6. 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.

16. SPRING CREEK SOUTH
FEMA HAZARD MITIGATION GRANT PROGRAM
(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

17. 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

18. 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

19. 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

22. ALL CONCEPTS: POTENTIAL EDGE TREATMENT

23. SPRING CREEK SOUTH HMGP STATUS
 Concept Design Memo posted on NYSDEC website
 Finalizing schematic concept design
 Draft Environmental Assessment planned public
release end of 2017
 Planned submittal of Detailed Designs
spring/summer 2018 to FEMA for Phase 1 approval

24. 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

25. 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
• 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

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
