ORDINANCE Page 10 of 19 <br />“Land use impacts, high” means commercial, industrial, institutional, retail sales, high-intensity <br />recreation (golf courses, ball fields), and residential uses with a density of more than one <br />dwelling unit per acre and other similar uses. <br />“Land use impacts, low” means low-intensity open space (such as passive recreation and natural <br />resources preservation) and unpaved trails and other similar uses. <br />“Land use impacts, moderate” means residential uses with a density of one unit per acre or less, <br />moderate-intensity open space (parks), and paved trails and other similar uses. <br />“Landslide” means episodic downslope movement of a mass of soil or rock that includes but is <br />not limited to rock falls, slumps, mudflows, earth flows, and avalanches. <br />“Landslide hazard areas” means those areas of the city subject to a risk of landslide based on a <br />combination of geologic, topographic, and hydrologic factors. They include any areas susceptible <br />to landslide because of any combination of bedrock, soil, slope (gradient), slope aspect, <br />structure, hydrology, or other factors. <br />“Low impact development (LID)” means a stormwater management strategy that emphasizes <br />conservation and the use of existing natural site features integrated with distributed, small-scale <br />stormwater controls to more closely mimic natural hydrologic patterns in developed settings. <br />stormwater and land-use management strategy that tries to mimic natural hydrologic conditions <br />by emphasizing the following techniques: conservation, use of on-site natural features, site <br />planning, and distributed stormwater best management practices (BMPs) integrated into a <br />project design. <br />“Marsh” means an area permanently inundated by water less than six feet deep and occupied <br />predominantly by an emergent wetland vegetation community. <br />“Mitigation sequence” means a prescribed order of steps taken to reduce the impacts of <br />activities on wetlands, fish and wildlife habitat conservation areas, and buffers. As defined in <br />WAC 197-11-768, mitigation means: avoiding, minimizing, or compensating for adverse impacts <br />and includes the use of any or all of the following actions: <br />1A. Avoiding the impact altogether by not taking a certain action or parts of an action; <br />2B. Minimizing impacts by limiting the degree or magnitude of the action and its <br />implementation, by using appropriate technology, or by taking affirmative steps to avoid <br />or reduce impacts; <br />3C. Rectifying the impact by repairing, rehabilitating or restoring the affected critical <br />areaenvironment; <br />4D. Reducing or eliminating the impact over time by preservation or maintenance <br />operations during the life of the development proposal action; <br />5E. Compensating for the impact by replacing or, enhancing, or providing substitute <br />critical areas resources or environments; and/or;
