3 Introductions and Roll Call  FEMA Region II Project Manager: Paul K. Weberg, PE Communications / Outreach Support: Adie Koby Senior Engineer: Alan Springett Floodplain Management and Insurance Lead: Pat Griggs RSC Deputy Coordinator: Tolga Yilmaz, CFM, GISP  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 - T.Y.Lin / Medina Project Manager: John Chayko, PE, CFM  Local - Burlington County & Communities

4 Objectives  Objectives To provide an overview of Burlington County’s flood hazard mapping project status To introduce new Risk MAP program To promote community engagement and enhance capability to effectively manage flood risk

5 Map Modernization (MapMod) Program Overview  Prior to 2003, more than 70 percent of the nation’s flood maps were at least 10 years old. In Burlington County, with few exceptions, the communities' flood maps dated back to the 1980s  Congress appropriated funds in 2003 and directed FEMA to develop and implement the MapMod program, which: Created county-wide digital maps Utilized more current data to update maps Developed a new platform to convert from paper to digital format

6 Burlington County MapMod Update  Original scope of Burlington County study County-wide DFIRM (188 panels), including 40 incorporated communities New detailed studies for 48.2 stream miles Re-delineation/re-use of miles of detailed studies  Re-delineation: Previously identified floodplains and associated detailed flood elevations paired with updated topographic data that retains the integrity of the existing Engineering analysis Digital lift-up of 847 approximate stream miles  Digital lift-up: Using the floodplain boundary from the old effective maps as-is, without using the updated aerial or the updated topographic data Incorporation of NJFHA boundary to the DFIRM maps and Flood Insurance Report (FIS) profiles The DFIRM and FIS report will be produced in the FEMA Countywide format in the North American Vertical Datum of 1988 (NAVD88)  NAVD 88 = NGVD 29 – 1.2 Preliminary DFIRM delivery scheduled for November 30, 2010  Adjusted scope of Burlington County study Post-preliminary process will be postponed until new LIDAR is collected

7 Burlington County-wide Paneling Scheme

8 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
