Texas legislation enacted in 2007 created transportation reinvestment zones (TRZs), an innovative tool that allows local governments to raise funds to help pay for transportation improvements using all or part of the incremental growth in property and sales taxes from a designated area around the project. Legislation passed after 2007 has made significant changes to the law, facilitating greater use of the tool by local governments and expanding the scope of possible incremental tax dedication to include local sales tax. This report: 1) identifies and summarizes the changes in the TRZ legislation that have been enacted since the law’s inception; 2) describes the advantages and limitations of this financing tool through lessons learned during the implementation of municipal and county TRZs; and 3) updates the 2008 TTI-developed modeling tool used to assist in the analysis of TRZ value capture potential.
