Drainage Improvement Project Development for Successful Hazard Mitigation Funding

Author(s): Talbot, M. ;  Quarles, J.;  Bass, D.;  Jourdan, N.;  Swagart, G.

Over 100 drainage improvement project proposals were considered for Katrina Hazard Mitigation Grant Program (HMGP) funding in 2008 and 2009, by the Mississippi Emergency Management Agency, with assistance from FEMA. Many of these project proposals displayed technical merit and detailed the scope of work and estimated project costs. Completion of these projects could have reduced future flood levels and associated future flood damages in many communities. However, most of these proposals had insufficient damage history data needed to determine the benefits of the mitigation projects. Benefits are defined as avoided damages, disruptions, losses, etc., as a result of the mitigation. For HMGP funding approval, the FEMA Benefit Cost Analysis (BCA) musts show that the benefits of a project are equal to or exceed the project cost. The FEMA Damage-Frequency Assessment (DFA) BCA module is used for localized drainage improvement projects when Flood Insurance Study (FIS) or comparable data are not available. This paper presents an overview of the DFA module and the necessary documentation requirements. Further, suggestions for developing routine collection of the needed documentation to apply the DFA module for drainage improvement projects are outlined. This information will assist communities to be better prepared to successfully apply for HMGP funds that might be available in the event of future disaster declarations.

Responsible Site Design: Implementing Innovative Stormwater Management Strategies

The primary goal of the workshop is to create a dynamic learning experience that examines the role of stormwater management in the built environment. The workshop will focus on integrating ecologically sound water management approaches into site design. After the workshop, attendees will be familiar with the following concepts and technical issues:

  • Knowledge of the stormwater treatment chain
  • Knowledge of the impact of land use codes on stormwater management
  • Application of a design process that mitigates the effects of stormwater on-site
  • Knowledge of the relationship between land use codes and design for innovative stormwater management
