No action is required at this time. Tonight's presentation is to provide background and a framework for the
Emergency Operations Plan (EOP) that will be presented to the Council for adoption at your December 14,
2010 Council Meeting. The plan is currently in draft form and going through final staff review. Copies of
the plan will be distributed to the Council in mid November.
INTRODUCTION/BACKGROUND
The City of Lake Oswego is currently operating with an Emergency Operations Plan (EOP) that was originally
adopted in 1994 with parts of the plan updated in 1998. A Council goal for 2010 is to update and adopt this
Plan and make sure it is responsive to emergency conditions in Lake Oswego and is completed in the most
organized, efficient and effective manner possible.
As is the case for all local governments, the Lake Oswego EOP needs to be NIMS (National Incident
Management System) compliant and based on the National Response Framework. To accomplish this, the
State of Oregon Office of Emergency Management has contracted with a private company (Ecology and
Environment) to assist all counties and cities in Oregon in the updating of their EOP's. The goal is to create
plans throughout the state that are consistent, sharing the same format and terminology. Ecology and
Environment (E&E) is in the process of completing the EOP for Clackamas County. Lake Oswego was
aggressive in making sure we were the first City in the County to start the EOP update process after E&E
finished with Marion County this past summer. The timing of our desire to update the plan has worked out
well and we have benefited from the State coordinating and paying for a vender to assist local
governments. We met with Ecology and Environment for the first time on October 13, 2010 to kick off the
project and we recently completed our first review of a draft of the plan. We fully expect the plan will be
completed by early December and will be ready for your consideration in December.

Lake Oswego's Emergency Management Program
Historically, the City's emergency management function has been provided by the Lake Oswego Fire
Department under the leadership of our Assistant Chief Larry Goff. Starting with fiscal year 2009-2010, the
decision was made to place Emergency Management in the City Manager's Office to give it greater visibility
and broaden the nature of its role in the organization rather than having it so closely connected to the Fire
Department. A position (management analyst) was budgeted in the City Manager's office and an
individual was hired with the goal of spending about half their time on emergency management
responsibilities, with the remainder focused on risk management and other analytical work. The individual
hired is no longer with the City and the decision was made to not fill the position and redistribute
emergency management and risk management responsibilities to existing staff. As Assistant City Manager,
I assumed responsibility for emergency management and assembled a team with Assistant Chief Larry Goff
and Citizens Information Specialist Bonnie Hirshberger. Both have extensive emergency management
experience and have been extremely valuable in reviewing and giving input to the EOP. Human Resource
Director Megan Phelan has taken on the Risk Management function and has done an outstanding job of
identifying deficiencies, and rebid our broker relationship resulting in better advice and assistance while at
the same time lowering our costs.
The Emergency Operations Plan that is currently being finalized is an all hazard plan describing how the City
will organize and respond to incidents. It establishes guidance for the City of Lake Oswego's actions during
response to, and short term recovery from, major emergencies and disasters. The EOP describes the roles
and responsibilities of City departments and personnel when an incident occurs, and it establishes a
strategy and operating guidelines that support NIMS and the principles of the Incident Command System
(ICS). As part of the EOP, NIMS must be adopted by the City Council and it was by resolution in July 2005.
The EOP consists of what is called the Basic Plan that goes through each of these roles and is supported by
15 separate Emergency Support Functions or ESF's which are very specific in their focus. Examples of ESF's
include Communication, Transportation, Search and Rescue. Finally the plan will contain an updated
version of the Emergency Code to be adopted by the City Council as part of the plan.
Also relating to Emergency Management is the Natural Hazards Mitigation Plan Addendum adopted by City
Council in March 2010. That plan was developed in cooperation with Clackamas County Emergency
Management to comply with FEMA requirements. The plan was an update to a 2004 plan and enabled us
to apply for a FEMA grant for flood mitigation resulting in a grant for over $900,000 which is currently being
used on a project to increase the spillway and release of water at Oswego Lake dam. The Natural Hazards
Mitigation Plan is a very comprehensive resource and can be found on the City Manager's Office page of
our website http://www.ci.oswego.or.us/citymgr/Emergency/Documents/LONHMPAPri12010.pdf. One
other key piece of additional information to remember is that Goal Seven of the Comprehensive Plan
(Areas Subject to National Disasters & Hazards) is also being updated and the City Manager's Office is
coordinating with the Planning Department on their efforts.

DISCUSSION
On Tuesday, November 9th you will hear a 20-30 minute presentation that will not only cover an update on
the EOP update, but also give you an overview of several other key elements of emergency management.
This includes a discussion of the CERT (Citizens Emergency Response Team) program, an outstanding
community based approach to emergency response taught by our Fire Department. Bonnie Hirshberger
completed this program last year and I just completed the eight-week program last week. You will also
hear about the City's approach to emergency management training. Although, the EOP completion is
important, our team ultimately believes the most valuable thing we can do is to utilize the plan in a training
exercise and get people familiar with their roles. This is especially important for Lake Oswego as we have
several new managers in key positions.
Other subjects we will briefly discuss in our November 9 presentation include reviewing our website and
what it offers, and reminding people of the opportunity to attend the November 10 Emergency
Preparedness Forum (6pm to Bpm at City Hall) which can be found at
http://www.ci.oswego.or.us/citvmgr/Emergency/Documents/PreparednessAgendaandbios111010.pdf
In addition, we will talk about our plan to incorporate the role of the Mayor and Council in emergencies at
the orientation for new and remaining councilors in January 2011.
As always, please contact me if you have any specific questions or concerns related to the EOP or
emergency management in general.
RECOMMENDATION
This report is for informational purposes and requires no action at this time. The Council will be asked to
review and adopt a recommended Emergency Plan at your December 14, 2010 meeting.

FROM: Jonna Papaefthimiou, AICP
Planning and Building Services Department
SUBJECT: Proposed Changes to LOC 50.16 "Sensitive Lands"
DATE: October 27, 2010
ACTION
CITY OF LAKE OSWEGO

PO Box 369
Lake Oswego, OR 97034

This report is for information only; no action is requested at this time. A public hearing on this topic is
tentatively scheduled for December 13, 2010.
INTRODUCTION/BACKGROUND
In fall 2009, the Planning and Building Services Director assembled a task force of citizen -experts to review
the City's Sensitive Lands program and suggest changes that would:
• Maintain the City's environmental quality;
• Maintain compliance with Metro and State requirements;
• Increase flexibility for property owners;
• Simplify or clarify application and review processes;
• Result in a code that could engender stronger community support.
The Second Look Task Force presented its recommendations to Council in June 2010. Council met with the
Task Force over two evenings to review the report, then held three additional public input sessions to
solicit feedback on the issues. On July 20, Council adopted Resolution 10-51A "A Resolution of the City of
Lake Oswego City Council Directing Staff to Implement Revisions to the City's Natural Resource Protection
Program" (Exhibit F-1).
Acting on the Council's direction, the Planning Commission held a work session on September 13 and a
public hearing on September 27, 2010, to discuss changes to the development code that would implement
portions of Resolution 10-51A, Section A. These changes are intended to:
• Allow developments with de minimis impacts in resources areas, such as additions to existing
homes and accessory structures.
Page 2
• Clarify the terms "ditch," "resource buffer," and "construction setback"
(The two other items in Section A, "exempt invasive trees" and "amend the City's fee schedule," do not
require Planning Commission review. Fee schedule amendments will come before Council on November
30, and changes to the tree code will be discussed in a separate report tonight.)
All sensitive lands owners and owners of possible future sensitive lands were notified of Planning
Commission meetings, and thirteen people testified at the hearing. The result of the Planning Commission
deliberations is the code text provided as Exhibit A-1.1. Planning Commission recommendations are
narrated in the discussion section below. The Public Works Department supports an additional exception
for new utilities, also noted below (5 "utility line exemption").
DISCUSSION
Allow De Minimis Impacts
LOC 50.16.015 "Applicability" lists the types of development that require review under the Sensitive Lands
chapter. Currently, the section requires review of all development except for: development in the
footprint of an existing development (vertical expansion/replacement); restoration required as a result of a
code violation; and development on a lot created before August 21, 1997, where measures to protect the
resource was adopted as a part of the original approval. Five new exceptions are proposed to allow more
flexibility:
1. Routine maintenance and repair of existing development, including non -conforming structures
and landscaping. This is already allowed, but the permission is often overlooked, so it is proposed
to be restated.
2. Alteration, expansion, or replacement of an existing primary dwelling unit where the footprint of
the new intrusion is not more than 700 square feet in the RP or RC district and no closer to a
protected water feature than the pre-existing structure. This is intended to allow a homeowner
whose house is already in a resource area to make significant additions to an existing structure,
hopefully allowing them to retain their home rather than moving or demolishing the structure. The
idea stems from Metro's Title 13 model code, which allows up to 500 SF of addition on existing
structures. The Planning Commission proposed increasing the limit to 700 SF to create even greater
flexibility.
Additions on existing structures are considered de minimis because when an existing home is
already located in a resource area, an addition to that building has a relatively small additional
impact. The Planning Commission did not choose to allow additions on structures other than the
primary dwelling unit because that would, in effect, allow existing de minimis structures to become
significant (e.g. turning a garden shed into a dwelling unit).
3. Development that meets all of the following criteria:
L Is not located within a wetland or below the top of bank of a stream,
ii. Does not require a grading permit,
iii. For lighting, is low -voltage landscape lighting.
iv. The cumulative total of all development under this subsection shall not exceed 200 square
feet.
Page 3
This exemption is intended to allow homeowners the opportunity to develop some common
backyard amenities—gardens, sheds, paved activity areas—even if they intrude somewhat into a
natural resource area.
The idea of allowing a small area of development in a protected area is borrowed from the Metro
Title 13 model code. Metro allows up to 120 square feet of new development, but does not set a
cumulative limit; Metro staff indicated that with a cumulative limit, 200 square feet of development
would be acceptable. Two hundred square feet was selected because it is also the cut-off for a
building permit. (Structures less than 200 square feet do not require building permits unless they
have electricity or plumbing.)
The proposed limitations "not within a wetland or below the top of bank of a stream," and "does
not require a grading permit," are proposed to prevent filling or piping of the water resource itself,
or filling in the floodway. The requirement for low -voltage lighting is proposed because of the
negative impact bright lights have on wildlife. Low -voltage landscape lighting is defined in the
lighting code; it is enough to light pathways, house numbers, driveway edges, etc., but dissipates at
about 8 feet. (Brighter lights, such as streetlights, would still be allowed when connected to
another permitted development.)
4. Fences located within a Wetland or below the top of bank of a stream, when the fence is
constructed so that for each 100 feet or portion thereof of fencing, at least one 2 -foot section is:
i. Not less than 12 inches above the surface, and
ii. Not more than 4 feet tall from the surface.
"Surface" shall mean the ground or water surface.
This exemption is intended to allow fences within water resource areas, as long as the fence has an
escape path so that wildlife cannot become trapped. (Fences would already be allowed in riparian
buffers and tree groves under exception (3) above.)
5. Utility Line Exemption - Repair and replacement of existing utility lines and utility line
appurtenances if they are located in an existing utility easement or in improved public right-of-
way, or new service lines where:
L The disturbed portion of the resource district is restored; and
ii. Non-native vegetation is removed from the disturbed portion of the resource area and is
replaced with native vegetation from the Lake Oswego Plants List in accordance with LOC
50.16.110.
Utility lines must connect to existing infrastructure, be located in public easements, and respect
topographic and geologic constraints. Paved rights-of-way are always the preferred location for
utilities, but given other considerations, it is sometimes impossible to avoid placing utilities in
resource areas. Therefore, when utilities are repaired or replaced in resource areas, they always
meet the test of 50.16.060 (3)(g) / 50.16.07(2)(a)(iii) "no other practicable alternative" This
proposed exemption recognizes this situation, and is intended to reduce the regulatory burden of
utility work. It would still require that construction standards be met and impacted areas be
restored when work is completed.
The Planning Commission recommended exempting only utility repair and replacement and
construction of new service lines (connection from a main to an individual structure). They did not
Page 4
recommend exempting construction of new utility lines. Planning Commission findings that support
this decision are included here as Exhibit B-1. The Public Works Department proposed and would
prefer that new utilities also be exempted from review. Their concerns and proposed alternative
language is presented in Exhibit F-2.
Clarify Terms
Three terms were identified for clarification in the Council resolution: "ditch," "resource buffer," and
"construction setback."
1. Ditch. This Department of State Lands (DSL) definition of "ditch" is widely used: "a manmade water
conveyance channel. Channels that are manipulated streams are not ditches." The Task Force and the
Planning Commission recommended that the City incorporate this definition in its code.
The DSL also publishes two definitions of ditches not subject to regulation:
Non -Jurisdictional Irrigation Ditches. Existing irrigation ditches that meet the following tests are not
jurisdictional:
(a) Are operated and maintained for the primary purpose of conveying water for irrigation; and
(b) Are dewatered during the non -irrigation season except for water incidentally retained in isolated
low areas of the ditch or are used for stock water runs, provision of water for fire suppression, or to
collect storm water runoff.
Non -Jurisdictional Roadside and Railroad Ditches. Roadside and railroad ditches that meet the
following tests are not jurisdictional:
(a) Ten feet wide or less at the ordinary high water line;
(b) Artificially created from upland or from wetlands;
(c) Not adjacent and connected or contiguous with other wetlands; and
(d) Do not contain food or game fish.
For simplicity, it is recommended that these definitions be incorporated into the City code by reference.
If the DSL further refines or adds to these definitions, then the changes will automatically be captured.
If the City uses definitions identical to DSL, the City can also ask that agency to advise if it is uncertain
whether a ditch is jurisdictional or not.
It is also recommended to add one sentence to the code section referring to resource designations (LOC
50.16.020), stating, "Ditches and Non -Jurisdictional Roadside and Railway Ditches, as defined by the
Oregon Department of State Lands, shall not be placed within the RP District."
2. Resource Buffer. The Sensitive Lands overlay protects a stream or wetland plus 25-30 feet around the
water feature to provide for functions such as flood storage and wildlife travel. The code refers to the
water feature as the "RP District", and the area around it as the "RP district buffer" or "associated
buffer." These terms create a distinction without a difference; the district and the buffer have similar
functions and are treated in the same way. The code also frequently employs the phrase "the District
and its buffer," but some references to the "RP district" also seem intended to apply to the buffer. The
Task Force proposed that this language be clarified.
Page 5
The recommendation is to eliminate the "RP resource and associated buffer" terminology altogether
and replace it with the terms "stream" or "wetland" and "protected riparian area." The water feature
and its protected riparian area together form the "RP District." This change is intended to create
consistency in the code language and accord with the intent of the code, which is to protect both the
natural feature and its riparian area for their functions and values.
3. Construction Setback. The code provides a "construction setback" to prevent resource damage during
construction. This phrase is proposed to be retained; it makes more sense with the term "protected
riparian area" (rather than the redundant -sounding "setback from the buffer").
A diagram illustrates the new and old terms applied:

To reinforce these changes, staff proposes adding the following language to the definitions section of LOC
Chapter 50:
Protected Riparian Area: the area adjacent a water resource described in LOC 50.16.070 (2). The
Protected Riparian Area may provide resource functions and values and / or protect the functions and
values of the adjacent stream or wetland.
RECOMMENDATION
This report is for information only. Staff invites Council feedback, particularly to identify additional
information that would support future deliberations. Staff also seeks Council direction regarding
exemption of new utilities from sensitive lands review.

