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

Storm Mapping Tutorial

• aid emergency and coastal managers during hurricanes….

• by showing how to find and use NOAA meteorological and hydrological data….

• and stepping through GIS procedures to generate map products that address storm-related hazards.

HURREVAC Quick Reference GuideHURREVAC Quick Reference Guide• Collaboration with FEMA

Region IV

• Provides quick reference to Government Officials on HURREVAC functionality

• Highlights GIS functionality and using NOAA forecast data

• Available on Hurricane Preparedness Website

http://www.nhc.noaa.gov/HAW2/pdf/hurrevac_guide.pdf

HURREVAC Storm Surge Module

• Available through tide gages

•Features- Exercise mode

- SLOSH forecast mode

- 20% error margin

- Gage marked with S when real time data available

Flood Severity Mapping

• Visualize NWS flood categories• Display potential flood inundation for each of

the NWS categories• Flood Stage and below• Minor Flooding• Moderate Flooding• Major Flooding, including Flood of Record

• Graphical depiction of flood risk and impacted areas

Flood Severity Mapping• Show inundation extent,

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.

• 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

Mapping Storm Surge Zones

Project Objectives:

• Assess needs of management community

• Assemble needed data

• Test a prototype storm surge model (hindcast Ivan)

• Improve inundation mapping

• Develop mapping and educational products

Pilot Project AreaHurricane Ivan Impact Area

ADCIRC model

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

Hurricane Evacuation Zones Tool

• Purpose Provide a template for emergency managers to easily supply the public with evacuation zone information

• TemplateDemonstrated on the Center website as an example application for a fictitious community

• AccessTemplate (code) and set-up documentation available upon request to federal, state, and local officials

• Sample addresses

• Default code is parcel search (option for geo-coded streets)

Application: Address Search Page

• Simple mapping interface

• Evacuation zone display is specific to searched address

• Option to view all evacuation zone definitions

Application: Map Display
