RIVER TERRACE COMMUNITY PLAN
Introduction and Background
River Terrace is located within the City of Tigard and inside the Portland Metropolitan Urban Growth
Boundary(UGB) on its westernmost edge. See Figures 1-1 and 1-2 for reference. It consists of
approximately 490 acres that is currently in agricultural use with some single family residences. It is
bounded by unincorporated Washington County
residential development to the east and rural Figure 1-1: River Terrace Location
agricultural land to the north,west and south.
Most of the agricultural land to the west and
south of River Terrace is designated Urban 217
Reserve Area on the Metro 2040 Growth
Concept Map.The agricultural land to the
north of River Terrace,known as South
Cooper Mountain,is inside the UGB within
Y
the City of Beaverton. Similar to River 7,�
Terrace,long range planning efforts are
underway in South Cooper Mountain to r
facilitate its transition from rural to urban land
use.
The River Terrace Community Plan,hereafter
referred to as the Community Plan,is a long
range planning document that supplements
the Tigard Comprehensive Plan. River Terrace Plan Area —Tigard City Boundary
Figure 1-2:Urban Growth Boundary It is designed to guide development and investment in
River Terrace over the next several decades as it
transitions from rural to urban land use to accommodate

■ Goal 5 Natural Resources
■ Goal 8 Recreational Needs
■ Goal 10 Housing

RIVER TERRACE COMMUNITY PLAN
■ Goal 11 Public Facilities and Services
■ Goal 12 Transportation
• Goal 14 Urbanization
In addition to the Community Plan, five infrastructure master plans were created during the community
planning process to provide for the timely,orderly and efficient provision of public facilities and
services in River Terrace.All five master plans are independent of the Community Plan but collectively
serve as its foundation.They were developed to support the proposed land uses and zoning district
designations,which are described in more detail in the section on Land Use.They identify the major
facilities and capacity improvements that will be needed to support full build-out of the area and include
planning level cost estimates for all identified public facility projects.A summary of each of these master
plans can be found in the sections on Parks,Public Facilities and Transportation.
A funding strategy was also developed concurrently with the Community Plan pursuant to state and
regional requirements. It utilized the project lists and cost estimates identified in the five master plans
described above.The purpose of the River Terrace Funding Strategy is to provide a viable near-and
long-term funding strategy for all infrastructure improvements identified in the River Terrace master
plans.
The following topics are addressed in this section.
• Community Plan Development
■ Community Plan Adoption
• Community Plan Implementation

Community Plan Development
Area 64
Community Plan Area History
Most of the land in River Terrace,approximately 440
acres,was added to the UGB in 2002,at which time it
was identified as Areas 63 and 64.Washington County
completed the concept plan for Areas 63 and 64 in I '
2010.This plan,entitled the West Bull Mountain _,�
Concept Plan(WBMCP),included Areas 63 and 64 [ �1
and a rural subarea to the south of both areas that
extended to Beef Bend Road.This rural subarea was ROY
included in the concept planning process to facilitate vests ~
logical street connections and urban service extensions Area 63
since Areas 63 and 64 were not contiguous to one I
another.
Approximately 50 acres of this rural subarea was
added to the UGB in 2011,at which time it was
identified as Roy Rogers West. Collectively these three
areas,i.e.Area 63,Area 64 and Roy Rogers West,
comprise the River Terrace planning area. Unlike the WBMCP,the River Terrace Community Plan does
not include the remainder of the rural subarea (which is now an Urban Reserve Area) to the south of
River Terrace.The entire 490-acre area that makes up River Terrace was annexed to the city in two
batches.The first annexation petition was approved in 2011.The second was approved in 2013.

City
In 2012,Washington County and the City of Tigard entered into an intergovernmental agreement(IGA)
whereby the county assigned and the city agreed to accept responsibility for preparing a community plan
based on the concept planning efforts completed by the county in 2010 for the area now known as
River Terrace (and formerly known as West Bull Mountain). Pursuant to the IGA and in furtherance of
Metro Functional Plan Titles 11 and 14,the city agreed to"refine the County's West Bull Mountain
Concept Plan and provide a detailed land use,public infrastructure,governance,and financial planning
framework for urban development of the concept planned area." In tum,the county agreed to support
the city's efforts to complete the River Terrace Community Plan.
Community Plan Refinements
Below is a summary of key plan refinements that were made during the River Terrace community
planning process.This summary documents the major differences between the WBMCP and the River
Terrace Community Plan.
Land Use
■ The recommended land use and zoning district designations are based upon the adopted
WBMCP land uses.Minor refinements were made during the community planning process to
support a better range and mix of zoning districts and,by extension,housing types.
■ The commercial area was shifted to the west to improve its visibility from Roy Rogers Road. Its
overall size was not increased.
Parks
■ Specific park sites were not identified in the River Terrace Park System Master Plan Addendum
consistent with city land acquisition policies.
■ The park and trail demand in River Terrace was calculated using the city's current level of
service (LOS) standard instead of the hybrid LOS standard developed during the WBMCP
process.
Stormwater
■ The southern stormwater management strategy was adjusted to reflect the current UGB. Instead
of utilizing the flat area along the northern edge of Beef Bend Road for detention,which is not
inside the UGB at this time,the River Terrace Stormwater Master Plan recommends conveying
City of Tigard Page 1-3
RIVER TERRACE COMMUNITY PLAN
this runoff all the way to the Tualatin River via a single off-site improvement in the form of a
high-flow bypass pipe or a combination of pipe and stream restoration.
■ The sizes of the stormwater detention facilities were adjusted to reflect the city's intention to
utilize a continuous simulation hydrologic model. This model is being developed in partnership
with Clean Water Services.
Transportation
■ The southern road network was adjusted to reflect the current UGB. Instead of two north-south
Neighborhood Routes,the River Terrace Transportation System Plan (TSP) Addendum only
envisions one north-south connection to Beef Bend Road along an existing private road
alignment.This alignment is also the location of the recommended high-flow stormwater
conveyance improvements described above.
■ The main north-south street parallel and to the east of Roy Rogers Road was changed from a
Neighborhood Route to a Collector Street to reflect anticipated traffic volumes and to be
consistent with other collector streets in the city.This street is identified as River Terrace
Boulevard in the River Terrace TSP Addendum.
■ No additional intersections were added to existing Washington County facilities,i.e. Roy Rogers
Road or Scholls Ferry Road,but a traffic signal was added at the future Scholls Ferry
Road/River Terrace Blvd intersection to safely accommodate all modes of travel and to
minimize traffic impacts on existing adjacent neighborhoods.
■ All local street connections to existing Bull Mountain neighborhoods were kept in the
Community Plan,with the exception of the one at Leeding Lane.This connection was
downgraded from a vehicle connection to a pedestrian and bicycle connection to lessen the
transportation impacts on an existing wetland.
■ The greenway trail along Roy Rogers Road and Scholls Ferry Road was eliminated for a number
of reasons.The main one being that most stakeholders preferred the location of the River
Terrace Trail and felt that the inclusion of both was neither feasible nor necessary given the
proximity of both trails to each other.
Regulatory Framework
Metro Functional Plan Titles 11 and 14 figure prominently in the community planning process and are
heavily referenced throughout the Community Plan.Title 11 (and corresponding Statewide Planning
Goal 11) calls for long-range planning to ensure that areas brought into the UGB are urbanized
efficiently and become or contribute to mixed-use,walkable, transit-friendly communities. Statewide
Planning Goal 11 also has specific requirements related to the development of a Public Facilities Plan to
ensure the timely,orderly and efficient provision of public facilities and services in urbanizing areas.
Title 14 (and corresponding Statewide Planning Goal 14) calls for a clear transition from rural to urban
development,an adequate supply of urban land to accommodate long-term population and
employment,and a compact urban form.
Page 1-4 City of Tigard
RIVER TERRACE COMMUNITY PLAN
The city is required to prepare and adopt comprehensive plan provisions,public facility plans and land
use regulations to meet the requirements of the specific Metro ordinances that added River Terrace to
the UGB,namely Ordinances 02-969B and 11-1264B,as well as Metro Functional Plan Titles 11 and 14
and Statewide Planning Goals 11 and 14.The city is also required to maintain and periodically update its
Comprehensive Plan. It recently completed a major plan
update in 2008,but this update preceded the city's agreement

land use and public facility planning.
The completion and adoption of the River Terrace Community
Plan,River Terrace Funding Strategy and various River Terrace
infrastructure master plans collectively meet all city,state and Metro requirements for land use and
public facility planning. In combination,these documents provide for the orderly and efficient transition
of River Terrace from rural to urban land use and contribute to meeting the city's Public Facilities Plan
requirement under Statewide Planning Goal 11.
Community Plan Adoption
The River Terrace community planning process has resulted in the creation of a number of documents
that fall into one of three categories: Infrastructure Master Plans,River Terrace Community Plan and
Maps,and Implementation Documents.
Infrastructure Master Plans
Of the five infrastructure master plans that were developed for River Terrace,the master plans for
water,sewer and stormwater have already been adopted.The master plans for parks and transportation
are expected to be adopted with the Community Plan.
River Terrace Community Plan and Maps
The River Terrace Community Plan includes 14 maps.They are provided for informational purposes
only.The majority of them,Maps 6— 14,exist in a more technical form in one of the five infrastructure
master plans described above.These maps are adopted when their respective master plans are adopted.
Maps 1 —5 are standalone maps.Three show inventoried natural resources in River Terrace.The other
two show Comprehensive Plan and Zoning District designations.A separate action is required to adopt
these maps,as adoption of the Community Plan does not result in their adoption. Once zoning districts
have been adopted and are effective,land use applications for development may be submitted to the city
for review.
Implementation Documents
The River Terrace Funding Strategy is a critical implementation document. As previously stated, the
funding strategy was developed concurrently with the Community Plan pursuant to state and regional
requirements and is expected to be adopted with the Community Plan. Additional implementation
projects are described below.
City of Tigard Page 1-5
RIVER TERRACE COMMUNITY PLAN
Community Plan Implementation
The city identified a number of implementation projects in the course of the River Terrace community
planning process.All are necessary for Community Plan implementation,but some have broader
citywide implications.A summary of these implementation projects is provided below.
River Terrace Code Amendments
This effort includes only those amendments that were identified through the community planning
process and that are critical to the initial implementation of the Community Plan.They include targeted
changes to the city's Planned Development regulations related to open space requirements,new text and
graphics to implement the River Terrace Boulevard design concept,and updates to the city's adequate
facility requirements. Other code amendments will likely follow later,such as site and building design
standards for the Community Commercial area.
River Terrace Public Improvement Design Standards
This effort includes only those additions and updates that were identified through the community
planning process and that are critical to the initial implementation of the Community Plan,such as the
development of River Terrace Boulevard planting standards.Once completed and publicly reviewed,
these updates will be adopted into the city's existing Public Improvement Design Standards. Other
additions and updates will likely follow later.
Citywide Stormwater Model and Standards
A new flow duration based model and new stormwater standards and design guidelines are being
developed in coordination with Clean Water Services. Once completed and publicly reviewed, they will
be adopted into the city's existing Public Improvement Design Standards.The new stormwater model
will apply to stormwater management citywide. The new stormwater standards and design guidelines
will initially only apply to River Terrace due to the unique conditions and stormwater management
strategies identified in the River Terrace Stormwater Master Plan.They may eventually apply on a
citywide basis in the future.
Citywide Infrastructure Financing Project
This project includes an evaluation of the city's existing utility fees and System Development Charges
(SDC) and associated SDC credit policies. It will make recommendations about the need for new
and/or increased fees and SDCs and associated SDC credit policies. Each infrastructure system will be
analyzed separately.All fees and SDCs will likely apply on a citywide basis,although some may be
specific to River Terrace.
In addition to these projects,the recommended action measures at the end of each Community Plan
section and the various River Terrace infrastructure master plans also identify implementation tasks
and/or needs. While every effort has been made to identify all relevant near-and long-term tasks that
are necessary for the successful implementation of this Community Plan,it is anticipated that additional
tasks and/or needs will be identified during the development of River Terrace,which is expected to
occur incrementally over the course of the next two or more decades.
Existing Conditions
Existing conditions provide the physical basis for land use planning in River Terrace.Topographical and
geological conditions and existing infrastructure influence the location,size,and type of future
development,public facilities,parks and streets. A summary of these conditions are included below.
More detailed information can be found in the various studies that were conducted during the course of
the concept and community planning processes,including but not limited to the West Bull Mountain

Natural Resources Inventory (Pacific Habitat Services,2008),Regional Landslide Hazard Mapping,
West Bull Mountain Planning Area (DOGAMI,2008),and the River Terrace Tree Grove Assessment
Report(Winterbrook,2013).
Transportation Context
River Terrace is located at the cross roads of Roy Rogers Road and Scholls Ferry Road,two regionally
significant roads that connect River Terrace to Tigard,Beaverton,Sherwood and beyond. River Terrace
is also served by Beef Bend Road to the south and 150th Avenue along its eastern edge. Bull Mountain
Road provides east-west circulation through the center of River Terrace. Roy Rogers Road,Bull
Mountain Road and 150th Ave are

�+O L L F N wn agricultural lands of the Tualatin
x Valley. Unlike the broad and
4 WLL k relatively flat lands of the valley,
r TU River Terrace is situated on the
western and southern slopes of
Bull Mountain and is characterized
by rolling topography interspersed
with steeply sloped lands that were
created over time by erosion.The steepest slopes generally occur along existing tributaries that drain to
the Tualatin River,which is to the south and west of River Terrace. The northern part of River Terrace
contains the largest concentrations of relatively flat land.The southern area contains more steeply
sloped land.Flat land is generally more conducive to higher density development than steeply sloped
land.Additionally,water,sewer and stormwater facilities rely on and/or utilize topography for efficient
delivery of services.The sections on Land Use and Public Facilities provide more detailed information
on the types and locations of land uses and public facilities that are recommended in River Terrace,
which are,in part,based on existing topography.
Natural Resource Context
River Terrace contains a number of protected natural resources,including wetlands,streams,riparian
corridors and significant tree groves. River Terrace contains a total of ten natural drainageways and one
significant wetland.These natural resources provide wildlife habitat,help prevent erosion and contribute
to water quality.The section on Natural Resources provides more detailed information on the types and
locations of natural resources that are protected in River Terrace.
City of Tigard Page 1-7
RIVER TERRACE COMMUNITY PLAN
Geological Context
River Terrace is characterized by shallow bedrock and clayey soils,which are highly erodable.As a
result,the potential for stormwater infiltration is poor and also potentially problematic for slope stability
given the steep terrain and proximity to shallow bedrock.The Public Facilities section on stormwater
provides more detailed information about how the Community Plan responds to these conditions.

