Capital Improvement Program
Included in the annual budget is an updated Capital Improvement Program (CIP), which is a plan summarizing all major capital expenditures over the next five years. The plan provides the structure for the City to plan future projects. The CIP includes a description of each approved project, along with detailed financial requirements and financing sources. A project qualifies for inclusion in the CIP if it meets the following criteria:
- Has a minimum value of $50,000;
- Has a multiple-year useful life; and
- Results in a fixed asset.
The budget development process is extensive and in-depth and includes a series of discussions between staff and the City Council. Discussions are structured as public workshops and review the proposed revenues and expenditures for the budget year. Additionally, workshops address operating and capital improvement budgets across all City funds and departments.

Principle 1 – The City will pass a structurally balanced operating budget annually
Principle 2 – The City commits to continuous improvement in the delivery of necessary and cost-effective services
Principle 3 – The City will actively seek to increase its reserves to 25 percent and reduce its debt by 25 percent in the next eight years
