35 Georgia Silver Jackets Flood Risk Management Team 36 BUILDING STRONG

36 About the Georgia SJ Team The Georgia Silver Jackets team brings together individuals from different agencies and fields of expertise to facilitate collaboration, share information, and leverage resources to identify areas in the state that are at risk of flooding and assist communities in reducing risks. The Georgia Silver Jackets team is a one-stop shop for city and county governments to obtain information and assistance to reduce flood risks. 37 BUILDING STRONG

37 What Can Silver Jackets Teams Do? Interagency focus on state priorities Improve overall risk communication (joint messaging) Promote comprehensive flood risk mgmt strategies and policies (shared strategies) Share information (reduce duplication, fill data gaps) Flood forecast inundation mapping Risk MAP support CRS Support Inter-state basin coordination (state-to-state and regional task forces) Storm Surge Modeling State Hazard Mitigation Plan (team assistance in updating) HAZUS data updates High Water Marks NFIP Updates FFRMS Updates BUILDING STRONG

53 City of Roswell Collaboration Alice Champagne, CFM

54 Flood Inundation Mapping (FIM) Program: Communicating Flood Risk and Consequences to Communities Partnership with USGS and City of Roswell and Alpharetta Project Total Cost $ 125,500 $39,450 each city $46,600 USGS Inundation Maps translate flood data into operational maps that communicate risk and the consequences of current and forecasted flooding

55 Flood-Inundation Map of Big Creek in Alpharetta and Roswell Big Creek was selected as inundation mapping site because of the length of record at the Big Creek streamgage ( ) National Weather Service Flood Forecast Point Flooding effects on a large number of people and structures Hydraulic Modeling developed with high resolution lidar elevation data and geospatial imagery Process creates a grid showing depths of flooding feet to 15.0 feet in 0.5 foot intervals. Results show probable areas of floodwater overlaid onto a City map which helps communities plan and respond to floods Published on the web along with an interactive online map viewer

56 Big Creek in Alpharetta and Roswell, GA Flood Levels: 7.5 ft 12.0 ft 15.0 ft

57 Big Creek at Holcomb Bridge Flood Levels: 7.5 ft 12.0 ft 15.0 ft
