Community Notes
Located in Bexar County on the Edwards Aquifer recharge zone. A dispute with the Westover Place subdivision over tree removal during construction drew community attention in 2025. Microsoft and SAWS data show the company's San Antonio facilities consumed hundreds of millions of gallons of water in 2023–2024 during Stage 3 drought restrictions.
