About Zip Code 78725
Zip code 78725 covers the Hornsby Bend area and portions of southeast Austin and unincorporated Travis County, located approximately 12 miles southeast of downtown Austin. The zip code extends east of Austin-Bergstrom International Airport along the Colorado River corridor, encompassing rural land, the Tesla Gigafactory Texas complex, and scattered residential development along FM 973 and SH-130. The area takes its name from Hornsby Bend, a large meander of the Colorado River where Reuben Hornsby established one of the first Anglo settlements in the Austin area in 1832. The terrain is flat Blackland Prairie with rich alluvial soils along the river bottom.
Residential real estate in 78725 is predominantly rural, with single-family homes on acreage tracts ranging from 2 to 50 or more acres. Prices range from $250K for older homes on smaller lots to $800K for updated properties on 10-plus acres with outbuildings and livestock facilities. Manufactured homes on private land are common, starting around $150K. New residential subdivision development has been limited due to floodplain restrictions along the Colorado River and the presence of the city's biosolids processing facility (Hornsby Bend Biosolids Management Plant). Land values have increased since Tesla's 2020 announcement of its Gigafactory, and speculative land purchases for potential future development have driven vacant acreage prices up significantly.
Students in 78725 attend Del Valle ISD, which serves approximately 11,811 students (2025-26) across 15 campuses. Elementary schools in the area include Hornsby-Dunlap Elementary and Popham Elementary. Del Valle Middle School covers 6th through 8th grade, and Del Valle High School serves 9th through 12th. The district offers dual-language programs, career and technical education pathways, and an early college high school program partnered with Austin Community College. Del Valle ISD's tax base has benefited significantly from the Tesla Gigafactory and other commercial development along SH-130.

The 78725 population consists primarily of longtime rural residents, agricultural landowners, and a growing number of workers employed at the Tesla Gigafactory and adjacent logistics facilities.
