A low-lying coastal community, Savannah is experiencing an increased frequency of intense storm and flood events.  



The Smart Sea Level Sensors Project aims to install a network of 50-100 internet-enabled water level sensors across flood-vulnerable City of Savannah and Chatham County


This is the first project of its kind in the region, and our goal is to provide a template for expansions of this technology and community stakeholder framework to other areas of vulnerable coastline along the southeastern US.

City is one of the founding project partners along with GA Tech and Chatham Emergency Management Agency. The City’s role is to guide the larger project effort with a specific focus on community engagement including youth, neighborhood residents and other organizations. We host and maintain sensor infrastructure.



The sensor network will stretch from Interstate 95 to Tybee Island, capturing a wide range of tributary sizes, orientation, and building densities. The data collection will be complemented by a suite of modeling tools to inform flood risk and vulnerability. Taken together, the framework enables the assessment of short-and long-term coastal flooding risk and vulnerability that are required to inform planning for flood mitigation strategies.

This project continues to grow with additional partnerships and applications. Learn more at the project website:
