A 528-acre mixed-use development along SW Roy Rogers Road in King City has its first residents moving in, with 26 homes now occupied and plans for 33,000 square feet of shops and restaurants that will add a commercial district to southern Washington County.

Kingston Terrace Town Center, located at the southeast corner of SW Beef Bend Road, received its first 26 certificates of occupancy as of July 8, according to the Beaverton Valley Times. In August 2025, nothing stood at the site.

The project's full buildout calls for 1,186 single-family and multifamily homes across five phases. That would represent a 44% increase over King City's existing 2,713 housing units. The commercial component will line both sides of River Terrace Boulevard with retail and restaurant space, topped by multifamily housing on upper floors.

King City's population has been flat or slightly declining. Portland State University estimates showed the city lost eight residents between 2023 and 2024.

Kingston Terrace reverses that trajectory in a county where growth continues to outpace the state. Washington County added 4,245 residents in 2024 at a 0.7% growth rate, and Portland State projects the county could reach 667,025 by 2030.

Max Carter, King City's lead planner, told the Beaverton Valley Times the full Kingston Terrace development could boost the city's population by roughly 50%, adding about 2,600 residents to a city of approximately 5,100.

"It's one thing to see concepts and stuff on paper, but to actually go on the ground and see it all come together … it is really … pretty amazing," Carter said during a site tour.

Risewell Homes, a national builder formerly known as New Home Co., is the primary developer. The company lists nine communities in Washington County on its website.

Kingston Terrace Town Center is one piece of a larger master-planned community tied to King City's 30-year development plan. Two additional neighborhoods are in the pipeline: Kensington Square, with 87 townhomes near SW 137th Avenue and SW Beef Bend Road, and Sharlin Woods, with 283 homes and townhomes planned for the east side of SW Elsner Road.

What comes next

During the site tour, Carter stood in front of a water-filled stormwater runoff facility near a roundabout on River Terrace Boulevard and described it as the footprint for a future King City City Hall.

The facility will eventually be decommissioned and filled in before the city acquires the land. Carter said land acquisition is an estimated three to four years away; a physical city hall structure could be a decade out.

A temporary park serves residents in the first two completed phases. Carter said a permanent 7-acre park is planned within three to four years.

No specific timeline has been announced for when commercial tenants will open or when later construction phases will begin. Al's Garden & Home, the garden center on adjacent property, plans to stay put, with its main entrance eventually reoriented to face a new Kingston Terrace Boulevard roadway planned to run parallel to the south.
