§ 12.3. Public area lighting.

A.

Applicability. Lighting shall be provided throughout any non-residential or multi-family parking lot. Lights to illuminate parking lots shall not be attached to any building, except for the lighting of parking rows immediately adjacent to buildings. This requirement does not apply to home occupations.

B.

Adaptive control integration. Dimmers, timers, and use of occupancy motion sensors are permitted after hours of public access.

C.

Type and color. The lighting color temperature of new and replacement light fixtures shall not exceed 3,000 Kelvins.

D.

Height. Light poles shall have a maximum height of 20 feet when in or adjacent to an agricultural or residential zoning district. All other light poles shall have a maximum height of 25 feet. The maximum height shall be measured from the parking lot grade at the base of the pole to the top of the pole. No portion of any light fixture mounted on a light pole may extend more than one additional foot higher than the maximum light pole height.

E.

Illumination levels. Light levels on commercial sites shall meet the requirements in Table 12.3 for the developed portion of the site containing buildings, drives and parking lots.

1.

Sites are not subject to minimum lighting levels during closed hours.

2.

Table 12.3 shall not apply to ornamental street lighting, public street lights or driveway/intersection lighting necessary for pedestrian and traffic safety.

3.

The light level along a non-residential lot line may be increased to the parking lot maximum in cases where there are shared access/vehicular connections or the adjacent use is a similar use.

Location on Site	Minimum Footcandles	Maximum Footcandles
Parking Lots and Building Entrances	0.6 (at any point) 2.4 (average)	10.0

1.

Lighting plan showing light fixture locations, height, and type designations.

2.

Lighting equipment specifications and data sheets.

G.

Photometric plans. The zoning administrator or planning commission may require a photometric plan to ensure that the intent and requirements of this section are met. When required, a photometric plan with a lighting grid shall be prepared by a lighting professional. The photometric plan shall show horizontal luminance levels (footcandles) in a point-by-point format.
