In addition to the general purposes listed in Article
I, General Provisions, §
400-2, the regulations for the R-5 Residential District are designed to provide for and encourage the creative development of tracts suitable for clusters of townhouse dwellings surrounded by substantial common green spaces. Other objectives include providing for development designs which can minimize the length and cost of roads and utilities and facilitate the placement of principal uses and improvements so that they are more sensitive to the natural terrain.
