The Borough of Penns Grove is hereby divided into districts of different types, each type being of such number, shape, kind and area and of such common unity of purpose and adaptability of use that are deemed most suitable to carry out the objectives of this chapter.

Every parcel of land and every building or other structure in the Borough, except as otherwise provided by law or by ordinance, shall be subject to the regulations, restrictions and requirements specified for the district in which it is located.

Where district boundaries are indicated as approximately coinciding with the center lines of streets, highways, railroad lines or streams, such center lines shall be construed to be such boundaries.

Where district boundaries are so indicated that they approximately coincide with lot lines, such lot lines shall be construed to be said boundaries.

Where district boundaries are so indicated that they are approximately parallel to center lines of streets or highways, such district boundaries shall be construed as being parallel thereto and at such distance therefrom as indicated on the Zoning Map.

Where district boundaries divide a lot, the locations of such boundaries are deemed to be lines which connect two identification points.

R-2 Residential 2 District. The purpose and intent of this district is to retain the character and to maintain the existing medium residential density areas where single-family homes are permitted, as well as variations on single-family attached homes, and to encourage serviceable and efficient land development while providing for the preservation of permanent open space and to create conditions conducive to carrying out the broad purposes of this chapter.
