure that local concerns are addressed. The committee met for nine months to review and recommend various transportation programs and projects. Many of these '. recommendations are the results of the disires that were reached by this group. Three of the committee's objectives were: 1) To reduce through traffic from neighborhood streets. 2) Concentrate traffic on major streets. 3) Maintain the character and livibility of xA • the community. This technical memorandum presents a summary of a comprehen- sive analysis of the transportation system within the City of Lake Oswego. By means of computer modeling, existing and ' future traffic operations are identified and a number of staged transportationz improvements are recommended. This memorandum examines short, mid, and long range transportation needs within the study area. Short range (0-5 Years) tra" -7ortation projects for the City include eleven projects with ..,:, estimated cost of $5 380 000 (Projects 1 to 17V . (Figure 1 Mid range (6-10 ' aars) transportation capacity improvements for the city include fourteen projects with an estimated cost of $3 ,905, 000 (Projects 12 to 25) . , Long range (11-20 years) road improvements include thirty- , one projects at an estimated cost of $8,585, 000 (Projects 26 ' to 56) . In addition, four projects are listed as Traffic Studies at an estimated cost of $160, 000 (Projects 57 to "� 60) . ` The total cost of the transportation improvements for Lake • Oswego will be $18,030, 000. The proposed roadway improvements include both major and minor facilities as well as intersection improvements within '' the City. (Figure A-13) , Recommended changes to the functional classification of streets within the study area have been completed as part of the Transportation Plan Update. The previous functional . Y Y , i + •t ' r.J ti classification system is divided into four new categories which are: Major Arterial • Minor Arterial ▪ Major Collector ▪ Neighborhood Co llector ol.lector Figure A-6 shows the proposed Functional Class System. • • \. e 1 +' • • • • • • f: --''',. ••.,'), •. ..

INTRODUCTION 1.1 Purpose of the Study • a t The purpose of this study is to assess the need for short and long term transportation improvements in Lake Oswego's ' N Urban Area. Three objectives of the study e; ' ° 1) To reduce the through traffic from neighborhood streets. 2) Concentrate traffic en major streets. 3) Maintain the character and livibility of the community. +YI �'' By means of computer modeling, using the EMME/2 transportation planning software, existing and future problem areas are identified. A number of transportation h '` improvements addressingthe P problem areas are recommended. The overall objective of the study is to analyze existing t •1 ' (1992) and future (2010) traffic operations and recommend long term capacity improvements for the City. 1.2 The Planning Process °s • The planning g process followed for the development of this Plan consisted of a systematic analysis combined with input . and review by the City's Transportation Committee (TC) . The .14 TC was assigned by the Lake Oswego City Council to review .`'and update the transportation element of the Comprehensive Plan. The TC consists of twenty four members representative of the City's neighborhoods, business interests and at large f members. The comm3,ctee meetings were held monthly for nine , r + months to provide review and staff, guidance to the City and County 1.3 Study Area The study area is the urban services area of Lake Oswego. Lake Oswego is the Clackamas Count principal city on the westside of Y• It is adjacent to the southern boundary a2 • of the City of Portland west of the Willamette River. It is bounded by the Willamette River on the East, Washington County and I-3 to the West, Multnomah County to the North and Clackamas County and West Linn to the South.

In identifying improvements, a number of alternate courses of action are recommended. The emphasis was on identifying improvements which are low-cost, quick to implement, and make maximum use out of existing facilities. 1.5 Methodology Traffic volume forecasts were prepared using the Metro ''.1'44 Traffic Model for year 2010 population and employment data. the Portland metropolitan, region has been divided into • "travel zones" each having assigned population and employment data. , The transportation model generates the number cif vehicle trips into and out of the travel zones based on population . , t and employment data. The forecast traffic is then distributed onto the street network. For analysis of subareas such as Lake Oswego, a more Yf detailed street network is coded into the model. Travel zones were further divided to provide better control of population and employment estimates within each zone. Alternative street networks are modeled with the sets of population and employment data, each of which reflects ,e specific assumptions about further development in the subarea. 1.6 Data Collection . 1 The information collected for this traffic analysis includes • regional travel forecasts and regional population and employment forecasts from the Metropolitan Service District. Lake Oswego Traffic Engineering staff also provided existing traffic volume counts, background maps, and aerial photos. � y" t �' 9 • y . 3 Y• 1 S .r 1 +.. r ♦ r�- I f l .4 .. -1 ,.