RIVER TERRACE COMMUNITY PLAN
Goal 1: Citizen Involvement
Hearing from community members is a key component of
building a livable community.The River Terrace Community
Plan public involvement effort sought to engage a wide range Continuing Involvement
of community members and project stakeholders in planning Public involvement in the River
for River Terrace. Following from Tigard's public Terrace Community Plan built upon
involvement goals,multiple opportunities were provided for the West Bull Mountain Concept Plan
participation,communication and information throughout the public involvement efforts.
planning process. In addition,several new outreach tools were
used to engage the public.
The River Terrace community planning process built upon Washington County's public involvement
efforts during the West Bull Mountain concept planning process,giving stakeholders the opportunity to
stay involved as planning responsibilities shifted from Washington County to the City of Tigard. Public
involvement led to several key River Terrace Community Plan and infrastructure master plan
refinements,which are as follows:
■ Transportation impacts on existing adjacent Bull Mountain neighborhoods were mitigated in a
number of ways to address traffic concerns.The main north-south street parallel and to the east
of Roy Rogers Road was changed from a Neighborhood Route to a Collector Street (aka River
Terrace Boulevard),a signal was proposed at the Scholls Ferry Road/River Terrace Boulevard
intersection,and the Luke Lane connection was modified to only connect via a circuitous route.
■ A design concept for River Terrace Boulevard was advanced that effectively addressed concerns
about balancing mobility with safety and comfort for all modes of travel. Key design elements
include the River Terrace Trail,a wide landscaped median and sidewalk bulbouts to support
large trees,on-street parking to calm traffic,and design standards for street-facing facades and
yards to ensure a high-quality and safe public realm.
■ The greenway trail along Roy Rogers Road and Scholls Ferry Road was eliminated for a number
of reasons.The main one being that most stakeholders preferred the location of the River
Terrace Trail and felt that the inclusion of both was neither feasible nor necessary given the
proximity of both trails to each other.
■ Land acquisition for a northern community park east of Roy Rogers Road was prioritized in
anticipation of near-term development needs and in response to community feedback. The latter
involved locating a community park near existing adjacent neighborhoods to help offset the
transportation impacts that they will likely experience when street connections are made.
■ The location of the commercial area was stretched towards Roy Rogers Road to address
concerns about its visibility and future viability.
■ Lower density residential zones were strategically located along the area's eastern and northern
edges to provide a buffer between existing lower density neighborhoods in Bull Mountain and
future higher density neighborhoods in River Terrace.
■ Various implementation strategies were identified to address the challenges associated with
regional stormwater facility implementation that provided needed flexibility for developers.All
identified strategies maintained the benefits of a regional facility approach to stormwater
management.
City of Tigard Page 2-1
RIVER TERRACE COMMUNITY PLAN
■ The Leeding Lane connection was downgraded from a vehicle connection to a
pedestrian/bicycle connection to address concerns about impacts to an existing wetland.
Participation
Advisory Committees
A Stakeholder Working Group (SWG) and Technical Advisory Committee (TAC) were formed to
provide advice and guidance during the community planning process.
An eighteen-member SWG,made up of property owners,developers,neighborhood representatives,
affected agencies and community organizations,was appointed by Tigard City Council to provide on-
going advice and feedback to the project team.This was the primary advisory group to the project team
during the development of the Community Plan. The group convened in spring of 2013 and met
thirteen times between March 2013 and November 2014. All members on the county's West Bull
Mountain Concept Plan SWG were invited to participate on the city's River Terrace Community Plan
SWG. In addition to the SWG,an Implementation Subcommittee of the SWG,comprised of developers
on the SWG,met on an ad hoc basis for the purpose of discussing specific development plans and
implementation issues.
The TAC,made up of technical staff from the City of Tigard,City of Beaverton,Clean Water Services,
Washington County,Metro,Department of Land Conservation and Development, Oregon Department
of Transportation and other affected agencies and jurisdictions provided subject matter expert advice
and review throughout the process.They met a total of nine times between September 2012 and April
2014.
Community Meetings
From October 2012 to April 2014,the River Terrace project team hosted five public meetings that
focused on the Community Plan and the five related infrastructure master plans. In total,attendance
was over 150 people. Input was sought on issues ranging from land use to the River Terrace Boulevard
design concept. Outcomes from each meeting were presented to the SWG in advance of their decision
on the matter. In addition,public comment opportunities were provided at each SWG meeting.
In October 2014, the project team hosted a series of three meetings that focused on discussing and
refining the River Terrace Funding Strategy.
Consider.lt Online Deliberation
The project team piloted a new online engagement tool called Consider.It.This emerging social
technology allows hundreds of people to deliberate together online on a single issue. Five questions
were posed for deliberation,and 166 different comments were collected.The questions are as follows:
■ Should Tigard redirect existing funding instead of raising new taxes/fees to fund River Terrace
infrastructure in the short term?
■ Should the proposed River Terrace Transportation System be forwarded to City Council for
adoption?
■ Should Tigard work to provide more pedestrian amenities in River Terrace than normally
required by city code?
■ The question of whether to install a new traffic signal on Scholls Ferry Road east of Roy Rogers
Road has many trade-offs and is not clearly answered with technical analysis. Do you support or
oppose a traffic signal in this location?
■ Should Council adopt the recommended funding scenarios for infrastructure in River Terrace?

involvement.No new goals or policies are needed to implement the citizen involvement
recommendations for River Terrace.
Public involvement led to several key River Terrace Community Plan and infrastructure
master plan refinements.
RECOMMENDED ACTION MEASURES
1. Establish a City of Tigard Neighborhood Network Program Area covering River Terrace.
2. Continue to engage with unincorporated Bull Mountain residents,in partnership with
Washington County,as the Community Plan is implemented and development occurs.
3. Continue to use the River Terrace website to update project stakeholders and community
members as the Community Plan is implemented and development occurs.

RIVER TERRACE COMMUNITY PLAN
Goal 2: Land Use Planning
Land use planning influences the type and character of development in the city and contributes to the
community's quality of life,sense of place and economic vitality. Land use planning also enables the city
to provide and sustain essential urban services and lays the groundwork for coordinating and partnering
with other local governments and agencies that have a stake in the overall well-being of the Portland
Metro Region.
The goals and policies contained in the Tigard Comprehensive Plan provide the basis for the city's land
use planning program.The River Terrace Community Plan is a product of this program and an ancillary
Comprehensive Plan document. It also provides the specific development vision for this area,one that
was both prescribed by Metro when River Terrace was added to the Urban Growth Boundary(UGB)
and envisioned by the community through the community planning process.
Metro Requirements
Metro set targets for residential development in River Terrace in order to accommodate the long-range
growth in population anticipated in the Portland Metro Region.' The portion of River Terrace that was
added to the UGB in 2002,i.e.Areas 63 and 64,is required to have an average residential density of at
least ten units per net residential acre.'The portion of River Terrace that was added to the UGB in
2011,i.e. Roy Rogers West(also referred to as Area 4),is required to provide zoned capacity for a
minimum of 479 dwelling units.'Pursuant to Metro policy, some of the required units in Roy Rogers
West can be added to Areas 63 and 64 as long as the average residential density requirement for Areas
63 and 64 is met without these additional units.
The city initially adopted Comprehensive Plan designations for

During the River Terrace community planning process,refinements were made to the recommended
WBMCP land uses in order to support a better range and mix of zoning districts and,by extension,
housing types.These refinements were vetted by stakeholders,are consistent with the density
assumptions and guidelines in the concept plan,and meet Metro's required residential densities for each
area. Comprehensive Plan designations for River Terrace are shown on Map 1 at the end of this
document. They include Low-Density Residential,Medium-Density Residential,Medium High-Density
Residential,Community Commercial,Public Institution and Open Space. Adoption of the Community
Plan does not result in the adoption of these designations. Adoption of Comprehensive Plan
designations requires a separate action.
River Terrace zoning districts are consistent with the Comprehensive Plan designations described above
and are provided on Map 2 at the end of this document.They include R-4.5,R-7,R-12,R-25 and

RIVER TERRACE COMMUNITY PLAN
Community Vision
Much of the land use vision for River Terrace came from the WBMCP,which is incorporated by
reference here.Aspects of this vision were more fully developed during the community planning
process and can be found in the River Terrace Park System Master Plan Addendum,River Terrace
Transportation System Plan Addendum and River Terrace Stormwater Master Plan. In general, the
River Terrace Community Plan provides for a variety of land uses and residential densities consistent
with the community's desire to create a community of great neighborhoods that includes housing,
neighborhood-scale commercial businesses,schools,parks and recreational opportunities. Key elements
of this vision are summarized below.
■ River Terrace is primarily a residential community that includes a mix of residential densities.This
allows for a variety of housing types that meet a wide range of housing needs.
■ Higher residential densities are planned near commercial and institutional uses and along major
corridors.Lower residential densities are planned in areas with steep slopes and along the area's
eastern and northern edges to provide a buffer between existing lower density neighborhoods
and future higher density neighborhoods.
■ The commercial area is sized and zoned to provide neighborhood-scale commercial goods and
services. It is located at the intersection of two Collector Streets,one of which is River Terrace
Boulevard,7 and along Roy Rogers Road to facilitate its success and vitality.The commercial area
is envisioned as a vibrant mixed-use center that is pedestrian-oriented and utilizes high-quality
design elements and materials.
■ The mull-modal transportation system is designed to connect River Terrace to existing and
future neighborhoods,services,parks, schools and regional destinations through a hierarchy of
streets and trails that provide residents and visitors with convenient,safe and comfortable travel
options.
■ Parks and trails are distributed throughout the area to provide a variety of convenient recreational
opportunities for residents and visitors. In combination with the neighborhood commercial area
in the north and the school site in the south,these uses provide important public spaces for
residents and visitors to meet,recreate and shop together.
■ The co-location of land uses (e.g. parks and trails),public facilities (e.g. stormwater facilities and
pump stations),and natural resource areas is strongly encouraged to maximize the efficient use of
land and to create opportunities for community amenities.
KEY FINDINGS
w The River Terrace Community Plan supports the city's adopted land use goals and policies.
No new goals or policies are needed to implement the land use recommendations for River
Terrace.
w The River Terrace Community Plan utilizes the city's existing Comprehensive Plan and
zoning district designations.
w Comprehensive Plan and zoning district designations are provided in the Community Plan
for informational purposes only.Adoption of the Community Plan does not result in the
adoption of these designations.Adoption of these designations requires a separate action.

w Comprehensive Plan and zoning district designations determine the type,number and
location of residential dwelling units in River Terrace.This information was used to help
determine the size and location of needed public facilities and services,which are more fully
described in the sections on Parks,Public Facilities and Transportation and in the five
infrastructure master plans developed for River Terrace.
w Implementation of the commercial area vision,including the design concept for River
Terrace Boulevard,will require amendments to the Community Development Code and the
Public Improvement Design Standards.
RECOMMENDED ACTION MEASURES
1. Adopt the Comprehensive Plan and zoning district designations shown on Maps 1 and 2
respectively.
2. Amend the Community Development Code and the Public Improvement Design Standards
to implement the commercial area vision and design concept for River Terrace Boulevard.

RIVER TERRACE COMMUNITY PLAN
Goal 5: Natural Resources
The Tigard Comprehensive Plan recognizes that as the city's population continues to grow,so does the
potential for conflict between the desire to preserve valuable natural resources and the need to provide
adequate land for development.As development patterns in River Terrace change from rural to urban
uses to accommodate growth,more pressure will be placed on the area's abundant natural resources.
This tension between the built and natural environments underscores the need to effectively balance
development in River Terrace with natural resource protections.
Protection of natural resources preserves their aesthetic and environmental benefits. It also contributes
to the health,safety and welfare of existing and future residents. The city's natural resource protection
goals,policies and regulations must meet Statewide Planning Goal 5 requirements for resource
protection and Metro Functional Plan Titles 3 and 13 requirements for water quality and habitat
protection. In addition,they must comply with applicable federal,state and regional laws that protect
sensitive,threatened and endangered species and their habitats.
Protecting natural resources in River Terrace requires the extension of several existing city resource
protection programs out to River Terrace. Implementation of these programs will occur through the
adoption of several inventories and maps that provide various levels of natural resource assessment and
protection as well as development flexibility. Natural resource protection will also be achieved through
the development of effective stormwater management facilities that protect the community's water
supply and the health and function of stream corridors for habitat and recreation.The River Terrace
Stormwater Master Plan, for example,contains strategies for utilizing existing wetlands and stream
corridors that enhances and protects them while also providing a stormwater management function.
There is a strong relationship between natural resource
protection and stormwater management. Generally,they Why Protect Natural Resources?
share some similar goals,such as preserving existing Protection of natural resources preserves
hydrology and mature native vegetation. Specifically,they their aesthetic and environmental benefits. It
both provide for the preservation of large tree groves and also contributes to the health,safety and

stormwater runoff from development.
While River Terrace will be able to utilize the same natural resource protection programs as the rest of
the city,the Community Plan recognizes that River Terrace has some unique and challenging existing
conditions in and around its natural resource areas,such as steep slopes and erodable stream corridors.
The River Terrace Stormwater Master Plan responds to these conditions by recommending specific
strategies that are tailored to the needs and characteristics of each drainage basin in the area.
Additionally,the city intends to adopt a new continuous simulation hydrologic model in partnership
with CWS to provide better stream protection in River Terrace than exists under the current model.
More information about the River Terrace Stormwater Master Plan can be found in the section on
Public Facilities.
The following natural resources are addressed in this section:
■ Fish and Wildlife Habitat
■ Wetlands
■ Streams
■ Tree Groves.

