The City of Chanhassen has released an educational video series explaining its Pavement Management Plan to residents, detailing how the city maintains its 119 miles of roads serving 26,000 residents and 500 businesses.

The series covers the city's systematic approach to road maintenance, including field reviews conducted every three years across three geographical areas. The Engineering Department uses an Overall Condition Index (OCI) scoring system, similar to school grades, to evaluate road conditions and determine appropriate rehabilitation methods.

According to the educational materials, roads scoring 90 or higher require only minor maintenance, while scores between 80-90 indicate good condition needing basic repairs like crack sealing. Lower scores trigger more intensive interventions: 70-80 may require mill and overlay, 50-60 calls for either mill and overlay or full depth reclamation, and scores below 40 necessitate complete reconstruction.

The city's approach includes four main rehabilitation techniques. Seal coating extends road life by approximately seven years through applying oil and rock layers. Mill and overlay involves removing the top asphalt layer and replacing it, extending road life by 15 years. Full depth reclamation pulverizes existing asphalt and underlying gravel to create a recycled base, while reconstruction completely overhauls roads including drainage systems and potential widening.

City staff conduct annual analysis of road conditions and allocate funding accordingly, with projects moving through design phases from 30% to 100% completion. The process includes environmental review with agencies like the Minnesota Department of Natural Resources and watershed districts, plus community engagement through surveys and open houses during the 30-60% design phase.
