The purpose of this chapter is to provide a safe and pleasant nighttime environment for the public while preventing nuisances from unnecessary light intensity, direct glare and light trespass.

All new or expanded parking areas and all new or expanded multiple-family residential, office, commercial and industrial uses shall have lighting capable of providing adequate illumination for security and safety. Parking lot lighting shall be adequate to light the parking surfaced areas for security purposes from dusk until the termination of the business day. Building lighting shall be provided during the hours of darkness for all exterior doors, aisles, passageways and recesses.

Exterior lighting shall be shielded or recessed so that direct glare is confined, to the maximum extent feasible, within the boundaries of the site. Exterior lighting shall be directed downward and away from adjacent properties and public rights-of-way. Shielding means that the light source, whether bulb or tube, is not visible from an adjacent property or right-of-way.

Pole mounted lights shall not exceed 18 feet in height. Additional height may be allowed with an approved use permit.

All new construction for which parking lot lighting is required shall provide a lighting plan that details location, size, height, orientation, type of fixture and level of wattage of the outdoor lighting.

Lighting shall be coordinated with landscape plans to assure that tree growth will not interfere with the intended illumination.

All lighting systems and fixtures shall be maintained in good working order and in a manner that serves the original design intent of the system.
