The National Park Service develops a budget each February for the next fiscal year (FY), which starts October 1. Our budget—published in what we call the Green Book—defines our goals and objectives and the funding necessary to accomplish them. The National Park Service budget is rolled up into the budget for the Department of the Interior and then with the rest of the Executive Branch and submitted to Congress for its review and approval.
