(A) Residential, commercial and industrial districts.
(1) Poles shall be located at all intersections and spaced at a distance not exceeding 300 feet from one another along the street. Poles shall also be located at the ends of cul-de-sacs and curves in the roadway as required by the Village Engineer. Poles shall be set in the parkway a minimum of two feet clear distance from the back of curb. Where the distance between the sidewalk and the curb is such that this location is impractical or where the sidewalk is adjacent to the curb, the Village Engineer shall be consulted for an acceptable alternate location for the pole.
(2) Unless otherwise directed by the Village Engineer, the direction of the support arm shall be at right angles to the centerline of one of the intersecting streets at a four-legged intersection with location preference to the higher classification roadway, if applicable. At "T" intersections, a pole shall be provided on the centerline extended from the terminating street at the top of the "T" with the support arm extending toward the center of the intersection. In cul-de-sacs, light poles shall be placed in the center median or if no center median is to be constructed, at the end of the cul-de-sac along the centerline extended.
(B) Arterials and collector streets.
(1) Poles shall be located at all intersections and spaced such that the illumination meets the following criteria given in Tables 1 through 4 below:

TABLE 4. RECOMMENDATIONS FOR PARKING AREAS
TYPE OF AREA | AVERAGE MAINTAINED FOOT CANDLES (F.C.) |
Active entrances, security lighting, pedestrian or vehicular | 5.0 F.C. |
High activity parking | 3.6 F.C. |
Low activity or inactive entrances, building surrounds | 1.0 F.C. |
(2) The average maintained foot candles in the above table are recommended by the IESNA. Light levels represent illumination levels that attempt to provide safety, economy, security and also meet community expectations. The illumination level should be maintained at a minimum of 2.0 foot candles in a surface parking lot.
