The R-20 zoning district is intended to implement the comprehensive plan's high density residential land use designation. The district provides for predominantly multifamily housing with the inclusion of duplexes, where appropriate. Development standards encourage neighborhood designs that have a density and configuration that support mass transit service along collector and arterial streets. Generally, developments within this district provide relatively affordable housing near shopping and employment centers.
