§ 18.520.010. Purpose and intent.

A. The purpose of Specific Plan No. 12 is to provide for the classification and development of parcels of land as coordinated, comprehensive projects so as to take advantage of the superior environment which will result from large scale community planning. The regulations established by Specific Plan No. 12 are intended to allow a diversity of uses. Development standards are created specifically for the project area while ensuring substantial compliance with the intent of this code. Alternative development standards have been incorporated in this specific plan in return for development sensitivity and increased amenities to serve the inhabitants of this and surrounding community areas.

B. Development standards are proposed to achieve the following objectives:

  1. To provide for the development of safe, comfortable residential areas where residents can enjoy views and a natural setting;

  2. To create a development which blends with the natural setting when viewed from neighboring areas and other parts of the city;

  3. To minimize the alteration of significant natural landforms;

  4. To provide an enriched residential environment with aesthetic cohesiveness, harmonious massing of structures, and interfacing of open space through the utilization of superior land planning and architectural design;

  5. To utilize current practices of good design, architecture, landscape architecture, civil engineering and hillside land planning to preserve, enhance and promote the existing and future appearance and resources of hillside areas.
