Fiscal Sustainability Preservation of shared revenues. The City’s budget includes revenue from a number of State sources; most importantly, shared revenues from state income, sales, and vehicle license taxes. Shared revenues make up approximately 30% of the City’s general fund. A diverse and sustainable revenue stream with predictable sources is critical for the City’s financial well-being. Surprise supports the protection and full disbursement of shared revenues and a diverse revenue portfolio based on sustainable, predictable revenue sources. Unfunded mandates. The City opposes unfunded state mandates placed on local jurisdictions and encourages the Legislature to evaluate the fiscal impact such mandates will have on communities prior to considering the issue.
