Public Entity Experience — Redevelopment Authority of Prince George’s County, MD

  • Mr. Cooper is chairman of the Redevelopment Authority (RDA) of Prince George’s County, MD.  The RDA is the principal development and redevelopment agency in Maryland’s second largest jurisdiction.  Its mission is to develop mixed-income housing and mixed-use development in the county’s urban communities and transit centers.
  • As chairman, Mr. Cooper presides over the RDA’s board meetings and is responsible for signing land-disposition agreements.  He also works with the board and the agency’s executive director to (1) identify firms and negotiate with them to develop large infill development projects; (2) acquire, rehab, and sell blighted foreclosed homes to qualified buyers; and (3) participate in neighborhood-outreach programs in order to facilitate communication between citizens and government.
  • Since becoming chairman, the RDA has selected a half-dozen development partners for projects with a total development cost of over $185 million and has provided more than 250 loans worth more than $4 million for down-payment and closing-cost assistance to low-income families.  Mr. Cooper’s work has been spotlighted in the national urban affairs magazine Next City, and the RDA’s efforts have been highlighted in both print (e.g., Washington Post) and television media (e.g., WJLA-ABC News 7 – Washington, D.C.).
