In anticipation of Code for Philly's Oct. 16-18 “Apps for Philly Sustainability” meet-up, Philadelphia Water and other City agencies released tons of data for the super-tech savvy crowd to tinker with.

Our hope is this creative community of app-building enthusiasts will come up with new tools that help Philadelphia understand and appreciate, among other things, the breadth of green infrastructure projects being designed and implemented through the Green City, Clean Waters program.

Using the data we’ve collected and shared, they can conceive fun and engaging ways for people explore things like green infrastructure locations, how much rain is falling in different parts of the city, and how the topic of customer phone calls varies from neighborhood to neighborhood.

PhillyInnovates, a blog by the City's Managing Director’s Office, just published this helpful list of the data sets Philadelphia Water released today:

Green City, Clean Waters is the biggest plan in the U.S. designed to manage stormwater with green infrastructure, and that means Philadelphia Water will take all the help it can get from developers who want to add value to their properties while also lessening the negative environmental impacts with green stormwater tools.

On October 8th, Councilwoman Blondell Reynolds Brown, Chair of the Council Committee on the Environment, introduced a bill that would give the development community a new incentive to include one of the most talked about green infrastructure tools out there – green roofs.

Brown’s bill would allow for density zoning bonuses for developers who incorporate approved green roofs into building designs.

"As a City, we have been steadily increasing incentives to build green roofs, and it is working. Philadelphia is now the number three City in North America when it comes to green roof square footage, trailing only Washington, D.C. and Toronto, Canada; that is huge," Councilwoman Reynolds Brown said in statement released by her office.

Green roofs would have to meet Philadelphia Water's design standards to qualify for the density bonus, and Commissioner Howard Neukrug offered support for the new bill.

"We thank Councilwoman Reynolds Brown for helping to provide this added incentive that will create more green roofs in Philadelphia," said Neukrug. "Green roofs help to manage stormwater, keeping it from overwhelming our sewer system and polluting our rivers. This legislation will also help make green roofs more affordable and help create more jobs for our local green business community."

Under the current code, a 10,000 square foot lot in a Residential Multi Family Zoning District (RM-1) would be zoned for twenty dwelling units. If the developer added an approved green roof to the design, the same lot would be zoned for 27 units.

In a Neighborhood Commercial Mixed Zoning District (CMX-2 and CMX-2.5) a 10,000 square foot building is currently zoned for 19 dwelling units and under the new law, would be zoned for 27 units, provided they install an approved green roof.

A green roof is defined by the ordinance as “a treatment to a rooftop that supports living vegetation and includes a synthetic, high quality waterproof membrane, drainage layer, root barrier, soil layer, and vegetation layer.”

Philadelphia would join a small but growing number of cities offering density bonuses for green roofs including San Diego, Portland, Ore., Chicago, and Austin. The bill will be referred to the Committee on the Rules, Chaired by Councilman Bill Greenlee, who expects a fall 2015 hearing.

Mayor Nutter and Dr. Hite join George W. Nebinger students in a ribbon cutting for their green schoolyard on Earth Day 2015.

After years of bringing the benefits of green stormwater features to dozens of Philly schools through our Green City, Clean Waters plan, we’re ready to share what we’ve learned with communities here and around the country. The result? Transforming Philadelphia’s Schoolyards, a colorful, 44-page design guide to greening schoolyards made with the help of the Community Design Collaborative and their ace team of volunteers. 

The pioneering toolkit on schoolyard transformation will be presented on Monday, May 4, 2015 from 5:30 pm to 7:30 pm at the Center for Architecture, 1216 Arch Street. The event will include a panel discussion featuring the leaders of three successful schoolyard makeovers, a green schoolyards resource fair, and opening remarks by Philadelphia School District Superintendent, William R. Hite. Jr. and PWD's Commissioner, Howard Neukrug. And, yes, you ARE invited!

We made this guide because there’s an ever-growing groundswell of communities seeking to reinvent Philadelphia’s mostly asphalt schoolyards as neighborhood spaces that foster learning, connection to nature and community. Transforming Philadelphia’s Schoolyards presents ideas, advice and stories drawn from PWD and the Collaborative’s work to design green schoolyards and manage stormwater—providing on-the-ground experience, case studies and guidance for motivated schools and communities across the city and country to do the same.

Through the Green City, Clean Waters plan, PWD is reimagining stormwater management citywide and sees schoolyards as ideal sites for green infrastructure. When PWD began working with the School District of Philadelphia, it recognized a need for a holistic approach to reinventing the schoolyard, and teamed up with the Collaborative, a non-profit providing preliminary architectural, landscape architectural, and engineering designs that incorporate the voices of schools, neighbors and communities. Having been with us since Green City, Clean Waters started nearly five years ago, the Collaborative's experience made them the perfect partner for this guide.  

