How zoning works in Hillsboro
As a Metro member city, Hillsboro's growth is bounded by the regional Urban Growth Boundary, and continued pressure from its employment base has made UGB expansion and industrial land supply a recurring planning issue. The city has also built out station-area zoning around its MAX light rail corridor to support transit-oriented, higher-density development.