The RTP includes ma j or '1 t` transportation improvements to provide adequate mobility on, and access to the region's transportation system within recognized financial and environmental constraints. `, Appendix A includes the RTP recommended improvements located in Lake Oswego. }• Clackamas County Comprehensive Plan The Clackamas County Comprehensive Plan adopted, in December 1989, establishes general transportation goals, designates new roads and realignments for the urban area, and identifies the functional classification of existing and proposed roads. In addition, the Plan further describes .. strategies and projets to improve the transportation system. A list of the projects located in Lake Oswego and documented s : in the Clackamas County Comprehensive Plan is described in Appendix B. Lake Oswego Comprehensive Plan The Lake Oswego Comprehensive Plan, adopted in July 1978 addresses major transportation issues and calls for detailed street, intersection and access planning for certain areas, .,.'! especially commercial districts. r 3• EXISTING TRANSPORTATION CONDITIONS. 3.1 Functional Classification System Figure 2 shows the City's existing transportation classification plan which was adopted in l978, indicating designated arterials as well as collectors and locals.

ThesOregonOsw�.go Si � Department of Transportation (ODOT) owns and maintains 1 Highway 43 and 1-5 within the Lake Oswego City limits. Clackamas County is responsible for Rosemont, Stafford,Childs, and Pilkington Road. ";u The functional classifications are defined in Lake Oswego as follows: Freeway - Freeways are intended to , •, o •: . movements of large volumes of traffic between the pCity iand ous r. regional or State destinations.

Arterials are designed to " provide through traffic with safe and efficient travel conditions and, therefore, will vary in design to serve expected vehicle traffic. Kruse Way, for example, is designed as a four-lane limited access highway with left and ' right turn refuges, raised landscaped median, interconnected signalized intersections and minimum access to adjacent properties. This design number of shared access calls for frontage roads, a minimum points to serve adjacent properties and a Class I bikeway. Traffic Volumes on the variety of Lake Oswego streets which function as arterials are expected to vary from 6,000 to 45,000 vehicle trips p per day at full development. Necessary vehicle travel lanes will vary from 2 to 4, with left and right turn refuges or acceleration lanes where needed. Traffic volumes expected at full development, terrain features and planned uses of the right-of-way will determine street design and number of travel lanes. ( See Street y Design Standards, General Policy VIII. ) - L Collector Street - Collector streets connect traffic between arterial streets, activity y " A centers and neighborhoods.Collectors are principal traffic carriers within '�: . '' neighborhoods, carry some through traffic from other neighborhoods and provide some access to abutting land. The - average weekday volume expected on Lake Oswego's collector streets at full development of the community 2,000 and 17,000 vehicles per day. ranges between The number of vehicle travel lanes will vary from 2 to 4 (with left and right turn lanes as needed) . Traffic volumes expected at full development and planned u='K`rs of right-of- way way will determine the street design ar' +r..u;ber of vehicle travel lanes. H.3.2 Existing Traffic Conditions The existingr� performance of major streets in the City was , • evaluated using current traffic volume and analyzing existing traffic congestion in terms of "level of service" . As volume increases and speed decreases, the level of service gets progressively worse. A. 6 •. 1 S. .Q W V 1 ' , r w M •rl A 3.2.1 Level of Service r Level of service (LOS) is a concept developed to quantify the degree of comfort affected to drivers as they travel r through an intersection or roadwaysegment. LOS is based on calculations of the reserve capacity at an unsignaliaed intersection, the average sto r < ' '4`' experienced by motorist at a signalized intersection, and the volume/capacity ratio along an arterial. A letter grade ,: :9. from "A" through "F" is determined from these calculations LOS "A" is the best rating, while LOS "F" indicates failure , h of the system. LOS "D" is considered the minimum rating to i rj achieve in planning for the improvements. Appendix e explains level of service concepts in more detail. Highway Capacity Software (HCS), a microcomputer software F program, was used to calculate level of service for intersections under existing .conditionsThin software is based on the 1985 Highway Capacity manual. �,' r Figure 3 shows traffic volume and traffic congestion for some of the roads and intersections with an unacceptable i, , level of service.

