9. The Administrator may impose conditions on any new shoreline use and developments in a <br />geologically hazardous area as needed to: <br />a. Protect slope stability and minimize erosion, seismic, and/or landslide hazard risks; <br />b. Maintain natural sediment and erosion processes that are integral to the health and <br />sustainability of freshwater ecosystems; <br />c. Minimize the potential for property damage related to seismic events, erosion and/or <br />landslides; <br />d. Minimize the need for structural shoreline stabilization in the future; <br />e. Protect human health and safety; and <br />f. Reduce public liabilities for damages associated with seismic events, erosion and/or <br />landslides. <br />(Ord. 2016-006, 2016) <br /> <br />17B.05.020Q Frequently flooded areas – designation and mapping. <br />1. Designation and mapping: All lands classified as floodway or special flood hazard areas in the <br />Federal Emergency Management Agency report titled "Flood Insurance Rate Maps and Flood <br />Boundary and Floodway Maps" dated November 5, 1980, as now or hereafter amended are <br />designated as frequently flooded areas. The report and maps are on file at Kittitas County. <br />When base flood elevation data has not been provided in the report, the Administrator shall <br />obtain, review, and reasonably utilize any base flood elevation and floodway data available from <br />the Federal Emergency Management Agency, Washington State Department of Ecology, or <br />other qualified source. Where base flood elevation data and floodway delineation are not <br />available either through the report or from a qualified source, historical data, high water marks, <br />and photographs of past flooding shall be used to determine base flood elevations. <br />2. Additional areas may be classified by the Administrator as frequently flooded areas, based upon <br />the following criteria: <br />a. Documented history of flood damage; and/or <br />b. Evidence of stream channel instability and susceptibility to erosion. <br />(Ord. 2016-006, 2016) <br /> <br />17B.05.020R Frequently flooded areas – protection standards. <br />1. New uses and developments within frequently flooded areas, including flood control structures <br />regulated in KCC 17B.05.030, shall comply with the Kittitas County Flood Prevention Ordinance <br />(KCC Chapter 14.08 – December 2014) which is hereby adopted by reference. <br />2. Floodplain storage: New uses or developments shall not reduce the effective flood storage <br />volume within a frequently flooded area. If proposed grading, fill, or other activity would reduce <br />effective flood storage volume, then mitigation is required per KCC 17B.05.020T. below. <br />(Ord. 2016-006, 2016) <br /> <br />17B.05.020S Frequently flooded areas – reporting. <br />1. The Administrator’s approval of a new use or development within a frequently flooded area <br />shall be contingent upon reporting that meets the requirements of KCC <br />14.08.110 through 14.08.130 (December 2014). <br />(Ord. 2016-006, 2016) <br /> <br />17B.05.020T Frequently flooded areas – compensatory mitigation.
