Role of CSC
CustomerFocused
TechnologyExperts
Where
we’re
require
d to be
Acting as the “Middle-man”
• Must know the customer as well as the technology (have to straddle the fence)
• Effectively “buying down the cost” for coastal information and tools

Customers: State and Local Coastal Resource Managers
• Emergency managers• Floodplain managers• Protected areas• Coastal planners• Regulatory agencies• Fish and wildlife agencies• Estuarine reserves• Sea Grant programs• Educators
NOAA Coastal Services Centerhttp://www.csc.noaa.gov
Coastal Hazards Theme: Provide emergency/floodplain managers with GIS-based coastal hazard tools and spatial data that will assist them in mitigating against, responding to, and recovering from the impacts of coastal hazards

water depth, & flood categories
• 16 locations in North Carolina now on website
• 35 locations for Gulf of Mexico region will be on website in the next year
• Partnering with FEMA Map Modernization program to decide which region to look at next

Comprehensive Hurricane Preparedness Study
• CHPS expands on Hurricane Evacuation Study.
• Chatham County, GA Pilot• Remap Storm Surge Zones – GIS
model• Map Shallow Coastal Flooding• Data Access for multiple county
agencies
• Center will work with other states/counties to acquire, set up, and run the model.
![Page 17: Gulf Coast Hurricane Preparedness Conference NOAA TOOLS FOR HURRICANE EVACUATION Todd Davison, NOAA Gulf Coast Services Center November 12, 2008 Mobile,](https://reader035.vdocuments.us/reader035/viewer/2022062312/55155720550346a1418b4717/html5/thumbnails/17.jpg)
• GIS model uses a DEM and SLOSH model MOMs to determine surge extent for each Saffir-Simpson hurricane category (1 to 5)
• Model output is a shapefile representing the horizontal extent of surge for a category
• Remapped surge zones• redefine evacuation zones
• recalculate clearance times
• more efficient evacuations and planning

Digital Elevation Model
• Mapping inundation starts with base DEM• Quality of output highly
dependent on quality of DEM
• Created from bare earth lidar• Integrated bathymetry from
model mesh to create a seamless topobathy surface
• Downloaded from LDART• Flew lidar for Walton,
Escambia, and Santa Rosa Counties
