Agencies of the Federal Government responsible for public developments and projects shall cooperate and correlate their efforts by using the National Capital Planning Commission as the central planning agency for federal activities in the National Capital region. To aid the Commission in carrying out this function, federal and District of Columbia governmental agencies on request of the Commission shall furnish plans, data, and records the Commission requires. The Commission on request shall furnish related plans, data, and records to federal and District of Columbia governmental agencies.

To ensure the comprehensive planning and orderly development of the National Capital, a federal or District of Columbia agency, before preparing construction plans the agency originates for proposed developments and projects or before making a commitment to acquire land, to be paid for at least in part from federal or District amounts, shall advise and consult with the Commission as the agency prepares plans and programs in preliminary and successive stages that affect the plan and development of the National Capital. After receiving the plans, maps, and data, the Commission promptly shall make a preliminary report and recommendations to the agency. If the agency, after considering the report and recommendations of the Commission, does not agree, it shall advise the Commission and provide the reasons why it does not agree. The Commission then shall submit a final report. After consultation and suitable consideration of the views of the Commission, the agency may proceed to take action in accordance with its legal responsibilities and authority.
