Public Participation in Natural Hazard Mitigation Policy Formation: Challenges for Comprehensive Planning

Journal of Environmental Planning and Management (2003)

David R. Godschalk Samuel D. Brody Raymond J. Burby

Democratic theory holds that active participation in governmental planning and decision making is critical to furthering the public interest. As a result, public participation in urban planning in the US is arguably the most extensive and intensive in the world. Required by federal, state and local laws, citizen involvement is a staple of local plan making. However, as this paper shows, citizen interest in participating in the formulation of hazard mitigation policies in comprehensive plans is low, despite mounting evidence of perils to life and property from floods, hurricanes and earthquakes. Using evidence from case studies in Florida and Washington, the causes of disinterest are dissected and ways to increase public input to hazard mitigation policies in local comprehensive plans are recommended.

Evaluation of flood risk reduction strategies through combinations of interventions

Journal of Flood Risk Management (2018)

Erik C. van Berchum William H. Mobley Sebastiaan N. Jonkman Jos Timmermans Jan H. Kwakkel

Large, complex coastal regions often require a combination of interventions to lower the risk of flooding to an acceptable level. In practice, a limited number of strategies are considered and interdependencies between interventions are often simplified. This paper presents the Multiple Lines of Defence Optimization System (MODOS)‐model. This quick, probabilistic model simulates and evaluates the impact of many flood risk reduction strategies while accounting for interdependencies amongst measures. The simulation includes hydraulic calculations, damage calculations, and the effects of measures for various return periods. The application and potential of this model is shown with a conceptual and simplified case study, based on the Houston‐Galveston Bay area. The analyses demonstrate how the MODOS‐model identifies trade‐offs within the system and shows how flood risk, cost, and impact respond to flood management decisions. This improved understanding of the impact of design and planning choices can benefit the discussions in finding the optimal flood risk reduction strategy for coastal regions.

Quantification of continuous flood hazard using random forest classification and flood insurance claims at large spatial scales: a pilot study in southeast Texas

Natural hazards and earth system sciences (2021)

William H. Mobley Antonia Sebastian Russell Blessing Wesley E. Highfield Laura Stearns

Abstract. Pre-disaster planning and mitigation necessitate detailed spatial information about flood hazards and their associated risks. In the US, the Federal Emergency Management Agency (FEMA) Special Flood Hazard Area (SFHA) provides important information about areas subject to flooding during the 1 % riverine or coastal event. The binary nature of flood hazard maps obscures the distribution of property risk inside of the SFHA and the residual risk outside of the SFHA, which can undermine mitigation efforts. Machine learning techniques provide an alternative approach to estimating flood hazards across large spatial scales at low computational expense. This study presents a pilot study for the Texas Gulf Coast region using random forest classification to predict flood probability across a 30 523 km2 area. Using a record of National Flood Insurance Program (NFIP) claims dating back to 1976 and high-resolution geospatial data, we generate a continuous flood hazard map for 12 US Geological Survey (USGS) eight-digit hydrologic unit code (HUC) watersheds. Results indicate that the random forest model predicts flooding with a high sensitivity (area under the curve, AUC: 0.895), especially compared to the existing FEMA regulatory floodplain. Our model identifies 649 000 structures with at least a 1 % annual chance of flooding, roughly 3 times more than are currently identified by FEMA as flood-prone.
