14.08.210 Utilities. <br />1. All new and replacement water supply systems shall be designed to minimize or eliminate <br />infiltration of flood waters into the systems and discharges from systems into floodwaters. <br />2. New and replacement sanitary sewage systems shall be designed to minimize or eliminate <br />infiltration of flood waters into the systems and discharge from the systems into flood waters. <br />3. On-site waste disposal systems shall be located to avoid impairment to them or contamination <br />from them during flooding. <br />4. New water wells shall be constructed in compliance with WAC 173-160-171, on high ground <br />that is not in the floodwac. <br />5. Fuel storage tanks shall either be elevated or anchored using methods and practices that <br />minimize flood damage. (consistent with FEMA's "Protecting Building Utilities From Flood <br />Damage" guidebook for techniques). (Ord. 2007-22, 2007; Ord. 2001-03; Ord. 93-18 § 5.1.3, <br />1993). <br />14.08.220 Subdivision proposals and Development. <br />All subdivisions as well as new development shall: <br />1. Be consistent with the need to minimize flood damage. <br />2. Have public utilities and facilities such as sewer, gas, electrical, and water systems located and <br />constructed to minimize flood damage. <br />3. Have adequate drainage provided to reduce exposure to flood damage. <br />4. Where base flood elevation data has not been provided or is not available from another <br />authoritative source, it shall be generated for subdivision proposals and other proposed <br />developments containing greater than 50 lots or 5 acres (whichever is lesser) and shall be <br />included as part of the application and noted on the final mylar, <br />5. All subdivisions shall show on the face of both the preliminary and final plat, for either short or <br />long plats, the boundary of the 100 -year floodplain and floodway. (Ord. 2007-22, 2007; Ord. <br />2001-03; Ord. 93-18 § 5.1.4, 1993). <br />14.08.230 Review of building permits. <br />Where elevation data is not available either through the flood insurance study, FIRM, or from another <br />authoritative source (KCC 14.08.120), applications for floodplain development shall be reviewed to <br />assure that proposed construction will be reasonably safe from flooding. The test of reasonableness <br />is a local judgment and includes use of historical data, high water marks, photographs of past <br />flooding, etc., where available. Failure to elevate at least two feet above the highest adjacent grade in <br />these zones may result in higher insurance rates. (Ord. 2001-03; Ord. 93-18 § 5.1.5, 1993). <br />14.08.235 Changes to Special Flood Hazard Area. <br />1. If a project will alter the BFE or boundaries of the SFHA, then the project proponent shall provide <br />the community with engineering documentation and analysis regarding the proposed change. <br />2. If a CLOMR application is made, then the project proponent shall also supply the full CLOMR <br />documentation package to the Floodplain Administrator to be attached to the floodplain <br />development permit, including all required property owner notifications. <br />14.08.240 Specific standards. <br />In all areas of special flood hazards where base flood elevation data has been provided as set forth <br />
