Transportation is vital to the economy and our daily lives. These road, highway, rail, and transit projects face a demanding array of overlapping and competing jurisdictional regulations, environmental concerns, stakeholder interests, and limited financial resources.

Projects involving coordination with transit districts, ports, regional ferry systems, railways, state transportation departments, and federal transportation administrations are multiphase efforts requiring specialized technical expertise. Our team develops tailored approaches to deliver technically sound products that get projects operational quickly and cost-effectively, no matter how small or large the project. We partner with clients to efficiently navigate the unique regulations and funding requirements facing transportation projects including Section 4(f), MAP-21, and the environmental and planning regulations of the Federal Highway Administration (FHWA) and Federal Transit Administration (FTA). We serve public and private clients, including city and county departments of public works and transportation, regional transportation authorities and transit agencies, state departments of transportation, the U.S. Department of Transportation, FHWA, FTA, Federal Railroad Administration, and other agencies engaged in facilitating the movement of goods and people.
