17.18.040 SENSITIVE AREAS ANALYSIS

A sensitive areas analysis shall be submitted with any application for development on property containing known sensitive areas and/or sensitive areas discovered in the process of development, and shall include an analysis, determination, and a development plan including proposed mitigation as identified below. Mapping that reflects the known sensitive areas is available in the development services department. A. Analysis And Determination: The sensitive areas analysis shall provide an analysis and professional determination for each sensitive area. 1. Nondevelopable: a. Wetlands: As determined necessary by the county, an approved jurisdictional wetland delineation report and concurrence report from the United States army corps of engineers shall be required as part of the wetland analysis. b. Steep Slopes: A topographic map depicting the contours of all steep and moderate slopes at an interval of five feet (5') or as determined by the director. c. Natural Waterways And Open Water: A map depicting all stream corridors as defined by their high water marks. 2. Potentially Developable Areas: a. Moderate Slopes: Development may be permitted upon county review and approval of a geotechnical report. The analysis should also include: (1) The location and description of existing natural and manmade features on and surrounding the site, including general topography and soil characteristics and a copy of the soil conservation service soil survey for the site. (2) The location and description of proposed changes to the site, including any grading and excavation, vegetation removal, the location and profiles of proposed roadways, the location of proposed utility lines, the location of existing and proposed buildings and structures, and the location of all other proposed site features. (3) The identification of measures proposed for soil and sediment control, including a schedule of the sequence for the installation of planned erosion and sediment control measures, including anticipated starting and completion dates. (4) Plans for the proposed vegetation of all disturbed site areas. b. Ridgelines: A map depicting the crest and one hundred foot (100') vertical buffer of any significant ridgelines or hilltops within the parcel boundary. Development within this area may be permitted upon county review and approval in keeping with the purpose and standards of this chapter. c. Floodplain, Floodway, And/Or Areas Impacted By Manmade Water Conveyance Systems: A hydrological report including information on groundwater levels, natural and manmade drainage channels and systems (canals), and/or base floodplain elevations. d. Important Habitat Areas: A habitat management plan prepared by a professional qualified in the areas of ecology, wildlife biology, or other relevant disciplines, that identifies the areas inhabited and/or frequently used by any federally listed flora and/or wildlife species (threatened and/or endangered) and includes the following: (1) The ecological and wildlife use characterization of the property explaining the species of wildlife using the areas, the times or seasons the area is used by those species, and the value (e.g., feeding, watering, cover, nesting, roosting, or perching) that the area provides for such wildlife species. (2) Wildlife movement corridors. (3) The general ecological functions provided by the site and its features. (4) An analysis of how proposed development activities impact the important habitat areas and associated species. e. Geologic Hazards: A geotechnical report in compliance with section 17.18.060 of this chapter. f. Wildfire Hazards: A fire protection report that identifies potential fire hazards, mitigation measures, access for fire protection equipment, existing and proposed fire flow capability and compliance with the Utah wildland interface code (see title 15, chapter 15.08 of this code). g. Historic, Prehistoric, And Cultural Resources: Identify any sites and/or structures determined to have historical or archaeological significance to the community, the region, or the state of Utah. This includes properties eligible for the national register of historic places. h. Additional Information: Additional information including input from any of the state of Utah agencies shall be required as determined by the county land use authority.
