GreenPlan-IT Toolkit User Guide. SFEI Contribution No. 958. San Francisco Estuary Institute: Richmond, CA.2015.
Structurally, the GreenPlan-IT is comprised of three components: (a) a GIS-based Site Locator Tool to identify potential GI sites; (b) a Modeling Tool that quantifies anticipated watershed-scale runoff and pollutant load reduction from GI sites; and (c) an Optimization Tool that uses a cost-benefit analysis to identify the best combinations of GI types and number of sites within a watershed for achieving flow and/or load reduction goals. The three tool components were designed as standalone modules to provide flexibility and their interaction is either through data exchange, or serving as a subroutine to another tool. This user manual addresses each of the tools separately, though they are designed to complement each other.

Green infrastructure (GI), such as permeable pavement, rain gardens, tree-well planters, or bioswales, can be used as cost-effective, resilient approaches to managing stormwater at its source while delivering environmental, social, and economic benefits for your community. GreenPlan-IT is a versatile open-source toolset that helps aid municipalities with their efforts to plan and evaluate the placement of green infrastructure in the landscape and track the effectiveness of these installations in reducing stormwater run-off, PCB, and mercury in receiving waters.
