The District has asked the FBI to consider moving to Poplar Point, a massive site in Southeast Washington, as it weighs relocating from its longtime headquarters on Pennsylvania Avenue.

D.C. Mayor Vincent Gray's administration said Tuesday that it submitted its plan to the federal government's General Services Administration on Monday.

"In Poplar Point, the District of Columbia offers a prime real-estate location that presents the GSA with an opportunity to recommit to the District, our nation's capital," Gray said in a statement. "Here, the federal government has the opportunity [to] build a new facility tailored to the needs of the FBI on an accessible parcel with ample space to meet the federal agency's square footage, parking, security and sustainability requirements."

The city's submission on Monday was a formality: District officials acknowledged last month that D.C. would pitch Poplar Point as the FBI contemplates a move.

Jurisdictions in Maryland and Virginia are also competing for the opportunity to house the nation's most prolific law enforcement agency and its 12,000 workers.
