The regulations set forth in this section or set forth elsewhere in this chapter when referred to in this section are the district regulations in the “R-3” Multiple Dwelling District. This district is composed of certain medium-density residential areas representing a compatible commingling of two-family and multi-family dwellings, including certain open areas where similar residential development appears likely to occur. It is the intent of this district to provide for an environment of medium-density dwellings plus certain additional uses such as schools, parks, churches, and facilities which serve the residents living in the district. Large apartments with corresponding proportions of open space may be developed under prescribed standards of density and open space. In addition to large areas allocated for this district, it has a useful application as a buffer or transition zone along major streets and bordering shopping centers.
