R-2 Moderate Density Residential District. This district is intended for application to areas within the Borough where moderate density residential development already exists (in the form of duplex or double homes, conversion apartments, or other multifamily housing structures) or where additional development of this type could be satisfactorily be located. The regulations and uses permitted in this zone primarily encourage residential activities, but also provide for some compatible nonresidential uses, such as professional offices, day care centers, schools, etc. Densities vary throughout the district, but the standards established for the zone are intended to ensure that adequate room is reserved or provided to accommodate the parking and open space needs of each use.
