The R-4-C zoning district is intended to implement the comprehensive plan's low density residential – conservation overlay land use designation. The district standards permit limited residential development within areas that contain significant environmental constraints such as wetlands, frequently flooded areas and steep slopes. These constraints place practical limits on building intensity and provide for the clustering of new development to further protect critical areas and to retain additional open space.
