WASHINGTON (AP) -- A new report from the U.S. Army Corps of Engineers says improving the Anacostia River can start with more than 100 projects to revive Sligo Creek and its watershed.
The 11-square mile area is the source of rainwater, sediment and trash that eventually ends up in the Anacostia.
The report calls for erosion controls, green roofs and weekly street sweeping.
The corps is planning similar restoration blueprints over the Anacostia's 22 other tributaries. The report says the Anacostia Restoration Plan will require several decades, two billion to three billion dollars and the cooperation of federal, local and Maryland authorities.
The Sligo Creek watershed spans Montgomery and Prince George's counties and D.C.
