The story of Living with Water in New Orleans and the UC's involvement with stormwater management.
In recent times, stormwater management in New Orleans has been characterized by regularly overwhelmed drainage systems, excessive paving and pumping that has depleted groundwater levels and led to a sinking city, and urban water assets being wasted while hidden behind walls, underground, or pumped into the river and lake. All of these issues and the failure of traditional infrastructure (levees, pipes and pumps) to protect the city from Hurricane Katrina, continuous flooding, and subsidence has led to a shift in mindset regarding the most effective and thoughtful way to manage stormwater in South Louisiana. It is clear that the single-minded approach of rushing stormwater over pavement, into pipes and pumping it out of the city needs to be reevaluated.
In September of 2013, Waggonner & Ball Architects released the Greater New Orleans Urban Water Plan. The plan was a result of the Dutch Dialogues and the culmination of the collaborative efforts of officials, professionals, advocates, and community members who began to question current practices while taking a serious look at the place of natural processes in the urban environment. The GNO Urban Water Plan calls for a tandem approach to stormwater management that utilizes natural processes to decrease reliance on and take pressure off of grey infrastructure systems, while celebrating the region’s abundant water resources.
Natural processes slow, store and filter stormwater where it falls, allowing it to return to the groundwater system. Natural process based solutions are commonly known as stormwater BMP’s and/or “green infrastructure” and include systems such as canals and waterways, rain gardens, permeable pavement, floating streets, retention ponds, constructed wetlands and other bioretention systems that slow, store and filter stormwater. Programs underway in cities such as Seattle, Portland and Philadelphia are prime examples of the potential held by these sorts of solutions.
Since the release of the Water Plan, momentum has begun to build here in New Orleans and many organizations around town working to promote sustainable stormwater management:
Non-profits such as Global Green, Parkway Partners, Water Works, and the Urban Conservancy are working to educate the public (including public officials) and implement exciting programs around the city.
Local government is contributing to large-scale green infrastructure implementation. Sewage and Water Board’s Green Infrastructure RFP 2014 is funding 7 initiatives whose focus is stormwater management and will invest $500,000 a year up until 2018 for a total of $2.5 million invested in green infrastructure projects. Article 23 places stormwater management requirements that emphasize BMP’s on all new commercial developments in Orleans Parish that are over 10,000 sq. ft.
On September 26, 2014, the GNO Urban Water Collaborative held its inaugural press conference on the banks of Bayou St. John in Mid-City. The collaborative represents one hundred organizations working together to address critical water issues throughout the region and the sort of collective effort that will necessary to move New Orleans towards the more “safe, sustainable and beautiful future” outlined by the Urban Water Plan.
Supporting sustainable stormwater management in New Orleans can be achieved through large scale infrastructure and small scale interventions on private properties.

The Urban Conservancy and their partners in the Umbrella NOLA project were featured in Grist recently. The Hoffman Triangle in Central City is one of many New Orleans neighborhoods that experiences regular localized flooding. Umbrella, a coalition of green-sector nonprofits that includes the Urban Conservancy, ThriveNOLA, Green Light New Orleans, and SOUL NOLA, works to alleviate these localized flooding issues with residential interventions, in partnership with residents and faith leaders.
“You can do two things at once. You can create space for water to go, and, if you’re thoughtful about it, you can create space within society for people who are being shut out economically.”
-Dana Eness, Executive Director of the Urban Conservancy
What should Louisiana do with $6-9 billion in infrastructure funding? The Urban Conservancy and some other local nonprofits believe that green infrastructure is the answer.
We’ve given a lot of thought to this, after Katrina and in the Urban Stormwater Plan. We have a lot of shovel-ready projects. Hopefully we will see an acceleration of those projects that are already in the pipeline.
