  2. Agenda • Introductions and Roll Call • Objectives • Risk Mapping, Assessment, and Planning (Risk MAP) Program Overview • Current status of Cumberland County flood study • Milestones • Questions

  3. Introductions and Roll Call • FEMA Region II Project Manager: Paul K. Weberg, PE Communications / Outreach Support: William McDonnell Floodplain Management and Insurance Lead: Pat Griggs & Kim Rizzo Regional Support Center (RSC) Deputy Coordinator: TolgaYilmaz, CFM, GISP RSC Outreach Lead: Crystal Smith, CFM • State – New Jersey Department of Environmental Protection (NJDEP) Supervising Engineer: Joseph Ruggeri, PE, CFM Supervising Engineer: John Scordato Technical Assistance: A. Chris Gould, CFM • Mapping Partner - RAMPP Project Manager: Milver Valenzuela, PMP, CFM, GISP • Local - Cumberland County & Communities

  4. Objectives • Objectives • To provide an overview of current status of Cumberland County’s mapping project status • To promote community engagement and enhance capability to effectively manage flood risk • Questions & Feedback from the communities

  5. Risk MAP Program Overview • Risk Mapping, Assessment, and Planning (Risk MAP) is a new FEMA program that provides communities with flood information and tools they can use to enhance their mitigation plans and better protect their citizens • The Risk MAP program aims to achieve these goals through new and updated strategies and products that address: • Elevation data acquisition • Watershed study approach • Engineering and mapping • Risk assessment, mitigation planning support • Risk communications

  6. Risk MAP

  7. NJ Mitigation Plan Update

  8. Risk MAP Review

  9. Cumberland County Flood Study -Overview • Mapping partner to complete Cumberland coastal and riverine analysis by mid-2012. • Preliminary FIS Report & Digital Flood Insurance Rate Map (DFIRM) panel and database production will be funded in the near future • Project Team • Risk Assessment, Mapping, and Planning Partners (RAMPP), a joint venture of Dewberry, URS, and ESP • Tasks • New Approximate Hydrology & Hydraulics (H&H) • Redelineation of Detailed Riverines • Restudy of all coastal hazard zones

  10. Cumberland County Flood Study - Scope • Incorporation of approximately 150 miles of detailed riverine redelineation and 125 miles of approximate riverine • Restudy of all coastal hazard zones - 44 shoreline miles of detailed coastal analysis • All the coastal and riverine analysis will be produced in the FEMA Countywide format in the North American Vertical Datum of 1988 (NAVD88) • NAVD 88 = NGVD 29 – 1.11 feet Datum Conversion from CumberlandCounty Elevation in NGVD 29 Elevation in NAVD 88 897.11’ NGVD 29 896’ NAVD 88 895.11’ NGVD 29 894’ NAVD 88

  11. Coastal Storm Surge and Overland Wave Hazard Analysis • Storm Surge: Analysis of tropical and extratropical (northeasters) using ADCIRC model and JPM statistical model • Topography and bathymetry complete • ADCIRC mesh is completed • Statistical analysis of storms nearing completion • ADCIRC modeling is currently being validated against historical storms • Coordinated with Pennsylvania, FEMA Region III • Overland Wave Hazard Analysis: Analysis of wave hazards along coastline • Field reconnaissance complete • Obstruction features are near completion using GIS

  12. Cumberland County Flood Study - Affected Panels • Some of the communities may be covered • with more than one panel • Paneling scheme created • from 1:24,000 USGS quads City of Vineland

  13. Cumberland County – NFIP Policies, Claims, Repetitive Losses, CRS, CAC & CAV

  14. Cumberland County Flood Study -Current Status • Countywide LiDAR-based terrain has been built from LAS files provided by USGS (data collected in April, 2008). This represents a seamless high accuracy elevation model that supports all modeling and mapping activities. • Coastal analyses are currently ongoing. Transect (Coastal Cross Sections) layouts have been defined. Obstructions have been modeled. Field reconnaissance has been completed. • Approximate Hydrology and Hydraulics are in advanced stages. • Redelineation of riverine miles is in advanced stages. Mapping will be finalized when all other analyses are complete. • Awaiting response from communities to the letters sent out in January, 2010 regarding data request

  15. Local Communities • Contacted each community letting them know about coastal field reconnaissance and field survey taking place in their communities in August 18, 2010, and data request in January 6, 2010 • Have not received any responses • Responses are required for your input to be considered • Roles & Responsibilities of Local Communities: • Response to the letters sent out in January, 2010 • Flood Risk communications with residents

  16. Milestones • Next Coordination Call: August, 2011 • Coastal Surge completed by: October, 2011 • Coastal Overland completed by: January, 2012 • Coastal and Riverine Analysis complete by : Mid 2012

  17. Recent Activities • Similar meetings conducted: • Morris: April, 2010 • Bergen: June, 2010 • Somerset: June, 2010 • Essex: July, 2010 • Monmouth: August, 2010 • Union: August, 2010 • Cape May: September, 2010 • Passaic: October, 2010 • Middlesex: October, 2010 • Atlantic: November, 2010 • Ocean: December, 2010 • Future coordination calls with: • Salem • Other project target dates for preliminary maps: • Morris and Bergen: June-September 2011 • Rest of the Counties: Early – Mid 2012
