South Cooper Mountain is turning into one of Beaverton’s busiest construction hotspots, with new homes popping up almost as fast as crews can pour foundations. More than 1,600 homes are already built, and officials say thousands more are approved or under construction as the neighborhood fills in with parks, trails and schools.

The city rolled out an update on Thursday recapping the neighborhood’s progress and goals, calling South Cooper Mountain “one of the city’s most rapidly growing areas” and noting that it is planned for up to 3,500 homes and “more than 240 affordable units,” with Amity Orchards held up as a prime example. According to the City of Beaverton, thousands more homes across the area are already approved or underway.

How the plan is laid out

The South Cooper Mountain concept plan is the blueprint for how this hillside neighborhood will grow up around schools and open space, shaping where homes, parks and everyday amenities actually land. As outlined by the City of Beaverton, the plan calls for a mix of housing types knit together with parks, trails and strong pedestrian connections instead of just long rows of cul‑de‑sacs.

Affordable housing in focus

The city is putting special emphasis on keeping some of this growth within reach for lower‑income residents. Officials highlight a commitment to a range of housing options, including more than 240 units reserved for low‑income families and seniors. Project materials for Amity Orchards describe it as a three‑building affordable community with roughly 164 units and on‑site services, according to architect and project documentation from Otak, while nearby Altura, another affordable complex, opened last year.

Big picture: Cooper Mountain next door

Right next door, the larger Cooper Mountain Community Plan stretches over additional acreage that city and regional planners expect to fill in over the coming decades with new homes and commercial space. The Cooper Mountain area is described by the City of Beaverton as a major future growth hub with the potential to add thousands of homes as part of Beaverton’s long‑range expansion.

What this means for infrastructure

All that growth puts pressure on the basics: water, roads, parks and transit. City and regional officials say it will take carefully coordinated investment to keep services from lagging behind the rooftops. The Willamette Water Supply Program has already coordinated major pipeline work to serve the new development, according to the Willamette Water Supply Program, and supplemental transportation and parks fees are designed to help pay for the roads and green space that will support those new neighborhoods, as reported by Metro.

City staff say detailed site plans, permits and community engagement will keep rolling out as builders finish subdivisions and mixed‑use parcels. For neighbors trying to track what is coming to their hillside, the city’s planning pages and project materials will remain the go‑to place for the latest schedules and documents.
