Section 660-007-0035 - Minimum Residential Density Allocation for New Construction

(1) The Cities of Cornelius, Durham, Fairview, Happy Valley and Sherwood must provide for an overall density of six or more dwelling units per net buildable acre. These are relatively small cities with some growth potential (i.e. with a regionally coordinated population projection of less than 8,000 persons for the active planning area).

(2) Clackamas and Washington Counties, and the cities of Forest Grove, Gladstone, Milwaukie, Oregon City, Troutdale, Tualatin, West Linn and Wilsonville must provide for an overall density of eight or more dwelling units per net buildable acre.

(3) Multnomah County and the cities of Portland, Gresham, Beaverton, Hillsboro, Lake Oswego and Tigard must provide for an overall density of ten or more dwelling units per net buildable acre. These are larger urbanized jurisdictions with regionally coordinated population projections of 50,000 or more for their active planning areas, which encompass or are near major employment centers, and which are situated along regional transportation corridors.

(4) Regional housing density and mix standards as stated in OAR 660-007-0030 and sections (1), (2), and (3) of this rule do not apply to small developed cities which had less than 50 acres of buildable land in 1977 as determined by criteria used in Metro's UGB Findings. These cities include King City, Rivergrove, Maywood Park, Johnson City and Wood Village.
