Purpose The purpose of this chapter is to preserve the aesthetic character of communities, to improve the aesthetic quality of the built environment, to promote retention and protection of existing vegetation; to promote water efficiency, to promote native wildlife, to reduce the impacts of development on drainage systems and natural habitats, and to increase privacy for residential zones by: 1. Providing visual relief from large expanses of parking areas and reduction of perceived building scale; 2. Providing physical separation between residential and nonresidential areas; 3. Providing visual screens and barriers as a transition between differing land uses; 4. Retaining existing vegetation and significant trees by incorporating them into the site design; 5. Providing increased areas of permeable surfaces to allow for:
4. Meet the on-site recreation needs of project residents;
5. Enhance aesthetics and environmental protection through site design; 6. Allow for continued or adaptive reuse of historic resources while preserving their historic and architectural integrity; 7. Reduce the health and aesthetic impact of waste containers adjacent to streets;
a. Infiltration of surface water into groundwater resources;
8. Promote compatibility between residential and nonresidential uses; and
b. Reduction in the quantity of storm water discharge; and
9. Promote health, safety, and security by minimizing glare and light trespass from outdoor lighting onto adjacent properties.
c. Improvement in the quality of storm water discharge;
6. Encouraging the use of native plant species by their retention or use in the landscape design;
