8. 8 Risk MAP Review

9. 9  Mapping partner to complete Salem 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 Salem County Flood Study - Overview

10. 10 Salem County Flood Study - Scope  Incorporation of approximately 23 miles of detailed riverine redelineation and 170 miles of approximate riverine  Restudy of all coastal hazard zones - 20 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 – 1.04 feet 894’ NAVD 88 895.04’ NGVD 29 Elevation in NGVD 29 Elevation in NAVD 88 896’ NAVD 88 897.04’ NGVD 29 Datum Conversion for Salem County

11. 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

14. 14  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 Salem County Flood Study - Current Status

15. 15  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 Received response only from Mannington Township 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 Local Communities
