The hunt for a new FBI headquarters hit a milestone Wednesday when federal officials announced that they had received 35 proposals from developers and communities interesting in hosting the agency.

Private sector developers in the D.C. region are showing "significant interest" in building a new, consolidated facility for the agency, General Services Administration officials said of the responses.

The GSA did not release the details of the submissions, however.

The FBI is looking to move out of its current headquarters in the J. Edgar Hoover Building along Pennsylvania Avenue in the District.

Officials are expected to launch a more formal search for sites later this year, but are waiting for the House to approve the relocation and guidelines for the construction of a new facility.

A House transportation subcommittee planned to meet Wednesday to discus the relocation, but was forced to postpone because of the weather. The meeting hasn't yet been rescheduled.

Although the House has been mum on the move, their Senate counterparts have requested that the new complex be located within two miles of a Metro station, 2.5 miles of the Beltway and be between 40 and 55 acres.

In Virginia, a GSA-owned warehouse in Springfield is expected to be on the list of submissions, as are eight sites in Loudoun County and a pair of sites from Stafford and Prince William counties.

Prince George's County in Maryland is backing a site near the Greenbelt Metro Station, while lawmakers in the District are pushing a site at Poplar Point along the Anacostia River.
