Abstract
Hurricane Katrina devastated a large portion of the City of New Orleans in 2005.
Extensive long-term flooding was caused by failure of the hurricane protection
system. However many residents of New Orleans are victims of repetitive
flooding. This flooding is not due to levee failure and storm surge, but rather
usually from heavy rainfall. This paper focuses on a project by the Center for
Hazards Assessment, Response and Technology (CHART). CHART’s objective
is to support a sustainable Louisiana in light of natural, technological, and
environmental risks. Teams of sociologists, engineers and urban planners assist
in the development of best practices for reducing risks and in implementing these
practices to achieve comprehensive community sustainability.
The specific project of interest focuses on working with small neighborhoods
in the New Orleans area to help reduce the numbers of repetitive flood losses.
This is done through an area analysis, outreach and education. A neighborhood is
selected for an area analysis based on having a high density of repetitively
flooded homes. The team works with the neighborhood association and the city
council person representing the area. Planned drainage improvements are studied
to assess the improvement’s impact on the particular homes in the study area. In
some cases, historic rain gage data is also used in this assessment. Repetitive loss
homeowners answer a questionnaire about their flood experiences. Flood
insurance claims are obtained. A series of neighborhood meetings are held with
the objective of educating each individual owner as to their best flood mitigation
plan.
Keywords: flood mitigation, floodplain management, repetitive flood loss.
