Section 4
§ 19.6-70 R-3 High-Density Multifamily Residential District.
A. Purpose. The purpose of this district is to provide areas in the County within the suburban service area where existing middle- to high-density residential development (typically four to 12 units per acre) has been established and land areas which generally appear to be appropriate for such development. The R-3 District is designated based on access to major streets, public water and/or sewer, and schools with suitable capacity to accommodate development at the stated density. A variety of housing densities and styles is encouraged in order to permit a diversity and flexibility in design and layout.
