On November 16, 2012, the county issued a Solicitation for Conceptual Proposals through the Public-Private Transportation Act of 1995 for Loudoun County Parking Facilities (SCP). With the SCP, the county seeks parking facilities that are available on opening day of revenue operations for Phase 2 of the Dulles Corridor Metrorail Project, which currently is estimated to be sometime in 2018. Loudoun County received three conceptual proposals as a result of the SCP. County staff presented the proposals to the Board of Supervisors at a public hearing on May 8, 2013. The item prepared for the hearing and the staff presentation are online:

The conceptual proposals being considered are online: (Please note that these are large files.)

  • Comstock Partners (PDF): This proposal is to design, construct and operate approximately 4,938 parking spaces and related facilities to support both the Route 772 and the Route 606 Metro Stations. The Comstock proposal has been developed to offer the County the option to pursue all three garages or to select one or two of the garage project options.
  • Trammell Crow Company and Route 606, LLC (PDF): This proposal is to design, construct and operate a parking garage with the capacity to accommodate 2,190 parking spaces, which includes 225 additional spaces. The concept proposal contemplates modifications to the garage design and location from the preliminary engineering plans and incorporates office and retail development on immediately adjacent property controlled by MWAA.
  • West Dulles Properties Part 1 and Part 2 (PDF): This proposal is to design, construct and operate a parking garage to accommodate 1,965 parking spaces. The West Dulles proposed concept moves the garage location one land bay to the east from the preliminary engineering location and includes potentially redesigning the existing transportation street network around the station location. This proposal also allows for additional commercial development on the adjacent property controlled by MWAA.

Loudoun County has until July 1, 2014, to make a decision on the construction of the parking garages.

On November 15, 2011, the Board of Supervisors approved a Memorandum of Agreement (MOA) outlining commitments pertaining to Phase 2 of the Dulles Corridor Metrorail Project between Loudoun County, the U.S Department of Transportation, the Washington Metropolitan Area Transit Association, Fairfax County, the Commonwealth of Virginia, and the Metropolitan Washington Airports Authority. Included in the MOA was a commitment from the county to use its best efforts to secure additional funding sources that will be sufficient to fund the cost of the design and construction of the parking facilities. In discussions leading up to the approval of the MOA, the Board’s support for securing additional funding for the parking facilities was based on the following:

  • The county would make a reasonable and best effort to assemble a financial option for the three parking facilities as defined above, thereby taking the cost of those facilities out of the project, and
  • The removal of the parking facilities from the project scope would be contingent upon either: (1) a private sector partner and/or the Commonwealth guaranteeing and backing the cost of the facilities; or, (2) an alternative financing option that would require no local tax funding support, as well as, [at that time], the realization of TIFIA financing.

As is there no additional tax increment financing (TIF) measures or Transportation Infrastructure Finance and Innovation Act (TIFIA) funding for the garages, the county is expected to pursue concession payments or a share in parking facility revenues.