Advocates for green schoolyards (including teachers, administrators, students, families, communities, designers, public agencies, and others) will gain inspiration and receive a complimentary copy of the design guide at the event.

You can RSVP for the event here. If you’re interested in making your community’s school a greener, brighter place, we hope to see you there!

Study Shows Evidence of “Triple Bottom Line” Effects of Green Stormwater Infrastructure

Water Fact Infographic

When we started the 25-year Green City, Clean Waters plan in 2011, the idea was that we could better manage our stormwater and reduce combined sewer overflows by leading with green infrastructure, as opposed to only using gray infrastructure, and that it would also have additional social and economic benefits. We call it our “triple bottom line" approach. While the environmental benefits (good news—we’re on track to meet our environmental targets for year five of the plan!) and economic benefits are quantifiable, the social benefits are harder to measure. But a recent study, published this January in the American Journal of Public Health, indicates that the green stormwater infrastructure we’ve installed in Philadelphia does, indeed, have social benefits as well.

The study, led by Michelle Kondo, formerly a postdoctoral student at the University of Pennsylvania's Center for Clinical Epidemiology and Biostatistics and now a scientist with the U.S. Department of Agriculture Forest Service in Philadelphia, looked at 52 green stormwater projects in Philadelphia and found consistent and statistically significant reductions in narcotic possession and manufacture, as well as burglaries near those sites.  

These impressive results caught the eye of the Inquirer’s Sandy Bauers, who featured the study in her regular GreenSpace column

[Kondo] and her colleagues, including Penn epidemiologist Charles Branas, who had studied vacant lots, compared the 52 sites with 186 similar areas where projects were planned but not yet built. They factored in socioeconomic data from the census, crime statistics, and health data.

Their results, published in January in the American Journal of Public Health, were an eyebrow-raiser. Between 2000 and 2012, incidents of drug possession at the project sites dropped by as much as 27 percent compared with the control sites.

As far as a half-mile away, "we saw a significant reduction," Kondo said.

The study controlled for a number of other factors—gentrification, general improvements in quality of life, etc.—that had occurred over the 12 years of the study and yielded a strong positive correlation between the presence of a Green City, Clean Waters project and incidents of drug possession. 

Clearly, there’s still more studying to be done so we can determine links to other improvements in overall quality of life measures and reductions in crime, but these initial results are very promising! Studies like this help demonstrate the return on investment for each individual green infrastructure project and that the triple bottom line approach is truly paying off! 

London Councillor Takes Note of Green City, Clean Waters

In a letter to the editor of The Economist (third one from the top), Councillor Harry Phibbs of London's Hammersmith and Fulham Borough responds to their September article "London's Sewers, Smelling Sweet" about the Thames Tideway Tunnel. He makes a point about using green, natural stormwater infrastructure solutions by referencing Philadelphia’s “better, cheaper alternative of green infrastructure that soaks up the rainwater in various ways to stop it causing sewage overflows in the first place.” Of course he's referring to Green City, Clean Waters. (We guess this glowing praise means they’ve gotten over the role
Philadelphia played in that whole revolution thing.)

Here at PWD, we think any investment in infrastructure is worthy and applaud
London’s commitment to reduce sewage overflow into the Thames. In fact, we’re making similar investments in “hard infrastructure” with projects like the recently completed stormwater storage basin unit at Venice Island while also continuing our commitment to green infrastructure. It doesn’t necessarily have to be an “either or” choice. We can (and should) make investments in new pipes as well as new green stormwater infrastructure like tree trenches and rain gardens.

With that said, we are proud of the triple bottom line approach of Green City, Clean Waters. Investment in green infrastructure provides benefits that go beyond simply reducing combined sewer overflows--it also creates social benefits and is good for the economy. For every dollar we spend, we want to provide the biggest return and benefit to the public as well as the environment. Our hope is that green infrastructure, unlike "hard" or "gray" infrastructure, creates a system that will last as long as nature itself. Thanks to Councillor Phibbs for recognizing us for it!

5 ways PWD aims to be a model 21st Century urban water utility

To start off our series about points from the budget testimony PWD delivered this week, we wanted to share a couple of quick pieces for background—our mission and our short- and long-term goals.

PWD mission:
PWD aims to be America’s model 21st Century urban water utility- one that fully meets the complex responsibilities and opportunities of our time and environment. PWD’s mission is to:

  • Provide the Greater Philadelphia region with integrated water, wastewater and stormwater services
  • Protect public health by always delivering PWD’s customers the highest quality of drinking water at a competitive and affordable cost
  • Protect the environment by managing and treating the region’s wastewater and stormwater, protecting and advocating for rivers and streams and their watersheds, and protecting sources of drinking water
  • Support the sustainable growth of Philadelphia and its residents, communities, businesses and industry as well as the financial well-being of the utility
  • Continue to be America’s most innovative utility with a constant focus on quality, efficiency, customer service and affordability

We just LOVE that we’re getting to support sustainable growth as the city’s population continues to be on the rise! The key, as we say, is making sure that growth is smart and sustainable so it also allows us to protect the environment for the next several generations of Philadelphians.

