Transcript

  • 1. Kingston Waterfront Flooding Task Force: A case study for community-driven flooding adaptation. Libby Murphy Hudson River Estuary Program/Cornell WRI Gregg Swanzey Economic Development, City of Kingston
  • 2. Outline • The Hudson River Estuary Program • Case Study: Kingston Waterfront Flooding Task Force • What can you do? • Municipal perspective from Gregg Swanzey • Wrap up • Questions
  • 3. Hudson River Estuary Program Core Mission • Ensure clean water • Protect and restore fish, wildlife, and their habitats • Provide water recreation and river access • Adapt to climate change • Conserve world-famous scenery
  • 4. Climate Change & The Hudson River Estuary Program • Climate Smart Communities • Flooding Task Forces • Watershed Resiliency • Watershed planning • Green infrastructure • Assessing culverts for correct sizing • Assessing dams for removal or repair • Trees for Tribs (stream buffer restoration) • Biodiversity Resiliency
  • 5. Kingston Flooding Task Force Case Study
  • 6. Current situation
  • 7. Community-driven process
  • 8. Flooding Adaptation Strategies •Fortify •Accommodate •Strategically Relocate
  • 9. Fortify Levee, New Orleans, LA Seawall, Beacon, NY
  • 10. Accommodate Floodable park concept, NYC Elevated structures with flood gates, Hamburg, Germany
  • 11. Local example of accommodation Steelhouse restaurant, Kingston, NY
  • 12. Strategic Relocation Wetland with walkway concept, Toronto, Canada Natural shoreline with gazebo, Cold Spring
  • 13. Simulations
  • 14. E Strand in Kingston Kingston waterfront low tide
  • 15. 4’ of Sea Level Rise Kingston waterfront Simulation: elevated sea level (4’) at low tide
  • 16. Example of Fortify Kingston waterfront Simulation: elevated sea level (low tide), armored protection
  • 17. Example of Accommodate Kingston waterfront Simulation: elevated sea level (low tide), vegetated revetment, floodproofed buildings
  • 18. Example of Strategic Relocation Kingston waterfront Simulation: elevated sea level (low tide), strategic retreat
  • 19. TF uses a variety of tools to reach consensus: • Participatory mapping • Surveys • Dot voting • Vulnerability and risk assessments • Cost Benefit Analysis • CSC planning assessment
  • 20. Flood risk maps
  • 21. Participatory Mapping
  • 22. Cost benefit tool Scenario: damage from a 100-yr (1%) storm in 2100 with high sea level rise. 2013 no sea level rise.
  • 23. Worse case scenario Year 2100, With High Sea Level Rise and a 100-year Storm 1% Probability of Occurrence in Any Given Year Total Damage for this Event: Damage to Wastewater Treatment Plant: $39.9 Million $27.6 Million • Lost Value Due to Sea Level Rise • Lost Value Due to Sea Level Rise + Storm Surge Cumulative Expected Damages by 2100 With High Sea Level Rise = $126 Million
  • 24. What can you do?
  • 25. NYS 2100 Commission Report (2012) NYS Sea Level Rise Task Force Report (2010) Responding to Climate Change in NYS / ClimAID (2011)
  • 26. What else can you do? • Stay in touch with the Hudson River Estuary Program • CanVIS free visualization tool by NOAA • Sea level rise webviewer, Hudson River, by Scenic Hudson (coming soon) • Check out the new Climate Adaptation page on the DEC website (coming soon)
  • 27. Sandy and Irene: two different storms • Irene: extreme rain event • Sandy: extreme storm surge at height of spring tide • The Perfect Storm? Irene plus Sandy
  • 28. Flooding Impacts on the Kingston Waterfront • Sewage Treatment Plant • Marinas and other water dependent uses • Adjacent Businesses • Residential Areas • Parks and other amenities • Structures in the Waterways
  • 29. What can municipalities do? • Assess and manage stormwater • Build community awareness and consensus • Plan for the future • Evaluate Zoning and Code • Work closely with developers and residents
  • 30. Planning for the future in Kingston • Kingston Comprehensive Master Plan • Local Waterfront Revitalization Program • Waterfront Development Implementation Plan • Stormwater Management Plan • Tidal Rondout Watershed Management Plan • Brownfield Opportunity Area and 70 acre GEIS • Kingston Waterfront Flooding Task Force • Hazard Mitigation strategies
  • 31. Funding Mechanisms • Consolidated Funding Application Process • Department of Environmental Conservation • Department of State • Office of Parks Recreation & Historic Preservation • US DOC Economic Development Administration • US DHS FEMA & Hazard Mitigation Funding • USDA • HUD Community Development Block Grants & Low interest loans • Greenway Conservancy • Local Development Corporations & Private Financing
  • 32. Other important activities • Kingston Conservation Advisory Council • Climate Smart Community • Climate Action Plan • Natural Resources Inventory • Open Space Plan • Work with Planning Board
  • 33. Wrap Up • Hudson River Estuary Program • Kingston Waterfront Flooding Task Force • Municipal perspective • What you can do
