Most of the “Colonia” and “Addition” names on the list are small rural subdivisions platted without water or sewer service, a pattern common across South Texas border counties and tracked separately by the Texas Water Development Board.<\/p>\n ZIP Codes<\/h2>\nThe colonias and rural crossroads communities have no ZIP code of their own; mail there is addressed to whichever of the five post office towns is closest.<\/p>\n Geography<\/h2>\nDuval County lies in the brush country of South Texas, a flat to gently rolling landscape of mesquite, huisache, and cactus rangeland used mostly for cattle ranching and, since the 1930s, oil and gas production. The county has little surface water; the San Diego Creek and several intermittent draws cross it, and the Piedras Pintas salt dome in the county’s north is under evaluation for underground hydrogen storage.<\/p>\n Duval County borders McMullen County<\/a> to the north, Live Oak County<\/a> to the northeast, Jim Wells County<\/a> to the east, Brooks County<\/a> to the southeast, Jim Hogg County<\/a> to the south, Webb County<\/a> to the west, and La Salle County<\/a> to the northwest.<\/p>\n Duval County had 9,831 residents at the 2020 census, giving a density of about 5.5 people per square mile — one of the more sparsely populated counties in South Texas. San Diego, the seat, and Freer, its second-largest city, together account for most of the county’s population; the rest live across small unincorporated communities and colonias. Household income in Duval County runs well below the Texas median of $75,780, consistent with other rural counties in the brush country.<\/p>\n Oil and gas has driven the county’s economy since the discovery of the Piedras Pintas field in the 1930s, and Freer still markets itself as the “Rattlesnake Capital of Texas,” home to an annual Rattlesnake Round-Up. Cattle ranching remains the other major land use across the county’s rangeland. San Diego, the county seat, hosts county government offices and the Duval County Courthouse.<\/p>\n Duval County was created from Live Oak, Nueces, and Starr counties in 1858 and organized in 1876. It is named for Burr H. Duval, a soldier in the Texas Revolution who was killed in the 1836 Goliad Massacre. In the mid-20th century the county was the base of the Parr family political machine, whose control of local elections drew national attention, including a disputed 1948 U.S. Senate ballot count that helped elect Lyndon B. Johnson.<\/p>\n U.S. Highway 59 crosses the county through Freer and San Diego, with Interstate 69W under construction along the same corridor; State Highways 16, 44, 285, and 339 connect the smaller communities.<\/p>\n The nearest commercial airport is Corpus Christi International Airport.<\/p>\n Where is Duval County, Texas?<\/strong> What is the population of Duval County?<\/strong> How big is Duval County?<\/strong> What is the county seat of Duval County?<\/strong> How many towns are in Duval County?<\/strong> |
