Risk MAP Early
Demonstration Projects in
Region II
2011 Association of State Floodplain Managers
May 17, 2011
Louisville, KY
Overview
FEMA Region II was asked to develop potential
demonstration projects to better field test proposed Risk
MAP datasets and products
Three projects were identified in New York:
 Broome County Depth Grid and HAZUS-MH Development/Area of
Mitigation Interest
 Great Lakes Discovery Process Development
 Mohawk River Depth and Velocity Grid Development and Comparison
One project was identified in New Jersey:
Passaic River Basin Areas of Mitigation Interest

Mitigation Planning is Key
Hazard Mitigation Planning is part of the overall planning for
any community – Comprehensive, economic development,
infrastructure, mitigation and emergency planning are all
facets of the same process.

Broome County, NY
Why A Project in Broome County?
 New Hydrology indicated an upward trend in flood
discharge
 Increased flow created potential issues due to levee
deaccreditation
 New Risk Mapping Assessment and Planning (Risk MAP)
products provide communities additional tools for
planning
 Broome County had the basic requirements, a strong
Geographic Information System (GIS) and data

Broome County HAZUS-MH Study
7
Field Data Acquisition -Enhanced
Enhanced HAZUS Level 2
 First floor elevation
 Building Type – residential,
commercial, critical facilities
 Basement or not

Depth Grid Analysis

Example Area of Mitigation Interest
 Robinson St. was initially
identified as the sole source for
flooding of a large area
 The area was of interest to the
City of Binghamton as a potential
economic development site

Example: Area of Mitigation Interest
12
Example: Area of Mitigation Interest
 Flood Control Structures at the Underpasses
 Property Protection Measures
 Site Specific Structural Protection
 Flood Insurance
 Combinations of above methods
 No Action
13
Mohawk River
Study area including: Village of Fonda and Village of Fort
Plain located within Montgomery County, New York.
State, local, and tribal officials can use the summary
information provided in a Flood Risk Report, in conjunction
with the data in the Flood Risk Database, to:
 Update
Local hazard mitigation plans
Community comprehensive plans
Emergency operations and response plans
 Develop hazard mitigation projects
 Communicate flood risk
 Guide modifications of development standards

Early Demonstration Project
(New Jersey)
Project Scope
Early Demonstration Project Combines a detailed Analysis of one
Area of Mitigation Interest (AoMI)
with
Mitigation Planning Technical Assistance
20
Mitigation Planning Technical Assistance
Purpose
Ensure all Risk MAP projects receive sufficient
technical assistance to enable the community, and
thus FEMA, to meet the goals of Risk MAP
21
Scope Overview
 Present current information and recommendations for mitigating high-
risk floodprone structures
 Includes Repetitive Loss and Severe Repetitive Loss Properties in:
 Fairfield
 Little Falls
 Lincoln Park
 Pequannock
 Pompton Lake
 Uses National Flood Mitigation Data Collection Tool (National Tool)
• Collects property-specific data for floodprone properties
• Validates and stores detailed risk information for structures
 Develop appropriate mitigation recommendations at both the community
mitigation planning level as well as at the structural or project specific
level
22
Task 1 – Preliminary Data Collection,
Prioritization, and Kick Off Meeting
 Data Collection
 Claims history and policy information
 Property characteristics
 Value
 Standardized address
 Flood Insurance Rate Map Information
 Mitigation actions taken
 Topographic data
 Geo-coded property locations (X and Y coordinates)
 Prioritization based budget
 All SRL, RL with $50k or more, clustering
 Total of 650 structures
23
Task 2 – Site Visits for Validation, Collection
of Field Data and Photographs
 4 Inspectors for approximately 11 days
 650-700 properties
 Collecting
 GPS Coordinates
 Foundation type
 Condition
 Photographs
 Mitigation observed
 Other
24
Task 2 – Site Visits for Validation, Collection
of Field Data and Photographs (cont.)
 Post Field Data Collection Township Data Collection
 Elevation certificates for elevated structures
 Building demo permits for mitigated structures
 Other information needed to fill gaps
25
Task 3 – Develop Specific Recommendations
for Mitigation
 Evaluate standard mitigation options for each property validated in the
National Tool using FEMA 551
 Generate worksheets and rank mitigation measures for each property
 Considers drainage improvements, barriers, wet and dry-floodproofing,
elevation, relocation, and acquisition
 Considers relative cost, human intervention, and annual maintenance
 Consider project type as it relates typically to NEPA compliance
 Deliverable – community specific report listing properties by community
with maps – explanation of how options were evaluated –
recommendations for cost-effective mitigation
26
Task 4 – Develop community-level recommendations
for mitigation plan updates or improvements
 Obtain and review most recent plans
 Consult NJ State Hazard Mitigation Plan
 Develop community level planning recommendations
addressing how the communities could use the project
information to improve their plans and to obtain HMA grant
assistance
27
Areas of Mitigation Interest
Mitigation Planning Linkages
There are several required areas for mitigation
plans for which Areas or Mitigation Interest
might be helpful:
Risk Assessment Product
Mitigation Planning Requirement
Areas of Interest
44 CFR Part 201(d)(3), revise plans to reflect changes
44 CFR Part 201.6(c)(2)(i), profiling hazards
44 CFR Part 201.6(c)(2), risk assessment
44 CFR Part 201.6(c)(3), developing mitigation strategies
28
Desired Outcome
Communities will use the instructional report to
conduct similar research for remaining properties
Communities will use the data to:
 Update their mitigation plans
 Hazard Profiles
 Quantitative Risk Assessment
 Mitigation Strategy Development
Prioritize projects
Develop project applications
Take action to reduce losses!!!
29
EDP Lessons Learned
 It sounds repetitive but close, direct , and constant communication with
communities and stakeholders is paramount for the success of Risk
MAP projects.
• It helps in stakeholder understanding Risk MAP vision.
 The products were overall, very well received by communities
• It creates trust and a sense of partnership
 The stakeholders can better understand and accept the limitations of the program
as much as the benefits.
 The communities are planning on using the data in a variety of ways
• It opens the vaults of knowledge and information from communities to
contractors
 The stakeholder's knowledge of the local areas and specialized datasets were
CRITICAL for producing the products.