RIVER TERRACE COMMUNITY PLAN
Fish and Wildlife Habitat
A number of agencies are involved in the effort to address the management and protection of fish and
wildlife habitat.The City of Tigard partners with other local jurisdictions as part of the Tualatin Basin
Partners for Natural Places,an alliance between Washington County and local cities (including Tigard)
working with Metro,Tualatin Hills Parks and Recreation District,and Clean Water Services,to meet
relevant federal,state,and regional requirements.
As a result of this partnership,the city has an adopted

The habitat inventory for River Terrace shows that it has 13.3 acres of habitat designated as "highest"
value (i.e. Metro inventoried Class I and II riparian resources within the Clean Water Services Vegetated
Corridor).An estimated 40.3 acres of Class I and II riparian habitat situated outside the Clean Water
Services'vegetated corridor are designated as "moderate"value. In addition, 132.16 acres of non-Class I
and II riparian resources within River Terrace are designated as "lowest"value,including both upland
and lower-value riparian habitat areas.

brought to light that while residents prioritize tree grove preservation,the city's large groves were
disappearing. The Tree Grove Preservation Program provides flexible standards and incentives to
facilitate the preservation of the city's remaining groves.
As part of this community planning effort,the city will update its Significant Tree Groves Map to
include River Terrace.This technical work was completed in early 2013 by the City of Tigard.This will
allow development in River Terrace to take advantage of the Tree Grove Preservation Program
incentives. Map 5 at the end of this document shows the location of the significant tree groves in River
Terrace.
A tree grove is defined as a stand of trees that are predominantly 25 feet or more in height with
contiguous canopy cover of one acre or more in area. Tree groves generally do not include linear
plantings that are one or two trees wide (e.g. street trees or rows of trees along a property line) or
fragmented (e.g. treed areas with a high proportion of canopy broken by houses,roads or other
development).Technical work identified nine significant tree grove sites totaling 61 acres within River
Terrace.The sites cover 12%of the planning area and range from two to 18 acres in size.
KEY FINDINGS
The River Terrace Community Plan supports the city's adopted natural resource goals and
policies. No new goals or policies are needed to implement the natural resource
recommendations for River Terrace.
The city's existing natural resource protection programs will be applied in River Terrace.
River Terrace has 186 acres of identified significant habitat area.
River Terrace has one significant wetland and several local wetlands.
River Terrace has several stream corridors with associated wetlands and riparian areas
totaling approximately 65 acres.
River Terrace has nine significant tree grove sites totaling 61 acres.
The city intends to adopt a new continuous simulation hydrologic model in partnership with
CWS to provide better stream protection in River Terrace than exists under the current
model.
River Terrace has some unique and challenging existing conditions in and around its natural
resource areas,such as steep slopes and erodable stream corridors.The River Terrace
Stormwater Master Plan responds to these conditions by recommending specific strategies
that are tailored to the needs and characteristics of each drainage basin in the area.
RECOMMENDED ACTION MEASURES
1. Update the city's natural resource maps to include inventoried resources in the River Terrace
area.This includes updating the city's:
a. Significant Habitat Areas Map
b. Local Wetlands Inventory and Map
c. Wetlands and Riparian Areas Map

Goal 8: Parks, Recreation, Trails, and Open Space
Parks,trails and open spaces and access to recreational activities serve many different important
community purposes as described in the Comprehensive Plan. Planning for the provision of these types
of public facilities in River Terrace furthers the city's goal of providing a wide variety of recreational
opportunities for new and existing residents through a diverse system of parks,trails and open spaces. It
also meets Metro Functional Plan Title 11 and Statewide Planning Goal 8 requirements for ensuring that
areas like River Terrace,which have been brought into the Urban Growth Boundary (UGB) for urban
development purposes,are efficiently urbanized and developed as complete communities.

RIVER TERRACE COMMUNITY PLAN
The city has a unique opportunity in River Terrace to provide parks,open spaces and trails consistent
with its adopted LOS standards due to the fact that,unlike the rest of the city,River Terrace is largely
undeveloped.'Additionally,it contains many existing natural resources,which provide the area with an
abundance of protected open spaces,and it will eventually need several large stormwater facilities,which
can be designed to serve recreational purposes as well as manage runoff.
Despite these opportunities,implementing the vision for public parks and trails in River Terrace will not
be without its challenges.The city has no existing legal mechanism for exacting park land,with the
exception of the Planned Development process in the Community Development Code. However,there
are a variety of implementation strategies that could be utilized to meet the city's LOS standards in River
Terrace. Examples include:
■ prioritizing land acquisition to preserve land for future park and trail use
■ leveraging active transportation grants for trails
■ utilizing development agreements
■ requiring co-location of public facilities wherever practicable
■ working with the Tigard-Tualatin School District to allow public use of recreational facilities on
school property
The innovative design concept for River Terrace Boulevard is an example of a co-location
implementation strategy.The River Terrace Trail is co-located with the boulevard for approximately 1.5
miles of its 2.25-mile length.
As shown on Map 8 at the end of this document,two trails3 are recommended in River Terrace.The

of internal and external destinations,including but not limited to other planned and proposed regional
trails. Due to its length,location and connections, this trail is expected to have a high level of use and
should be designed accordingly,such as with a sufficiently wide paved surface.The second and shorter
trail in River Terrace,identified as the Southern Access Trail,is less than a mile long and is located in
the southern part of River Terrace. It provides local access between existing adjacent neighborhoods to
the east and River Terrace neighborhoods to the west.As such,it is expected to have a lower level of
use than the River Terrace Trail.Both trails are envisioned as off-street facilities wherever possible and
where not immediately adjacent to a Collector Street or Neighborhood Route.
KEY FINDINGS
The River Terrace PSMP Addendum and,by extension,the River Terrace Community Plan
support the city's adopted park goals and policies. No new goals or policies are needed to
implement the park and trail recommendations for River Terrace.
The city needs to develop and implement a multi-pronged approach to acquiring and developing
land for public park and trail development in order to adequately provide for the recreational

needs of future River Terrace residents,including but not limited to those discussed in the River
Terrace PSMP Addendum.This will likely involve developing and/or leveraging a variety of
funding sources and entering into site specific negotiations with developers and the school
district before and during the land use and development review process.
• The city has no existing legal mechanism for exacting park land,with the exception of the
Planned Development process in the Community Development Code. The city's Planned
Development(PD) open space requirements are not aligned with the LOS standards contained
in the City of Tigard PSMP or the River Terrace PSMP Addendum.The PD process could help
implement the community's vision for parks and trails in River Terrace if its open space
requirements were better aligned with the River Terrace PSMP Addendum.
IIIIIII, Park and trail development,open space preservation,natural resource protection and regional
stormwater facility development are inextricably linked in River Terrace as envisioned by the
community and described in the River Terrace PSMP Addendum and River Terrace Stormwater
Master Plan.There are many existing natural resource areas and several future regional
stormwater facilities that would benefit from co-location with parks,trails and/or open spaces.
w Implementation of the design concept for River Terrace Boulevard,which includes the River
Terrace Trail,will require amendments to the Community Development Code and the Public
Improvement Design Standards.
w Two distinct trails are proposed in River Terrace.The River Terrace Trail is designed and
located to serve River Terrace and the broader region over relatively flat terrain. The Southern
Access Trail is envisioned as a local trail that serves the southern part of River Terrace and
existing adjacent neighborhoods to the east.
w Existing adjacent Bull Mountain neighborhoods are park deficient and will benefit from park
and trail development in River Terrace.
RECOMMENDED ACTION MEASURES
1. Prioritize the acquisition of suitable land for future park and trail development in the River
Terrace Funding Strategy. In the near term,actively pursue acquiring land for a northern
community park on the east side of Roy Rogers Road while River Terrace is largely
undeveloped.
2. Work with the Tigard-Tualatin School District to explore the possibility of allowing public
use of recreational facilities on the site of the future school.
3. Amend the Community Development Code to better align the open space requirements for
Planned Developments in River Terrace with the River Terrace PSMP Addendum.
4. Look for opportunities to create parks and open spaces within River Terrace alongside
and/or within existing natural resource areas and future regional stormwater facilities
consistent with the city's park and open space goals,the River Terrace Stormwater Master
Plan,and the River Terrace PSMP Addendum.
5. Look for opportunities to create trail connections within River Terrace and between River
Terrace and existing adjacent neighborhoods along existing stream corridors and within
future regional stormwater facilities consistent with the city's natural resource protection
goals,the River Terrace Stormwater Master Plan,and the city's Strategic Plan for walkability.

RIVER TERRACE COMMUNITY PLAN
Goal 10: Housing
Almost 97% of the buildable land in River Terrace is proposed for new housing.
The city's role in planning for housing includes:
■ Housing Capacity: Ensuring an adequate supply of residential land is available;
■ Service Delivery: Providing public facilities and services (see Public Facilities section);
■ Development Regulations: Regulating design and density;
■ Affordable Housing: Supporting low and moderate income housing through funding,incentives
and information sharing;and
■ For River Terrace: Integrating River Terrace into the city's overall efforts to plan for needed
housing.
Housing Capacity
In the Portland metropolitan region,only land included in the Urban Growth Boundary (UGB),an
invisible line that separates rural and urban land,can be developed at residential densities requiring
urban services. State and Metro requirements focus on increasing a local jurisdiction's housing capacity
in order to make efficient use of land and urban services within the UGB.
At the local level,each county and city must inventory its buildable lands,which is defined as vacant and
re-developable land suitable for residential use,to determine housing capacity. A citywide analysis of
housing needs and capacity conducted in 2012 found that the city has capacity for approximately 7,000
new housing units on buildable lands zoned for residential development within the city's UGB,
compared to an estimated need for just over 6,500 new units during the next 20 years.
Figure 6-1: Buildable Land in River Terrace
City of Tigard Page 6r1
RIVER TERRACE COMMUNITY PLAN
The table below summarizes the housing capacity planned for River Terrace. Over 50% of the city's
overall estimated capacity (3,744 housing units') could be absorbed by River Terrace development.

Development Regulations
Initial planning for the River Terrace area envisioned "A Community of Great Neighborhoods,"
including a range of residential densities to provide diverse housing types,a variety of housing choices,
and integration with existing adjacent Bull Mountain neighborhoods.
The Tigard Comprehensive Plan echoes the same sentiment for all neighborhoods in Tigard with
policies that call for:
■ "...Opportunities for a variety of housing types to meet the diverse housing needs of current and
future city residents."
■ "...Measures to mitigate the adverse impacts from differing,or more intense,land uses on
residential living environments..."
1 The River Terrace infrastructure master plans assume a total of 2,587 dwelling units for infrastructure planning
purposes. in addition to eliminating constrained lands and estimated rights-of-way, the dwelling unit calculation utilized
by these master plans also eliminates committed lands. Removal of such lands,e.g.future park and school sites, is
appropriate for infrastructure planning purposes.It is not however,consistent with the city or Metro's approach for
performing a housing capacity analysis.
2 Net acres were calculated by eliminating constrained lands(i.e. slopes exceeding 25%and Metro Title 3 protected water
features and vegetated corridors)and an estimated amount of acreage for rights-of-way(i.e. 20%).
3 Estimated housing capacity was calculated by dividing the net acres in each zone by the minimum square footage
required for each lot in that zone.