-Dana Eness, Executive Director of the Urban Conservancy
For the uninitiated, long time St. Charles fixture Avenue Pub has been working on a block-wide project, funded by a healthy mixture of nonprofit partners, grant makers, neighbors, and the pub owner herself. The project is designed by Dana Brown Associates and aims to remove over four-thousand square feet of concrete. Several forms of green infrastructure will be added, and the project has a projected storage capacity of 28,000 gallons of water.
The Water Runoff event will be held in person Nov. 30 at the Broadside.
At least four of eight New Orleans City Council runoff candidates will meet in person Nov. 30 for a policy-driven debate focusing on topics including green infrastructure, stormwater drainage and flooding, coastal restoration, hurricane protection and Sewerage & Water Board water shut-offs. Another City Council candidate who won election outright will also speak at the event, which will be held at the Broadside from 5:30 to 7:30 p.m. The debate is hosted by the Water Collaborative of Greater New Orleans, Urban Conservancy and Coalition to Restore Coastal Louisiana, and it is sponsored by National Wildlife Federation.
Three women who lead New Orleans-based nonprofits will moderate the debate. They are: Jessica Dandridge of the Water Collaborative of Greater New Orleans, Dana Eness of Urban Conservancy and Kim Reyher of the Coalition to Restore Coastal Louisiana.
“Everybody should be here because water impacts every aspect of our lives,” said Dandridge. “Whether you’re focused on safety, criminal justice, education, food justice or any other issue, water is at the center of it.”
The Broadside is located at 600 N. Broad Street in New Orleans. The debate will be from 5:30 to 7:30 p.m. on Nov. 30. Doors will open at 5 p.m. The event is open to the public and media. Food and drinks will be available for purchase. To attend, register here.
“As record-breaking heat waves sweep the United States, New Orleans Mayor Latoya Cantrell has committed New Orleans to a global initiative to expand urban green space, with a goal of cooling the city and reducing flooding. Her pledge, on the heels of New Orleans’ fifth wettest spring since 1871, comes as climate data portends progressively warmer and wetter weather in the decades to come.
Cantrell joined 30 other mayors who signed onto to New York-based nonprofit C40’s latest international declaration to adapt to climate change. The declaration requires participating cities to ensure that 30% to 40% of their built-up surface are covered in green or permeable spaces by 2030. Currently, New Orleans sits at about 20%, said Rebecca Ilunga, C40’s water security network manager…”
NEW ORLEANS – Jerusalem Baptist Church and Stronger Hope Baptist Church, both located in New Orleans’ Hoffman Triangle neighborhood, have completed the installation of permeable paving and green spaces designed to reduce flooding during heavy rain events.
Work on the Jerusalem project was completed by Thrive Works Green, a nonprofit workforce training program.
“Our program is truly one of a kind,” said Chuck Morse, Thrive executive director, in a press release. “We use a holistic approach, walking alongside our trainees before, during and after the program to ensure their needs are met, whether it’s with a weekly stipend, soft skills, mental health support, etc. After they graduate, we connect them directly with contract opportunities.”
New Orleans, LA, September 24, 2020 — Since Katrina, New Orleans leaders have looked for innovative ways to relieve pressure on the city’s pumping systems during storms and other heavy rain events. Many are advocating for more “green stormwater infrastructure” that will allow the ground to soak up water that would otherwise be sent to catch basins.
Unlike curbs, gutters and drains that move stormwater from a built environment into a nearby body of water, green infrastructure is designed to capture the rain water where it falls. Picture an impermeable parking lot, for instance, that’s been converted into one built with a permeable paving system on top of soil that has been conditioned to enhance its ability to take on water. If you’ve been to Parkway Bakery and Tavern near Bayou St. John, you can picture what it looks like.
A lot of people – from the federal government down to local contractors – have been getting involved in GSI projects. The Greater New Orleans Foundation, the Sewerage and Water Board and the City of New Orleans are collaborating on a campaign called “Every Drop Makes a Difference.” The Gentilly Resilience District, meanwhile, will use a $141 million federal grant to create water features, permeable sidewalks and other water-management infrastructure.
