March 2024: Public Works Announces Niwot Road Median Closure Near Diagonal Highway

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.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 39% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

A community information session will be held at the Lyons library on Sunday, May 31 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.

How to Participate

Environmental review of the project area near Coal Creek Canyon Road found 11 sensitive species and 1 wetland areas requiring mitigation. The Sheriff’s Office worked with Colorado Parks and Wildlife to develop a habitat conservation plan.

Eligible participants include Boulder County residents with household incomes at or below 30% of Area Median Income (AMI). For a family of four, this is approximately $74,000 per year. Applications are processed on a first-come, first-served basis.

Next Steps

The Board of County Commissioners will review progress on this initiative at their June 5 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

The program is modeled after similar successful initiatives in Larimer County and Jefferson County. Boulder County’s version includes additional provisions for wildfire mitigation, affordable housing, and environmental sustainability.
