Castroville Construction Along the Medina River and U.S. 90

In Castroville’s historic district, some of the oldest homes sit close enough to the narrow streets for a passerby to see how they were built. Families from Alsace settled along the Medina River in 1844, and their builders worked in stone, timber and logs. Owners planning an addition can use the city’s historic district maps and building guide to see how a porch, roofline or setback fits the original block.

Along U.S. 90, Castroville’s commercial corridors connect the historic downtown with newer retail and service-oriented development toward the east side of town. Access to the highway and nearby FM 471 makes these areas important for businesses serving residents and travelers. For builders and property owners, storefront configuration, parking, utilities and roadway access all shape how commercial sites can be developed.

Castroville Municipal Airport has its own pattern of development just off U.S. 90. Aircraft share the city-owned property with land still used for farming, and a 5,001-foot runway serves the field. For a business that wants to build a hangar or put a light industrial shop near the runway, the city offers long-term ground leases. That arrangement lets a business build while the land stays in public hands.

The Medina River helps shape where and how Castroville grows. Land near the river brings floodplain considerations into planning decisions, while zoning and the reach of water and sewer infrastructure influence development throughout the city. Castroville publishes maps of these conditions, showing how its natural landscape and public utilities together affect the possibilities for residential and commercial construction.
