Where Is the Planned Vulcan Comal Quarry?

Vulcan Materials plans to set up a 1500-acre open-pit limestone quarry in a residential area of central Comal County, located between Bulverde, Spring Branch, Garden Ridge, and New Braunfels.


  • Nearly three miles across
  • One mile fronting SH 46
  • 1½ miles fronting FM 3009
  • Less than one mile from FM 1863
  • ¼ mile from Beck Road

Carcinogenic Dust

All gravel quarries create and emit dust particles strongly associated with health problems such as lung cancer,1 heart disease,2 stroke,3 and reproductive issues.4 The finest particles are invisible and affect residents living miles away from the actual quarry site.

Truck Traffic

With the additional gravel-hauling traffic, expect to see an estimated 444 truck loads per hour in the surrounding area. The increased truck traffic will make our roads more dangerous and lengthen travel times. Roadways most impacted will be SH 46, FM 3009, FM 1863, and Beck Road.

Property Values

According to studies, properties within a five-mile radius of a new quarry lose up to 20 percent of their market value.5,6 Over 12,000 people live in the surrounding area. Property valuation losses are estimated at over $100 million.

Water Resources

The Vulcan quarry will affect local wells, water levels, and water quality. Impact will come from blasting, destruction of caves, increased storm runoff, and hazardous chemicals entering the water supply.
