Compound Flood Resilience Planning in Coastal Georgia

Project Overview

This project aims to identify and characterize coastal inundation risk, which is compounded with contamination risk from point and non-point sources of pollution.

The team will look at current and future inundation risks using simulated storms, map contamination risks from point (Superfund sites) and non-point (septic tanks) sources and estimate the economic impact to the properties and structures at risk.

The Challenge

Point sources produce pollution from a single place, such as a drainage pipe or wastewater treatment plant. Non-point sources produce pollution across a wide area, such as runoff from a city street or from septic tanks during a storm. With every flood, Brunswick faces increased pollution risk from both types of sources. Glynn County houses 15 active Superfund sites, four of which are on the National Priorities List (NPL), and 8 archived sites. The EPA designates Superfund sites for containing hazardous substances. Additionally, over 12,000 houses in Glynn County are not connected to sewers but rely on aging septic systems.
