Full Breakdown
Sec.

Division 6 applies to new development, redevelopment, and expansions or alterations of fifty percent or more of a building's floor area under Sec. 25-154(a), subject to exemptions in Sec.
0 footcandles at an adjoining residential lot line. Fixture design rules in Sec. 25-156 reinforce the trespass cap by requiring full cut-off fixtures directed downward, capping fixture height at twenty feet in residential districts and twenty-five feet elsewhere, and limiting decorative uplighting to 1,600 lumens per fixture. Review of these standards ties to the underlying development, permit, or building-permit application under Sec. 25-155. The division was adopted by Ord. No. 9572, § 2, effective December 17, 2024.
Violations & Fines
