Green Infrastructure Portfolio Standard: A Guide to the Green Infrastructure Portfolio Standard And Building Stormwater Retrofits

This report outlines how the green infrastructure portfolio standard (GIPS) can be applied to stormwater retention to determine where retrofits should be installed, how to offset large capital investment costs, and how to protect community water resources. It also includes case studies that have made successful improvements through GIPS. The report recommends cities remove barriers to green infrastructure, set performance-based standards, reduce imperviousness, and establish a stormwater utility and fee system.
