San Benito backs regional RGV flood-control district after stormwater presentation; experts warn forecasting needs more funding

San Benito commissioners voted 3-2 on April 15, 2025, to approve a resolution supporting creation of a regional Rio Grande Valley (RGV) flood-control district, an action proponents say is a first step toward coordinated, watershed-based flood management across Cameron, Hidalgo and Willacy counties.

The vote followed a presentation by representatives of the regional stormwater task force and the group that operates a sensor network across the valley, who described a 61-station monitoring system that includes three sensors funded and sited inside San Benito. Presenters and several residents who described repeated home flooding urged the commission to support a single regional entity to prioritize projects by watershed rather than by political boundaries.

The stormwater task force presentation matters because it tied recent, severe flooding to gaps in forecasting and management and mapped an approach to give officials and residents earlier, more actionable warnings. Proponents said the combination of sensor data, hydrologic models and additional funding could enable the valley to move from post‑event analysis to multi‑hour forecasting and targeted mitigation.

Dr. Andrew Ernest, a representative of the regional stormwater task force, told the commission the sensor network and modeling work represent “the culmination of this” regional effort…
