Article 12 requires non-residential exterior lighting to use cutoff fixtures. Lighting must be a no-cutoff, total-cutoff up to 90 degrees, or total-cutoff at less than 90 degrees type, and non-residential projects must submit a lighting plan.
The Zoning Ordinance's Exterior Lighting article (Article 12) controls glare and light spill. Exterior lighting must be one of three fixture types: no cutoff, total cutoff up to 90 degrees, or total cutoff of light at an angle less than 90 degrees, each meeting its own fixture standards. All non-residential development must submit a lighting plan (prepared by a certified architect, landscape architect or lighting designer) showing fixture locations, foot-candles on a 10' x 10' grid, pole heights, fixture type, cut-off and projected angle. Flickering or flashing lights are prohibited, and public street lighting is exempt. These are not formal International Dark-Sky ordinance standards but function to limit upward and off-site light.
Lighting that fails the cutoff standards or lacks an approved plan is enforced through the site-plan and building-permit process by Polk County Planning & Development.
