LOMA and LOMR-F in Hidalgo County, Texas
Hidalgo County borders the Rio Grande in the Lower Rio Grande Valley, where flat terrain and extensive agricultural drainage systems create widespread flood risk. The county relies on a network of drainage districts to manage stormwater, but heavy rainfall events can overwhelm these systems and inundate urban areas in McAllen and Edinburg. Tropical storms from the Gulf of Mexico periodically bring intense rainfall that exceeds drainage capacity.
