Ordinance No 2642 and the approved Development Agreement - LU 14-0021 (Exhibit F-7 of this report E. City Charter, Section 40 FINDINGS Background/Existing Conditions: 1. The site is approximately 7.35 acres in size (Exhibit E-1) and contains an existing structure that will be remodeled and situated on the proposed Lot 9 upon completion of the serial partitions (Exhibit F-2). There are mature evergreen trees along the perimeter of the site and a cluster of mature deciduous trees adjacent to the existing house on the north portion of the site. LU 14-0031 Page 2 of 27 The site slopes down towards the south at between 12-20% and is located at the northeast corner of Knaus Road and Goodall Road, both of which are classifed as neighborhood collectors (Exhibit E-2). 3. The site is zoned R-7.5, as are the properties to the south across Knaus Road and the southwest across Goodall Road (Exhibit E-2). Properties to the east and west are part of unincorporated Clackamas County. Properties to the north are in the City of Portland and/or Multnomah County. All surrounding properties are developed with single family homes. 4. A minor partition request by the applicant to divide the site into three parcels, consistent with the stated first phase of the proposed Master Plan, was approved in 2013 (LU 13-0044). V. REVIEW AND APPROVAL PROCEDURES A. Neighborhood Meeting The applicant held a neighborhood meeting with the Forest Highlands Neighborhood on March 26, 2014. The minutes of the meeting are included in this report as Exhibit F-8. B. Public Notice to Surrounding Area The City has provided adequate public notice and opportunity to comment on this application pursuant to LOC 50.07.003. No comments were received prior to the publication of this report. C. Burden of Proof Per LOC 50.07.003.1.b, the applicant for a development permit shall bear the burden of proof that the application complies with all applicable review criteria or can be made to comply with applicable criteria by imposition of conditions of approval. The applicant has provided sufficient evidence to enable staff to evaluate the proposal. These documents are listed as exhibits at the end this report. VI MINOR DEVELOPMENT A. Classification of Application Section 5.2 of the Development Agreement (Exhibit F-7) states that the Master Plan shall be reviewed as a minor development. This process is consistent with review of partitions and subdivisions. See LOC 50.07.003.14.a.ii(9). B. Criteria for Review of Application Per LOC 50.07.003.14.d.ii, for any minor development application to be approved, it shall first be established that the proposal complies with: LU 14-0031 Page 3 of 27 1. The requirements of the zone in which it is located; R-7.5 Dimensional Standards [LOC 50.04.001.11 The site is zoned R-7.5. Per Section 5.2 of the Development Agreement (Agreement), the Master Plan must be found to be in compliance with the applicable Lake Oswego Code provisions and requirements of the R-7.5 zone as they existed on May 7, 2014, the effective date of the Agreement. Upon approval, these site development limitations will be locked in and regulate future development in the project. Maximum Density This section is superseded by Section 2.2 of the Agreement (Exhibit F-7), which states that the maximum density is 16 lots, and the development's density must be consistent with Exhibit B of the Agreement. As Exhibit E-4 illustrates, the applicant is proposing 16 lots, consistent with Exhibit B of the Agreement. Minimum Density This proposal is not subject to minimum density because the Master Plan authorizes a series of partitions, and partitions are not subject to minimum density requirements of LOC 50.04.001. The Agreement authorizes development of the site at a maximum of 16 lots developed in a series of minor partitions over a period of two years. Lot Size, Lot Dimensions Section 2.2 of the Agreement states that the development density must be consistent with Exhibit B of the Development Agreement. Section 5.2 of the Agreement states that the standards and criteria of the Code, as it existed on May 7, 2014; are applicable. The minimum lot size requirement in the R-7.5 zone is 7,500 square feet, and the minimum lot dimensional requirements are 50 feet for lot width at building line. As indicated on Exhibit E-4, all of the propose lots are well above the minimum lot width requirement, as well as the lot sizes which range from 11,340 square feet on Lot 11 to 26,729 square feet on Lot 9 where the existing house will remain and be remodeled. The lot sizes and dimensions proposed are consistent with Exhibit B of the Agreement. This standard is met. Setbacks Height Limits Lot Coverage, Floor Area Per Section 2.3 of the Agreement, for any future development on individual lots, setbacks will be those required in the R-7.5 zone that were in effect on May 7, 2014. The required setbacks in the R-7.5 zone are as follows: Front Yard: 25 feet Rear Yard: 30 feet Side Yard: 5 -foot minimum with a total combined width of 15 feet Staff notes that the lot lines on Lots 15 and 16 that abut Knaus Road are considered the front lot lines, and hence the front yards abut Knaus Road, no matter how the future dwelling may be oriented.. Because both lots have frontage on the future internal street as well, they are "through lots" and thus there is no "rear" yard, LOC 50.10.003.2 "Lot Line, Rear" Definition. As illustrated on Exhibits E-4, all setbacks of the zone can be met. LU 14-0031 Page 4 of 27 The height limit required by the underlying R-7.5 zone is 28 feet on flat lots, 32 feet on lots with sloping topography, and 35 feet on sloped lots measured to the ridge of the roof. Staff notes that height is measured from existing grade and if there are cuts, height is measured from the cut grade; if there are fills, height is measured from the original natural grade per LOC 50.10.003 - Height of Building. The applicant has submitted a preliminary grading plan (Exhibit E-7) showing partial grading on the portion of the site where the new street will be located. Compliance with building height on individual lots will be assured during building permit review. For future development on individual lots, the lot coverage limitation will be the maximum allowed in the R-7.5 zone that was in effect on May 7, 2014. Lot coverage for the R-7.5 zone is between 25 and 35% depending on the height of the structure. Compliance will be assured during building permit review. For future development on individual lots, the floor area (FA) limitations will be the maximum allowed in the R-7.5 zone that was in effect on May 7, 2014. FA is dependent on lot size. Compliance will be assured during building permit review. 2 R-7.5 Structure Design Standards FLOC 50.06.001.2) These standards as they existed on May 7, 2014, including Garage Appearance and Location standards, are applicable to future structures on individual lots. Compliance with these standards will be assured during the building permit approval process. These standards are also applicable to the existing dwelling that will remain on Lot 9 because the Master Plan establishes a new lot upon which the house is to be sited, with new lot lines from which the standards are measured. Compliance with these standards will be assured at the time of issuance of building permits for each lot. Special Street Setbacks [LOC 50.04.002.5] The special street setback is to assure an adequate front yard setback is available in the event of possible future street improvements, such as additional lanes, pedestrian and bicycle facilities, transit facilities, drainage management improvements, lighting, and street landscaping. All yards are measured from the special street setback line. Per Section 5.2 of the Agreement, future development on the proposed lots must meet standards and criteria of the Code on the effective date of the agreement. Knaus Road has a special street setback of 30 feet measured from the center line of the road (as established pursuant to LOC 42.03.135). Prior to the first partition of the site (LU 13-0044), the existing right -of way was 40 feet; therefore, a 10 -foot special street setback applied to the Lots along Knaus Road. In anticipation of future street improvements for this development, the applicant dedicated 11 feet along Knaus Road and 11 feet along the Goodall Road frontage because of the street frontage improvements that would be required for this development. Therefore, no additional special street setback will be required because the special street setback is satisfied by this dedication. z Staff is aware that the applicant is considering asking for additional floor area per lot, beyond what the R-7.5 zone allows. However, that request is subject to review and approval by the City Council because it requires an amendment to the approved Development Agreement. LU 14-0031 Page 5 of 27 2. The Development Standards applicable to a Minor Development [LOC 50.061 Parking [LOC 50.06.0021 This standard requires that a single-family dwelling provide one off-street parking space. This standard may be satisfied by garage parking for single-family residences. Exhibit E-4 illustrates that each lot has sufficient area to provide a dwelling including a garage that will contain its required off-street parking. Compliance with this standard will be assured during the building permitting review process. This standard is met. Access/Access Lane (Flag Lots) [LOC 50.06.003.1] This standard requires that every lot abut a public street for a width of at least 25 feet and that the proposed point of access be adequate for the site based on the topography, traffic volume generated by the development, and classification of the public street from which the access is taken. It does not appear that any of the lots will need direct vehicular access to Knaus or Goodall Roads, however, the proposed driveway locations are not shown on the plans and access to Knaus or Goodall is not prohibited as long as they are constructed to city standards. As part of the building permit application for each lot, a site plan will be required showing the location of the proposed driveway approach for each lot to the internal street, Highland Loop or to Knaus and Goodall Roads. This standard can be met. On -Site Circulation — Driveways and Fire Access [LOC 50.06.003.2] This standard contains the geometric design standards for proposed driveways that act as fire department access roads, and other design features such as maximum permissible slope and the width of driveway approaches. All driveway approaches shall be located and designed so that the driver entering or exiting the driveway can see approaching traffic for a sufficient distance to make a safe entrance or exit. The American Association of State and Highway Transportation Officials (AASHTO) standards shall be used in determining compliance with this standard. In addition, on corner lots the nearest edge of the proposed driveway to the intersection shall be no closer than 30 feet when measured from the projected curb of the street that is the most parallel to the alignment of the proposed driveway. This standard also regulates aspects of design related to emergency vehicle access. The new internal street, Highland Loop, is over 10% grade. Public streets shall not exceed 10% grade per the Fire code, however, the Fire Code does allow 15% grade if residential fire sprinklers are installed in the future homes. This will be made a condition of approval. Staff notes that a portion of the new road is on Tax Lot 501. The applicant states that the area of right- of-way for this improvement and for the internal street, have already been created through separate dedication deeds (Exhibit F-1), which are on file. Finally, the Engineering staff states that for driveway approaches connecting to the new internal street within the development the maximum width of a driveway approach, measured where the edges of the driveway meet the right-of-way, shall be governed as follows: Single-family residential with garage door(s) facing the street: 12 feet per garage or carport stall, or surface parking space, but not to exceed 30 feet. Single-family residential with side -loading garage: 24 feet. LU 14-0031 Page 6 of 27 For driveway approaches connecting to Goodall or Knaus Road, there are design guidelines in the City Engineer's policy memorandum, Guidelines and Standards for New Streets and Frontage Improvements in the Urbanizing Rural Fringe and Transition Neighborhoods, effective February 1, 2005, describing that driveway approaches shall be asphalt and limited to 16 feet width, irrespective of the number of garage doors facing the street. The above will be conditions of approval. As conditioned, this standard is met. Local Street Connectivity [LOC 50.06.003.4] This standard applies to any development that results in the construction of a street to ensure that the layout of the local street system does not create excessive travel lengths or limit route choices, accomplished through an interconnected local street system and accessways designed to meet the needs of pedestrians. The site is subject to this standard because a new public street is being proposed. This standard prohibits the construction of new closed-end local streets unless certain exception criteria are met. As indicated on Exhibit E-4, there are no closed-end streets proposed. The new street, Highland Loop, which is being dedicated by a separate deed, connects Knaus and Goodall Roads. This standard is met. Park and Open Space [LOC 50.06.0051 This standard requires at least 20% of the gross site area be preserved as open space or park land in a subdivision. The site is approximately 7.35 acres and 20% of the site would be 64,033 square feet or 1.47 acres. As illustrated on Exhibit E-5, the applicant proposes to designate 1.61 acres (70,525 square feet) of the site as open space in private open space easements in the front and side yards of the lots along the perimeter of the site and along the internal road frontage. This amounts to approximately 22% of the site, allowing areas for driveways, with a net of 20% open space as required. As a condition of approval, the final plats shall indicate the open space easements. The applicant will also be required to record a Notice of Development Restriction with the partition plats that puts the property owners on notice as follows: "Private Open Space Easements on all lots shall be planted and maintained per the approved Landscape Plan (Exhibit E-6) to provide a scenic and aesthetic appearance of the open space." To ensure that the scenic appearance is maintained, staff also recommends a condition of approval to prohibit fencing within the open space easements. Maintenance of the open space and landscaping, discussed below, will be the responsibility of the Homeowner's Association through the recordation of an access easement and maintenance agreement. This will also be made a condition of approval. As conditioned, this standard is met. LU 14-0031 Page 7 of 27 Landscaping [LOC 50.06.004.1] This standard requires all partitions involving the creation of a street to provide street trees at the proper spacing for the species, and requires screening and buffering to mitigate noise, lighting or other impacts from adjacent transportation routes or dissimilar uses. The applicant's Landscape Plan (Exhibit E-6) indicates Crimson King Maple and Zelkova as street trees along Knaus Road and Zelkova and Bosque Elm along Goodall Road. Along the internal street, the plan shows Pacific Sunset Maples and Chanticleer pears. The plan shows the street trees located in the right-of-way. The screening and buffering of the new development will be provided within the open space easements along the perimeter of the site. The plan indicates a mixture of native trees and shrubs creating a lush setting along Knaus and Goodall Roads. In addition, several mature trees along Knaus and Goodall Roads will be preserved. Staff notes the Landscape Plan does not coincide with the Open Space Plan (Exhibit E-5), which shows 40 feet of open space easement at the front of Lot 4 and 52.5 feet in front of Lots 2 and 3. Also, in front of Lots 11, 12, 13 and 14, the 25 feet of open space easement is not reflected on the Landscape Plan. As a condition of approval, the final landscape plan must coincide with the Open Space Plan. With regard to the plantings in the open space easements along the internal street, the landscape plan indicates triangular shaped areas that straddle two lots in eight areas and contain a total of 16 Laceleaf Japanese maples which were originally located adjacent to the existing house on the site and are being cultivated in a nursery, and will serve to visually unify the open space areas. Staff also notes that there is a grading cut (3:1 slope) along Knaus Road in front of Lots 4, 5 and 15 as a result of the public sidewalk matching the grade of the driving surface. Although the slope up to the subject site is steep, the alternative would be a 4-5 foot retaining wall along the street. Staffs concern is the tree roots of mature evergreen trees that will be preserved along Knaus Road in front of Lot 15. Although the grading is minimal as it approaches the trees, the applicant will be required to have a certified arborist on site at any time during excavation, trenching, grading, root pruning or other activity occurring within the tree protection zone, to ensure proper protection of all trees to remain. Per LOC 50.06.010.2, the applicant will be required to post a bond for 5% of the total landscaping cost to ensure survival of all landscape material for one 12 -month growing season from the date of installation. This will be made a condition of approval. Maintenance of private open space shall be the common responsibility of the homeowners, which may be exercised through a Homeowners Association. If not maintained in accordance with this section, the City of Lake Oswego may enforce the maintenance obligations against the association and lot owners as provided in the covenants. This will also be made a condition of approval. This standard can be met. Lighting [LOC 50.06.004.3] This standard prescribes equipment and lighting specifications for public and private streets, pathways, access ways, and parking lots. There is no existing street light at the intersection of Goodall and Knaus Roads. Street lights are required at street intersections for collector and local level roads. This development will create increased traffic, bike, and pedestrian trips at the intersection of Goodall and Knaus Roads, thus requiring this intersection to have a street light. The development will be required to install a street light at that intersection. In addition, street lighting will be required for the new intersections where the internal street connects to Goodall and Knaus Roads. As conditioned, this standard is met. LU 14-0031 Page 8 of 27 Hillside Protection [50.06.006.2] This standard applies to all development that includes hillsides or areas with erosion potential and requires that development on undisturbed slopes exceeding 20% grade be kept to a minimum. If the site contains areas over 20% slope, a slope analysis map is required. The purpose of this standard is to maintain slope/soil stability on adjacent properties and protect natural vegetation. On land with undisturbed slopes in excess of 12%, cuts and fills shall be regulated such that no more than 65% of area in undisturbed slopes of 20% to 50% shall be graded or stripped of vegetation. In addition, land over 50% undisturbed slope shall be developed only where density transfer is not feasible. The applicant has submitted a slope analysis map (Exhibit E-8), which was also submitted and reviewed during the first partition of the site (LU 13-0044). The majority of the site is in the range of 0-20% with small areas of slope in the 20-50% range in the vicinity of the existing home and at the far east of the site which also contains a very small area of 50% slope and some areas associated with the drainage swales along Knaus Road. The applicant states that these areas were previously disturbed by grading and terracing during development of the existing home and driveway (Exhibit F-1), which resulted in artificially created slopes in the 20- 30% range. Undisturbed slopes are defined as those that: Undisturbed Slopes: Slopes, or portions of slopes, that have not been previously altered from the natural topography for slope stability, i.e., re-contoured, graded, and/or terraced and the altered slope was either performed in accordance with or subsequently approved by a licensed geotechnical engineer, registered civil engineer experienced in soils engineering, or licensed engineering geologist. Undisturbed slopes consist of natural topography, vegetation, and soils. The topographic map of the site (Exhibit E-3) confirms that the natural topography is broken in this area. The Geotechnical Report (Exhibit F-3) states that although no undocumented fill was encountered in the test pits that were dug, it appears that fill was placed in this area. [Staff notes that this prior analysis was done by the previous applicant for the site. The Geotechnical report states that, in addition, undocumented fill was encountered and soils in this area are stable. This report is part of the previous file, LU 07-0063]. Because the land in slopes of 20-50% is defined as disturbed, LOC 50.05.006.2.d.4 does not apply. This standard is met. Drainage Standard for Major Developments, Partitions, Subdivisions, and Certain Structures [LOC 50.06.006.3.b] The determination of whether the drainage management measures comply with the requirements of this standard is under the authority of the City Engineer. This standard requires that new development shall be conducted in such a manner that alterations of drainage patterns do not affect other properties. All drainage systems shall include engineering design features to minimize pollutants such as oil, suspended solids, and other objectionable material in stormwater runoff. Sufficient stormwater detention shall also be provided. The Engineering staff has made the following findings and recommends the following conditions of approval: LU 14-0031 Page 9 of 27 The applicant has submitted a storm drainage report dated May 2, 2014 (Exhibit F-2), and a preliminary storm drain plan (Exhibit E-12). The proposed storm drainage facilities for managing the storm runoff from the proposed development will consist of the following: On-site Stormwater runoff from the future impervious areas on each lot will be retained by incorporating a rain garden for water quality treatment followed by a chamber system to infiltrate the runoff. Each system will contain a flow control structure to release emergency overflow into the public system. For the new internal public street, roadside swales/planters will be constructed using a Low Impact Development Approach (LIDA) design. The planters will be constructed adjacent to the new public street, and a storm pipe conveyance system will route the runoff to two individual chamber detention facilities on site. The Engineering staff notes that the City will maintain the conveyance pipes and catch basins that collect the runoff from the street; however, in this case, the swales/planters along the public internal street and detention facilities will be required to be maintained by the Homeowners Association (HOA). The applicant will be required to submit an Operations and Maintenance plan for the private on-site detention and roadside swale/planters and record a Declaration of Covenant for Operation and Maintenance of Surface Water Management Facilities. Off-site Street improvements along Goodall and Knaus Roads will include drainage swales adjacent to the street that will convey runoff into LIDA swales. The LIDA swales will be sized to treat all new impervious areas from the street improvements. Storm conveyance pipes will be required to collect runoff from the swales and direct the flow downstream into the existing drainage system. The drainage swales along Goodall and Knaus Roads will also fall under the maintenance responsibility of the HOA and shall be included in the Operations and Maintenance plan. Each future building permit application for the individual lots will be required to submit design calculations and a final drainage report based on the contributing roof area and impervious area of the proposed home on the lot. Alternative stormwater management facilities such drywells can also be proposed, subject to review and approval by the City Engineer. In addition, subsurface disposal systems are regulated under Department of Environmental Quality (DEQ) Underground Injection Control (UIC) program, and the design shall meet all applicable requirements if a UIC is installed for stormwater disposal. Emergency overflow runoff shall be directed to an approved point of disposal. Each lot shall have a stormwater lateral to connect the emergency overflows to the public conveyance system located in the street. The Engineering staff finds that the proposed drainage features are acceptable for complying with the provisions of this standard. As conditioned, this standard is met. Solar Access [LOC 50.06.007] This standard requires that 80 percent of the lots resulting from a subdivision must comply with the solar design standard. A minimum of 13 of the proposed lots must, therefore, comply with one of three alternatives: (a) the Basic Requirement; (b) the Protected Solar LU 14-0031 Page 10 of 27 Building Line Option; or (c) the Performance Option; or the applicant may show that a lot qualifies for an exemption or adjustment to the design standard per LOC 50.04.004.1. Basic Requirement: A lot complies with the Basic Requirement if it has a north -south dimension of at least 90 feet and has a front lot line that is oriented within 30 degrees of a true east -west axis. As shown on Exhibit E-4, this standard is met for all lots except Lots 1,2, 3, 6,7 and 10, because they do not have a north south dimension of at least 90 feet and/or a front lot line within 30 degrees of a true east/west axis. Protected Solar Building Line: As an alternative, the applicant can show that three of these lots meet the Protected Solar Building Line option, (because a minimum of 13 lots must meet one of the options). This option requires that there be at least 70 feet between the middle of the north -south lot dimension on the lot to the south and the Protected Solar Building Line on the lot; and at least 45 feet between the protected solar building line and the north edge of the building area of the lot. As indicated on Exhibit E-4, Lots 3, 6 and 10 can meet the Protected Solar Building Line option. This provides 13 solar lots or 80 %, in compliance with the standard. As a condition of approval, these lots must be identified as solar lots in a "Notice of Development Restriction" recorded with the partition plats. As conditioned, this standard can be met. In addition, all single-family detached structures in any zone are required to meet the Maximum Shade Point Height Standard [LOC 50.06.007.2.c], which minimizes shading on adjacent lots to the north. Compliance will be assured during building permit review. This standard is met. Utilities [LOC 50.06.008] The Engineering staff has reviewed the applicant's proposed utility plan and profiles (Exhibits E-11 through E-14), and finds that utilities are available or can be made available, as follows: Sanitary Sewer: Sewer service for this development will be obtained by extending a public sewer from an existing 8" line in Goodall Road, located approximately 220 feet south of Knaus Road. This development will be required to bring public sanitary sewer up Goodall Road to serve the development's northwest parcel (Lot 10 shown on Exhibit E-4), approximately 475 feet north of Knaus Road, and also up the new internal street to serve Lots 9-14. A public sewer main will also be required up Knaus Road and the eastern leg of the new internal street, in order to serve the remainder of the lots. Public sanitary sewers shall be located within the public street, and service laterals shall be provided directly to a lot, without crossing other lots with a private sewer easement. As conditioned, this standard is met. [Note: Per LOC 50.06.008.3.d, design shall take into account the capacity and grade to allow for desirable future extension beyond the development, and where required by the City Manager, extend to the upstream property line to allow for such future extensions. Engineering staff reviewed the upstream properties and finds that along Goodall Road, the northern boundary of the subject site is the City's Urban Services Boundary and city sewer would not be extended beyond this boundary line. For properties east of the subject site along Knaus Road; 13081 and 12912 Knaus Road; the City of Lake Oswego Wastewater LU 14-0031 Page 11 of 27 Master Plan, dated 2013, indicates sewer service will be obtained from a future sewer extension coming from the east along Knaus Road, from an existing manhole located approximately 330 feet east of the site]. Water and Hydrants: There is an existing 8" City water main located in Knaus Road. This project will require an 8" public water extension be brought up to the new internal street connection at Goodall Road, approximately 150 feet north of Knaus Road. An 8" public water main extension will be required within the internal public street to loop the public system between Goodall and Knaus Roads. A public extension will also be required up Goodall Road from where the new internal street will connect to Goodall Road, to serve the development's northwest parcel (Lot 10 shown on exhibit E-4). [Note: Per LOC 50.06.008.3.4, design shall take into account the capacity and grade to allow for desirable future extension beyond the development, and where required by the City Manager, extend to the upstream property line to allow for such future extensions. Engineering staff reviewed the upstream properties and finds that along Goodall Road, the northern boundary of the subject site is the City's Urban Services Boundary and city water would not be extended beyond this boundary line. There is an existing city water main located along the entire Knaus Road frontage.] A new fire hydrant(s) shall be installed on the internal street, as shown on Exhibit E-11, and as approved by the Fire Marshal (Exhibit F-9). As conditioned, this standard is met. Streets: Knaus and Goodall Roads are neighborhood collectors and are currently under the jurisdiction of Clackamas County along the site frontage. Details regarding road jurisdiction with Clackamas County are currently being reviewed between the county and the City of Lake Oswego, and the road transfer documents are currently being reviewed by the county. The northern approximate 150 lineal feet of the street frontage along Goodall Road is currently outside of the City of Lake Oswego's Urban Services Boundary. See comments below under LOC Chapter 42 for additional information regarding street improvements. Sidewalks: Asphalt pathways exist across the street from the site along Knaus Road. There are no existing sidewalks or pathways located along Goodall Road; however, there is an existing sidewalk located along the south side of Adrian Court across from the northwest corner of the site. An asphalt pathway also exists along the east side of Goodall Road south of Knaus Road. See comments below under Streets and Sidewalks LOC Chapter 42. Other utilities: It is the applicant's responsibility to ascertain the availability of electric, gas, telecommunications and cable TV. All new utilities shall be installed underground. Staff notes that it is not clear if franchise utilities will need to be located along the property frontage on Knaus Road. If needed they must be underground and located in a public utility easement. LU 14-0031 Page 12 of 27 4. Any additional statutory, regulatory or Lake Oswego Code provisions which may be applicable to the specific minor development application; City of Lake Oswego Streets and Sidewalks Chanter [LOC Chapter 421 Vision Clearance [LOC 42.03.1301 This standard requires that no vegetation, fence or signage higher than 30 inches be located within a "vision clearance triangle." The vision clearance triangles for a driveway are formed by 10 -foot legs extending from the intersection of the driveway and the street travel lane. No specific driveway approach locations are shown with the proposed development plans. As a condition of approval, at the time of building permit review, the proposed driveway approach location for each lot shall demonstrate compliance with this standard. As conditioned, this standard is met. With regard to the intersection of the new street with Knaus and Goodall Roads, the applicant has provided a Traffic Impact Study, Exhibit F-5, which includes a site distance analysis for these new intersections. The intersection of Highland Loop and Goodall Road meets AASHTO site distance requirements. Site distance for the Knaus Road intersection can be achieved by removing vegetation within the AASHTO site lines and constructed to allow the driver to be at the level of the roadway when positioned 15 feet back from the near side travel lane. Compliance will be assured during review of the construction documents. Street and Sidewalk Improvements [LOC 42.03.005 —.125] This Chapter authorizes the City Engineer to make specific street and sidewalk improvement recommendations after taking a variety of policy and site specific factors into consideration .3 The City Engineer's comments are included for review of the overall understanding of the project. The City Engineer's conditions of approval are included, as they must be included in the decision, to find that the application will comply with this article. The Engineering staff has reviewed the development proposal and field conditions in the context of the City's codes, improvement policies and Transportation System Plan (TSP), and offers the following findings and conditions of approval. The proposed development can be expected to contribute 10 vehicle trips to the City's street system per lot per average weekday.° Additional pedestrian and bicycle trips can be expected as well. The cumulative effect of new trips (all modes), imposes an additional burden and concomitant concerns for preserving street capacity and public safety, particularly for bicycles and pedestrians. Per LOC 50.07.003.5a.iii, conditions may be imposed to alleviate a need for public services or facilities created or contributed to by the 3 T meet the review criteria for a minor development, the applicant must comply with "any additional... Lake Oswego Code provisions which may be applicable to the specific minor development application, such as ... the Streets and Sidewalks Ordinance." LOC 50.07.003.14.d. The determination of whether or not the application meets the requirements of LOC Chapter 42, Streets and Sidewalks, is under the review authority of the City Manager or City Engineer, the requirements of this Chapter are not under the review authority of a hearing body, other than to find whether or not the City Engineer or City Manager has found that the application complies with LOC Chapter 42, or whether conditions of approval are required for compliance with this Chapter. Trip Generation (8" edition), Institute of Transportation Engineers LU 14-0031 Page 13 of 27 proposed development. "Public services or facilities" include streets, sidewalks and pathways. The City has a governmental interest in assuring that new development does not contribute to a degradation of adequate, safe and efficient public transportation facilities. New development should mitigate the negative impacts (increased noise, and the degradation of aesthetics, safety, system capacity, and bicycle and pedestrian mobility) resulting from new development. The City has adopted a broad array of policies, plans, regulations, and fees that have been designed to offset the adverse impacts of development on the natural and built environment. In this regard, the following regulations and standards reflect the governmental interest in preserving the functionality and safety of the public infrastructure, and are particularly relevant to this development proposal: • LOC Chapter 42 requires frontage improvements to be constructed when property is developed. • LOC Chapter 42 directs the City Engineer to recommend to the decision making authority the appropriate width of public rights of way, and the width and character of the improvements contained therein. • Where applicable, street frontage improvements, landscaping and pathway improvements shall comply with the City Engineer's policy memorandum, Guidelines and Standards for New Streets and Frontage Improvements in the Urbanizing Rural Fringe and Transition Neighborhoods, effective February 1, 2005. The implementation of the City's plans, policies, and regulations will offset to some degree the negative impacts of development on the public infrastructure. LOC 50.07.003.5 allows the reviewing authority to impose conditions of approval on a development permit when the condition is reasonably related to alleviation of a need for public services or facilities created or contributed to by the proposed development. In addition, the US Supreme Court has rule (Dolan v. City of Tigard) that, in order to require mitigation, the local government must apply a test of "rough proportionality" between the impacts of the proposed development and the need for the mitigation to offset impacts from the development. Goodall and Knaus Roads are designated as a "neighborhood collector" in the City's functional classification system. The City's Comprehensive Plan identifies Goodall Road south of Knaus Road as shared roadway bike route and in need of a pathway. Goodall Road is a direct route to Boones Ferry north of the site, thus also being a shared roadway. The Comprehensive Plan also identifies Knaus Road as a shared roadway. The existing pavement width along these roads is substandard for this designation. A standard engineering design of a shared lane is 14 feet wide. The existing pavement width varies along the site frontages of these two roads, but in some areas the entire roadway width is approximately 18 -feet wide, within a 40 -foot wide right-of-way. Goodall and Knaus Roads are also identified as a proposed "Community Connector Trail/Pathway" route in the Lake Oswego Trails and Pathways Master Plan. The Engineering staff has conducted further review of the frontage improvement requirements for this development. To alleviate to a degree a need for public services or facilities created or contributed to by the proposed development, based on an increase of 13 additional lots at ultimate build -out, the development will be required to dedicate sufficient right-of-way for required frontage improvements and construct half -street improvements along the entire site frontage of Goodall and Knaus Roads. [Note: right -of - LU 14-0031 Page 14 of 27 way dedication along Goodall and Knaus Roads was provided on the recorded partition plat per the prior land approval under LU 13-0044]. The required half -street section along Goodall and Knaus Roads shall consist of 14 -feet of pavement from the traveled centerline, a 3 -foot wide gravel shoulder, an 8 -foot wide drainage Swale, a 6 -foot wide asphalt pathway at the back of the right-of-way, and a one - foot level area between the back of the pathway and the right-of-way line. The existing overhead utilities along Goodall Road shall be installed underground along the site frontage and to ensure that it does not conflict with the landscaping in the open space easements along the perimeter, utilities may be required to be located in the right-of-way. Note: Street widening must follow the public notice and election requirements prescribed in Section 40 of the City Charter. A permit for road construction will not be issued until the Charter requirements have been met Sufficient right-of-way dedication shall also be provided for the new internal public street. The new public street shall be constructed to public standards and shall consist of the following design elements: • 55 -feet of dedicated right-of-way. • 26 -feet roadway width (face -of -curb to face -of -curb). • 5 -foot concrete sidewalk on one side of the street, located at the back of the right- of-way. On the sidewalk side, the improvements behind the curb shall consist of a 3 -foot level strip adjacent to the back of the curb, 8 -foot wide drainage swale/planter (or lawn where planters are not installed), one -foot wide level strip between the back of the swale/planter and sidewalk, a 5 -foot sidewalk and one foot level strip between the back of the sidewalk and right-of-way line. • On the non -sidewalk side of the street, the street shall be signed "no -parking." The improvements behind the curb shall consist of a one -foot level strip adjacent to the back of the curb, 8 -foot wide drainage swale/planter (or lawn where planters are not installed), and one -foot wide level strip between the back of the swale/planter and right-of-way line. • Standard concrete curb and gutter on both sides of the street. • A 10 -foot public utility easement (or less if acceptable to the franchise utility companies) along both sides of the street right-of-way for undergrounding the franchise utilities. The applicant also has provided a traffic report (Exhibit F-5), which addresses the capacity of the street system in the immediate area, including intersections that are impacted by the proposed development. All studied intersections are found to operate at acceptable levels of service. As a condition of approval of the proposed development, the City will require the following on-site and off-site construction of or improvements to public services or facilities to alleviate impacts created or increased by the proposed development: • Widen the pavement along the east side of Goodall Road and the north side of Knaus Road along the entire site frontage to achieve a 14 -foot wide shared travel lane (measured from the existing painted yellow centerline) and construct a minimum 3 -foot wide, compacted crushed rock shoulder. • Construct an 8 -foot wide drainage swale along the site frontage on Goodall and Knaus Roads. A culvert shall be provided at any pedestrian crossings where the pathway will LU 14-0031 Page 15 of 27 connect back to the edge of road, at any driveway approaches and at the new public street intersections. • Construct a 6 -foot wide asphalt pedestrian pathway behind the drainage swale along the entire site frontage on Goodall and Knaus Roads, with a connection back to the edge of the road at each end of the site. Grant a 10- foot public utility easement (or less if acceptable to the franchise utility companies) along the site frontage of Goodall Road for undergrounding the existing overhead utilities or franchise utilities, if necessary. Construct new internal public street serving the development to City standards as described, above. The Engineering staff notes that that final design elements related to the street design shall be to the satisfaction of the City Engineer. As a condition of approval, adjustments to the internal street profile and street grading design will be necessary in the final design, because the centerline profile along the east leg of the internal street shall be adjusted to allow surface run-off from the lots to drain to the curb. In addition, the eyebrow shall be designed to accommodate city operation maintenance vehicles and be designed to City standards. The City finds that the right-of-way dedication and public street improvements are therefore directly related to alleviating the increased traffic, bike, and pedestrian trips that will be created by this development. The City finds that requiring the right-of-way dedication and public street improvements is roughly proportional to the adverse impacts upon the public services and facilities created by the development because: • The development will generate 10 additional vehicle trips per additional lot per day using Goodall and Knaus Roads and the adjacent local street system. • The development will generate 10 vehicle trips per lot per day using the new internal street serving the development. • The additional site generated traffic creates an increased point of conflict between pedestrian and bicycles using the adjacent street system. By providing right-of-way dedication and public street improvements along the site frontage and through the development, the public safety will be maintained. • The new pathway along the site frontage and sidewalk along the new internal street will result in a greater use of alternative modes of travel (pedestrian, bicycle, transit), both today and in the future, as traffic congestion increases in the area. These additional alternative mode travel trips will offset the additional vehicle trips generated by the development. • Similar right-of-way dedications and public street improvements have been required for similar developments in the area, with the result being that such development conditions for street improvements have mitigated the increased traffic (vehicle, pedestrian bicycle) by preserving the functionality and public safety features of the public street system. In light of the above facts and Code requirements, staff finds that the development of this site will place sufficient additional demand on the local streets to justify the right-of-way dedication and street improvements at this time, and that the required dedication and street improvement requirements are roughly proportional to the degree of impact imposed by the new development, as described above, and consistent with the improvements of similar developments of land along Goodall and Knaus Roads, as LU 14-0031 Page 16 of 27 required by LOC 50.07.003.5 and the U.S. Supreme Court in the case of Dolan v. the City of Tigard. City of Lake Oswego Tree Chapter [LOC Chapter 551 This Code requires approval of a permit for removal of any tree in excess of 5 -inches in diameter, subject to Type II criteria as listed in LOC 55.02.080(1-4), and prescribes protection measures for trees to remain during construction. The tree removal plan (Exhibit E-15) indicates 20 trees that are invasive species and will be applied for under a separate permit. Compliance with LOC 55.02.080 is required for the removal of the other 27 trees shown on the tree removal plan. Any trees proposed for removal will be granted tree removal permits [LOC 55.02.035; 55.02.080], if they: • Must be removed for development or landscaping purposes; • Will not have a significant negative impact on erosion, soil stability, flow of surface waters, protection of adjacent trees, or existing windbreaks; • Will not have a significant negative impact on the character, aesthetics, or property values of the neighborhood, except when alternatives to tree removal have been considered and no reasonable alternative exists to allow the property to used as permitted in the zone; and, • The sole purpose is not for the purpose of providing or enhancing views. Regarding the removal of these trees, staff finds that: 1. The removal is for development purposes allowed pursuant to the City Code; The removal of the trees on the western and southern portion of the site is necessary for development because they are located within the area of required public improvements (construction of new streets and sidewalks), and grading. The trees proposed for removal on the eastern portion of the site are vulnerable because they have been topped and these are being removed for landscape purposes as indicated on the landscape plan (Exhibit E-6). This criterion is met. 2. The removal will not have a significant negative impact on erosion, soil stability, flow of surface waters, protection of adjacent trees, or existing windbreaks; The removal of non-invasive trees on the southern portion of the site will not have a significant negative impact on erosion, soil stability, or flow of surface waters because they are in the right-of-way where there is little slope or are located in areas where the site will be re -graded and developed with the internal street and stormwater facilities. Surface water flow will be contained as part of the street and stormwater facility design. Their removal does not have a significant negative impact on the protection of adjacent trees or existing windbreaks, because except for the three large pines that will be preserved in a cluster, all of the other trees in this area are being removed because they are invasive or for grading and utility location purposes. The non-invasive trees proposed for removal on the eastern portion of the site have been topped and are vulnerable. They would be more vulnerable once the invasive trees in that area are removed. The large pine and oak that will be preserved to the south of these trees will provide soil stability and windbreak. On the western portion of the site, the largest trees are not proposed for removal. They provide soil stability and windbreak and protect against erosion in this western portion of LU 14-0031 Page 17 of 27 the site; removal of the non-invasive trees as a part of this application will not negatively affect the existing soil stability and windbreak, nor promote erosion. 3. The removal will not have a significant negative impact on the character, aesthetics, or property values of the neighborhood, except when alternatives to tree removal have been considered and no reasonable alternative exists to allow the property to used as permitted in the zone; and The removal of 27 non-invasive trees will not have a negative impact on the character, aesthetics, or property values of the neighborhood, because the trees on the perimeter of the site are the dominant trees in the total streetscape of the neighborhood and the trees being removed are not dominant trees. This criterion is met. 4. The removal is not for the sole purpose of providing or enhancing views. The trees requested for removal are not being removed for view enhancement; they are being removed to construct public improvements and grading and landscaping to facilitate the serial partitions permitted by the Development Agreement. For the reasons outlined above, staff concludes that the removal of the 27 non-invasive trees complies with the applicable criteria and may be approved. The applicant shall apply for a verification tree removal permit for the 27 trees prior to approval of any construction plans. Mitigation Any tree approved for removal under the Type II tree analysis shall be mitigated at a minimum 1:1 ratio. Mitigation trees should have a minimum 2 -inch caliper diameter for deciduous trees and a minimum 6-8 foot height (excluding leader) for evergreen trees. Mitigation does not include street trees. The landscape plan (Exhibit E-6) indicates the correct amount of mitigation trees in the Open space Easements and on the eastern portion of the site. Tree Protection The Code requires tree protection measures when a tree protection zone or drip line of a tree is within the construction zone, whether on or off-site [LOC 55.08.030(1)]. Exhibit E-15 shows the trees that will be preserved and must be protected during construction. The protective fencing shall be placed at the tree protection zone, which is the zone required to protect the critical root area necessary for the continued health of the trees. The applicant should propose the tree protection zone for each tree, for review and approval by City staff, on site. As required by LOC 55.08.030(7), no construction, excavation, root pruning or other activity shall occur within the tree protection zone unless directed by an arborist present on site and approved by the City. A note should be placed on the construction documents that informs the site contractors about the necessity of preventing damage to these trees, including bark and root zone, and that no materials should be stored or compaction occur within the root zones of the adjacent trees [LOC 55.08.030). The contractor shall be subject to fines, penalties and mitigation for trees that are damaged or destroyed during construction. As a condition of approval, as required by LOC 55.08.02 and 55.08.030, a tree protection plan shall be submitted with the building permit plans for staff review and approval. Tree protection measures must be LU 14-0031 Page 18 of 27 installed prior to issuance of any grading or building permits. Tree protection fencing consists of 6 -foot high chain link fencing supported by 6 -foot high metal posts, placed a maximum of ten feet apart. 5. Any applicable condition of approval imposed pursuant to an approved ODPS or prior development permit affecting the subject property. There are no conditions of approval of prior City development permits affecting the site. The development is subject to the terms of the Agreement approved by LU 14-0021. VIII. CONCLUSION Based upon the materials submitted by the applicant and findings presented in this report, staff concludes that LU 14-0031 can be made to comply with all applicable criteria by the imposition of conditions. IX. RECOMMENDED ACTION Approval of LU 14-0031, subject to the following conditions: A. Prior to Submittal of any Partition Application Subsequent to this Approval. the Applicant/Owner Shall: Note: As provided for in the Development Agreement, building permits may be obtained to construct up to two single family dwellings per parcel (after the second (1014) partition is approved) prior to recordation of the third (2015) partition plat, as a means to facilitate construction in preparation for featuring the development as the 2015 Portland Homebuilder's Association "Street of Dreams," that will take place in the summer of 2015. However, the Development Agreement does not permit occupancy of any dwelling on these parcels until the 1015 partition plat is recorded and each dwelling is on its own lot. 1. Submit engineered construction plans for the public improvements along Goodall and Knaus Roads for review and approval by Clackamas County. The plans shall be designed to Clackamas County standards. 2. If prior to construction of the public improvements on Goodall and Knaus Roads, the design, maintenance and permitting authority for these roads have been transferred to the City of Lake Oswego, the applicant may request (as substantial conformance to the county requirements for street improvements) to construct to the City of Lake Oswego street standards, as provided below. In that event, the applicant shall submit construction drawings for the public and site improvements for review and approval by the City Engineer.