How do we plan on fulfilling this mission? Check it out:

PWD’s short and long term goals:
PWD recently completed a new Strategic Plan, which was created with the input of PWD’s own staff, other city and government agencies, and external partners. The plan focuses on eight key areas:

  • Improve customer service, outreach and assistance
  • Increase workforce strength and diversity
  • Improve our financial health
  • Invest in capital planning
  • Protect our infrastructure
  • Uphold excellence in core services
  • Ensure sustainable utility operations
  • Support a strong and diverse Philadelphia business community

It’s no accident that improved customer service is at the top of the list. It is a top priority for PWD and a place where we’re always striving to get better. Friday we’ll share some more details about how we plan to do this.

Penn State Students Work on Green Stormwater Infrastructure Projects

Saturday, October 5, Penn State students and volunteers helped restore two green stormwater infrastructure projects –a rain garden and a stormwater bumpout-- on Lancaster Avenue. “The two sites we worked on weren’t functioning properly. So we fixed them, prettied them up, mulched, planted — the whole shebang,” said Tommy McCann, an urban agriculture coordinator and horticultural educator at Penn State.

The idea for the volunteer day began when organizers from Penn State met with the Philadelphia Water Department to discuss possible partnerships and to tour stormwater infrastructure sites that PWD had plans to improve, including the rain garden and bumpout on Lancaster Ave. This cleanup day is part of a bigger initiative by Penn State Public Media to produce a documentary that tells the story of how cities acrossthe United States are learning to manage stormwater with green infrastructure. PennState plans to release the film, Water Blues Green Solutions, in late 2013.

Julian Abele Park Grand Reopening

Julian Abele Park: Ribbon Cutting and Grand Reopening from Philadelphia Water Department on Vimeo.

Love your Park week came to a close on Saturday, May 18th with events and festivities around the City. One of these events was the grand reopening of Julian Abele Park in the Graduate Hospital neighborhood. Check out this short video of Shelly Jones, a PWD engineer, speaking about PWD stormwater improvements at the event last weekend. Also, check out Naked Philly’s pre-game coverage for some great photos.

The park has undergone a number of improvements including innovative stormwater management work led by PWD as part of Green City, Clean Waters. The stormwater projects include tree trenches in the sidewalks adjacent to the park with paver accents to match the park's interior design. The tree trenches are designed to manage approximately the first 1.3 inches of rain during a storm. This means that runoff from more than half an acre is managed on site, reducing pollutants that end up in our rivers and streams by keeping stormwater out of the sewer.

City agencies and community advocates worked together to complete the various park improvements including the Department of Public Property (DPP), Parks and Recreation (PP&R), the Pennsylvania Horticultural Society (PHS), and the Friends of Julian Abele Park. Work was funded through neighborhood fund-raising and a grant from The Pennsylvania Department of Conservation and Natural Resources (DCNR). 

It’s a Wrap! Congratulations to our Rain Barrel Artists

With over 800 votes, the results for our Rain Barrel Wrap contest are in! Congratulations to the top three winners: Philly Pride, Cats and Dogs and Liquid Motion.

Students between the ages of 11 and 21 from Laura W. Waring School and YESPhilly participated in a design workshop with artists from the Mural Arts Program and educators from Fairmount Water Works Interpretive Center and the Philadelphia Water Department to create exciting original artwork that will be wrapped around a limited number of rain barrels. We hope this artwork will help bring attention to small actions in stormwater management (like installing a rain barrel) that can make a big difference.

Thanks to everybody who voted to help select the top three student designs. You are invited to the Fairmount Waterworks Interpretive Center for the Water Department and Mural Arts dedication where we’ll recognize the winning artists. The dedication is scheduled for Thursday, March 14th at 4:00 p.m. right behind the Museum of Art on the Schuylkill River in the Fairmount Water Works Interpretive Center at 640 Water Works Drive. Please send RSVPs to


Philly Pride by Titus Edwards (YES Philly)

Philly Pride

Titus’ idea for this design came from a classroom conversation about pride in Philadelphia. For him, pride in the City comes from the people in his community. He chose the typical rowhomes of ordinary people as a symbol of Philadelphia community pride.

Cats and Dogs, a class collaboration

Cats and Dogs

This design is a playful interpretation of the old saying, “It’s raining cats and dogs!” Students created a whimsical image by using bold colors and drawing a variety of cats and dogs.


Liquid Motion, a class collaboration

Liquid Motion

For this design, students chose blues and greens to represent water. They mixed these colors with glue, let them dry and photographed them against a light, giving the photographs a water-like translucency.