One local nonprofit that’s focused on residential GSI projects is the Urban Conservancy, which just released a report on its Front Yard Initiative based on survey responses from 68 of the homeowners who have participated in the program. In five years, the initiative has raised approximately $100k from the Greater New Orleans Foundation, the Wisner Foundation and other benefactors and used the funds to pay a portion of the cost of residential GSI projects citywide.
Urban Conservancy’s Dana Eness said the good news is that the study shows that “green stormwater infrastructure actually works,” and the functionality only increases over time as plants and their root systems have become fully established.
September 2020– Read the Front Yard Initiative’s (FYI) report, published September 2020
FYI’s 2020 Green Stormwater Infrastructure Homeowner survey findings demonstrate that homeowners can significantly decrease flooding on their properties while reducing runoff to storm drains by removing impermeable pavement and installing green stormwater infrastructure (GSI).
The Urban Conservancy (UC) surveyed FYI participants who completed their gray-to-green projects from 2015 to December 2019 to assess the long term benefits and issues with residential GSI. Of the 78 eligible respondents 68 completed the survey (or 86%).
The results of this study support the notion that GSI has many beneficial effects: reducing localized flooding, beautifying outdoor space, bringing back lost habitats, stimulating local economies and more. FYI participants have even reported compounding effects; as their rain gardens and native plants grow in they continue to see greater benefits.
“This data has incredibly positive implications for New Orleans as we continue to look for ways to reduce the risk to people and property that comes with our increasingly intense rainfall events,” says Dana Eness, Executive Director of the Urban Conservancy. “It shows that residential GSI, when properly installed, is effective, economical, not overly burdensome to maintain, and enhances community safety and quality of life by reducing frequency and severity of flooding while keeping thousands of gallons of water per rain event out of our streets, catch basins, and pumping system.”
FYI strives not only to incentivize homeowners to remove impermeable pavement, but also to advocate, inspire and to help guide New Orleans into a more sustainable future. It is our hope and our goal that this report may bring a greater understanding and awareness of the importance of GSI on residential properties and that this in turn increases the implementation of GSI. We want to thank all of our FYI participants and green sector contractors for their indispensable help in bringing New Orleans that much closer to a green future!
NEW ORLEANS, LA, July 20, 2020 –– Homeowners, contractors, and green sector specialists join the Urban Conservancy Tuesday, July 21, at 5:30 pm for a Zoom call to release new survey findings demonstrating that homeowners can significantly reduce flooding on their properties while reducing runoff to our catch basins by installing green stormwater infrastructure (GSI) like rain gardens, rain barrels, and permeable paving systems.
The UC conducted a survey of 68 homeowners who participated in their Front Yard Initiative between 2015 and 2019 to assess long term benefits and issues with residential GSI. “This data has incredibly positive implications for New Orleans as we continue to look for ways to reduce the risk to people and property that comes with our increasingly intense rainfall events,” says Dana Eness, Executive Director of the Urban Conservancy. “It shows that residential GSI, when properly installed, is effective, economical, not overly burdensome to maintain, and enhances community safety and quality of life by reducing frequency and severity of flooding while keeping thousands of gallons of water per rain event out of our streets, catch basins, and pumping system.”
The findings of this study are consistent with what several recent studies in other cities around the country have also documented: dollars invested in GSI generate multiple benefits like reducing localized flooding and subsidence while spurring economic activity that supports well-paying jobs and businesses.
Eness hopes this data will serve as a catalyst for development of a coordinated, data-driven strategy that places residents and contractors implementing GSI at the center of the conversation. “Building a blue-green sector that advances racial equity and economic security is the task before us. For every resident who installs green infrastructure, and for every contractor who installs it, there are countless others who are inspired by it and ready to do the same but don’t have the necessary resources, guidance or skills they need to participate,” says Eness.
