The purpose of the R-2 District is to provide for the development of neighborhoods that include a mixture of single-, two- and multifamily housing and complementary services, encouraging higher densities of new development. Lot sizes are generally smaller than the R-1 Zone to accommodate the smaller housing types that are allowed in the R-2 District. R-2 Districts are areas currently served by public water or are in locations that could support these services. Limited types of commercial uses are allowed in the zone to ensure that the residential character is protected and enhanced. The following regulations shall apply in all R-2 Districts.
