McAllen, TX – RV


What Happened

In June 2018, a sudden severe storm dumped heavy rains on the mesas north of McAllen, TX, and swept into the tributaries to the Rio Grande River. This freak storm created flooding where not typically expected, as the affected homes were not in a typical flood plain.

What MDS Is Doing

In the fall of 2022, MDS volunteers will begin construction of a number of new homes in response to the flooding events. RV project volunteers will finish the homes begun in the fall.


The Rio Grande Valley is located in the southernmost tip of Texas on the northern bank of the Rio Grande River, which separates Mexico from the United States. This region’s population is one of the fastest growing in the United States. Two popular tourist destinations in the Rio Grande Valley are Santa Ana National Wildlife Refuge and the Port Isabel Lighthouse.
