d. Conclusions and recommendations regarding the effect of geologic conditions on the proposed use or development; e. Conclusions and recommendations on the suitability of the site to be developed; f. A statement regarding the risk of damage from the project, both on- and off-site; and whether or not the project will materially increase the risk of occurrence of the hazard; g. Recommendations concerning drainage practices, vegetation retention and other mitigation and monitoring measures which may be needed to ensure slope stability; h. Recommended erosion and sediment control measures; i. A bibliography of scientific citations; and j. Any other specific measures which must be incorporated into the design and operational plan of the project to eliminate or reduce the risk of damage due to the hazard. This shall include a recommendation on the required buffer or setback distance that must be maintained between the proposed action and the hazard to ensure the safety of the use or development. 7. Hazard present (channel migration zone): If County maps indicate that a potential channel migration zone hazard exists on or adjacent to a proposed use or development site, the applicant shall either: a. Locate the proposal landward of the channel migration hazard area as indicated on the map; or b. Submit a channel migration zone study, prepared by a geologist, engineering geologist, or professional engineer licensed in the state of Washington with at least five (5) years of experience in analyzing channel response in the fluvial systems of the Pacific Northwest, that demonstrates the following: i. The parcel on which the development or use is proposed is effectively protected (disconnected) from channel movement due to the existence of permanent levees maintained by public agencies or infrastructure such as roads and bridges constructed and maintained by public agencies (not all roads and levees will be considered disconnection points); or ii. The proposed use or development site has minimal risk of channel migration during the next one hundred (100) years as indicated by the existing channel type, land cover (and low likelihood of future alterations in land cover); surficial geology, low soil erosion potential; lack of evidence of likely avulsion pathways (including areas upstream of, but proximate to, the site); low inundation frequency(ies). The assessment shall include a review of available data regarding historical channel locations at the site; identification of the site within a broader geomorphic reach of the river system, and the general characteristics of that reach; description of existing channel type, existing channel alterations and likelihood of future alterations with changes in land cover; surficial geology, soils and erosion potential; and geotechnical setbacks relating to erosion at the toe of adjacent slope(s). The approach to assessing local migration shall be generally equivalent to the methods detailed in "A Framework for Delineating Channel Migration Zones" (Ecology Publication # 03-06-027), or similar method approved or sanctioned by Ecology. 8. Based upon the results of the channel migration zone assessment, the Administrator may prohibit or limit use or development within a channel migration zone and/or require a buffer of undisturbed natural vegetation from the edge of the channel migration zone.
