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.
