37.050 Downtown Outdoor Spaces Site Design Standards

A. General Description. This section addresses the various outdoor spaces that form downtown Lehi, its streets, parking areas, sidewalks, plazas, and other outdoor places, which provide settings for the architecture of Lehi, and connections to and from the various buildings. The design of outdoor downtown spaces shall be equal in quality as the buildings themselves. This will help create a downtown district that is unified and consistent and result in a positive downtown image. B. Purpose. The standards in this section describe how to treat public spaces located in downtown Lehi. These standards apply to the specific streets and places described in the Downtown Lehi Revitalization Plan (2007). These standards provide direction for Lehi City, UDOT, property owners, designers, and developers as improvements are made to both public infrastructure and sites, and privately-owned spaces in the downtown area. C. Streets and Streetscape. Each of the streets in downtown Lehi can contribute to the establishment of a positive place for residents and visitors. The width of the roadway, the number of lanes, on-street parking, street trees and landscaping shape our first impressions of an area. The following Downtown Outdoor Spaces Site Design Standards define the required road and street improvements, as derived from the Downtown Lehi Revitalization Plan (2007). 1. Street-type A: Main Street Historic Core. This portion of Main Street is located between 500 West and 100 East. The segment is both limited and defined by the narrow street right-of-way and the adjacent line of structures or “street wall” along the street edge. Streetscape improvements in this area shall occur within the confines of the right-of-way where possible. In cases where buildings are missing or where they detract from the historic character, the front setback may be re-aligned toward the rear, if the overall effect improves the pedestrian character of the adjacent sidewalk, and with the approval of the Lehi Planning Commission. a. Paving and Surface Materials. Sidewalks and walkways shall be constructed of brick, concrete unit pavers or similar materials that respect and celebrate the historic nature of the area. Color tones shall be medium to dark in tone in order to create a uniform setting for the surrounding 37-94 Downtown Outdoor Spaces Site Design Standards building materials and colors (see Figure 160). Figure 160. Example of concrete unit paver walkway with medium to dark tones b. Lighting and Furnishings. Streetlights and furnishings shall be coordinated throughout Downtown Lehi. Furnishings shall be limited to a select range of benches, trash receptacles, tree grates and bollards. Streetlights shall be selected from a single model line and coordinate with other downtown streetlights. c. Landscape Treatments. Street trees shall be over 35 feet high and wide at maturity, hardy, drought-tolerant, and water conserving. Tree species shall be avoided that will heave paving and sidewalks, that are overly dense or difficult to maintain. 2. Street-type B: Main Street Transition Zone. This segment of Main Street extends from 100 East to 500 East. The roadway has a more open, residential feel than the historic core segment, despite the narrow right-of-way. Streetscape improvements should be contained within the right-of-way, merging the diverse range of adjacent uses within a uniform streetscape design. The following Outdoor Space Site Design Standards shall apply: a. Paving and Surface Materials. Sidewalks shall be standard poured-in-place concrete. b. Lighting and Furnishings. Streetlights and furnishings shall be coordinated throughout downtown. Furnishings shall be limited to a select range of benches, trash receptacles, tree grates and bollards. Streetlights shall be selected from a single model line and coordinate with other downtown streetlights. c. Landscape Treatments.

Tree species shall be avoided that will heave paving and sidewalks, that are overly dense or difficult to maintain. 3. Street-type C: Main Street Business Zone. This section of Main Street extends form 500 East to 850 East. The roadway here is wider than other portions of Main Street and is lined with a range of commercial uses.

Paving and Surface Materials. Sidewalks shall be standard poured-in-place concrete. b. Lighting and Furnishings. Streetlights and furnishings shall be coordinated throughout downtown.

Improvements shall be implemented in consultation with UDOT. The following Outdoor Space Site Design Standards shall apply to State Street: a. Paving and Surface Materials. Sidewalks shall be standard poured-in-place concrete. b. Lighting and Furnishings. Streetlights and furnishings shall be coordinated throughout downtown. Furnishings shall be limited to a select range of benches, trash receptacles, tree grates and bollards. Streetlights shall be selected from a single model line and coordinate with other downtown streetlights. c. Landscape Treatments.

These streets shall be formalized with sidewalks, curb and gutter, park strips and street trees. The following Outdoor Spaces Site Design Standards shall apply: a. Paving and Surface Materials. Sidewalks shall be standard pour-in-place concrete. Bulb-outs shall utilize the same concrete unit pavers or similar materials along the length of Main Street. b. Lighting and Furnishings. Streetlights shall be coordinated throughout downtown. No street furnishings are envisioned on these streets. Streetlights shall be selected from a single model line and coordinate with other downtown streetlights. c. Landscape Treatments. Street trees shall be over 35 feet high and wide at maturity, hardy, drought tolerant, and water conserving. Trees along this street should be distinctly different 37-96 Downtown Outdoor Spaces Site Design Standards than those located on Main Street or other downtown roads. d. Tree species shall be avoided that heave paving and sidewalks, or which are difficult to maintain. e. Park strips shall be planted with drought tolerant turf and/or groundcovers. 7.

The application of fences and walls is dependent on the surrounding uses that need to be screened or buffered, and site context. In general, fences and walls over four feet shall be limited to the rear and sides of buildings. The use of fences and walls shall be limited to locations where they buffer incompatible uses and to meet required buffering and screening requirements. In general, these features shall be constructed of solid materials that fit with the overall feel of the area but shall not use vinyl or chain link fencing.
