Second in the EYAWTKA series. This post is an annotated and tightly edited list of resources on green infrastructure that I don’t think you can find all in one place anywhere else. It began just as some reminders to myself and then I figured maybe others might find it useful. It’s far from comprehensive but it is highly selective – for every link here, many less optimal ones were weeded out. Specialists may want to skip to the BMP tools and databases farther down.
Green infrastructure is a set of methods for cities to prevent flooding and water pollution by using nature instead of fighting it. It’s a subset of what is often called Best Management Practices or Low-Impact Development. Sometimes it’s called nature-based-solutions or sponge city because it’s about soaking up rainwater.
This represents years(!) of struggling to find introductions to green infrastructure targeted to people who don’t know what it is, yet who need more than just an article. There are very few good images of green infrastructure out there which is maddening because it’s hard to visualize if you don’t already know what it is. So I made sure to find sources with excellent visuals.
The Value of Green Infrastructure: A Guide to Recognizing Its Economic, Environmental and Social Benefits. Center for Neighborhood Technology.
Greening DC Streets. A Guide to Green Infrastructure in the District of Columbia. Washington D.C. Department of Transportation.
A Homeowner’s Guide to Stormwater Management. Philadelphia Water Department.
Special mention for pointless deletion of a good resource: The City of Seattle used to have a page of virtual tours where residents showed the raingardens they had built in their own yards, but they deleted it. Screenshots:
Interactive green infrastructure maps
Special mention for pointless deletion of a good resource #2: You used to be able to click on each raingarden on the NYC map and pull up a photo. That’s gone now.
Philadelphia – Green infrastructure map
Philadelphia – two wonderful story maps that masterfully integrate ecological walking tours and environmental history with green infrastructure (Cobb’s Creek) and restoration of a degraded stream (Morris Park)
Portland – This is a map of the Green Street Stewards program where residents adopt curbside raingardens and apparently not a map of all the green infrastructure.
Projects for schools and students
Rain gardens – complete instructions for schools, scout and community groups etc. on how to plan and build one. Rhode Island Department of Environmental Management.
A Guide to Stormwater Management on School Campuses. Projects for K-12 students, everything from raingardens to wildflower meadows to vehicle washing. Phildelphia Water Department.
City Habitats: Transform your community to turn the tide on polluted runoff. Brief but excellent booklet for around grades 5-6 packs the science and activities into just eight pages. Was an insert in the Seattle Times newspaper
There are hundreds of lesson plans on green infrastructure and stormwater for K-12 and adult education and outreach out there, on top of the countless others on many other water topics. I don’t claim to have surveyed them all but I don’t think you can go wrong with these two expansive sources with myriad offerings of lesson plans, videos, projects, and teaching aids; and one terrific sewer model.
Sewer in a Suitcase. Sheer genius. I love this. Just what it says – a model of a combined sewer using actual water, in a suitcase, suitable for all ages. Center for Urban Pedagogy, New York.
Teachengineering.org – many, many lesson plans on every aspect of water management, from University of Colorado
“Rain to Drain” and many more lesson plans at Penn State Extension.
Raingardens – how to build and maintain, for private citizens
How to build a raingarden. Extensive resources at Washington State University.
Guidance Manual for Homeowners: Managing Stormwater Runoff Using Green Infrastructure. This one really walks you through with step-by-step photos. Stormwater Coalition of Albany County
Raingarden Stewardship Program Maintenance Manual. This is for residents who volunteer to maintain sidewalk raingardens owned by the city (“right-of-way bioswales”). NYC Department of Environmental Protection, Harbor Protectors program.
Green Streets Steward Maintenance Guide. Another guide for citizen stewards. City of Portland Environmental Services.
Training and support for green infrastructure construction in Korean, Somali, Tigrayan, Cambodian, Chinese, and Spanish for contractors. Seattle Public Utilities.
Case studies – descriptive
If you just want to see examples of green infrastructure, look here.
Detroit – This is one good because you can filter by type of structure
Urban Resilience Briefs from Urban Land Institute. Only partially on green infrastructure
Case studies – comprehensive database and performance reports
International Stormwater BMP Database – Out of all the resources on this page this is the real powehouse, a comprehensive, exhaustive and sophisticated database of quantitative performance data for over 700 BMP installations in several countries. Generates reports and interactive graphs of research results of every site.
Green Infrastructure Wizard (GIWIZ) – Guided search aid for finding reports, case studies, local regulations and planning guidance, modeling software, databases, funding programs, and videos. Huge. I find it easiest to click on “Explore” > “What resources are you interested in?”
Penn State Center for Green Infrastructure and Stormwater Management – Applied research on cutting-edge topics such as cognitive and institutional barriers to the adoption of green infrastructure; visualization tools in green infrastructure decisionmaking, and citizen preferences in non-hydrological benefits of green infrastructure.
BMP selection tools and calculators
All of these are tools for selecting BMPs including but not limited to green infrastructure and modeling their estimated performance and/or cost. As selection tools they are not intended for the design itself.
This is the only spatially explicit one: you draw your site on a map, selected your desired BMPs, and enter the percent of the stormwater you want each one to capture. The tool then calculates the performance and cost based on that site’s topography, precipitation, soil and cover type. (EPA)
Allows specific pollutants and site constraints to be entered as search filters. Reports operating costs, maintenance requirements, lifespan, performance data and construction tips for each BMP. (Interstate Technology and Regulatory Council)
Calculates costs and benefits of various BMPs. The least technical and specialized of these tools. (Center for Neighborhood Technology)
Requires ArcMap. Identifies potential suitable locations/areas for implementing different types of BMPs based on site suitability criteria such as drainage area; slope; hydrological soil group; groundwater table depth; and road, stream, and building buffers.
Models the reduction of inputs of nutrients and contaminants by green infrastructue, and fate and transport of water, nutrients, and toxics across multiple spatial and temporal scales. (EPA)
For lifecycle cost-benefit modeling. (EPA / Water Research Foundation)
Comprehensive stormwater modeling tool used worldwide since 1969(! – with continual updates of course). Not specifically focused on green infrastructure. Included here because of its importance.
