Cedar Mill sits in unincorporated Washington County, north of Beaverton along Cornell Road, with the Sunset Highway to the south and the West Hills rising to the east.
Like Aloha and Bethany, Cedar Mill has never incorporated, so county rather than city rules apply to any public-land use, a detail that occasionally surprises planners used to working with a single city hall contact.
What Cedar Mill offers a plan
- A quiet, mostly residential base near the Sunset Highway corridor
- Restaurant venues for smaller donor and corporate gatherings
- Proximity to the Nike and Intel workforce that commutes along Cornell
- A narrow stretch of Cornell Road toward the West Hills that limits truck access
North of Beaverton, below the West Hills
Cedar Mill is unincorporated, sitting between Beaverton and the Sunset Highway with the forested West Hills rising just to the east. The area is almost entirely residential, built along Cornell Road, with small commercial nodes rather than a defined downtown.
Its location puts it within easy reach of the Nike and Intel commute corridors without being inside either company's immediate footprint, which makes it a bedroom community for tech workers rather than a business district in its own right.
Cedar Mill's business district, sometimes called the Cedar Mill Business Center, is small but includes a mix of medical offices, banks, and service businesses along the Cornell Road corridor rather than any large corporate campus.
Smaller gatherings, not exhibit floors
Show-related work touching Cedar Mill tends to be smaller corporate gatherings and donor events held in local restaurants; the area mostly feeds attendees and crew into programs actually based in Beaverton or Hillsboro rather than hosting anything itself.
Cornell Road narrows toward the hills
Cornell Road tightens as it climbs toward the West Hills, which limits the size of vehicle that can comfortably access the eastern edge of Cedar Mill. Truck routing generally prefers Cornell Pass Road or 185th Avenue to reach the Sunset Highway corridor rather than threading the narrower stretch.
- Route larger vehicles via Cornell Pass Road or 185th rather than upper Cornell Road
- Confirm parking at whichever restaurant venue is hosting the gathering, since lots here are small
- Expect a straightforward run to Beaverton or Hillsboro, longer to downtown or the convention center
What we lock down first
As with the other unincorporated Washington County areas, planning starts with the destination venue's rules; Cedar Mill's contribution is lodging, a quiet meeting space, or a place for attendees to land before heading to the actual show floor.
Because there is no city hall in Cedar Mill itself, questions about street use or public-land permits route through Washington County directly, a step some planners forget to budget time for.
A community library that doubles as a meeting point
The Cedar Mill Community Library, part of the Washington County Cooperative Library Services network, gives the area a genuine civic gathering point beyond the restaurants along Cornell Road. It is not an event venue in the trade-show sense, but it signals that Cedar Mill has real community infrastructure rather than being purely a drive-through neighborhood.
That civic character extends to the area's parks and greenways, which residents use heavily on weekends, another reason weekday timing tends to work better than weekend bookings for anything involving local parking.

Close enough to house commuting employees, but it is not adjacent to either company's main campus footprint.
