A. Design buildings so they solidly meet the ground plane. (See figures.)
+ 1. Building designs requiring a strong structural statement such as extensive cantilevers or cuts and fills on sensitive hillsides shall be prohibited.
+ 2. To the maximum extent feasible, placing buildings on piers such that exterior walls do not continue down to the ground shall be prohibited because of aesthetic and energy efficiency concerns.
o 3. Buildings that firmly meet the ground convey an appearance of greater permanence, and shall be strongly encouraged.
B. Design buildings on hillsides to follow the natural terrain. (See figure.)
+ 1. Buildings shall be located to minimize earthwork and land disturbance.
+ 2. To the maximum extent feasible, buildings shall be sited in locations that are sympathetic to existing contours rather than those that require a building solution that would dominate the site. Buildings shall be designed to follow natural contours rather than modifying the land to accept a building design not tailored to the site. (See section 13.73.070, "Grading", of this chapter and subsection 13.72.030C, "Grading Standards", of this title.)
C. Design buildings to minimize mass and scale. (See figures.)
+ 1. To the maximum extent feasible, building design shall incorporate changes in the planes of walls and changes in the slope and height of rooflines to add variety, create visual interest, and minimize scale.
o 2. Buildings can be made to seem larger or smaller depending on the proportional relationship of separate building elements. Human scale buildings create a comfortable and friendly atmosphere. Building scale should complement rather than dominate the landscape.
+ 3. To the maximum extent feasible, the massing of buildings shall be scaled to harmonize and balance with the specific site and its natural features, especially when buildings are located at tree or landmass edges or in the open, by incorporating the following design principles:
o a. Rooflines and building mass should echo the angles and shapes repeated in the natural landscape, and shift or bend to change directions; and
+ b. Building mass and wall lines shall be broken up to conform to existing slope and avoid unbroken expanses of building mass and walls that can intrude into the natural canyon setting and dominate a site. (Ord. 2012-15, 9-20-2012)
A. Use exterior wall colors that harmonize with the landscape and surrounding buildings;
+ 1. Indigenous materials and colors shall be used in order to mimic natural textures.
+ 2. To the maximum extent feasible, predominant tones on exterior walls shall tend toward neutral colors such as warm earthy hues, dark green of forests, whites, grays and gray brown of the mountains, the tan of grasses, and similar colors. Bright, harshly contrasting color combinations shall be avoided.
B. Use roof surfacing materials that blend with the colors of the adjacent landscape and that are composed of materials which reduce the risk of fire.
+ 1. The color of roof surfacing materials shall be either brown, dark green, gray, or other color that blends in with the surrounding landscape.
+ 2. Wood roofing shingles shall not be allowed in the canyons or foothills because of their potential to ignite during wildfires and increase structural damage. (Ord. 2012-15, 9-20-2012)
See also subsection 13.72.030H, "Tree And Vegetation Protection", of this title for those properties located in the Foothills and Canyons Overlay Zone.
A. Preserve existing trees and vegetation:
+ 1. To the maximum extent feasible, existing concentrations of protected trees and vegetation shall be preserved and remain undisturbed as an important site amenity. For the purposes of this chapter, "protected trees and vegetation" shall be defined as set forth in section 13.04.040 of this title. (See also subsection 13.73.030E of this chapter.)
+ a. Notwithstanding the provisions set forth in this section, existing vegetation located within thirty feet (30') of the primary structure on a site shall be thinned and regularly maintained to help minimize the risk of property damage from wildfire, and to provide space for firefighting equipment and personnel.
o b. When landscaping within this thirty foot (30') firebreak area, use of fire resistant plants is strongly encouraged. (For a list of fire resistant plants, contact the Wasatch-Cache National Forest, Salt Lake Ranger District, or the Utah Division of Forestry, Fire, and State Lands.) See also subsection 13.72.030H3c, "Wildfire Hazards And Tree/Vegetation Removal", of this title.
+ 2. To the maximum extent feasible, dryland species shall be selected for slope revegetation, and irrigation will be minimized to reduce potential problems. (Ord. 2019-04, 2-28-2019)
B. Landscape to retain harmony between the various elements of a landscape and to preserve its original character:
+ 1. Landscaping for new development shall incorporate natural features in the landscape such as trees, significant vegetative patterns, interesting landforms, rocks, water, views and orientation.
+ 2. Landscaped areas shall be an integral part of the development project, and not simply located in leftover space on the site. New planting shall blend in with the existing landscape.
+ 3. All disturbed areas shall be revegetated using native or adapted plant species and materials characteristic of the area.
o 4. Use of fire resistant plants is also strongly encouraged. (For a list of fire resistant plants, contact the Wasatch-Cache National Forest, Salt Lake Ranger District, or the Utah Division of Forestry, Fire and State Lands.) (Ord. 2012-15, 9-20-2012)
+ 1. To the maximum extent feasible, building designs that require extensive cut and fills shall not be allowed.
+ 2. To the maximum extent feasible, modification of the natural terrain shall be minimized by retaining the natural landscape, including existing trees and vegetation.
+ 3. To the maximum extent feasible, slopes steeper than thirty percent (30%) shall not be disturbed.
