Several organizations have developed new resources to help communities use green infrastructure principles in stormwater management decisions. Green infrastructure mimics the natural water cycle and brings multiple benefits to communities, including habitat, aesthetic, and water quality improvements, in addition to managing stormwater runoff.

The Metropolitan Water Reclamation District has updated its Technical Guidance Manual to help communities comply with the recently updated Watershed Management Ordinance. The ordinance establishes uniform, minimum stormwater management regulations in Cook County that include volume control. The new volume control standards and specifications will help streamline the use of green infrastructure such as bioswales, green roofs, rain cisterns, and permeable pavers.

Also, the Delta Institute has released a green infrastructure toolkit of scalable tools and design templates to help planners, municipal managers, and decision makers overcome technical barriers in implementing green infrastructure. The report helps identify opportunities for implementing green infrastructure and how to make informed decisions based on cost. It also includes a decision support flowchart, along with downloadable templates for bioswales, rain gardens, stormwater planters, permeable pavement, and underground storage.

Finally, Center for Neighborhood Technology (CNT) has expanded its RainReady website with a brochure, case studies, and descriptions of its services. RainReady Home assesses homeowners' flood risk by examining living spaces, foundations, and yard function to help homeowners prevent future flooding. RainReady Community provides a neighborhood-wide risk survey and assessment that also offers financing and implementation guidance to spur practical neighborhood improvements.  CNT also offers an introductory workshop to participating communities.

CMAP's current stormwater management activities include working with the Calumet Stormwater Collaborative, helping communities understand the implementation process for stormwater utilities, and incorporating stormwater management into the CMAP Local Technical Assistance program.
