SUMMIT COUNTY LAND USE AND DEVELOPMENT CODE <br />CHAPTER 10: Areas and Activities of State Interest <br />• a. Changes in aquifer recharge rates, groundwater levels and aquifer capacity including seepage losses <br />through aquifer boundaries and at aquifer-stream interfaces. <br />b. Changes in capacity and function of wells within the impact area. <br />c. Changes in quality of well water within the impact area. <br />A.11 The determination of effects of the proposed activity on wetlands and riparian areas may include but is not <br />limited to the following considerations: <br />a. Changes in the structure and function of wetlands. <br />b. Changes to the filtering and pollutant uptake capacities of wetlands and riparian areas. <br />c. Changes to aerial extent of wetlands. <br />d. Changes in species' characteristics and diversity. <br />e. Transition from wetland to upland species. <br />f. Changes in function and aerial extent of floodplains. <br />A.12 The determination of effects of the proposed activity on terrestrial or aquatic life may include but is not <br />limited to the following considerations: <br />a. Changes that result in loss of oxygen for aquatic life. <br />b. Changes in flushing flows. <br />c. Changes in species composition or density. <br />d. Changes in number of threatened or endangered species. <br />e. Changes to habitat and critical habitat, including calving grounds, mating grounds, nesting grounds, <br />summer or winter range, migration routes, or any other habitat features necessary for the protection and <br />propagation of any terrestrial animals. <br />f. Changes to habitat and critical habitat, including stream bed and banks, spawning grounds, riffle and side <br />pool areas, flushing flows, nutrient accumulation and cycling, water temperature, depth and circulation, <br />stratification and any other conditions necessary for the protection and propagation of aquatic species. <br />g. Changes to the aquatic and terrestrial food webs. <br />A.13 The determination of effects of the proposed activity on terrestrial plant life or habitat may include but is not <br />limited to the following considerations: <br />a. Changes to habitat of threatened or endangered plant species. <br />b. Changes to the structure and function of vegetation, including species composition, diversity, biomass <br />and productivity. <br />c. Changes in advancement or succession of desirable and less desirable species, including noxious weeds. <br />d. Changes in threatened or endangered species. <br />A.14 The determination of effects of the proposed activity on soils and geologic conditions may include but is not <br />limited to the following considerations: <br />a. Changes to the topography, natural drainage patterns, soil morphology and productivity, soil erosion <br />potential and floodplains. <br />b. Changes to stream sedimentation, geomorphology and channel stability. <br />c. Changes to lake and reservoir bank stability and sedimentation and safety of existing reservoirs. <br />d. Changes to avalanche areas, mudflows and debris fans and other unstable and potentially unstable slopes. <br />e. Exacerbation of seismic concerns and subsidence. <br />A.15 The determination of the risks of a release of hazardous materials from the proposed activity may include but <br />is not limited to the following considerations: <br />a. Plans for compliance with federal and State handling, storage, disposal and transportation requirements. <br />b. Use of waste minimization techniques. <br />• c. Adequacy of spill prevention and response plans. <br />31