PROPOSED CHANGES TO LOC 50.16 "SENSITIVE LANDS"
Boxed text is provided to explain proposed changes and present options for discussion. It is not
intended to be included in the adopted ordinance.
Text that is proposed to be deleted is marked withGMsSeUi.
Proposed new text is underlined.
Section 50.16.005 Overview.
1. Purpose. LOC Article 50.16 creates the Resource Protection (RP) and Resource
Conservation (RC) District overlay districts to:
(a) protect wildlife habitat;
(b) protect and improve water quality;
(c) control and prevent water pollution for the protection of public health and safety;
(d) comply with federal laws including the Clean Water Act and the Endangered
Species Act;
(e) comply with State Land Use Goal 5; and
(f) comply with Metro's Urban Growth Management Functional Plan.
2. Comprehensive Plan and Zoning Map: The overlay districts and thei • asseeiated bu
shall be designated on the Comprehensive Plan Map and Zoning Map. The purpose of these
maps is to give a general overview as to the location of the districts and the "..s,,eiated buffers
and is not intended to show the precise location of the district boundaries.
3. Sensitive Land Atlas: The boundaries of the districts and their- arse iatea b shall
be shown on individual property maps at a scale of 1:300 in the Sensitive Lands (SL) Atlas. The
SL Atlas is intended to govern the applicability of LOC Article 50.16 pursuant to LOC
50.16.015. The SL Atlas shall be adopted as part of the City's Comprehensive Plan and Zoning
This proposal would define the "resource overlay district" to include both the resource and its
associated buffer. This change is intended to simplify the code and eliminate confusion between the
resource and the buffer (which have almost identical regulations) and the construction setback (which is
treated differently). If this change is adopted, all references to "overlay districts and their associated
buffers" can be changed to simply "overlay districts."

This exception allows additions to existing homes. It is similar to what Metro allows under the Title 13
mode code; although Metro allows the exemption for all structures, Metro staff indicated that their
intent was to allow additions to a primary structure. The logic was that if an existing primary use is
already located in a resource area, an addition to that already -significant structure has a relatively small
additional impact. However, an addition to a very small structure that previously had minimal impact
would move that structure from being "de minimis" to a something significant—not what was
intended, since this section was meant to allow "de minimis" impacts only.
Staff proposed the language above to enact Metro's intent, that is, to allow additions that create
flexibility for homeowners, but avoid situations where a small structure is replaced with a more intense
use, such as turning a garden shed into a large garage or SDU.

viv. The cumulative total of all development under this subsection shall not exceed 200

This new exception would allow up to 200 square feet of new development (landscaping or structures)
in Sensitive Lands Areas. This is similar to what Metro allows under the Title 13 mode code; although
Metro allows 120 SF, it does not set a cumulative limit. Staff proposes a larger area, but with a
cumulative limit to development to prevent an entire resource from being degraded over time.
d. Fences located within a Wetland or below the top of bank o.f a stream, when the fence is
constructed so that for each 100 feet or portion thereof of fencing at least one 2 -foot section is:
i. Not less than 12 inches above the surface, and
ii. Not more than 4 feet tall from the surface.
"Surface" shall mean the ground or water surface.
The proposed new standard is less restrictive than the old standard because it allows fences within
wetlands and streams, does not require a permit to construct the fence, and only requires a 2' length of
fence for the portions of the fence within the Wetland or below top of bank to be wildlife friendly (have
an escape).

e. Utilitv Line Exemption - Repair and replacement of existing utilityles
and utility line appurtenances if they are
located in an existing, utility easement or in improved public right-of-ways or new service lines
where:
i. The disturbed portion of the resource district is restored; and
ii_ Non-native vegetation is removed from the disturbed portion of the resource area
and is replaced with native vegetation from the Lake Oswego Plants List in accordance with
LOC 50.16.110.
This new exception would simplify permitting for utility work in developed utility corridors. Itis
proposed because existing utility lines are rarely relocated; they always meet the test of 50.16.060
(3)(g) / 50.16.07(2)(a)(iii) "no other practicable alternative." This change would reduce the regulatory
burden for utility work, while still requiring that construction standards be met and impacted areas be
restored.

This exception was already included, it has just been moved. References to restoration with approved
plants were removed because they duplicate standards elsewhere in the code.
This would apply mostly to demolitions and to changes from one non -conforming landscape type to
another (e.g. lawn to flower beds).
4. wetlands, stream corridors, and tree groves that are not contained within a RP or RC
District shall not be subject to the regulations of this Article. However, an application for
development that impacts a stream corridor or wetland may still be subject to state or federal
wetland or stream regulations. Notice of such applications will be sent to the Division of State
Lands (DSL) or the Army Corp. of Engineers.
5. In addition to the notification required for the particular development by LOC
Articles 50.80 - 50.82, the City shall notify the Oregon Division of State Lands and the Army
Corp. of Engineers upon receipt of a complete application for development, change or
intensification of use within an RP District that impacts a wetland or stream corridor.
6. Mitigation Required for Violation. If development occurs in violation of this Article,
the violator shall not only be subject to any and all enforcement and penalties that can be brought
or imposed for violation of this Code he or she shall be responsible for mitigating any damage
caused by the violation to a protected resource pursuant to LOC 50.16.100 to 50.16.110.

In order to utilize the rights granted by this subsection the reconstruction must be commenced
within one year of the date of the damage and completed within two years of such date.
Section 50.16.020 Criteria for Designating Property within an Overlay District.
Applicability of RP Overlay District: The Resource Protection (RP) Overlay District shall
protect environmentally significant stream corridors and wetlands. Non -Jurisdictional Irrigation
Ditches and Non -Jurisdictional Roadside and Railway Ditches, as defined by the Oregon
Department of State Lands. shall not be placed within the RP District.
The Department of State Lands (DSL) defines non -jurisdictional ditches in the Oregon Administrative
Rules (OAR) 141-085-0515 as:
Non -Jurisdictional Irrigation Ditches. Existing irrigation ditches that meet the following tests
are not jurisdictional:
(a) Are operated and maintained for the primary purpose of conveying water for irrigation;
and
(b) Are dewatered during the non -irrigation season except for water incidentally retained in
isolated low areas of the ditch or are used for stock water runs, provision of water for fire
suppression, or to collect storm water runoff.
Non -Jurisdictional Roadside and Railroad Ditches. Roadside and railroad ditches that meet the
following tests are not jurisdictional:
(a) Ten feet wide or less at the ordinary high water line;
(b) Artificially created from upland or from wetlands;
(c) Not adjacent and connected or contiguous with other wetlands; and
(d) Do not contain food or game fish.
Referencing the OAR means the City can ask DSL for assistance if it is unable to determine whether a
channel is jurisdictional. Formatting the code in this fashion also emphasizes the City's conformity
with State rules, and keeps our code shorter. In the future, the City's code should hyperlink to the
DSL definition.
The following resources may be placed within the RP District:
a. Stream corridors and wetlands that have a HAS ranking of 50 or more (defined as
"Class I" stream corridors and wetlands).
b. Stream corridors and wetlands that have a HAS ranking of 35-49 or have a "high"
ranking for scenic values (defined as "Class II" stream corridors and wetlands).
c. Wetlands that are significant under OFWAM guidelines, including:
City of Lake Oswego Proposed Code Changes 5/26
Development Code Chapter 50.16 "Sensitive Lands"
09/27/10
i. Wetlands fed by surface flows, sheet flows or precipitation, that have evidence of
flooding during the growing season, and have 60 percent or greater vegetated cover, and are over
one-half acre in size; or other wetlands that qualify as having "intact water quality function"
under the Oregon Freshwater Wetland Assessment Methodology; or
ii. Wetlands in the Flood Management Area, that have evidence of flooding during the
growing season, and are five acres or more in size, and have a restricted outlet or no outlet; or
other wetlands that qualify as having "intact hydrologic control function" under the Oregon
Freshwater Wetland Assessment Methodology; or
iii. Wetlands where at least a portion of the resource is within a horizontal distance of
less than one-fourth mile from a water body which meets the Department of Environmental
Quality definition of "water quality limited water body" in OAR Chapter 340, Division 41.
d. All perennial streams.
Section 50.16.025 Removing an Overlay District Designation.
1. In order to remove an overlay District designation the review body shall find that one
of the following criteria areis met:
Grammatical error corrected.
a. As a result of natural occurrences or evolution the resource has been degraded
to the extent that the subject property no longer meets the criteria for designation found in
Section 50.16.020 (4) or (5) and a re-application of the ESEE analysis demonstrates that the
designation is no longer justified; or
b. There was a mistake in the analysis of quality or quantity in the original
designation of the resource and a re-application of the ESEE analysis demonstrates that the
designation no longer meets the criteria; or
c. There was a mistake in the location of the original designation of the resource
such that no portion of the resource ^ ;=was on the subject property.
All references to overlay districts and their associated buffers changed to overlay districts.
2. An overlay district designation shall not be removed as a result of damage caused by
the property owner, another party, or other than natural causes.
3. A removal application pursuant to subsection (1)(a) or (1)(b) above shall be
processed in the same manners as a designation application pursuant to LOC 50.16.020.
4. An Overlay District Designation may be removed pursuant to subsection (1)(c)
above by a delineation on the subject site in accordance with LOC 50.16.035 and a finding that
there is not now nor was there any resource located upon the site at the time of designation.
Section 50.16.030 Environmental Review.
An applicant for a development subject to this Article pursuant to LOC 50.16.015 shall comply

Section 50.16.035 Delineation of ResoaFee Streams, Wetlands, and Tree Groves.
1. Preparation/Criteria. Except as provided in subsection (4) of this section, an
applicant for a development subject to environmental review shall first delineate therem
stream, wetland or tree grove. A delineation is a more precise, site specific determination of the
location of the reseufee tree grove or water resource prepared by a qualified professional. The
delineation shall include a map showing the delineated boundary to plus or minus 2 feet. The
delineation map shall also show the bu protected riparian area, if required for the
particular resource. Resource boundaries shall be delineated as follows:
For clarity and consistency, the now text refers to "wetland, stream, or tree grove" instead of
"resource." The protected area around a stream or wetland is its "protected riparian area." The "RP
District" refers to the wetland or stream and its protected riparian area together.
A proposed change to the definition section would define "Protected riparian area."
a. Tree Groves. The RC District shall be delineated as follows:
i. The boundary of a tree grove shall be measured at the outer edge of a
contiguous tree canopy based on aerial photos and/or visual field observations, but shall not
include any tree canopy that is within an vn n:s+r-iet (St,.o.,.,., eeFfideF er- a wetland or below the

The code no longer needs to state that the RP District Buffer is not within the RP district; they will be the
same thing.
b. Wetlands. A wetland boundary shall be delineated in accordance with the
1987 Federal Manual for Identifying and Delineating Jurisdictional Wetlands, except that:
i. The methodology must include soils testing, and
ii. When a delineated wetland boundary is abutting a steep slope, the
buffer protected riparian area -shall be applied from the top of the slope rather than from the
City of Lake Oswego Proposed Code Changes 7/26
Development Code Chapter 50.16 "Sensitive Lands"

delineated boundary. The top of slope shall be determined according to the same criteria as the
top of bank, pursuant to LOC Appendix 50.16.035 (1)(c).
Buffer is replaced with "protected riparian area."
c. Stream Corridors. A stream corridor boundary shall be measured or
delineated based on topographic maps, hydrology maps, and/or field observations, pursuant to
LOC Appendix 50.16.035 (1)(c).
2. Review of Delineation. The reviewing authority shall compare the applicant's
delineation maps with the 1994/1995 ESEE Study and the SL Atlas, and shall inspect staked,
delineated resource boundaries. The reviewing authority shall approve the delineation if the
delineated boundary more accurately reflects the locations of RP and/or RC resources than the
boundary as shown in the SL Atlas. If the reviewing authority finds that the evidence is
contradictory or does not support the proposed delineations, the application shall be denied. In
the alternative, review of the application may be continued for additional information if:
a. The applicant agrees to conduct a new delineation by an expert selected by
the City Manager at the applicant's expense; and
b. The applicant waives the applicable statutory deadline for completing a local
decision on the application for the period of time necessary to conduct the new delineation.
3. Adiustment of Overlay District Boundaries to Reflect Approved Delineation. An
approved delineated boundary shall replace the boundary in the Sensitive Lands Atlas for the
purposes of review of the development proposal for compliance with this Article. If and when
the proposed development receives final approval, including resolution of any appeals, the
boundary of the RP or RC district as shown in the SL Atlas and SL Map (if necessary), shall be
modified to be consistent with the delineated boundary, and the SL Atlas and SL Map shall �% kw -
rise ry roll butT ,,.,twafd f'..em the delineate b I
u.aa, l�.�uu vu vurrc.
Since the "buffer" / "protected riparian area" is now included in the RP District, the map simply needs to
show the District.
4. Delineation not Required; Exceptions. An applicant for a development subject to
this Article shall not be required to delineate the resource pursuant to this section if:
a. The resource has been previously delineated pursuant to an earlier
development application subject to this Article. Exception: The City Manager may require a
new delineation if:
1. The applicant desires to demonstrate that the previously delineated
boundary is no longer accurate;
2. There is evidence of a substantial change in circumstances on the
property that has affected the location of the resource as previously delineated; or
3. The City Council has adopted new delineation standards or
requirements since the previous delineation, or
b. The proposed development consists solely of landscaping and/or tree removal
or qualifies as a resource enhancement project, and complies with LOC 50.16.075 (2)(a)(i)
[Landscaping], 50.16.075 (2)(ii) [Tree Removal], or either LOC 50.16.060 (3)(f) or 50.16.075
(2)(a)(vi) [Resource Enhancement Projects].
5. Delineation in the Absence of a Development Application. An applicant may apply
to delineate a resource in absence of an application for a specific development.

Section 50.16.040 Modifications to Dimensional Standards and Setbacks of the Underlying
Zone.
1. Except as provided in subsections (2) and (3) of this section, an applicant for
development subject to environmental review may vary from the lot dimensional standards
(building setbacks, lot size, lot width, and lot depth) otherwise applicable without a formal
variance pursuant to LOC Article 50.68, if the applicant demonstrates that:
a. Compliance with the applicable dimensional standard or standards would
cause the proposed development to disrupt lands within an RP or RC District within a ..o,,uirea
burr, or would preclude or reduce the transfer of allowable density from RP or RC zoned areas
Dt the property to non RP or RC zoned areas;
All references to overlay districts and their associated buffers are changed to overlay districts.
b. The proposed development will result in greater protection of the resources
identified on the site than would occur without the dimensional modification, and
c. In the case of a Planned Development, the criteria of LOC 50.17.015 have
been met.
2. An application to vary from standards other than the dimensional standards above or
that does not comply with the criteria contained in subsection (1) of this section may qualify for
a variance under LOC Article 50.68 or other applicable article or section for modification or
exception.
3. Where the request is not part of an application subject to the notice requirements of a
minor or major development (either LOC 50.8 1.010 or LOC 50.82.020), and the proposed
development would be located within 20 feet of an existing primary structure on abutting
property, written approval from the abutting property owner shall be required.
Section 50.16.045 Density Transfer.
1. Lot density transfer shall be permitted on residentially zoned lands subject to an RC
or RP District pursuant to this section.
2. Density Transfer Ratios.
a. Lot density (the number of lots otherwise allowable pursuant to the
underlying zoning designation but for the RP District and bufte ) may be transferred from RP
T • 1 1
uistnct ianas to contiguous non -resource zoned lands in the same ownership at a 1:1 ratio.
All references to 'overlay districts and their associated buffers" are changed to "overlay districts."
b. Lot density (the number of lots otherwise allowable pursuant to the
underlying zoning designation but for the RC Protection Area) may be transferred from RC
District lands to contiguous non -RC lands on the same ownership at a 1:1 ratio for the portion of
the RC District which is to remain undeveloped (the Protection Area).
3. When an applicant chooses to transfer lot density from one area or parcel to another
contiguous area or parcel, the area or parcel that is protected shall no longer be eligible for future
partition or subdivision. In order to put future property owners on notice, the applicant shall
execute a covenant running with the land that effects this restriction.

g. The Protection Area shall consist of viable plant and wildlife communities;
h. The Protection Area shall maintain the scenic qualities of the site.
4. It is recognized that all of the criteria listed in subsection (3) of this section may not
be applicable to every site. In some cases, the criteria may conflict on a given site. In such
cases, the reviewing authority shall balance the applicable criteria in order to protect the most
environmentally significant portion of the RC District.
5. Once a Protection Area has been identified and protected pursuant to LOC Article
50.16 and approval becomes final, no future reduction in the RC Protection Area shall be
permitted, unless the property owner files for a modification to the original permit and

This section defines the RP District as including the water resource and an adjacent protected
riparian area. This connects the resource and its riparian area, which serve similar purposes and
usually receive the same protections. It differentiates the District from the construction setback,
which lacks resource functions and values, and receives much less protection.
All references to "overlay districts and their associated buffers" are changed to "overlay districts";
"buffer" is replaced with "protected riparian area."

