Objective:

Develop an integrated Decision Support Tool (i-DST) that allows for optimization and life-cycle cost assessment (LCCA) of grey, green, and hybrid stormwater infrastructure and is adaptable across the diverse climates and regional policies and practices of the U.S.

Approach:

Build a coupled, integrated decision support tool (i-DST) around a user-friendly interface for site to sewer-shed scale implementation. Coupling of novel as well as existing stormwater tools with advanced LCCA algorithms will provide decision makers with a range of tools that can be implemented to optimize cost and benefits associated with stormwater infrastructure.

Expected Results:

Two explicit tools developed, i-DST and i- DST-SB, for evaluating options and risks associated with improving stormwater runoff management using green, grey and hybrid infrastructure. Ancillary benefits such as reducing inputs to, and costs of, grey infrastructure, as well as enhancing green livable cities and augmenting scarce water supplies will be incorporated within the tools. User and training documentation will be developed as well as regional training workshops. An expert Science Advisory Board (SAB) will oversee and guide development of the operational framework.
