Army Corps of Engineers: Environmental Infrastructure Assistance [Updated February 27, 2020] [open pdf - 445KB]
From the Document: "The U.S. Army Corps of Engineers (USACE) undertakes water resources development projects pursuant to authorizing statutes and the receipt of appropriations. Traditional USACE projects for navigation, flood control, and ecosystem restoration are authorized in omnibus authorization bills often titled Water Resource Development Acts (WRDAs). Since 1992, Congress also has authorized and provided for USACE assistance with planning, design, and construction of municipal drinking water and wastewater infrastructure projects in designated communities, counties, and states. This assistance supports publicly owned and operated facilities, such as distribution and collection works, stormwater collection and recycled water distribution, and surface water protection and development projects. This USACE assistance is broadly labeled 'environmental infrastructure' (EI)."