Affordable Housing
Providing housing options is a priority citywide,including in River Terrace. For this reason, the city will
apply its existing affordable housing program to River Terrace,with updates to the citywide program
expected in 2015.
In general, there is a need for less expensive ownership and rental units in Tigard,according to the city's
2012 housing study. This is not uncommon,as the lowest income households struggle to find housing
of any type that keeps costs at 30%of gross income. This means that low to moderate income families
are at risk of needing to spend a large portion of their income on housing,which may not leave enough
for other essentials.
According to recent studies,when affordable housing is included
in the range of housing choices it is good for everyone. A 2011 Meeting Housing
study by the Center for Housing Policy links the presence of Focus Group Objectives

Non-Land Use Strategies in Place
■ A tax abatement program for owners or leaseholders of property used to provide affordable
housing.This may allow reduced rents or reduced monthly homeowner housing costs.
■ A budget set-aside to reduce fees and charges imposed on affordable housing development.
■ Financial support for the operation of the Tigard-based Good Neighbor Center homeless shelter
located on Greenburg Road.
■ Identification and pursuit of available grants to fund public improvements serving low income
neighborhoods and areas that include affordable housing.
■ A Housing Inspection Program to maintain the quality of the city's existing housing stock.
■ An Enhanced Safety Program,administered through the Tigard Police Department,to reduce
crime and increase the livability of rental properties.
■ Membership in the County-wide Housing Advocacy Group,which monitors affordable housing
throughout Washington County.
Housing Code Updates
The Tigard Goal 10 Housing Strategies Report made several recommendations the city could undertake
to prepare for future housing development in Tigard.A project to implement these code updates is
scheduled to begin in 2015.These strategies include:
• Update the City's Development Code to include provisions for"cottage clusters" and "live-
work"housing units;
■ Enhance provisions and standards related to accessory dwelling units and single family
attached housing;
■ Refine parking requirements for senior and affordable housing developments in existing
or future high capacity transit areas;and
■ Provide for density or height bonuses to promote affordable housing in selected areas.
■ Implement a variety of zoning and market-based strategies to promote development of a range of
housing types in newly developing or future mixed use areas,including River Terrace.
■ As part of various planning,development and permitting processes,provide information to
housing developers,home builders and landlords regarding fair housing goals and requirements,
as well as design practices that help ensure accessibility for people with physical or mobility
limitations,including older residents.
Metropolitan Housing Rule Compliance
The Metropolitan Housing Rule (OAR 660-007/Division 7) establishes regional residential density and
housing mix standards for communities within the Metro UGB.Tigard must provide the opportunity to
build new housing at an overall average density of 10 or more dwelling units per net buildable acre.
Tigard must also designate sufficient buildable land that allows for at least 50%of new residential units
to be attached housing(either single-or multi-family attached).
An analysis of housing needs and capacity conducted in 2012 found that the city's overall zoning is in
compliance with both Metropolitan Housing Rule components.Table 3-1 shows the residential density
calculations for River Terrace,where the overall density is 10.84 and 11.76 dwelling units per net
buildable acre for Areas 63 &64 and Roy Rogers West,respectively. Thus,the requirement to average
City of Tigard Page 6-5
RIVER TERRACE COMMUNITY PLAN
10 or more dwelling units per net buildable acre is met. Moreover,all of the zoning districts in River
Terrace (R-4.5, R-7,R-12 and R-25) permit single-family detached as well as single-family attached
and/or multi-family housing.Thus,the opportunity for attached housing exists throughout River
Terrace.`
KEY FINDINGS
w The River Terrace Community Plan supports the city's adopted housing goals and policies.
No new goals or policies are needed to implement the housing recommendations for River
Terrace.
Almost 97%of the buildable land in River Terrace is proposed for new housing.
Over 50% of the city's overall estimated capacity could be absorbed by River Terrace
development.
River Terrace stakeholders prioritized a range of residential densities to provide diverse
housing types,a variety of housing choices,and integration with existing adjacent Bull
Mountain neighborhoods when designing the land use framework for River Terrace.
w The city will apply its existing affordable housing program to River Terrace,with updates to
the citywide program expected in 2015.
w The River Terrace Community Plan complies with the Metropolitan Housing Rule (OAR
660-007/Division 7).
RECOMMENDED ACTION MEASURES
1. Adopt the Comprehensive Plan and zoning district designations described in the section on
Land Use to facilitate a mix of residential densities that allows for a variety of housing types
in order to comply with the Metropolitan Housing Rule and to meet a wide range of housing
needs.
2. Update the city's affordable housing program.
Consistent with the city's 2012 Population and Housing Review, duplexes were considered multi family housing for the
purpose of analysis. Duplexes are permitted conditionally in the R-4.5 zone. Because they are a conditional use,the 2012
analysis considered it unreasonable to assume that all of the buildable R-4.5 zoned land would develop as duplexes.
Instead,for this zone, it was assumed that half of the land would develop as single-family detached housing and half
would develop as duplexes. If this some assumption were made in River Terrace, only 148 units would be assumed to not
develop as attached housing.

RIVER TERRACE COMMUNITY PLAN
Goal 11: Public Facilities and Services
One of the principal goals of the River Terrace Community Plan,in conjunction with the River Terrace
Funding Strategy,is to provide a framework for urban development through the timely,orderly and
efficient provision of public facilities and services in River Terrace. Planning for the provision of public
facilities and services in this manner furthers the city's goal of facilitating development in River Terrace
and safeguards the health,safety and welfare of the city's newest residents. It also meets Metro
Functional Plan Title 11 and Statewide Planning Goal 11 requirements for ensuring that areas like River
Terrace,which have been brought into the Urban Growth Boundary(UGB) for urban development
purposes,are efficiently urbanized and developed as complete communities.
For the purposes of this chapter,public facilities and services refers to stormwater management,water
supply and distribution,sanitary sewer management,community facilities and solid waste disposal.
Public facilities for recreation and transportation are discussed in the sections on Parks and
Transportation respectively.
Three distinct infrastructure master plans were created as part of the community planning process to
address public facility needs in River Terrace for stormwater management,water supply and
distribution,and sanitary sewer management.They are as follows:
• River Terrace Stormwater Master Plan
■ River Terrace Water System Master Plan Addendum
■ River Terrace Sanitary Sewer Master Plan Addendum
The water and sanitary sewer master plans append existing citywide master plans.The stormwater
master plan exists as a standalone document since the city does not have a citywide master plan for
stormwater.
The following public facilities and services are addressed in this section.
■ Stormwater Management
• Water Supply and Distribution
■ Sanitary Sewer Management
■ Community Facilities
■ Solid Waste Disposal
Stormwater Management
Stormwater management facilities are needed to protect the quality of our community's water supply,
the built environment from flood damage during large storm events,and the health and function of
stream corridors for habitat and recreation.The following stormwater management goals were utilized
in the development of the River Terrace Stormwater Master Plan.
■ Restore/enhance vegetated corridors
■ Protect water quality
■ Preserve existing hydrology
■ Promote safe and long-lasting stormwater facilities
City of Tigard Page 7-1
RIVER TERRACE COMMUNITY PLAN
■ Balance the use of regional and on-site stormwater facilities
■ Preserve existing mature vegetation
■ Maximize use of multi-functional facilities to create community amenities
■ Promote partnerships with other public service providers and agencies
The recommended stormwater management strategies for River Terrace support these goals and have
been incorporated into the master plan based upon the needs and characteristics of each drainage basin
in the area.These strategies make use of existing topography,natural systems and facility design to
effectively and efficiently ensure that: (1) all stormwater runoff from development is treated before it
enters a stream,river or wetland,and(2) the amount of stormwater runoff anticipated from
development is appropriately managed through either detention and/or conveyance to prevent stream
erosion and property damage.The former objective is about protecting water quality,while the latter
objective is about managing water quantity.
The strategies recommended in the River Terrace Stormwater Master Plan are based upon Clean Water
Services (CWS) Design and Construction Standards and the CWS Low Impact Development
Approaches (LIDA) Handbook. In addition,it reflects the city's intention to adopt new design
standards for the River Terrace area in collaboration with CWS on or before the adoption of the
Community Plan.The need for these new standards is based upon the following.
■ The city's recent experiences dealing with channel stability problems elsewhere on Bull Mountain,
and the presence of similar drainage channel conditions in River Terrace.
■ The city's decision to develop a new continuous simulation model for this area.
■ Anticipated changes to CWS's Design and Construction Standards to address pending
requirements under their National Pollutant Discharge Elimination System(NPDES) permit.
■ The community's desire to preserve and protect existing natural resources in the River Terrace
and Bull Mountain area.

w Stormwater facilities are recommended outside River Terrace and the UGB due to soil,
bedrock and slope conditions.Stormwater facilities located outside the UGB must address
land use regulations from the Washington County Community Development Code Sections
340-4.1 and 430-105.3 through 430-105.7;Oregon Revised Statute 215.275;and Oregon
Administrative Rule 660-33.
w Expansion of the UGB to include the Urban Reserve Area south of River Terrace and north
of Beef Bend Road would provide more opportunities for stormwater management in River
Terrace than currently exist.
RECOMMENDED ACTION MEASURES
1. Adopt the necessary elements of the River Terrace Stormwater Master Plan and the River
Terrace Funding Strategy into the Comprehensive Plan to meet the city's PFP requirement
under Statewide Planning Goal 11 when all elements of the citywide PFP have been
developed.
2. Work with the development community to fund the regional stormwater facilities in an
equitable,efficient and effective manner per the recommendations in the River Terrace
Funding Strategy.
3. Work with CWS to develop a continuous simulation hydrologic modeling tool for use in
River Terrace consistent with advancements in stormwater management practices.
4. Develop stormwater design standards and guidelines for regional stormwater facilities in
River Terrace that minimize their operational costs,guide their development as community
amenities and multi-functional facilities,and allow for needed flexibility in implementation.
5. Work with Metro to bring the Urban Reserve Area south of River Terrace and north of Beef
Bend Road into the UGB and/or work with DLCD,Washington County and other affected
agencies to obtain the necessary approvals to construct a high-flow conveyance system
outside the UGB.
6. Conduct a conceptual design and alternatives analysis for the recommended high-flow
conveyance system that evaluates the advantages,disadvantages and permitting challenges of
restoring and enhancing the T8 drainage versus installing a bypass pipe.
Water Supply and Distribution
In 2010,the City of Tigard updated its Water System Master Plan (WSMP),which addresses water
supply capacity needs and guides water system infrastructure improvements in the Tigard Water Service
Area. Since the adoption of the WSMP and its update in 2010, the city undertook the community
planning process for River Terrace and developed the River Terrace Water System Master Plan
Addendum to address the supply and distribution of water to this area.
There are three water pressure zones in River Terrace: 410,550,and 713.A water pressure zone is a
geographic area that is determined by elevation. Pressure is maintained by gravity pulling water from
storage facilities which are located at high elevations in each zone.
Page 7-4 City of Tigard
RIVER TERRACE COMMUNITY PLAN
Two of the three pressure zones in the River Terrace area can be easily and effectively served by the
extension of existing distribution and transmission lines. In order to serve the remaining pressure zone
(River Terrace 550 Zone),the city will need to
Figure 7-2:Water Pressure Zones provide more water storage in addition to new
transmission lines.The recommendation is to
construct a three million gallon storage reservoir
on the city-owned Cach property,which was
purchased for this purpose to meet existing
storage deficiencies in the area.

Sanitary Sewer Management
In 2010,the City of Tigard updated its Sanitary Sewer Master Plan (SSMP),which evaluates wastewater
flows based on land uses,establishes gravity sewer pipe sizes,and serves as a guide for all capital sewer
projects within the city. Since the adoption of the SSMP and its update in 2010,the city undertook the
community planning process for River Terrace and developed the River Terrace Sanitary Sewer Master
Plan Addendum to address sanitary sewer management in this area.

2. Continue to coordinate with CWS and the City of Beaverton on sanitary sewer projects that
serve River Terrace.
Community Facilities
River Terrace,once fully developed,will result in the addition of approximately 6,400 new residents to
the City of Tigard.These new residents will not arrive all at once. However,it is important for the city,
and the various service providers in the area that serve city residents,to anticipate and plan for the
social,educational and safety needs of these new residents in the same way that it does for existing
residents.
To that end,various service providers were engaged during the River Terrace community planning
process in order that they might help identify any community service provision issues,contribute to the
overall vision for River Terrace as a community of great neighborhoods,and understand how and when
development is likely to occur in River Terrace so that their agencies could plan accordingly. The
following service providers participated in the River Terrace Community planning process:
■ Tigard-Tualatin School District
■ Beaverton School District
■ Tualatin Valley Fire and Rescue ('I'VFR)
■ Tigard Police Department

require coordination with TVFR to ensure that fire access standards are met.
RECOMMENDED ACTION MEASURES
1. Continue to coordinate with both school districts to facilitate the development of safe routes
to future school sites in the area consistent with the city's Strategic Plan for walkability.
2. Continue to coordinate with TVFR to ensure that fire access standards are met during the
design and construction of key elements of the River Terrace transportation system,such as
the River Terrace Boulevard and any roundabouts.
Solid Waste Disposal
River'Terrace will be served by one of two solid waste haulers,namely Pride Disposal Company or
Waste Management Incorporated.These two haulers serve the entire city,and the addition of River
Terrace will not require a revision to the city's existing franchise agreement.
Additionally,River Terrace is within Metro's Regional Solid Waste Management Plan area,a 10-year
framework plan that coordinates solid waste and recycling in the Portland metropolitan area. Metro's
solid waste system is an organized network that includes solid waste collection,transportation,recycling
and processing.The nearest solid waste disposal facility to River Terrace is the Hillsboro Landfill,
located at 3205 SE Minter Bridge Road in Hillsboro.This solid waste disposal site serves the
communities of Aloha,Beaverton,Cornelius,Forest Grove,Gaston,Hillsboro,North Plains,Portland,
Sherwood,Tigard and unincorporated Washington County.
KEY FINDINGS
w River Terrace will be served by one of the city's existing solid waste haulers through an
existing franchise agreement.
w River Terrace will be able to utilize the existing solid waste disposal site in Hillsboro due to
its location within Metro's Regional Solid Waste Management Plan area.

