VICKREY provided civil design and surveying services for this 477-acre, 1,149-lot subdivision located in north Bexar County over the Edwards Aquifer Recharge Zone, which included over 42,500 linear feet of arterial, collector and local roadways and a bridge-class culvert crossing of Elm Waterhole Creek consisting of sixteen 10’x10’ concrete boxes. The project also included over 47,100 feet of new 8-, 12-, and 16-inch water main, 40,200 feet of sanitary sewer main, and a new lift station. Rather than providing numerous small detention basins, the increase in stormwater runoff from the development was mitigated by excavating within the storage area of the downstream SCS Dam No. 12, thereby increasing its storage volume. The firm provided master planning, design, subdivision platting, construction administration and staking, as well as permitting & coordination with TCEQ and FEMA.
