[Ord. 5-20 § 2 (Appx. A)] 18.22.410 Classification/designation.

These areas include, but are not limited to, streams, rivers, lakes, coastal areas, wetlands, and areas where high groundwater forms ponds on the ground surface. Frequently flooded areas perform important hydrologic functions and may present a risk to persons and property. Flood hazard areas are depicted on the Federal Emergency Management Agency’sFEMA Flood Insurance Rate Maps (FIRMs). FIRMs display areas of concern including areas that fall within the 100-year floodplain designations of the Federal Emergency Management Agency FEMA and the National Flood Insurance Program. [Ord. 5-20 § 2 (Appx. A)] 18.22.420 Applicability. These standards apply This article applies to any development within frequently flooded areas, unless the proposed activity meets any of the exemptions listed in Chapter 15.15 JCC. The flood damage prevention ordinance (Chapter 15.15 JCC) conforms with the intent of the minimum guidelines (WAC 365-190-110(1)) through directly considering the effects of flooding on human health and safety, together with effects on public facilities and services, through its protection standards. For purposes of this article, “development” is defined as any manmade change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations, storage of equipment or materials, subdivision of land, removal of more than five percent of the native vegetation on the property, or alteration of natural site characteristics.

[Ord. 5-20 § 2 (Appx. A)] 18.22.230 General exemptions.
