Washington, DC (December 5, 2007)- The U.S. Environmental Protection Agency (EPA) has signed an agreement with the District of Columbia to implement major green infrastructure enhancements to protect the Potomac and Anacostia rivers from storm-water runoff.
In modifications to a Clean Water Act permit, the district has agreed to undertake measures to stem storm-water flow and pollution, using natural systems such as trees, green roofs, and vegetated buffers.
Highlights of the new measures include:
* Creating a tax-incentive plan for the installation of green roofs.
* Requiring all new district-owned buildings and, where feasible, all major renovations of district-owned buildings to include green roofs.
* Planting and maintaining at least 13,500 additional trees.
* Devising a low-impact development plan that will include converting paved areas, such as median strips and large sidewalks, into green space
* Implementing enhanced programs for street sweeping and trash removal
* Installing 50 rain gardens and 125 rain barrels.
