R-2M Mixed Residential District

The R-2M district is intended primarily for residential areas that allow for a variety of single-family, two-family, and multifamily dwellings, with gross densities between five and 15 dwelling units per acre.  The R-2M district provides residential neighborhoods with a greater diversity of housing by allowing a mix of both detached and a variety of attached dwelling types in close proximity to each other, rather than separated into different zoning districts.  The R-2M district is to be located in established or redeveloping residential neighborhoods or is to create a transition between single-family, two-family, and higher density multifamily and mixed use areas.  The design of new development, such as building scale and setbacks, parking facility size and location, and yard landscaping, should be complementary to the existing neighborhood and mix of dwelling types.
