1. As directed by the Ogden Valley general plan, the purpose and intent of this chapter is to identify and coordinate the application of natural and scenic resource protection guidelines and standards; protect the health, welfare, and safety of Weber County citizens; and minimize the potential degradation of natural and humanmade resources by identifying the cumulative impact on known sensitive areas. This chapter is specifically applicable to new land uses, new structures, and new land development (including amendments to existing developments) in Ogden Valley. This chapter describes mitigation methods that may either be required or recommended. These mitigation methods apply specifically to new land uses, new structures and new land development (including amendments to existing developments). This chapter will apply to all zoning designations in the Ogden Valley.
2. It is intended that the proposed development can be accomplished without substantial interference with or significant adverse effects upon identified sensitive or unique natural or ecological features, important wildlife habitats, or cultural and historic resources.
3. The Ogden Valley Sensitive Lands Maps are available from Weber County.

(Ord. of 1956, § 43-1)

1. Reports. At the request of the county an approved jurisdictional wetland delineation report and concurrence report from the United State Army Corps of Engineers shall be required.
2. Development standards.
   1. Setbacks. No structure, accessory structure, road, or parking area shall be built within the required setback from a river or stream as measured from the high water mark of the river or stream. The high water mark shall be determined by the Weber County engineer. The areas within the setback shall be maintained in a manner that protects the quality of water in the river or stream and the habitat of native vegetation and wildlife along the river or stream.
      1. Structures, accessory structures, roads, or parking areas shall not be developed or located within 100 feet on both sides of the North Fork, South Fork, and Middle Fork of the Ogden River, from the high water mark of the river.
      2. Structures, accessory structures, roads, or parking areas shall not be developed or located within 75 feet on both sides of year-round streams, as determined from the high water mark of the stream.
      3. Structures, accessory structures, roads, or parking areas shall not be developed or located within 50 feet from the high water mark of a natural ephemeral stream.
      4. Structures, accessory structures, roads, or parking areas shall not be developed or located within 100 feet on all sides of Pineview Reservoir, as determined from the high water mark of Pineview Reservoir.
   2. Exceptions.
      1. Bridges or stream alterations approved by the Army Corps of Engineers and state department of natural resources, division of water rights.
      2. Trails built in conformance to chapter 40, Ogden Valley Pathways, of the Land Use Code.
      3. The Ogden River below Pineview Reservoir.
      4. All existing structures, accessory structures, roads, or parking areas prior to the adoption of Ordinance No. 2005-19 River and Stream Corridor Setbacks.
      5. Structures, accessory structures, roads, or parking areas proposed on a lot with a designated buildable area, building envelope, or river or stream corridor setback shown on the recorded subdivision plat, recorded prior to January 1, 2006.
         
   3. Stream flow. No work of any kind shall be allowed in a stream corridor or any change that would alter the flow of a stream without a stream channel alteration permit and/or an approved water right from the state department of natural resources, division of water rights.

(Ord. of 1956, § 43-2)

1. Preservation of important wildlife habitat and preventing the fragmentation of important wildlife habitat are encouraged. When new residential or commercial development is proposed within important wildlife habitat areas, mitigation methods shall be designed and implemented, such as those listed below:
   1. Development standards.
      1. Limitations in areas of wildlife habitat as shown on the Ogden Valley Sensitive Lands Wildlife Map. All development subject to this subsection shall incorporate the following principles in establishing the limits of disturbance and siting of buildings, structures, roads, trails, and other similar facilities to protect important wildlife habitat areas and their functions: Wildlife movement is facilitated across areas dominated by human activities by:
         1. Maintaining connectivity between open space parcels on adjacent and near-by parcels and subdivisions such that the result will be a larger contiguous area of open space;
         2. Locating roads and development away from natural travel corridors used by wildlife, such as riparian areas;
         3. Minimizing fencing types that inhibit the movement of big game species. Use of fencing within subdivisions or boundaries of subdivisions, commercial, industrial or multifamily development shall be minimized;
         4. Minimizing the visual contrast between human-dominated areas, including individual lots, and less disturbed terrain in surrounding areas, for example, by retaining or planting native vegetation and trees around a house or accessory building and maintaining consistent grading between developed and natural areas.
   2. Mimic features of the local natural landscape in developed areas by:
      1. Retaining as much pre-development, high quality habitat as possible, including large patches of natural, vegetated areas that have not yet been fragmented by roads or residential development;
      2. Minimizing levels of disturbance to trees, the under-story vegetation, and other structural landscape features during construction;
      3. Designing house lots in a fashion consistent with local natural habitats, for example, by preserving and landscaping with natural, native vegetation;
      4. Reclaiming disturbed areas, such as degraded landscapes, roadsides, and other infrastructure disturbances by using seed and other selective plantings.
2. When development occurs in mapped important wildlife habitat areas, the state division of wildlife resources (DWR) may provide written recommendations. These recommendations will be considered advisory only, however, the property owner is encouraged to review the recommendations and implement those that are feasible.

