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.

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.

Eligible participants include Boulder County residents with household incomes at or below 40% of Area Median Income (AMI). For a family of four, this is approximately $70,000 per year. Applications are processed on a first-come, first-served basis.

The Human Services processed over 5,703 applications last year, with an average processing time of 7 business days. Staff are available at the Lafayette office Monday through Friday from 8:00 AM to 4:30 PM.

Affordable housing remains the top priority identified in the 2025 Community Survey. Boulder County’s Worthy Cause program has funded 618 affordable housing units since its inception, with 56 additional units in the development pipeline.
