<br /> <br />Kittitas County Shoreline Master Program <br />Chapter 5 86 <br />March 7, 2016 <br />Kittitas County Board of County Commissioners Shoreline Master Program Adopting Ordinance <br />Kittitas County Shoreline Master Program Exhibit A | March 2016 | Page 86 of 339 <br />11. Evaluate appropriate opportunities to remove or prevent structures that confine <br />floodplains and inhibit channel migration. <br />B. Regulations <br />1. Use and development in floodplains shall not significantly or cumulatively increase <br />flood hazards or be inconsistent with comprehensive flood hazard management <br />plans adopted pursuant to RCW Chapter 86.12. <br /> <br />2. New uses or development in shoreline jurisdiction, including the subdivision of land, <br />shall not be permitted when it would be reasonably foreseeable that the uses and/or <br />development would require structural flood hazard reduction measures within the <br />channel migration zone or floodway. <br /> <br />3. The following uses and activities may be appropriate and/or necessary within the <br />channel migration zone or floodway: <br />a. Actions that protect or restore the ecosystem-wide processes or ecological <br />functions. <br />b. Forest practices in compliance with the Washington State Forest Practices Act <br />and its implementing rules. <br />c. Existing and ongoing agricultural practices provided that no new restrictions to <br />channel movement occur. <br />d. Mining when conducted in a manner consistent with Section 6.12 Mining, the <br />shoreline environment designation, and with the provisions of WAC 173-26- <br />241(3)(h). <br />e. Bridges, utility lines, and other public utility and transportation structures where <br />no other feasible alternative exists or the alternative would result in unreasonable <br />and disproportionate costs. Where such structures are allowed, mitigation shall <br />address impacted functions and processes in the affected shoreline. <br />f. Repair and maintenance of an existing legal use, provided that such actions do <br />not cause significant ecological impacts or increase flood hazards to other uses. <br />g. Use and development with a primary purpose of protecting or restoring ecological <br />functions and ecosystem-wide processes. <br />h. Modification or additions to an existing nonagricultural legal use, provided that <br />channel migration is not further limited and that the new uses and/or <br />development includes appropriate protection of ecological functions. <br />i. Use and development in incorporated municipalities and designated urban <br />growth areas, as defined in RCW Chapter 36.70A, where structures exist that <br />prevent active channel movement and flooding. <br /> <br />4. Allow new structural flood hazard reduction measures in shoreline jurisdiction only <br />when it can be demonstrated by a scientific and engineering analysis that they are <br />necessary to protect existing development; that nonstructural measures are not <br />feasible; that impacts on ecological functions and priority species and habitats can <br />be successfully mitigated so as to assure no net loss; and that appropriate
