Kittitas County,WA <br /> § 17A.06.040 CRITICAL AREAS § 17A.06.050 <br /> C. The Director shall have the authority to require appropriate management of vegetation or land <br /> use within the setback area to minimize the risk of increasing the risk of landslides. <br /> (Ord. 2021-016,2021) <br /> § 17A.06.050. Erosion hazard area standards. <br /> 1. Generally. Alterations or development may be allowed within erosion hazard areas,provided that all <br /> responsible measures have been taken to minimize risks and other adverse effects with erosion <br /> hazards, and the amount and degree of the alteration are limited to minimum needed to accomplish <br /> the project purpose.Prior to approving a development or alteration in or adjacent to an erosion hazard <br /> area, a report will be prepared as defined in KCC § 17A.06.100. Based on this information, the <br /> Director shall determine whether all the following standards are met. <br /> a. The alteration or development includes all appropriate measures to eliminate or otherwise <br /> mitigate risks to health and safety; <br /> b. The alteration or development includes best management practices to prevent, control and <br /> minimize erosion; <br /> C. The alteration or development will not increase erosion potential; <br /> d. The removal and disturbance of vegetation, clearing, or grading shall be limited to the area of <br /> the approved alteration or development; <br /> e. The alteration or development will not increase surface water discharge or sedimentation to <br /> adjacent properties beyond predevelopment conditions, as documented in a geologically <br /> hazardous area risk assessment and/or geotechnical report; <br /> f. The proposed alterations will not adversely impact other critical areas; and <br /> g. Structures and improvements are designed to minimize alterations to the erosive soils and slopes. <br /> 2. Channel migration zones.If County maps or consultation by the Director with qualified professionals <br /> or agencies with expertise indicate that a potential channel migration zone hazard exists on or adjacent <br /> to a proposed development site,the applicant shall either: <br /> a. Locate the proposed development outside of an already defined channel migration hazard area <br /> as indicated on the map; or <br /> b. Submit a Channel Migration Zone Report, as described in KCC § 17A.06.100 prepared by a <br /> qualified geologist, or engineering geologist, or professional engineer, licensed in the state of <br /> Washington with experience in analyzing channel response in the fluvial systems of the Pacific <br /> Northwest. <br /> 3. Permitted alterations and development in channel migration zones. The following alterations and <br /> development shall be allowed as specified below and previous sections: <br /> a. Surface water discharge.Discharge of surface water,provided there are no other alternatives for <br /> discharge. The pipe shall be located on the surface of the ground and be properly anchored so <br /> that it will continue to function under erosion conditions and not create or contribute to adverse <br /> effects on downstream critical areas. <br /> b. Utility lines. Utility lines, when no feasible location is available. Above-ground lines shall be <br /> Downloaded from https:Hecode360.com/KI6857 on 2025-05-15 <br />
