2. New development and re -development shall be designed and configured on <br />the lot to avoid the need for new shoreline stabilization. Removal of failing shoreline <br />stabilization shall be incorporated into re -development design proposals wherever <br />feasible. <br />3. Replacement of lawfully established, existing bulkheads or revetments are <br />subject to the following priority system: <br />a. The first priority for replacement of bulkheads or revetments shall be <br />landward of the existing bulkhead. <br />b. The second priority for replacement of existing bulkheads or revetments <br />shall be to replace in place (at the bulkhead's existing location). <br />4. When evaluating a proposal against the above priority system, at a minimum <br />the following criteria shall be considered: <br />a. Existing topography; <br />b. Existing development; <br />c. Location of abutting bulkheads; <br />d. Impact to shoreline ecological functions; and, <br />e. Impact to river hydraulics, potential changes in geomorphology, and to <br />other areas of the shoreline. <br />5. Proponents of new or replacement hard shoreline stabilization (e.g. <br />bulkheads or revetments) must demonstrate through a documented Riverbank Analysis <br />that bioengineered shoreline protection measures or bioengineering erosion control <br />designs will not provide adequate upland protection of existing structures or would pose <br />a threat or risk to adjacent property. The Study must also demonstrate that the proposed <br />hard shoreline stabilization will not adversely affect other infrastructure or adjacent <br />shorelines. <br />6. Shoreline armoring such as riprap rock revetments and other hard shoreline <br />stabilization techniques are detrimental to river processes and habitat creation. Where <br />allowed, shoreline armoring shall be designed, constructed and maintained in a manner <br />that does not result in a net loss of shoreline ecological functions, including fish habitat, <br />and shall conform to the requirements of the 2004 Washington State Department of Fish <br />and Wildlife (as amended) criteria and guidelines for integrated stream bank protection <br />and shall conform to the requirements of the 2004 Washington State Department of Fish <br />and Wildlife criteria and guidelines for Integrated Stream Bank Protection (2003 as <br />amended), the U. S. Army Corps of Engineers standards (if required), and other <br />regulatory requirements. The hard shoreline stabilization must be designed and <br />approved by an engineer licensed in the State of Washington and qualified to design <br />shoreline stabilization structures. <br />7. Shoreline armoring shall be designed to the minimum size, height, bulk and <br />extent necessary to remedy the identified hazard. <br />W: Legislative Development\SMP-Zoning Code changes 2-25-20 <br />MD:bjs Review and analysis by Barbara Saxton Page 21 of 64 <br />