This narrative has been prepared in order to describe the proposed master plan and to document compliance with the applicable sections of Lake Oswego's Development Code. SITE DESCRIPTION/SURROUNDING LAND USE The subject site is 7.35 acres in size and is zoned R-7.5 (Low Density- 7,500 square feet area per unit). The site is generally grassy with trees around the perimeter of the property and surrounding the home. The site is not within the floodplain. The site has frontage on both Goodall Road and Knaus Road. The site is zoned R-7.5, as are the properties to the south across Knaus Road and the southwest across Goodall Road. Properties to the east and west are part of unincorporated Clackamas County. Properties to the north are in the City of Portland and/or Multnomah County. All surrounding properties are developed with single family homes with the exception of taxlot 501, which is vacant. SITE HISTORY This property was annexed to the City of Lake Oswego in 2005 via LU 05-008. In 2007 and 2008, a partition, master plan and development agreement were approved for the property. The land use approvals were never implemented. In 2013, a minor land partition (LU 13-0044) was approved for dividing the site into three (3) parcels. Subsequently, on April 24, 2013, a Development Agreement was submitted to the City of Lake Oswego for signature detailing the final build -out of the site (16 single-family lots) and the policies and procedures that will govern development of the site. This development site has been designated as the site of the 2015 Portland Homebuilders' Association "NW Natural Street of Dreams". The 16 lots proposed at final build -out will be developed with single- family homes including cutting-edge technology, high quality building materials, and expert craftsmanship techniques. PROPOSAL This is a proposal for approval of a Master Plan for a 7.05 acre site at the northeast corner of SW Goodall Road and 5W Knaus Road. This Master Plan serves to identify the development of the site through three partition applications (one submitted and approved in 2013 and two more to be submitted in each of the two following years, 2014 and 2015) and one right-of-way dedication by legal document. The land use submissions for the partitions will allow the three existing lots to be divided into three lots each, totaling 9 lots. The 9 lots created by the 2014 partitions will then be partitioned in 2015 to create the final 16 lot plan. THE HIGHLANDS I MASTER PLAN 13.1 CONSULTING, INC. 37 The purpose of the Master Plan is to obtain certainty for the City, the Developer and the adjacent property owners of the full build -out of 16 single-family detached residential lots on this site. The Master Plan includes such elements as street design (including access), landscaping and buffering, open space provision and tree preservation and mitigation. DEVELOPMENT AGREEMENT A Development Agreement was submitted to the City of Lake Oswego on April 24, 2014 for review and signature by the City. The Development Agreement identifies the development procedure of the site, the use of the site for single-family detached residential homes and specific design criteria such as architectural, illumination and parks and open space and infrastructure improvements. The City, the Applicant, and the Forest Highlands Neighborhood Association of Lake Oswego have worked together to create the development agreement forthe site and all parties are supportive of this plan, the agreement, and the land division process. Section 5 of the Development Agreement requires submittal of a Master Plan within 60 days of the approval of the Development Agreement. This submittal is the proposed Master Plan for this site, including: the approved partition in 2013 and the proposed partitions for calendar year 2014 and 2015; a final plan showing development at build out, including required public infrastructure; and a development schedule for review of building, grading and other permits.

