In December 2018, the Metro Council voted to expand the urban growth boundary (UGB) to include the 1,232-acre Cooper Mountain area, enabling the city to embark on planning for the next 10 to 20 years of development on Cooper Mountain. The Cooper Mountain Community Plan project is a priority because the demand for housing in the region is strong and the adjacent South Cooper Mountain area is developing faster than expected. Cooper Mountain is an important future land supply for the city that is anticipated to bring at least 3,760 homes to the city over time, including a mix of single-family and multi-family homes.

The Cooper Mountain Community Plan will apply a lens of racial equity, consistent with the city’s Diversity, Equity and Inclusion Plan (2019), with a goal of providing great neighborhoods for all. Beaverton has hired Unite Oregon to lead multicultural engagement efforts for the Community Plan.
The planning process will be led by the city’s Community Development Department. The process will be advised by a community advisory committee (CAC), technical advisory committee (TAC), stakeholders, property owners, and local residents. Public engagement will begin during the early phases of the project, intensify during the Community Planning phase, and continue through plan adoption.
The process will be coordinated with and informed by related efforts, including the Cooper Mountain Utility Plan. The city will work closely with Washington County, Tualatin Hills Park and Recreation District, Clean Water Services, and other partner governments.
In addition, the city has hired a consultant team led by Angelo Planning Group to assist with the Community Plan. The team includes the following six consulting firms:
Working from the base of the 2014 Concept Plan prepared for Cooper Mountain, the Community Plan will include residential uses, parks, schools, open space and natural areas, and potentially local commercial services.
Metro conditions of approval for the UGB expansion require at least 3,760 housing units within the Cooper Mountain Community Plan area. The city also needs to comply with requirements for diverse housing types, including duplexes, triplexes, fourplexes, townhouses and cottage clusters in all zones that permit single-family detached housing. Through the Community Plan, the city can address housing variety and affordability in a way that is consistent with the vision and goals for the area.
The purpose of the Community Plan is to help facilitate annexation of the Cooper Mountain area into Beaverton city limits. Once the plan is approved, property owners in Cooper Mountain may apply for annexation and any related land use approvals. The city will likely not act on annexation requests or allow development until after the Community Plan process is complete.
Identifying transportation solutions and implementing them is a priority for the city. The challenges are well-known: two-lane rural roads, reliance on 175th Avenue as a key north-south route, increasing congestion, lack of bicycle and pedestrian facilities, unsafe intersections, and challenging winter conditions. The Community Plan will review and update transportation improvements identified in the Concept Plan and add new information from more recent studies by Washington County. The Community Plan process will determine key street alignments, walking and biking routes, and the potential for future transit service. It will identify funding strategies and establish the roles of the City of Beaverton, Washington County, TriMet, and developers in building new transportation facilities.
The Community Plan will include an infrastructure funding plan, addressing transportation, water, sanitary sewer, storm water, and parks. There is no “silver bullet” for funding these facilities. To find solutions, the funding plan will document what needs to be built, how much it will cost, what projected revenues are available, what new revenue is needed, and then recommend the intended tools and revenue sources that should be used. The Community Plan project will need to engage the development community and partner agencies to determine how development can occur logically and how public facilities can be provided in a timely manner.
Natural resources are a defining characteristic of Cooper Mountain. The Community Plan will identify natural features (including creeks, riparian areas, wetlands and other wildlife habitat) and determine how to balance natural resource protection with infrastructure provision and development. Given the area’s steep slopes and risk for potential landslides, the Community Plan will explore best practices for hillside development and hazard mitigation. The project will consider how to integrate and connect habitat areas and wildlife crossings, incentivize natural resource protection, maintain scenic views, build resilient neighborhoods, and provide new code regulations that implement the vision and policies for Cooper Mountain.
The City of Beaverton has hired a consultant team led by MurraySmith to work with city Engineering staff to develop a Utility Plan for water, stormwater and sewer that provides detailed engineering for Cooper Mountain. The Utility Plan will be coordinated with Community Planning efforts, and the two projects will inform one another throughout the process.
