Kittitas County Shoreline Master Program <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. <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 />1 1 . Soft shoreline stabilization measures that provide restoration of shoreline ecological <br />functions may be permitted watenrvard of the OHWM, provided a geotechnical <br />analysis documents that alternative solutions are not feasible or do not provide <br />sufficient protection. <br />12. Replacement walls or bulkheads shall not encroach watenryard 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. ln such cases, the <br />replacement structure shall abut the existing shoreline stabilization structure. <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 />14.For purposes of this Section, "replacement" means the construction of a new <br />Chapter 6 <br />March 7,2016 <br />126
