"Hillsides" means geological features on the landscape having slopes of fifteen percent or greater. "Hydric soil"means a soil that is saturated,flooded or ponded long enough during the growing season to develop anaerobic conditions in the upper part.The presence of hydric soil shall be determined following the methods described in the Federal Manual for Identifying and Delineating Jurisdictional Wetlands. "In-lieu fee(ILF)mitigation" means a program involving the restoration,establishment,enhancement,and/or preservation of aquatic resources through funds paid to a program sponsor to satisfy compensatory mitigation requirements for unavoidable impacts to wetlands and other aquatic resources. Per federal rule,sponsorship of ILF programs is limited to governmental,tribal,or nonprofit natural resource management entities.Similar to a wetland mitigation bank,an ILF program sells credits to permittees whose unavoidable impacts occur within a specified geographic area(service area).When credits are purchased from the ILF program,the permittee's obligation to provide compensatory mitigation is then transferred to the ILF program sponsor.The sponsor is then required to implement mitigation within a specified time frame,working with regulatory agencies to make sure impacts are fully mitigated. ILF programs are approved by the U.S.Army Corps of Engineers and the Washington State Department of Ecology. "Lake"means a natural or artificially created permanent body of water with an average depth of six feet or greater and an area larger than twenty acres,as measured at the ordinary high water mark.

"Land use impacts,low"means low-intensity open space(such as passive recreation and natural resources preservation)and unpaved trails and other similar uses. "Land use impacts,moderate"means residential uses with a density of one unit per acre or less,moderate- intensity open space(parks),and paved trails and other similar uses. "Landslide" means episodic downslope movement of a mass of soil or rock that includes but is not limited to rock falls,slumps,mudflows,earth flows,and avalanches. "Landslide hazard areas" means those areas of the city subject to a risk of landslide based on a combination of geologic,topographic,and hydrologic factors. "Low impact development(LID)" means a stormwater management strategy that emphasizes conservation and the use of existing natural site features integrated with distributed,small-scale stormwater controls to more closely mimic natural hydrologic patterns in developed settings. "Marsh" means an area permanently inundated by water less than six feet deep and occupied predominantly by an emergent wetland vegetation community. "Mitigation" means avoiding, minimizing,or compensating for adverse impacts and includes the use of any or all of the following actions: 1. Avoiding the impact altogether by not taking a certain action or parts of an action; 2. Minimizing impacts by limiting the degree or magnitude of the action and its implementation, by using appropriate technology,or by taking affirmative steps to avoid or reduce impacts; 3. Rectifying the impact by repairing,rehabilitating or restoring the affected critical area; 4. Reducing or eliminating the impact over time by preservation or maintenance operations during the life of the development proposal; Ch.19.04 Definitions 25 City Council Action(11/04/2020)
