Lowcountry-based design firm SeamonWhiteside (SW+) is looking to improve flooding issues on Sullivan’s Island. The group was selected for two projects, the Stormwater Master Plan and the Drainage Improvement Project.
The Stormwater Master Plan aims to support the town in enhancing long-term coastal resilience for at least the next 50 years.
The Drainage Improvement Project is a federally funded project awarded through the SC Rural Infrastructure Authority. SW+ will work with Terracon for environmental permitting and geotechnical engineering + GPA Professional Land Surveyors for site measurements.
The project will include the following:
- Upgrading existing pipes
- Installation of tide gates to improve capacity and prevent tidal flooding
- Stormwater treatment devices to improve water quality
- Techniques to promote natural drainage
The project is expected to get underway in 2025 and be finished by the end of 2026.
