Whereas the hillside areas of the City differ from the City's flatlands, hillsides necessitate different provisions for their development and their protection. The Hillside Protection Regulations are established to achieve, among others, the following objectives:
(a) To permit development on hillside areas while conserving and promoting the public health, safety, convenience and general welfare by minimizing water run-off and soil erosion problems incurred in adjustment of the topography to meet development needs;
(b) To use the best accepted design, landscape architecture, architecture and civil engineering to preserve, enhance and promote the existing and future appearance and resources of hillside areas;
(c) To preserve and enhance the natural beauty of the landscape by encouraging the maximum retention of natural topographic features such as natural drainage swales, streams, slope ridge lines, rock outcroppings, vistas from and of the hillsides, trees and other natural plant formations and to retain the sense of identity and image that the hillside areas now impart to the City.
