A 1,700-acre open-pit limestone quarry threatens the Edwards Aquifer, our air, our roads and our way of life between Bulverde, Garden Ridge and New Braunfels. We are families, ranchers, teachers and veterans saying NO to Vulcan Materials.
Stop Vulcan Comal County Quarry is a volunteer-led coalition of 15,000+ residents, landowners, parents and small businesses. We formed when Vulcan Materials quietly secured land for a massive open-pit mine on FM 1863 between Bulverde and New Braunfels — over the Edwards Aquifer Recharge Zone, next to neighborhoods, schools and historic springs.
We are not against responsible growth. We are against a 100-year, 24/7 blasting operation that will crack foundations, drain wells, fill classrooms with silica dust and send hundreds of rock trucks through our two-lane country roads. Our mission: stop the quarry through science, law, and people power.
Limestone quarries are not just holes in the ground. They fracture karst aquifers, release crystalline silica, lower property values up to 30% within 3 miles, and operate for 75-100 years. Here's what Vulcan's plan means for Comal County.
Deep blast pit — below aquifer level. Risk of dewatering wells and contaminating drinking water with nitrates, diesel and sediment.
Silica dust clouds travel 5+ miles. Linked to asthma, silicosis, heart disease. Elementary schools in blast zone.
Average home value loss near open-pit mines. $400M+ in collective equity at risk for 8,000 homes.
Blasting, crushing, trucking noise 55-85 dB. Cracked slabs, broken windows, stressed livestock and wildlife.

Our drinking water flows through porous limestone caves. Quarry blasting opens direct channels for pollutants to reach San Antonio and New Braunfels springs. Once contaminated, it cannot be cleaned.

Johnson Ranch, Copper Ridge, Garden Ridge, Bulverde villages — all within dust and blast vibration radius. Kids with asthma already report worse days when test drilling occurs.
Quarry dewatering pumps millions of gallons daily, lowering neighboring wells by 50-200 ft. During Texas droughts, wells go dry first.
Crushing limestone releases respirable crystalline silica — a known carcinogen. TCEQ monitoring is sparse and self-reported.
Daily blasts cause seismic vibrations, flyrock, cracked foundations and PTSD for veterans, seniors and animals.
500+ heavy trucks daily on FM 1863, SH 46 and US 281 — roads built for ranch traffic, not 80,000-lb loads. Fatalities will rise.
Golden-cheeked warbler, karst invertebrates, bats and Guadalupe bass depend on intact Hill Country. Quarries destroy habitat forever.
German-Texan homesteads since 1840s, wineries, wedding venues and tourism — $120M local economy threatened by industrial scar.
Legal filings, water data, town hall recaps and how to help — straight from volunteers, geologists and attorneys.

Historic turnout forces extended comment period.

Approximately 1,700 acres on FM 1863 between Bulverde / Garden Ridge and New Braunfels, Comal County. Directly over Edwards Aquifer Recharge Zone, within 2-3 miles of dozens of subdivisions and schools.
Yes. Limestone transmits vibration far. Homeowners near existing Texas quarries report cracked slabs, drywall, pool leaks and well siltation within 3-5 miles. Get a pre-blast survey and water test now — we offer free referrals.
Vulcan promises ~50-80 jobs, mostly transferred. Tourism, wineries, construction and ranching employ 4,000+ locally and depend on clean hills and water. Net economic impact is deeply negative.

No. Republicans, Democrats, independents — ranchers and newcomers — stand together. Clean water and safe kids are Texas values.
