Accounting for Uncertainty in Determining Green Infrastructure Cost-Effectiveness
Economic Incentives for Stormwater Control
2012
Abstract
As was mentioned in the last chapter and in others before it, uncertainty
about the effectiveness of low-impact development practices and green
infrastructure as stormwater runoff control measures is an area of research
focus. In this chapter, the analysis is taken a step further by linking the
uncertainty in green infrastructure (GI) effectiveness with uncertainty

that is inherent in GI costs and municipal implementation programs. The
chapter demonstrates that in order to make GI a central component of their
infrastructure programs and land use plans, municipalities, water utilities,
and other natural resource planners need to better account for such uncertainty. Because GI programs involve landscape-scale assessments and
stakeholder participation, traditional infrastructure decision-making processes do not easily apply. Instead, a ,ve-step modeling approach is outlined that integrates the uncertainties in hydrological, economic, and key
stakeholder interests and perspectives to provide the policy makers with
information that best enables them to evaluate tradeoffs in risk and cost.
