R-2A
Alternate Two-Family Residential District
The R-2A district is intended to provide for the protection of certain older areas of the community developed principally as single-family and two-family uses. Characteristics of the R-2A district are: smaller than average lot widths and area, established building lines much closer to the public right of way and required setback lines, and/or greater lot coverage than allowed in the more recent developing areas where such requirements can be provided. The R-2A district is intended to be located in those areas displaying one or more of the above characteristics. The purpose of this district is to stabilize and preserve the residential character of existing areas through the establishment of bulk regulations in conformity with existing conditions.
