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

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

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
Cumberland County Flood Study -Overview
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

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 createdfrom 1:24,000 USGS quads

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
Cumberland County Flood Study -Current Status