It establishes guidelines for locating pathways, guidelines for their development, funding sources, and public hearing process to insure conuinuing community involvement and a process for revision and updating the plan and map. The Pathway Plan has identified the major pedestrian/bicycle routes based on existing community need. f 4 In general, the plan is consistent with the Clackamas County 4 ‘, Comprehensive Plan. As a part of the development of this plan the Pathway Advisory Subcommittee, after extensive public participation, has identified the following corridors y*.• ' . as those which are currently of the greatest public need: n• Figure 4 shows gu pathways in Lake Oswego. 14 Upper Drive 2.

There are five fixed routes (35,36,37,38,78)that serve the City. Tri-Met Line 35-Oregon City operates on Highway 43, Tri-Met Line 36 also along Highway 43 and Tri-Met Lines 37 and 38 along Boones Ferry Road provide bus service to the City (Fig. 5 ) . Tri-Met currently maintains and operates one transit center in the City„ This facility is located in central Lake Oswego, providing connections for line 35, 36, and 37. Transit patronage was examined in 1985 and 1990 by Tri-Met. In 1990, in the Lake Oswego area, approximately 1860 passengers used these lines on a typical weekday. In 1985 the ridership was about 1830. } Lake Oswego Comprehensive Plan encourages public transportation, and cityng develop a future park ndsride facility with Tki-Met to within the City. 1• r • • • • • • • • .y, is • • 11 • • �• s . r I a ,4 1 n l f v. t� f 't , 4 y.: 1 1 . .....- STUDY AREA , .: 1,1 1.g �1,' �. ,r• �..Il",..rl' \ y,�t. .V c'' � ,' +� I, ` 'SJ , II' " .b�,'�,{.W- � LAKE OSWE00' +�7)f• , 1.11.■I, "�'. -irA 1 },1 t�' 11..':` all. :w� ^'s«'iF M.w' ;'l.. —:--.. . ~/�` 1M •I.'

FUTURE TRANSPORTATION CONDITIONS . 4.1 Proposed Functional Classification Following is the list of the street classification recommendations by the City of Lake Oswego TC. Under the recommended system, four new categories are added to the list, those are: Major Arterial, Minor Arterial, Major s Collector and Neighborhood Collector. As part of the Transportation Plan Update, TC reviewed the existing functional classification definitions and based on the characteristics and functions, they made a number of changes. The changes were made to reflect how the roads ' actually operates and how Lake Oswego wants them to operate. , :, The goal is to maintain the City's character and livibility. Figure 6 shows the Ci tation classification plan, indicatingsdesignated ed rarterials as well as collectors and locals.

In this system, the Portland ' Metropolitan Region has been divided into "travel zones" . Each assignedpopulations ., g and employment data. The transportation program generates the number of vehicle V '. trips into and out of the travel zone based on the . ; population and employment data. The traffic forecast is ' then distributed onto the street network. For analysis of a subarea such as Lake Oswego, a more detailed street network for that area is coded into the model. Travel zones are further divided to provide better control of population and employment estimates within each zone. 4.4 Population and Employment Assumption 4.4.1 Lake Oswego Population and Employment Growth ; :, Population and employment growth is summarized in Table 2. The growth pattern illustrated in Figure 7 and 8 represent an increase in population over the next 20 years by 12, 969 ;, (40%) and in jobs by 3,737 (34%) . . • , . , . . Population: 0 The impacts of ` P population growth on transportation system include significant traffic increases on Highway 43, Kruse Way and Boones Ferry Road. Presure on arterials and collectors linking travel zones 1,4,5, 6 and 12 to Highway 43 and I-5 will increase. Access along Highway 43 will become more difficult due to ;. a 1.. , congestion. The major population growth area will be within the Boones • Ferry and Kruse Way areas which will increase by 490 percent. Other areas that will have significant population increase will be adjacent to Highway 43 and Childs Road. �' Employment: Major employment growth is expected in the Boones Ferry Kruse Way Corridor areas percent increase in a 124 and zones 4,5 and 7. Employment p yment in the Highway 43 area is expected to increase by only 2 percent. • .. . ....or The projected employmentgrowth as well as through traffic, will increase traffic congestion on Highway 43, Boones Ferry ; • Road and Kruse Way. • p, . , o • it 18 Y 1 . r, TABLE 2 LAKE OSWEGO POPULATION AND EMPLOYMENT ,n;1. ; ;' 1987 - 2010 e POPULATION EMPLOYMENT DISTRICT Name 1987 2010 Change : 1987 2010 Change •y } 1 First Addition 3,207 4,075 27% : 3,382 3,431 1,5% •,,' ' :4' 2 Forest Highland 3,067 3,401 10% : 740 826 11% 3 Mountain Park 4,406 4,891 11% : 338 436 20% 4 Westlake/Holly Ord. 1,515 8,923 490% : 838 1,881 124% 5 Rural Lake Grove/Bta. 2,057 3,822 33% t 1,850 3,341 80% 6 Bryant/Rosewood 5,392 6,263 16% : 1,698 1,857 9% 7 Lake Gove/Lakeview 1,848 1,849 0 4 605 1,088 79% 8 Blue Heron/Palisades 4,660 4,797 3% : 131 161 22% ? 9 Mcvey/Southnhore 2,160 2,548 18% : 454 544 20% 10 Marylhurat/Nallinan 1,444 1,868 29% : 541 742 37% 11 Rosesont 885 1,076 21% : 83 85 2% , 12 Westridge 652 1,549 137% : 33 38 15%t; •32,093 45,062 : 10,693 14,430 , , 4 y • Refer to the Figures 7 and 8 Source: METRO, June 1991 MF-6/18/90 ,' ,r.

