<br /> <br />Kittitas County Shoreline Master Program <br />Chapter 5 76 <br />March 7, 2016 <br />Kittitas County Board of County Commissioners Shoreline Master Program Adopting Ordinance <br />Kittitas County Shoreline Master Program Exhibit A | March 2016 | Page 76 of 339 <br />and related processes when considered with the characteristics of the river and <br />its surroundings. Such hazards are characterized by abandoned channels, <br />ongoing sediment deposition and erosion, topographic position, and changes in <br />the plant community, age, structure and composition. <br /> <br />4. Classification: Seismic hazard areas – lands subject to severe risk of damage as a <br />result of earthquake induced ground shaking, slope failure, settlement, soil <br />liquefaction, or surface faulting the following classifications shall be designated as <br />seismic hazard and are subject to the requirements of this Section. <br /> <br />5. Classification: Volcanic hazard areas – areas subject to pyroclastic flows, lava flows, <br />debris avalanche, inundation by debris flows, mudflows, or related flooding resulting <br />from volcanic activity. There are no active or dormant volcanoes located within <br />Kittitas County; however Mount Rainer and Mount St. Helens are relatively near. <br />Hazards to Kittitas County residents from these volcanoes are limited to ash <br />deposition. <br /> <br />6. Classification: Mine hazards areas – areas underlain by abandoned mine shafts, <br />secondary passages between shafts tunnels, or air vents. Mine hazards include <br />subsidence, which is the uneven downward movement of the ground surface caused <br />by underground workings caving in; contamination to ground and surface water from <br />tailings and underground workings; concentrations of lethal or noxious gases; and <br />underground fires. <br /> <br />7. Mapping: The approximate location and extent of geologically hazardous areas are <br />shown on maps maintained by the County. These maps shall be advisory and used <br />by the Administrator to provide guidance in determining applicability of the standards <br />to a property. These maps shall be updated periodically as new information <br />becomes available. <br /> <br />P. Regulations—geologically hazardous areas reporting and protection standards <br /> <br />1. New shoreline uses and developments shall be located, designed, constructed, and <br />maintained to avoid geologically hazardous areas. Impact avoidance measures shall <br />include, but not be limited to, locating the use/development outside of the hazard <br />area, reducing the number, size or scale of buildings, driveways and other features; <br />altering the configuration or layout of the proposed development; using <br />environmentally favorable construction materials; implementing special engineering <br />methods for construction, drainage, runoff management etc.; foregoing construction <br />of accessory structures; preserving native vegetation; and other reasonable <br />measures. <br /> <br />2. New uses and developments may be allowed in geologically hazardous areas and/or <br />their buffers only when specifically allowed by this Program and when all reasonable
