32.05.260 Floodways.
Located within areas of special flood hazard established in SCC 32.05.070 may be areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles, and erosion potential, the following provisions apply:
A. Within an adopted regulatory floodway, Sierra County shall prohibit encroachments, including fill, new construction, substantial improvement, and other new development unless certification by a registered professional engineer is provided demonstrating that encroachments shall not result in any increase in [the base] flood elevation during the occurrence of the base flood discharge.
B. If subsection (A) of this section is satisfied, all new construction, substantial improvement, and other proposed new development shall comply with all other applicable flood hazard reduction provisions of SCC 32.05.130 through 32.05.160. (Formerly 32.22)