This states that the protected riparian area (formerly "buffer") has functions and values. This is
intended to clarify why the riparian area is protected. The protections were already in place, but the
reasons were not well articulated.
Changes below modify the language to apply the terms "stream or wetland" for the water feature,
"protected riparian area" for the 25-30' area around the water, and "RP District" for the stream or
wetland and its protected riparian area together.

Section 50.16.090 Special Standards for the Oswego Canal.
City of Lake Oswego Proposed Code Changes 21/26
Development Code Chapter 50.16 "Sensitive Lands"
09/27/10
I . Purpose. The Oswego Canal was originally constructed and continues to be used for
conveying water from the Tualatin River to Oswego Lake for the purpose of enhancing and maintaining
the lake. Although originally artificial, certain portions of the Oswego Canal have acquired the
characteristics of a RP Class I and Class 11 stream corridor. The Canal provides the primary source of
water to Oswego Lake for the purposes of recreation, navigation, scenic value, irrigation, maintenance
and enhancement of water quality and to produce hydroelectric power. It is also an important element of
flood and storm water control for Oswego Lake and surrounding areas and it serves as the route for a
sanitary sewer interceptor which is necessary to provide sewer service to several areas of Lake Oswego.
This section is applicable to the portions of Oswego Canal described as beginning immediately south of
the Bryant Road bridge and extending to the Tualatin River as illustrated by LOC Appendix 50.16-C.
These regulations are intended to preserve the community -wide benefits of the natural resource functions
and values of the Canal, but are not intended:
a. To prevent the Lake Oswego Corporation from exercising its water rights to
ensure an unimpeded supply of water to Oswego Lake;
b. To prevent the Lake Corporation from undertaking necessary management
and maintenance activities to ensure water quality of the Canal or Oswego Lake, or
c. To prevent the City of Lake Oswego or the Lake Corporation from repairing,
maintaining or making necessary improvements to essential public facilities and flood
management measures within the Canal per LOC Article 50.44 Flood Plain, applicable Federal
Emergency Management Association (FEMA) regulations, and any other City codes or standards
that are applicable.
2. Exempt Activities. The following activities within the Oswego Canal Stream Corridor are
exempt from the requirements of this Article when undertaken by the City of Lake Oswego or the Lake
Corporation:
a. Operation of the Oswego Canal headgate, including variation of water flow
rates and emergency or routine maintenance and repairs of the headgate, approaches to the
headgate, associated banks and channel including ripraped areas, reinforcement areas, gabions
and other features;
b. Emergency and routine removal of fallen trees, siltation, slides and other
debris from the channel and banks of the canal and buf4er protected riparian areas as needed to
ensure a continuous flow of water to Oswego Lake and to prevent flood damage;
On this page, all references to overlay districts and their associated buffers are changed to overlay
districts.
c. i reatment or waters or tlows of water for water quality purposes, and the
control or eradication of aquatic weeds and similar threats to the aquatic environment of Oswego
Lake;
d. Emergency and routine repair and maintenance of failing or collapsed sections of the
canal bank or bis protected riparian areas, including removal of contributing vegetation;
e. Maintenance, major repair of the Oswego Canal sanitary sewer interceptor
and any service laterals connecting to the sewer.
3. Activities Approved Pursuant to a Maintenance and Management Plan. Activities other
than those described as exempt above, or incidental thereto, shall be reviewed as a minor development
when proposed by the City of Lake Oswego or the Lake Corporation and when as part of an approved
maintenance and management plan. Activities approved pursuant to a maintenance and management plan
are subject to the minor development review criteria of LOC 50.79.025 and any other City Codes or
Standards that are applicable. These projects are exempt from the RP District requirements.

4. Environmental Mitigation Required. Any effects of the above activities in subsection (3)
which impact the Canal's stream corridor functions and values as determined by the adopted ESEE
analysis, when conducted as part of an approved maintenance and management plan shall be mitigated
pursuant to a plan approved by the reviewing authority. The mitigation plan shall be appropriate to the
scale of disturbance, conform to the Oregon Division of State Lands and the U.S. Army Corps of
Engineers requirements and shall also, to the extent practical, replace plant communities and wildlife
habitat disturbed by the above activities.
5. Boat Houses. Boat houses and docks shall not be placed within the portions of the Oswego
Canal : RP District as described in LOC 50.16.090 above and illustrated
by LOC Appendix 50.16-C.

Section 50.16.095 Construction Standards.
An owner shall submit a construction plan and narrative to the City Manager prior to any
grading, clearing, or construction on a development site which contains an RP or RC District.
The construction plan and narrative shall demonstrate that the following standards will be met:
1. RC Protection Areas or RC Districts where no protection areas have been approved
and RP District and buffers shall be protected during construction with either:
a. A minimum 6 feet tall chain link fencing secured with a minimum of 6 feet
tall steel posts. The fencing shall be in place and maintained for the duration of construction. In
addition, temporary signage shall be placed on the fencing which shall clearly identify the
resource District and shall state the penalty for violations of this Article:
or
b. Such alternative method to subsection (a) above that is approved by the City
Manager to demarcate and protect the RCPA or RC/RP District from the adverse effects of
construction activity upon the resources.
2. RC protection b ,,,.,,aafies delinea4ed feseafee b __ _ _ and
botindar-iesboundaries and RP District boundaries, as applicable, shall be located and staked by a
qualified professional prior to placement of fencing and other protective measures.
3. Hazardous Materials. The site shall be inventoried for hazardous materials, debris and
noxious materials, and these materials shall be removed prior to the development of the site.
4. No construction, demolition, grading, or site clearing shall begin until after
protective measures, signs, and erosion control measures are in place and have been inspected
and approved by the City Manager and all applicable permits have been issued. Fencing and
other protective measures shall not be removed, even temporarily, without the permission of the
City Manager.
5. No stockpiling of fill materials, or parking or storage of construction equipment shall
be allowed within a resource District.
6. When transportation facilities, pathways, utilities, or structures are approved within a
delineated RP fe District, they shall be constructed in such a way that a minimum of
excavation is required and so that no permanent draining or filling of a stream corridor or
wetland will occur.
City of Lake Oswego Proposed Code Changes 23/26

7. Surface runoff and other water sources supplying hydrology to an RP District shall
be designed and maintained so as not to adversely impact the functions and values of the
resource.
8. Any additional construction requirements imposed as conditions of approval or
which may be required by the Development Standards, the Lake Oswego Building Code (LOC
Chapter 45) or the Erosion Control Code (LOC Chapter 52).
[ Cross -Reference: Mitigation and Avoidance Review Requirements of LOC 50.16.100 to
50.16.110.]
Section 50.16.100 Mitigation; Purpose.
Purpose. Mitigation is a way of repairing or compensating for adverse impacts to the functions and
values of a natural resource caused by a development. Mitigation may consist of resource area creation,
restoration, or enhancement. Some examples of mitigation actions are construction of new wetlands to
replace an existing wetland that has been filled, replanting trees, and restoring stream side vegetation
where it is disturbed.
LOC 50.16.100 to 50.16.110 recognizes that true replacement of mature or complex natural
resource systems is difficult and can take many years. Mitigation is discouraged by first
requiring that avoidance of development siting within the resource be explored. Then, if that is
not possible, actions should be taken to minimize damage to the resource. Mitigation ratios are
established according to the type of mitigation proposed and the value of the resource.
Maintenance and monitoring of the mitigation measures4s are also required.

On this page, references to overlay districts and their associated buffers are changed to overlay districts.
1. Step #I Avoidance: The applicant shall endeavor to avoid detrimental impacts on the
resource altogether by providing alternative site plans along with the development proposal demonstrating
that alternative designs have been explored. If disturbance of a resource district resource is proposed, the
applicant shall first demonstrate that intrusion into the resource district cannot be avoided by a reduction
in the size or configuration of the proposed development or by changes in the design that would avoid
adverse effects on the resource while still allowing development of the property.
2. Step #2 Minimization: If the applicant has endeavored to avoid detrimental impacts on the
resource according to subsection (2)(a), above, and the review authority finds that detrimental impacts
cannot be avoided; then the applicant shall minimize impacts by demonstrating that:

Development Code Chapter 50.16 "Sensitive Lands"
09/27/10
a. Alternative and significantly different site plans and development locations
on the subject site have been considered, and that the alternative chosen is the least
environmentally damaging; and
b. When mitigation is proposed, there will be no net loss of resource area,
functions, or values as a result of development actions pursuant to LOC 50.16.110 (5) or (6),
whichever is applicable.
Section 50.16.110 Mitigation Requirements.
1. Mitigation Plan. When mitigation is proposed or required as part of a development
application, or when required or imposed as a result of a violation of this Code, the applicant shall provide
a mitigation plan prepared by a qualified professional that:
a. For proposed development, demonstrates compliance with LOC 50.16.105
and this section. For mitigation of violations of this Code, demonstrates compliance with LOC
50.16.105 (2)(b).
b. Includes a maintenance and monitoring plan. The maintenance and
monitoring plan shall include task timelines and quantitative goals to ensure the viability of the
mitigation over time. As part of the monitoring plan, the applicant or other legally responsible agent shall
provide an annual report to the City Manager on October 31st of each year for a 3 year period. The report
shall be prepared by a qualified professional and shall document site conditions with narrative and
pictures.
c. Provisions for regular maintenance and periodic monitoring of the mitigation
site.
Failure to comply with an approved mitigation plan shall be deemed a violation of this Code and
a public nuisance and may be enforced pursuant to LOC Articles 34.04 and 34.08.
2. If a Division of State Lands (DSL) wetland permit, Army Corp. of Engineers, or
other State or Federal permit is also required, the City shall not issue a building permit until all
applicable State and Federal wetland permit approvals have been granted.
3. Mitigation shall be completed prior to a final inspection, issuance of a final
occupancy permit, or acceptance of a public improvement.
4. On-site mitigation is required where possible, taking into consideration the existing
natural and human -made features of a site. If the review authority finds that on-site mitigation is
not possible, then off --site mitigation shall be permitted according to the following priorities:
a. Within the same drainage system (as defined by the Lake Oswego Surface
Water Management Plan or the Winterowd Natural Resources Inventory) and within the City
limits; or
b. Outside of the drainage system, but inside the City limits; or
c. Outside the drainage system and City limits, but within the Lake Oswego
Urban Services Boundary.
5. Stream corridors and treerg_oves: When mitigation is proposed, the review authority shall
require a minimum mitigation ratio (area of resource District created or enhanced to area of resource
District lost) of 1:1 for stream corridor and tree grove resources.
6. Wetlands: When wetland mitigation is proposed within an RP Class I or Class II District,
the review authority shall require minimum mitigation ratios (area of wetland created or enhanced to area
of wetland lost) as follows:
a. Wetlands Creation or Restoration - 2:1 ratio
b. Wetlands Enhancement - 3:1 ratio
City of Lake Oswego Proposed Code Changes 25/26
Development Code Chapter 50.16 "Sensitive Lands"
09/27/10
c. Wetlands Creation, Restoration or Enhancement- 5:1 ratio where the wetland
is a Class I RP District and is forested or contains a sensitive, threatened or endangered species
as identified in an adopted ESEE inventory.
7. Vegetation restoration shall be required to mitigate the loss of plant communities
disturbed by development activities. In-kind vegetation shall be required for all mitigation
projects, including trees, shrubs, and ground cover plants as identified on the Plant List (on file
in the Planning Division). The restoration plant community chosen shall recreate a diverse and
healthy environment which is compatible with the resource.
8. Initial 3 Year Bonding Period.
a. Except as provided in subsection (8)(d) of this section, the applicant or
property owner of a development subject to an approved mitigation plan shall post a performance
bond or a letter of credit to the City that is equal to 120% of the value of the improvements
installed pursuant to the plan for a 3 year period. The bond shall be posted prior to the issuance
of a building permit to ensure the success of mitigation improvements and the survival of plant
materials.
b. The performance bond or the letter of credit will be released by the City after
three (3) years upon receiving proof that the mitigation measures have been successfully
implemented according to approved plans. Following release of the financial guarantee, the
property owner(s) or other designated party (such as a homeowners association) shall remain
responsible for maintenance of the resource.
c. If mitigation improvements fail during the bonding period and the responsible
party does not replace said improvements after notification by the City, the bond shall be
forfeited and shall be used by the City to correct the problem pursuant to the Mitigation Plan and
the Conditions of approval.
d. Property owners of individual tax lots that are lots of record which are zoned
for single family residential use, are not large enough to be further divided, and were in existence
prior to the date this Article becomes effective shall be exempt from these bonding requirements.
50.02.05 "Definitions"
Ditch: A manmade water conveyance channel. Channels that arc manipulated streams are not
hes.
This is exactly the definition used by the Department of State Lands; see OAR 141-085-0510. Using the
DSL definition means the DSL could advise the City if we were unable to determine whether a channel
was a ditch or not.
Protected Riparian Area: The area adjacent a water resource described in LOC 50 16 070 (2)

This definition uses the same language as 50.16.070(2). This definition is included to clarify that the
Protected Riparian Area provides its own functions and values and also protects the adjacent resource
area.

