From the Plan and Project Review: "The National Capital Planning Commission (NCPC) reviews and approves plans and projects for federal and certain District of Columbia buildings and installations. Through planning, policymaking, and plan review, the NCPC defines and protects both federal interests and broader national interests in the region's development. These interests are wide-ranging and multi-faceted, from ensuring that government agencies and foreign missions have safe, well-served facilities to addressing multiple uses of parks and open spaces. The NCPC encourages forward looking outcomes that achieve shared federal and local interests, including efficient infrastructure, a thriving economy, sustainable and safe development patterns, and natural and cultural resource stewardship."
