• The project addressed the station’s history of flooding by raising critical operating areas and equipment above the established flood elevation.
• JCC demolished the existing pumping-station superstructure and modified the remaining foundation and wet-well structure to support the upgraded facility.
• The company extended the existing foundation walls and constructed a new elevated floor slab with a finished-floor elevation of approximately 8.21 feet.
• Johnston Construction Company completed the 2nd Street Wastewater Pumping Station Improvements project for the Town of Ocean City, Maryland.
