Grosser Airport

The primary reason for the closure was suburban real estate development. The land, located in the rapidly growing area of Bulverde north of San Antonio, became more valuable for residential housing than for use as a private airfield. This is a common reason for the closure of small, privately-owned airports located near expanding metropolitan areas.

The site of the former airport has been completely redeveloped into a residential housing subdivision. The main road through the development is named 'Grosser Creek', a direct reference to the former airport's owners. The faint outline of the former runway is still partially visible on satellite imagery, running through several large residential lots and underneath the main road. The land is now occupied by single-family homes, roads, and related infrastructure.

Grosser Airport, also known as Grosser Field, was a private-use general aviation airport. It was established sometime before 1970 and was owned by the Grosser family. The airport featured a single unpaved turf runway, approximately 2,600 feet in length, with a north-northwest/south-southeast orientation (roughly runway 16/34). It served as a base for personal and recreational flying for its owners and likely other local pilots. Its historical significance lies in it being a typical example of the numerous family-owned, rural airstrips that were common throughout Texas before being overtaken by urban sprawl. The identifier 'US-10478' is a non-official code from a third-party database; it was not an official ICAO or FAA identifier.

There are no plans or prospects for reopening Grosser Airport. The land has been permanently repurposed for residential use. The original runway area is now obstructed by numerous houses, private property lines, trees, and roads, making any future aviation operations impossible. Reacquiring and clearing the land would be legally and financially prohibitive.
