Mobility Choice Blueprint

Mobility Choice Blueprint

The Mobility Choice Blueprint is a collaborative strategy to help the Denver metro region identify how to best prepare for and invest in the rapidly changing technology that is revolutionizing transportation mobility. A unique planning and funding partnership of CDOT, DRCOG, RTD and the Denver Metro Chamber is creating the Mobility Choice Blueprint – a coordinated strategic direction for the evolving mobility of the region related to walking, bicycling, driving, and transit. The 2030 Blueprint will analyze travel trends and technologies in the region, explore an evaluate various technologies and their implications for mobility, align transportation investments of multiple public agencies, and create new planning and implementation partnerships.

Subdivision Roads

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.
