Objective:
The goal of the Community-enabled Lifecycle Analysis of Stormwater Infrastructure (CLASIC) Platform is to develop a transparent, robust, peer-reviewed, end-user informed and accessible Life Cycle Cost (LCC) framework model for stormwater infrastructure alternatives that can accommodate regional and scale variations to support integrated planning. This will be accomplished through five integrated objectives:
- LCC Framework Model development to develop an integrated, standardized approach.
- Data collection of existing data sources on construction, operations, maintenance, and replacement costs of gray and green infrastructure solutions based on protocols and structure developed under the LCC Model.
- Data analysis and standardization to analyze, standardize, and compile the data collected in a relational database with structure consistent with the LCC/LCA Model that can be used to support tool development.
- Decision support tools that are publicly available in an enduring and enabling platform for use by the urban water community that works easily at scale, fosters innovation, and promotes collaboration.
- Community engagement to ensure all products developed are scientifically sound, accurately reflect community needs, and supported and implemented by end users.
Progress Summary:
A vision of CLASIC decision support system (DSS) is established as follows: “The CLASIC tool will 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 user groups were defined. The expected users of the CLASIC tool include managers and operators of regulated stormwater systems, managers and operators of any unit of municipal government with dedicated funding for stormwater management and consultants to those groups.
The Life Cycle Cost (LCC) framework and life stages align more closely with the types of decisions and analysis relevant to CLASIC target users. This focus emphasizes performance as it relates to a clearly defined geographic area and the reality of both capital and operational budget constraints. LCC assists in understanding how varying allocation of resources across life stages impacts overall performance.
The major differences of CLASIC decision support system from existing tools are:
- The CLASIC tool is hosted on cloud-based platform (eRAMS; https://erams.com/) so that it will be geographical information system (GIS) interfaced and include interaction with national databases to upload data for the modeled area;
- The CLASIC tool has incorporated the rigorous Life Cycle Cost (LCC) framework to integrate institutional context, financing strategies and programmatic objectives, by collaborating with two EPA’s Environmental Finance Centers (EFCs);
- The CLASIC tool integrates Multiple-Criteria Decision Analysis (MCDA) that enables consideration of co-benefits for green infrastructures based on rigorous assessment of life cycle costs and benefits.
A pre-beta version of CLASIC tool was developed. Through community engagement, presentations were given at national conferences and workshops to seek feedbacks from potential users and general public. In summary, there are three integrated components in the CLASIC decision support system: (a) Life Cycle Cost; (b) Performance; and (c) Co-Benefits.
- Three main components to the CLASIC tool outputs are: life cycle costs (LCC), performance of stormwater infrastructure; and results from co-benefits / triple bottom line analysis (TBL). The TBL analysis will be informed via multi-criteria decision analysis (MCDA) output. The MCDA will provide quantitative output to compare co-benefits across scenarios of technology selection and the LCC will inform life cycle costs and considerations of scenarios selected by the user.
- Outputs will also be provided on performance of scenarios in terms of hydrology (e.g., peak runoff and volume reduction) and pollutant load reduction.
- These three components of outputs are intended to work synergistically to inform decisions on scenarios. When a user views outputs, they will have the option to create and refine new scenarios based on knowledge gained from the previous scenario outputs.
Future Activities:
In the next report period, the CLASIC decision support system will be developed, go through beta testing with communities and peer-review process, and ready for public use. The case studies through community engagement efforts will be summarized to demonstrate the application of CLASIC decision support system at different geographic location across the country. The expected results will be increased confidence in comparisons of both the costs and benefits of stormwater infrastructure alternatives by communities.
