A set of spreadsheet tools help users identify and combine capital costs and ongoing maintenance expenditures in order to estimate whole life costs for stormwater management. The models provide a framework for calculating capital and long-term maintenance costs of individual best management practices and low impact development techniques. Models are included for: retention ponds, extended detention basins, swales, permeable pavement, green roofs, large commercial cisterns, residential rain gardens, curb-contained bioretention, and in-curb planter vaults. Published by WERF. 32 pages. Online PDF of user's guide and spreadsheet tools. (2009)
