Kittitas County Shoreline Master Program nearby. lf the professional preparing the geologic hazard area risk assessment concludes that further analysis is necessary, the applicant shall submit a geotechnical report consistent with the provisions of this Section. 6. Geotechnical report (non-channel migration zone): The geotechnical report shall include a certification from the engineering geologist or geotechnical engineer preparing the report, including the professional's stamp and signature. The geotechnical report shall include the following: a. A detailed description of the geology and soil conditions of the site; b. Evaluation of the geologic conditions giving rise to the geologic hazard; c. An evaluation of the safety of the proposed project; 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; andj. 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): lf 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 Chapter 5 March 7, 2016 81
