4 What is Risk MAP? In 2009, FEMA developed the Risk Mapping, Assessment, and Planning (Risk MAP) initiative. The goal of Risk MAP is to deliver, in collaboration with State, local, and Tribal entities, quality data that increases public awareness and leads to action that reduces risk to life and property 4

5 Risk MAP Strategies Prioritization Elevation Data Acquisition Watershed Approach Engineering and Mapping Risk Assessment Mitigation Planning Support Risk Communications 5

6 The Paradigm Shift: Map Mod to Risk MAP 6

9 Cumberland County Flood Study - Regulatory 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 feet Datum Conversion from CumberlandCounty Elevation in NGVD 29 Elevation in NAVD NGVD NAVD NGVD NAVD 88 9

10 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 is completed and the suite of synthetic storms has been selected ADCIRC modeling has been validated against historical storms ADCIRC production runs are completed Coordinated with Pennsylvania, FEMA Region III Overland Wave Hazard Analysis: Analysis of wave hazards along coastline Field reconnaissance complete Obstruction carding and transect topography completed WHAFIS modeling completed 10

11 Cumberland County Risk MAP Study Non-Regulatory Scope Cumberland County will receive the following: Flood Risk Products Flood Risk Database Flood Risk Report Flood Risk Map Flood Risk Datasets Flood Depth & Analysis Grids Flood Risk Assessments Areas of Mitigation Interest Flood Risk Database Flood Risk Report Flood Risk Map Flood Risk Datasets 11

15 Areas of Mitigation Interest Purpose and Intended Uses Identify areas that may be affecting flood risk that would benefit from a raised local awareness Raise awareness by local stakeholders of areas within and upstream of the watershed that may be contributing to flood risk and associated interrelationships Provide input to local mitigation plans 15

16 Overview - Areas of Mitigation Interest Items that may have an impact (positive or negative) on the identified flood hazards and/or flood risks Examples include: Riverine and coastal flood control structure At risk essential facilities and emergency routes that could overtopped Stream flow constrictions (e.g. undersized culverts and bridge openings, etc.) Previous assistance and claims Hot Spots (clusters of IA and PA claims, RL, SRL) Significant land use changes Significant riverine or coastal erosion Locations of successful mitigation projects 16

17 Example Area of Mitigation Interest What stopped Sandy: How FEMA's regulations saved Windansea The Asbury Park Press NJ app.com 17

18 Areas of Mitigation Interest Features and Benefits Informs decisions makers on where mitigation actions or additional building code requirements are needed Useful in formulating building code enhancements and prioritizing mitigation actions and identifying needed resources Helps visually communicate flood risk to the public Allows neighboring communities in a watershed study area to see factors that may impact them, fostering collaboration 18

19 Risk MAP Non-Regulatory Products & Datasets - Summary Risk MAP Non-Regulatory Products/Datasets provide a resource to help focus and prioritize the most cost effective mitigation measures Risk MAP Products/Datasets Being Considered: Flood Risk Map, Report, Database Changes Since Last FIRM Flood Depth Grids Flood Risk Assessment (HazUS) Areas of Mitigation Interest 19

20 Local Communities Data Gathering Areas of Mitigation Interest Questionnaire Will be sent to community officials sometime this week This information will help document the flood risk and will be used in Non-Regulatory Products development This information will aid in understanding & preparing to address flood risk for your community We ll provide the draft products during Flood Risk Review meeting The Flood Risk Review meeting will be scheduled approximately one month before the release of Preliminary Maps 20

21 Proposed Schedule Draft Data Sharing & Trainings (Webinar): Early May Flood Risk Review Meeting: July 2013 Deliver Preliminary Map Products: August 30, 2013 Resilience Meeting: September 2013 CCO & Open House Meetings: October/November 2013 Effective: Late

22 Risk Communications Federal/State/Local goals: To create safer communities and reduce risk to lives and property To effectively communicate risk and increase public awareness, leading citizens to make informed decisions regarding their risk Key factors contributing to successful achievement of these goals are: Community engagement and exchange of flood risk information Effective collaboration through partnerships Strategic communications plan development 22

23 Risk MAP Outreach Efforts Meetings Introduction to Risk MAP Risk MAP Project Status Update Draft data sharing training (webinar) Flood Risk Review Resilience CCO/Open House Digital Dissemination The Mapping Information Platform and Map Service Center 23

24 Purpose of Hazard Mitigation To reduce the risk of experiencing damage and disruption as a result of natural hazards Hazard mitigation plans are based on an analysis of risk and propose the implementation of mitigation projects or actions to reduce risk Who has been involved in the development of a hazard mitigation plan? 24

25 Hazard Mitigation Planning Hazard Mitigation Plans: Guides your decisions on mitigation activities for all hazards you face Are an important resource for responding to disasters Facilitates access to federal assistance for mitigation Cumberland County Hazard Mitigation Plan: The County and all the communities adopted 25

26 Cumberland County Hazard Mitigation Plan Status 26

27 Hazard Mitigation Projects Are identified in State and local hazard mitigation plans Provide the best bang for your buck (are cost-effective) Are technically feasible and provide long-term solutions to a problem Have no adverse effects on the environment Are prioritized using the most current risk information (such as Cumberland County Digital Flood Risk Study): Can sometimes be funded by HMA Grants HMGP, PDM, FMA, SRL, RFC 27

28 Mitigation Actions Cumberland County digital FIRMs and non-regulatory products/datasets will provide: Better and accurate data to justify the need for mitigation projects Better data for estimating losses due to flooding Therefore, it will help you identify new mitigation actions or advance existing ones Example Mitigation Actions Land Use Ordinances Zoning, Setbacks, Floodplain Management, etc. Local Building Codes IBC, IRC, Local Regulations, etc. Mitigation Projects Acquisition, Elevation, Floodproofing, etc. Community Identified Mitigation Programs Management Best Practices Integration of natural hazards into other planning mechanisms 28

29 Mitigation Actions (cont.) We looked at your plan and identified the below activities: County wide: Work with NJDEP to more fully understand the dam hazard rankings and methodology behind them, particularly regarding high-hazard sites Provide grants information, planning tools, training, and technical assistance to increase the number of public and private sector hazard mitigation projects Implement mitigation projects and programs intended to reduce risk to critical facilities: County EOC and 911 center flood proofing Bridgeton City: Drainage improvements to the Raceway that protects the city from flooding from the Cohansey River Acquisition/elevation of 1 RP property located on West Lake Street Deerfield, Down, Fairfield Townships: Acquisition/elevation of RL properties Greenwich Township: Use USACE surge maps for community education and outreach 29
