Project Description
Grass Valley’s East Main/Idaho-Maryland Roundabout is located at the intersection of two prominent urban roadways with one leg accessing State 20/49 Freeway. It was uniquely designed with one– and two-lane segments. The project has received a very positive response from the community.
The team of W-Trans and Coastland | DCCM completed the design for this project. Coastland | DCCM provided civil design; drainage analysis and design; utility mapping and coordination; right-of-way needs identification; pavement design; and assistance to the City in obtaining regulatory permits and approvals. One leg of the intersection provides access to SR 20, so the design was coordinated with and processed through Caltrans. Coastland | DCCM also assisted the City with supplemental inspection services during construction.
“Coastland has been a go-to firm for construction inspection services. Their staff constantly foresee issues before they happen, saving both time and tax payer money. Their in-the-trenches understanding – literally – of how to build projects and partner with contractors has been a benefit to our community.”
Hunter Young, City of San Rafael
