Many communities are addressing stormwater management needs and assessing requirements for implementing management plans. Some considerations during this process include costs associated with aging water infrastructure conveyance systems, the addition of green infrastructure controls, rate payer expectations, and other considerations important to the community. This presentation will feature the recently completed Community enabled Lifecycle Analysis of Stormwater Infrastructure Costs (CLASIC) and Triple Bottom Line (TBL) Benefits tools. The web-based GIS interfaced CLASIC tool utilizes a life cycle cost framework to support feasibility and planning of stormwater infrastructure at a municipality or watershed scale, with case studies spanning all climate regions in the U.S.  Furthermore, this presentation will demonstrate how the CLASIC and TBL Benefits tools can help understand and weigh the estimated life cycle costs, reductions in stormwater runoff and pollutant loads, and co-benefits of various planning scenarios as they consider stormwater management projects, including under future climate scenarios.
