Located within areas of special flood hazard established in Section 15.28.060 are 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:
(1) Prohibit encroachments, including fill, substantial improvements, and other development unless certification by a registered professional engineer or architect is provided demonstrating that encroachments shall not result in any increase in flood levels during the occurrence of the base flood discharge. All new construction and substantial improvements associated with any allowed encroachments shall comply with all the applicable flood hazard reduction standards of Section 15.28.150.
(2) Dumping permit required. It is unlawful for any person to dump or place any garbage, trees, brush, dirt, refuse, rubbish, or other waste material in the bed or channel or any natural stream, or in any watercourse, ravine, or gulley which usually carries storm waters or spring runoff waters so as in any way to obstruct or interfere with the flow of such waters, without first obtaining a permit to do so from the Planning Commission.
(3) Under the provisions of 44 CFR Chapter 1, Section 65.12, of the National Flood Insurance Regulations, a community may permit encroachments with the adopted regulatory floodway that would result in an increase in base flood elevations, provided that the community first applies for a conditional FIRM and floodway revision through FEMA.
