Local ground conditions

San Antonio anchors the southern end of the Texas Blackland Prairie, which USDA describes as extending from north of Dallas south to San Antonio. Its signature soil, Houston Black, covers about 1.5 million acres and is recognized worldwide as the classic Vertisol because its highly expansive clays shrink and swell markedly with moisture changes. The official USDA series description reports 40 to 60 percent clay and dry-season cracks 0.5 to 4 inches wide, 12 inches or more deep, open 90 to 150 cumulative days in most years. The Texas Water Development Board documents the 2010-2014 statewide drought and widespread drought in 2022 that rivaled 2011 conditions.
