Lights shall be provided to illuminate parking areas required by this chapter. Such lights shall be arranged in a manner not to shine unnecessarily on adjacent properties. Where parking areas are separated from the buildings they serve by a public street, the crosswalk serving the parking area and building shall be appropriately lighted with a nine thousand five hundred (9,500) lumen sodium vapor light with steel pole installed according to Vernal City standards. The Planning Commission may waive this requirement for a crosswalk light if a lighted crosswalk is within two hundred (200) feet of the parking lot. (PZSC § 03-12-015 (3))
