1. High intensity light beams, such as searchlights or laser lights, except when used by federal, State, or local authorities; or
2. High intensity LED or neon lighting fixtures mounted around the interior or exterior of a window, door, or other architectural feature on a structure.
D. Luminous Tube Lighting. Luminous tube lighting (e.g., neon, rope lighting, etc.) is prohibited on building exteriors and in configurations where it outlines a window or glass door from the inside of a structure.
(Ord. 2020-36, passed 12-2-2019)
A. Applicability.
1. An exterior lighting plan shall be required for all areas proposed for illumination that exceed 10,000 square feet in area.
2. Projects with multiple areas proposed to be illuminated (such as separate parking lots) shall submit a site lighting plan if the sum of the multiple areas exceed 10,000 square feet.
B. Elements to Include. Regardless of whether an exterior lighting plan is prepared, a site plan, or building permit application, as appropriate, shall indicate the following:
1. Exterior lighting fixture type;
2. Exterior lighting pole height;
3. Exterior lighting fixture shielding; and
4. A statement by the applicant that any proposed exterior lighting complies with the applicable requirements in this section.
C. Certification Required. Certification must be provided by the person preparing a lighting plan that the proposed development complies with the exterior lighting standards of this section.
(Ord. 2020-36, passed 12-2-2019)
All lighting fixtures designed or placed so as to illuminate any portion of a site shall meet the following requirements:
A. Shielding.
1. Overhead lighting fixtures shall be designed to prevent light from emitting upwards towards the sky.
2. Under canopy lighting fixtures should be completely recessed within the canopy.
3. Wall packs shall be cut-off and wall-mounted floodlights shall be shielded (e.g., true cutoff type bulb or light source not visible from off-site) to direct light downward.
4. Exterior lighting fixtures located on private property and visible from a residential land use shall be configured so that the source of illumination (the bulb) is not visible from the residential land use (see Figure 5.4.6.A: Light Shielding).

B. Fixture Height.
1. Lighting fixtures shall be a maximum of 30 feet in height within the parking lot and shall be a maximum of 15 feet in height within non-vehicular pedestrian areas.
2. All light fixtures located within 50 feet of any single-family detached or duplex dwelling shall not exceed 15 feet in height.
C. Lamp Type.
1. Incandescent, florescent, metal halide, light-emitting diode (LED), or color corrected high-pressure sodium lamps are permitted.
2. Non-color-corrected high pressure sodium lamps are prohibited.
3. Other lamp types are allowed when the color emitted is similar to the permitted lamp types.
4. The same lamp type must be used for the same or similar types of lighting throughout a development.
D. Mounting Location. Exterior lighting shall be mounted and configured in such a manner so that the cone of illumination is contained on-site and does not cross any lot line around the perimeter of the site (see Figure 5.4.6.D: Mounting Location).

E. Appearance.
1. Exterior lighting fixtures shall be designed as an integral element that complements the design of the project through compatible style, material, and color.
2. Exterior lighting fixtures shall be designed in a consistent and coordinated manner for the entire site.
(Ord. 2020-36, passed 12-2-2019)
Exterior lighting shall be designed and located such that the maximum illumination measured in footcandles at ground level at any lot line shall not exceed the standards in Table 5.4.7: Maximum Illumination Levels.
Type of Abutting Use or Zoning District [1] | Maximum Illumination Level at the Lot Line (Footcandles) [2] |
Type of Abutting Use or Zoning District [1] | Maximum Illumination Level at the Lot Line (Footcandles) [2] |
Single-family residential or duplex use or land zoned for single-family development | 0.5 |
Multi-family or mixed-use development or land zoned for multi-family or mixed-use development | 0.5 |
Mixed-use development or land zoned for mixed-use development | 1.5 |
Institutional use [3] | 2.0 |
Commercial or industrial use or land zoned for uses other than residential | 2.5 |
Public or private street right-of-way | 5.0 |
NOTES: [1] These are the kinds of uses or zoning districts that abut the development. The maximum allowable illumination along any lot line shared with a single-family residential use is 1.0 footcandles, regardless of the type of use deploying the exterior lighting. [2] In cases where a single development occupies multiple lots, the lot line shall be the lot line(s) around the perimeter of the project. | |
