Tax Increment Reinvestment Zone

Tax Increment Reinvestment Zones (TIRZs) are special zones created by City Council to attract new investment in an area. TIRZs help finance costs of redevelopment and encourage development in areas that would otherwise not attract sufficient market development in a timely manner. Taxes attributable to new improvements (tax increments) are set-aside in a fund to finance public improvements within the boundaries of the zone.
