Triple-bottom-line assessment of stormwater quality projects: Advances in practicality, flexibility and rigour

Abstract

Decision-support frameworks that help users to consider financial, social and ecological costs and benefits (i.e., 'triple-bottom-line' decision frameworks) are increasingly being used by water managers. This paper describes the outcomes of a project that was undertaken to assist stormwater managers to complete triple-bottom-line assessments of proposed urban stormwater quality management measures. The primary outcomes have been: a set of guidelines that clearly define a twelve step assessment process; and the results of a trial that was used to test and refine the guidelines in Brisbane, Australia. A brief overview of the twelve step assessment process is provided. The strengths and weaknes..