12
13 The Planning Commission concludes that LU 10-0043 is in compliance with all applicable criteria.
14
15 FINDINGS AND REASONS
16
17 The Planning Commission incorporates the staff report, dated September 16, 2010, on LU 10-0043 (with
18 all exhibits attached thereto) as support for its decision, supplemented by the further findings and
19 conclusions set forth in this document. In the event of any inconsistency between this supplementary
20 matter and the staff report, this matter controls. To the extent they are consistent with the approval
21 granted herein, the Commission adopts by reference its oral deliberations on this matter.
22
23 Following are the supplementary findings and conclusions of this Commission:
24
25 1. The Lake Oswego City Council has adopted Resolution 10-51A, which contains the Council's
26 goals for improving the City's Sensitive Lands Article and other environmental programs. The
27 City's application is in furtherance of Resolution 10-51A Section A, Goals 1 and 2.
28
29 2. Much of the public testimony provided at the September 27th hearing related to concerns about
30 the Sensitive Lands Article ("Article") overall, and to issues addressed in Resolution 10-51A that
31 are beyond Section A, Goals A(1) and A(2). The scope of the application before the Planning
32 Commission was limited to the amendments proposed.
33
34 3. The Commission finds that simplifying this Article by the amendments proposed, and allowing
35 development with de minimis impacts to the resources is intended in part to reduce the
36 perceived burden of the Article, and thereby encourage residents to understand the Article and
37 seek to voluntarily comply with its provisions. This in turn should increase overall code
38 compliance, and result in greater benefits to environmental resources.
39
40 4. The Lake Oswego Comprehensive Plan recognizes the goals of:
41 a. Preserving and restoring environments which provide fish and wildlife habitat (Goal 5,
42 Section 1, Goal);
43 b. Protecting and restoring the community's wooded character and vegetation resources (Goal
44 5, Section 2, Goal);
45 c. Protecting, maintaining, enhancing and restoring wetland (Goal 5, Section 3, Goal).
46 d. Providing for economic development opportunities which enhance the prosperity and
47 livability of the community (Goal 9).
48 e. Providing for needed housing while protecting environmentally sensitive areas (Goal 10(c))
LU 10-0043 PAGE 2
2 Each of these goals have policies which implement the goal (see Paragraph 5 below). In some
3 cases the policies require "maximization" of efforts, e.g., developers are required to maximize
4 protection of the "natural functions and values." In other cases, polices are stated without
5 quantification, e.g., policies require the City or developers to "protect, restore, maintain"
6 without a numerical threshold or quantification of the preservation efforts.
7
8 5. The Commission finds that de minimis intrusion into resource areas do not appreciably affect
9 the functions and values of the resources, while still permitting reasonable development
10 opportunities. Further, when examining proposed amendments to the Community
I1 Development Code, and their conformance with the Lake Oswego Comprehensive Plan policies,
12 the Commission notes that maximization of the various policy objectives is required within the
13 context of the Comprehensive Plan and Statewide Planning Goals. See Lake Oswego
14 Comprehensive Plan, Introduction, Definitions and Obligations of Goals, Policies and
15 Recommended Action Measures, Section II Policy, "Obligation".
16
17 6. The City's Comprehensive Plan policies promote limitations on development and tree removal in
18 tree groves and riparian buffers in Goal 5, Section 1, Policies 1(a, c, d, e), 4(a, b, c, d), and 6;
19 Section 2, Policies 1, 2, 3, 9, and 14; Section 3 policies 1, 3(a, b, c) 6(b) and 9; Section 4 Policies
20 1, 3, 4(a, d), 7(a) and 13; Section 5 Policies 1, 5(a, b, d, e), 9(a, b); and Goal 6, section 1, policy 3
21 and section 2, policy 6. DLCD's Statewide Planning Goals 5 and 6 require the City to adopt and
22 maintain a program that protects natural resources, in order to promote a healthy environment
23 and natural landscape that contributes to Oregon's livability and improve the quality of the air,
24 water and land resources of the state. Metro Titles 3 and 13 require a City program for water
25 quality, flood management, ecologically viable streamside corridor system, integrated with
26 upland wildlife habitat and with the surrounding urban landscape; and prevent water pollution
27 and improve water quality throughout the region. The City's protection of trees in riparian and
28 upland habitat areas is one mechanism the City employs to achieve compliance with Goals 5 and
29 6, and Titles 3 and 13.
30
31 7. The Commission finds that de minimis impacts to natural resources, by their nature, do not
32 appreciably degrade the resource, when considering the entire resource within the city's
33 jurisdiction, and therefore, by their nature, do not lessen the preservation and protection of the
34 natural resources' contribution to the environment and natural landscape.
35
36 8. The Commission finds that amendment of the Sensitive Lands Article to allow removal of trees
37 for new development of up to 200 square feet in the RC or RP districts will have a de minimis
38 impact because:
39
40
a. The ability to site development requiring tree removal will be constrained by the
41
Tree Code requirements for tree removal. If the proposed development of up to
42
200 square feet is proposed in an area where tree removal would be necessary, the
43
City's Tree Code (LOC Article 55) will apply: If the tree proposed for removal would
44
have a significant effect on the character, aesthetics, or property values of the
45
neighborhood, landowners must demonstrate that alternative development
46
locations have been considered to minimize tree removal. A tree removal permit
47
would require public notice, staff review, and an opportunity for appeal, to ensure
48
that the criteria for tree removal have been met.
LU 10-0043 PAGE 3
b. With a cumulative total of 200 square feet of development, an alternative location
could be found on most sites, thus lessening the number of tree removal permits
sought to site small (< 200 sq. ft) developments.
c. Considering the small numerical number of tree removal permits that may be
obtained, the impact upon the overall area of the tree canopy within the City is
expected to be negligible.
The Commission concludes, therefore, that the tree removal permitted by these changes will
have an insignificant impact on overall tree cover in tree groves and riparian areas, and that the
proposed amendment complies with the Lake Oswego Comprehensive Plan, Goal 5 policies cited
above.
9. The Commission finds that development is limited in natural resource areas because it impacts
resource functions and values in a variety of ways, such as by the presence of people and pets,
lighting, noise, and use of biocides and fertilizers. The physical displacement of habitat caused
by a dwelling unit is only one element of its total environmental impact.
10. Allowing the footprint of an existing dwelling to be increased by up to 700 square feet with the
limitations described below will have a de minimis impact because:
a. Additions are allowed only to existing primary residential structures; additions will
not allow new residential uses to be established in the resource area.
b. Additions will not be closer to the resource area than the pre-existing use.
c. The size of additions are limited by other factors including lot coverage,
architectural/ design considerations, and setbacks.
d. Metro, following enactment of Titles 3 and 13, concluded that 500 square feet
additions to structures — all structures —have a de minimis impact upon the natural
resources of a jurisdiction. See Metro Model Code, quoted in Exhibit E-2. The
Commission concurs with Metro's conclusion.
e. Additions to existing primary residential structures will be limited when considering
that the opportunity to expand will be limited by internal configuration of
residences.
f. The Commission finds that an additional 200 square feet expansion area, although
not identical to Metro's 500 square feet de minimis expansion, will similarly have a
de minimis impact upon the natural resources, particularly when considering the
limitation on the type of structure (primary residential v. any structure) and internal
configuration limitations (adding an additional 200 square feet beyond 500 square
feet will present less opportunities for full expansion due to the layout of residence
and the prohibition against expanding closer to the resource).
The Commission concludes that the primary residential additions permitted by these changes
will have a de minimis impact on upland or riparian habitats, and that the proposed amendment
complies with the Lake Oswego Comprehensive Plan, Goal 5 policies cited above.
45 11. The Commission finds the existing Sensitive Lands Article allows repair and replacement of
46 utility lines in resource areas when there is no other practicable alternative. See LOC
47 50.16.060(3)(g) and 50.16.075(2)(a)(iii). Because of the necessity that the portions of utility
48 lines within a resource area be connected to the utility lines outside the resource area, in most

instances it is not practicable to relocate utility lines outside of a resource area in order to repair
or replace utility lines within a resource area.
The Commission further finds that repairs and in-kind replacement of existing utilities and
placement of individual service lines typically involve a narrow width of intrusion into a resource
area, and the abutting, undisturbed resource area will assist in recovery of the disturbed area.
Further, restoration of the disturbed area will be required.
The Commission concludes that repairs and in-kind replacement of existing utilities and
placement of individual service lines can reasonably be expected to be de minimis to the effect
upon the entirety of the resources areas within the City, and that the proposed amendment
complies with the Lake Oswego Comprehensive Plan, Goal 5 policies cited above. However, the
Commission concludes it is not possible to determine the impacts of the construction of new
utility lines without additional information. Therefore, an unlimited permission to construct
new utility lines is not warranted.

RESOLUTION 10-51A
A RESOLUTION OF THE LAKE OSWEGO CITY COUNCIL DIRECTING STAFF TO IMPLEMENT
REVISIONS TO THE CITY'S NATURAL RESOURCE PROTECTION PROGRAM
WHEREAS, in the 1990's, in an effort to protect significant natural resources as called for
by the City's Comprehensive Plan and Statewide Land Use Planning Goals 5 and 6, the
City indentified and mapped significant resource areas, and in 1997 adopted regulations
known as Sensitive Lands regulations; and
WHEREAS the City anticipated that, with certain modifications, the Sensitive Lands
regulations would qualify for compliance with Metro's Title 3 and 13; and
WHEREAS the Sensitive Lands regulations have not been significantly amended or
modified since adoption; and
WHEREAS concerns and questions raised by the community led the City to conduct a
thorough review of the program by supporting the Planning Department in convening a
technical task force (the Second Look Task Force) to evaluate the Sensitive Lands
program and recommend program improvements; and
WHEREAS, from September 2009 to May 2010, after 17 meetings, one Public Open
House and Comment Session, and including field trips, case studies, presentations and
extensive document review, the Second Look Task Force compiled recommendations for
program improvement, which were presented to the Planning Director and reviewed
and evaluated by the City Council; and
WHEREAS, following three public comment sessions in review of Task Force and staff
recommendations held in June and July 2010, the City Council is prepared to direct
program revisions with a goal of offering greater flexibility for property owners, while
maintaining environmental protection and compliance with Metro and State standards;
BE IT RESOLVED by the City Council of the City of Lake Oswego as follows:
The City Council directs staff to prepare the following program revisions (as outlined
more thoroughly in the Staff Report dated July 15, 2010 and in the Second Look Task
Force Report dated May 28, 2010):
Section A: Implement the regulatory changes identified in Staff Report Section A, which
recommends immediate amendments to:
1. Modify the Development Code to permit de minimis impacts, with specific
attention to allowing more uses in buffers, such as fences, gardens, lighting,
pervious surfaces, etc.
Resolution 10-51A EXHIBIT F-1
Page 1 of 3 LU 10-0043
2. Clarify the terms "ditch," "resource buffer," and "construction setback"
3. Exempt invasive trees from tree removal permit requirements
4. Amend the City fee schedule to eliminate the resource delineation fee
Section B: Implement the regulatory changes identified in Staff Report Section B within
the next year, including the following steps:
1. Develop and initiate a free map correction process
2. Consider removing small, isolated tree groves from the overlay zone on private
property, not including private dedicated open space
3. Improve the readability of the Sensitive Lands code
4. Develop a two -track review system
5. Develop standards for mitigation measures
6. Direct staff to return to Council with habitat friendly development codes
Section C: Return with a supplemental budget request for the enhanced communication
and community outreach activities identified in Staff Report Section C as follows:
1. Expand Landscaping for Conservation outreach and education programs
2. Develop a handbook on best practices for restoration; provide some on -the -
ground support and grant opportunities
3. Develop new informational materials for property owners
4. Strengthen the City's connection to watershed councils and seek their assistance
in these outreach efforts.
Section D: Schedule study sessions on the new resource protection and environmental
initiatives identified in Staff Report Section D as follows:
1. Direct staff to report to the City Council by February 1, 2011 on advantages,
disadvantages, funding mechanisms and an implementation plan to organize and
operate internal resources to support watershed based environmental

SUBJECT: Lake Oswego Text Amendment — Utility Line Exemption
DATE: November 1, 2010
FAQ t IQ i Ll
This report is for information only; no action is requested at this time. A public hearing on this topic is
tentatively scheduled for December 13, 2010
INTRODUCTION/BACKGROUND
The following is a summary of the proposed Lake Oswego text amendment which provides a Utility Line
Exception in designated sensitive land areas. This exception would allow the placement of public utility
lines in designated sensitive areas without being required to go through a land use approval process. The
applicant would still be required to delineate and mitigate, according to Lake Oswego Code, for any
disturbance in these areas.
Public utilities provide vital water, wastewater and surfacewater infrastructure services to the community.
As the community grows, and/or service needs change, their routes and required improvements are
typically determined by population growth patterns, available space, ground topography and life -cycle
costs. Being required to go through the land use approval process to permit these utility improvements
costs the City time and money in preparation and review for projects which the location and size of the
improvement are generally predetermined. No additional detrimental effects to the sensitive land areas
would occur without the land use review as the mitigation for any disturbance is still required to comply
with existing City Code.
Planning Commission Concerns
In September 2010, the Lake Oswego Planning Commission (PC) held a public meeting to listen to various
Page 2
proposed development code text amendments. At this time the PC had a pretty specific objection to the
utility line exception. Their objection was that they were concerned about large public or private utility
lines being located in sensitive land areas without City oversight and approval. Because of this concern, the
PC voted to not approve the utility line exception as staff had proposed. It may not have been
communicated to them that all utility operators can now locate their improvements in sensitive land areas,
if the areas are unavoidable, as long as they mitigate for the disturbance according to City Code. One
possible remedy to the PC's concern would be to narrow the exception so that it only applies to public
utility operators. If only public utility operators are allowed to use this exception the City can have
confidence that any improvements that are made to the public infrastructure are necessary.
Proposed Text Amendment
The proposed code language is an example of how the amendment could be written that would allow the
City to accomplish its public works goals while protecting the sensitive land areas. (Proposed change is in
BOLD)
Section 50.16.015 Applicability
1. This Article applies to all lands designated as RP or RC on the Sensitive Lands Map and Atlas.
2. Sensitive Lands Development Review Required.
3. Exception: The provisions in LOC Article 50.16 shall not apply to:
a. A resource located within the boundaries of a partition, subdivision, Planned Development,
or lot line adjustment, approved prior to August 21, 1997 if:
i. The resource was identified and protected pursuant to regulations in effect at the time of
approval; and
ii. The proposed development is in compliance with the conditions protecting the resource
imposed at the time of approval. Any modification of the prior approved partition, subdivision, or
planned development that would impact or modify any protection measures imposed at the time
of original approval shall be subject to the standards and criteria of this Article.
b. Resource restoration required as a result of violation of this Article or pursuant to
settlement of a potential enforcement action by the City Manager, subject to City Manager
approval of the restoration plan and procedures, and compliance with the Construction Standards
set forth in LOC 50.16.095.
c. Development that meets all of the following criteria:
i. The development does not result in any new permanent structure or development within
the RP or RC District, or its associated buffer, except the replacement or vertical expansion of an
existing non -conforming structure, within the footprint of the non -conforming structure; and
ii The development does not remove any vegetation designated as native vegetation in the
Lake Oswego Plants List; and
iii. All replacement vegetation used is listed as "native vegetation" in the Lake Oswego
Plants List.
d. Utility Line Exemption - Repair and replacement of existing utility lines and utility line
appurtenances and new utility lines and utility line appurtenances if they are located in an
existing utility easement or in improved public right-of-ways where:
i. The disturbed portion of the resource district is restored according to City Code; and
Page 3
ii. Non-native vegetation is removed from the impacted resource area and is replaced
with native vegetation from the Lake Oswego Plants List in accordance with LOC
50.16.110.
This proposed change is respectfully requested by Public Works Department, and supported by the
Planning and Building Services Department. Staff feels that this change will allow the City to permit its
utility improvements, which are located in sensitive land areas, in a more efficient, timelier and more cost
conscious manner without creating any greater harm to the designated sensitive land areas in Lake
Oswego.
ALTERNATIVES & FISCAL IMPACT
Utility service lines are intended to be planned, designed, constructed, operated and maintained
sustainably, resulting in reliable, lowest life -cycle costs for services. As was mentioned earlier, the
expansion of services to serve growth and/or modification(s) to improve existing services requires taking
advantage of ground topography "gravity" and/or relational (i.e. close proximity) efficiencies. The
construction of utility lines within environmentally sensitive lands only makes since when this option is the
only viable, practical and sustainable option available. The fiscal impacts to alternative utility service line
alignments (outside of environmentally sensitive areas) can be significant, including additional material
costs, energy costs (pumping systems and "back-up" electrical systems), operational and maintenance costs
as well as resulting in potentially less reliable (especially when compared to "gravity" systems) services.
RECOMMENDATION
The Public Works Department recommends that Council thoughtfully consider the requested text
amendments (as noted in this memo) and incorporate them with the other staff proposed text changes to
LOC 50.16 "Sensitive Lands".

