Post-Flood Debris Management
Debris Estimation Post-Flood • Structures in the floodplain tell PART of the story • Understand that there will be debris generated in that area • Must verify data, do not rely on maps alone 8
Mobilizing Resources • Debris takes time to accumulate after a flood • Pushback from contracted resources who anticipated a hurricane • Difficult to manage • Straight to landfill vs. DMS 9
Volunteers in Disasters Coordinating with VOADs in Debris Management 10
Social Media and Public Information 2008 vs. Today 11
Staff Turnover 2008 vs. Today • Debris plan backups • Lots of turnover since 2008 • Multiple contacts for debris contractors • Contingencies and redundancies in plans Don’t rely on one just one person ! 12
FEMA PA, IA and Hazard Mitigation Programs
Hazard Mitigation Assistance • FEMA Hazard Mitigation Assistance (HMA) Programs − Hazard Mitigation Grant Program (HMGP) − Pre-Disaster Mitigation Grant (PDM) − Flood Mitigation Assistance (FMA) 14
Changes to Pre-Disaster Mitigation Grant Program • Assist communities with Pre-disaster mitigation activities • FEMA revised application limits • Increased caps for projects and planning • Prioritization for projects and applicants 15
Future Opportunities
Gathering Data for the Disasters • Substantial Damage Data • Red Cross CAN • FEMA Individual Assistance • United Way 211 • Other Volunteer Organizations 17
HUD CDBG-DR Allocations • 2015 Supplemental Allocation - $300M • 160M – South Carolina • 140M – Texas • $24M – San Marcos • $66M – City of Houston • $50M – State of Texas • 80% must be spent in • Harris County • Hidalgo County • Hays County • Travis County 18
Resiliency Programs Community Development Block Grant • One of the longest ‐ running Department of Housing and Urban Development (HUD) programs • Funds local community development activities such as affordable housing, anti ‐ poverty programs, and infrastructure development • Covers some programs that can mitigate debris risks 19

Opportunity for Mitigation/Resilience Planning • Case Study – NY Rising Community Recovery Program 23
Project Overview • The NY Rising Community Reconstruction (NYRCR) Program, announced by Governor Andrew M. Cuomo in April of 2013, is a more than $650 million planning and implementation process established to provide rebuilding and resiliency assistance to communities severely damaged by Hurricane Irene, Tropical Storm Lee, Superstorm Sandy, and the summer floods of 2013. Drawing on lessons learned from past recovery efforts, the NYRCR Program is a unique combination of bottom-up community participation and State-provided technical expertise. This powerful combination recognizes not only that community members are best positioned to assess the needs and opportunities of the places where they live and work, but also that decisions are best made when they are grounded in rigorous analysis and informed by the latest innovative solutions .
Program Goal • The goal of the NYRCR Program is to empower the State’s most impacted communities with the technical expertise needed to develop thorough and implementable reconstruction plans to build physically, socially, and economically resilient and sustainable communities so as to rebuild New York’s communities in a way that will mitigate against future risks and build increased resilience.
Mad Brook Retaining Wall I mprovements Anecdotal evidence suggests the existing retaining wall has provided flood protection up to the 100 ‐ year event but has begun to fall into disrepair. This project proposes to rehabilitate the existing retaining wall to ensure future protection.
Mad Brook Watershed Study The Effective FEMA model does not include the retaining wall and does not adequately capture the dimensions and profile of the stream This project would prepare a refined model of the watershed and stream to better define instream and bridge replacement projects.
Public outreach HEC-RAS Model • Developed by U.S. Army Corps of Engineers • Simulate the water flow through a drainage area • Predict the Water Surface Elevation (WSE) and extents of flooding for a given storm event • E.g., 100-year or 1% annual-chance event • Assess the effectiveness of flood mitigation alternatives • Evaluate and compare potential benefits in terms of reduced flooding WSE and extents 28
Strategy 3: Reduce risks for residents and visitors by addressing stream conditions causing or contributing to repetitive flood damage, increasing protection for property from future flood damage and promoting safe and adequate housing for all residents. Residential and Windham Windham Windham Flood mitigation improvements for Commercial residential and commercial properties to Resiliency enhance structural resilience, preserve Improvements the tax base and improve safety for occupants. Possible improvements to include elevation/flood proofing, and voluntary acquisitions/buyouts Protective Measures Business relocation Windham Windham Windham Creation of targeted business relocation and expansion and expansion areas – Identify areas areas outside of the flood plain for potential relocation of at-risk businesses and conduct site improvements, infrastructure Protective extensions and permitting/approvals Measures Senior/Affordable Windham Windham Windham Creation of senior-oriented and/or Social/Comm Housing Creation affordable housing unity Services Stream Projects Windham Windham Windham Improve stream conditions to enhance Hamlet behind property protection, water quality, and WAJ Central stream functionality. Possible strategies School, include (1) bank Center restoration/stabilization/channel Church etc. or restoration of Mad Brook and Batavia Kill, Hensonville - (2) invasive species removal, and (3) behind homes debris removal near Rt. 65 Protective bridge Measures
