FLORENCE ?Kambrah Garland Rodriguez stood in the middle of 35 acres of grapevines on a recent afternoon and pointed west to a hill on the outskirts of Florence. That is where an asphalt plant and quarry is proposed to be built, said Rodriguez, one of the owners and partners in a winery called the Vineyard at Florence. The plant has drawn intense opposition from neighbors and officials who say it would use too much water and cause other wells in the area that draw from the Trinity Aquifer to run dry, including the well at the winery.
