Relating to the use of green stormwater infrastructure in new state buildings.

SB 526 requires Texas state agencies to use green stormwater infrastructure - such as rain gardens, permeable pavement, and bioswales - in the construction of all new state buildings, including projects previously exempt from certain building regulations. The law mandates these features to absorb rainwater, reduce flooding risks, and protect water quality by managing runoff. It applies only to new building projects where bidding or solicitation begins on or after September 1, 2025, leaving pre-existing projects unaffected. This policy change directly affects state agencies planning new construction, altering their standard building requirements.
