Planning and Engineering

Public Works Engineering works with the Community Planning & Permitting Department’s Development Review team on for property access (driveways) that intersect with county roads.



Subdivision Roads

The Boulder County Comprehensive Plan (BCCP) provides guidance on gravel and paved roads accepted for maintenance in unincorporated Boulder County. Per the BCCP, Boulder County Road Maintenance cannot conduct major repairs (full roadway resurfacing) on subdivision roads, which are called “Local Access Roadways.” Our crews still conduct maintenance operations on local access 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. Learn more about local access/subdivision roads.
