Kittitas County,WA <br /> § 17A.02.470 CRITICAL AREAS § 17A.02.520 <br /> h. linear fractures in the ground. <br /> 11. Areas below unstable slopes or that have been identified as landslide hazard areas that could be <br /> impacted by landslide run out. <br /> 12. Areas above or adjacent to unstable slopes that could be impacted if the landslide area expands. <br /> (Ord. 2021-016,2021) <br /> § 17A.02.480. Mine hazard areas. <br /> "Mine hazard areas" are areas underlain by abandoned mine shafts, secondary passages between shaft <br /> tunnels, or air vents. Mine hazards include subsidence, which is the uneven downward movement of the <br /> ground surface caused by underground workings caving in;contamination to ground and surface water from <br /> tailings and underground workings; concentrations of lethal or noxious gases; and underground fires. (Ord. <br /> 2021-016,2021) <br /> § 17A.02.490. Mining. <br /> "Mining" means the removal of sand, gravel, soil, minerals, and other earth materials for commercial and <br /> other uses. <br /> (Ord. 2021-016,2021) <br /> § 17A.02.500. Mitigation sequencing. <br /> "Mitigation sequencing" means a process used to guide mitigation decisions and determine the type and <br /> level of mitigation required. It follows a three(3) step process, described in 17A.01.100: <br /> 1. Avoiding the impact altogether by not taking a certain action or parts of an action; <br /> 2. Minimizing impacts by limiting the degree or magnitude of the action and its implementation, <br /> by using appropriate technology, or by taking affirmative steps to avoid or reduce impacts; <br /> 3. Rectifying the impact by repairing,rehabilitating, or restoring the affected environment; <br /> 4. Reducing or eliminating the impact over time by preservation and maintenance operations <br /> during the life of the action; <br /> 5. Compensating for the impact by replacing, enhancing, or providing substitute resources or <br /> environments; and/or <br /> 6. Monitoring the impact and taking appropriate corrective measures. <br /> (Ord. 2021-016,2021) <br /> § 17A.02.510. Monitoring. <br /> "Monitoring"means evaluating the impacts of proposed developments on the biological,hydrological, and <br /> geological elements of such systems, and assessing the performance of required mitigation measures <br /> throughout the collection and analysis of data by various methods for the purpose of understanding and <br /> documenting changes in natural ecosystems and features,including gathering baseline data. <br /> (Ord. 2021-016,2021) <br /> Downloaded from https:Hecode360.com/KI6857 on 2025-05-15 <br />
