JAMAICA BAY PLANNING REGION
Baseline Conditions and Water
Resource Problems
• Loss of 75% of marsh habitat
(over 2000 acres in the last
century)
• Disappearance of Marsh Islands
• Shoreline dominated by non-
native, invasive plant species,
which is a threat to existing
desirable wetland habitats
• Poor benthic habitat
• Poor tidal flushing and circulation
• Continuing shoreline erosion
• Fill and hardened shorelines
• Poor water quality, landfill
leachate, Confined Sewer
Overflows (CSOs) and waste
water discharges
• Straightened and deepened creek
with no finger tributaries (Fresh
Creek)
• Trash and debris
Restoration Opportunities/Measures
• Habitat improvements
• Wetland restoration/creation
• Invasive species removal/native
species plantings
• Tidal Channel
modification/realignment
• Bank stabilization
• Tidal Channel geomorphology
restoration
• Sediment load reduction
• Basin bathymetry reconfiguration to
promote optimal circulation
• Beneficial re-use of material onsite
• Public education/access
Jamaica Bay, Marine Park and Plumb Beach "Source" Feasibility Study Background
• Study Resolution (1990), Reconnaissance Report (1994) and Feasibility Cost Share Agreement
executed with NYCDEP (1996).
• 39 restoration opportunities identified and evaluated.
• Eight (8) restoration sites recommended at USACE milestone meeting in 2010.
• Hurricane Sandy 113-2 Interim Report #2 to Congress identified study to be evaluated for Coastal
Storm Risk Management.
• Restoration opportunities considered in the "perimeter plan" for East Rockaway to Rockaway -
Jamaica Bay Reformulation Study. However, Storm Surge Barrier selected as Tentatively Selected
Plan.
• Six (6) of eight (8) sites were evaluated further for recommendation in HRE Feasibility Report.

(HMGP) PROJECT
Goals
Manage coastal storm risk with Natural/nature-
based features
Design for self-sustaining and long-term
resilience
Use integrated approach throughout site
Decrease risk of fire
Align with NPS GNRA Management Plan
Coordinate with complementary Jamaica Bay
projects
PROJECT PARTNERS
• FEMA – grantor
• NYS DHSES – grantee
• NYS DEC – subgrantee
• NPS – landowner
• USACE – project manager contracted by DEC
• A/E Team – Princeton Hydro, Parsons Brinckerhoff,
HDR
• NYC DOT & NYC DPR – adjacent
landowner/manager
PHASE 1 PRELIMINARY CONCEPT PLANS
Concepts (Starting Point):
• vary combination of Nature-Based Features and
measures that manage coastal storm risks, provide
ecosystem benefits and enhance resiliency
• vary in level of excavation activities and movement of
soil
• will be refined and further evaluated to demonstrate
level of protection, costs, benefits, sustainability and
maintenance
• complement other projects/actions
PHASE 1 PRELIMINARY CONCEPT PLANS
COMMON FEATURES
Berm
o 17-19 foot (NAVD 88) berm
o 50-foot-wide path at crest
o tie-ins at Belt Parkway and Addabbo Bridge
Freshwater wetlands
Flap gates
Nuisance stormwater control
Local access points
Improved edge aesthetic

HIGH FREQUENCY FLOODING RISK
REDUCTION FEATURES (HFFRRF) FOR
ATLANTIC COAST OF NEW YORK EAST
ROCKAWAY INLET TO ROCKAWAY INLET
AND JAMAICA BAY
24
• Manage flood risk resulting from high frequency flooding
in the back-bay
• Build off the previous work done for Rockaway Study and
for NYC on the Raised Shorelines project
• Further screen, identify, and develop these measures for
inclusion in the Final GRR/EIS
• Projects must be independently justified with a positive
BCR and must be able to function independently in
advance of the construction of a storm surge barrier
OBJECTIVES OF HFFRRF
• Manage flood risk resulting from high frequency flooding
in the back-bay
• Build off the previous work done for Rockaway Study and
for NYC on the Raised Shorelines project
• Further screen, identify, and develop these measures for
inclusion in the Final GRR/EIS

o Conceptual design of features
o Functional and Structural design
basis
o NO pumps or alterations to the
existing drainage system
Prototype Risk Reduction Features
to include
o Small floodwalls
o Berms
o Bulkhead raising
o Road closure/flood gates
o Natural and nature based
