This poster displays the estimated equilibrated water depth for central New Orleans. Parts of the city in close proximity to a levee breach may have experienced greater water depths. The data were used to calculate volumes for the unwatering of the City of New Orleans. FEMA'S National Flood Insurance Program used the data to expedite flood insurance claims.
- This poster describes a map that displays the potential loss of functionality (in days) for hospitals within close proximity to landfall of Hurricane Katrina. It also shows the estimated surge inundation from the National Hurricane Center Slosh Model. The purpose of this map is to identify potential damages to hospitals due to wind speeds and to identify potential exposure to storm surge.
- This map shows areas where the 3-second wind gusts from Hurricane Katrina exceeded the American Society of Civil Engineers (ASCE)7 building design levels. These levels are displayed by the census tract and are intended to show the areas likely to suffer damage due to design level exceedance. These are areas where the performance of structures built to design recommendations may be compromised.
HAZUS-MH Building Counts Affected: 100-Year Flood Exceedance and Potential Elevation Requirement, New Orleans, LouisianaThe map displays the 100-year flood exceedance and potential elevation requirements for central New Orleans, LA. The purpose was to quickly identify potential elevation requirements for structures damaged 50% or more as per the NFIP. The 100-year flood exceedance was determined using field surveyed high watermarks and the 100-year BFE taken from current effective FIRMs.
Harrison County, Mississippi: Advisory Base Flood Elevation to Existing Ground Elevation Differential
This map shows the relationship between the ABFE maps and the relevant pre-event existing ground elevation data. The existing ground elevation was taken from the pre-event topographic aerial data.
- The map illustration shows the relationship between a building in Pass Christian, MS that survived Hurricane Katrina and mapped flood hazard boundaries, observed impacts of the storm and relevant elevation data. The graphic utilizes post-event aerial and ground photography, GIS-based flood hazard data, and the FIRMs in effect at the time of the storm.
- FEMA's DFIRMs reflect the engineering back-up material used to develop the map. DFIRMs are produced using GIS technology which allows users to create customized maps.
- In the wake of Hurricane Katrina, FEMA initiated a project to produce high-resolution maps that show flood impacts from the storm for portions of Harrison, Hancock, and Jackson Counties in Mississippi. The purpose of these maps were to provide local government and citizens with the best and most up to date information about coastal flood hazards to aide in the rebuilding process. These maps are referred to as "Katrina Recovery Maps."
- Using FEMA's Katrina and Rita Flood Recovery Maps, the Gulf Coast is being rebuilt safer and more disaster resistant than ever before.
- In response to the severe coastal flooding caused by Hurricanes Katrina and Rita FEMA undertook a fast-track project to develop advisory flood maps for use by affected communities and citizens during the rebuilding process. Until FEMA can complete new, detailed Flood Insurance Studies (FISs) and Flood Insurance Rate Maps (FIRMs) for the Louisiana coastal parishes that border the Gulf of Mexico or Lake Pontchartrain, these advisory maps fill a critical interim need for up-to-date coastal flood risk information.
- The maps show the magnitude of Hurricane Katrina's winds with respect to the design winds for the area affected by the storm. The maps helped FEMA communicate that for the majority of the area affected by Katrina, buildings designed to the correct national standards should have stood up to well to the winds.
Hazus-MH was used in the preparation of a study of building damage and losses likely to occur due to a repeat of the 1906 San Francisco earthquake. The map shows estimates of Displaced Households from a repeat of the 1906 event. Hazus-MH also estimates short-term shelter requirements. These products are very useful in assessing potential short-term shelter and long-term housing requirements following a major earthquake.
Depicted in this map are direct economic losses from a possible recurrence of the 1906 event. These losses include capital stock losses and income losses. These estimates are useful in quickly estimating the distribution of economic losses from earthquakes.
Hurricane Katrina: GIS Spatial Analysis of Flood Impacts in Mississippi- Damaged Primary Residences Outside the High Risk Flood Areas
Roughly 25 percent of flood insurance claims are for structures that are in low- to moderate-risk areas. The map shows the damaged primary residences, outside the high risk flood area, having homeowners insurance but not flood insurance and the depth of flooding suffered.
Hurricane Katrina: GIS Spatial Analysis of Flood Impacts in Mississippi - Residential Substantially Damaged Buildings in Relation to the Advisory Base Flood Elevations and Q3The map depicts Q3 data for substantially damaged residential structures located within the 100- and 500-year floodplain. Of the 2,342 structures damaged by the hurricane, 91% received damages that cost over 50% of the fair market value before Katrina. More than 50% of the damaged buildings were greater than 90% damaged.
Hurricane Katrina: GIS Spatial Analysis of Flood Impacts in Mississippi- Post Hurricane Katrina Advisory Base Flood Elevation and Q3 ComparisonImmediately after Katrina, FEMA conducted assessments of coastal flood elevations, called ABFEs in Mississippi and Louisiana to provide State and Local officials with more accurate data and to guide local decisions regarding reconstruction. Since flood damage is not covered under homeowners insurance, residents of structures without flood insurance could only recoup damages caused by non-flood sources.
- Displays maps used for risk identification, risk reduction, risk communication, risk assessment and risk insurance.
- Dispays the maps used for risk identification, risk reduction, risk communication, risk assessment, and risk insurance.
- This poster describes the steps that the city of St. George, Utah took to reduce flooding losses and shows the positive effects that resulted.
- Since the 1970s, FEMA has provided flood hazard maps to help manage and reduce risk for the more than 20,000 communities that participate in the NFIP. All paper flood maps are now also available as Flood Insurance Rate Map (FIRM) scan images. Additional digital flood map products, shown in this poster, have helped streamline processes while reducing the demand for paper maps.