To: Lake Oswego Planning City Council
From: Andrew Harris
Subject: Proposed Changes to LOC 50.16 "SENSITIVE LANDS"
The following comments are presented to follow the counci report formatting and page
numbering.
INTRODUCTIIONBACKGROUND
Resolution 10-51A Section Al states "Modify the Developr_:ent Code to permit de
minimis impacts, with attention to allowing more uses in bv.,f¢ers, such as fences,
gardens, lighting, pervious surfaces, etc."
"De minimus" means "lacking significance or importance_.- so minor as to merit
disregard" as defined by the Merriam -Webster dictiona-�,y-.
DISCUSION SECTION
Allow de minimis impacts
No. 4 - FENCES (page 7)
Facts:
1. The proposed change allows fences in wetland and t -I .-low the top of bank of a
stream.
2. The proposed change does not mention allowing feir::es in buffers.
3. The consequence will be significant and important n.-: tgative impacts to the natural
functions of wetlands or streams.
4. These natural functions include:
• Conveyance of normal and flood flow
• Conveyance of stream sediment load
• Conveyance of wood and other floating materiab
• Flood storage and flow attenuation (reduction of ?cak flows)
• Stream bank stability and erosion control (aided riparian vegetation)
• Temperature regulation by water quality benefits ,'Y-om shade and vegetation
filtration
• Hydrology that supports riparian vegetation and !.. sociated wetland
• Wildlife habitat, including food, shelter, nesting. ;end breeding opportunities
• Movement along a stream and adjacent to it for 1-. bitat resources

Considerations:
1. The important questic-:s to ask are:
• What are the impacts'.
• D the impact `lack si ificance or importance"? and
• What is the best wa-y- allow the proposed use while avoiding, minimizing, or
mitigating for the in-.rzts?
2. Floodways and floo6 - :-one areas are almost always outside the bank of the
stream. The exceptic-L 3 when the stream is severely degraded by channel
incision.
3. Fencing in a stream...:tland, or associated flood prone area does not make sence.
If a property owner �1ts a fence to provide security or confine your pets, having
an opening for wildii. would defeat that purpose.
4. Fencing all the way 'he ground across a stream would provide security but the
impacts to the owner": -)roperty and adjacent property would be far greater than
"de minimis".
Recommendations:
1. Do not allow fences ithin a wetland or top of bank of a stream.
2. Do not allow fences flood prone areas.
3. Do not allow fences 2... potential flood prone areas adjacent to streams that
are degraded by ch.:: nel incision.
4. Allow fences adjace._ to but not crossing wetland, stream, and associated
flood prone areas p7Aded the impacts to natural functions are truly
insignificant.
5. Provide gates in the : ince to allow access to the resource areas when desired.
Justifications:
1. Impacts are not "de imn _.imis" as directed in Resolution 11-5 1 A, Section A.1
2. Fences would be in _ream or wetland, NOT in a buffer as directed in
Resolution 11-5 1 A, S,:; tion A.1
3. The Second Look tas' orce did not recommend fences or other sues in stream or
wetland resource area-,-.
4. FEMA standards prof: Siting development in a floodway and requiring restrictions
in the floodway fringe: is a factor to consider before allowing development in
these areas.
No. 5 - UTILITY LINE Exemption
Considerations:
1. The permit process provides a way to assure that we protect and conserve natural
resources.
2. The utility line exemption creates a double standarc'. especially when allow an
exception for city new construction
3. The City even requires a permit to do resource enhancement projects. Do we
want to exempt something that could and has in the 'east had sever impacts to
streams and wetlands.
4. Make the process expedited and reasonable for all p�::rmits.
5. Is this exemption "Leading by Example? I think not.
6. State and federal permits may still be required anyway.
Recommendation:
1. Do not allow utility line exemptions for repair, replo;,ement or new construction
of utility lines.
NOTE WORTH INFORMATION
1. Stream Morphology
Streams are more than just stream channels defined by t-L3e top of bank. A stream's
riparian and flood prone areas (floodplains) are also req -.-fired for the proper function
of stream systems. See Figure #1 and photo # 1.

2. Impaired Stream Conditions
One noteworthy consideration is the impaired condition of many urban streams.
Unfortunately, this is a common condition. Impaired streams typically have limited
ability to provide natural functions. Imbedded in federal. state, and local regulatory
programs is the understanding that for streams to be healthy they must properly
perform their natural functions. See Photos #2, #3, and :4.

Dear jonna:
Thank you for the opportunity to review the City of Lake Oswego Planning Commission recommendations
related to a text amendment to LOC 50.16 Sensitive Lands; file LU 10-0013-1745. In general, Metro staff
feels that the proposed text amendments are in line with the intent of Urban Growth Management
Functional Plan (Functional Plan) Title 13: Nature in.Neighborhoods; however, we have some concern
regarding one of the Planning Commission's recommendations.
Specifically, we are concerned with the Planning Commission's recommelydation to increase from 500
square feet to 700 square feet the amount of intrusion that could occur in a resource area that would be
exempt from the requirements of the Sensitive Lands Ordinance as a resu It of an alteration, expansion or
replacement of an existing primary dwelling unit as outlined in LOC 50.16.015(4), Metro's Title 13 Model
Ordinance allows for the alteration, expansion or replacement of a structure that will not intrude more
than 500 square feet into the resource area to be exempt from the Title 1:i regulations. The Model
Ordinance was developed by a subcommittee of Metro Technical Advisory Committee members, including
a representative of the City of Lake Oswego. Based on their collective planning and development
experience, the subcommittee felt that 500 square feet was a reasonable amount of intrusion that would
balance the negative impact to the resource while providing some opportunity and flexibility for an
applicant. The 500 square foot limit has been adopted by the other jurisdictions in the region that are in
compliance with Title 13.
We propose that the City of Lake Oswego develop a discretionary process as recommended by the Lake
Oswego Second Look Task Force to complement the existing process contained in LOC 50.16. A
discretionary process could provide the opportunity for an applicant to propose an additional amount of
impact beyond 500 square feet for those limited number of situations where the existing primary structure
already intrudes into the resource area. This process could still provide flexibility while providing greater
overall protection for the City's natural resources.
I understand that the Planning Commission also discussed the requirements of LOC 50.16 as they relate to
utility work. Metro staff concurs with the Planning Commission's decision to provide an exemption for the
repair and replacement of existing utility lines and utility appurtenances if they are located in existing
utility easements or in improved public rights of way, while not providing; an exemption from the
requirements of LOC 50.16 for new utility projects. This determination by the Planning Commission is
consistent with Title 13.

As you know, any successful natural resource protection. program includes an educational and voluntary
incentive component that complements the formal protection requirements. Accordingly, Metro looks
forward to partnering with the city to promote education and outreach efforts such as your current
partnership with Friends of Tryon Creek State Park and Tryon Creek Watershed Council. Furthermore,
Metro's Nature in Neighborhoods Restoration and Enhancement Grant Program for 2011, which supports
hands-on activities and environmental education programs that protect and contribute to watershed
health, is currently underway and information regarding the program can be found at

MAYOR and CITY COUNCIL
City of Lake Oswego
RE: FENCES
Proposed Changes to LOC 50.16 "Sensitive Lands"
City of Lake Oswego, Clackamas County, Oregon
Mayor and City Council:
An item on the agenda of your meeting tonight considers "Proposed Changes to LOC 50.16
Sensitive Lands", specifically fences. I have discussed the matter with Andy Harris, a member
of the Second Look Task Force. Andy and I have known each other for quite a few years. We
don't agree on all issues concerning the Sensitive Lands Ordinance; but, we do agree on some
very basic issues concerning the construction of fences on private property.
Item 4 of the staff report, page 7 of the agenda packet, states "Fences located within a Wetland or
below the top of bank of a stream, ..."
In my opinion, as a Registered Professional Engineer, and as an engineer holding a
Master of Science degree in Civil Engineering, with a major in Hydraulics, there is no
reason the City should propose an ordinance which specifically allows construction of a
fence below the bank of a stream. Also, the ordinance should not specifically allow
construction of a fence within the floodway of a stream. It simply makes no sense; and,
indicates poor judgment. A fence should not be constructed where it will impede the
natural flow of a stream under normal conditions or flood conditions. A fence could
create a barrier to the flow of water in a stream and be the cause of flooding.
Also, in my opinion, the City should not propose within an ordinance that construction of
a fence within a wetland is an acceptable practice. It just makes no sense.
In addition, item 4 goes on to say "... when the fence is constructed so that for each 100 feet or
portion thereof of fencing, at least one 2 -foot section is:
i. Not less than 12 inches above the surface, and
ii Not more than 4 feet tall from the surface."
This, in my opinion as a property owner, and as a father that has raised three children,
and as someone who has had dogs and other animals running on their private property, is not
what the City should try to require and/or limit on private property. The purpose of a fence is to
contain children and family pets on your own property. You simply cannot achieve your
objective when the City tries to control the design of fencing on your private property. It makes
no sense; and, the City is over -stepping reasonable property controls.

SUBJECT: Invasive Tree Species to Exempt from Tree Removal Requirements
DATE: October 28, 2010
ACTION
This report is for information only; no action is requested at this time. A public hearing on this topic is
tentatively scheduled for December 13, 2010. Review staff recommendations to exempt invasive tree
species from the City's tree removal permit requirements pursuant to Resolution 10-51A, and direct staff to
develop code language modifying LOC Chapter 55 "Trees". In addition, provide direction on Council
priorities in developing a schedule and process for future tree code considerations.
INTRODUCTION/BACKGROUND
Trees are a dominant visual element in Lake Oswego and also provide a wide array of social, economic, and
environmental benefits. "Trees not only beautify streets and neighborhoods and provide wildlife habitat,
they also function to increase water, air, and soil quality and provide tangible economic benefits to
homeowners and commercial districts."'
The City-wide tree canopy cover for Lake Oswego is 44.4% as described in the June 2009 State of the Urban
Forest Report. This is one of the highest percentages of canopy cover in the Metro region and surpasses the
American Forest Foundation's recommended average 40% canopy cover for Pacific Northwest cities.z For
the last 21 years, Lake Oswego has been recognized as a Tree City USA, which is a special program of the
National Arbor Day Foundation that recognizes cities that meet standards set for tree planting and care.

Chapter 55 of the Lake Oswego Code (LOC) regulates the removal of trees in the City and stipulates
protection measures to preserve trees during construction. The tree code works well to protect individual
trees throughout the City, but does little in regard to the overall health and sustainability of the urban
forest. The purpose of the tree code is to "protect trees as a natural resource of the City." In recognizing
that certain tree species are becoming increasingly invasive in natural areas, and in an effort to better
manage the overall health and sustainability of the native ecosystem, removal of invasive species ought to
be encouraged by the tree code.
Invasive species are broadly defined as species that were introduced by humans to locations outside of
their native range that spread and persist over large areas, outcompeting native species. More information
is included in the attached handout "What the heck is an invasive plant?" produced by the Plant
Conservation Alliance.3 Invasive species negatively impact natural ecosystems by displacing native species,
reducing biological diversity, interfering with natural succession, and more.
On July 20, 2010, the Lake Oswego City Council adopted Resolution 10-51A, directing staff to implement
revisions to the City's Natural Resource Protection Program. Section A, Item 3 states, "Exempt invasive trees
from tree removal permit requirements." International Society of Arboriculture (ISA) Certified Arborist
Morgan Holen (PN -6145A), working as Assistant Natural Resources Planner for the City, conducted research
about invasive tree species and contacted local arborists to request feedback pertaining to invasive trees.
This report recommends specific invasive tree species to exempt from the City's tree removal permit
requirements, and further provides considerations for future tree code updates.
DISCUSSION
First, tree species believed to be invasive in the Pacific Northwest were researched. The City of Portland has
a widely accepted list of nuisance tree species that are invasive and "threaten the health and vitality of
native habitats, humans, and cause economic harm to public and private landowners" (Portland Plant List,
page 4-1). The tree species listed in the Portland Plant List provided a starting point. Other resources used
include a draft list of invasive species prepared by Clean Water Services, and tree species reported to be
invasive by the Native Plant Society of Oregon and the Plant Conservation Alliance.
Additionally, the City sent an e-mail to 33 ISA Certified Arborists who work locally in and around Lake
Oswego in order to solicit feedback regarding the exemption of invasive tree species from the City's tree
removal permit requirements. A list of arborists that were e-mailed is enclosed. Eight (24%) arborists
responded with comments and suggestions, which were considered in developing these recommendations.
Invasive Tree Species to Exempt from Regulations
Twelve tree species are deemed invasive by one or more professional organizations and are recommended
for exemption from the City's tree removal permit requirements outright. These invasive tree species are
described individually in Table 1 (next page).
The City can encourage the removal of invasive tree species by exempting these species from the tree
removal permit requirements. This change is not intended to force the removal of invasive tree species on

