Medium-Density Residential 20 District

The Medium-Density Residential 20 Zoning Districts are generally intended for single-family neighborhoods adjacent to high-density areas. These zoning districts are designed to conform to existing development patterns rather than encourage major expansions beyond defined neighborhoods. Most areas within this district are connected to municipal water but not to municipal sewers. Specific provision is provided for alternative residential development of certain property of substantial size in the R-30 Zoning District.
