Applying portfolio standard concepts for green infrastructure stormwater retrofits.
The Green Infrastructure Portfolio Standard (GIPS) is an adaptation to stormwater management of the “renewable energy portfolio standards” adopted by many U.S. states.
In the case of the GIPS, an urban municipality with a significant amount of impervious surface gradually scales up the use of green infrastructure, increasing the volume of stormwater runoff and pollutants retained on-site and reducing the amount flowing into the stormwater sewer sys- tem and surface waters. By doing so, the GIPS approach not only advances the water quality objectives of the Clean Water Act, but it is also a useful tool for community-scale green infrastructure planning and prioritization over a period of decades.
As part of the project the standard was implemented in Milwaukee, WI and Grand Rapids, MI.
