Municipal Resilience Planning Assistance for Sea Level Rise, Coastal Flooding, Wastewater Treatment Infrastructure, and Policy

About the Project

(anticipated completion date: May 2018)

With a grant from the Connecticut DEEP, UConn CIRCA will develop tools (methodologies and data) for municipalities in counties affected by Superstorm Sandy for the assessment of vulnerability of infrastructure (including waste water treatment plants, pump stations, roads, and public safety assets), to inundation by river flow and storm surge, now, and in the next 25 to 50 years, when it is likely that sea levels will be higher and precipitation statistics different; and provide policy and financing options for resilience projects for Connecticut’s municipalities. Additionally, the use of these products will be piloted in communities. UConn CIRCA will produce the following products as a result of this project:

  • Sea level rise projections for Long Island Sound
  • Models and maps of the combined impacts of riverine flooding and storm surge
  • Models and maps of inland flooding under current future climates
    • 20%, 10%, 5%, 2%, and 1% annual chance flood inundation from storms
    • Evaluation of extreme future climate storm scenarios (category II hurricane) against the current 1% (100-year) and 0.2% (500-year) flood inundation levels
  • Vulnerability assessment process for wastewater treatment plants
  • Policy and financing options for resilience projects that may be effective in Connecticut based on a survey of municipal needs


A public meeting was held on October 19, 2017 at UConn Avery Point with Dr. O'Donnell's Sea Level Rise findings.
