Urban Growth Boundary Expansion
Cooper Mountain UGB Expansion
On May 31, 2018, Beaverton submitted the expansion proposal to Metro, the regional government. In the proposal, the city asks Metro to add the 1,232-acre Cooper Mountain Urban Reserve to the Portland region's urban growth boundary (UGB). A copy of the proposal is here. Beaverton presented the proposal to the Metro Council on June 19, 2018.
The public comment period closed on July 9, 2018. Metro will begin a round of public hearings on September 20, 2018. For the latest news on the 2018 growth decision, you can check Metro's website here.
Beaverton's proposal is the start of a long process to request that the area be added to the UGB. The UGB determines where urban development can occur in the region and is established by the Metro Council. Currently, there is limited land for new neighborhoods within the UGB. If the application is successful, this would allow new neighborhoods, roads and city services to be added to the area in the future.
Cooper Mountain Urban Reserve Key Facts
Total acres: 1,232
Developable acres: About 600 (because parks, natural resource areas and slopes limit developable area)
Expected housing units: 3,700
Application due: May 31, 2018
This step is being taken now because:
- We are experiencing a housing shortage that contributes to rising prices and affordability challenges. Planning ahead for new units can help prevent the problem from getting worse.
- Applying for a UGB expansion helps implement the South Cooper Mountain Concept Plan Opens a New Window. , a plan Beaverton completed with community input that covered North Cooper Mountain, Cooper Mountain Urban Reserve and South Cooper Mountain.
- South Cooper Mountain, the city's current area for developing new larger neighborhoods, just south of the urban reserve, already has 2,600 home lots approved, and other developments on the way. It likely will be built out and not have developable land available by 2023.
- Adding land to the growth boundary takes a long time. If the application is successful, it will likely be 5 to 10 years before a significant number of houses are built.
- UGB expansion applications of this size are only accepted every six years.

Beaverton sent letters to all property owners in December, 2017. It has also notified Washington County, neighboring cities and other agencies that provide services, such as Clean Water Services, Tualatin Valley Water District, Tualatin Hills Park & Recreation District and others.
Urban growth boundary: A line to control urban expansion into farm and forest lands and promote the efficient use of land, public facilities and services inside the boundary.
Urban reserve: An area of land suitable for accommodating new development during the next 50 years.
Cooper Mountain Urban Reserve Area: An approximately 1,200-acre area at the southwest corner of Beaverton. It is north of South Cooper Mountain, east of Grabhorn Road, south of Kemmer Road and west of the current Beaverton boundary. About 600 acres of the area are developable.
