<br /> <br />Kittitas County Shoreline Master Program <br />Chapter 6 125 <br />March 7, 2016 <br />9. Materials used for construction of shore stabilization should be selected for long-term <br />durability, ease of maintenance, compatibility with local shore features including <br />aesthetic values, and flexibility for future uses. <br />10. All shore stabilization activities must be designed and constructed to accepted <br />engineering standards. <br />11. Breakwaters, jetties, groins, and weirs are shoreline stabilization structures, which <br />should be allowed only when necessary to support water-dependent uses, public <br />access, shoreline stabilization, or other specific public purposes, and should be <br />designed to protect critical areas and provide for mitigation. <br />B. Regulations <br />1. New uses and developments shall be located and designed to avoid the need for <br />future shoreline stabilization to the extent feasible. <br /> <br />2. Subdivision of land should not create lots that will require shoreline stabilization in <br />order for reasonable use or development to occur. <br /> <br />3. New uses and developments on steep slopes or bluffs shall be set back sufficiently to <br />ensure that shoreline stabilization is unlikely to be necessary during the life of the <br />structure, as demonstrated by a geotechnical analysis. <br /> <br />4. New uses and developments that would require shoreline stabilization which causes <br />significant impacts to adjacent or down-current properties and shoreline areas shall <br />not be allowed. <br /> <br />5. New structural stabilization measures shall only be allowed for the following instances, <br />and then only when necessity is demonstrated based on criteria included in this <br />Section: <br />a. When necessary to protect an existing primary structure; <br />b. In support of new non-water-dependent development, including single-family <br />residence; <br />c. In support of new water-dependent development; and <br />d. To protect projects for the restoration of ecological functions or hazardous <br />substance remediation projects. <br />6. New or enlarged structural shoreline stabilization measures for an existing primary <br />structure, including residences, are permitted only if there is conclusive evidence, <br />documented by a geotechnical analysis, that the structure is in danger from shoreline <br />erosion caused by stream processes or waves. Normal sloughing, erosion of steep <br />bluffs, or shoreline erosion itself, without a scientific or geotechnical analysis, is not <br />demonstration of need. The geotechnical analysis shall evaluate on-site drainage <br />issues and address drainage problems away from the shoreline edge before <br />considering structural shoreline stabilization.