RIVER TERRACE COMMUNITY PLAN
Goal 12: Transportation
As discussed in the previous section on Public Facilities,one of the principal goals of the River Terrace
Community Plan and the River Terrace Funding Strategy is to provide a framework for urban
development through the timely,orderly and efficient provision of public facilities in River Terrace.
Planning for the provision of transportation-related public facilities in this manner furthers the city's
goal of facilitating development in River Terrace and developing an efficient and balanced multi-modal
transportation system. It also meets Metro Functional Plan Title 11 and Statewide Planning Goal 12
requirements for ensuring that areas like River Terrace,which have been brought into the Urban
Growth Boundary(UGB) for urban development purposes,are efficiently urbanized and developed as
complete communities.
A Transportation System Plan (TSP) Addendum was created to address transportation-related public
facility needs in River Terrace.The River Terrace TSP Addendum appends the existing City of Tigard
TSP,which was updated in 2010. Since the city's adopted TSP already included household and vehicle
trip projections for River Terrace,the River Terrace TSP Addendum is assumed to comply with the
state's Transportation Planning Rule.Additionally,it was prepared to be consistent with the Portland
Metro Regional Transportation Plan.
The city's adopted TSP links expected growth with transportation needs and sets the policy framework
for the city's transportation system. It serves as a long-range guide for transportation investments by
incorporating the vision of the community into an equitable and efficient transportation system that
balances the needs of pedestrians,cyclists,drivers,transit users and freight carriers.
To that end,the River Terrace TSP Addendum envisions a Figure 8-1:River Terrace Boulevard
network of multi-modal streets that connects residents to
trails,schools,parks and services. One that conforms to the scho 5 Ferry Rd
rolling topography,builds upon and connects to existing legend
streets in the area,and effectively balances safety,comfort Existing Arterial
and mobility. More detailed information can be found on River Terrace Blvd.
Map 14 at the end of this document. Key elements' of the River Terrace Trail
addendum include: River Terrace
Boundary
■ signalized intersections where new or existing
Collector streets connect to Roy Rogers Road and
Scholls Ferry Road to safely accommodate drivers,
cyclists and pedestrians; g
■ connections to existing streets in adjacent Bull
Mountain neighborhoods to the east to improve street
connectivity in the area;
■ street and intersection design guidance for key streets
to control speeds,discourage cut-through traffic, Beef Bend Rd.
'Not all roads or intersections in the planning area are under the jurisdiction of the city.Any recommended improvement
to a road or intersection not under the jurisdiction of the city must be coordinated with and approved by the applicable
road authority.Specific recommendations are included here and in the River Terrace TSP Addendum to establish the
community's vision and the city's intention to work toward implementing that vision.Future and more detailed analysis
will determine whether specific signal or intersection improvements will be warranted or technically feasible.
City of Tigard Page 8-1
RIVER TERRACE COMMUNITY PLAN
increase travel options,enhance neighborhood livability and define and unify the area;and,
■ an innovative design concept for a signature street dubbed the"River Terrace Boulevard" that
incorporates the River Terrace Trail. See Figure 8-1 above for its location relative to other streets
in the area.
Existing major streets in and around River Terrace include Scholls Ferry Road to the north,Roy Rogers
Road to the west and Beef Bend Road to the south.'These streets serve an important regional through-
travel function and will benefit new residents by connecting them to regional destinations. Since
pedestrians and cyclists are often discouraged from using or crossing such streets due to high vehicle
speeds,high vehicle volumes and wide and/or infrequent road crossings,the River Terrace TSP
Addendum makes a number of recommendations that strive to balance the different and sometimes
competing needs of drivers,pedestrians and cyclists.
The River Terrace TSP Addendum recommends safe and appropriate bicycle and pedestrian facilities
along the whole length of Roy Rogers Road when it is widened to its full planned width,including a
buffered bike lane or cycle track to ensure the highest level of protection for cyclists. It also
recommends three traffic signals along Roy Rogers Road,equally spaced between Scholls Ferry Road
and Beef Bend Road,and a single traffic signal on Scholls Ferry Road,between Roy Rogers Road and
Barrows Road.'Traffic signals at intersections facilitate safe and comfortable pedestrian and bicycle
crossings. They also raise concerns about impacts to peak hour traffic flow and driver safety.These
concerns can be mitigated in a number of ways,such as with signal timing or through intersection
design.
The recommended signals will help vehicles cross and turn safely onto Roy Rogers Road and Scholls
Ferry Road.They will also provide pedestrians and cyclists with safe and convenient street crossings to
access:
■ the future River Terrace grade school to the south;
• the future South Cooper Mountain high school at the northwest corner of Scholls Ferry Road
and Roy Rogers Road;
■ several future trails to the north and south;
• future neighborhoods on both sides of Roy Rogers Road;and,
• the future neighborhood commercial center east of Roy Rogers Road.
In addition to connecting to existing major streets,the River Terrace TSP Addendum proposes
connections to existing local streets located to the east of River Terrace in existing Bull Mountain
neighborhoods.These connections are consistent with the city's existing transportation findings and
policies on connectivity for reducing trip length,4 providing an efficient transportation network,5 and
maximizing the investment in the existing transportation system.6 In the context of River Terrace,these
street connections are specifically meant to provide:
■ local and emergency vehicle access within and between new and existing neighborhoods;
2 All of these streets are under Washington County's jurisdiction.Any recommended improvements must be coordinated
with and approved by Washington County.
3 All traffic signals and intersection improvements must meet signal warrants and operational standards.
Tigard Comprehensive Plan Policy 12.2.3
s Tigard Comprehensive Plan Policy 12.3.5
e Tigard Comprehensive Plan Goal 12 Key Finding
Page 8-2 City of Tigard
RIVER TERRACE COMMUNITY PLAN
■ vehicle travel options that appropriately disperse traffic and preserve capacity on regional routes;
and,
■ safe,comfortable and convenient travel options for pedestrians and cyclists.
Local street connections will benefit both new and existing residents.They will also impact existing
neighborhoods by introducing additional traffic onto existing streets. Existing Bull Mountain residents
are particularly concerned that some street connections may also encourage cut-through traffic and/or
speeding.
The River Terrace TSP Addendum addresses these concerns and mitigates for these traffic impacts in a
variety of ways. Examples include recommendations to install a signal on Scholls Ferry Road and
connect Luke Lane via a circuitous route.A signal would provide drivers with a direct and efficient
route out of River Terrace,thereby reducing the need for out-of-direction travel through existing Bull
Mountain neighborhoods.A circuitous connection to Luke Lane would preserve its function as a local
street and minimize its attraction as a cut-through route.Traffic calming design treatments are also
recommended for the 161 Avenue and Lorenzo Lane extensions.Additionally,the city is committed to
working with existing Bull Mountain residents and Washington County staff to implement traffic
calming measures along Roshak Road to mitigate the impacts of existing traffic and the addition of new
traffic from River Terrace.
The River Terrace TSP Addendum also envisions a comprehensive trail system'for pedestrians and
cyclists that links the many existing natural resource areas,proposed parks, future schools and services,
and other planned and proposed regional trails in the area.This trail system is consistent with the River
Terrace Park System Master Plan Addendum,the city's Strategic Plan for walkability,and the Metro
Regional Trail and Greenways Plan.The city has a unique opportunity in River Terrace to provide trails
consistent with its adopted level of service standard due to the fact that,unlike the majority of the city,
River Terrace is largely undeveloped. However,implementing the vision for trails in River Terrace will
not be without its challenges,the main one being the preservation and acquisition of contiguous land
for future trail development along the recommended trail alignments.A more detailed discussion of the
ways in which the city could overcome these challenges is included in the section on Parks.
The innovative design concept for the River Terrace Boulevard,which is the main north-south
Collector Street in River Terrace,utilizes trail co-location as a street design element and a trail
implementation strategy.The River Terrace Trail travels from Scholls Ferry Road in the north to 150'`
Avenue in the southeast and is co-located with the boulevard for approximately 1.5 miles of its 2.25-
mile length.This trail was planned,in part,to complement Metro's Westside Trail,as it provides a less
steep travel option around Bull Mountain.The River Terrace Trail is a designated regional trail in the
2014 Metro Regional Transportation Plan and so is included in the River Terrace TSP Addendum as a
transportation facility for funding purposes.
In addition to its seamless incorporation of the trail,River Terrace Boulevard is unique in other ways.
Key design elements include a wide landscaped median and sidewalk bulbouts that are sizeable enough
to support large trees,on-street parking to calm traffic,and design standards for street-facing facades
and yards to ensure a high-quality and safe public realm. In combination,these elements are meant to
define the boulevard as the area's signature street and to effectively balance mobility with safety and
comfort for all modes of travel. See Figure 8-2 below for more detail.
7 Trail alignments and locations are illustrative. Trail alignments and locations are subject to change based on
development review,final design, engineering,permitting, connectivity and availability of land and funding. Final trail
alignments and locations to be determined at the time of city acquisition or in conjunction with development review.
City of Tigard Page 8-3
RIVER TERRACE COMMUNITY PLAN
In general,it is expected that both zoning and design flexibility will be needed to implement the River
Terrace Boulevard design concept. Zoning flexibility,with respect to housing types,will be needed to
support the vision of having homes front the street,and design flexibility will be needed along the
boulevard's entire length to accommodate topography, stream crossings,intersection treatments and a
wide range of land uses.On-street parking and the westernmost sidewalk, for example,may not always
be feasible or necessary in all locations. It may even be desirable to allow exceptions to the city's block
length standards in order to reduce the number of trail-side street crossings,thereby creating a more
continuous trail experience.

KEY FINDINGS
w The River Terrace TSP Addendum and,by extension,the River Terrace Community Plan
support the city's adopted transportation goals and policies. No new goals or policies are needed
to implement the transportation recommendations for River Terrace.
w The River Terrace TSP Addendum and the River Terrace Funding Strategy contribute to
meeting the city's PFP requirement under Statewide Planning Goal 11. Collectively,these
documents contain all required PFP elements,namely:
o An inventory of existing infrastructure
o A list of needed public facility projects
o A list of planning level cost estimates for each project
Page 8-4 City of Tigard
RIVER TERRACE COMMUNITY PLAN
o Maps and/or written descriptions of each project
o Public facility service provider information
o An estimate of when each project will be needed
o A funding strategy for each project
w The River Terrace TSP Addendum recommends several multi-modal street and intersection
improvements in and around the River Terrace area. Key elements of the addendum include:
signalized intersections where new or existing Collector streets connect to Roy Rogers Road and
Scholls Ferry Road to accommodate drivers,cyclists and pedestrians;connections to existing
streets in adjacent Bull Mountain neighborhoods to the east to improve street connectivity in the
area;street and intersection design guidance for key streets to control speeds,discourage cut-
through traffic,increase travel options,enhance neighborhood livability and define and unify the
area;and,an innovative design concept for a signature street dubbed the"River Terrace
Boulevard" that incorporates the River Terrace Trail.
w The River Terrace TSP Addendum envisions a street extension outside River Terrace and the
UGB for street connectivity and stormwater conveyance purposes.Transportation facilities
located outside the UGB must address land use regulations from the Washington County
Community Development Code Sections 340-4.1 and 430-105.3 through 430-105.7;Oregon
Revised Statute 215.275;and Oregon Administrative Rule 660-012-0070.
w Expansion of the UGB to include the Urban Reserve Area south of River Terrace and north of
Beef Bend Road would provide more opportunities for connectivity and stormwater
management in River Terrace than currently exist.
w Implementation of the design concept for River Terrace Boulevard will require zoning and
design flexibility and corresponding amendments to the Community Development Code and the
Public Improvement Design Standards.
w Funding and construction of River Terrace Boulevard will require a concerted and coordinated
effort between the city,the development community,and other partner agencies.
w River Terrace will connect to and utilize existing Washington County and Oregon Department
of Transportation(ODOT) facilities.The River Terrace TSP Addendum recommends
improvements to these facilities to serve River Terrace and the region.
ft River Terrace will impact existing Bull Mountain neighborhoods by connecting to and utilizing
existing streets.The River Terrace TSP Addendum mitigates these impacts in several ways.
RECOMMENDED ACTION MEASURES
1. Adopt the necessary elements of the River Terrace TSP Addendum and the River Terrace
Funding Strategy into the Comprehensive Plan to meet the city's PFP requirement under
Statewide Planning Goal 11 when all elements of the citywide PFP have been developed.
2. Work with Metro to add the recommended system improvements in the River Terrace TSP
Addendum that are on the regional network to the list of Financially Constrained Regional
Transportation Plan projects.
3. Work with Metro to bring the Urban Reserve Area south of River Terrace and north of Beef
Bend Road into the UGB and/or work with DLCD,Washington County,and other affected
City of Tigard Page 8-5

agencies to discuss the possibility of obtaining the necessary approvals to extend 161"Ave
outside the UGB to facilitate street connectivity and stormwater conveyance.
4. Amend the Community Development Code and the Public Improvement Design Standards
to allow for needed zoning and design flexibility along the entire length of River Terrace
Boulevard while staying true to the design concept.
5. Work with the development community and other potential partners to fund River Terrace
Boulevard per the recommendations in the River Terrace Funding Strategy.
6. Continue to work with Washington County and ODOT on a cost sharing and
implementation strategy for the recommended county and state highway facility
improvements identified in the River Terrace TSP Addendum,particularly with regard to the
widening of Roy Rogers Road,the installation of signals on Roy Rogers Road and Scholls
Ferry Road,and intersection improvements along Highway 99W.
7. Continue to work with Bull Mountain residents and Washington County staff to implement
traffic calming measures along Roshak Road to mitigate the impacts of existing traffic and
the addition of new traffic from River Terrace.
8. Look for opportunities to create pedestrian and bicycle connections within River Terrace
and between River Terrace and existing adjacent neighborhoods along existing stream
corridors and within future regional stormwater facilities consistent with the city's natural
resource protection goals,the River Terrace Stormwater Master Plan,and the city's Strategic
Plan for walkability.

Goal 14: Urbanization
The River Terrace Community Plan,River Terrace Funding Strategy and various River Terrace
infrastructure master plans collectively provide for the orderly and efficient transition of River Terrace
from rural to urban land use.These plans are consistent with Metro Functional Plan Titles 11 and 14
and Statewide Planning Goal 14 for accommodating future population growth,ensuring the efficient use
of land and creating livable communities.They also further the city's goal of facilitating development in
River Terrace in a way that results in high-quality development,natural resource protection and the
provision of essential public facilities and services in a coordinated,logical and fiscally sound manner.

outside UGB. the city also amended the policies in the Tigard
Comprehensive Plan under Goal 14.3.These
amendments describe the UGB expansion
related to River Terrace;designate the city as the urban service provider for River Terrace;and,state the
city's responsibility to prepare and adopt a River Terrace Community Plan and associated urban zoning
designations, five infrastructure master plans and an infrastructure funding strategy to facilitate urban
development.
The urban zoning district designations that will apply in River Terrace are described in the section on
Land Use.The five infrastructure master plans are described more fully in the Parks,Public Facilities
and Transportation sections and are listed below for reference:
■ River Terrace Water System Master Plan Addendum
• River Terrace Sanitary Sewer Master Plan Addendum
City of Tigard Page 9-1
RIVER TERRACE COMMUNITY PLAN
■ River Terrace Stormwater Master Plan
■ River Terrace Park System Master Plan Addendum
• River Terrace Transportation System Plan Addendum
Pursuant to Metro Functional Plan Title 11 for Urban Reserve Areas,the River Terrace master plans for
water and sewer take the future public facility needs in the Urban Reserve Areas adjacent to River
Terrace into consideration.This level of planning and coordination is intended to prevent costly and
disruptive upsizing and/or relocation of public facilities in the future.
Consistent with the intent and purpose of the UGB,the River Terrace master plans recommend urban-
level public facility improvements within the UGB wherever possible. However,there are two instances
where public facilities are envisioned outside the UGB. The River Terrace Stormwater Master Plan
recommends stormwater conveyance facilities outside the UGB due to soil,bedrock and slope
conditions,and the River Terrace Transportation System Plan Addendum envisions a street extension
outside the UGB for connectivity purposes. Expansion of the UGB to include the Urban Reserve Area
south of River Terrace and north of Beef Bend Road would provide more opportunities for
connectivity and stormwater management in River Terrace than currently exist. Figure 9-1 on the
previous page shows the location of these facilities in relation to River Terrace and the UGB.
Consistent with city policies regarding annexation and the provision of urban level services to properties
within the Tigard city limits,properties in River Terrace must annex to the city in order to receive the
urban zoning district designations described in the Land Use section of the Community Plan.All
properties in River Terrace voluntarily annexed to the city in 2011 and 2013. Consequently,all
properties in River Terrace will receive the zoning district designations described herein upon adoption
of the River Terrace Zoning Districts Map.
KEY FINDINGS
w The River Terrace Community Plan,River Terrace Funding Strategy and various River
Terrace infrastructure master plans collectively implement the goals and policies of the
Tigard Comprehensive Plan and the requirements of Metro Functional Plan Titles 11 and 14
regarding urbanization.
w The Introduction and Key Findings of Chapter 14 of the Tigard Comprehensive Plan do not
reflect the River Terrace policy amendments that were adopted in 2012 under Goal 14.3.
w Urban development in River Terrace cannot occur until the Comprehensive Plan and urban
zoning district designations described in the Land Use section of the Community Plan are
adopted.
Urban development in River Terrace cannot occur until adequate public facilities and
services are in place.These facilities and services are more fully described in the Parks,
Public Facilities and Transportation sections of the Community Plan and in the five
infrastructure master plans developed for River Terrace.
w Public facilities are envisioned outside the UGB for street connectivity and stormwater
conveyance purposes to support development in River Terrace.

LOCATION: River Terrace Plan Area
APPLICABLE REVIEW CRITERIA:
Community Development Code Chapters 18.380.020 and 18.390.060.G;
Comprehensive Plan Goals 1, 2, 5, 6,7, 8, 10, 11, 12, 13 and 14;Statewide
Planning Goals 1, 2, 5, 6, 7, 8, 10, 11, 12, 13 and 14; and Metro's Urban
Growth Management Functional Plan Title 1, 3, 11, 12, 13 and 14.
SECTION II. PLANNING COMMISSION RECOMMENDATION
The Planning Commission recommends that the City Council adopt by ordinance a Comprehensive
Plan Amendment that adopts the River Terrace Community Plan, related changes to the
Comprehensive Plan Designations Map and Natural Resources Maps, and the River Terrace
Addendum to the Transportation System Plan,as deternuned through the public hearing process.
SECTION III. BACKGROUND INFORMATION
Project History
Most of the land in River Terrace, approximately 440 acres, was added to the UGB in 2002, at
which time it was identified as Areas 63 and 64. Washington County completed the concept plan
for Areas 63 and 64 in 2010. This plan is entitled the West Bull Mountain Concept Plan (WBMCP)
STAFF REPORT TO THE CITY COUNCIL
CPA 2014-00001 River Terrace Community Plan PAGE 1 OF 32
and included Areas 63 and 64 and a rural subarea to the south of both areas that extended to Beef
Bend Road. This rural subarea was included in the concept planning process to facilitate logical
street connections and urban service extensions since Areas 63 and 64 were not contiguous to one
another.
Approximately 50 acres of this rural subarea was added to the UGB in 2011, at which time it was
identified as Roy Rogers West (sometimes referred to as Area 4). Collectively these three areas, i.e.
Area 63, Area 64, and Roy Rogers West, comprise the River Terrace planning area. Unlike the
WBMCP, the River Terrace Community Plan (RTCP) does not include the remainder of the rural
subarea (which is now an Urban Reserve Area) to the south of River Terrace. The entire 490-acre
area that makes up River Terrace was annexed to the City in two batches. The first annexation
petition was approved in 2011,and the second was approved in 2013.
In 2012, Washington County and the City of Tigard entered into an intergovernmental agreement
(IGA) whereby the County assigned and the City agreed to accept responsibility for preparing a
community plan based on the concept planning efforts completed by the County in 2010. Pursuant
to the IGA and in compliance with Metro Functional Plan Titles 11 and 14, the City agreed to
"refine the County's West Bull Mountain Concept Plan (WBMCP) and provide a detailed land use,
public infrastructure, governance, and financial planning framework for urban development of the
concept planned area." In turn, the County agreed to support the City's efforts to complete the
RTCP.
Proposal Description
A Comprehensive Plan Amendment (CPA) to adopt the River Terrace Community Plan,
Comprehensive Plan Designations Map, Natural Resource Maps, and a River Terrace Addendum
to the city's Transportation System Plan.
River Terrace Communiety Plan
The River Terrace Community Plan (RTCP) is a long range planning document that supplements
the Tigard Comprehensive Plan. It is designed to guide development and investment in River
Terrace over the next several decades as it transitions from rural to urban land use to accommodate
needed housing in the region. It is the result of many years of analysis and visioning by the
community, City of Tigard leadership and staff, Washington County leadership and staff, and
numerous partner agencies.
The city is required to prepare and adopt comprehensive plan provisions, public facility plans and
land use regulations to meet the requirements of the specific Metro ordinances that added River
Terrace to the Urban Growth Boundary UGB). The city is also required by Metro Functional Plan
Titles 11 and 14 and Statewide Planning Goals 11 and 14 to ensure that areas brought into the
UGB are efficiently urbanized and meet long-term population and employment needs. The
completion and adoption of the River Terrace Community Plan contributes to meeting all city,
state,and Metro requirements for land use and public facility planning.
STAFF REPORT TO THE CITY COUNCIL
CPA 201400001 River Terrace Community Plan PAGE 2 OF 32
The city will need to take additional actions to implement the RTCP. Identified implementation
actions include,but are not limited to, the following:
• Adoption of the River Terrace Zoning Districts Map
• Development and adoption of River Terrace code amendments
• Development of a new stormwater modeling tool and design standards
• Development and adoption of new fees consistent with recommendations in the River
Terrace Funding Strategy
Some of these actions are being timed and coordinated with other actions. The adoption of the
River Terrace Zoning Districts Map, for example,is being delayed in order to more closely align its
adoption with the completion of the River Terrace Code Amendments, which are still under
development. Some, but not all,of these actions will require City Council review and approval and
will be presented for Council's consideration at future dates.
Updates to Tigard Comprehensive Plan Designations and Natural Resource Mates
In order to apply the city's land use regulations in River Terrace, several maps must be updated.
This includes the city's:
• Comprehensive Plan Designations - This map updates the city's existing Comprehensive
Plan designations for River Terrace. The city initially adopted Comprehensive Plan
designations for River Terrace in 2012 based on the land use recommendations contained
in the West Bull Mountain Concept Plan (WBMCP). During the River Terrace community
planning process, refinements were made to the recommended WBMCP land uses in order
to support a better range and mix of zoning districts and, by extension, housing types.
These refinements were vetted by stakeholders,are consistent with the density assumptions
and guidelines in the WBMCP, and meet Metro's required residential densities for each
area.
• Natural Resource Maps - These maps update existing city maps that regulate tree groves,
habitat conservation areas,and wetland and riparian areas to include the River Terrace area.
Detailed inventory work was required to update each map. This work was completed
during the WBMCP and RTCP planning processes.
An advisory group made up of eighteen members was formed to provide advice and guidance to
the project team during the Community Plan planning process. Known as the Stakeholder Working
Group, they voted on August 22, 2013 to move the Comprehensive Plan Designations forward for
adoption. Since the natural resource maps are very technical in nature and were developed using
existing policies and standards, the Stakeholder Working Group was not asked to recommend them
for adoption. They were, however, given multiple opportunities to review and understand their
implications.
STAFF REPORT TO THE CITY COUNCIL
CPA 201400001 River Terrace Community Plan PAGE 3 OF 32
River Terrace Transportation Saem Plan Addendum
As part of State and Metro requirements for public facility planning, the city must adopt a local
transportation system plan that provides for a multi-modal system of streets, trails, and sidewalks
within River Terrace with connections to adjacent urban areas and the regional transportation
system. This plan is being adopted as an addendum to the city's Transportation System Plan (TSP).
Because TSP amendments require a Type IV legislative process, this is the only River Terrace
master plan that Council needs to adopt by Ordinance.
The TSP links expected growth with transportation needs and sets the policy framework for the
city's transportation system. The proposed TSP Addendum looks to accommodate the
transportation needs anticipated in River Terrace in addition to contributing to the city's broader
goal of completing the RTCP.
The Stakeholder Working Group voted to cautiously move the River Terrace TSP Addendum
forward for adoption on June 9, 2014. Their recommendation for caution primarily revolved
around project costs and their concern that costs may be too high for the market to bear. Council
was briefed on these issues and the TSP Addendum in general at a workshop meeting on June 17,
2014.
Planning Commission Recommendation
On November 17, 2014 the Tigard Planning Commission held a public hearing to consider the
proposal and make a recommendation to Council. As discussed in greater detail in Section VIII of
this report and in the minutes of the hearing, public testimony was received and considered by the
Planning Commission as part of their deliberations. At the conclusion of their deliberations, the
Planning Commission made a unanimous recommendation to the City Council that all four
elements of the proposal be approved and adopted as presented to the Commission.

