Setbacks to public streets shall be measured from the closest point of a building, including decks or patios, to the street right-of-way. Setbacks to internal drives shall be measured from the building wall to the curbline. Side yard and rear yard setbacks shall be measured from the building, including decks, to the property line. In this regard, the rear yard shall be adjacent to the property line which serves as the rear boundary of adjacent single family homes, and the side yard shall be the area adjacent to the property line which is the boundary of side yards of adjacent residential homes. All side yard and rear yard areas shall remain open and unoccupied, except for storm water management basins and appurtenances, unless other structures are approved in site plan review. Setbacks between buildings shall be measured from building walls. The appropriate dimension for setbacks between building walls which are substantially angled to one another shall be determined by the planning board at the time of site plan review.
