tax revenue. Sales-tax revenue may also increase, and jobs may be added, although these factors and their multipliers usually do not influence the structure of TIF. The routine yearly increases district-wide, along with any increase in site value from the public and private investment, generate an increase in tax revenues. This is the "tax increment." Tax increment financing dedicates tax increments within a certain defined district to finance the debt that is issued to pay for the project. TIF was designed to channel funding toward improvements in distressed, underdeveloped, or underutilized parts of a jurisdiction where development might otherwise not occur. TIF creates funding for public or private projects by borrowing against the future increase in these property-tax revenues. History Tax increment financing was first used in California in 1952 and there are currently thousands of TIF districts operating in the US, from small and mid-sized cities to large urban areas. As of 2008, California had over four hundred TIF districts with an aggregate of over $10 billion per year in revenues, over $28 billion of long-term debt, and over $674 billion of assessed land valuation. The state of California discontinued the use of TIF financing due to lawsuits in 2011, and enacted the California Fiscal Emergency Proclamation 2010, thereby ending the diversion of property tax revenues from public funding, including the use of TIFs for the funding of the nearly 400 redevelopment agencies in the state. The RDAs appealed that decision, though they were eventually eliminated in February 2012 after the passage of the 2011 state budget. However, in 2015, the California Community Revitalization and Investment Authority Act was made law, providing for the creation of Community Revitalization and Investment Authorities (CRIAs), funded by Tax-Increment Financing. The primary purposes of CRIAs are the development or preservation of affordable housing for low and moderate income households (a minimum of 25% of TIF funding must be placed in an affordable housing fund) and creation or upgrading of public infrastructure in economically disadvantaged areas as defined under the provisions of the law. Additionally, Enhanced Infrastructure Financing Districts (EIFDs) may be created and financed by TIFs in California. With the exception of Arizona, every state and the District of Columbia has enabled legislation for tax increment financing. Some states, such as Illinois, have used TIF for decades, but others have only recently embraced TIF. The state of Maine has a program named TIF;