community of great neighborhoods that includes housing,neighborhood-
scale commercial businesses, schools,parks and recreational opportunities.
Community Plan Chapter 1: Introduction and Background describes that a
funding strategy was developed concurrently with the Community Plan
pursuant to state and regional requirements. The River Terrace Funding
Strategy will be presented to Council for adoption by separate action during
the same meeting that the Community Plan is considered for adoption.
Additionally,a Citywide Infrastructure Financing Project is currently
underway and is expected to result in updates to the city's existing utility fees
and System Development Charges,some of which are expected to be specific
to River Terrace per the recommendations contained in the River Terrace
Funding Strategy.
CONCLUSION: Based on the above findings, Tigard Comprehensive Plan Goal 2.1 Policies
G and 10 are met.
Policy 7 The City's regulatory land use maps and development code shall
implement the Comprehensive Plan by providing for needed urban land
uses including:
A. Residential;
B. Commercial and office employment including business parks;
C. Mixed use;
D. Industrial;
E. Overlay districts where natural resource protections or special
planning and regulatory tools are warranted; and
F. Public services
Policy 22 The City shall identify, designate, and protect natural resources as part
of its land use program.
FINDING: This CPA,specifically the River Terrace Community Plan and
Comprehensive Plan designations,includes primarily residential
Comprehensive Plan designations that provide a mix of residential densities.
This allows for a variety of housing types that meet a wide range of housing
needs. Higher residential densities are planned near commercial and
institutional uses and along major corridors. Lower residential densities are
planned in areas with steep slopes and along the area's eastern edge to
provide a buffer between existing lower density neighborhoods and future
higher density neighborhoods. The commercial area is sized and zoned to
provide neighborhood-scale commercial goods and services.The co-location
of land uses (e.g. parks and trails),public facilities (e.g. stormwater facilities
and pump stations),and natural resource areas is strongly encouraged to
maximize the efficient use of land and to create opportunities for community
amenities.
The River Terrace Community Plan addresses the City's Goal S Natural
Resources for River Terrace. In addition,the city's Natural Resource maps
STAFF REPORT TO THE CITY COUNCIL
CPA 201400001 River Terrace Community Plan PAGE 9 OF 32
are being updated for the River Terrace area to ensure that these areas are
protected. The city's existing protection programs for natural resources will
be extended to the newly mapped areas in River Terrace.
CONCLUSION: Based on the above findings, Tigard Comprehensive Plan Goal 2.1 Policies
7 and 22 are met.
Policy 8 The City shall require that appropriate public facilities are made
available,or committed, prior to development approval and are
constructed prior to, or concurrently with, development occupancy.
Policy 9 The City may, upon determining it is in the public interest, enter into
development agreements to phase the provision of required public
facilities and services and/or payment of impact fees and/or other
arrangements that assure the integrity of the infrastructure system and
public safety.
Policy 13 The City shall plan for future public facility expansion for those areas
within its Urban Planning Area that can realistically be expected to be
within the City limits during the planning period.
FINDING: River Terrace Community Plan Goal: 11 Public Facilities and Services
addresses public facility planning for River Terrace. The Comprehensive Plan
designations proposed for adoption determined the type, number and
location of residential dwelling units in River Terrace. This information was
used to help determine the size and location of needed public facilities and
services.
The Community Plan more fully describes future public facility expansion in
the sections on Parks,Public Facilities and Transportation and in the five
infrastructure master plans developed for River Terrace. The five
infrastructure master plans include: water, sewer, stormwater, transportation
and parks. Water, sewer and stormwater master plans have already been
adopted;while the transportation and parks master plans are proposed for
adoption with this CPA. The plans include a list of infrastructure
improvements necessary to accommodate the River Terrace area.
Updates to the city's adequate facility requirements will be included in the
upcoming River Terrace Code Amendments as part of Community Plan
implementation.
CONCLUSION: Based on the above findings, Tigard Comprehensive Plan Goal 2.1 Policies
8,9 and 13 are met.
Policy 15 In addition to other Comprehensive Plan goals and policies deemed
applicable, amendments to Tigard's Comprehensive Plan/Zone Map
shall be subject to the following specific criteria:
A. Transportation and other public facilities and services shall be
available, or committed to be made available, and of sufficient capacity
to serve the land uses allowed by the proposed map designation;
ti'I'.AIP R1{PURI"I'C�"I'klL CITA COUNCIL.
(TA 2014-00)0 1 River Terrace Community-Plan PAGE 1001-32
B. Development of land uses allowed by the new designation shall not
negatively affect existing or planned transportation or other public
facilities and services;
C.The new land use designation shall fulfill a proven community need
such as provision of needed commercial goods and services,
employment, housing, public and community services, etc. in the
particular location,versus other appropriately designated and
developable properties;
D. Demonstration that there is an inadequate amount of developable,
appropriately designated, land for the land uses that would be
allowed by the new designation;
E. Demonstration that land uses allowed in the proposed designation
could be developed in compliance with all applicable regulations and
the purposes of any overlay district would be fulfilled;
F. Land uses permitted by the proposed designation would be
compatible, or capable of being made compatible,with environmental
conditions and surrounding land uses; and
G. Demonstration that the amendment does not detract from the
viability of the City's natural systems.
FINDING: The proposed amendment to Tigard's Comprehensive Plan Map meets the
following specific criteria:
• Sufficient capacity: The Community Plan describes that updates to the
city's adequate facility requirements will be included in River Terrace
Code Amendments as part of Community Plan implementation.
• Not negatively affecting: The Community Plan more fully describes
future public facility expansion in the sections on Parks, Public
Facilities and Transportation and in the five infrastructure master
plans developed for River Terrace. The plans include a list of
infrastructure improvements necessary to accommodate development
in River Terrace.
• Fulfills a proven community need: Almost 97% of the land in River
Terrace is proposed for new housing. A citywide analysis of housing
needs and capacity in 2012 found that Tigard has an estimated need
for just over 6,500 new housing units over the next 20 years. Over
50% of the city's overall need (3,744 housing units) could be absorbed
by River Terrace development.
• Demonstration of inadequacy: A significant portion of the city's
estimated capacity for needed housing is assumed to come from River
Terrace.
• Demonstration of compliance: The River Terrace Community Plan
utilizes the city's existing Comprehensive Plan and zoning district
designations.
• Compatibility: Higher residential densities are planned near
commercial and institutional uses and along major transportation
corridors. Lover residential densities are planned in areas with steep
slopes and along the area's eastern edge to provide a buffer between
existing lower density neighborhoods and future higher density
neighborhoods.

CPA 2014-00001 River Terrace Community Plan P.\G F? 11 OF 32
• Viability of natural systems: The city's Natural Resource maps are
being updated for the River Terrace area to ensure that these areas
are protected. The city's exiting protection programs for natural
resources will be extended to the newly mapped areas in River
Terrace.
CONCLUSION: Based on the above findings, Tigard Comprehensive Plan Goal 2.1 Policy
15 is met.
Chapter 5: Natural Resources and Historic Areas
Goal S.1 Protect natural resources and the environmental and ecological functions they
provide and, to the extent feasible, restore natural resources to create naturally
functioning systems and high levels of biodiversity.
Policy 4 The City shall actively coordinate and consult with landowners, local
stakeholders, and governmental jurisdictions and agencies regarding
the inventory, protection, and restoration of natural resources.
Policy 10 The City shall complete a baseline inventory of significant natural
resources and update or improve it as necessary, such as at the time
of Comprehensive Plan Periodic Review, changes to Metro or State
programs,or to reflect changed conditions, circumstances, and
community values.
FINDING: This CPA amends the city's Natural Resource maps to include the River
Terrace plan area. The city will utilize the same natural resource protection
programs as the rest of the city. Implementation of these programs will occur
through the adoption of several inventories and maps that provide various
levels of natural resource assessment and protection as well as development
flexibility.
The River Terrace Community Plan addresses the city's Goal 5: Natural
Resources and speaks to the city's coordination and inventory of significant
natural resources in River Terrace.
• The Natural Resource maps proposed for adoption update existing
city maps that regulate tree groves, habitat conservation areas, and
wetland and riparian areas to include the River Terrace area. Detailed
inventory work was required to update each map,which was
completed as part of the West Bull Mountain and River Terrace
planning processes.
• The SWG,TAC, community, and outside agencies had an
opportunity to review each map. Since the Natural Resource maps are
very technical in nature and were developed using existing policies
and standards, the Stakeholder Working Group was not asked to
recommend them for adoption. They were,however,given multiple
opportunities to review and understand their implications.

The River Terrace Addendum to the Transportation System Plan includes the
following language on protection of natural resources:
• Street alignments and intersections should avoid and/or minimize
impacts to identified natural resource areas whenever possible.
CONCLUSION: Based on the above findings, Tigard Comprehensive Plan Goal 5.1 Policies
4 and 10 are met.
Chapter 6: Environmental Quality
Goal 6.1 Reduce air pollution and improve air quality in the community and region.
Policy 3 The City shall promote land use patterns,which reduce dependency
on the automobile, are compatible with existing neighborhoods, and
increase opportunities for walking, biking, and /or public transit.
Policy 6 The City shall encourage the maintenance and improvement of open
spaces, natural resources, and the City's tree canopy to sustain their
positive contribution to air quality.
FINDING: The River Terrace Community Plan and maps, and the Transportation
System Plan Addendum support the city's adopted environmental quality
goals and policies. Specifically:
• Land use patterns: The River Terrace Community Plan and
Comprehensive Plan designations will allow for more intense urban
land uses that reduce the dependency on the automobile and increase
opportunities for walking,biking,and public transit. The
Transportation System Plan Addendum identifies several multi-modal
street and intersection improvements in and around the River Terrace
area. The Walking and Biking Network,Figure 6 of the TSP
Addendum illustrates the potential active transportation network for
the River Terrace plan area. The emphasis of this network is on
connecting residents to existing and future trails,as defined in the
Metro Regional Trail and Greenways Plan, as well as key destinations
within and near the River Terrace Community Plan area, including the
neighborhood commercial area in the north and the future school in
the south.
• Open spaces, natural resources, and tree canopy: This CPA updates
the city's Natural Resource maps for the River Terrace area,including
the significant tree groves map. As discussed in Goal 8: Parks,
Recreation,Trails and Open Space of the Community Plan, 65 acres
of open space is proposed in River Terrace.
CONCLUSION: Based on the above findings, Tigard Comprehensive Plan Goal 6.1 Policies
3 and 6 are met.
Goal 6.2 Ensure land use activities protect and enhance the community's water
quality.
STAFF REPORT TO T[[F.ffn'COUNCII,
CPA 2014-00001 River Terrace Community Plan PAGE 13 OF 32
Policy 3 The City shall encourage the use of low impact development practices
that reduce stormwater impacts from new and existing development.
Policy 4 The City shall protect, restore, and enhance, to the extent practical, the
natural functions of stream corridors, trees, and water resources for
their positive contribution to water quality.
Policy 10 The City shall continue to facilitate the extension of the City's
wastewater system to neighborhoods without service within the Tigard
Urban Service Area, provided:
A. properties benefiting from the extension pay their fair share of the
cost; and
B. annexation occurs prior to any property receiving service.
FINDING: River Terrace Community Plan Goal 11: Public Facilities and Services
addresses planned infrastructure system improvements for stormwater and
wastewater in River Terrace:
• A Stormwater Master Plan was created to manage stormwater in the
River Terrace area. It recommends two water quality strategies: (1)
Low Impact Development Approaches (LIDA) at a variety of scales,
and (2) regional water quality facilities. The River Terrace Stormwater
Master Plan has already been adopted.
• A River Terrace Sanitary Sewer Master Plan addendum was
developed to address sanitary sewer management for the River
Terrace plan area. The River Terrace Sanitary Sewer Master Plan
Addendum has already been adopted.
In addition,the River Terrace Community Plan aims to protect natural
resources and preserve their aesthetic and environmental benefits. Natural
resource protection will also be achieved through the development of
effective stormwater management facilities that protect the community's
water supply and the health and function of stream corridors for habitat and
recreation. For example, the River Terrace Stormwater Master Plan contains
goals to restore and enhance vegetative corridors, protect water quality,
preserve existing hydrology, preserve existing mature vegetation, and more.
This CPA also updates the city's Natural Resource maps for the River Terrace
area in order to implement the city's current protection and incentive
programs to retain and protect the city's natural resources.
CONCLUSION: Based on the above findings, Tigard Comprehensive Plan Goal 6.2 Policies
3,4 and 10 are met.
Chapter 7: Hazards
Goal 7.1 Protect people and property from flood, landslide, earthquake, wildfire, and
severe weather hazards.
Policy 3 The City shall coordinate land use and public facility planning with
STAFF REPORT TO TI IE CIT'COUNCIL.
CPA 2011-00001 River Terrace Communiry Plan PAG 1: 14()F32
public safety providers (law enforcement, fire safety, and emergency
service providers) to ensure their capability to respond to hazard events.
FINDING: The city's public safety providers (law enforcement and Tualatin Valley Fire
and Rescue) served as members of the Technical Advisory Committee for this
project. The Community Plan and River Terrace Addendum to the
Transportation System Plan identify future connections needed to ensure
these providers are capable of responding to future hazard events. These
connections are intended to provide local and emergency vehicle access
within and between new and existing neighborhoods.
CONCLUSION: Based on the above findings, Tigard Comprehensive Plan Goal 7.1 Policy 3
is met.
Chapter 8: Parks, Recreation,Trails and Open Space
Goal 8.1 Provide a wide variety of high quality park and open spaces for all residents,
including both:
A. developed areas with facilities for active recreation;and
B. undeveloped areas for nature-oriented recreation and the
protection and enhancement of valuable natural resources within the
parks and open space system.
Policy 3 The City shall seek to achieve or exceed the ideal park service level
standard of 11.0 acres of parkland per thousand population.
Policy 4 The City shall endeavor to develop neighborhood parks [or
neighborhood park facilities within other parks, such as a linear park]
located within a half mile of every resident to provide access to active
and passive recreation opportunities for residents of all ages.
Policy 19 The City shall seek to establish and manage a fully functional urban
forest.
FINDING: River Terrace Community Plan Goal 8: Parks, Recreation,Trails,and Open
Space supports the city's adopted park goals and policies. No new goals or
policies are needed to implement the park recommendations for River
Terrace.
The city's adopted Level of service (LOS) standards for parks were used in
planning for the River Terrace. Community Plan Table 5-2 describes River
Terrace park standards, needs, and recommendations. Overall, the city is
proposing to exceed the city's (updated) core standard by over 37 acres. The
full range of park types is envisioned in River Terrace to provide access for
both active and passive recreation. In lieu of identifying specific park
locations,parks are conceptually located within service areas to show where
community and neighborhood parks would be needed to meet LOS standards
and achieve the goal of having an equitable distribution of parks in the area.

