Flood risk and mitigation

Georgia

Overview

Floods and hurricanes are a serious threat to Georgia, causing loss of life and considerable physical and economic damage to communities. Between 2000 and 2017, nine federal disasters were declared for floods, hurricanes, and tropical storms in the state, costing the U.S. government millions in assistance.1

Federal flood insurance helps communities prepare

In Georgia, 53 localities participate in the National Flood Insurance Program’s Community Rating System. This voluntary program offers communities lower insurance premiums if they have flood plain management practices that exceed the program’s minimum requirements. These practices include buying out flood-prone homes, improving storm drainage, elevating buildings, and floodproofing structures. Chatham County and the cities of Griffin and Savannah have taken advantage of this program and earned a Community Rating System designation of 5, the highest in the state. This has  garnered policyholders living in a designated flood zone a 25 percent discount on flood insurance premiums.2

Mitigation pays in Georgia 

The National Institute of Building Sciences recently found that investment in mitigation, including through programs like the Federal Emergency Management Agency’s Pre-Disaster Mitigation Program and Hazard Mitigation Grant Program, saves society $6 for every $1 spent. In the most flood-prone parts of Georgia, building 2 feet higher than the code requirement returns $6.70 for every $1 invested.3

Importance of policy 

Communities must take action to better prepare for weather-related catastrophes such as floods. And federal officials should consider policy reforms that would improve flood protection and preparation, minimize disruptions to the economy, and reduce costs to federal and state taxpayers. These actions include:

  • Increasing federal investment in flood mitigation programs that help communities prepare for and reduce the damage from floods.
  • Improving resilience requirements for infrastructure built and rebuilt in flood-prone areas.
  • Protecting ecosystems such as wetlands, salt marshes, and dunes that can act as barriers to storms and help shield property.
  • Reforming the National Flood Insurance Program to better communicate actual risk, break the cycle of repeated loss and rebuilding in the most flood-prone areas, and provide incentives to compel communities and homeowners to better prepare for floods.

States Expand Preparation as Floods Increase Nationwide

Quick View

Flood events are becoming more intense across the United States, affecting the physical and economic stability of communities and threatening human lives and delicate ecosystems. Every part of the country is vulnerable to losses from increased flooding; in the past five years, all 50 states have experienced flood events. Federal, state, and local entities share the responsibility for weather-related disaster preparedness and response. This series of fact sheets examines the flood risks, mitigation efforts, and associated costs for states.
