Travis Buski, chief operations officer of the Nueces River Authority, told the Dimmit County Commissioners Court the authority had won a Texas Water Development Board grant to update flood‑plain mapping across the region and that most county maps are decades out of date.

Buski said the grant would remap the county at roughly 6‑inch resolution, produce watershed modeling, support a regional early‑warning system and inspect high‑hazard dams. He told the court that about 993 residents currently live inside the 100‑year floodplain and that more accurate maps would help local road and infrastructure planning.

The total program award discussed was about $30,000,000; Buski said the county share under the 75% grant/25% match formula would be about $382,000. He said the River Authority can offer a 10‑year, zero‑interest loan to spread that local match into roughly $38,000 annual payments to the authority. "We only had two counties opt out so far," Buski said, describing the project as optional for each county.

Commissioners pressed for specifics: whether the program would include county roads and private roads in GIS layers, how the modeling would affect roadway design, whether nonparticipating counties would still see river‑flow mapping, and which agencies would carry out dam repairs. Buski said the Army Corps of Engineers and the Land Office would handle any required dam repairs; the River Authority would deliver inspections and modeling data that state agencies would then use for permitting and project design.

After questions about the local payment, map exhibits that referenced a different county in one draft, and how participation would affect eligibility for state funding, Commissioner Delacova moved to table the interlocal agreement to allow staff time for corrections and additional review. The motion passed.

Next steps the court identified: staff will ask the River Authority for corrected local exhibits naming Dimmit County, a clearer written explanation of the loan repayment option and a timeline for a January decision if the county chooses to participate in spring 2026 work.