Additionally, adoption of the proposed River Terrace Community Plan and
Significant Tree Groves map will extend the city's urban forestry program to
River Terrace. The River Terrace area has nine significant tree grove sites
totaling 61 acres.
CONCLUSION: Based on the above findings, Tigard Comprehensive Plan Goal 8.1 Policies
3,4 and 19 are met.
Goal 8.2 Create a Citywide network of interconnected on-and off-road pedestrian
and bicycle trails.
Policy 1 The City shall create an interconnected regional and local system of
on- and off-road trails and paths that link together neighborhoods,
parks, open spaces,major urban activity centers, and regional
recreational opportunities utilizing both public property and easements
on private property.
FINDING: The River Terrace Community Plan addresses trails in two sections - Goal 8:
Parks,Recreation,Trails,and Open Space and Goal 12: Transportation. As
stated in the Community Plan, the River Terrace Transportation System Plan
Addendum envisions a comprehensive trail system for pedestrians and cyclists
that links the many existing natural resources areas,proposed parks, future
schools and services, and other planned regional trails in the area. The trail
system is consistent with the River Terrace Park System Master Plan
Addendum,the city's Strategic Plan for walkability,and the Metro Regional
Trails and Greenways Plan.
The River Terrace Community Plan shows trails more specifically located
than parks. The River Terrace Trail,whose design has been uniquely
integrated with the main North-South Collector Street known as River
Terrace Boulevard was planned,in part, to complement Metro's`Westside
Trail.
CONCLUSION: Based on the above findings, Tigard Comprehensive Plan Goal 8.2 Policy 1
is met.
Chapter 10: Housing
Goal 10.1 Provide opportunities for a variety of housing types at a range of price levels to
meet the diverse housing needs of current and future City residents.
Policy 1 The City shall adopt and maintain land use policies, codes, and
standards that provide opportunities to develop a variety of housing
types that meet the needs, preferences and financial capabilities of
Tigard's present and future residents.
Policy 2 The City's land use program shall be consistent with applicable state
and federal laws.
STAFF REPORT TO TI IE CITY COUNCIL.
CPA 201400001 River Terrace Community Plan PAG P 16()1;32
FINDING: The River Terrace Community Plan addresses the city's Goal 10: Housing for
River Terrace. The Community Plan supports the city's adopted housing
goals and policies. Almost 97% of the buildable land in River Terrace is
proposed for new housing.
River Terrace stakeholders prioritized a range of residential densities to
provide diverse housing types,a variety of housing choices, and integration
with existing adjacent Bull Mountain neighborhoods when designing the land
use framework for River Terrace. The proposed land uses meet state and
Metro requirements for density and the opportunity for attached housing.
The city's existing affordable housing program will apply to River Terrace.
Updates to the citywide program are expected in 2015.
CONCLUSION: Based on the above findings,Tigard Comprehensive Plan Goal 10.1 Policies
1 and 2 are met.
Goal 10.2 Maintain a high level of residential livability.
Policy 2 The City shall seek to provide multi-modal transportation
access from residential neighborhoods to transit stops, commercial
services, employment, and other activity centers.
Policy 5 The City shall encourage housing that supports sustainable
development patterns by promoting the efficient use of land,
conservation of natural resources, easy access to public transit and
other efficient modes of transportation, easy access to services and
parks, resource efficient design and construction, and the use of
renewable energy resources.
Policy 6 The City shall promote innovative and well-designed housing
development through application of planned developments and
community design standards for multi-family housing.
Policy 7 The City shall ensure that residential densities are appropriately related
to locational characteristics and site conditions such as the presence of
natural hazards and natural resources, availability of public facilities
and services, and existing land use patterns.
Policy 8 The City shall require measures to mitigate the adverse impacts from
differing, or more intense, land uses on residential living environments,
such as:
A. orderly transitions from one residential density to another;
B. protection of existing vegetation, natural resources and provision of
open space areas; and
C. installation of landscaping and effective buffering and screening.
FINDING: This CPA,through the River Terrace Community Plan and TSP Addendum,
proposes a multi-modal transportation system that is designed to connect
River Terrace to existing and future neighborhoods, services,parks, schools
STAFF REPORT TO TI IE CITY COUNCIL.
C11A 2014-00001 River Terrace Communinv Plan PAGE. 17 OI;32
and regional destinations through a hierarchy of streets and trails that provide
residents and visitors with convenient,safe and comfortable travel options.
This network of multi-modal streets conforms to the rolling topography,
builds upon and connects to existing streets in the area,and effectively
balances safety, comfort and mobility.
The Comprehensive Plan designations place higher residential densities near
commercial and institutional uses and along major corridors in order to
reduce dependency on vehicles. Lower residential densities are planned in
areas with steep slopes and along the area's eastern edge to provide a buffer
between existing lower density neighborhoods and future higher density
neighborhoods. The River Terrace Community plan encourages the co-
location of land uses (e.g. parks and trails), public facilities (e.g. stormwater
facilities and pump stations),and natural resource areas to maximize the
efficient use of land and to create opportunities for community amenities.
The city's current development code, specifically relating to buffering and
screening,will apply to the River Terrace area ensuring orderly transition of
residential densities. The city's current Planned Development regulations will
also apply to River Terrace. The city intends to propose changes to the
Planned development code to implement the River Terrace Community Plan.
These amendments are anticipated to be reviewed by Planning Commission
and Council in February 2015.
CONCLUSION: Based on the above findings,Tigard Comprehensive Plan Goal 10.2 Policies
2, 5, 6,7 and 8 are met.

the surrounding transportation system, as a result of the
recommended land uses, was evaluated through the year 2035. The
highest level of potential development for the River Terrace area
(2,587 households and 149 employees) was assumed. The result is a
set of transportation improvements and standards that updates the
Tigard TSP for the River Terrace area.
• The streets in River Terrace are designed to accommodate all modes
of travel for users of all ages and abilities where possible. They are
also designed to safely connect people to where they need to go,
providing residents and visitors with a number of travel choices to
their destinations. The streets are also envisioned to be more than just
places for automobile travel, recognizing that they are also where
people gather,walk, bike, access transit, and park their vehicles.
• Comprehensive Plan designations place higher residential densities
near commercial and institutional uses and along major corridors to
reduce dependency on vehicles.
• The TSP Addendum envisions a comprehensive trail system for
pedestrians and cyclists that links the many existing natural resource
areas, proposed parks, future schools and services, and other planned

improving arterial, collector, and local street connections.
Policy 4 The City shall design arterial routes,highway access, and adjacent land
uses in ways that facilitate the efficient movement of people,goods and
services.
Policy 6 The City shall develop and maintain an efficient arterial grid system
that provides access within the City, and serves through traffic in the
City.
FINDING: The River Terrace Community Plan acknowledges that the existing major
streets in and around River Terrace serve an important regional through-
travel function and will benefit new residents by connecting them to regional
destinations. The following streets in/near the River Terrace area are
classified as arterials: Beef Bend Road, Roy Rogers Road, and Scholls Ferry
Road. These streets serve the highest volume of motor vehicle traffic and are
expected to be utilized for longer distance regional trips.

facilities for all schools, parks, public facilities, and commercial areas.
FINDING: The River Terrace Community Plan envisions an interconnected network of
multi-modal streets,one that conforms to the rolling topography and builds
upon and connects with the existing streets in the area.The streets are
designed to accommodate all modes of travel for users of all ages and abilities
where possible. They are also designed to safely connect people to where they
need to go,providing residents and visitors with a number of travel choices to
their destinations. Connections to existing streets in adjacent Bull Mountain
neighborhoods to the east will improve street connectivity in the area.
Residents in the River Terrace area will be able to safely and efficiently travel
between destinations via any number of active transportation modes, such as
walking and biking. A system of sidewalks,bikeways,and trails will provide
access to key destinations such as parks,schools,and commercial areas—
improving the overall health and livability of the neighborhood.
River Terrace has many stream corridors and the potential for many
neighborhood and community parks. To best serve the needs of future

CONCLUSION: Based on the above findings, Tigard Comprehensive Plan Goal 14.2 Policy
6 is met.
APPLICABLE METRO REGULATIONS
Urban Growth Management Functional Plan
Title 1 Housing Capacity-The Regional Framework Plan calls for a
compact urban form and a "fair-share" approach to meeting regional
housing needs. It is the purpose of Title 1 to accomplish these
policies by requiring each city and county to maintain or increase its
housing capacity.
FINDING: Title 1 facilitates the efficient use of land within the Urban Growth Boundary
(UGB). This Title requires cities and counties to determine their capacity for
housing and adopt minimum density requirements. Title 1 also requires cities
and counties to report changes in capacity annually to Metro.
This amendment (CPA2014-00001) adopts the River Terrace Community
Plan,Comprehensive Plan designations,Natural Resource maps and a River
Terrace Transportation System Plan Addendum, which was completed
following the rules outlined in OAR 660, Division 7. The amendment sets
policy related to a 20-year supply of land and does not affect compliance
with Title 1.
Both Metro and Oregon Department of Land Conservation and
Development staff were provided the opportunity to review and comment
on all work leading up to the documents proposed for adoption as members
of the Technical Advisory Committee.
CONCLUSION: Based on the above findings, Metro's Urban Growth Management
Functional Plan Title 1 is met.
Title 3 Water Quality and Flood Management -To protect the beneficial water
uses and functions and values of resources within the Water Quality
and Flood Management Areas by limiting or mitigating the impact on
these areas from development activities and protecting life and property
from dangers associated with flooding.
FINDING: Metro's Title 3 requires that cities and counties adopt provisions that
protect life and property from flooding. The Natural Resource maps
proposed for adoption update existing city maps that regulate wedand and
riparian areas in the River Terrace area. Detailed inventory work was
required to update each map and was completed as part of the V'est Bull
Mountain and River Terrace planning processes. By adopting wetland and
riparian area maps for River Terrace and applying the city's Sensitive Lands
regulations to the area, the city is ensuring that River Terrace is in
compliance with Tide 3.

CONCLUSION: Based on the above findings, Metro's Urban Growth Management
Functional Plan Title 3 is met.
Title 11 Planning for New Urban Areas -The Regional Framework Plan calls
for long-range planning to ensure that areas brought into the UGB are
urbanized efficiently and become or contribute to mixed-use,walkable,
transit friendly communities. It is the purpose of Title 11 to guide such
long-range planning for urban reserves and areas added to the UGB. It
is also the purpose of Title 11 to provide interim protection for areas
added to the UGB until city or county amendments to land use
regulations to allow urbanization become applicable to the areas.
FINDING: This CPA meets the requirements of Metro Functional Plan Tide 11 for
ensuring that areas like River Terrace,which have been brought into the
Urban Growth Boundary (UGB) for urban development purposes,are
efficiently urbanized and developed as complete communities.
The River Terrace Community Plan,River Terrace Funding Strategy and
various River Terrace infrastructure master plans collectively provide for the
orderly and efficient transition of River Terrace from rural to urban land use.
These plans are consistent with Metro Functional Plan Titles 11 and 14 and
Statewide Planning Goal 14 for accommodating future population growth,
ensuring the efficient use of land and creating livable communities.They also
further the city's goal of facilitating development in River Terrace in a way
that results in high-quality development, natural resource protection and the
provision of essential public facilities and services in a coordinated,logical
and fiscally sound manner.
CONCLUSION: Based on the above findings, Metro's Urban Growth Management
Functional Plan Tide 11 is met.
Title 13 Nature in Neighborhoods -The purposes of this program are to (1)
conserve, protect, and restore a continuous ecologically viable
streamside corridor system, from the streams' headwaters to their
confluence with other streams and rivers, and with their floodplains in a
manner that is integrated with upland wildlife habitat and with the
surrounding urban landscape; and (2) to control and prevent water
pollution for the protection of the public health and safety, and to
maintain and improve water quality throughout the region.
FINDING: By expanding the city's natural resource program to include the River
Terrace area, the city is ensuring that River Terrace is in compliance with
Tide 13. River Terrace will utilize the same natural resource protection
programs as the rest of the city. Implementation of these programs will
occur through the adoption of several inventories and maps that provide
various levels of natural resource assessment and protection as well as
development flexibility.
STAFF REPORT TO THE CITY COUNCIL
CPA 2014-00001 River Terrace Community Plan p AG1,,2g O1;32
The River Terrace Community Plan addresses natural resources and speaks to
the city's coordination and inventory of significant natural resources in River
Terrace.
• The Natural Resource maps proposed for adoption update existing
city maps that regulate tree groves,habitat conservation areas,and
wetland and riparian areas to include the River Terrace area. Detailed
inventory work was required to update each map and completed as
part of the West Bull Mountain and River Terrace planning processes.
• The SWG,TAC,community,and outside agencies had an
opportunity to review each map. Since the natural resource maps are
very technical in nature and were developed using existing policies
and standards,the Stakeholder Working Group was not asked to
recommend them for adoption.They were,however,given multiple
opportunities to review and understand their implications.
CONCLUSION: Based on the above findings, Metro's Urban Growth Management
Functional Plan Title 13 is met.

Listed below are the main highlights from the oral and written comments received. The full
text of all comments can be found in the project file and Planning Commission minutes of
November 17, 2014.
• River Terrace Boulevard is too expensive and too wide:
o The design should be revised to reduce cost.
o Design flexibility is needed along the entire length to respond to land uses,
topography, and stream crossings.
o The concept design illustration should be removed to eliminate the
expectation that the full cross section will be built in all locations.
o Minimum and standard cross sections should be developed and shown
alongside the full cross section.
STAFF REPORT TO THE CITY COUNCIL
CPA 201400001 River Terrace Community Plan PAGE 31 OF 32
• The easternmost segment of the River Terrace Trail should be relocated or revised to
show a less specific alignment.
• The 161st Avenue extension project should be added to the near-term TSP project
list to facilitate access to the school property.
• The River Terrace Community Plan map should not show specific street alignments
or intersection treatments. In the alternative, it should include the same design
flexibility language as the Transportation System Plan (TSP) map.
The Planning Commission was presented copies of all written comments and heard all oral
testimony before rendering four unanimous motions to recommend approval of the River
Terrace Community Plan, updates to the Comprehensive Plan Designations Map and
Natural Resource Maps, and the River Terrace Addendum to the city's Transportation
System Plan (TSP). Commissioners supported keeping the River Terrace Boulevard
illustration and the River Terrace Trail alignment in the Community Plan and TSP in part
due to allowances for design and alignment flexibility already contained in the proposed
amendments. Commissioners also preferred to leave the 161st Avenue extension off the
TSP near-term project list, as it is atypical for a Neighborhood Route to be publicly funded.
Overall, the Planning Commission found the project to meet all relevant approval criteria
pertaining to the issues raised by the public.
SECTION IX. CONCLUSION
The proposed changes comply with the applicable Statewide Planning Goals, applicable regional,
state and federal regulations, the Tigard Comprehensive Plan, and applicable provisions of the
City's implementing ordinances.
Therefore, the Planning Commission recommends that the City Council adopt by ordinance a
Comprehensive Plan Amendment that adopts all of the following documents as determined
through the public hearing process:
1. River Terrace Community Plan and associated amendments to the Comprehensive
Plan Designations Map and Natural Resource Maps; and
2. River Terrace Addendum to the city's Transportation System Plan.
