<br /> <br />Kittitas County Shoreline Master Program <br />Chapter 6 124 <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 124 of 339 <br />9. New structural stabilization to protect projects for the restoration of ecological <br />functions or hazardous substance remediation projects is permitted only if it can be <br />demonstrated that nonstructural measures, planting vegetation, or installing on-site <br />drainage improvements, are not feasible or not sufficient. <br />10. An existing shoreline stabilization structure may be replaced with a similar structure <br />if there is a demonstrated need to protect primary uses or structures or public <br />facilities from erosion caused by stream undercutting or wave action. <br />11. Soft shoreline stabilization measures that provide restoration of shoreline ecological <br />functions may be permitted waterward of the OHWM, provided a geotechnical <br />analysis documents that alternative solutions are not feasible or do not provide <br />sufficient protection. <br /> <br />12. Replacement walls or bulkheads shall not encroach waterward of the OHWM or <br />existing structure unless the residence was occupied prior to January 1, 1992, and <br />there are overriding safety or environmental concerns. In such cases, the <br />replacement structure shall abut the existing shoreline stabilization structure. <br /> <br />13. All new, expanded, or replacement shoreline stabilization shall be permitted only if it <br />can be demonstrated that the erosion rate exceeds that which would normally occur <br />in a natural condition, that the measure does not interfere with fluvial hydrological <br />and geo-morphological processes normally acting in natural conditions, and that the <br />proposed measures will not result in a net loss of shoreline ecological functions. <br /> <br />14. For purposes of this Section, "replacement" means the construction of a new <br />structure to perform a shoreline stabilization function of an existing structure which <br />can no longer adequately serve its purpose. Additions to or increases in size of <br />existing shoreline stabilization measures shall be considered new structures. <br />15. Geotechnical reports that address the need to prevent potential damage to a primary <br />structure shall address the necessity for shoreline stabilization by estimating time <br />frames and rates of erosion and report on the urgency associated with the specific <br />situation. Hard armoring solutions should not be authorized except when a <br />geotechnical report confirms that there is a significant possibility that the primary <br />structure will be damaged within three (3) years as a result of shoreline erosion in <br />the absence of hard armoring measures, or where waiting until the need is that <br />immediate, would foreclose the opportunity to use measures that avoid impacts on <br />ecological functions. Where the geotechnical report confirms a need to prevent <br />potential damage to a primary structure, but the need is not as immediate as the <br />three (3) years, the report may still be used to justify more immediate authorization <br />to protect against erosion using soft measures. <br />16. When structural shoreline stabilization measures are demonstrated to be necessary, <br />the following provisions shall apply:
