    Jim Schwab, FAICP Hazards Planning Center Manager American Planning Association


  • Nate Woiwode Project Manager, North American Risk Reduction and Resilience Priority The Nature Conservancy

    Katherine Hagemann Resilience Program Manager Office of Resilience, Miami-Dade County

    Karen Sands, AICP Director of Planning, Research and Sustainability Milwaukee Metropolitan Sewerage District

    Speakers Jacob Pederson Program Coordinator Floodplains for the Future, Pierce County

    Jill Dixon Senior Urban Planner Sasaki Associates


    PIE is the result of an agreement between APA and FEMA, with ASFPM as partner, to produce a series of educational webinars on best practices in hazard mitigation planning.

    Webinars revolve around 4 central themes: • Focus on all hazards. • Focus primarily on mitigation planning but

    also its connections with recovery planning and preparedness.

    • APA and ASFPM act as co-conveners of all planning exchange webinars.

    • Planning exchange hosts will select topics and commit to moderate, present, and lead the planning exchange webinars.

  • Today’s Presentation

  • “mangrove forests with widths of 6-30 km along the Gulf Coast of South

    Florida attenuated storm surges from Hurricane

    Wilma (Category 3) by reducing both the

    amplitude and extent of overland flooding,

    protecting the area behind the mangroves

    from inundation. Numerical simulations

    show that the inundation area by Wilma would

    extend more than 70% further inland without the

    mangrove zone” -Zhang et al 2012
