R-5
Medium Density Residential District
The purpose of the R-5 district is to provide a medium density housing option within the Belfair urban growth area. Locations are restricted to sites not significantly impacted by critical areas and slopes. Locations should generally be away from development nodes and commercially zoned areas, beyond a normal walking distance of one-half to three-quarters of a mile. The district allows for a maximum density of five dwelling units per gross acre. Clustering of the dwelling units and properties is encouraged to protect open space and water quality, reduce infrastructure needs, and enhance energy efficiency. Multi family dwelling units are permitted as long as they do not exceed the density requirement and minimize impacts to adjacent single family dwelling units.