private properties if property owners do not want to or cannot afford to. The City should take an active role
in the removal of invasive tree species from public properties during routine maintenance and when
developing long-term management plans for parks, open spaces, and natural areas.
Special Considerations. Exempting some trees from the tree code raises issues about mitigation
requirements and limitations to the exemptions. Staff makes the following observations and
recommendations:
• Invasive tree species should no longer be accepted when proposed for planting as part of a
development application landscape plan or mitigation plan.
Replacement for invasive tree species removal should be required in public rights-of-way (ROWS),
Resource Protection (RP) Districts, and where removal of invasive tree species is associated with a
previously approved development or as mitigation for an earlier tree removal permit. Replacement
plantings are especially important in public ROWS and in RP Districts because of the special value of
trees that are intercepting stormwater over paved areas (preventing stormwater pollution) and
shading water resources (preventing temperature pollution). Additionally, the City should allow the
replacement rather than removal of invasive tree species that were previously required to be
planted as part of an approved development or for mitigation. The number of replacement trees
should be determined by the number of trees removed. If the available planting space is a limiting
factor for the successful establishment of replacement trees, replanting may be proposed at
another location in order to meet the replacement requirements. No required replacement is
proposed for the removal of invasive tree species located outside of public ROWS or RP Districts and
not associated with previously approved development or mitigation. Nevertheless, in recognizing
the benefits of trees regardless of their location, the City should encourage replacement plantings
on private properties and provide education and outreach to help people make informed choices
about planting the right tree in the right spot.
Prior to the removal of an exempt invasive tree, the property owner must positively identify the
tree as an invasive species. Some species are more difficult to distinguish from native` varieties, but
there are unique characteristics that can help and the City can prepare a guide to help the public
and staff with species identification. The City could offer free identification to people that call for
assistance, which will also promote one-on-one interaction between the City and property owners
and an opportunity for education and outreach. If a tree cannot be positively identified as an
invasive species, that tree should not be considered exempt.
In addition to developing a photographic manual to aid invasive species identification, the City could
also provide property owners with information about tree removal, including techniques to help
control sprout growth for species that reproduce vegetatively from stumps and roots. Staff could
develop a brochure to attach to the verification letter and to tree permits generally with
information on tree removal, new tree selection, planting, care and maintenance, and the benefits
of trees.
Provision of additional services such as tree identification, one-on-one interaction, developing brochures
and additional education and outreach materials, all have budget implications because they would require
additional staffing.
Verifying and documenting that a removed tree is invasive is a critical issue. The City could either (A)
provide a free permit process to verify and document the removal of invasive tree species, or (B) give
property owners the responsibility to properly identify and document invasive species prior to removal, so
Page 5
as to avoid challenges by neighbors or other interested parties. The former would essentially be a free
permit, which would require staff time but help to ensure proper species identification and documentation
prior to removal. The latter would result in less staff time in most cases, but places the responsibility on the
property owner, which could result in greater controversy and staff time expended if species are not
properly identified and documented prior to removal and the removal is challenged.
Staff recommends Option A and suggests that the City develop an exempt invasive tree form for the
applicant to fill out, attach a photograph to, and submit for free to the City for verification and permanent
documentation. The form and photograph could be submitted electronically, through the mail, in-person at
City Hall, or during a courtesy call to verify species identification. This process will help to avoid conflicts
regarding the removal of trees that may or may not be listed as species exempt from the tree removal
permit requirements and will also help to ensure replacement of invasive tree species removed from public
ROWS, RP Districts, and previously approved development or mitigation. Rather than issuing a permit, the
City could issue a verification letter.
Other Invasive Species. In addition to the invasive tree species identified in the table, Portuguese laurel
(Prunus (usitanica) is widely accepted as being invasive. However, this species is a densely branched
perennial that is more shrub -like in appearance and is not typically considered a tree. Because Portuguese
laurel is a shrub and looks like a shrub, documenting its removal is probably not necessary. It is reasonable
to simply exempt this species from the tree code altogether, in the same manner as English ivy, poison oak,
and English laurel are currently exempted; the definition of tree found in Chapter 55 could be amended to
include Portuguese laurel as a plant that is not considered a tree for the purposes of the Chapter:
Section 55.02.020 Definitions.
Tree means any woody plant having a trunk 5 caliper inches or larger in diameter at breast height
(DBH). If a tree splits into multiple trunks above ground, but below 4.5 feet, the trunk is measured
at its most narrow point beneath the split, and is considered one tree. If the tree splits into multiple
trunks below ground, each trunk shall be considered one tree. For the purposes of this Chapter,
English laurel, Portuguese laurel, photinia, arborvitae, poison oak, and English ivy shall not be
considered a "tree".
Therefore, rather than exempting Portuguese laurel because of its invasive nature, this species would
simply not be considered a tree and would consequently not be subject to the requirements of LOC
Chapter 55.
Future Tree Code Considerations
In reviewing this proposal with local arborists and the City's Natural Resources Advisory Board (NRAB), staff
received a number of comments relating to a broader scope than invasive tree species per se, which are
summarized below. Staff is not asking Council to deliberate these issues now, but seeks direction on Council
priorities in developing a schedule and process for future tree code considerations.
0 Staff notes the need for a broader public process if LOC Chapter 55 will be evaluated and revised.
Staff should revisit the work of the 2002-2003 Tree Code Task Force as a starting point to
recommending revisions to LOC Chapter 55.
The current diameter threshold for regulated trees is 5 -inches as per LOC Chapter 55. This is the
lowest diameter threshold of any city in the Metro Region. Staff could evaluate the City's minimum
Page 6
diameter threshold for regulated trees.
In LOC Chapter 55, the definition of diameter at breast height (DBH) and the City's standard method
for measuring DBH included in the definition of tree are not consistent with standard arboricultural
and forestry practices. The definitions and methodology are not wrong, but could be improved.
Staff could revise the definition of DBH and the methodology for measuring DBH based on industry
standards.
Some arborists have suggested that the existing tree code should be modified to permit the
removal of trees for hazardous condition when trees are in conflict with infrastructure and when
relocating that infrastructure is not an option. Currently, trees are not permitted for removal solely
because of conflicts with infrastructure. Proper planning prior to development can help to reduce
conflicts with infrastructure, such as planting the right tree in the right place and in some instances,
installing root barriers or other preemptive measures. Techniques like grinding raised sections of
concrete down to grade can be used to resolve some conflicts in the short-term, but long-term fixes
are situational and few and far between. Staff could investigate the implications of permitting the
removal of trees that are causing infrastructure damage.
Certain tree species, which are not known to be invasive and include some native species, are
common nuisances and regularly identified as hazardous in high -use areas. This may be attributed
to inherent species limitations, such as trees that are fast-growing and relatively short-lived with a
tendency to fall apart or fall over with maturity, or other undesirable characteristics. Nevertheless,
these same tree species can have tremendous habitat value if located in open space tracts,
wetlands, or other areas with high environmental value. Staff could explore a streamlined process
for issuing hazardous tree permits in high -use areas for certain tree species that are known to be
common nuisances.
Currently, trees planted as mitigation for tree removal are not inspected. The City does not actively
monitor replanting because of constraints with staff time. Replacement trees help to diversify the
distribution of age classes throughout the City and set the stage for the City's future forest. Proper
planting and maintenance are essential if these trees are to become long-term amenities. Staff
could develop a process for verifying the installation of mitigation trees, but this approach would
require additional budget support.
ALTERNATIVES
Council may direct staff to return with specific implementation actions for the changes proposed here,
including:
1. Code language to exempt the 12 invasive tree species from the City's tree removal permit
requirements and an ordinance for adoption at a future meeting.
2. Code language modifying the definition of tree to include Portuguese laurel as vegetation that is not
considered a "tree" for the purposes of LOC Chapter 55.
3. A manual to aid invasive tree species identification.
4. A process for verifying and documenting species prior to invasive tree removal.
5. A brochure to include with tree removal permits and exempt invasive tree species verification
letters that will provide property owners with information on tree removal, new tree selection,
planting, care and maintenance, and the benefits of trees
Page 7
6. A schedule and process for future tree code improvements.
RECOMMENDATION
The NRAB reviewed a draft of this report and staff presented the recommendations contained herein at the
October 20, 2010 NRAB meeting. Four local arborists attended this meeting and provided comments to the
NRAB. After hearing from staff and the arborists, the Board deliberated the recommendations and voted
unanimously to support the draft staff recommendations to exempt invasive tree species from the City's
tree removal permit requirements, with strong support for a free verification process prior to invasive tree
removal provided by City staff. The NRAB recommended a separate forum to discuss future tree code
considerations and generally encourages Council to include revisions to LOC Chapter 55 as a Council goal.
Staff recommends developing code language to exempt the 12 invasive tree species from the City's tree
removal permit requirements and to modify the definition of tree to include Portuguese laurel as
vegetation that is not considered a "tree". Additionally, staff recommends developing a manual to aid
invasive tree species identification, developing a free City -managed process for verifying and documenting
species prior to invasive tree removal, and developing an informational brochure to include with tree
removal permits and exempt invasive tree species verification letters. Lastly, staff seeks direction on Council
priorities in developing a schedule and process for future tree code improvements.

How Bad Are Invasive Species?
Invasive species impact native plants, animals, and
natural ecosystems by:
• Reducing native biological diversity
■ Altering hydrologic conditions & flooding
regimes
• Altering soil characteristics
• Altering fire intensity and frequency
• Interfering with natural succession
• Competing for native pollinators
■ Repelling or poisoning native insects
• Displacing rare plant species
• Increasing predation on native birds
■ Serving as reservoirs of plant pathogens
• Replacing complex communities with
monocultures
• Diluting the genetic composition of native
species through hybridization

What the heck is an invasive plant?
You say it. nifty, and I say it' noxious.
You say it c lovely, and I say its lousy.
Nifty, noxious, lovely, lou4y -
I_et' call them what they are!
What is a Native Species?
All organisms are native to planet Earth (until further
notice) and each species of bacteria, fungi, plant, ani-
mal, and other creature has a home somewhere on this
planet where it has existed and evolved for thousands
of years. A native or indigenous species is one that oc-
curs in a particular place without the help of humans,
which is not always easy to determine. Species native to
North America are generally recognized as those occur-
ring on the continent prior to European settlement.
An organism's home, or native range, is determined
by a host of influences such as climate, geology, soils,
hydrology, biological interactions, and natural dispersal.
Living things disperse within their native ranges by
moving around on their own or with the help of air,
water, wind, and other animals. However, beginning with
Columbus' discovery of America in the 15th century,
people have played an increasingly significant role in
moving plants, animals and other organisms around the
world, to places for beyond their likely natural dispersal
ranges. And this is where the trouble lies!
What's an Exotic Species?
An organism is considered exotic (alien, foreign, non -
indigenous, non-native) when it has been introduced
by humans to a location(s) outside its native or natural
range. This designation applies to a species introduced
from another continent, another ecosystem, and even
another habitat within an ecosystem.
For example, black locust (Robinia pseudoacacia), a tree
that is native to the southern Appalachian region and
portions of Indiana, Illinois and Missouri, was planted
throughout the U.5. for living fences, erosion control,
and other uses for many years. Black locust is consid-
ered exotic outside its natural native range because it
got to these new places by human introduction rather
than by natural dispersal. Another example is saltmarsh
cordgrass (Spartina alterniflora), a wetland plant that is
native to eastern North American estuaries. Saltmarsh
cordgrass was introduced intentionally to western
North American shoreline habitats, where it did not
occur previously. Sadly, it has become established and
is now considered a serious invasive species, displacing
native species and adversely impacting wetland com-
munities and several endangered native bird and plant
species.
European settlers brought hundreds of plants to North
America from their home lands for use as food and
medicine, and for ornamental, sentimental, and other
purposes. Introductions of exotic plants continue today
and are increasing due to a large and ever-expanding
human population, increased international travel and
trade, and other factors.
Once an Exotic, Always an Exotic!
An estimated 3,500 species of exotic plants have
escaped cultivation in the U.5., are able to reproduce in
the wild, and have become established, or "naturalized".
These plants, however much a part of our current
landscapes and ecosystems, are nonetheless exotic,
since they were moved here by people. For centuries,
horticulturists have imported and disseminated
interesting new exotic plants. Unfortunately, many
of these have become invasive pests that are having
serious impacts to native species and ecosystems.
What Makes an Exotic Species Invasive?
(When is a Guest a Pest?)
Many non-native species exist in apparent harmony in
environments where they were introduced. For example,
a relatively small number of exotic plants (e.g., corn,
wheat, rice, oats) form the basis of our agricultural
industry and pose little to no known threat to our
natural ecosystems. The most important aspect of an
alien plant is how it responds to a new environment. An
invasive species is one that spreads and establishes
over large areas, and persists. Invasiveness may be
characterized and enhanced by robust vegetative
growth, high reproductive rate, abundant seed
production, high seed germination rate, and longevity.
Some native plants exhibit invasive tendencies in
certain situations.
How Many Plants are Invasive?
According to the Plant Conservation Alliance's Alien
Plant Working Group, about 1,050 plant species have
been reported as being invasive in natural areas in the
United States (see list of links). This represents an
astonishing one-third or so of the exotic plant species
established and self -reproducing in the wild. Some
invasive species were planted intentionally for erosion
control, livestock grazing, wildlife habitat enhancement,
and ornamental purposes. Others have escaped from
arboretums, botanical gardens, and our own backyards.
Free from the complex array of natural controls
present in their native lands, including herbivores,
parasites, and diseases, exotic plants may experience
rapid and unrestricted growth in novel environments.

CITY COUNCIL SPECIAL MEETING
MINUTES
NOVEMBER 9, 2010
Mayor Jack D Hoffman called the special City Council meeting to order at 6:34 p.m. on
November 9, 2010, in the City Council Chambers, 380 A Avenue.
Present: Mayor Hoffman, Councilors Hennagin, Olson, Moncrieff, Jordan, Tierney, and
Vizzini.
Staff Present: Alex McIntyre, City Manager; David Donaldson, Assistant City Manager; Larry
Goff, Assistant Fire Chief; Bonnie Hirshberger, Citizen Information Specialist; Denise
Frisbee, Director of Planning and Building Services; Jonna Papaefthimiou, Natural
Resources Planner; Morgan Holen, Assistant Natural Resources Planner; Guy Graham,
Public Works Director
3. STUDY SESSION
3.1 Emergency Operations Plan Update
David Donaldson, Assistant City Manager provided a background of the Emergency Operations
Plan (EOP) via PowerPoint presentation which would be presented for adoption at the December
10, 2010 Council Meeting. He reviewed the City's role and responsibility during an emergency that
included as a first step the City declaring an emergency. The role of the plan was to help the City
organize in the event of an emergency. The plan has 15 Emergency Support Functions (ESF) that
match up with similar functions of the County, State and Federal Government.
Bonnie Hirshberger, Citizen Information Specialist presented an overview of training and
exercise which included National Incident Management System (NIMS) and ICS training. NIMS
provides a nationwide template for terminology, roles and responsibilities in an emergency. A new
computer based program called WebEOC, an emergency management system, has also been
implemented. Training and exercise also included winter storm tabletop and regional functional
exercises as well as elected officials training.
Larry Goff, Assistant Fire Chief presented an overview of the Community Emergency Response
Team (CERT) program and Amateur Radio Emergency Services (LO -ARES), also known as
HAMs.
Ms. Hirshberger stated emergency preparedness began on the local level, specifically in the
home. She presented information on HelloLO, the Emergency Preparedness Forum, the
Emergency Management website and the CERT newsletter.
Mr. Donaldson stated that they had prepared a FEMA compliant hazard mitigation plan and
received $925,000 or $950,000 in grant money which was being used to expand the capacity of
the dam to release water more quickly. This was expected to be completed within the next 45
days. The Lake Corporation partnered on the project. It was expected to reduce flooding both on
the lake and on State Street. He stated the overall goal of the plan was for it to be NIMS compliant
and consistent with the County's plan. They have also developed Continuity of Operations (COOP)
plans with several departments that consider how the departments would operate should the
building be shut down.

November 9, 2010
Councilor Moncrieff had accompanied Mr. Goff to the regional emergency management meetings
and knew first hand that Lake Oswego was prepared. Mr. Goff was available to speak to
neighborhood associations about preparedness.
Mr. Goff responded to Councilor Tierney that the biggest risk to the City successfully responding
to a disaster was the citizens not being prepared. There were typically 13 firefighters on duty at any
one time to cover approximately 50,000 citizens.
Alex McIntyre, City Manager stated his biggest concern was getting the first responders into the
city as most lived outside of Lake Oswego.
Councilor Jordan encouraged everyone to get involved in the CERT training in some way.
Mr. Donaldson responded to Councilor Hennagin that they have considered how to respond to
an occurrence like a 300 year earthquake. Mr. Goff said that they realized that a seismic event
would result in bridge and overpass failures. He confirmed that there were emergency generators
in all the fire facilities. The amateur radio operators were very self sufficient as well.
3.2 Proposed Changes to LOC 50.16 "Sensitive Lands"
Jonna Papaefthimiou, Natural Resource Planner explained that the mural displayed via
PowerPoint had been newly painted on the backside of the Rite-Aid and Starbucks at the Lake
Grove Shopping Center. The project was collaborated between the City, Lake Grove Business
Association and Miller Paints. AmeriCorps Community Forestry Coordinator Nicole Roscos.
Denise Frisbee, Director of Planning stated when they met last July, it was to determine which
Second Look Task Force recommendations the Council wanted to adopt and move forward. The
proposed amendments would clarify to citizens what uses they could make of their own property in
the buffer areas. Next week they would discuss natural area restoration and maintenance and
cross department staff proposals for improving the City's education and outreach efforts around
natural resource protection. The Second Look Task Force noted that having a protection program
is not a choice but is required by Metro's Title 3 and 13 and natural resources are not evenly
distributed around the City. The inventory included approximately 1,800 properties that had some
designation of sensitive lands. There are approximately 11,600 single family residential properties
in the city. Of those, approximately 950 are private properties with sensitive lands designation
which is less than 10 percent of the single family residential properties in the city. In 90 percent of
the properties, the designated resource addresses only a small portion of the property. The
proposed amendments were reviewed by the Planning Commission both in a study session and a
public hearing.
Ms. Frisbee clarified for Councilor Hennagin that they were there to discuss the proposed Code
amendments and the invasive tree update and improvement. She gave an overview of the issues
to be discussed at future Council meetings, noting upland tree groves would be addressed on
November 30.
Ms. Papaefthimiou presented the changes in the Code recommended by the Planning
Commission via PowerPoint. An overview was given of the current exemptions and the proposed
additional exempt uses. One proposed additional exemption was for up to a 700 square foot
addition to an existing primary dwelling when the new intrusion is not closer to the water feature.
Ms. Papaefthimiou explained for Mayor Hoffman that the 700 square foot footprint was a
compromise between the 500 feet and 1000 feet figures suggested.
Ms. Papaefthimiou clarified for Councilor Tierney that they would establish the boundary of the
water feature and determine the shortest distance from the house to that edge and require that the
addition could not reduce that distance.

