Prince George's County officially endorsed Greenbelt as the FBI landing site Tuesday in a letter to the U.S. General Services Administration.

The letter, signed by County Executive Rushern Baker and County Council Chairwoman Andrea Harrison, extols the virtues of the location's transportation access and development opportunities. (Read the complete letter in the embedded viewer below this story.)

"The Greenbelt Metro Station is one of the few locations in the National Capital Region that can meet all the real estate, logistical and security needs of a new FBI headquarters," the letter reads. "You can be confident that Prince George's County will provide an expedited, streamlined, review process and, with our federal, state, and private partners, a commitment to provide all necessary infrastructure to make FBI location here an indisputable success."

The site is also near a federal courthouse.

The county is going up against Virginia and D.C. The former has proposed seven sites, including a federally owned warehouse in Springfield, while the latter is pitching Poplar Point, a site on Anacostia River currently used by the U.S. National Park Service and the U.S. Park Police.

The new location must be within two miles of a Metro station, within 2.5 miles of the Capital Beltway and between 40 and 55 acres, according to U.S. Senate requirements.