The result shall be rounded up for any product with a fraction of 0.5 or greater and rounded down for any product with a fraction of less than 0.5. The requirements of this section are subject to the exceptions contained in LOC 50.04.003.10, Exceptions to the Minimum Density Requirement for All Zones. [2] Net developable footage divided by the minimum lot area per unit and rounded down to the nearest whole number. The actual density allowed on a site will be determined at the time of development review. Maximum density will be allowed to the extent that facts presented to the hearing body showthat development at that density can occur within requirements set forth in the Development Standards. [3] Up to a 25% reduction in minimum required lot area for each dwelling unit shall be allowed to permit the relocation of a designated historic landmark, when relocation has been approved by the designated hearing body. [4] Base building height of single-family dwellings may be increased by one ft. for every five additional ft. in yard setback on all sides. [5] Maximum base height across the site shall be established by a flat plane measured at 28 ft. (R-7.5 zone) or 30 ft. (R-10 zone) above the highest point of the natural grade within the building envelope, except that in no caseshall the base heightbe greater than 32 ft. (R-7.5 zone) or 34 ft.

The maximum density for the R-7.5 zone is 5 dwelling units per acre. The proposed development will result in 16 parcels on a 7.05 acres or 2.23 dwelling units per acre. This Master Plan application is preceded by one minor land partition approval (LU 13- 0044) and will be followed by two subsequent major land partitions (one in 2014 and one THE HIGHLANDS I MASTER PLAN 13.1 CONSULTING, INC. 42 in 2015). This was done to satisfy the neighbors' concerns regarding density and housing type and to provide larger lots for construction of the 2015 NW Natural Street of Dreams homes. Partitions are not subject to the minimum density requirement. All lots greatly exceed the minimum dimensional standards. Floor area, setback, height and lot coverage standards will be met as reviewed during building permit submittal. The requirements of this section have been satisfied. 50.04.002. SPECIAL STREET SETBACKS 1. PURPOSE To assure an adequate front yard setback is available in the event of possible future street improvements, such as additional lanes, pedestrian and bicycle facilities, transit facilities, drainage management improvements, lighting, and street landscaping. Applicant's Per Table 50.04.002-1, SW Knaus Road has a 30 -foot special street setback measured from Finding: the centerline of the existing right-of-way. The existing right-of-way along the site's southern frontage on SW Knaus Road is 40 feet total, 20 -feet from existing centerline. The applicant proposed via the previous minor land partition (LU 13-0044) to dedicate 11 feet of right-of-way and widen SW Knaus Road from the centerline north. Full build -out of the project will result in a 14 -foot wide pavement section from centerline, 3 -foot gravel transition area, 8 -foot drainage Swale and 6 -foot asphalt path, for a total right-of-way of 31 feet from centerline. Therefore, the special setback will be within the future right-of- way and no additional special setback is necessary on this property. The requirements of this section have been satisfied. LOC 50.06 DEVELOPMENT STANDARDS 50.06.001. BUILDING DESIGN 2. STRUCTURE DESIGN- RESIDENTIAL ZONES b. Street Front Setback Plane Except as set forth in LOC 50.06.001.2.d and for flag lots in the R-6 zone, the profile of a structure that fronts on a street shall fit behind a plane that starts at the setback line (front yard or side yard abutting a street) and extends upward to 20 ft. in height, then slopes toward the center of the lot up to the maximum base height of the zone, as illustrated below in Figure 50.06.001- A: Street Front and Street Side Setback Plane. The slope of the street front setback plane is dependent upon whether it applies to a front yard or side yard abutting a street, as follows: L Front yard — 6:12 slope, or ii. Side yard abutting a street — 12:12 slope. c. Street Front Setback Plane Exceptions L Roof Form THE HIGHLANDS I MASTER PLAN 13.1 CONSULTING, INC. 43 Any individual roof form may penetrate the street front setback plane if it is less than one third of the structure width, as illustrated in Figure 50.06.001-B: Exceptions to Street Front Setback Plane. Two or more separate and distinct roof forms, such as dormers, may project into the street front setback plane if they are less than one-half of the structure width. ii. Projections Any eaves, bay windows, chimneys and other decorative features, front porch, cornices, eaves, gutters, belt courses, leaders, sills, pilasters, lintels, ornamental features, and other architectural features, canopies, sunshades, chimneys, and flues that are allowed to project into the front yard setback shall fit below the extension of the street front setback plane, as illustratedin Figure .06.001-C. e. Side Yard Setback Plane — Interior Yards Except as set forth in subsection 2.e.ii of this section, the side profile of a structure shall fit behind a plane that starts at the side property line and extends upward to 12 ft. and slopes toward the center of the lot at a slope of 12:12 up to the maximum allowed height at the peak as illustrated in Figure 50.06.001-G: Side Yard Setback Plane. i. Roof forms may penetrate into the side yard setback plane required under (e), above, as follows: (1) Any individual roof form may penetrate the side setback plane if it is less than one- third of the structure length at 12 ft. in height. Two or more separate and distinct roof forms such as dormers or gables may project into the side setback plane if they are less than one-half of the structure length at 12 ft. in height. (2) Building projections allowed under LOC 50.04.003.8, General Exceptions for Building Projections, Decks, and Walkways and Pathways to Setbacks, may project up to two ft. into the side yard setback plane. Chimneys are exempt from the setback plane requirement. ii. On steeply sloped lots that are upslope from the abutting street, no side yard plane is required. f. Side Yard Appearance and Screening At least one of the following design treatments shall be applied along side yards or side elevations. This section is applicable to both interior side yards and side yards that abut streets. i. Treatment 1— Maximum Side Yard Plane (1) When the side elevation of a primary structure is more than 500 sq. ft. in area in an R-0, R-2, R-3, R-5, or R-6 zone ("Group 1") or more than 750 sq. ft. in area in an R-7.5, R- 10, or R-15 zone ("Group 2"), the elevation must be divided into distinct planes of 500 sq. ft. or less for Group for 750 sq. ft. or less for Group 2. For the purpose of this standard, areas of side yard wall planes that are entirely separated from other wall planes are those that result in a change in plane, such as a recessed or projecting section of the structure that projects or recedes at least two ft. from the adjacent plane, for a length of at least six ft. THE HIGHLANDS ( MASTER PLAN 1 3.1 CONSULTING, INC. 44 (2) Except in the R-0, R-2, R-3, and R-5 zones, the maximum side yard plane may be increased by 10% on a side for every additional five ft. of side yard setback provided beyond the minimum required by the zone, on the side property line. ii. Treatment 2 — Side Yard Features (1) The side elevation of a structure shall consist of two or more planes that are offset by a minimum of 16 in. The wall planes shall be a minimum of four ft. in width, and shall result in a change in a wail plane for one full story. Exception: Window bays may be utilized to satisfy the requirement for offsets. Such windows shall extend a minimum of 12 in. outward from the main wall of a building and shall form a functional bay or alcove in an interior room. Bay windows used to meet this requirement shall not be exempt from setback requirements. (2) Walls shall include a roof eave overhang of 16 in. or greater, and (3) Windows and/or doors shall occupy a minimum of 15% of the side elevation facing the street, and all windows shall have a window trim that is a minimum of four in. in width. iii. Treatment 3 — Screening The applicant shall provide screening and buffering of the wall plane with a minimum of one standard plant unit for every 50 linear ft. of side property line or fraction thereof. Planting shall occur within an area that is defined by the length of the side elevation plus 20 ft. beyond the width of the building at either end, and outward 20 ft. from the side elevation of the building, towards the side lot line, as shown in Figure 50.06.001-H: Screening and Buffering. Applicant's Per Section 2.4 of the Development Agreement (submitted to the City of Lake Oswego on Finding: April 24, 2014), the Developer will prepare and record architectural covenants that govern the exterior design of structures within the development. While this is not required by the Code, it is required within the development agreement it will give the City and neighboring property owners a guarantee that high-quality architectural features and materials for all permanent structures will be used and that all walls of residences facing public streets will incorporate windows. These architectural covenants will be in addition to the requirements imposed with this Section, which will also be implemented throughout the development. The requirements of this section have been satisfied. LOC 50.06.002 PARKING 2. STANDARDS FOR APPROVAL a. Vehicle Parking i. Required parking spaces shall be available for the parking of operable passenger vehicles of residents, customers, patrons and employees and shall not be used for the storage of vehicles or materials or for the loading and unloading or parking of vehicles used in conducting the business or use. ii.

Applicant's A minimum of 1 space per each of the three dwelling units will be provided; however, the Finding: homes will each have at least 2 off street parking spaces without including the garage. The requirements of this section have been satisfied. LOC 50.06.003 CIRCULATION AND CONNECTIVITY 1. ACCESS/ACCESS LANES (FLAG LATS) c. Standards for Approval L Every residentially zoned lot shall abut a street for the following minimum length: Rowhouse- 17 feet Flag Lot- LOC 50.07.007.2.c All Other- 25 feet ii. Access design shall be based on the following five criteria: (1) Topography; (2) Traffic volume to be generated by the development; (3) Classification of the public street from which the access is taken (residential, collector or arterial); (4) Traffic volume presently carried by such street; and (5) Projected traffic volumes. iii. Direct permanent access from a development to an arterial street is prohibited where an alternate access is either available or is expected to be available. A temporary access may be allowed. iv. Direct access from a development or a structure to a local residential street is required unless such access is not available. v. The City may require shared access with a neighboring site or an extension of residential streets across adjacent properties to provide access to the development if necessary to prevent adverse impacts on traffic flow. vi. If no satisfactory access from a public street to a development is available, the City shall require postponement of the development until such time as a satisfactory access becomes available. vii. Access lanes created by a partition or private streets created by a subdivision shall contemporaneously provide an option of dedication to the City. d. Standards for Access Lanes Access lanes shall meet the following minimum standards: i. Twenty -ft. wide easement. ii. Access to two to four dwelling units — 12 ft. of pavement with a four ft. shoulder on each side. iii. Access to five to eight dwelling units -- 16 ft. of pavement with a two ft. shoulder on each side. THE HIGHLANDS I MASTER PLAN 13.1 CONSULTING, INC. 46 iv. When providing access for seven to eight dwelling units, the access lane shall be designed to provide "on -lane" parking for a minimum of four standard vehicles or provide an "offlane" parking area for a minimum of four standard vehicles. e. Traffic Study Determination of the location and configuration of an access shall be based on a traffic study, unless otherwise approved by the City Manager. f.

Distance between Access and Nearest Intersection Access from a major development to a collector or an arterial shall be not less than 100 ft. from the nearest intersection of street centerlines. Applicant's All 16 tots at final build -out will have direct access with greater than 25 -feet of frontage Finding: on SW Goodall Road, SW Knaus Road or the new local internal street, Highland Loop. All lots are proposed for single-family development and no row houses or flag lots are proposed. Each driveway/access wH serve one dwelling unit. The requirements of this section have been satisfied. 2. ON-SITE CIRCULATION — DRIVEWAYS AND FIRE ACCESS ROADS b. Standards for Approval i. Driveway Approaches—Locational Limitations and Restrictions (1) On corner lots where the adjacent streets are fully improved to their anticipated ultimate width, the nearest edge of a proposed driveway to the intersection shall be no closer than 30 ft. when measured from the projected curb of the street that is the most parallel to the alignment of the proposed driveway. (2) On corner lots where the adjacent streets are not fully improved to their anticipated ulti- mate width, the nearest edge of a proposed driveway to the intersection shall be no closer than 30 ft. when measured from the lot corner, or if the corner is a radius, from the point of intersection of the tangents. If right-of-way dedication is required as a condition of approval, the lot lines after dedication shall be used as the basis for determining compliance with this standard. (3) On lots with less than 75 ft. of continuous frontage on a single public street, only one driveway shall be permitted along that frontage. (4) All driveway approaches shall be located and designed so that the driver entering or exiting the driveway can see approaching traffic for a sufficient distance to make a safe entrance and exit. American Association of State Highway and Transportation Officials (AASHTO) standards shall be used in determining compliance with this standard. (5) The maximum width of a driveway approach, measured where the edges of the drive- way meet the right-of-way, shall be governed as follows: (a) Single-family residential with garage door(s) facing the street: 12 ft. per garage or carport stall, or surface parking space, but not to exceed 30 ft. THE HIGHLANDS I MASTER PLAN I 3J CONSULTING, INC. 47 (b) Single-family residential with side -loading garage: 24 ft. (c) All other uses: 24 ft. unless otherwise justified by the recommendations of a traffic study. ii. Driveway Widths Driveways shall conform to the minimum width requirements of LOC 15.06.610 (Oregon Fire Code Adopted) and LOC 50.06.002, Parking. iii. Driveway Grades (1) The maximum grade of a driveway serving one single-family structure shall be 20%. If the grade exceeds 15%, then the residence must be provided with alternative methods for fire suppression, i.e., sprinklering. (2) The maximum grade of a driveway for all other uses shall be 15%. (3) For all uses except residential structures of four units or less, there shall be a landing area where a driveway used by multiple drivers meets the public street. The landing area shall be a minimum of 25 ft. long and shall have a maximum grade of 5%. The length and grade of the landing area described in this subsection presupposes that the abutting street has been fully improved to its ultimate anticipated width. If a driveway is pro- posed on a street that is not fully improved, and the development proposal is anticipated to proceed prior to the improvement of the street, the City Engineer shall determine the driveway and site grading so that this standard will not be compromised when the street is improved in the future. (4) Along the traveled way, grade breaks shall not exceed an algebraic difference of 9% unless accomplished by the construction of a vertical curve complying with the City's Standard Details. (5) The maximum cross -slope of a driveway shall be 5%, except for that portion of a drive- way which must blend with an adjacent street grade that exceeds 5%. When blending is necessary, the length of the blended section shall be limited to 30 ft. iv. Fire Access Lanes (1) All developments shall comply with the minimum requirements for fire access roads as stipulated by the Fire Code and LOC Chapter 15. (2) The paved improvement of fire lanes, their associated turnarounds and right-of-way dimensions shall comply with the City's Standard Details. (3) When a fire access road is required to be used as a primary or alternate access route for the provision of emergency services to or through an abutting property, the fire lane shall be declared as such on a legal instrument to be recorded against the title of the affected property(i es). A declaration on a plat or on a recorded development plan may also be used to satisfy this standard. Applicant's All sixteen lots at final build -out will have driveways that meet the driveway standards. Finding: All driveways will meet the standard of a maximum driveway grade of 15% with a maximum 5% cross slope. All driveway locations will provide safe and convenient access to the lots, meeting all standards, City and AA5HTO. All Fire Department standards will be met as shown on the attached plans. The requirements of this section have been satisfied. 4. LOCAL STREET CONNECTIVITY MMWTH HIGHLANDS I MASTER PLAN 13.1 CONSULTING, INC. 48 b. Purpose and intent The purpose of the connectivity standard is to ensure that: L The layout of the local street system does not create excessive travel lengths or limit route choices. This will be accomplished through an interconnected local street system to reduce travel distance, promote the use of alternative modes of travel, provide for efficient provision of utility and emergency services, provide for more even dispersal of traffic, and reduce air pollution and energy consumption; ii. Streets, alleys and residential accessways shall be designed to meet the needs of pedestrians and cyclists and encourage walking, bicycling and transit as transportation modes; iii.

