Low Battery Seawall Repair
The Low Battery Seawall was originally constructed in the early 20th Century. After protecting the City of Charleston for over 100 years, it was in need of significant repairs. Gulf Stream Construction commenced construction of the Low Battery Seawall Repairs in December 2019 and has since completed Phases 1, 2, and 3. The fourth and final phase is currently under construction and on schedule to be complete in April 2025. The total length of the Low Battery Seawall being replaced spans nearly 5,000 ft, and the wall height is being raised nearly 2’ to match the height of the High Battery and better protect the City against rising tides and storm surge.
Scope of Work:
- Demolition of the existing seawall, timber pile extraction.
- Construction of a new foundation to support the new seawall, micro-pile installation.
- Replacement of the seawall, raising it nearly 2’ and providing a 10’ promenade for pedestrians.
- Replacement of water and sewer utility mains and services.
- Replacement and upsizing of storm drainage to provide increased capacity for conveyance, and installation of check valves at the outfalls to prevent the drainage system from being inundated with tidal influence.
- Installation of water quality treatment devices to treat stormwater prior to discharging to the Ashley River.
- Installation of traffic calming tables at the intersections along Murray Boulevard.
- Installation of ADA compliant ramps, improved walkways, and sidewalks.
- Replacement of palm trees and landscaping installation.