(Ord. of 1956, § 43-3)

1. Scenic corridors of the Ogden Valley.
   1. Applicability to property within corridor areas. As directed by the general plan, the regulations contained in this subsection shall apply to all new commercial, industrial and residential structures on lots adjacent to or within 100 feet of the nearest right-of-way of scenic corridors in the Ogden Valley including:
      1. Highway 39. All of Highway 39 beginning at the Pineview Reservoir Spillway and ending at the Eagles Campground in Southfork Canyon with the exclusion of its boundary with Huntsville Town and existing commercial areas.
      2. Highway 166. All of Highway 166 except from the 1900 N. and 5500 E. intersection to the junction with Highway 162. Also the road from the "Y" east to the junction with 5500 E. is excluded.
      3. Highway 162. All of Highway 162 except from its intersection with Highway 158 north to the Wolf Mountain turnoff, and that portion abutting commercial lots in Liberty.
      4. Highway 158. All of Highway 158 from the Pineview Reservoir Spillway to the "Y" in Eden.
      5. Avon Road. All of Avon Road.
      6. Trappers Loop. All of Trappers Loop (Highway 167).
   2. Development standards.
      1. Access/traffic. Access points and driveways connecting directly to the scenic corridor roadways shall be minimized. Shared/common driveways between adjoining projects shall be encouraged.
      2. Fencing. Within the delineated boundaries of the scenic corridors, fences, except agricultural or stock fences, shall be of one of the following styles although commercial, manufacturing, and multifamily uses shall be compatible with requirements of chapter 18C, Ogden Valley Architectural, Landscaping and Screening Ordinance:
         1. Wooden rail;
         2. Architecturally compatible solid wood and natural or cultured stone; or
         3. Various forms of embossed steel or vinyl fencing that may be approved by the Ogden Valley planning commission upon submittal of sample material with the site plans. Chainlink fencing shall not be permitted.
2. Ridge lines. The intent of these provisions is to ensure that development near ridge lines blends with the natural contour of these land forms. Ridge line areas that skyline as viewed from any scenic corridor at a distance of less than 2.5 miles shall be retained in a predominantly natural state and shall incorporate the mitigation criteria listed below. Ridge line development should be sited in such a manner so as not to create a silhouette against the skyline.
   1. Development standards. All structures located within the ridge line area shall not exceed 35 feet in height from lowest elevation of finished or natural grade, whichever is most restrictive, to the top of the structure. All ridge line developments shall be designed to minimize visual impact. All buildings constructed shall make use of neutral, natural colors (white may be used only as an accent color) that blend in to the surrounding area, non-reflective glass, metal and roofing materials, and varied roof lines. A landscape plan shall also be required and shall make use of trees designed to reduce visual impacts.
   2. Methods to reduce scenic quality impact.
      1. Revegetation and reforestation to include the utilization of native or similar horticultural material and assurance that any such revegetation or reforestation will be completed during the first planting season after construction of required improvements, and maintained thereafter.
      2. Removing and stockpiling topsoil prior to any construction grading or excavation and replacement for post-construction revegetation.
      3. Location and installation of utilities in such a way that will cause the least damage to the natural environment.
      4. Review of road system impact on scenic quality.
   3. Historic, prehistoric, and cultural resources.
      1. All development proposals shall identify, preserve and promote any sites and structures determined to have historical or archaeological significance to the community, the region, or the state. This includes properties eligible for the National Register of Historic Places. Specific locations identified in the general plan as historical/cultural sites include, but are not limited to the Blacksmith Shop, Charde Property, Rhodes Property, Brick Kilns, and the Monastery.
