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.
