Martin Marietta employs 360 local residents, of whom 106 operate the Beckmann Quarry.


The aggregates, concrete and ready mix industry have an annual impact of $5 billion on the Texas economy. The Beckmann Quarry is one of the region’s oldest and largest active quarries and is a large contributor to the Texas economy.


San Antonio has a rich history of quarry redevelopment. After the quarry is fully mined out, an opportunity will exist to repurpose the land, as has been done with other parts of the Beckmann Quarry to form The Shops at La Cantera, The Rim Shopping Center and Six Flags Fiesta Texas. Other former quarries in San Antonio have been transformed into economic and tourism drivers such as the San Antonio Zoo, the Japanese Tea Gardens, Morgan’s Wonderland and The Alamo Quarry Market.
