Kittitas County Shoreline Master Program structure to perform a shoreline stabilization function of an existing structure which can no longer adequately serve its purpose. Additions to or increases in size of existing shoreline stabilization measures shall be considered new structures. 15. Geotechnical reports that address the need to prevent potential damage to a primary structure shall address the necessity for shoreline stabilization by estimating time frames and rates of erosion and report on the urgency associated with the specific situation. Hard armoring solutions should not be authorized except when a geotechnical report confirms that there is a significant possibility that the primary structure will be damaged within three (3) years as a result of shoreline erosion in the absence of hard armoring measures, or where waiting until the need is that immediate, would foreclose the opportunity to use measures that avoid impacts on ecologicalfunctions. Where the geotechnical report confirms a need to prevent potential damage to a primary structure, but the need is not as immediate as the three (3) years, the report may still be used to justify more immediate authorization to protect against erosion using soft measures. 16.When structural shoreline stabilization measures are demonstrated to be necessary, the following provisions shall apply: a. The size of stabilization measures shall be limited to the minimum necessary. Use measures designed to assure no net loss of shoreline ecologicalfunctions; b. Soft approaches shall be used unless demonstrated not to be sufficient to protect primary structures, dwellings, and businesses; and c. Publicly financed or subsidized shoreline erosion control measures should not restrict appropriate public access to the shoreline except where such access is not feasible because of incompatible uses, safety, security, or harm to ecological functions. See Section 5.4 Public access. Where feasible, incorporate ecological restoration and public access improvements into the project. 17. Breakwaters, jetties, groins, and weirs shall: a. Be located waterward of the OHWM and shall be allowed only where necessary to support water-dependent uses, public access, shoreline stabilization, or other specific public purposes; and b. Require a conditional use permit; except for those structures installed to protect or restore ecological functions. 18. Shoreline stabilization projects shall be designed to protect critical areas and shall avoid and reduce significant ecological impacts by providing for mitigation according to the sequence in Section 5.2.8.2. 19. Public access shall be required as part of pubtieailyp!,[gly-financed shoreline erosion control measures. 20.Shoreline stabilization projects shall be designed and constructed to avoid or minimize impacts to sediment transport.
