The intent is to preserve and maintain the single-family residential character of the RS-3 and RS-3A Districts in a manner compatible with the existing amenity and design of development, and to encourage new development that is similar in character to existing development in this District. Emphasis is placed on encouraging neighbourly development by preserving outdoor space and views and by ensuring that the bulk and size of new development is similar to existing development. Neighbourhood amenity is enhanced through the maintenance of healthy trees and planting which reflects the established streetscape. The RS-3 District permits a higher non-discretionary density than the RS-3A District.
