The U.S Army Corps unveiled a $1.7-billion, 10-year plan this week to restore the ailing Anacostia River in the Washington, D.C. metropolitan area to health.

The plan, two years in the making, identifies 3,000 projects to help restore the severely polluted river and watershed spanning 176 sq miles of land through a combination of stormwater controls, stream restoration, wetland creation and restoration, fish blockage removal, reforestation and controlling trash and chemical contamination