+ 4. To the maximum extent feasible, buildings, driveways, and roads shall follow the natural contours of the site. Site grading shall follow appendix chapter 33, excavation and grading, of the Uniform Building Code (1997 edition, as amended from time to time) and Best Management Practices (1977) as set forth in the Salt Lake County Erosion-Sediment Control Handbook (1981 edition and as amended from time to time). (Ord. 2012-15, 9-20-2012)
A. Site design shall not change natural drainage patterns. (See section 13.72.080, figure 18 of this title.)
+ 1. All final grading and drainage shall comply with appendix chapter 33, excavation and grading of the Uniform Building Code (1994 edition and as amended from time to time) and best management practices (1977) as set forth in the Salt Lake County erosion-sediment control handbook (1981 and as amended from time to time).
+ 2. To the maximum extent feasible, development shall preserve the natural surface drainage pattern unique to each site as a result of topography and vegetation. Grading shall ensure that drainage flows away from all structures, especially structures that are cut into hillsides. Natural drainage patterns may be modified on site only if the applicant shows that there will be no significant adverse environmental impacts on site or on adjacent properties. If natural drainage patterns are modified, appropriate stabilization techniques shall be employed.
+ 3. Development shall mitigate all negative or adverse drainage impacts on adjacent and surrounding sites.
+ 4. Standard erosion control methods shall be used during construction to protect water quality, control drainage, and reduce soil erosion. Sediment traps, small dams, or barriers of straw bales shall be located wherever there are grade changes to slow the velocity of runoff.
B. Locate buildings outside stream corridor buffer zones:
+ 1. Permanent structures shall be located a minimum of one hundred feet (100') horizontally (plan view) from the ordinary high water mark of stream corridors or other bodies of water. (See figure.) At the discretion of the community development director, and based on site specific studies such as soils or vegetation, setback distances may be reduced according to the modification provisions and criteria set forth in subsection 13.72.060B of this title, or greater setback distances may be required. The community development department, and the health department should be consulted in determining appropriate site specific setback requirements. See also subsection 13.72.030J, "Stream Corridor And Wetlands Protection", of this title.
+ 2. To the maximum extent feasible, developments shall not alter natural waterways.
C. Bridges for stream crossings are recommended. (See figures.)
+ 1. To the maximum extent feasible, the use of culverts to cross perennial streams shall not be allowed. Culverts may be used on small side drainages, across swales, and on ephemeral or intermittent streams. See subsection 13.72.030J, "Stream Corridor And Wetlands Protection", of this title.
+ 2. Bridges and culverts shall be sized to pass 100-year storm events. Concrete or stone head walls and side walls shall be required to maintain the integrity of the bridge structure. (Ord. 2012-15, 9-20-2012)
A. Design traffic circulation to respect existing topography, achieve acceptable slopes, and adhere to minimum width and turning standards:
+ 1. Safe and adequate access shall be provided in all new development. Access shall be of adequate width to allow for snowplowing and snow storage;
+ 2. Access roads shall avoid steep grades and sharp turning radii that can make access, especially in the winter, difficult;
+ 3. Roads and driveways which run perpendicular to the contours of a site shall be prohibited. (See figures.)
B. Provide safe, adequate off street parking with year round access (See figures.)
+ 1. New development shall provide off street parking as required by this land use ordinance.
o 2. Shared driveways and shared parking areas with adjoining owners are strongly encouraged in order to reduce maintenance costs and overall impacts on the environment.
+ 3. Access to off street parking areas shall be from a private driveway or roadway and not directly from a public street or road. Off street parking areas shall be large enough that persons accessing or leaving the site are not required to back out onto a public street unless the community development director or the planning commission determines that the street is not a major thoroughfare and that no safety or traffic flow problems will result.
+ 4. The location of off street parking facilities shall comply with this chapter. Such areas shall be properly screened and be located on land proven to be suitable for development.
C. Design new roads and driveways to reduce their visual impact:
+ 1. To the maximum extent feasible, roads and driveways shall be screened using existing land forms and vegetation and any cuts and fills shall be regraded to repeat adjacent land forms. To the maximum extent feasible, long tangents shall be avoided in favor of curvilinear alignments reflecting topography, and curve side roads as soon as possible after intersection with arterial roads or highways.
+ 2. Cuts and fills for new roads and driveways shall be revegetated with native plant materials. (Ord. 2012-15, 9-20-2012)
A. Place fences to respect existing landforms, follow existing contours, and blend into the natural setting of the site. (See figures.)
+ 1. Fences as part of development on sensitive lands shall be limited to fences necessary to screen service and outdoor areas. (See also subsection 13.72.030C8, "Retaining Walls", of this title.)
+ 2. Fencing used to screen patios, other outdoor areas, and service areas that are adjacent to buildings may be opaque. The use of natural or stained wood for such fencing is strongly encouraged. Other appropriate fencing materials include brick, rock, stone and wrought iron.
+ 3. The following fencing materials shall not be allowed:
a. Solid board;
b. Concrete or concrete block;
c. Chainlink, except around telecommunications facilities and public utility compounds;
d. Plywood;
e. Painted materials; and
f. Vinyl, except rail fences for containment of horses.
+ 4. Wooden rail fences and low rock walls may be permitted along arterial roads and highways, and to delineate property lines.
+ 5. Fences located along property lines and arterial roads or highways are limited to a maximum of forty two inches (42") in height.
+ 6. Solid barrier fences located along arterial roads or highways, or placed directly on a site's front property line, are out of character with the natural setting, block views, and shall be prohibited.
+ 7. Walls and fences shall be reviewed on a site by site basis (during site plan review if applicable) and shall require a building permit. (Ord. 2012-15, 9-20-2012)
