15.04.135 Natural features.
A. The design and development of all subdivisions subject to this title shall preserve, insofar as it is possible, the natural terrain, natural drainage, existing topsoil, unusual rock formations, lakes, rivers, streams and trees.
B. Significant vegetation, including dominant or mature trees and shrubs, shall be retained where possible. When regenerating sites, replacement trees or shrubs shall be selected from indigenous species native to the region. Provisions shall be made to provide adequate hydration and appropriate soil for the replacement trees to ensure successful growth.
C. Land subject to hazardous conditions such as landslides, mud flows, rock falls, shallow water table, open quarries, floods, undermining and polluted or nonpotable water supply shall not be subdivided until the hazards have been eliminated or mitigated.
D. No development, use, fill, construction, excavation, embankment, or alteration on or over any portion of a geologic hazard area shall be permitted which would result in:
1. Dangers to life or property;
2. Human occupation of structures, either permanent or temporary, in geologic hazard areas during periods of high hazard probability;
3. Any type of development involving winter use in an avalanche area;
4. Any type of development where slope failure would result in more than minimal damage; or
5. Any development in a rockfall-prone area, mudflow area, area of potentially unstable slope, seismic area aside known active faults, radioactive area, or area of ground subsidence. (Ord. 711 §1 (Exh. A), 2017)
