From the Introduction:
Hillsides pose unique challenges for the development of residential neighbourhoods. Meeting these challenges requires a shift from traditional methods of servicing, subdivision layout and building form. The growing awareness of the value and frailty of ecosystems in hillside areas has resulted in increased demands to protect these environmentally sensitive areas. Growing awareness of the financial cost to maintain servicing in hillside areas and the social and economic impacts of providing primarily only large lot single family dwelling housing opportunities, has resulted in a demand to re-examine the very nature of hillside development.