This report will do the following: • Show compliance with all City of Lake Oswego drainage requirements and design criteria. • Provide factual data, field investigation reports, calculations, maps, drawings, cross- sections, analysis, and other information needed to support and verify the findings and conclusions of the drainage report. • Describe and show all existing on-site drainage conditions. • Describe and show all on-site and off-site adverse drainage impacts of proposed development. • Provide the conceptual drainage plan needed to mitigate the drainage impacts of the development. • Provide evidence (plans) that the proposed drainage system and facilities will meet required design criteria; will fit on the site; and will avoid, if possible, and minimize destruction or loss of natural resources. • Provide design criteria needed to prepare construction plans and specifications. PRO IECT OVERVIEW Project Description The site is located at 12800 Goodall Road in Lake Oswego on approximately 7.05 acres on tax lot 2sle4ba 00500 (See Technical Appendix: Exhibits — Figures 1 and 2). Additionally, tax lot 2s1e4ba 00501 to the northeast of the property is being included as future development for this project. The project site currently contains a private residence with an asphalt driveway and concrete parking area (See Technical Appendix: Drawings — Sheets 0100 & C101). The proposed project (including the future development) will create eighteen buildable lots with public roads and sidewalks and public street improvements to SW Goodall Road and SW Knaus Road (See Technical Appendix: Exhibits — Post Developed Site Conditions). Drainage Characteristics According to the Lake Oswego Drainage Basin Map, the project site is located within the Tryon Creek Basin in the Willamette River Watershed. Stormwater runoff from the western portion of the site drains south to southwest towards SW Goodall Road and SW Knaus Road. The runoff enters an existing drainage ditch that conveys water south via a 12 inch culvert under SW Knaus Road. Runoff draining to SW Knaus Road is conveyed west towards the culvert through ditches, catch basins and underground pipes. The culvert conveys runoff south along the east side of SW Goodall Road to a tributary of Tryon Creek. The eastern portion of the site drains to the south to a ditch along Knaus road where drainage is conveyed through a culvert under Knaus road, approximately mid -site and flows south through adjacent properties to a tributary of Tryon Creek. Flood Map The site and all adjacent properties are located within Zone X (un -shaded) per flood insurance rate map (FIRM) community -panel number 41005C0012D. FEMA's definition of Zone X (un- shaded) is an area of minimal flood hazard, usually depicted on firms as above the 500 -year flood level (See Technical Appendix: Exhibits —FIRM Panel 12 of 1175). 1 1 P a g e 67 The Highlands Storm Drainage Report Impervious Area Calculations Table 1 shows the current impervious and pervious areas for the property (See Technical Appendix: Exhibits — Existing Site Conditions). The existing site is approximately 4.4% impervious.

The proposed lots will vary between with the largest at 26,730 sf and the smallest at 11,340 sf. Stormwater from the impervious areas will not leave a lot unless the 50 year storm event is exceeded. To determine the required detention volume for the onsite public right-of-way (ROW), the existing area that the public ROW area encompasses was compared to the post -developed public ROW area plus the pervious portions of the lots (an assumption of 25% per lot was made). Table 2 below reflects post -developed pervious and impervious areas draining to the proposed detention facilities (See Technical Appendix: Exhibits — Onsite Post -Developed Public Right -of -Way).

According to Portland maps.com, the soils on the uphill properties are moderately well drained (See Technical Appendix: Exhibits — Figure 3). Therefore, it is assumed that stormwater runoff infiltrates into the soil (See Technical Appendix: Exhibits — Figure 4). Runoff from the uphill portion of SW Goodall Road sheet flows south into the existing drainage ditches along the road. This area is approximately 3,050 square feet. A small upstream basin (approximately 1,884 square feet) on SW Knaus Road consisting of asphalt drains towards the site into roadside vegetated areas. On -Site Drainage Characteristics The western portion of the site drains southwest into the existing ditches in SW Goodall and SW Knaus Road. The ditch conveys runoff to a 12 inch culvert crossing SW Knaus Road from SW Goodall Road. Runoff from the eastern portion of the site flows to the existing ditch on the north side of Knaus Road, which then is conveyed under SW Knaus Road through a culvert and then south. Site Geology The soil types as classified by the United States Department of Agriculture Soil Survey of Clackamas County are identified in Table 3 (See Technical Appendix: Exhibits — Hydrologic Soil Group — Clackamas County Area, Oregon). Soil Type Hydrologic Group Cascade Silt Loam C Cornelius Silt Loam C Table 3 - Soil Characteristics Group C soils have slow infiltration rates when thoroughly wet. They consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. Curve Number The major factors for determining the CN values are hydrologic soil group, cover type, treatment, hydrologic condition, and antecedent runoff condition. The curve number represents runoff potential from the ground. Tables 2-2a and 2-2c in the TR -55 manual were used to determine the appropriate curve numbers (See Technical Appendix: Exhibits — Table 2-2a and 2-2c Runoff Curve Numbers). The existing conditions of the property have been categorized as Meadow (continuous grass and protected from grazing but generally mowed for hay) with a corresponding curve number of 71. The post -developed site was considered Open space in poor condition (<50% grass cover) with a corresponding curve number of 98. Geotechnical Report A geotechnical report by Geotech Solutions was prepared for the previous submittal on the property, dated August 31, 2006. The report recommends an infiltration rate of 0.7 cubic inches per square inch (includes a factor of safety of 3) applied to the sides only of an infiltration facility. 31Page 69 The Highlands Storm Drainage Report Downhill Drainage Characteristics The two separate systems conveying runoff from the project site eventually join one unnamed creek downstream of the project site (See Technical Appendix: Figure 5 — Downhill Drainage). Runoff from the eastern portion of the project site draining to SW Knaus Road outfalls into a drainage ditch on Tax lot 2S1E4ba 601. The property owners at that location have voiced concerns about increasing the runoff to this ditch as they are in a low point and frequently are flooded. PR-OPOSED DRAI NAG ->r WNVEYANCE SYST-C—M5 On -Site Conveyance Stormwater runoff from the future impervious areas on each lot will be 100% retained for all storm events up to and including the 50 -year storm event. Each lot will incorporate a rain garden for water quality treatment followed by a StormTech Chamber system to fully retain and infiltrate the runoff. Each system will contain a flow control structure to release storm events beyond the 50 - year event into the public system. Two new public roads with sidewalks are proposed within the development. Roadside Low Impact Development Approach (LIDA) swales will be constructed adjacent to the new public roads to treat and infiltrate stormwater runoff from the new roads and sidewalks. The LIDA swales will convey stormwater beyond the water quality event to two separate StormTech Chamber detention facilities. The detention facilities have been sized to release stormwater during the 50 - year storm event at or less than the existing 10 -year storm event for the site. Off -Site Public Street Conveyance Street improvements to SW Goodall Road and SW Knaus Road will include drainage ditches flowing into LIDA swales. The LIDA swales have been sized to treat all new impervious area form the street improvements. The capacity of each system was modeled using the software XPSTORM and the 25 -year storm event. The following parameters were used to check the capacity of the proposed systems on SW Goodall Road and SW Knaus Road: • The Santa Barbara Unit Hydrograph with a Type 1A rainfall distribution and a total precipitation depth of 3.80 inches. • Time of Concentration: 5 minutes • Impervious Curve Number: 98 • Drainage Ditches: o Bottom width: 2' o Side Slopes: 3H:1V o Channel Slope: Varies o Manning's coefficient: 0.04 • LIDA Swales: o Bottom width: 2' o Side Slopes: 3H: IV o Channel Slope: Varies o Manning's coefficient: 0.24 System Capacities The proposed conveyance system was designed to convey and contain the peak runoff from a 25 -year design storm. Maximum flow in a storm drainage pipe occurs at approximately 0.94do (Depth of flow section (do) — depth of flow normal to the direction of flow). At 0.94do the section factor of uniform flow has a maximum value which results in optimum flow for a section without surcharge conditions. 4j Page 70 The Highlands Storm Drainage Report System Performance -Conveyance SW Goodall and SW Knaus Roads During a 25 -year storm event, the proposed conveyance systems will operate at or below 0.94do, (See Technical Appendix: XPSTORM Modeling - Conveyance Data). There will be no out of system flooding with at least 0.68 feet of freeboard for the conveyance system. Uphill Conveyance The drainage ditches that front the property on SW Goodall road will be improved to City standards. Stormwater runoff from the area north of the site will continue to flow into drainage ditches along SW Goodall Road. The new drainage ditch along SW Goodall Road has been sized to convey the runoff from the 25 -year storm event upstream basin. Downhill Conveyance The proposed onsite stormwater facilities for each lot will release stormwater only for storm events greater than the 50 -year event, which is greater than the current Lake Oswego requirements of releasing the 50 -year post developed event to the existing 10 -year event. The two proposed detention systems for the new onsite public streets and sidewalks will release the 50 -year storm event at less than the 10 -year existing storm event for the entire site. Therefore, it is anticipated that the downstream conveyance system will not observe any impacts. Sf&FRI CE WATERQ1AAL-ITY B.!CILITIES Water Quality Guidelines Water quality treatment for the proposed development was designed to meet the City of Lake Oswego's Surface Water Management Design Workbook, dated December 2003. Additionally, the proposed rain gardens and LIDA swales were designed following Clean Water Services (CWS) Low Impact Development Approaches Handbook dated July 2009. The City, as well as Clean Water Services, requires water quality facilities to remove 65 percent of the phosphorous from 100 percent of the newly constructed impervious areas. Using CWS LIDA Handbook for water quality treatment design, the facilities are presumed to remove 65 percent of the phosphorous from the newly constructed impervious areas. The City provides an exemption to the treatment requirement when the net increase from a proposed building is less than the equivalent of two single family dwellings, or 6,060 square feet. However, the proposed development has provided a design for rain gardens on each lot regardless of the exemption. Water Quality Facility Sizing Clean Water Services uses a sizing factor to design rain gardens and LIDA swales. The sizing factor for both is 0.06 times the new impervious area. Individual Lot: Rain Gardens Each lot will be constructed to suit the buyers' desires; therefore, it is not known what the proposed impervious areas will be per lot. Table 4 below shows a range of impervious areas and the required rain garden based on the 0.06 sizing factor. Each rain garden will be constructed with an overflow drain conveying stormwater to an underground retention facility (StormTech Chamber). 51Page 71 The Highlands Storm drainage Report Impervious Area Range Per Lot (sf) Top Surface Area Required for Rain Garden s 3,000 180 4,000 240 5,000 300 6,000 360 7,000 420 8,000 480 9,000 540 10,000 600 11,000 660 12,000 720 Table 4 — Rain Gardens Sizes Onsite Public Right -of -Way: LIDA Swales The two public streets within the development will be constructed with LIDA swales to treat and infiltrate runoff from the public right-of-way including streets and sidewalks. Sub -basins within this area were delineated to size the swales according to the amount of impervious area draining to them (See Technical Appendix: Exhibits — Onsite Post -Developed Public Right -of -Way). The new street running west to east contains a high point approximately 250 feet east of SW Goodall Road. Three sub -basins make up this area; however, the western most portion of the area cannot be captured by the onsite LIDA swales. This area (Basin 10) will flow west into the proposed LIDA swale on SW Knaus Road. East of the high point including the new cul-de-sac and new north to south street will continue draining to the south. Eight sub -basins make up this area; however, a portion of the southern part of the new north/south street will not be captured by the onsite LIDA swales. This area (Basin 11) will flow southwest into the LIDA swale proposed on SW Knaus Road. Table 5 below shows the sub -basin areas, where each will drain to, the calculated surface area of a LIDA swale and the proposed area provided.

As the surplus treatment area column shows, the surplus of treatment area will be 415 square feet. Offsite Public Right -of -Way: LIDA Swales Both SW Goodall Road and SW Knaus Road improvements will include street widening, sidewalks, conveyance ditches and LIDA swales. Two LIDA swales (Off-WQ#2 and #3) will be constructed on SW Goodall Road to treat the runoff from the new impervious area. Conveyance ditches will convey the runoff to the LIDA swales. Sub -basins within this area were delineated to size the swales according to the amount of impervious area draining to them (See Technical Appendix: Exhibits — Offsite Post -Developed Public Right -of -Way). Due to grading constraints, the sub -basin (Off -6) that is at the intersection of SW Goodall Road and SW Knaus Road will not be conveyed to a Swale. Overflow drains will be installed in each Swale. The two swales on SW Goodall Road will be hydraulically connected by a 12 inch pipe. The southernmost Swale will outfall into the Storm line leaving the proposed StormTech Chamber in the southwest corner of the site. SW Knaus Road contains a high point approximately 200 feet east of SW Goodall Road. One sub -basin makes up the western portion of the road that will be treated with a LIDA Swale (Off- WQ#3). The overflow drain in the Swale will convey flow to a new manhole proposed at the intersection of the two roads. Two sub -basins make up the eastern portion of the road that will be treated by two separate swales (Off-WQ#4 and #5). Each Swale will outfall into proposed storm lines conveying runoff to a proposed manhole near the intersection of SW Knaus Road the proposed street in the development.

STC>P-M WATTERRETENT(o CILITIES Individual Lot: Retention Sizing As stated previously, each lot will be constructed to suit the buyers' desires; therefore, it is not known what the proposed impervious area will be. StormTech Chambers have been sized in XPSTORM for impervious areas ranging from 3,000 to 12,000 square feet. The following parameters were used to size the proposed StormTech systems: • 50 -year Storm event with a precipitation depth of 4.30 inches • The Santa Barbara Unit Hydrograph with a Type 1A rainfall distribution • Time of Concentration: 5 minutes • Impervious Curve Number: 98 Table 7 below shows the required StormTech Chamber facilities and trench dimensions.

A time of concentration was calculated for the west and east basins and can be found in the Technical Appendix: Calculations — Time of Concentration. The following design criterion was used to calculate the runoff for the 10 -year existing and 50 -year post -developed runoff.- Existing unoff: Existing Time of Concentration: West Basin = 20 minutes, East Basin = 16 minutes • Existing Pervious Runoff Coefficient: 0.40 (Chart 10 - Lawns, Pasture and Meadows, slope 5% to 10% and Type C soils) 8j Page 74 The Highlands Storm Drainage Report Rost -Developed Pervious Runoff Coefficient: 0.40 (Chart 10 - Lawns, Pasture and Meadows, slope 5% to 10% and Type C soils) Impervious area Runoff Coefficient: 0.90 Assumed pervious area of each lot was 75% of total area Each facility was sized to release the 50 -year post -developed runoff to the existing 10 -year runoff. As noted previously, the area for the 10 -year existing runoff used the area the onsite public ROW encompasses, while the post -developed runoff used the onsite public ROW plus the pervious area from the lots (assuming 25% impervious). Table 8 shows the required detention volume and orifice sizing for each facility. Additionally, it shows that the release rate to the downstream storm systems will decrease considerably after development.

S WMM.4RY The City requires proposed sites to release the post -developed 50 -year runoff at the existing 10 - year runoff. The proposed storm system has been designed to release the post -developed 50 - year runoff less than the existing 10 -year runoff. Therefore, the proposed system will exceed the requirements of the City of Lake Oswego. 9 1 P a g e 75 The Highlands Storm Drainage Report TEC NCC,4LARpENDC Exhibits Figure 1 — Project Location Figure 2 — Vicinity Map Figure 3 — Uphill Property's Soil Classification - Figure 4 — Uphill Properties Figure 5 — Downhill Drainage FIRM Panel 12 of 1175 - Hydrologic Soil Group -Clackamas County Area, Oregon - Table 2-2a and 2-2c Runoff Curve Numbers - Existing Site Conditions - Onsite Post -Developed Public Right -of -Way - Offsite Post -Developed Public Right -of -Way - Post -Developed Site Conditions Drawings - Sheet C000 — Cover Sheet Sheets C100 & C101 — Existing Conditions Plan Sheets C200 & C201 — Grading and Erosion Control Plan Sheets C300 & C301 — Composite Utility Plan - Sheets C310 & C311 —Storm Drain Line `A' Plan & Profile Sheet C312 - Storm Drain Line `B' Plan & Profile Calculations - Time of Concentration Calculation - Existing West Basin Runoff - Existing East and NE Basin Runoff - Detention Sizing for SW Detention - StormTech Facility Sizing: The Highlands -West Basin - Detention Sizing for SE Detention - StormTech Facility Sizing: The Highlands -East Basin XPSTORM Modeling XPSTORM Hydraulic Layout— SW Goodall and SW Knaus Road (2 Pages) - XPSTORM Conveyance Data — SW Goodall and SW Knaus Road (1 Page) Excerpts from Clean Water Services LIDA Handbook - Infiltration Planter/Rain Garden (4 Pages) - LIDA Swale (4 Pages) Geotechnical Report - Report of Geotechnical Engineering Services by Geotech Solutions, Inc, August 31, 2006 REFERENCES 1.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (AID, BID, and CID). The groups are defined as follows: Group A. Sails having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission, Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (AID, B/D, or CID), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

Other assumptions are as follows: impervious areas are directly connected to the drainage system, impervious areas have a CN of 98, and pervious areas are considered equivalent to open space in good hydrologic condition. CN's for other combinations of conditions may be computed using figure 2-3 or 24. 3 CN's shown are equivalent to those of pasture. Composite CN's may be computed for other combinations of open space cover type. 4 Composite CN's for natural desert landscaping should be computed using figures 2-3 or 2-4 based on the impervious area percentage (CN = 98) and the pervious area CN. The pervious area CN's are assumed equivalent to desert shrub in poor hydrologic condition. s Composite CN's to use for the design of temporary measures during grading and construction should be computed using figure 2-3 or 2-4 based on the degree of development (impervious area percentage) and the CN's for the newly graded pervious areas.

