AES provided a number of critical engineering services for Sentara Healthcare System’s Williamsburg Regional Medical Center campus, which is located in York County. The 80-acre campus includes a 97,000 sq. ft. outpatient care facility, a 145-bed hospital, a 596-space parking lot, a sanitary sewer pumping station, and a helipad. Addressing significant environmental challenges, AES produced a Stormwater Master Plan, ensuring the stormwater treatment facilities exceeded all local standards.
