Kingston Waterfront Flooding Task Force: A Case Study for Community-driven Flooding Adaptation

Published on

Extreme weather is becoming more common in our region. Flood events can impact human health and safety, and result in substantial costs to property and infrastructure. Geared toward municipal decision makers and concerned citizens, this forum provides on-the-ground examples of flood resilience strategies that can help Hudson Valley communities minimize risks while conserving financial resources.

Presentation by Gregg Swanzey, Director of the Office of Economic Development and Strategic Partnerships, City of Kingston and Libby Murphy, Climate Outreach Specialist,
Hudson River Estuary Program, NYSDEC for a flood management forum hosted by the Cary Institute of Ecosystem Studies in Millbrook, NY on May 4, 2013.

  • Now I will take you through a case study of how one community is looking at building its resilience through adapting to flooding.
  • Hurricanes Irene and Sandy focused our attention on flooding risks in NYS. Right here in Kingston we have serious flooding risks along the waterfront. Here is a photo from Irene, you can see the maritime museum and the steelhouse.Point out Rondout, HR, street. Not just riverfront but waterfront. Applies to tributary communities.
  • So what they done is create a Flooding Task Force, which comprises a diverse group of stakeholders, residents, business owners, developers, to develop a vision and strategy to protect the future of their waterfront community. The HREP has partnered with SH, CBI, DEC OOCC and DOS to assist in this process. Our job is to educate the TF on the hazards and lead them through a process of analyzing the risk and finding solutions.Community-drivenUsing various tools: participatory mapping, DOS, CBA
  • Once they understand the risks they can start to imagine solutions. In general, you can think of three overarching adaptation routes: you can protect, accommodate, or retreat. Which strategies you choose will be determined by the values and goals of your community. Think about issues like economic development, recreation, security and ecological resources.
  • Protecting means building hard barriers between you and the water. This has been the majority of our flooding solutions in the past. The problem is, they only protect up to a certain point and can lead to a false sense of security. This is a levee in NOLA.Is this really Beacon?
  • Accommodate means living with the water and reducing its impact. Here is an example of a permeable park that allows water storage and inundation. On the right is the riverwalk in Tarrytown that is designed to flood but also allows for human enjoyment and recreation along the river.
  • This is an example of flooding accommodation right here in Kingston.
  • Finally, there is strategic retreat where people move built spaces out of the high risk flood zones. This is happening now in Staten Island where whole communities are accepting buyouts to relocate.Is that pic from Cold Spring?
  • This is the same stretch of buildings as in the CBA model
  • Bulkhead. Expensive, may eventually be overtopped
  • Vegetated revetment, floodproofed buildings.
  • You can imagine a scenario where damage has become so costly and repetitive that relocation makes economic sense. Notice higher elevation homes in the back. This can still become a recreational destination and provide economic benefits.
  • One tool is mapping. Here is a map of the flood risk areas in Kingston and how they will increase over time. This map was made by SH.The dark areas show what will be submerged first, with lower SLRYellow shows 100 yr floodplainsPoint out WWTPSH is creating a webviewer of all communities on the HR
  • Results of Participatory Mapping, tells a story.
  • Scenario: damage today from 100-yr flood. Remember, Sandy was worse than the 100-yr storm.This tool uses the DDF – depth damage function from Army Corps, takes historical insurance data by building type.Remember, this is GoogleEarth so we’re looking at building roofs.We would expect that the buildings and parks nearer the water be more damaged. Not surprising that a parking lot farther back has relatively low damage.
  • We are also using a CB tool called COAST. This is a worse-case scenario for Kingston. This shows the damage from future SLR and Storms in 2100.Can anybody guess what the tower is?You can see that the cumulative damage from now until 2100 is well over $100M. Think about the value of being able to quantify this. This is one way to get people to act, show them how much we have to loose.
  • These are also concerns for tributary communities.RHR info?Three reports, climAID chapter on waterClimate Smart CommunitiesFree CanVIS software from NOAARevitalizing Hudson RiverfrontsTool by SH
  • Check to see if you community has taken the CSC pledge. This will provide tech assist and funding in the future.
  • Check out these three reports! They’re free online
  • Read through the recommendations outlined in RHR from SH. Excellent resource.Talk to HREP for guidance on stormwater management, climate adaptation, biodiversity resilience and more!Download the CanVIS free visualization tool by NOAA. Also there is going to be a SLR webviewer for the HR communities by SH that will be up soon.
  • Talk to HREP for guidance and opportunities on stormwater management, climate adaptation, biodiversity resilience and more!