November 9, 2010
Ms. Papaefthimiou responded to Mayor Hoffman that on November 30 the proposal for the fee
schedule is to eliminate the fee for that application in all cases. The City would delineate it in the
case of a stream and the property owner would do the delineation in the case of a wetland. Often if
the lot is developed, it is already delineated.
Ms. Papaefthimiou indicated to Councilor Jordan that in addition to complying with the sensitive
lands regulations when an addition was done, compliance was also required with the City's rules
related to FEMA. Other complications arise when building in the floodway, but these were
addressed by the Public Works Engineers. Whether additional flood insurance would be required
was a good question.
Ms. Frisbee pointed out that the Metro model code called for a 500 square foot addition and Metro
indicated in a letter they would be more comfortable if the 700 square foot figure were backed
down. Councilor Olson stated it needed to be made clearer that it was the footprint square
footage as opposed to the total square footage.
Ms. Papaefthimiou responded to Councilor Vizzini proposed additions needed to show a
drainage plan and meet the drainage standard as part of their application, but it would not increase
their obligations over the existing house. Ms. Frisbee stated in response to a question from
Councilor Vizzini that she would verify with Storm Water Management in Public Works if doing the
addition would trigger storm water management for the entire building.
Ms. Frisbee responded to Councilor Tierney that when they met with Metro, they wanted to see if
they were going to strengthen their education and outreach and what the overall package would
be. The November 9 letter from Tim O'Brien was attempting to reflect that.
Councilor Tierney appreciated that Staff and the Commission were looking at additional
measures to allow for reasonable impacts into the RC and the RP.
Ms. Papaefthimiou responded to Councilor Olson that the language about the expansion being
no closer to a protected water feature than the existing structure was also in the Metro model code.
She agreed that additions were usually made to the back of structures which could make it
impossible for a lot of people to expand without being closer to a water feature, but others would
be able to expand. If the protected feature was a tree grove or something other than a water
feature, the full 700 square foot expansion could be made.
Ms. Frisbee agreed with Mayor Hoffman that if the property were in a tree grove, there would be
a free pass for an additional 700 square feet. The outer edge of the tree grove is the less
functionally valuable portion of the resource, but development near a water course or stream is
inherently a big problem. They would still have to comply with tree code; requests to build outside
decks comprised 90 percent of the requests. The tree code requires a permit but allows trees to be
cut down for development purposes.
Ms. Frisbee confirmed for Councilor Tierney that the decks counted when measuring distance to
the water feature.
Ms. Papaefthimiou responded to Councilor Moncrieff that for the de minimis development the
City was not more restrictive than Metro. The amendments would make them less restrictive in that
instead of having a 500 -foot addition and 120 square feet of new development, a 700 -foot addition
with 200 square feet of new development would be allowed.
Ms. Papaefthimiou confirmed for Councilor Hennagin they could not do the 700 square foot
addition if they exceed their maximum allowable footprint. There was still lot coverage that applied
on every lot. Ms. Frisbee agreed the lot coverage issue was important along with setback issues
which ended up often being more limiting than the restrictions they were discussing.
Councilor Jordan found it interesting that there could be up to 1,400 square feet additional when
people were talking about wanting smaller homes.
City Council Special Meeting Minutes Page 3 of 13
November 9, 2010
Ms. Frisbee clarified for Councilor Moncrieff that the lot coverage restrictions had nothing to do
with sensitive lands but was the City lot coverage restrictions that applied to every residential
structure.
Ms. Papaefthimiou reviewed the proposed additional exempt uses for de minimis impacts which
included up to 200 square feet of new development as long as the development was not actually in
a wetland or a stream, no grading or filling was done in the riparian area, and the exterior lighting
was low voltage. This would allow for things such as sheds or hot tubs. She confirmed for
Councilor Olson that the Metro model code allowed up to 120 square feet of new development
annually.
Ms. Frisbee stated cumulative structures could cause problems and Metro was supportive of the
City moving to a higher limit as opposed to a lower limit on a cumulative basis.
Councilor Olson struggled with the fact that there was not more flexibility. One was forced to
choose between a garden and a shed for example. Fences also counted into the 200 square feet.
The Metro model code would be better in this case.
Ms. Papaefthimiou responded to Mayor Hoffman that the Planning Commission discussed the
issue of cumulative impacts more in the context of how it would be tracked or enforced. Although
the Metro model code allowed 120 square feet every year, that was not their intent when it was
drafted.
Ms. Papaefthimiou responded to Councilor Hennagin that this did not have the same restriction
as the 700 square feet of addition to a house not going further into a riparian area. This would be
available to all people who own sensitive lands to develop within the riparian buffer.
Ms. Papaefthimiou confirmed for Mayor Hoffman that it could not be below the top of the bank of
a stream or actually in a wetland. If native plants were removed to plant a lawn, the lawn would
count as new development.
Councilor Olson attended the Planning Commission public hearing on this issue. It was pointed
out that 200 square feet was a reasonable number for an average city lot but for larger areas, it
was minimal.
Ms. Papaefthimiou agreed with the suggestion of Councilor Jordan that a provision could be
made that larger lots would have a larger potential impact area.
Councilor Vizzini was disturbed that there could be a serial depletion of resources. It was a
loophole one could drive a truck through. He suggested something be crafted that was sensitive to
the size of the property and the size of the resource as opposed to a single amount.
Councilor Moncrieff stated Staff was being given an almost impossible task by being asked to
provide the landowners with certainty while also asking them for flexibility as well as a simplified
Code with less exemptions and variances which was also reasonable.
Councilor Vizzini suggested going to percentages as opposed to absolute square footage. If 200
square feet makes sense for the standard Lake Oswego lot of 7,500 or 10,000 square feet, that
should become a benchmark for sizing up. The question should not be the percentage of the total
lot but the percentage of the resource area that would be intruded upon.
Ms. Frisbee responded to Councilor Tierney they were trying to set up bright lines for people so
they did not need to go through processes. Discretionary reviews were staff intensive processes.
They would revisit the data summary to get a sense of lot sizes, start with 120 square feet and then
adjust it accordingly with a maximum at some level.
Ms. Papaefthimiou confirmed for Councilor Tierney that fences would be included in the square
footage.
City Council Special Meeting Minutes Page 4 of 13
November 9, 2010
Ms. Papaefthimiou confirmed for Councilor Hennagin that if someone had 20,000 square foot lot
with 500 square feet of a tree grove, even though they may have plenty of area to build an
improvement, they would still get to go 200 feet into the tree grove.
Councilor Olson stated the Code changes were meant to provide more flexibility and make things
less complex but they did not. To solve some of the complexity, she suggested removing tree
groves from private backyards.
Councilor Moncrieff noted that on July 20, Council passed Resolution 10-51A that directed Staff
to come back with these specific Code changes and this is exactly what Staff has brought back.
Ms. Papaefthimiou responded to Councilor Jordan that the uses they were looking at were just
exceptions, which do not require any type of application. If someone wanted to do a project more
than 200 square feet, under the current proposal it would not qualify as an exception, but they
could still make an application to do that development and work with Staff to find the best way that
it might fit. They could also apply for a buffer reduction. These would be application processes
where they would have to do the paperwork and pay the fee. It would not be just an exemption.
Mayor Hoffman reminded they were asking Council to confirm what they and the Planning
Commission have produced was responsive to what Council asked Staff to do in July and he
believed it was.
Councilor Hennagin preferred to see some kind of proportional plan based on zones.
Mayor Hoffman stated the challenge was that it was not the zone but that a 50,000 square foot lot
could be in an R7 zone.
Councilor Hennagin was more concerned about making it proportional so that larger lots would
have an exception that was larger than 200 square feet.
Ms. Papaefthimiou responded to Councilor Vizzini that they had considered setting a maximum
that is a percentage of the resource area on the property. The problem with doing it as a de
minimis exception was that if your development was a percentage of the total resource area, you
would have to figure out what the total resource area is which often means walking the property,
making a survey and producing maps and becomes cumbersome for those wanting just to buy a
garden shed to place on the property.
Ms. Papaefthimiou stated the footprint of a fence was very skinny and would not significantly
impact the 200 square feet of allowable development. Ms. Frisbee explained that there was a
permit requirement for fences over a certain height. The City wanted to extend that so fences are
allowed even in a resource area with no special permitting required, essentially fences would be
exempt. Ms. Papaefthimiou agreed with Councilor Vizzini that the language could be adjusted to
read up to 200 square feet plus fences.
Ms. Papaefthimiou confirmed for Councilor Tierney that the language regarded sturdy,
recognizable, fences that could keep a dog in or out of a yard, for example, not necessarily habitat
friendly fences.
Ms. Papaefthimiou summarized the discussed change stating that in the resource buffer, which is
to say in tree groves and in the 25 or 30 feet from the top of bank of streams, any fence was
allowed that met the Fence Code. Additionally, recognizing that often a stream runs along a
property line and owners might want to fence that area also, even below the top of bank of stream
or in a wetland if that is the edge of their property, those fences were also specifically allowed.
They tried to simplify the standard as much as possible without totally getting rid of the provision to
protect wildlife, so it had to have one escape path for wildlife, such as a smaller 2 -foot segment of
the fence to prevent wildlife from becoming trapped in a backyard area.
Ms. Frisbee stated the reality was that people did not come in to put a fence across their wetland
or below the top of the bank. People have expressed a desire to put a fence in their backyard
without having to worry about exactly where the resource buffer is and without having to delineate.
City Council Special Meeting Minutes Page 5 of 13
November 9, 2010
This effort was in response to that need. People wanted to keep their cats and dogs in the yard
without worrying about putting in the escape hatch or the 6 -inch escape way. In response to the
concern raised about someone possibly putting a fence across a wetland or below the top of a
bank, they included the provision that the wildlife friendly requirement would then need addressed.
Ms. Frisbee responded to Councilor Vizzini that they did not want to put people through the effort
of delineating in order to see exactly how far the resource extended. Along with easing the
restrictions, they were following up with better education about best practices by talking to those
wanting to build fences.
Ms. Papaefthimiou agreed with Councilor Vizzini that the goal was to come up with a way to put
a fence in a backyard in a way that still allowed for the migration of animals across the landscape.
Education and outreach programs would help with those goals.
Ms. Papaefthimiou affirmed for Councilor Jordan that one could fence their tree grove and the
issue was whether or not people could build fences in streams or wetlands.
Councilor Tierney was not supportive of number 4, page 7 of the Staff report that allowed fences
in wetlands and the RPs. The letter from Gary Buford concurred with his opinion.
Councilor Olson added they needed to be careful as it also allowed a fence below the top of bank
of a stream. Some people have a stream and then there is a very gradual slope up of maybe 100
feet. This would allow them to put a fence somewhere between the top and the stream.
Councilor Tierney noted that would get to the question of how the top of bank was defined.
Ms. Papaefthimiou proposed Staff return with language that does not rely on the top of bank but
simply says that fences are allowed except across or below the ordinary high water mark, for
example.
Councilor Olson questioned how to deal with a property owner with a ditch that was dry three-
quarters of the year and one foot beyond their property line where they wanted to put a fence.
Mayor Hoffman believed there was enough agreement to move forward.
Councilor Olson stated that somehow they had skipped over a lot of number 3. They discussed
the 200 square feet but not the grading permit or lighting.
Ms. Papaefthimiou responded to Councilor Olson that in regard to issues of grading, a property
owner who wanted to put in a shed and level the ground would not need a grading permit. The
grading permit was issued by the Building Department, and she believed it would involve about 10
cubic yards of fill. At that point, they would already have to go through an application process to
comply with the Building Department's requirements, so also doing an application through the
Planning Department at that time would not be burdensome. It did not mean it would not be
allowed, but rather it would not be exempt. Low voltage landscape lighting includes lights that
dissipate at about 8 feet in distance from the light source. The intent was that it would still be
sufficient to light a pathway, house numbers, driveways and the like. A road or house going
through the application process could be approved for brighter lights such as street lights or
exterior lighting to the house.
Councilor Moncrieff stated that in the neighborhood planning process, people were lobbying
strongly for lower lights without glare that did not spill over into other neighbor's property lines.
Councilor Olson stated anyone could get any kind of lights they wanted unless they had a tree
grove in their backyard that was designated sensitive land.
Councilor Moncrieff noted that the issue came up with the high school football games as well.
Light spillover always came up.
Councilor Olson clarified that spillover was not the issue. They were discussing low voltage lights
that had limited range which was different.
City Council Special Meeting Minutes Page 6 of 13
November 9, 2010
Councilor Hennagin wondered if the terminology was appropriate. Halogen lights with low voltage
could emit huge amounts of light. Wattage would be a more appropriate term. If yard lighting was
to be restricted, it should be restricted in all outdoor yards not just yards in a resource protected
area.
Ms. Papaefthimiou confirmed for Councilor Jordan this was the type of lighting that could be
used within the resource. Other lighting was allowed outside of the resource. If a house was
already built within a resource, security lights were not prohibited, because those lights would be
accessory to the structure, which would be a legal permitted dwelling. The proposal was for a new
development in the resource area that was free standing.
Councilor Olson noted there were already other restrictions on lighting on houses in the Code.
There were prohibitions against security lights in the sensitive lands code already. Ms. Frisbee
stated this was intended to allow more flexibility by allowing a certain type of lighting in the
resource area. The issue was if enough lighting was allowed.
Ms. Papaefthimiou responded to Councilor Tierney that she did not believe there would be a
restriction in the lighting allowed if a shed was put in a backyard outside an RP or an RC.
Councilor Tierney concurred with Councilors Olson and Hennagin that the lighting restrictions in
that section was not important and critical and proposed they be deleted.
Mayor Hoffman stated the direction from Council was that the City would allow lighting in the RP
and RC zone. Ms. Frisbee understood that Council did not want lighting to be limited or prohibited
as a use in the resource area in any way other than what the Code currently allows for other non
resource properties. Ms. Papaefthimiou confirmed it would just say not within wetland or stream,
no grading for fill and that was it. Subsection III would be stricken.
Councilor Tierney stated that he worked for PGE and could be the beneficiary of the utility
provision so he recused himself and stepped down from the dais.
Ms. Papaefthimiou presented the proposed exemptions from review of utility work under the
sensitive lands Ordinance. The proposal was to exempt the repair and replacement of existing
lines in utility corridors or developed right-of-ways and to require new lines to come in and be
reviewed, which is to say they would still probably be permitted, but they would have to go through
the application process. The Public Works Department would prefer that new utilities also be
exempt from review under the sensitive lands code as long as they commit to restoring the area
that was impacted by utility construction. Public Works Director, Guy Graham and Metro supported
the recommendation. The Public Works memo was on page 47 of the packet.
David Powell, City Attorney stated proposed language was on pages 48 and 49, and in addition
to suggesting this would apply to new utility development, it also changed the criteria. D1 stated,
"The disturbed portion of the resource district is restored according to City Code," whereas page 7
of the Planning Commission recommendation simply said, "The disturbed portion of the resource
district is restored." If Council wanted to go with something like the language recommended by
Public Works, he suggested having Staff bring back a refinement about what was meant by "City
Code". Many different restoration and mitigation provisions were in Chapter 50.16 that could apply
there.
Ms. Frisbee confirmed for Mayor Hoffman that this was not part of Council's original charge to
Staff but it seemed like a opportune time to discuss utilities in resource areas. Mayor Hoffman
suggested that Public Works, Metro and the City Attorney could determine what was appropriate.
Councilor Vizzini stated the only difference in the language of the Public Works memo regarded
new utility lines; repair and replacement of existing was in both.
Mr. Powell stated it was still in the public right-of-way or in the existing easement; no new
easements were being created.
City Council Special Meeting Minutes Page 7 of 13
November 9, 2010
Councilor Olson believed it was worth Council's time to explore the issue. The Planning
Commission thrashed this issue around for a long time. Before the next meeting, it might be helpful
for Council to get those Planning Commission minutes. She found the last paragraph of the first
page of the November 9, 2010 letter from Tim O'Brien's memo very helpful. Metro believed the
Planning Commission recommendation was consistent with Title 13 and they agreed with it, which
was good enough for her.
Guy Graham, Public Works Director confirmed for Mayor Hoffman that they asked that this be
expanded for new projects because Public Works likes to have all public utilities in the public right-
of-way wherever possible. Because of topography and other things, it often made sense to put
them in areas that were outside the public right-of-way to facilitate the use of gravity for pump
systems, etc. If there was an opportunity to put it in an area that might be environmentally
sensitive, they would want to restore it and take opportunities to actually enhance the area where
those utility lines would go. It would be a de minimis impact but might also improve the area where
possible.
Ms. Papaefthimiou clarified these were de minimis exceptions. Obviously, the City could still
put utilities in resource areas at this time, and often did, but Public Works had to apply to the
Planning Department and move through the typical process. True, Planning did not usually reject
Public Works applications to build essential utilities, so this would take them out of that
process. She confirmed for Councilor Jordan that it could be a new utility line project, but it still
had to be in an existing easement.
Councilor Olson noted it was only talking about new projects such as the water project.
Ms. Papaefthimiou clarified that it was not condemning land and creating new easements.
Councilor Olson stated they could be creating new easements with the water project.
Councilor Jordan pointed out they would need to go through a process.
Ms. Papaefthimiou confirmed for Councilor Hennagin that any utility new line, improvement or
repair that was in an existing easement or an existing right-of-way was considered to be de minimis
as long as the impacted area was restored afterwards. As written that applied to all utilities, not just
public utilities.
Mayor Hoffman called for a ten minute break at 8:30 p.m.
Mayor Hoffman moved to table the utility line discussion and have it brought back after
Staff talked amongst themselves. Councilor Jordan seconded.
Councilor Hennagin asked why Council could not accept the Planning Commission
recommendation.
The motion passed with Mayor Hoffman, Councilors, Olson, Moncrieff, Jordan, and Vizzini
voting 'aye'. Councilor Hennagin voted 'no' [5-1]. [No voice vote taken; more consensus in
nature]
Ms. Papaefthimiou stated the Second Look Task Force and the Planning Commission agreed that
the Department of State Land definition of "ditch" would be useful for the City to incorporate into its
Code. The definition basically said if it was manmade, then it was a ditch.
Ms. Papaefthimiou responded to Councilor Tierney that there were two definitions of ditches, the
simple definition was if it is manmade, it is a ditch, and if it is a creek, then it is not a ditch. Most
ditches are not jurisdictional and therefore not regulated in the City of Lake Oswego. However, at
least one manmade ditch, the Oswego Canal, was regulated, but a portion of it was considered
sensitive lands. In addition to adding the simple definition of ditch to the City Code, Staff proposed
incorporating a reference to the Department of State Land's definition of non -jurisdictional ditches
which are ditches that do not have habitat value. She did not believe that any of those were
currently covered by the Sensitive Lands Ordinance nor should they ever be added in the future.
As the definition shows, ditches basically do not accomplish the purposes of the Sensitive Lands
City Council Special Meeting Minutes Page 8 of 13
November 9, 2010
Ordinance. They do not contribute much to water quality or provide wildlife habitat. The intention
was that non -jurisdictional ditches would never be placed in the RP district and to Staff's
knowledge there were no non -jurisdictional ditches in the RP district currently.
Mr. Powell stated he did not like the language either. On page 15 below the box, the existing Code
said, "the following resources may be placed within the RP district," so that was apparently the type
of verbiage used in that section of the Code. An RP district defines resource protection for water
based resources. He noted if the whole Code were being changed, they were placing the district
over the resource rather than placing the resource in the district. Ms. Papaefthimiou agreed.
Mayor Hoffman summarized that Councilor Tierney was suggesting that the language on page 15
be changed or made clear so that the ditches matched the stream corridors.
Councilor Vizzini agreed with Mr. Powell.
Ms. Papaefthimiou responded to Councilor Olson she did not have the Code in front of her to
check if there was a definition for the term "environmentally significant" as written in Section
50.16.020. It could be inferred that resources that have a qualifying habitat score were significant,
which was but it was not defined there.
Mr. Powell stated that first statement was almost more of a purpose statement. It talked about
protecting the environmentally significant stream corridors and wetlands, and then, before that
language was added, it stated, "which were placed." This was the original structure of the Code. It
also talked about the HAS ranking, which qualifies them to come in.
Councilor Olson noted this was an example of making the Code more complex instead of simpler.
Councilor Hennagin was willing to accept the ditch definition as the widely accepted terminology.
Ms. Papaefthimiou stated the definition was useful because it was exactly copied from the
Department of State Lands. If the City could not figure out whether or not something was a ditch,
they could ask them.
Ms. Papaefthimiou indicated to Mayor Hoffman that Lake Oswego had other ditches besides the
canal, but she was not aware of any others that were considered sensitive lands.
Ms. Frisbee responded to Councilor Hennagin that in the scenario of a landowner digging a
channel to direct runoff into a stream, although it could be significant in terms of water quality and
erosion, it was not regulated by the sensitive lands code unless it had already been identified as an
environmentally significant resource.
Mayor Hoffman asked if there was agreement among a majority of the Council that this was
acceptable and responsive to Council's resolution back in July. Commission Olson was not sure.
Ms. Papaefthimiou continued that the terms RP District, District Buffer and Construction Setback
were used frequently in the Code, but were not that useful. The major problem was that they result
in a setback on a buffer on a district. The proposal was to call a resource what it is, for example, a
stream or a wetland, then the protected area would be adjacent to it, and both the resource and
area together would be referred to as the RP District, which is one unit. The RP District would only
have a construction setback to protect the RP District when things were constructed. That setback
would go away when the construction was done. No additional restrictions would apply.
Ms. Papaefthimiou clarified for Councilor Olson that tree groves did not have a buffer, but a
construction setback. For water resources that were just on one property and the protected riparian
area was on the adjacent property. The intent was if the resource or the RP District is on the
property, it must be mapped on that property. In cases where it was not mapped on that property,
the City needed to correct the map or not regulate on that property. The City was committed to the
map published that people were notified about. The Council would be talking about maps in the
future so the topic of mapping buffer -only properties could be discussed. In reference to the last
paragraph on Page 8 of Council packet, she clarified that Class 2 Water Resources have a 25 -foot
City Council Special Meeting Minutes Page 9 of 13
November 9, 2010
buffer and Class 1 Water Resources have a 30 -foot buffer, which was spelled out clearly in the
Code.
Ms. Papaefthimiou concluded the review of changes by noting the deletion of Prohibitions on
Pesticide and Herbicide Use, which was not a land use matter, and the housekeeping changes of
renumbering.
Ms. Frisbee responded to Councilor Olson that the construction setback buffer was still in, but it
was clarified as temporary and associated just with a construction process so it went away once
construction was completed. It had been confusing before.
Ms. Papaefthimiou responded to Councilor Jordan that there was a definition of stream, but she
was not sure if there was a definition of perennial stream. Mr. Powell stated that under "stream,
perennial," the Code stated, "a stream or part of a stream that flows continuously above ground
during years of average or near average rainfall as a result of groundwater discharge or surface
runoff."
Ms. Frisbee reviewed and clarified the changes agreed on by Council regarding the five new
exceptions as listed in the packet starting on page 6. Staff needed to clarify that Item 1 regarding
routine maintenance and repair, and Item 2 regarding the alteration, expansion or replacement of
an existing primary dwelling unit, are permitted. Mayor Hoffman clarified that the Code did say
"footprint" on the bottom of page 12, so Councilor Olson's prior concern was addressed.
For Item 3, Council asked Staff to return with an explanation of the review process if someone
wanted to do an exempt structure that was more than 200 square feet. The lighting was eliminated,
but Council wanted Staff to reaffirm they were being consistent about lighting between resource
areas and non -resource areas. Ms. Papaefthimiou clarified the definition of the top of stream did
not fit under the de minimis exemptions. Planning Staff was aware that they needed to come up
with a more clear and objective definition. She replied to Mayor Hoffman that top of bank was in
the Code as a graphic definition, but was defined with a picture.
Ms. Frisbee continued with Item 4, stating that fences were exempt and allowed except they
should not be in the wetland or creek and Mr. Powell would help with language to address the wet
feet. Ms. Frisbee confirmed for Councilor Olson that Staff needed to address the ordinary high
water mark. Ms. Papaefthimiou stated the ordinary high water mark was talking about fences, and
that was resolved by saying that the fences should not go across the water at the high or low point.
Councilor Olson stated that on some properties it was astounding how limiting that was.
Ms. Frisbee concluded that Item 5 Utility Line Exemption was tabled, and that the definitions were
as proposed.
Mayor Hoffman confirmed that Staff would return with an ordinance to be adopted at the public
hearing scheduled for December 13.
Councilor Olson commented it was okay as far as it went, but she did not think it went far enough
3.3 Invasive Tree Species to Exempt from Tree Removal Requirements
Morgan Holen, Assistant Natural Resources Planner presented the Staff report regarding the
twelve invasive tree species recommended for exemption from the City's tree removal permit
requirements. She had presented a draft of the Staff report at the Natural Resources Advisory
Board (NRAB) meeting on October 20 and NRAB intended to make a motion supporting the
recommendations at the November 17 meeting. The public hearing is scheduled for December 13.
Ms. Holen responded to Councilor Moncrieff that it was assumed that the City's standard
mitigation size of 2 -inch caliper for deciduous trees and 6 -feet tall for evergreens would be used for
tree replacement, but flexibility could be added. She supported planting bare root seedlings,
especially in natural areas because they adapt better.
City Council Special Meeting Minutes Page 10 of 13
November 9, 2010
Ms. Holen explained to Councilor Tierney that leaving the invasive tree or taking it out and
leaving the ground bare were both detrimental in different ways. If the goal was to encourage the
removal of the invasive trees, she agreed a more flexible mitigation might be appropriate to provide
incentive. She did not have data to verify the number and location of these trees, but the State of
the Urban Forest Report, which was included in the packet, discussed the percentage of certain
trees. For example, many Norway Maples were located in City right-of-ways, and right-of-way
replacement is always required so this regarded those next to streams.
Ms. Frisbee clarified for Mayor Hoffman that these were not requirements to remove trees. If a
tree was removed in a right-of-way, a replacement tree was required.
Councilor Vizzini stated it was almost as if they were taking away a regulatory burden of having to
get a permit to remove a tree on one hand and then adding a regulatory requirement of having to
plant on the other hand. He would like to see a solution that made it easy for people to get trees in
the ground. He suggested the City partner with local nurseries to provide bare root stock at a
discount by buying in volume, or use a portion of Luscher Farm to grow nursery stock to be made
available to property owners trying to replace trees. Portland's Leave Edge Program uses sewer
right-of-way to grow nursery stock for the City of Portland's re -vegetation program. Ms. Frisbee
clarified that they were just suggesting that replacement be required in certain areas. Education
and outreach would be an important aspect of the plan. Having the City Arborist consult with
property owners about replanting streamside and providing education materials and perhaps
discounts to local nurseries would all be meaningful.
Mayor Hoffman agreed that requiring tree replacement could discourage people from removing
invasive trees.
Councilor Vizzini said the replacement requirement would hinder the removal of invasive trees in
certain areas. He was particularly concerned about loss of soils, erosion and the storm water
management impacts of losing trees in the described areas.
Ms. Holen responded that Staff would discuss the concerns raised and come up with possible
solutions. She noted a big question was whether it was solely the property owner's responsibility to
verify and document an invasive tree species, or should the City have a process for verifying and
documenting that the tree is indeed an invasive species. Rather than issuing a permit, perhaps a
free verification letter to avoid disputes or conflicts, especially between neighbors. Staff
recommended that the City develop an exempt invasive tree form for applicants to fill out with
certain attached photographs and send to the City. Staff could also make courtesy call to see the
tree and the materials could be given to Staff. The documentation would be kept on file. The
property owner would receive a verification letter from the City with information about planting the
right tree in the right spot, and about tree removal, stump sprouting, etc.
Councilor Tierney reiterated that the goal was to easily allow invasive species to be removed, and
now the process was not much different than the process to obtain a tree cutting permit. Adding
additional steps decreases one's motivation. Currently, code enforcement was based upon
complaints and he believed that would satisfy this situation as well.
Mayor Hoffman suggested the easiest thing might be to have a purple ribbon tied around trees
that someone identified as invasive for the City or a City contractor to come out and verify. Such a
process could not be that complicated. Upon inspection, the City would confirm that the tree was
invasive and that the property owner must replace the tree.
Councilor Moncrieff interpreted that a permit was not needed to cut down an invasive tree, but if
there was a concern that Code Enforcement could be called, a photo might want to be taken of the
tree to prove the tree was invasive. If there was a question about the species, the City could be
called to verify.
Ms. Holen stated she wanted to keep it as simple as possible but knew how contentious trees
could be in the city and sought guidance from Council. She suggested implementing the program
for a while without a verification process to see if there were problems and possibly adjust it later.