Infiltration planters typically require less piping than flow-through planters and a smaller facility size than traditional swales where native soils allow for infiltration. Depending on the site, infiltration planters can vary in shape and construction, with or without walls to contain the facility, or formed as a shallow, basin -like depression. Application & limitations Page 1 of 4 ij parking areas & impermeable landscape r7 !IIlIIIIlIIIIIIlII permeable soils Infiltration planters should be integrated into the overall site design and may help fulfill the landscaping area requirement. Infiltration planters can be used to manage stormwater flowing from all types of impervious surfaces, from private property and within the public right-of-way. Check with the local jurisdiction if proposing to use infiltration planters in the public right-of-way. The size, depth, and use of infiltration planters are determined by the infiltration rates of the site's existing soils. lli11111111111111\\\\\\\\\\\\\\\�O Beaumont Village Lofts. NE Portland Low Impact Development Approaches Handbook July 2009 27 125 28 Infiltration Planter/Rain Garden Page 2of4 Design Factors Soil Suitability and Facility Sizing The size and depth of the infiltration planter will depend upon the infiltration rate of existing soils. A sizing factor of 0.06 assumes the site infiltration rate is less than 2 in/hr. For example, the size of an infiltration planter managing 1,500 square feet of total impervious area would be 90 square feet (1,500 x 0.06). Size may be decreased if: • Demonstrated infiltration rate is greater than 2 in/hr using ASTM D3395-09 method; or • Amended soil depth is increased Geometry/Slopes The shape may be circular, square, rectangular, etc. to suit the site design requirements. Regardless of the shape, a minimum planter width of 30 inches is needed to achieve sufficient time for treatment and avoid short- circuiting. Planters in a relatively flat landscaped open area should not slope more than 0.5% in any direction. Piping for Infiltration Planters Follow Plumbing Code requirements for piping that directs stormwater from impervious surfaces to planters. Stormwater may flow directly from the public street right-of-way or adjacent parking lot areas via curb openings. For infiltration planters with walls, install an overflow drain to allow not more than 6 inches of water to pond. Infiltration planters with side slopes, such as rain gardens, need an overflow drain to ensure no more than 6 inches of water will pond. On private property, follow Plumbing Code requirements for this overflow drain and piping, and direct excess stormwater to an approved disposal point as identified on permit drawings. Check with local jurisdiction or use Clean Water Services Design and Construction Standards for additional information on piping material for use in the public right-of-way. Setbacks Check with the local building department to confirm site-specific requirements. • Generally, a minimum setback of 10 feet from building structures is recommended. • Planters should not be located immediately upslope of building structures.

Portland Design Factors (continued) infiltration planter areas, except as necessary to construct the facility. Consider construction of infiltration planter areas before construction of other impervious surfaces to avoid unnecessary traffic loads. Soil Am ndmen M 1 h Amended soils with appropriate compost and sand provide numerous benefits: infiltration; detention; retention; better plant establishment and growth; reduced summer irrigation needs; reduced fertilizer need; increased physical/chemical/microbial pollution reduction; and, reduced erosion potential. Primary treatment will occur in the top 18 inches of the infiltration planter. Amended soil in the treatment area is composed of equal parts of organic compost, gravelly sand and topsoil. Compost is weed -free, decomposed, non -woody plant material; animal waste is not allowed. Check with the local jurisdiction or Clean Water Services for Seal of Testing Approval Program (STA) Compost provider. To avoid erosion, use approved erosion control BMPs for non-structural infiltration planters. Vegetation Planted vegetation helps to attenuate stormwater flows and break down pollutants by interactions with bacteria, fungi, and other organisms in the planter soil. Vegetation also traps sediments, reduces erosion, and limits the spread of weeds. Appropriate, carefully selected plantings enhance the aesthetic and habitat value. The entire water quality treatment area should be planted appropriately for the soil conditions. Walled infiltration run-on planters will be inundated periodically, Therefore the entire planter should be planted with syr CleanVVate�`� Serveces New Seasons, 20th and SE Division St., Portland herbaceous rushes, sedges, perennials, ferns and shrubs that are well-suited to wet -to -moist soil conditions. If the infiltration planter has side slopes (basin without vertical walls), soil conditions will vary from wet to relatively dry; several planting zones should be considered.The flat bottom area will be moist -to -wet, and the side slopes will vary from moist at the bottom to relatively dry near the top where inundation rarely occurs.The moisture gradient will depend upon the designed maximum water depth, total depth of the planter, and steepness of the side slopes. This moisture gradient is a transition zone and should be planted with species that tolerate occasional standing water, and plants that prefer drier conditions toward the top of the slope. Areas above the side slopes, immediately adjacent to the basin, and above the designed high water line will not be inundated and should be planted with self-sustaining, low maintenance grasses, perennials, and shrubs suitable for the local climate. All vegetation should be planted densely and evenly to ensure proper hydrological function of the infiltration planter. Quantities per 100 square feet: • 115 herbaceous plants, 1' on center spacing, Y2 -gal container size; or 100 herbaceous plants, l' on center, and 4 shrubs, 1 -gal container size 2' on center. Trees are optional; if used, minimum 2 gallon by 2 feet tall. Trees are allowed in infiltration planters and should be selected by their adaptability to wet -to -moist conditions and full size at maturity. An area twice the width of tree rootball and the depth of the rootball plus 12" (or total depth of 30", whichever is greater) should be backfilled with amended soil for optimal growth, with no sub -surface rock layer. For infiltration planters with side slopes, trees should be placed along the side slopes of the facility rather than at the bottom.

The densely planted LIDA swale filters stormwater as it flows the length of the Swale and allows infiltration of water into the ground.The LIDA swale discharges to a storm sewer or other approved discharge point. Compared to vegetated swales, LIDA swales may be shorter and narrower, but require deeper levels of amended soil and a subsurface drain rock layer to compensate for the smaller size and to function effectively.

For sites with steeper slopes, check dams may be incorporated into the design. Side slopes from the bottom to the top of the swale must be 3:1 or less. The minimum bottom width is 2 feet, and the minimum depth is 1 foot. Piping for LIDA Swales If needed, stormwater may be directed from impervious surfaces to LIDA swales by piping per plumbing code requirements, or may flow directly into the LIDA swale via curb openings. A LIDA swale has no underdrain. An overflow drain allows no more 6 inches of water depth to collect in the LIDA swale. On private property, the overflow drain and piping must meet plumbing code requirements and direct excess stormwater to an approved disposal point.

Primary treatment will occur in the top 18 inches of the LIDA Swale. Amended soil in the treatment area is composed of imported soil, mix of one part organic compost, one part gravelly sand, and one part top soil. Compost is weed -free, decomposed, non -woody plant material; animal waste is not allowed. Reduce water velocities and potential erosion by providing energy dissipaters such as river rock at entrances to the swale.

SITE OBSERVATIONS AND CONDITIONS Surface Conditions The approximate 7.4 -acre parcel is located at the northeast corner of Goodall Road and SW Knaus Road at 12800 Goodall Road in Lake Oswego, Oregon. The site Is bound by Goodall Road to the west, Knaus Load to the south, and developed residential property on the north, and east. The site is currently occupied by a single residence. The site slopes moderately down to the southwest, south, and southeast from the highest elevation where the house is situated along the north central area of the property. The site is covered predominantly with grass. Several trees and blackberry vines line the perimeter of the property, most of which are depicted on the attached Site Plan. Subsurface Conditions General . We completed our explorations and infiltration testing on August 18, 7006 by excavating 6 test pits to depths of up to 10 feet below the existing ground surface (bgs) using a small track -mounted excavator. Approximate exploration locations are shown on the attached Site Plan. In general, subsurface conditions consist of silt with trace organics (topsoilitill zone) over stiff to very stiff brown silt containing trace to some sand and trace clar. Approximately 4 feet of silt rill containing concrete rubble, plastic pipe, and gravel was encountered in TP -5 at the edge of the existing western lawn area Specific subsurface conditions observed at each test pit exploration are described in the attached Test Pit logs. Our explorations encountered a heavy root tone that was approxlmately 8 inches thick A topsoil zone of 12 to 15 inches thick containing trace amounts of organics was encountered in several explorations. Laboratory testing resulted in moisture contents ranged from 14 to 30 percent. Groundwater - Groundwater seepage was not observed in our explorations. Irrfiltration Testing - Open hole infiltration testing was completed in test pit TP- I at depths of 14 feet, Test results Indicate that infiltration rates in the native silt is tow. CONCLUSIONS AND RECOMMENDATIONS General Based on the results of our explorations and analyses, the site development is feasible following the recommendations contained herein. The site soils consist of fine-grained slit which is easily disturbed when wet. If utility, earthwork, and foundation construction are planned for all but the driest late summer conditions, measures should be taken to minimize disturbance. ,217 1 i 12 71" Street Oregon City, OR 97045 p 503.657.3487 (Sa3.722.9946 136 377 August 31, 2006 renaissance -06-01-0 Earthwork Preparation - Prior to earthwork construction, the site should be prepared by completely removing existing structures, foundations, utilities, debris, and any uncontrolled fill. Site preparation for earthwork will also require removal of the root zone and topsoil from all pavement, building, and fill areas, and a 5 -foot perimeter around those areas, Any excavation resulting from the aforementioned preparation should be brought back to grade with structural fill. Disturbed surficial fill mixed with debris was observed at the ground surface in the vicinity of the demolished structures and should be removed. The heavy root zone encountered in our exploratlon ranged in thickness from 6 to 10 inches. Thicker stripping depths may be necessary in areas of tall grass, weeds, and brush. The thickness of the topsoil observed in our explorations was approximately 12 inches. We should be contacted to evaluate site preparation including removal of the existing undocumented fill and topsoil during earthwork construction. The topsoil layer should be completely removed from building, road, and fill areas. Root balls from trees may extend several feet and grubbing operations can cause considerable subgrade disturbance. AH disturbed material should be removed to undisturbed subgrade and backfilled with structural fill. In general, roots greater than one -inch in diameter should be removed. The test pit excavations were backfilled using relatively minimal cornpactive effort and soft spots can be expected at these locations. We recommend that these relatively uncompacted soils be removed from the test pits locates within the proposed building and paved areas to a depth of 3.0 feet below finished subgrade. The resulting excavation should be brought back to grade with structural fill. if located beneath a footing, the uncompacted soils should be completely removed and replaced with structural fill. Stabilization and Soft Areas - After stripping, we should be contacted to evaluate the exposed subgrade. This evaluation can be done by proof rolling in dry conditions or probing during wet conditions. Soft areas will require overexcavation and backfilling with well graded, angular crushed rock compacted as structural fill. A geosynthetic may also be required. We recommend that a geosynthetic used for stabilization consist of a woven geosynthetic with an AOS of 970 to # 140 sieve, and a minimum puncture resistance of 120 pounds (such as an AMOCO 2019 or equivalent). Working Blankets and Natal Roads- Construction equipment should not operate directly on the subgrade when wet, as it is susceptible to disturbance and softening. Rock working blankets and haul roads placed over a geosynthetic In a thickened advancing pad can be used to protect subgrades. We recommend that sound, angular, pit run or crushed basalt with no more than 6 percent passing a 4200 sieve be used to construct haul roads and working blankets. Working blankets should be at least 12 inches thick, and haul roads at least 24 inches thick. Alternatively, the soils could be cement amended to a depth of 12 Inches and covered with 4 Inches of crushed rock. Some repair of working blankets and 'haul roads should be expected. The above rock thicknesses are the minimum recommended. Subgrade protection is the responsibility of the contractor and thicker sections may be required based on subgrade conditions and type and frequency of construction equipment. 317 1112 r Street, Oregon Gty, OR 47015 p 503.657.3457 f 503.722.9946 378 137 August 31, 2006 renaissanc"6-01,e Slopes - All permanent and temporary cut slopes should be excavated with a smooth bucket excavator with the surface repaired if disturbed. In addition, upslope surface runoff should be rerouted so that it does not run down the face of the slopes. Equipment should not be allowed to induce vibration or infiltrate water above the slopes, and no surcharges are alloyed within 20 feet of the slope crest Permanent cut slopes up to 10 feet high can be inclined at 2H:IV In the medium stiff or better silt The presence of slow seepage may require installing a pit run rock blanket or a suitably revegetated reinforced erosion control blanket (such as North American Green SC 150 or equivalent). The presence of faster seepage may require additional erosion control measures, such as additional dtalnage elements, and/or flatter slopes, and we should be consulted Exposed soils which are soft or loose may also require such measures, fill slopes should be inclined no steeper than 2H:I V for slopes up to 10 feet high, and should be benched into existing slopes that are steeper than 5H:1 V. The face of the fill slope should be cut bark Into compacted materials with a smooth bucket excavator. If steeper fill slopes are desired, we should be consulted m evaluate use of amended soils or grid reinforcement. Erosion control is critical to maintaining fill slopes, and should be as described for cut slopes. FIJI - The on-site soil, excluding topsoil, can be used for m uctural fill if properly moisture conditioned. This will not be feasible during wet conditions. This can typically be accomplished In dry summer conditions where the soils will require drying by scarification and frequent mixing in thin lifts. Once moisture contents are within 3 percent of optimum, the material should be compacted to at least 92 percent relative to ASTM D-1557 (modified proctor) using a tamping foot type compactor. Fillshould be placed in lifts no greater than 10 inches in loose thickness. In addition to meeting density specifications, fill will also need to pass a proof roll using a loaded dump truck, water truck, or similar size equipment. In wet conditions; fill should be imported granular soil with less than 6 percent fines, such as clean crushed or pit run rock This material should be compacted to 95 percent relative to ASTM D-1557. Trenches - Utility trenches may encounter groundwater seepage and caving should be expected where seepage Is present Shoring of utility trenches will be required for depths greater than 4 feet and/or where groundwater seepage is present We recommend that the type and design of the shoring system be the responsibility of the contractor, who is in the best position to choose a system that fits the overall plan of operation. Pipe bedding should be installed in accordance with the pipe manufacturers' recommendations if groundwater is present in the base of the udlity trench excavation, we recommend overexcavating the trench by 12 to 18 inches and placing trench stabilization material in the base Trench stabilization material should consist of well -graded, crushed rock or crushed gravel with a maximum particle sde of 4 inches and free of deleterious materials. The percent passing the U.S. Standard #200 Sieve shall be less than 5 percent by weight when tested in accordance with ASTM C 117, Trench backfill above the pipe zone should consist of well graded, angular crushed rock or sand fill with no more than 7 percent passing a #200 sieve. Trench backfill should be compacted to 92 percent relative to ASTM D-1557, and construction of hard surfaces, such as sidewalks or pavement, should not occur within one week of backfilling. 417 1112 7' Street Oregon Gly, OR 97045 p503.657.3487 f503,722,9946 138 379 August 31, 2006 Residential Foundations renolssance-06-01-gi The undisturbed native silt or properly installed structural fill are suitable for residential foundation support Foundations must be embedded at least 18 inches below the lowest adjacent exterior grade. For sloping lots, footings should be embedded such that the downslope edge of footings are located a minimum of 10 from the face of the slope. The perimeter ground surface must be sloped to drain away from the foundations. Cut or fill slopes on lots need to comply with the Slopes section of this report. Perimeter foundation drains are required and should be constructed In accordance with the Ground Moisture section of this report. If footing construction is to occur in wet conditions, a few inches of crushed rock should be placed at the base of footings to reduce subgrade disturbance and softening during construction. Ground Moisture General - The perimeter ground surface and hand-scaping must be sloped to drain away from all structures. Gutters must be tight -lined to a suitable discharge and maintained as free-flowing. All crawl spaces must be adequately ventilated and sloped to drain to a suitable discharge. . Perimeter Foundation Drains - Perimeter foundation drains must be Installed around all exterior foundations. The foundation drains should consist of a two -foot wide zone of drain rock encompassing a 4 -Inch diameter perforated pipe, all enclosed with a non -woven filter fabric. The drain rock should have no more than 2 percent passing a 4200 sieve and should extend to within one foot of the ground surface. The geosynthetic should have an AOS of a #70 sieve, a minimum permittivity of 1.0 sec-}, and a minimum puncture resistance of 80 pounds (such as an AMOCO 1551 or equivalent). One foot of low permeability soil (such as the on-site silt) should be placed over the fabric at the top of the drain to isolate the drain from surface runoff. Foundation drains must be routed to a suitable discharge. Vapor Flaw Retardant - A continuous, impervious vapor flow retardant must be installed over the ground surface in the crawl space of all residential structures constructed at the site. Vapor flow retardants must be installed per the manufacturer's recommendations. Pavement Design The pavement subgrade should be prepared in accordance with the Earthwork recommendations presented in this report. All pavement subgrades will need to pass a proofroll prior to paving. Soft areas should be repaired by overexcavating the areas, installing a stabilization geosynthetic, and brought to -grade with well graded angular crushed rock compacted as structural fill. For a stabilisation geosynthetic we recommend a woven geosynthetic with an AOS of #70 to #100 slave, and a minimum puncture resistance of 120 pounds (such as an AMOCO 3019 or equivalent). We have developed pavement thickness at the site for 2, S, and 10 trucks per day (with a truck factor 0.6) and a 20 -year design life. These volumes can be revised if specific traffic data is available. Our analyses are based on AASHTO methods and subgrade of structural fill or undisturbed medium stiff silt or better, having a resilient modulus of 6,000 psi_ We have also assumed that pavement construction w411 be completed during an extended period of dry weather. Construction during wet conditions will likely require protection and stabilization of subgrades as recommended in the Stabilization and Sof;` Ureas and Working Blankets and Haut Roads sections of this report. The results of our analyses based on these parameters are provided in the following table. sn 1112 r Street, Oregon City, OR 47043 p 303.637.3487 )f 503.722.9946 380 139 August 31, 2006 renalwance-06-01-gf Trucks I Day ESAIL`s Asphalt Concrete Crushed Rock ; Inches inches 2 13,0 ! 7 3 6 5 32542 3 $ 1 b5,084 3 9 The thicknesses listed in the table above are intended to the minimum acceptable. Crushed rock should conform to ODOT base rock standards and have less than 6 percent passing the #200 sieve. Asphalt concrete should be compacted in one lift to 91 percent of a Rice Density, or to 98 percent of the maximum density from a test strip. 5torsmwater Infiltration Testing for Design - Open -hole, falling -head Infiltration testing was completed at a depth of 10 feet over an approximate 2.3 -ft by 2.5 fit area. Following saturation, the hole was filled with water to an approximate 12 inches of head. The water level dropped approximately 1.5 inches over a 25 minute period. Design - Based on the results of our testing and analyses site infiltration rates are low. We recommend using a design infiltration rate of 0.7 cubic inches per hour per square inch (this includes a reduction factor of 3 applied to test results) applied on to the sides of the system to account for long term siltation. The aforementioned depths are relative to existing (pre -construction) grades. Confirmation Testing - As actual subsurface conditions and infiltratlort can vary widely, testing of infiltration systems is required to confirm this preliminary estimate. Flexibility for adaptation of Infiltration systems should be planned into the design and construction, with contingencies built into the budgets and schedules. Infiltration systems need to be maintained free of debris and silt in order to function properly. (LIMITATIONS AND OBSERVATION DURING CONSTRUCTION We have prepared this report for use by Renaissance Homes and the design and construction teams for this project only. The information herein could be used for bidding or estimating purposes but should not be construed as a warranty of subsurface conditions. We have made observations only at the aforementioned locations and only to the stated depths. These observations do not reflect soil types, strata thicknesses, water levels or seepage that may exist between observations. We should be consulted to observe all foundation bearing surfaces, installation of structural fill, and subsurface drainage. We should be consulted to review final design and specifications in order to see that our recommendations are suitably followed. If any changes are made to the anticipated locations, loads, configurations, or construction timing, our recommendations may not be applicable, and we should be consulted. The preceding recommendations should be considered preliminary, as actual soil conditions may vary. In order for our recommendations to be final, we must be retained to observe actual subsurface conditions encountered. Our observations will allow us to interpret actual conditions and adapt our recommendations if needed. 617 1112 7' 5tme, Oregon C* OR 97045 p503.657-3487 f501722.9946 140 381 Augost 3 f, 2006 renaissance-06.01-gi Within the limitations of scope, schedule and budget, our services have been executed in accordance with the generaily accepted practices in this area at the time this report was prepared.

