Fiscal impact analysis measures the cash flows to and from the public sector by comparing alternative development scenarios and analyzing the ramifications of development proposals. It determines if revenues generated by new growth cover increased service and facility demands. While it does not directly calculate economic impacts, fiscal impact analysis provides facts about long-term fiscal health to help communities make sustainable land use decisions. Models can estimate revenues like property, income, and sales taxes as well as costs to public services from new development. Challenges include availability and compatibility of local data across jurisdictions and ensuring usability for non-expert users.
