Relating to a study by the Texas Water Development Board of the state environmental review process for certain projects eligible for financial assistance from the flood infrastructure fund and the implementation of streamlining procedures based on the results of the study.

HB 186 requires the Texas Water Development Board to study how to simplify the state environmental review process for flood control and drainage projects seeking funding from the state's flood infrastructure fund (under Water Code Chapter 15). The study must be completed by January 1, 2027, after which the Board must implement new internal procedures to streamline these reviews based on the findings. This bill directly affects projects eligible for flood infrastructure funding, aiming to reduce administrative delays without changing funding eligibility. The bill expires September 1, 2027, and is procedural in nature (focusing on study and process changes, not direct policy or funding).
