The life cycle costing (LCC) module for distributed stormwater control measures (SCMs) for the integrated decision support tool (i-DST) supporting analysis of green, grey, and hybrid stormwater infrastructure deployment in urban settings in the United States is an Excel workbook that allows for planning-level evaluation of costs and first-order environmental impacts of stormwater infrastructure. The LCC module provides inputs to the broader i-DST to enable cost-based analysis. Additionally, the LCC module is a standalone workbook and can be used independently. The data include an Excel-based life cycle cost model for distributed stormwater control measures and its user guide. This model is a module of the broader Integrated Decision Support Tool led by the Colorado School of Mines (https://idst.mines.edu) in collaboration with researchers at UC Berkeley, South Dakota School of Mines, Georgia Tech, and The Nature Conservancy. The purpose is to support customizable analysis of life cycle costs associated with distributed stormwater control measures in the United States, including a first-order estimate of environmental costs. The model includes various scenario analyses, including the ability to adjust the base year of analysis, but is based primarily on data available in 2018-2019.
This model was developed under a subaward of Assistance Agreement No. R836174 awarded by the U.S. Environmental Protection Agency to the Colorado School of Mines, the Nature Conservancy, and the University of California-Berkeley.
