Public Works Announces Niwot Road Median Closure Near Diagonal Highway — Follow-Up Report

Boulder County Public Works announces a temporary median closure on Niwot Road near the CO-119 Diagonal Highway intersection for utility infrastructure improvements. The closure will affect left turns from Niwot Road onto the Diagonal Highway for approximately six weeks. A signed detour route will be in place.

A community information session will be held at the Lafayette library on Thursday, April 16 at 6:00 PM. Translation services in Spanish and Nepali will be available. The session will also be livestreamed on the Boulder County YouTube channel.

Data from the 2024 Boulder County Community Survey shows that 56% of respondents rated this service as “important” or “very important.” The survey, conducted every two years, received 4,091 responses from residents across the county.

Next Steps

Environmental review of the project area near SH-7 / Ute Highway found 3 sensitive species and 2 wetland areas requiring mitigation. The Community Planning & Permitting worked with Colorado Parks and Wildlife to develop a habitat conservation plan.

Wildfire risk mapping conducted by Wildfire Partners shows that 29% of properties in the Lafayette area are within the wildland-urban interface. Free home assessments are available through the Wildfire Partners program, with rebates of up to $2,500 for mitigation improvements.

Community Impact

Eligible participants include Boulder County residents with household incomes at or below 60% of Area Median Income (AMI). For a family of four, this is approximately $95,000 per year. Applications are processed on a first-come, first-served basis.
