Conclusions and recommendations on the suitability of the site to be developed; <br />f. A statement regarding the risk of damage from the project, both on- and off-site; <br />and whether or not the project will materially increase the risk of occurrence of <br />the hazard; <br />g. Recommendations concerning drainage practices, vegetation retention and <br />other mitigation and monitoring measures which may be needed to ensure slope <br />stability; <br />h. Recommended erosion and sediment control measures; <br />i. A bibliography of scientific citations; and <br />j. Any other specific measures which must be incorporated into the design and <br />operational plan of the project to eliminate or reduce the risk of damage due to <br />the hazard. This shall include a recommendation on the required buffer or <br />setback distance that must be maintained between the proposed action and the <br />hazard to ensure the safety of the use or development. <br /> <br />7. Hazard present (channel migration zone): If County maps indicate that a potential <br />channel migration zone hazard exists on or adjacent to a proposed use or <br />development site, the applicant shall either: <br />a. Locate the proposal landward of the channel migration hazard area as indicated <br />on the map; or <br />b. Submit a channel migration zone study, prepared by a geologist, engineering <br />geologist, or professional engineer licensed in the state of Washington with at <br />least five (5) years of experience in analyzing channel response in the fluvial <br />systems of the Pacific Northwest, that demonstrates the following: <br />i. The parcel on which the development or use is proposed is effectively <br />protected (disconnected) from channel movement due to the existence of <br />permanent levees maintained by public agencies or infrastructure such as <br />roads and bridges constructed and maintained by public agencies (not all <br />roads and levees will be considered disconnection points); or <br />ii. The proposed use or development site has minimal risk of channel <br />migration during the next one hundred (100) years as indicated by the <br />existing channel type, land cover (and low likelihood of future alterations in <br />land cover); surficial geology, low soil erosion potential; lack of evidence of <br />likely avulsion pathways (including areas upstream of, but proximate to, the <br />site); low inundation frequency(ies). The assessment shall include a review <br />of available data regarding historical channel locations at the site; <br />identification of the site within a broader geomorphic reach of the river <br />system, and the general characteristics of that reach; description of existing <br />channel type, existing channel alterations and likelihood of future alterations <br />with changes in land cover; surficial geology, soils and erosion potential; <br />and geotechnical setbacks relating to erosion at the toe of adjacent slope(s). <br />The approach to assessing local migration shall be generally equivalent to <br />the methods detailed in “A Framework for Delineating Channel Migration
