A BILL TO BE ENTITLED
 
AN ACT
  relating to a study and report by the Upper Guadalupe River
  Authority of risks from and solutions to flooding.
         BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS:
         SECTION 1.  DEFINITIONS. In this Act:
               (1)  "Authority" means the Upper Guadalupe River
  Authority.
               (2)  "Board" means the Texas Water Development Board.
               (3)  "Regional flood plan" means the regional flood
  plan developed under Section 16.062, Water Code, for the flood
  planning region that includes the upper Guadalupe River basin.
               (4)  "Regional flood planning group" means the regional
  flood planning group designated under Section 16.062, Water Code,
  whose flood planning region includes the upper Guadalupe River
  basin.
         SECTION 2.  STUDY AND REPORT. (a) The authority, in
  consultation with the board, the Texas Department of
  Transportation, and the regional flood planning group, shall
  conduct a risk assessment and project feasibility study to:
               (1)  quantify the risk to life and property posed by
  flooding in the upper Guadalupe River basin;
               (2)  assess potential solutions to mitigate flood risks
  identified under Subdivision (1) of this subsection; and
               (3)  propose not more than eight projects that will
  help mitigate the flood risks identified under Subdivision (1) of
  this subsection.
         (b)  In quantifying the risk to life and property under
  Subsection (a)(1) of this section, the authority shall:
               (1)  collect and assess existing data, including the
  data collected in connection with the regional flood plan, any
  integrated flood risk management studies for the area, topographic
  data, existing locally developed models, structure inventories,
  and hydrologic analyses;
               (2)  update as appropriate the information collected
  under Subdivision (1) of this subsection by incorporating the July
  4, 2025, weather event; and
               (3)  develop hydraulic models for the major creeks and
  rivers within the upper Guadalupe River basin.
         (c)  In assessing potential solutions to mitigate flood
  risks under Subsection (a)(2) of this section, the authority shall:
               (1)  identify projects that reduce susceptibility to
  flooding, including off-river detention storage, on-river dams,
  improved evacuation routes, river channel modification, and
  improved or new storm drainage systems;
               (2)  develop a hydraulic model for each potential
  project to determine the effect of the project with respect to:
                     (A)  flood mitigation;
                     (B)  water supply;
                     (C)  groundwater recharge;
                     (D)  recreation; and
                     (E)  environmental impacts; and
               (3)  conduct community meetings to gather input and
  feedback from residents with respect to the projects.
         (d)  In proposing projects that may help mitigate the flood
  risks under Subsection (a)(3) of this section, the authority shall:
               (1)  determine the costs and benefits of each project;
               (2)  score and rank the projects based on community
  feedback and the costs and benefits of the projects; and
               (3)  to the extent possible, develop design documents
  for the highest-ranked projects to expedite the completion of those
  projects.
         (e)  Not later than January 1, 2027, the authority shall
  present to the board and the legislature a report that contains a
  summary of the study conducted under this Act and a description of
  the projects identified by the authority that would best mitigate
  flooding in the upper Guadalupe River basin.
         SECTION 3.  EXPIRATION. This Act expires January 1, 2028.
         SECTION 4.  EFFECTIVE DATE. This Act takes effect on the
  91st day after the last day of the legislative session.
