Emergency Crime Scene and Biohazard Cleanup in Alamo, TX

Alamo was laid out in 1909 by the Alamo Land and Sugar Company, which moved the earlier settlement of Camp Ebenezer to higher, better-drained ground nearby.

Alamo is named for the famous Alamo Mission in San Antonio, a name chosen by the townsite company that promoted the new town to settlers.

Alamo was incorporated on May 12, 1924, and grew steadily from just 200 residents in 1925 to 1,018 residents and fifty businesses by 1936.

Before the town existed, land speculators Peter Ebenezer Blalock and George T. Hawkins accumulated some 32,000 acres of land around the future townsite between 1902 and 1909.

Alamo sits in the irrigated farming belt of southern Hidalgo County, and during the 1940s and 1950s it served mainly as a shipping point for the Rio Grande Valley's vegetables and citrus fruit.

Alamo had 19,493 residents in the 2020 census, up from 18,353 in 2010, and its population was estimated at about 20,625 by mid-2025.

Alamo has about 6,032 households, roughly 74% of its homes are owner-occupied, and households average about 3.35 people — well above the national average.

Alamo is the gateway to the Santa Ana National Wildlife Refuge, about 2,088 acres of subtropical thorn forest along the Rio Grande where more than 400 bird species have been recorded.

Alamo is a popular winter resort and retirement town, drawing seasonal "Winter Texan" residents to the Rio Grande Valley each year.

Alamo is one of the Valley's gateways to Mexico, with U.S. Route 281 leading south to the border crossing at Nuevo Progreso, Tamaulipas.