(GeoPacific) for the above referenced project (herein referred to as the "site"). The purpose of this study was to evaluate subsurface conditions at the site and to provide geotechnical recommendations for site grading, foundation design, and construction. This geotechnical study was performed in accordance with GeoPacific Proposal No. P4575, dated July 18, 2013, and your subsequent authorization of our agreement and General Conditions far Geotechnical Services. SITE DESCRIPTION AND PROPOSED DEVELOPMENT The site is approximately 7.35 acres in size and located northeast of the intersection of SW Goodall Road and SW Knaus Road in the City of Lake Oswego, Clackamas County, Oregon (Figure 1). Topography is predominantly gently to moderately sloping to the south with grades of about 5 to 20 percent. Some localized steeper slopes are present adjacent to the house and driveway- Vegetation consists primarily of short grasses with landscaping and sparse trees. The site currently includes one home. It is our understanding that the proposed subdivision is to include approximately 20 lots for single family homes, with associated streets, water quality facilities, and associated underground utilities. The preliminary grading plan indicates cuts and fills will be on the order of up to 8 feet. REGIONAL AND LOCAL GEOLOGIC SETTING Regionally, the subject site lies within the Willamette Valley/Puget Sound lowland, a broad structural depression situated between the Coast Range on the west and the Cascade Range on the east. A series of discontinuous faults subdivide the Willamette Valley into a mosaic of fault -bounded, structural blocks (Yeats et al., 1996). Uplifted structural blocks form bedrock highlands, while down -warped structural blocks form sedimentary basins. 14835 SW 72"° Avenue Portland, Oregon 97224 Tel (503) 598-8445 F EXHIBIT F-4 147 iu 14-0031 September 3, 2013 GeoPacific Project No. 13-3096 The subject site is underlain by Quaternary age (last 1.6 million years) loess, a windblown silt deposit that mantles older deposits, basalt bedrock, and elevated areas in the Portland region (Beeson et al., 1989; Madin, 1990). The loess generally consists of massive silt deposited following repeated catastrophic flooding events in the Willamette Valley, the last of which occurred about 10,000 years ago. In localized areas, the loess includes buried paleosols that developed between depositional events. Regionally, the total thickness of loess ranges from 5 feet to greater than 100 feet. Published regional geologic mapping indicates that the subject site is underlain by the Boring Lava lithologic unit which consists of basaltic and basaltic andesite lava flows erupted from a series of local volcanic vents during Plio-Pleistocene time (about 600,000 thousand to 2.6 million years ago) (Schlicker and Finlayson, 1979; Madin, 1990). Commonly these lava flows are interfingered with lenses and cones of volcanic ejecta commonly known as cinders or scoria. The total thickness of the Boring Lava unit ranges from greater than 600 feet near vents to less than 50 feet on the outer margins. At least three major source zones capable of generating damaging earthquakes are thought to exist in the vicinity of the subject site. These include the Portland Hills Fault Zone, the Gales Greek Newberg -Mt. Angel Structural Zone, and the Cascadia Subduction Zone. Portland Hills Fault Zone The Portland Hills Fault Zone is a series of NW -trending faults that include the central Portland Hills Fault, the western Oatfield Fault, and the eastern East Bank Fault. These faults occur in a northwest -trending zone that varies in width between 3.5 and 5.0 mules. The combined three faults vertically displace the Columbia River Basalt by 1,130 feet and appear to control thickness changes in late Pleistocene (approx. 780,000 years) sediment (Madin, 1990). The Portland Hills Fault occurs along the Willamette River at the base of the Portland Hills, and is about 3 miles northeast of the site. The Oatfield Fault occurs along the western side of the Portland Hills, and is about 1 mile northeast of the site. The Oatfield Fault is considered to be potentially seismogenic (Wong, et al., 2000). Madin and Mabey (1996) indicate the Portland Hills Fault Zone has experienced Late Quaternary (last 780,000 years) fault movement; however, movement has not been detected in the last 20,000 years. The accuracy of the fault mapping is stated to be within 500 meters (Wong, et al., 2000). No historical seismicity is correlated with the mapped portion of the Portland Hills Fault Zone, but in 1991 a M3.5 earthquake occurred on a NW -trending shear plane located 1.3 miles east of the fault (Yelin, 1992). Although there is no definitive evidence of recent activity, the Portland Hills Fault Zone is assumed to be potentially active (Geomatrix Consultants, 1995). Gales Creek-Newber -Mt. Angel Structural Zone The Gales Creek -Newberg -Mt. Angel Structural Zone is a 50 -mile -long zone of discontinuous, NW -trending faults that lies about 18 miles southwest of the subject site. These faults are recognized in the subsurface by vertical separation of the Columbia River Basalt and offset seismic reflectors in the overlying basin sediment (Yeats et al., 1996; Werner et al., 1992). A geologic reconnaissance and photogeologic analysis study conducted for the Scoggins Dam site in the Tualatin Basin revealed no evidence of deformed geomorphic surfaces along the structural zone (Unruh et al., 1994). No seismicity has been recorded on the Gales Creek or Newberg Fault (the fault closest to the subject site); however, these faults are considered to be potentially active because they may connect with the seismically active Mount Angel Fault and the rupture plane of the 1993 M5.6 Scotts Mills earthquake (Werner et al. 1992; Geomatrix Consultants, 1995). Cascadia Subduction Zone The Cascadia Subduction Zone is a 680 -mile -long zone of active tectonic convergence where oceanic crust of the Juan de Fuca Plate is subducting beneath the North American continent at a rate of 4 cm per year 13 -3096 -Highlands Property GR 2 GEOPACEFic ENGINEERING, INC. 148 September 3, 2013 GeoPacific Project No. 13-3096 (Goldfinger et al., 1996). A growing body of geologic evidence suggests that prehistoric subduction zone earthquakes have occurred (Atwater, 1992; Carver, 1992; Peterson et al., 1993; Geomatrix Consultants, 1995). This evidence includes: (1) buried tidal marshes recording episodic, sudden subsidence along the coast of northern California, Oregon, and Washington, (2) burial of subsided tidal marshes by tsunami wave deposits, (3) paleoliquefaction features, and (4) geodetic uplift patterns on the Oregon coast. Radiocarbon dates on buried tidal marshes indicate a recurrence interval for major subduction zone earthquakes of 250 to 650 years with the last event occurring 300 years ago (Atwater, 1992; Carver, 1992; Peterson et al., 1993; Geomatrix Consultants, 1995). The inferred seismogenic portion of the plate interface lies roughly along the Oregon Coast at depths of 20 and 40 kilometers below the ocean surface. FIELD EXPLORATION The site-specific exploration for this study was conducted on August 16, 2013 and consisted of exploratory test pits. Ten test pits, designated TP -1 through TP -10, were excavated with a medium sized backhoe to depths of approximately 3 to 10 feet, at approximate locations shown on Figure 2. It should be noted that exploration locations were determined in the field by pacing or taping distances from apparent property corners and other site features shown on the plans provided. As such, the locations of the explorations should be considered approximate. At the completion of the test pit logging, the test pits were backfilled with the excavated spoils and tamped with the backhoe bucket. This backfill should not be expected to behave as compacted structural fill and some minor settling of the ground surface may occur. Explorations were conducted under the full-time observation of GeoPacific personnel. Soil samples were classified in the field and representative portions were placed in relatively air -tight plastic bags. These soil samples were then returned to the laboratory for further examination and laboratory testing. Pertinent information including soil sample depths, stratigraphy, soil engineering characteristics, and groundwater occurrence was recorded. Soils were classified in general accordance with the Unified Soil Classification System. Summary test pit logs are attached. The stratigraphic contacts shown on the individual logs represent the approximate boundaries between soil types. The actual transitions may be more gradual. The soil and groundwater conditions depicted are only for the specific dates and locations reported, and therefore, are not necessarily representative of other locations and times. SUBSURFACE CONDITIONS The following discussion is a summary of subsurface conditions encountered in the test pit explorations. For more detailed information regarding subsurface conditions at specific exploration locations, refer to the attached test pit logs. Also, please note that subsurface conditions can vary between exploration locations, as discussed in the Uncertainty and Limitations section below. Soils On-site soils are anticipated to consist of topsoil, loess, and residual soil as described below. Undocumented Fill Undocumented fill was not encountered in our test pits; however, it is our understanding that fill was placed to the west of the existing home (see Figure 2). The fill material was from the excavation of the current home and is estimated to be approximately 1 foot in thickness. Other areas of minor localized old fill zones may be present in the vicinity of the existing structures, driveway, or in other areas beyond the test pit locations. 13 -3095 -Highlands Property GR 3 GEOPACIFIc ENGINEERING, INC. 149 September 3, 2013 GeoPacific Project No. 13-3096 Topsoil T In test pits TP -1 through TP -10, the ground surface was directly underlain by a topsoil horizon. These soils generally consisted of brown, low to moderately organic silt (ML -OL) that extended to a depth of about 6 to 9 inches below the ground surface. Loess -- Underlying the topsoil horizon in test pits was windblown loess. These soils were typically stiff to very stiff, light brown, silt (ML) with subtle to strong orange and gray mottling. In test pits TP -1 through TP -6 and TP -10, the loess extended to a depth of 7.5 to 8.5 feet. Loess extended beyond the maximum depth of exploration (9 feet) in test pits TP -7 through TP -9. Residual Soil — Underlying the loess in test pits TP -7 through TP -9 was residual soil derived from in place weathering of the underlying Boring Lava Formation. These soils were typically stiff to very stiff, light reddish brown, clayey silt (ML) to silty CLAY (CL) with trace black staining. In test pits TP -7 through TP -9, the residual soil extended beyond the maximum depth of exploration (10 feet). Groundwater During the field exploration, no groundwater or seepage was encountered to a depth of about 10 feet. Perched groundwater conditions often occur over fine-grained native deposits such as those beneath the site, particularly during the wet season. It is anticipated that groundwater conditions will vary depending on the season, local subsurface conditions, changes in site utilization, and other factors. INFILTRATION TESTING Soil infiltration testing was performed using the open hole infiltration method in test pits TP -1 through TP -4. Soil in borings was pre -saturated for a period of over 4 hours. The water level was measured to the nearest tenth of an inch every half hour with reference to the ground surface. Table 1 presents the results of our falling head infiltration tests. Table 1.

The following report sections present conclusions and recommendations regarding site preparation, engineered fill, wet weather earthwork, structural foundations, footing drains, seismic design, excavating conditions and trench backfill, pavement sections, and erosion control considerations. The recommendations of this report assume that the structures will have raised floors and crawlspaces. If structures are planned with basements 13 -3096 -Highlands Property GR 4 GEOPACIFIC ENGINEERING, INC. 150 September 3, 2013 GeoPacific Project No, 13-3096 or concrete slab -on -grade floors, GeoPacific should be contacted for additional recommendations regarding basement retaining wall design and drainage, concrete floor slabs and moisture protection, or other issues. Site PrMra+don and Undocumented Fill Removal Proposed areas to receive engineered fill should first be cleared of vegetation and any loose debris or undocumented fill, and debris from clearing should be removed from the site. Fill is present to the west of the existing home (see Figure 2), and may be present in other areas of the site as well. Organic -rich topsoil should be stripped to the relatively inorganic native soils. We anticipate that the depth of stripping will be an average of roughly 6 to 9 inches over most of the site. Deeper stripping will be needed in areas that have abundant root balls (where dense trees are present), been tilled in the past, or areas of localized fill deposits, etc. The final depth of stripping removal may vary depending on local subsurface conditions and the contractor's methods, and should be determined on the basis of a site inspection after the initial stripping has been performed. Stripped organic soil should be stockpiled only in designated areas or removed from the site and stripping operations should be observed and documented by GeoPacific. Any existing subsurface structures (tile drains, old utility lines, septic leach fields, etc.) beneath structures and pavements should be removed and the excavations backfilled with engineered fill. During dry weather conditions, once stripping is approved, the area should be ripped or tilled to a depth of 12 inches, moisture conditioned, and compacted in-place prior to the placement of engineered fill or crushed aggregate base for pavement. Exposed subgrade soils should be evaluated by GeoPacific. For large areas, and during wet weather, this evaluation is normally performed by proof -rolling the exposed subgrade with a fully loaded scraper or dump truck. For smaller areas where access is restricted, the subgrade should be evaluated by probing the soil with a steel probe. Soft/loose soils identified during subgrade preparation should be compacted to a firm and unyielding condition or over -excavated and replaced with engineered fill, as described below. The depth of overexcavation, if required, should be evaluated by GeoPacific at the time of construction. Enzineered Fill On-site native soils are anticipated to be suitable for use as engineered fill during dry weather, provided they are adequately moisture conditioned prior to compacting. Imported fill material should be reviewed by the geotechnical engineer prior to being imported to the site. Oversize material greater than 6 inches in size should not be used within 3 feet of foundation footings, and material greater than 12 inches in diameter should not be used in engineered fill. Engineered fill should be compacted in horizontal lifts not exceeding 12 inches using heavy vibratory compaction equipment. We recommend that engineered fill be compacted to at least 90% of the maximum dry density determined by Modified Proctor (ASTM D1557) or equivalent. We anticipate that aeration of native soil will be necessary for compaction operations. Proper test frequency and earthwork documentation usually requires daily observation and testing during stripping, rough grading, and placement of engineered fill. Field density testing should conform to ASTM D2922 and D3017, or D 1556. Engineered fill should be periodically observed and tested by GeoPacific. Typically, one density test is performed for at least every 2 vertical feet of fill placed or every 500 yd3, whichever requires more testing. Because testing is performed on an on-call basis, we recommend that the earthwork contractor be held contractually responsible for test scheduling and frequency. 13 -3096 -Highlands Property GR GEOPACIFIC ENGINEERING, INC. 151 September 3, 2013 GeoPacific Project No. 13-3096 Wet Weather Earthwork The on-site soils are moisture sensitive and may be difficult to handle or traverse with construction equipment during periods of wet weather. Earthwork is typically most economical when performed under dry weather conditions. Earthwork performed during the wet -weather season will probably require expensive measures such as cement treatment or imported granular material to compact fill to the recommended engineering specifications. If earthwork is to be performed or fill is to be placed in wet weather or under wet conditions when soil moisture content is difficult to control, the following recommendations should be incorporated into the contract specifications. • Farthwork should be performed in small areas to minimize exposure to wet weather. Excavation or the removal of unsuitable soils should be followed promptly by the placement and compaction of clean engineered fill. The size and type of construction equipment used may have to be limited to prevent soil disturbance. Under some circumstances, it may be necessary to excavate soils with a backhoe to minimize subgrade disturbance caused by equipment traffic; • The ground surface within the construction area should be graded to promote run-off of surface water and to prevent the ponding of water, • Material used as engineered fill should consist of clean, granular soil containing less than about 7 percent fines. The fines should be non -plastic. Alternatively, cement treatment of on-site soils may be performed to facilitate wet weather placement; • The ground surface within the construction area should be sealed by a smooth drum vibratory roller, or equivalent, and under no circumstances should be left uncompacted and exposed to moisture. Soils which become too wet for compaction should be removed and replaced with clean granular materials; • Excavation and placement of fill should be observed by the geotechnical engineer to verify that all unsuitable materials are removed and suitable compaction and site drainage is achieved; and • Bales of straw and/or geotextile silt fences should be strategically located to control erosion. If cement or time treatment is used to facilitate wet weather construction, GeoPacific should be contacted to provide additional recommendations and field monitoring. Structural Foundations Assuming our recommendations for site preparation are followed, native deposits and/or engineered fill soils will be encountered at or near the foundation level of the proposed structures. Native soils underlying the site are generally stiff to very stiff and should provide adequate support of the structural loads. Shallow, conventional isolated or continuous spread footings may be used to support the proposed structures, provided they are founded on competent native soils or compacted engineered fill placed directly upon the competent native soils. We recommend a maximum allowable bearing pressure of 2,000 pounds per square foot (psf) for designing the footings. The recommended maximum allowable bearing pressure may be increased by 1/3 for short term transient conditions such as wind and seismic loading. Footings should be embedded at least 12 inches below the lowest adjacent finished grade. Minimum footing widths should be determined by the project engineer/architect in accordance with applicable design codes. Assuming construction is accomplished as recommended herein, and for the foundation loads anticipated, we estimate total settlement of spread foundations of less than about 1 inch and differential settlement between two adjacent load-bearing components supported on competent soil of less than about '/a inch. We anticipate that the majority of the estimated settlement will occur during construction as loads are applied. 13 -31396 -Highlands Property GEL 6 GEOPACIFIC ENGINEERING, INC. 152 September 3, 2013 GeoPacific Project No. 13-3096 Wind, earthquakes, and unbalanced earth loads will subject the proposed structure to lateral forces. Lateral forces on a structure will be resisted by a combination of sliding resistance of its base or footing on the underlying soil and passive earth pressure against the buried portions of the structure. For use in design, a coefficient of friction of 0.45 may be assumed along the interface between the base of the footing and subgrade soils with no factor of safety included. Passive earth pressure for buried portions of structures may be calculated using an equivalent fluid weight of 330 pounds per cubic foot (pef), assuming footings are cast against dense, natural soils or engineered fill. The recommended coefficient of friction and passive earth pressure values do not include a safety factor. The upper 12 inches of soil should be neglected in passive pressure computations unless it is protected by pavement or slabs on grade. Footing excavations should be trimmed neat and the bottom of the excavation should be carefully prepared. Loose, wet or otherwise softened soil should be removed from the footing excavation prior to placing reinforcing steel bars. The above foundation recommendations are for dry weather conditions. Due to the high moisture sensitivity of on-site soils, construction during wet weather may require overexcavation of footings and backfill with compacted, crushed aggregate. Footing and Roof Drains We understand that the proposed homes will be raised floor, and that no concrete slab -on -grade floors will be used in living areas. Based on experience with standard local construction practices, perimeter footing drains are not required for raised wood floors with crawlspaces. However, if perimeter footing drains are not utilized, then positive exterior drainage away from the foundation, positive crawlspace drainage to an adequate low -point drain exiting the foundation, visqueen covering the exposed ground in the crawlspace, and crawlspace ventilation (foundation vents) become even more important. The homebuyers should be informed and educated that some slow flowing water in the crawlspaces is considered normal and not necessarily detrimental to the home given these other design elements incorporated into its construction. Evaluation of the potential for mold to develop in crawl spaces is beyond our area of expertise. If it is desired to reduce the potential for moist crawl spaces, footing drains may be installed. Where used, the outside edge of all perimeter footings should be provided with a drainage system consisting of minimum 3 -inch diameter, perforated plastic pipe embedded in a minimum of 1 W per lineal foot of clean crushed drain rock or 1'/z"- %" drain rock. The drain pipe and surrounding drain rock should be wrapped in non- woven geotextile (Mirafi 140N, or approved equivalent) to minimize the potential for clogging and/or ground loss due to piping. Water collected from the footing drains should be directed into the local storm drain system or other suitable outlet. A minimum 0.5 percent fall should be maintained throughout the drain and non -perforated pipe outlet. Down spouts and roof drains should not be connected to the foundation drains in order to reduce the potential for clogging. The footing drains should include clean -outs to allow periodic maintenance and inspection. Grades around the proposed structure should be sloped such that surface water drains away from the building. 13 -3096 -Highlands Property GR 7 GEOPACIFIc ENGINEERING, INC. 153 September 3, 2013 GeoPacific Project No. 13-3096 Seismic Design Structures should be designed to resist earthquake loading in accordance with the methodology described in the 2006 International Residential Code (IRC) for One- and Two -Family Dwellings, with applicable Oregon Structural Specialty Code (OSSC) revisions. We recommend Site Class D be used for design per the OSSC, Table 1613.5.2. Design values determined for the site using the USGS (United States Geological Survey) Earthquake Ground Motion Parameters utility are summarized in Table 2. Table 2. Recommended Earthquake Ground Motion Parameters (2006 IRC) Parameter Value _ Location (Lat, Lon ), degrees 45.432,-122.696 Ma ed Spectral Acceleration Values (MCE): Short Period, Ss 0.96 1.0 Sec Period, S, 0.34 Soil Factors for Site Class D: g, 1.11 F„ 1.72 Residential Site Value = 213 x F,, x S, 0.72 Residential Seismic Design Category Dl Soil liquefaction is a phenomenon wherein saturated soil deposits temporarily Iose strength and behave as a liquid in response to earthquake shaking. Soil liquefaction is generally limited to loose, granular soils located below the water table. Following development, on-site soils will consist predominantly of engineered fill or native fine-grained soils, which are not considered susceptible to liquefaction. Therefore, it is our opinion that special design or construction measures are not required to mitigate the effects of liquefaction. Excavating Conditions and Utility Trenches We anticipate that on-site soils can be excavated using conventional heavy equipment such as scrapers and trackhoes to a depth of 12 feet. Maintenance of safe working conditions, including temporary excavation stability, is the responsibility of the contractor. Actual slope inclinations at the time of construction should be determined based on safety requirements and actual soil and groundwater conditions. All temporary cuts in excess of 4 feet in height should be sloped in accordance with U.S. Occupational Safety and Heath Administration (OSHA) regulations (29 CFR Part 1.926), or be shored. The existing native soils classify as Type B Soil and temporary excavation side slope inclinations as steep as 1H:1 V may be assumed for planning purposes. This cut slope inclination is applicable to excavations above the water table only. Perched groundwater is likely to be encountered during wet weather season and should be anticipated in excavations and utility trenches. Vibrations created by traffic and construction equipment may cause some caving and raveling of excavation walls. In such an event, lateral support for the excavation walls should be provided by the contractor to prevent loss of ground support and possible distress to existing or previously constructed structural improvements. PVC pipe should be installed in accordance with the procedures specified in ASTM D2321. We recommend that structural trench backfill be compacted to at least 90% of the maximum dry density obtained by 13 -3096 -Highlands Property GR 8 GaEQPACIFIc ENGINEERING, INC. 154 September 3, 2013 GeoPacific Project No. 13-3096 Modified Proctor (ASTM D1557) or equivalent. Initial backfill lift thicknesses for a 3/"-0 crushed aggregate base may need to be as great as 4 feet to reduce the risk of flattening underlying flexible pipe. Subsequent lift thickness should not exceed I foot. If imported granular fill material is used, then the lifts for large vibrating plate -compaction equipment (e.g. hoe compactor attachments) may be up to 2 feet, provided that proper compaction is being achieved and each lift is tested. Use of large vibrating compaction equipment should be carefully monitored near existing structures and improvements due to the potential for vibration - induced damage. Adequate density testing should be performed during construction to verify that the recommended relative compaction is achieved. Typically, at least one density test is taken for every 4 vertical feet of backfill on each 200 -lineal -foot section of trench. Pavement Sections — On -Site Residential Streets Table 3 presents recommended minimum pavement section for on-site residential streets, under dry weather construction conditions. A subgrade soil R -value of 15 was assumed for design purposes. The recommended pavement sections were formulated using the Crushed Base Equivalent method and assuming a Traffic Index of 4 for on-site streets_ The Traffic Index is generally appropriate for minor residential streets and cul-de-sacs. The project engineer or architect should review the assumed traffic indices to evaluate their suitability for this project. Changes in anticipated traffic levels will affect the corresponding pavement section. Table 3. Recommended Minimum Dry Weather Pavement Sections Material Layer Y Minimum Thickness (inches) Compaction Standard Streets 92% of Rice Density (top lift) Asphaltic Concrete (AC) 3 91 % of Rice Density (lower lifts) AASHTO T-209 Crushed Aggregate Base 2 95% of Modified Proctor 3/"-0 (leveling course) ASTM D1557 Crushed Aggregate Base $ 95% of Modified Proctor 11/2"-0 ASTM D1557 Recommended Subgrade 12 90% of Modified Proctor or approved native In new pavement areas, native soil subgrade in pavement areas should be ripped or tilled to a minimum depth of 12 inches, moisture conditioned, and recompacted in-place to at least 90 percent of ASTM Di 557 (Modified Proctor) or equivalent. In order to verify subgrade strength, we recommend proof -rolling directly on subgrade with a loaded dump truck during dry weather and on top of base course in wet weather. Soft areas that pump, rut, or weave should be stabilized prior to paving. If pavement areas are to be constructed during wet weather, GeoPacific should review subgrade at the time of construction so that condition specific recommendations can be provided. Wet weather pavement construction is likely to require soil amendment or geotextile fabric and an increase in base course thickness. During placement of pavement section materials, density testing should be performed to verify compliance with project specifications. Generally, one subgrade, one base course, and one AC compaction test is performed for every 100 to 200 linear feet of paving. 13 -3096 -Highlands Property GR 9 GEoPACIFIC ENGINEERING, INC. 155 September 3, 2013 GeoPacifzc Project No. 13-3096 Erosion Control Considerations During our field exploration program, we did not observe soil types that would be considered highly susceptible to erosion. In our opinion, the primary concern regarding erosion potential will occur during construction, in areas that have been stripped of vegetation. Erosion at the site during construction can be minimized by implementing the project erosion control plan, which should include judicious use of straw bales and silt fences. If used, these erosion control devices should be in place and remain in place throughout site preparation and construction. Erosion and sedimentation of exposed soils can also be mininvzed by quickly re -vegetating exposed areas of soil, and by staging construction such that large areas of the project site are not denuded and exposed at the same time. Areas of exposed soil requiring immediate and/or temporary protection against exposure should be covered with either mulch or erosion control nettingfblankets. Areas of exposed soil requiring permanent stabilization should be seeded with an approved grass seed mixture, or hydroseeded with an approved seed - mulch -fertilizer mixture. UNCERTAINTIES AND LIMITATIONS We have prepared this report for the owner and their consultants for use in design of this project only. This report should be provided in its entirety to prospective contractors for bidding and estimating purposes; however, the conclusions and interpretations presented in this report should not be construed as a warranty of the subsurface conditions. Experience has shown that soil and groundwater conditions can vary significantly over small distances. If, during future site operations, subsurface conditions are encountered which vary appreciably from those described herein, GeoPacifzc should be notified for review of the recommendations of this report, and revision of such if necessary. Sufficient geotechnical monitoring, testing and consultation should be provided during construction to confirm that the conditions encountered are consistent with those indicated by explorations. The checklist attached to this report outlines recommended geotechnical observations and testing for the project. Recommendations for design changes will be provided should conditions revealed during construction differ from those anticipated, and to verify that the geotechnical aspects of construction comply with the contract plans and specifications. Within the limitations of scope, schedule and budget, GeoPaeific executed these services in accordance with generally accepted professional principles and practices in the field of geotechnical engineering at the time the report was prepared. No warranty, expressed or implied, is made. The scope of our work did not include environmental assessments or evaluations regarding the presence or absence of wetlands or hazardous or toxic substances in the soil, surface water, or groundwater at this site. 13 -3496 -Highlands Property GR 10 GEOPACIFIC ENGINEERING, INC. 156 September 3, 2013 GeoPacific Project No. 13-3096 We appreciate this opportunity to be of service.

