Kittitas County,WA <br /> § 17A.06.020 KITTITAS COUNTY CODE § 17A.06.030 <br /> "A Framework for Delineating Channel Migration Zones," Washington Department of <br /> Ecology, 2003, as amended). Maps delineating the one-hundred-year channel migration <br /> hazard area shall be of a scale and format specified by the department. <br /> d. Seismic hazard areas. Seismic hazard areas shall include areas subject to severe risk of damage <br /> as a result of earthquake induced ground shaking, slope failure, settlement, soil liquefaction, <br /> lateral spreading, or surface faulting. <br /> e. Volcanic hazard areas. Volcanic hazard areas shall include areas subject to pyroclastic flows, <br /> lava flows,debris avalanche,inundation by debris flows,mudflows,or related flooding resulting <br /> from volcanic activity.There are no active or dormant volcanoes located within Kittitas County; <br /> however, Mount Rainer and Mount St. Helens are relatively near. Hazards to Kittitas County <br /> residents from these volcanoes are likely limited to ash deposition. <br /> f. Mine hazard areas. Mine hazard areas shall include areas underlain by abandoned mine shafts, <br /> secondary passages between shaft tunnels,or air vents.Mine hazards include subsidence,which <br /> is the uneven downward movement of the ground surface caused by underground workings <br /> caving in; contamination to ground and surface water from tailings and underground workings; <br /> concentrations of lethal or noxious gases; and underground fires. <br /> 3. Mapping. The approximate location and extent of geologically hazardous areas are shown on maps <br /> maintained by the County. These maps are useful as a guide for project applicants and/or property <br /> owners but do not provide a conclusive or definitive indication of geologically hazardous area <br /> presence or extent. Other geologically hazardous areas may exist that do not appear on the maps,and <br /> some geologically hazardous areas that appear on the maps may not meet the geologically hazardous <br /> areas designation criteria.The County shall update the maps periodically as new information becomes <br /> available and may require additional studies during the development review process to supplement <br /> and/or confirm the mapping. Historic maps showing the locations of known coal mines within the <br /> County are available from the Washington Department of Natural Resources. <br /> (Ord. 2021-016,2021) <br /> § 17A.06.030. General protection standards. <br /> 1. Generally.New developments shall be located and/or engineered and constructed to minimize risk to <br /> health and safety, protect the building and occupants from the hazard, and not increase the risk of <br /> landslides or erosion that could impact either other properties,public resources,or other critical areas <br /> such as wetlands and fish and wildlife habitat conservation areas.If impacts to other properties,public <br /> resources or other critical areas cannot be avoided these impacts should be mitigated for.The Director <br /> may impose conditions on alterations and development in a geologically hazardous area as needed to: <br /> a. Protect slope stability and minimize erosion, seismic, and/or landslide hazard risks; <br /> b. Maintain natural sediment and erosion processes that are integral to the health and sustainability <br /> of freshwater ecosystems as well as minimizing impacts to stream and river processes such as <br /> channel infill, channel migration or flooding; <br /> C. Minimize the potential for property damage related to seismic events,erosion and/or landslides; <br /> d. Minimize the need for stream or river bank stabilization in the future; <br /> e. Protect human health and safety; and <br /> f. Reduce public liabilities for damages associated with seismic events,erosion and/or landslides <br /> Downloaded from https:Hecode360.com/KI6857 on 2025-05-15 <br />
