Carolina Mederos, co-chair of the firm’s Transportation, Infrastructure and Local Government Practice, counsels corporations, trade associations and local governments on congressional and executive branch policy, legislative and regulatory matters, with an emphasis on creative federal funding and infrastructure development. She has obtained billions of dollars for the firm’s major transportation, water and local government clients through authorizing legislation, appropriations, grants and innovative financing and has expanded market opportunities for private sector clients.

Carolina’s substantive, comprehensive and creative strategies have consistently increased federal funding for public agency and local government clients in highways, transit, aviation, water, wastewater, economic development, urban revitalization, housing, law enforcement, health, historic preservation and other areas. To achieve maximum benefit for clients, she has developed and proposed new programs, changes in eligibility requirements and funding formulas and succeeded in getting them enacted into law.

She regularly assists major domestic and international corporations in removing outmoded and costly legislative, regulatory and policy barriers, expanding market access and increasing competition. She secured legislative and policy incentives promoting innovative project delivery and advanced technologies, saving time and money in transportation projects and creating market opportunities. She resolves complex Buy America, hazardous materials, motor carrier, rail, pipeline, maritime and vehicle safety legislative, regulatory and compliance issues in Congress and at the US Department of Transportation (DOT).

Carolina’s strong knowledge of transportation, infrastructure and federal funding issues is a direct result of having been involved in the development of every surface transportation and aviation reauthorization proposal and DOT appropriations act over the last 30 years. Previously, Carolina served for more than 13 years in senior positions in the Office of the Secretary of DOT, including as deputy assistant secretary for Safety and as deputy assistant secretary for Policy and International Affairs. She also served as director of Programs and Evaluation, where she was responsible for developing and defending the entire Department’s authorizing and appropriations legislation before the Office of Management and Budget and Congress.