A 16 -lot subdivision has been proposed for the property located at 12800 Goodall Road in Lake Oswego, Oregon. The site is located on the northeast corner of the intersection of Knaus Road at Goodall Road. 2. The subdivision of 16 residential lots will consist of single-family dwellings. These residences are expected to generate 12 trips during the morning peak hour and 16 trips during the evening peak hour. 3. Left -turn lane warrants were examined for the intersection of SW Boones Ferry Road at SW 19"' Avenue and were found to be met under existing conditions. Due to low volumes on minor streets, traffic signal warrants are not projected to be met at any time during development. No mitigations in relation to the proposed development are recommended. 4. Sight distance was measured at the location of the western property access to Goodall Road and found to meet both the intersection sight distance standards for the posted speed limit as well as the stopping sight distance standards for the 85`s -percentile speeds observed for traffic approach- ing the access from the north. Sight distance for the southern property access to Knaus Road was measured assuming that the vegetation along the property frontage will be cleared and that the access will be constructed to allow the driver to be at an elevation snatching the roadway when positioned t5 feet back from the traveled way. With these assumptions, it was found that sight distance would be sufficient to meet both the intersection sight distance standards for the posted speed limit as well as stopping sight distance standards for the 85`h -percentile speeds observed for traffic approach from either direction. 6. A detailed review of the crash history at each of the study intersections shows no trends that are indicative of safety issues that need to be addressed. No safety mitigations are recommended. 7. Each of the study area intersections are projected to operate within the performance standards set by the City of Lake Oswego under 2016 traffic conditions, regardless of the additional trips from the proposed development. No operational mitigations are recommended. Highlands View - Lake Oswego, OR 173 PROJECT DESCRIPTION INTRODUCTION The property located at 12800 Goodall Road in Lake Oswego, Oregon, has been proposed for subdi- vision. The proposed Highlands View will contain 16 lots developed with single-family dwellings. This report looks at the traffic impacts of the proposed subdivision on the transportation system in the vicinity of the site. The purpose of this report is to provide an analysis that addresses the impacts on adjacent local residential streets as well as the operation of nearby study intersections to ensure safe and efficient performance. All supporting data and calculations are included in the appendix to this report. LOCATION DESCRIPTION The subject property is located on the northeast corner of Knaus Road at Goodall Road in Lake Oswego, Oregon. The subdivision will take access from two locations: a western access to Goodall Road and a southern access to Knaus Road. To identify any traffic impacts from the land division, the following public intersections were selected for analysis: + SW Boones Ferry Road at SW 19'x' Avenue • Country Club Road at Goodall Road • SW Boones Ferry Road at Knaus Road + Knaus Road at Goodall Road SW Boones ferry Road is under the jurisdiction of the City of Lake Oswego and is classified as a Minor Arterial. It is generally a two-lane facility with a speed limit of 35 mph in the vicinity of the site. There are intermittent curbs and sidewalks installed along both sides of the street. No on -street parking areas or bike lanes are provided. Country Club Road is under the jurisdiction of the City of Lake Oswego and is classified as a Major Arterial. It is generally a five -lane facility with a posted speed limit of 30 mph. Curbs and sidewalks are installed along the north side of the street and bike lines are provided on both sides. No on -street parking areas are provided. Knaus Road is under the jurisdiction of the City of Lake Oswego and is classified as a Neighborhood Collector. It is a two-lane facility with a statutory residential speed limit of 25 mph. There are in- termittent curbs and sidewalks in place along both sides of the street and speed bumps installed be- tween Boones Ferry Road and Goodall Road. On -street parking is permitted where space is availa- ble. No bike -lanes are provided. Goodall Road is under the jurisdiction of the City of Lake Oswego and is classified as a Neighbor- hood Collector south of Adrian Court. North of Adrian Court the street becomes SW 19'11 Avenue Highlands View - Lake Oswego, OR 4 174 and is classified as a Local Street. It is a two-lane facility with a statutory residential speed limit of 25 mph. A speed bump is installed between SW Boones Ferry Road and Knaus Road for traffic calming. No curbs, sidewalks, or bike lanes are provided in the vicinity of the subject property. On - street parking is generally permitted, except where shoulders are insufficient to accommodate parked vehicles. The intersection of SW Boones Ferry Road at SW 19th Avenue is a four -legged intersection con- trolled by a STOP sign on the north and southbound 19`' Avenue approaches. Just north of the inter- section, SW 19'h Avenue forks into SW Clara Lane. Each approach at the intersection has a single shared lane for all turning movements. The intersection of Country Club Road at Goodall Road is a three-legged intersection controlled by a STOP sign on the southbound Goodall Road approach. The eastbound approach on Country CIub Road has a dedicated left -turn lane and two through lanes while the westbound approach has a through lane and a shared through/right-turn lane. The southbound approach on Goodall Road has a single shared lane for all turning movements. The intersection of SW Boones Ferry Road at Knaus Road is a three-legged intersection controlled by a STOP sign on the Knaus Road approach, The westbound approach on Knaus Road and the northbound approach on Boones Ferry each have a single shared lane for all turning movements. The southbound approach on Boones Ferry has a through lane and a dedicated left -turn lane. The intersection of Knaus Road at Goodall Road is a four -legged intersection under four-way stop control. Each approach has a single shared lane for each turning movement. A vicinity map showing the project site and the study area intersections is shown in Figure 1 on page seven.

The development plan proposes the construction of 16 single-family dwellings. To estimate the trip generation of the subject property, trip rates from land -use code 210, Single -Family Detached Hous- ing, was used based on the number of dwelling units. The trip generation calculations show that the proposed development will generate a total of 12 trips during the morning peak hour with 3 trips entering and 9 trips exiting the site. During the evening peak hour, the property is projected to generate a total of 16 trips with 10 entering and 6 exiting the site. The following table offers a summary of the trip generation. Detailed trip generation calcula- tions are included in the appendix to this report.

Boones Ferry Road provides a route to either In- terstate 5 if traveled south or to SW Terwilliger Boulevard to the north. Country Club Road provides the route into downtown Lake Oswego. The trip distribution for the Highlands View subdivision was derived using existing traffic pattern at the study intersections. Using these patterns, it was projected that majority (45%) of site traffic will arrive or depart to the southwest between Boones Ferry Road and Country Club Road in the direc- tion of Interstate 5 while slightly less (30%) will travel to and from destinations from the north along Boones Ferry. The remaining patrons (25%) will originate or terminate their trips in downtown Lake Oswego to the east.

Sight distance requirements are based on an approaching driv- er's eye height of 3.5 feet above the road and an eye height of 3.5 feet with the opposing driver's eye 15 feet behind the edge of the near -side travel lane. Sight distance was measured at the western property access with Goodall Road and found to be 309 feet to the north, limited by a crest vertical curve, and found to be in excess of 342 feet to the south beyond the STOP sign at the intersection with SW Knaus Road. Based on the posted 25 mph speed limit on SW Goodall Road, a minimum of 280 feet of intersection sight distance (ISD) is required to allow vehicles to turn onto Goodall Road without impeded the flow of through traffic. In the interest of roadway safety, speeds of southbound through traffic along Goodall Road were sampled to identify the normal travel speed to ensure safe stopping sight distance (SSD). The 85`h - percentile speed of traffic traveling southbound over the crest vertical curve was found to be 26 mph. Based on this speed, traffic would require a minimum of 183 feet of sight distance in order to stop safely. Based on the available sight distance, travel speeds of up to 36 mph would be able safely stop for traffic entering the roadway. These calculations conservatively assumes a 2.5 -second per- ception reaction time, a comfortable 11.2 ft/sect rate of deceleration, and account for the approxi- mately 9 percent downhill grade on the approach. Sight distance for the western access to Goodall Road is adequate for both ISD standards as well as SSD standards. Due to the geography next to the roadway and vegetation within the right-of-way, sight distance for the southern access with Knaus Road could only be measured at the edge of pavement. Adjustments were made in the field under the assumption that the access would be built to allow the driver a clear line of sight from 3.5 feet above the road edge when positioned 15 feet from behind the edge of the near -side travel lane. Sight distance from the proposed southern access was measured to be 377 feet to the east, limited by a crest vertical curve, and measured to be 317 feet to the west, also limited by a crest vertical curve. Based on the posted 25 mph speed limit on Knaus Road, a minimum of 280 feet is required to meet ISD standards. Speed data was also gathered at the proposed southern access. The 85th -percentile speed for east- bound and westbound traffic on Knaus Road was found to be 28 mph. Based on this speed and the 9 percent downhill grade on the westbound approach, a minimum of 204 feet of stopping sight dis- tance is required. Based on the available sight distance measured in the field, travel speeds up to 41 mph would be able to safely stop for traffic entering the roadway. Highlands View - Lake Oswego, OR 11 181 For the eastbound approach, based on a 5 percent grade, it was calculated that traffic would require 191 feet to meet SSD standards. The available sight distance in this direction allows for traffic trav- eling up to 39 mph to safely stop for vehicles entering the roadway. Since sight lines are currently inadequate due to the vegetation and geography next to the roadway. It is therefore recommended that vegetation be cleared and the driveway be constructed to allow the driver to be at the level of the roadway when positioned 15 feet back from the near -side travel lane. With these improvements, sufficient sight distance will be available in both directions to meet both the TSD and SSD standards. No other sight distance mitigations are recommended. CRASH DATA ANALYSIS Using data obtained from the Oregon Department of Transportation's Crash Data System, a review was performed for the most recent available five years of crash data (January 2008 -- December 2012) for each of the study intersections. A crash rate was calculated under the common assumption that traffic counted during the PM peak period represents 10% of the average daily traffic (ADT) at the intersection. Crash rates greater than 1.0 crash per million entering vehicles (CMEV) are gener- ally indicative of a need for further investigation and possible mitigation. The intersection of SW Boones Ferry Road at SW 19`h Avenue had a total of two reported crashes during the analysis period giving a crash rate of 0.10 CMEV. Both crashes were rear -end type colli- sions that resulted in property damage only (PDO). There were a total of four reported crashes at the intersection of Country Club Road at Goodall Road during the analysis period giving a crash rate of 0.11 CMEV. One crash involved leaving the road- way and colliding with a fixed object, one crash involved a turning vehicle, one crash involved a ve- hicle backing into the roadway, and one crash was a rear -end type collision. All four crashes only resulted in property damage. The intersection of SW Boones Ferry Road at Knaus Road had a total of four reported crashes during the analysis period giving a crash rate of 0,1 S CMEV. Three crashes were rear -ends and one crash was a side -swipe meeting collision. One crash resulted in property damage only, two crashes result- ed in possible injury or complaint of pain (Injury -C), and one crash resulted in a non -incapacitating injury (Injury -B). The intersection of Knaus Road at Goodall Road had one reported crash during the analysis period giving a crash rate of 0.21 CMEV. The crash was an angle -type collision and resulted in a non - incapacitating injury. Based on the detailed analysis, no significant safety concerns were identified and no safety mitiga- tions are recommended. Highlands View - Lake Oswego, OR 182 92 WARRANT ANALYSIS Left -turn lane warrants and traffic signal warrants were examined for each of the applicable study intersections. A left -turn lane is primarily a safety consideration for the major street, removing left -turning vehicles from the through traffic stream. The left -turn lane warrants were examined using the methodology outlined in the NCHRI' Report #457, published by the Transportation Research Board in 2001. The turn lane warrants are evaluated based on the number of advancing and opposing vehicles as well as the number of turning vehicles, the travel speed, and the number of through travel lanes. The speed used in the calculations was the posted speed limit for the major street. The analysis shows that the high volume of existing traffic meets left -turn lane warrants for a south- bound left -turn lane at the intersection of SW Boones Perry Road at SW 19'h Avenue. The proposed 16 -lot subdivision contributes a nonunal amount of traffic (Iess than 5%) to the left -turning move- ment and an even more negligible amount of traffic in total (Iess than 0.5%) at this intersection. Since the proposed development neither triggers the need for a left -turn lane nor substantially affects the need for this improvement, a condition of approval requiring construction of the left -turn refuge would not be proportional to the amount of traffic generated by the subdivision. Accordingly, no mitigation is recommended in relation to the proposed development. Due to the low volumes projected to use each of the site accesses, the low volumes along the major streets, and the low approach speeds, left -turn lane warrants are not projected to be met along Knaus or Goodall Road. Low volumes were observed for the minor street approaches at each of the study intersections. By examination, traffic signal warrants are not projected to be met under any of the analysis scenarios. Signalization of any of the study area intersections is not recommended. Highlands View - Lake Oswego, OR 13 183 OPERATIONAL ANALYSIS BACKGROUND TRAFFIC Prior to assigning the site trips to the study area intersections, existing volumes were adjusted to ac- count for the anticipated growth in the area that occurs during the construction of the development. Background traffic volumes were projected for year 2016 conditions, when the proposed develop- ment is assumed to be completed and fully occupied. To estimate the future traffic volumes, a compounded growth rate of 2.0 percent per year was used. This growth rate was applied over the three-year period to the observed year 2013 traffic volumes in order to determine the expected year 2016 background traffic volumes. These volumes are shown in Figure 4 on page 15. The background traffic with the addition of site trips from the proposed devel- opment is shown in Figure 5 on page 16.

