Broomfield, CO Outdoor Lighting: Light Trespass & Shielding (2026)

The Interchange Influence Area overlay covers land mapped around Broomfield's freeway and arterial interchanges along US-36, including the Interlocken and Flatiron Crossing corridor, and its development requirements under section 17-29-050 apply on top of whatever the underlying zone district already requires. Subsection (K), Lighting, is a two-part rule: clause (1) bars exterior lighting that creates glare or spillover light onto adjacent properties, and clause (2) caps walkway lighting at sixteen feet in height. These sit alongside the same section's other site-design rules, including a forty-foot building height cap under (F) and a requirement under (G) that parking lots over 100 spaces be broken into smaller, screened sections.

Because these are development-plan standards rather than a stand-alone nuisance ordinance, they are checked by the city's Community Development department when a project inside the overlay submits its site development plan or PUD plan, and again at building permit review; a lighting or photometric plan that shows glare crossing a property line is grounds to require redesign before approval. There is no separate variance track named in this section; a property owner seeking relief would need site development plan approval that documents equivalent screening or mitigation.

The rule reads narrowly, its wording is a printing artifact of the code itself ('Exterior .....lighting') rather than a substantive gap, but the operative command is unambiguous: no glare or spillover onto neighboring parcels, and low walkway fixtures.
