Kittitas County Shoreline Master Program <br />4. Locate and design shoreline fills or cuts to avoid creating ahazard to adjacent life, <br />property, and natural resources systems, and to provide all perimeters of fills with <br />vegetation, retaining walls, or other mechanisms for erosion prevention. <br />B. Requlations <br />1. Filling, grading or excavation waterward of the OHWM for any use except ecological <br />restoration shall require a conditional use permit. <br />2. Fill waterward of the OHWM shall be allowed with a shoreline conditional use permit <br />only when necessary to support: <br />a. Water-dependent use; <br />b. Public access; <br />c. Cleanup and disposal of contaminated sediments as part of an interagency <br />environmental clean-up plan; <br />d. Disposal of dredged material considered suitable under, and conducted in <br />accordance with the dredged material management program of the <br />Washington State Department of Natural Resources; <br />e. Expansion or alteration of transportation facilities of statewide significance <br />currently located on the shoreline and then only upon a demonstration that <br />alternatives to fill are not feasible; orf. Mitigation action, environmental restoration, or enhancement project. <br />3. Fill for the purpose of increasing elevation may be permitted if such can be <br />accomplished in a manner consistent with the policies of this SMP. <br />4. Fill shall be the minimum necessary to accomplish the use or purpose and shall be <br />confined to areas having the least impact to the stream corridor. Other alternatives <br />should be preferred over fill to elevate new homes in the floodplain, such as <br />increasing foundation height or zero-rise methods such as piers, posts, columns, or <br />other methods. <br />5. Fill in floodplains shall meet the requirements of Section 5.2 Environmental <br />protection and critical areas and Section 5.3 Flood hazard reduction. <br />6. Pile or pier supports shall be preferred over fill for water-dependent uses and <br />facilities. <br />7. Unless site characteristics dictate othenrvise, fill material within surface waters or <br />wetlands shall be sand, gravel, rock, or other clean material, with a minimum <br />potential to degrade water quality. <br />8. Fill placement shall be scheduled at times having the least impact to fish spawning, <br />nesting patterns, and other identified natural processes. <br />Chapter 6 <br />March 7, 2016 <br />111