The intersections were analyzed using the unsignalized intersection analysis methods in the HIGHWAY CAPACITY MANUAL, published by the Transportation Research Board. Level of service (LOS) can range from A, which indicates very little or no delay, to F, which indicates a high degree of congestion and delay. The City of Lake Oswego requires a level of service E or better at the study intersections, To examine the impacts of the proposed subdivision, an analysis was made for the morning and evening peak hours for existing conditions, year 2016 background traffic conditions, and year 2016 background plus site trips from the proposed development. Currently, the intersection of SW Boones Ferry Road at SW 19`h Avenue operates at level of service C during the AM peak hour and level of service B during the PM peak hour. Under 2016 traffic conditions, the operation of the intersection is projected to remain unchanged during both peak hours, regardless of the additional traffic from the proposed subdivision. The intersection of Country Club Road at Knaus Road currently operates at level of service D during the morning peak hour and level of service C during the evening peak hour. Under 2016 traffic con- ditions, the intersection is projected to operate at level of service E during the morning peak hour and level of service D during the evening peak hour, regardless of additional traffic from the proposed development. The intersection of SW Boones Ferry Road at Knaus Road is presently operating at level of service C during both peak periods. In three years, the intersection is projected to continue operating at level of service C under both analysis scenarios. The intersection of Knaus Road at Goodall Road is currently operating at level of service A during both peak periods. The operation of this intersection is projected to remain unchanged in three years regardless of the additional trips from the proposed development. Both site accesses are projected to operate at level of service A during both peak periods under 2016 traffic conditions. Based on the operational analysis, all study intersections are projected to operate acceptably under all analysis scenarios. No operation mitigations are recommended. The results of the capacity analysis, along with the levels of service, delay, and We ratios are shown in the table on the following page. Detailed calculations, as well as tables showing the relationships between delay and level of service are included in the appendix to this report.

The operational analysis of the study area show adequate capacity through year 2016 regardless of additional trips resulting from the proposed development. No operational mitigations are recom- mended. A detailed observation of the crash history at the study intersections shows no trends that are indica- tive of safety issues that need to be addressed. No safety mitigations are recommended. Sight distance was measured at the location of the western property access to Goodall Road and found to meet both the intersection sight distance standards for the posted speed limit as well as the stopping sight distance standards for the 0' -percentile speeds observed for traffic approaching the access from the north. Sight distance for the southern property access to Knaus Road was measured assuming that the vege- tation along the property frontage be cleared and that the access be constructed to allow the driver to be at the level of the roadway when positioned 15 feet back from the traveled way. With these as- sumptions, it was found that sight distance would be sufficient to meet both the intersection sight distance standards for the posted speed limit as well as stopping sight distance standards for the W' - percentile speeds observed for traffic approach from either direction. Left -turn lane warrants found to be met under existing conditions for the intersection of SW Boones Ferry Road at SW 19'b Avenue. Since the warrant is met before the addition of any site traffic, no mitigations in relation to the proposed development are recommended. Traffic signal warrants are not projected to be met for any study area intersection at any time during development. No mitiga- tions are recommended. Based on the detailed analysis, no mitigations are required or recommended for the proposed High- lands View development. Highlands View - Lake Oswego, OR 19 189 APPENDIX Highlands View - Lake Oswego, OR 190 20 LEVEL OF SERVICE Level of service is used to describe the quality of traffic flow. Levels of service A to C are considered good, and rural roads are usually designed for level of service C. Urban streets and signalized intersections are typically designed for Ievel of service D. Level of service E is considered to be the limit of acceptable delay. For unsignalized intersections, level of service E is generally considered acceptable. Here is a more complete description of levels of service: Level of service A: Very low delay at intersections, with all traffic signal cycles clearing and no vehicles waiting through more than one signal cycle. On highways, low volume and high speeds, with speeds not restricted by other vehicles. Level of service B: Operating speeds beginning to be affected by other traffic; short traffic delays at intersections. Higher average intersection delay than for level of service A resulting from more vehicles stopping. Level of service C: Operating speeds and maneuverability closely controlled by other traffic; higher delays at intersections than for level of service B due to a significant number of vehicles stopping. Not all signal cycles clear the waiting vehicles. This is the recommended design standard for rural highways. Level of service D: Tolerable operating speeds; long traffic delays occur at in- tersections. The influence of congestion is noticeable. At traffic signals many vehicles stop, and the proportion of vehicles not stopping declines. The number of signal cycle failures, for which vehicles must wait through more than one signal cycle, are noticeable. This is typically the design level for urban signalized intersections. Level of service E: Restricted speeds, very long traffic delays at traffic signals, and traffic volumes near capacity. Flow is unstable so that any interruption, no matter how minor, will cause queues to form and service to deteriorate to Level of service F. Traffic signal cycle failures are frequent occurrences. For unsignalized intersections, level of service E or better is generally considered acceptable. Level of service F: Extreme delays, resulting in long queues which may interfere with other traffic movements. There may be stoppages of long duration, and speeds may drop to zero. There may be frequent signal cycle failures. Level of service F will typically result when vehicle arrival rates are greater than capacity. It is considered unacceptable by most drivers. 191 LEVEL OF SERVICE CRITERIA FOR SIGNALIZED INTERSECTIONS FLEVEL F SERVICE CONTROL DELAY PER VEHICLE (Seconds) A <10 B 10-20 C 20-35 D 35-55 E 55-80 F >80 LEVEL OF SERVICE CRITERIA FOR UNSIGNALIZED INTERSECTIONS LEVEL OF SERVICE CONTROL DELAY PER VEHICLE (Seconds) A X10 B 10-15 C 15-25 D 25-35 E 35-50 F >50 192 Whereas, the Oregon Department of Transportation, has been requested to perform an investigation pursuant to the provisions of ORS 810.180, has caused an engineering and traffic investigation to be made for the section(s) of state highway, county highway, city highway, or highway under the jurisdiction of a federal agency described below (highway means public way); and Whereas, the State Traffic Engineer has been authorized to act on behalf of the Oregon Transportation Commission; and Whereas, the data, facts, and information obtained in connection with said engineering and traffic investigation are on file in the office of the Traffic Management Section of the Oregon Department of Transportation in Salem, Oregon; and Speed Zone Order trate October 16, 2006 1 Order No J7778 Jurisdiction(s) Clackamas Co.

T. Smith Companies THRU: 3J Consulting, inc. FROM: Walter H. Knapp SUBJECT: The Highlands - Arborist Report This arborist report for The Highlands site at 12800 Goodall Road in Lake Oswego is based on site visits on September 9 and 12, 2013 by Certified Arborists Walt Knapp (PN -0497A) and Todd Prager (WE -6723A). All trees were inventoried to determine their species, size, and condition. The report summarizes the findings from the two site visits, designates trees to be retained or removed, and includes tree protection recommendations as required by Article 55.08 of the Lake Oswego Code. General Description. The 7.35 acre Highlands site is located at the northeast corner of the intersection of Goodall and Knaus Roads in Lake Oswego. The property slopes upward from Goodall and Knaus Roads towards the north central portion of the site where there is an existing house, driveway, and sports court. The trees surrounding the house are primarily small diameter, ornamental and fruit trees. To the south of the house is an open field, with trees along the perimeter creating a buffer from Goodall Road, Knaus Road, and the residences directly east of the site. The trees along the perimeter are primarily medium to large diameter evergreens interspersed with some deciduous and invasive trees. Finally, there are large diameter cedars framing the driveway entrance at Goodall Road and one to the southwest of the existing house. Tree Inventory. A total of 102 trees measuring five inches in diameter and larger were inventoried. Seventeen species were represented, with shore pine (Pinus contorta var. contorta) on the perimeter of the property the most common. Table 1 provides a summary of the trees by species. Complete tree -by -tree data are shown in the tree inventory. Table 1.

Ornamental 5 red oak Quercus rubra Ornamental, Specimen 3 Total 102 cs? LJL rn H o M v X LLJ J Tree Preservation and Removal. A total of 55 trees are planned for retention under the current proposal, and 47 will be removed (table 2). No trees growing in the vicinity of the existing house are currently planned for removal except for invasive species. Many of the larger specimens, most notably a high-quality red oak (Quercus rubra), 5 ponderosa pines (Pinus ponderosa), and 3 cedars (Cedrus atlantica and Cedrus deodara), will be protected and retained. Reasons for tree removal include invasive species (20), location within a right-of-way (6), road construction and site grading (10), storm drains (2), home construction (3), and landscape enhancement (6). A summary of tree removal by removal category is included in Appendix A. Landscape Enhancement. The large shore pines on the cast side of the property are mature, estimated to be in excess of half a century in age. Although they are in fair to good condition presently, they have not been maintained by pruning to reduce the incidence of large lateral limbs subject to breakage in storms. Corrective pruning at this point is not feasible, due to large limb size and slow mature growth, making large branch failure more likely. Furthermore, the trees are directly exposed to the south, the direction of major storm winds, as well as on a downslope, which tends to accelerate wind velocity. Although none of these trees are considered high risk at the present time, replacement with low -growing species will reduce risk of failure, be more consistent with residential landscape design, and enhance the openness of the site. Note that in this area, the few remaining native Washington hawthorn trees will be retained, but the invasive tree species, which are inconsistent with site development objectives and enhancement of the landscape, will be removed. Tree Protection Recommendations. The following tree protection requirements as listed in Articles 55.08.030 and 55.08.040 of the Lake Oswego Code will apply to all trees planned for retention: 1. Except as otherwise determined by the City Manager, all required tree protection measures set forth in this section shall be instituted prior to any development activities, including, but not limited to clearing, grading, excavation or demolition work, and shall be removed only after completion of all construction activity, including landscaping and irrigation installation. 2. Chain link fencing, a minimum of 6 feet tall with steel posts placed no farther than ten feet apart, shall be installed at the edge of the tree protection zone or dripline, whichever is greater, and at the boundary of any open space tracts or conservation easements that abut the parcel being developed. 3. The fencing shall be flush with the initial undisturbed grade. 4. Approved signs shall be attached to the chain link fencing stating that inside the fencing is a tree protection zone, not to be disturbed unless prior approval has been obtained from the City Manager and arborist for the project. 5. No construction activity shall occur within the tree protection zone, including, but not limited to dumping or storage of materials such as building supplies, soil, waste items, or parked vehicles or equipment. 6. The tree protection zone shall remain free of chemically injurious materials and liquids such as paints, thinners, cleaning solutions, petroleum products, and concrete or dry wall excess, construction debris, or run-off. 7615 SW Dunsmuir Lune, Beaverton, OR 9 700 7 Phone. (503) 646-4349 Fax: (503) 747-4863 260 7. No excavation, trenching, grading, root pruning or other activity shall occur within the tree protection zone unless directed by an arborist present on site and approved by the City Manager. 8. Inspection. The applicant shall not proceed with any construction activity, except installation of erosion control measures, until the City has inspected and approved the installation of the required tree protection measures and a building and/or grading permit has been issued by the City. Summary. The Highlands development in Lake Oswego will retain and protect 55 of the 102 inventoried trees on the site, and 47 will be removed. Most of the trees being retained surround the existing house; however, on the broader site, many of the larger, high quality specimens will be retained. Protection requirements will adhere to Articles 55,08.030 and 55.08.040 of the Lake Oswego Code. • Walter H.

F. In order to provide certainty for the Developer and FHNA regarding the proposed development, and to ensure the construction and orderly provision of adequate public facilities to the development, Developer and City desire to enter into this Agreement. AGREEMENT In consideration of the mutual promises and performance obligations of each Party set out in this Agreement, the City and Developer hereby agree to the following terms and conditions, including the five (5) exhibits, attached hereto and incorporated as referenced herein.

Description of Development Authorized and Required by this Development Agreement. 2.1 Permitted Use. The permitted uses are single -'family residential use and accessory uses associated with single-family residential use. 2.2 Density. The ultimate maximum density will be 16 single-family residential dwelling units, each on a separate parcel, developed in a series of three partitions over three years. The first of these partitions occurred in 2013, and the two remaining partitions are scheduled to be applied for and recorded in 2014 and 2015, respectively. Development will be consistent with the preliminary plan attached as Exhibit B ("Preliminary Plan"). 2.3 height and Size of Structures.

The Developer will prepare and record architectural covenants that govern the exterior design of structures within the development. These covenants are neither required by the City as part of this Development Agreement nor will be enforceable by the City, but nevertheless the Developer represents to the City, for the benefit of FHNA, that the Developer will require use of high-quality architectural features and materials for all permanent structures and will require that all walls of residences facing public streets incorporate windows. The covenants relating to exterior design of structures must comply with all applicable city code requirements, e.g. LOC 50.06.001.2. These covenants will run with the land and bind future builders and owners. Any modification of the covenants shall not eliminate the necessity for compliance with all applicable city code requirements. 2.5 Landscape Buffers. Developer will design and install a landscape buffer on the boundaries of the Property, as illustrated in Exhibit C, adjacent to Knaus Road and Goodall Road in order to buffer the view of the Property from adjacent streets and homes. Pursuant to LOC 50.06.004.2.c.i, a "bad neighbor" fencing will not be installed on the boundaries. 2.6 Exterior Illumination on Residences. Although not required by the City as part of this Development Agreement nor enforceable by the City, nevertheless the Developer represents for the benefit of FHNA that exterior ill«mination on residences shall be designed and operated consistent with "dark sky" principles concerning shielding, orientation, and type of lamp. 3. infrastructure Improvements and Dedications. The Developer will be responsible, at Developer's expense, for constructing all of the required public infrastructure and services as set forth in the Master Plan ibr the development, further described in Section 5, below. Developer: 3.1 Shall complete all such public improvements prior to the recording of the final plat for the second partition; or 3.2 May record the final plat prior to completion of the required public improvements pursuant to LOC 50.07.003.9, provided that the Developer posts a bond, letter of credit or other security acceptable to the City sufficient to fulfill the obligation to construct the public improvements prior to the issuance of any building permits for any residences on the site, as set forth in the Master Plan. The amount of the bond shall be 120% of the estimated cost of constructing the public improvements as determined by Developer's engineer, subject to review and approval by the City engineer. Except as otherwise provided in this Agreement, Developer will dedicate the public rights-of-way and easements as required by the Master Plan on the final plat for the first partition. City acknowledges that, subject to Developer's provision of public infrastructure and services in accordance with this Section 3, Developer will have met the requirement of LOC 50.07.003.5 to alleviate the need for public services and sidewalks created or 3 37891 44711.1iGA1.27537M).12 271 contributed to by the proposed development for the Knaus Road and Goodall Road rights-of-way. Additional off-site public improvements, if any, will be addressed in the Master Plan as referenced in Section 3.6. 3.3 Streets within the development shall be developed consistent with the City Engineer's Policy Memorandum entitled "Guidelines and Standards for New Streets and Frontage Improvements in the Urbanizing Rural Fringe and Transition Neighborhoods" (effective February 1, 2005). 3.3.1 Pathways shall be designed to match pathways existing on the effective date of this Agreement on the south side of Knaus Road in the vicinity of the Property. 3.3.2 New street lights shall be: (a) located only at street intersections pursuant to LOC 50.06,004.3.b.v; (b) limited to a total of three (3) within the development; (c) Providence style lamp on visco pole using LED lights, and (d) designed and operated consistent with LOC 50.06.004.3.b.v.

LOC 50.06.005.1.a requires Major Partitions (defined as a partition that includes the creation of a street) with more than 75,000 square feet of area provide twenty percent (20%) open space. Because Developer has applied for and recorded one partition plat and will apply for approval of two more Major Partitions as described in Section 2.3 above, the twenty percent (24%) landscaping requirement shall be calculated on the entire 7.35 acre development site; each of the three Major Partitions that are the subject of this Agreement may have more or less than twenty percent (20%) open space, PROVIDED the total open space provided in the three (3) Major Partitions equals at least twenty percent (20%) of the gross acreage of the entire 7.35 -acre development site. A copy of the open space plan for the Property demonstrating compliance with this requirement is set forth in Exhibit C. 3.5 Creation of Public Right -of -Way by Separate Instrument. Developer proposes to dedicate, and the City agrees to accept, a deed attached as Exhibit D providing for the dedication in favor of the public that certain real property described in Exhibit D for the purpose of a public street, prior to the recording of a Major Partition Plat. The dedication of the property legally described in Exhibit D conforms to the location of the public street shown in the Preliminary Plan depicted in Exhibit B to be achieved through a Type I property line adjustment. Even though the street is being dedicated prior to the Master Plan approval for partitions that will use the street for access, rather than as a condition of approval of the creation of the Master Plan, the partitions shall still be considered to be "major" partitions for purposes of compliance with applicable code provisions. 3.6 Master Plan. The Developer shall submit a Master Plan application for approval by the City. 37891-[N1A71LEGAL27537845.12 272 4 4. Fees and Charges. The fee charged for the review of the Master Plan shall equal the City's fee for the review of subdivision, as of the date of the application for the Master Plan.

Schedule and Procedure for Compliance Review. 5.1 Within 60 days after approval of this Agreement, Developer shall submit a Master Pian for the serial partitions to the City for approval. The Master Pian shall be consistent with the Preliminary Plan and shall consist of 5.1.1 Pians showing the approved partition for 2013 and the proposed partitions for calendar years 2014 and 2015. 5.1.2 A final plan showing development at build out, including required public infrastructure. 5.1.3 A development schedule, including a schedule for review of building, grading and other permits. 5.2 City shall review the proposed Master Plan as a "minor development" as that term is utilized in the LOC.

Developer acknowledges that the FI INA's unequivocal support of the Agreement will not prevent meaningful participation by the FHNA during the Master Plan process, 5.3 Notwithstanding Section 3.5 of this Agreement, following approval of the Master Plan, subsequent partitions shall be reviewed as ministerial developments pursuant to the LOC. The sole criterion for approval of subsequent partitions is demonstration of compliance with the approved Master Plan. 5.4 following approval of the Master flan, the City shall review any proposed amendments to the Master Plan as a minor development pursuant to the LOC.

Developer shall execute and record a notice of occupancy prohibition until the parcel upon which the residence is located is created in a recorded partition plat so that there is only one occupied house upon each parcel; a termination of such notice shall be recorded with the approval of the City prior to issuance of an occupancy permit. Developer shall not apply for early building permits until the Property contains nine (9) lots of record, as reflected in the phasing plan in Exhibit L. In consideration for the allowance of early construction and to assure that each dwelling is on a lot of record by January 1, 2016, Developer shall file a complete and executed partition application or applications into an escrow account with instructions that the application or applications may be submitted and processed for approval and recorded by the City ifa final partition plat is not recorded by January 1, 2016 that results in a dwelling not being on its own lot of record. Developer shall, prior to issuance of an early building permit for a second house on a parcel, submit an irrevocable letter of credit in favor of the City for the costs of processing and recording the partition, in such amount as determined by the City Manager. 7. Continuing Effect of Agreement. 7.1 In the ease of any change in regional policy or federal or state law or other change in circumstance which renders compliance with this Agreement impossible or unlawful, the Parties will attempt to give effect to the remainder of this Agreement, but only if such effect does not prejudice the substantial rights of either Party under this Agreement. If the substantial rights of either Party are prejudiced by giving effect to the remainder of this Agreement, then the Parties shall negotiate in good faith to revise this Agreement to give effect to its original intent. If, because of change in policy, law or circumstance, this Agreement fails of its essential purpose (vesting of allowed uses and limitations on development conditions and fees and charges) then the Parties shall be placed into their original position to the extent practical. It is the intent of this Agreement to vest development rights and conditions, including but not limited to the permitted uses, density and intensity of uses, infrastructure improvements and fees and charges as set forth in this Agreement, notwithstanding any change in local ordinance or policy. 7.2 The Property is within the City limits of the City of Lake Oswego, so the requirements of ORS 94.504(2)(L) are not applicable to this Agreement. 8.
