Abstract
The Community-enabled Lifecycle Analysis of Stormwater Infrastructure Costs (CLASIC) tool has been developed to serve as a screening tool utilizing a lifecycle cost framework to support stormwater infrastructure decisions on extent and combinations of green, hybrid green-gray and gray infrastructure practices. The web-based tool is be geographical information system (GIS) interfaced and includes interaction with national databases to upload data for the modeled area, thus removing barriers associated with collection of data to serve as inputs. Three outputs are included to inform decisions on stormwater control measures (SCMs); (1) Hydrologic Performance, (2) Lifecycle Cost, and (3) Co-Benefits. CLASIC is interfaced with the Storm Water Management Model (SWMM) to provide the user with estimates of annual average runoff, infiltrated volume, and volume evapotranspired as well as pollutant load reduction. Life-cycle costs are estimated via construction, maintenance, and rehabilitation costs over a modeled project lifetime. Co-benefits are presented using the Triple Bottom Line (TBL) approach including social, environmental, and economic benefits realized by installation of combinations of SCMs. Scores in each TBL category are linked to hydrologic, water quality, and cost outputs from the tool and informed by multi-criteria decision analysis and user selected preferences. CLASIC has been beta tested by more than 50 potential users and is currently being enhanced to improve usability. The methodology applied by the CLASIC tool will be presented and the tool will be demonstrated.