Mayor Hoffman wanted the City to make a decision on the tree prior to removal.
Ms. Holen stated she tried to make it easy on people by providing an online form to which digital
pictures could be attached and submitted. The planners could then review the information and
send the verification letter right back.
Councilor Vizzini stated professional tree removal companies could verify tree species. If trees
were small enough to be removed by individuals, most would be smaller than the minimum size for
a tree permit. Educating the professional community would help insure that trees were not being
removed that required a permit. He agreed the process needed to be as painless as possible.
There needed to be a way to insure that something was replanted in the required areas, and that
reporting needed to be simplified as well.
Ms. Holen responded to Councilor Hennagin that alder was not on the list because it was native.
Invasive species were defined as being non-native, not those that overtake other vegetation.
Councilor Jordan noted that whether or not the trees were invasive, it would take a while to
replant and grow trees to replace the tree canopy. Having a property owner remove three large
Norway Maples would change the feel of the neighborhood and spark neighborhood complaints.
Tree size was an issue because invasive or not, larger trees provide shade and privacy.
Mayor Hoffman noted that proposed changes 1 through 5 on page 56 of the Council packet
respond to Resolution 10-51A. Ms. Frisbee clarified that number 6 was just something on their
radar screen at some point.
Councilor Olson stated in reference to number 6 that she had replaced her sidewalk about three
times because of six giant sweetgum trees. They were beautiful but very destructive of
infrastructure. She encouraged the pursuit of permitting the removal of trees in right-of-ways
causing infrastructure damage.
Ms. Holen responded to Councilor Tierney and Mayor Hoffman that work on the tree removal
process and mitigation would continue and more alternatives provided. She agreed to return before
December 13 for a check in on that issue. The goal was to make the process easier and simpler
without substituting one regulation for the other.
Councilor Olson liked the suggestion of having a trial period for a very simple process without a
required permit and trust people to mitigate. Ms. Holen confirmed that the photographic manual
would be online as well.
Councilor Jordan added that working with local nurseries to educate the public and help them
identify invasive species would be helpful as well.
Councilor Vizzini reiterated that working with the local tree professionals to insure they were
aware of the change in policy would be worth the effort.
Councilor Tierney stated that because they were going to be considering the fee schedule on
November 30, he wanted to continue the discussion about the capital expenditures. He asked that
Staff be prepared to discuss two issues. One was if the City did not have the capacity to spend the
annual street maintenance, including water and sewer, that the street maintenance fee be adjusted
appropriately so there was an alignment of what the City had the capacity to do. He wanted to look
back a few years to review what was spent last year, projected for this year, and ensure that the
revenues from doubling rates over a three-year period matched up. The second matter regarded
whether a consistent plan existed, if projects needed this funding; presently there was an
inconsistency.
Robyn Christie, City Recorder distributed and discussed with Council the proposed new tentative
meeting schedule and reviewed possible adjustments to accommodate various agenda items.
Councilor Olson suggested having all City Council meetings televised.
