Subdivision Road Maintenance

The Boulder County Comprehensive Plan (BCCP) provides guidance on gravel and paved roads accepted for maintenance in unincorporated Boulder County. The BCCP stipulates that funding for major repairs should be prioritized for the county’s arterial and collector roadways, and that funding of local access roads (aka “subdivision roads”) shall be the responsibility of those served by the road (property owners).

While the county does not conduct major repairs (full roadway resurfacing) on subdivision roads, our Road Maintenance crews still conduct operations on these roads, including: snow removal; pothole patching; clearing of ditches, culverts, and other drainage structures; replacement/repairs of sidewalks; and, roadway crack sealing and patching to maintain public safety.
