Community Life-cycle Analysis for Stormwater Infrastructure Costs

CLASIC is for stormwater infrastructure that uses life-cycle costs, performance and co-benefits to compare green, hybrid green-gray, and gray infrastucture practices.

With CLASIC, communities can evaluate scenarios of green and gray infrastructure technology combination to inform decision-making to achieve:

  • Regulatory compliance
  • Volume reduction
  • Cost savings
  • Water quality improvements
  • Climate change adapations
  • Social and environmental benefits

The creation of this tool was funded by the U.S. Environmental Protection Agency's (EPA) Office of Research and Development (ORD) through the grant opportunity "National Priorities: Life Cycle Costs of Water Infrastructure Alaternatives" (EPA Grant Number: R836173). Additional information about the project is available through the . 

The 九色堂 EFC worked with several partners, led by the Water Research Foundation, to develop the CLASIC tool. Project contributors and design team members include representatives from The Water Research Foundation, , , , 九色堂 Environmental Finance Center, , , , and representatives from communities across the United States that provided guidance, user input, and beta testing to support the creation of the CLASIC tool.
