Lighting permitted shall be limited to those levels necessary to provide safety and security to the site.

Use of low intensity lighting for aesthetic purposes in order to enhance or accent building features, public art, or landscape architectural features of a project is encouraged. Such lighting shall not spill over onto or extend beyond the property line or into adjacent public right-of-way.

All lighting systems shall meet adopted uniform codes and standards of the city.

All lighting system components shall be kept in good repair and service. Periodic cleaning, painting and servicing of supports, globes, fixtures and foundations is required. Poor maintenance shall be considered a public nuisance.

Any outdoor lighting system erected, installed, modified or reconstructed without proper plans and permit approvals;

Flashing, alternating, blinking or moving lights, other than traffic or hazard lights or those permitted under the sign regulations contained in Chapter 17.40;

Unshielded pack lighting and areawide flood lighting;

High intensity discharge mercury vapor security lights in other than rural residential or open space/agricultural zones;

Searchlights or laser lights used on an ongoing basis for the purpose of commercial advertising;

Drop down lens, except where the lenses are clear, nondiffusing, and do not permit viewing of the lamp at or above the horizontal plane located at the bottom of the fixture;

Any lighting that causes glare or spillover as defined by this chapter.

Style, size, height and location of any poles used to support luminaires;

Style, size, height and location of any foundation systems (i.e., pedestals) upon which light poles may be erected;

Style, type, location and quantity of luminaires, whether pole mounted, bollard mounted or building mounted;

Type, wattage, lumens and correlated color temperature of lamps;

Shields, cut-off mechanisms, or diffusers used with each luminaire;

Construction structural and mounting details for all installations;

All exterior lighting plans shall include photometric calculations consisting of a point-by-point footcandle layout based upon a minimum 25 foot grid center extended to 25 feet beyond the property line for both initial lighting values and maintained lighting values;

Lighting plans shall be prepared to scale, and shall be accompanied by dimensioned detail sheets, materials catalogues, and specifications to aid in the identification and evaluation of proposed lighting system components.

Lamps shall be shielded or recessed within the luminaire to prevent visibility or the emission of light at or above the horizontal plane located at the bottom of the fixture.

Luminaires shall be directed away from all adjacent properties and streets/rights-of-way to avoid glare and spillover as defined in this chapter.

Maintained lighting values for outdoor parking areas shall not exceed seven foot-candles on 95% or more of the grid points within the parking area on the photometric plan.

Light poles shall not exceed 25 feet in height in all commercial, industrial and institutional zones, except within 100 feet of residential zones, where the maximum height shall be 20 feet. Light poles in residential zones shall not exceed 20 feet in height.

All lighting within parking lots shall be located in curbed planters. Concrete pedestals, bases or foundations for the light pole within the planters over six inches in height shall be decorative. Light poles placed in hardscape areas shall be mounted flush with the surrounding hardscape.

The following minimum horizontal clearances shall be maintained from light poles and pedestals:

The following minimum vertical clearances shall be maintained by luminaires and light pole areas:

All lamps over 100 watts shall emit 60 lumens or more of light per watt of electrical power.

All outdoor lighting systems shall be designed to include an automatic shutoff control with manual override capability to reduce at least 50% of the energy usage of the system from twelve (12:00) a.m. until one hour before daylight, unless otherwise approved by the community development director for safety or security reasons.

Lighting shall be consistent among fixtures used throughout the project so that single fixtures or small groups of fixtures shall not be of unusually high intensity or brightness such that hot spots are created.

All lighting fixtures, including luminaires, poles and pedestals, shall be decorative, compatible with and appropriate in scale, intensity and height to the architecture and use of the building(s) on the site and in the surrounding area.

The correlated color temperature of the lamps shall be compatible with the architecture and use of the building(s) on the site and in the surrounding area.

All walkway lighting, public space lighting, and patio area lighting shall be kept to human scale. Bollard style lighting is preferred.

Incandescent lamps totaling 100 watts or comparable compact fluorescent lamps used in decorative fixtures at entrances/exits of residences;

Low-intensity lighting used for aesthetic purposes in order to enhance or accent building features, public art, or landscape architectural features, provided that such lighting does not result in glare or spillover as defined by this chapter and is not part of a project of which a lighting plan is required;

Athletic field lights within a public park or school campus established pursuant to special plans meeting recognized standards for such facilities constructed in accordance with a photometric plan for these facilities;

Navigation beacons, aircraft warning lighting upon towers or similar structures, hazard markers, railroad signals and crossing warning devices;

Security lighting for prisons, jail facilities, medical facilities or special health care facilities;

Traffic control devices;

Seasonal lighting displays used in conjunction with special holidays or religious celebrations so long as the glare is not sufficient to pose safety hazards to pedestrians and motorists, or cause sufficient attraction to result in creation of a nuisance or hazard to vehicular traffic;

Temporary sale or special event lighting as permitted through the issuance of appropriate permits by the city;

Repair or replacement of individual lighting fixtures, provided that the fixture and/or the luminaire repaired or replaced does not exceed the intensity of the original lighting fixture;

Safety or security lighting within single-family residential neighborhoods recommended by police or special security inspections as part of a neighborhood watch program provided such lighting shall not create a nuisance to abutting properties as a result of spillover. To the extent that the prescribed lighting is not diminished in effectiveness, all such lighting shall incorporate motion detectors, photocells or similar devices to activate the special light fixtures but shall be provided with a manual switching device to override the fixture when necessary.
