EPA Administrator Gina McCarthy and Maryland Gov. Martin O'Malley said they would work through a joint investment of $3.4 million on a green cities initiative.
The EPA said the program, administered with the support of the Chesapeake Bay Trust, was part of Washington's efforts to use more green infrastructure and add more green space to the region.
"EPA's expanded partnership with the state of Maryland and the Chesapeake Bay Trust will support projects to improve water quality and economic vitality in the region," McCarthy said in a statement Wednesday.
Maryland Sen. Ben Cardin, the Democratic chairman of the Senate Environment and Public Works Water Subcommitee, said stormwater runoff was one of the greatest environmental threats to the Chesapeake Bay.
"We can build our roads and cities to include permeable materials, non-structural alternatives, and other green infrastructure solutions [with the funding]," he said in a statement.
