The city budget serves a number of functions. At the most basic level, it is a legal document that gives city officials the authority to incur obligations and pay expenses. It allocates resources among departments, reflecting the legislative body’s priorities and policies, and controls how much each department may spend. The budget includes mission statements, goals, and objectives that convey to the citizens the vision for the future of the municipality’s elected officials. The budget also serves an evaluation tool, comparing commitments made in the previous year’s budget with actual accomplishments.