The growth pattern indicates a regional increase of nearly half a million new people and 300,000 new jobs over next 20 years. Washington • County is expected to attract the largest share of the population growth (145,000 people) and will house 24 percent of the regional population in 2010. Clackamas County is ` ., expected to increase by 113,000 , 21 percent of the regional 2010 population. Clark County .is expected to add 110,000 • people, also increasing its share of regional population by 2 percent. The most rapid employment growth will occure in the suburban districts. Major commercial centers are developing in the • v. suburban areas. These employmnnt concentrations in the Gresham, I-5/Kruse Way, Clackamas Town Center, Sunrise Center, 1-5 Corridor, Beaverton, Sunset Corridor, Hillsboro and Tanasbourne areas will provide focus for suburban residents to both work and shop within their subarea, thus reducing the overall need for long distance trip-making. As a result , the Portland/Multnomah County share of the region's employment is likely to decrease from 56 percet in 1987 to 48 percent in 2010. The largest increase in employment occurs in Washington County, which is expected to gain 104,000 new jobs by 2010. However, in spite of a reduced share of employment, the established areas in Portland are expected to experience an increase of 93, 500 new jobs. In addition, the downtown Portland sector alone is expected to remain strong and increase by 33,000 new jobs. •` ,`. .i pry • • • s ` is, .M • f 22, Y p d ' j , w + t -etc `•;'o,I. 4.5 Transportation Model (EMME/2) Scenarios A number of future (year 2010) transportation network scenarios were modeled using the EMME/2 software. '' A 1987 base year model was constructed and calibrated with existing traffic counts: The following future scenarios were developed: 1. No-Build Alternative: The year 2010 no-build alternative was r " developed to show traffic volumes forecast on the existing street network and the impact to the road system if no ` additional improvements are done within the study area. ' This is used as a base for comparison with the traffic 0, forecasts of the build alternatives. L 2. Build Alternative: The objectives of the build alternative are: t b A. Concentrate traffic on the major street system, and . B. Reduce through traffic on the neighborhood streets. Based on these objectives, the build alternative include the ,.. . r, following: , '... a. Reduce delay within the Country Club, A Street, and "• `'4 Kruse Way corridor. rr` b. Upgrade intersections on State (HWY 43 ) Street. c. Develop Childs as an east/west arterial while reducing through trips on South Shore. ;; di. Extend Waluga/Firwood to either Kruse Way or Bonita. d2. No Waluga/Firwood extention to Kruse Way . ;.' .r. 4.6 Traffic Analysis of u Y' year 2010 Alternatives 4.6.1 Travel Demand The projected increase in population and employment in Lake ' Oswego between existing and 2010 will result in a similar increase in travel demands„ Between existing and 2010, the vehicle miles travelled (VMT) is expected to ,increase by about 44%. This increase in traffic can seriously affect transportation system performance. Particularly, work trips tend to compete for the capacity of the roads and when it is least available during working and evening Y " peak hours. As � `'R=•: shown in Table 3, this change in traffic will increase the delay to the motorist by about G9%. In addition the average speed is expected to decrease by about 18%. •. .t • 23 :N a v1 '' Y , s • t • 0N' , A 1 , Y.: y I.' e ' ' x 1,f ti T Lc' 3 i LAKE OSWEGO DELAY AND VOLUME ON LINKS (PM PEAK HOUR) . 1 r•' I �� • " 1 Alternat3.ves • t ATTRIBUTES i Y r n►maaoaaaa m\rmrrrrar 1I + + 1 MMMMMM MINI rrlrMMMMMMMMMMaMMMar• 1 �� T saaaariaaaaaarrr 1 f SP % C0 Q. f 1 III a a a a a a a a a a aaaaaaaa 1 •d Ex.:sting i20, 547 1 A 7 +� fl 1 • 648 2®� 5`f1I dL.

