Lighting Standards

Lighting Standards

Midvale City has adopted outdoor lighting standards to ensure consistent, efficient and unobtrusive lighting throughout the City. All new development is required to comply with these standards.  n addition, pre-existing outdoor lighting is required to come into compliance with these standards upon application with the Business License Department for a change in ownership, new business in a stand alone structure or in a multi-tenant structure in which the new business utilizes more than 50% of the building square footage on the site, in conjunction with an application for a building permit for any alteration, remodel or expansion of any structure on the site, or in conjunction with changes to the approved site plan.

OUTDOOR LIGHTING STANDARDS. High-pressure sodium, or metal halide light sources are the only allowed light sources for outdoor lighting. Light levels should be designed with minimum light trespass off-site by using a cut-off luminaire that is fully or partially shielded with little or no light distributed above the horizontal plane of the luminaire or other best practices that are available.

1.     Maximum Light Distribution. For uniformity in lighting and prevention of shadows, a four to one (4:1) uniformity ratio shall occur over the site, excluding canopy areas and main building entrances. The maximum allowed average horizontal luminance level and light source shall be as noted in the following table.

2.     Pole Height/Design/ Height. Luminaire mounting height is measured from the parking lot or driveway surface, and may range from twenty feet (20') to thirty five feet (35'), based on:

        a.       Review of the site plan;
        b.       Proposed land uses;
        c.       Surrounding land uses;
        d.       Parking area size;
        e.       Building mass;
        f.        Location of the site with respect to other lighting sources;
        g.       Impacts on the adjacent properties;
        h.       Topography of site; and
        i.        Other site features.

3.     Large Parking Areas. Poles higher than twenty feet (20') are appropriate only for parking areas exceeding two hundred (200) stalls and not in close proximity to residential areas.

4.     Design Standard.

        a.       If metal fixtures or poles are used they should be black or dark brown;
        b.       The base of the pole shall be treated with paint, stain, stucco or another form of decorative cover. All attempts shall be made to place the base of light poles within landscape areas;
        c.       Wall mounted lighting fixtures may not exceed eighteen feet (18’) in height; and
        d.       Lighting located along pedestrian pathways or in areas primarily dedicated to human activity may not exceed twelve feet (12’) in height.

5.     Submission Requirements. An application for development with outdoor lighting must contain the following:

        a.       Plans indicating the location on the premises, and the type of illumination devices, fixtures, lamps, supports, reflectors, installation and electrical details;
        b.       Description of illuminating devices, fixtures, lamps, supports, reflectors, and other devices, that may include, but is not limited to, manufacturer catalog cuts and drawings, including section where required; and
        c.       Photometric data, such as that furnished by manufacturers or similar showing the angle of the cut off or light emission. A point-by-point light plan may be required to determine the adequacy of the lighting over the site.
