Kittitas County, WA <br />§ 17A.06.100 KITTITAS COUNTY CODE § 17A.06.100 <br />Downloaded from https://ecode360.com/KI6857 on 2025-05-15 <br /> <br /> <br /> <br />3. Geotechnical report contents. When required by this Title, the Geotechnical Report shall include the <br />general critical areas report requirements of KCC § 17A.01.080 in addition to the following: <br />a. A detailed description of the geology and soil conditions of the site; <br />b. Evaluation of the geologic conditions giving rise to the geologic hazard; <br />c. An evaluation of the safety of the proposed project; <br />d. Conclusion and recommendations regarding the effect of geologic conditions on the proposed <br />development; <br />e. 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; and whether or <br />not the project will materially increase the risk of occurrence of the hazard; <br />g. Recommendations concerning drainage practices, vegetation retention and other mitigation and <br />monitoring measures which may be needed to ensure slope stability; <br />h. Recommended erosion and sediment control measures; <br />i. A bibliography of scientific citations; <br />j. Any other specific measures which must be incorporated into the design and operational plan of <br />the project to eliminate or reduce the risk of damage due to the hazard. This shall include a <br />recommendation on the required buffer or setback distance that must be maintained between the <br />proposed development and the hazard to ensure the safety of the development; and The signature <br />and stamp of the engineer or engineering geologist who prepared the Geotechnical Report. <br />4. Channel migration zones studies contents. When required by this Chapter, Channel Migration Zone <br />Studies shall include the general critical areas report requirements of KCC § 17A.01.080, and shall <br />demonstrate the following: <br />a. The parcel on which the development is proposed is effectively protected (disconnected) from <br />channel movement due to the existence of permanent levees that are actively maintained by <br />public agencies or infrastructure such as roads and bridges constructed and maintained by public <br />agencies (not all roads and levees will be considered disconnection points): or <br />b. The proposed development site has minimal risk of channel migration during the next one <br />hundred (100) years as indicated by the existing channel type, land cover (and low likelihood of <br />future alterations in land cover), presence of adjacent toe slope landslide hazard areas, surficial <br />geology, low soil erosion potential, lack of evidence of likely avulsion pathways (including areas <br />upstream of, but proximate to, the site), and/or low inundation frequency(ies). The assessment <br />shall include a review of available data regarding historical channel locations at the site; <br />identification of the site within a broader geomorphic reach of the river system and the general <br />characteristics of that reach; description of existing channel type, existing channel alteration and <br />likelihood of future alterations with changes in land cover; surficial geology, soils and erosion <br />potential; and geotechnical setbacks relating to erosion at the toe of adjacent slope(s). The <br />approach to assessing location shall be generally equivalent to the methods detailed in "A <br />framework for Delineating Channel Migration Zones" (Ecology Publication # 03-06-027), or <br />similar method approved or sanctioned by Ecology.