With the no-build a alternative, congestion appears on the following roads and ,' '7 intersections / A i 1 • � Sri I i Y•, Hwy. 43 from Terwilliger Road to West Linn ' "�'; Boones Ferry Road from I-5 to Jean Road • ' Kruse Waybetween Bangy and Boones Ferry Road Bryant Road between Upper Drive and Boones Ferry Road Rosemont Road between Stafford Road and Hidden Springs V Intersections (Table 4) Stafford Road/Childs Road ' {` Rosemont Road/Stafford Road McVey/South Shore Country Club/Boones Ferry Borland/Stafford Kruse Way/Bangy . Kruse Way/Westlake Kruse Way/Carmen 1 Kruse Way/Boones Ferry State/McVey State/A St. State/B St. State/Terwilliger Without widening or i;itersection impvovements, all these •` locations would experience congestion. (Level of Service E or F) . Even without any development in Lake Oswego under existing } :'' conditions, con estion appears , •I g on the locations that were listed ,"' before. These congestion and intersection failures along Kruse -__'. Way, Hwy. 43 and Stafford Road would cause severe delays and unsafe conditions to motorists. The results of the no-build i � ^ scenario indicate that capacity improvements will be needed on L: '. existing road networks. Table 4 shows the LOS for the major intersections under the no- I • build and build alternatives. Figure 9 contains traffic forecasts for the no build scenario. . Road links with LOS D through F and failing intersections are identified. The no-build alternative allows congestion on existing road links to further deteriorate. Traffic would attemptto bypass ypass the ,• V4, congestion by using other roads and infiltratj;iy into residential ;a. "'°• neighborhoods. Other impacts include waster ',+1,1, air pollution and motorists frustration with travel delay . 1, 1 1 • '�. y ,,,.. O. r 'S 25 • `' W 1 N r 1.

EXISTING AND FUTURE TRANSPORTATION' NEEDS IN LAKE OSWEGO The transportation projects identified in this section are based on safety concerns and level-of-service. In response to the estimated traffic increase and congestion, many of the 1 arterials must be improved or reconstructed. These improvements include widening, adding turn lanes, signals and connect pedestrian/bike facilities. A detailed listing of the proposed projects with cost estimates are included in this sec-.ion. Short range (0-5 years) transportation improvements for the Lake Oswego include a total of eleven projects with a cost of "' $5,380,000. Mid range ( 6-10 years) transportation capacity improvements include fourteen projects with an estimated cost of $3,905,000. Long range ( 11-20 years) road improvements include thirty one projects with at a total cost of $8,585,000. In addition, • four other Traffic Studies projects are listed under long zsnge with an estimated cost of $160,000. • The total cost of the transportation improvements for Lake Oswego will be $18,030,000. The list of the proposed projects and estimated cost of each , ,`; is shown in Table 5. Figure 13 shows the location of the • projects.

In addition, fours ro an estimated identified as Traffic Studies at an estimatedts cost of $160,000 are included (table 5) . The total cost of these s Project,3 is $18, 03(7,000, It is essential that the projects be completed 'according to the staging plan between 1995 and 2010 to provide adequate transportation facilities to the City. Projects staged beyond 1995 are needed to provide improvements and additions to the City's arterial syst^m. These include upgrading • •orJ ` Ferry Road to 5 lanes bweenruse/Way, and nMadrona, widening Bryant Road to 3 lanes and improvements to Highway 43. The transportation model used in this m • stud indicates that Kruse Way/Boones Ferry and Highway 43 will be over capacity by 2010 if population and p° �., employment growth continue as anticipated. Solving transportation on-going problems in the area will be an g g process. In addition to the proposed improvements, Lake Oswego must develop a Transportation rl System Management Program to further enhance the use of other transportation modes. e '� l r/mf/0524:elk 7• • w 39 . • ,.• •.. . ,•. ... • • •, ;‘,...,', ,.., " . , . . • . . .,,'.:••',:`''',• . ...' ., . •. ,„ •. . .
