Governor Greg Abbott Directs $230 Million for Rio Grande Valley Flood Mitigation and Canal Widening

MCALLEN, Texas — Governor Greg Abbott and Texas Water Development Board (TWDB) Chairman George Peyton announced on Monday the distribution of $230 million in state flood mitigation capital grants from the voter-approved Flood Infrastructure Fund (FIF) to construct regional stormwater detention basins, widen primary drainage conveyance ditches, and install computerized water control weirs across Hidalgo, Cameron, and Willacy Counties in the Rio Grande Valley.

The project addresses chronic regional drainage vulnerabilities in low-lying colonias and municipal subdivisions that experienced severe residential inundation during intense tropical depressions and severe spring convective thunderstorms.

Protecting 1.4 Million Rio Grande Valley Residents from Tropical Storm Flooding The Rio Grande Valley's flat coastal delta topography and clay soils require engineered regional drainage canals that convey stormwater toward the Laguna Madre and Gulf of Mexico, where undersized culverts historically created severe water backup in residential neighborhoods.

"The hardworking families and small businesses of the Rio Grande Valley have suffered devastating flood damage from severe storms for far too long," Governor Abbott said during an announcement at the Hidalgo County Drainage District headquarters in Edinburg. "This $230 million investment provides the permanent engineered drainage infrastructure needed to protect our communities, constructing massive stormwater detention reservoirs and widening canals so floodwaters drain quickly away from homes, schools, and businesses."

Regional Drainage Packages Funded The $230 million allocation finances:

• Raymondville Drain Expansion: $85 million to complete channel widening and lateral connections for the 65-mile regional drainage backbone.
• Hidalgo County Regional Detention Basins: $75 million for four 500-acre earthen stormwater detention reservoirs capturing runoff from McAllen, Mission, and Pharr.
• Cameron County Colonia Drainage Upgrades: $45 million for underground storm pipe networks and concrete box culverts in unserviced unincorporated communities.
• Automated SCADA Flap-Gates & Weirs: $25 million to install computerized water control gates preventing flood backflows.

County judges, municipal mayors, and colonia community leaders commended the state investment, highlighting that engineered drainage infrastructure protects residential property values and lowers insurance costs.
