Kittitas County Shoreline Master Program Chapter 6 108 March 7, 2016 Kittitas County Board of County Commissioners Shoreline Master Program Adopting Ordinance Kittitas County Shoreline Master Program Exhibit A | March 2016 | Page 108 of 339 natural drainage patterns and no reduction of floodwater storage capacity that might endanger other areas. Allow filling, grading, and excavation within the OHWM only when necessary to support water dependent uses, public access, transportation facilities, mitigation, restoration, enhancement, and other uses listed in 6.8.B.2. 3. In evaluating filling, grading, and excavation projects, such factors as total water surface reduction, navigation restriction, impediment to water flow and circulation, impediment to irrigation systems, reduction of water quality, and destruction of fish and wildlife habitat should be examined. 4. Locate and design shoreline fills or cuts to avoid creating a hazard to adjacent life, property, and natural resources systems, and to provide all perimeters of fills with vegetation, retaining walls, or other mechanisms for erosion prevention. B. Regulations 1. Filling, grading or excavation waterward of the OHWM for any use except ecological restoration shall require a conditional use permit. 2. Fill waterward of the OHWM shall be allowed with a shoreline conditional use permit only when necessary to support: a. Water-dependent use; b. Public access; c. Cleanup and disposal of contaminated sediments as part of an interagency environmental clean-up plan; d. Disposal of dredged material considered suitable under, and conducted in accordance with the dredged material management program of the Washington State Department of Natural Resources; e. Expansion or alteration of transportation facilities of statewide significance currently located on the shoreline and then only upon a demonstration that alternatives to fill are not feasible; or f. Mitigation action, environmental restoration, or enhancement project. 3. Fill for the purpose of increasing elevation may be permitted if such can be accomplished in a manner consistent with the policies of this SMP. 4. Fill shall be the minimum necessary to accomplish the use or purpose and shall be confined to areas having the least impact to the stream corridor. Other alternatives should be preferred over fill to elevate new homes in the floodplain, such as increasing foundation height or zero-rise methods such as piers, posts, columns, or other methods. 5. Fill in floodplains shall meet the requirements of Section 5.2 Environmental protection and critical areas and Section 5.3 Flood hazard reduction.
