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. <br />7. New structural stabilization for new non-water-dependent development, including <br />single-family residences, is permitted only if it can be demonstrated that: <br />a. The erosion is not being caused by upland conditions, such as the loss of <br />vegetation and drainage; <br />b. Nonstructural measures, such as placing the proposed use or development <br />further from the shoreline, planting vegetation, or installing on-site drainage <br />improvements, are not feasible or not sufficient; and <br />c. The need to protect primary structures from damage due to erosion is <br />demonstrated through a geotechnical report that states damage was caused <br />by natural processes, such as stream processes or waves. <br />8. New structural stabilization for water-dependent development is permitted only if it can <br />be demonstrated that: <br />a. The erosion is not being caused by upland conditions, such as the loss of <br />vegetation and drainage; <br />b. Nonstructural measures, planting vegetation, or installing on-site drainage <br />improvements, are not feasible or not sufficient; and <br />c. The need to protect primary structures from damage due to erosion is <br />demonstrated through a geotechnical report.
