  5. 5. 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.

  11. 11. SPRING CREEK NORTH PLANTING PLAN
  12. 12. PROGRAM COORDINATION 15 Spring Creek South- FEMA/NYSD EC NY Rising • Coordination of ecosystem restoration with resiliency projects in Design Phase • Coordination with partner efforts including Rockaway/Jamaica Bay Reformulation, NY Rising Spring Creek South- FEMA/NYSDEC Howard Beach Community Spring Creek North- USACE/NYC Parks
  13. 13. 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
  14. 14. 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
  15. 15. 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. 19. 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
  20. 20. 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 25 11/2/201 7 WORK IN PROGRESS - SUBJECT TO CHANGE
