The City of New Orleans

Mayor Mitchell J. Landrieu

Pontilly Neighborhood Stormwater Network


The Pontilly Neighborhood Stormwater Network project will reduce flood risk and beautify green spaces in the Pontchartrain Park and Gentilly Woods neighborhoods through the construction of green infrastructure strategies. The project will combine improvements to the Dwyer Canal with a network of interventions along streets, in alleyways, and within vacant lots designed to slow and store stormwater. These strategies reduce the burden on the strained drainage system, reduce land subsidence, and improve water quality – all while beautifying the neighborhood.

Pontilly is a combination of two neighborhoods historically divided by the Dwyer Canal: Pontchartrain Park to the north and Gentilly Woods to the south. Pontchartrain Park is one of the first areas in New Orleans designed to provide home ownership to middle class African Americans at a time when housing developments specifically excluded people of color. This project will not only reduce flood risk for residents, but will also beautify and connect the neighborhoods.

Frequently Asked Questions

What are the benefits of the Pontilly Neighborhood Stormwater Network?

The network of infrastructure interventions that makes up the Pontilly project will primarily serve to reduce overall flood risk caused by excess stormwater runoff. Additionally, by maintaining more stable groundwater levels, the projects are intended to reduce land subsidence that damages homes, streets, and utilities. All of the improvements are designed to have multiple benefits, including health and neighborhood beautification, and some key areas will also be considered for public recreational amenities. 


Which properties are included?

The Pontilly project includes improvements to the Dwyer Canal, neighborhood streets, alleyways, NORA-owned vacant lots, and other open spaces. To see a complete map and list of properties included in the project, see below.


Does this mean you’re not building more housing?

NORA and the City will continue to seek opportunities for more housing development in Pontchartrain Park and Gentilly Woods. Neighborhood revitalization is a key goal of the Pontilly project. The improvement of stormwater management and soil conditions, plus the addition of neighborhood recreation and open space amenities, are intended to make the neighborhood even more attractive for residential development.


What about mosquitoes?

The projects are carefully designed to prevent mosquito breeding and will reduce flooding in areas where standing water currently pools in the neighborhood. The City of New Orleans has worked closely with the Mosquito and Termite Control Board on water management pilot projects over the past few years to study, monitor, and minimize mosquito impacts. This partnership will continue throughout the implementation of the Pontilly project in order to continue monitoring and ensure the most appropriate project design—including no standing water for more than 48 hours.


How is this related to the Gentilly Resilience District and the city’s resilience strategy?

The City of New Orleans participated in the federal government’s National Disaster Resilience Competition (NDRC) and proposed in its application the creation of the city’s first comprehensive resilience district in Gentilly with projects that invest in innovative and creative solutions so that people, culture, and infrastructure can thrive. New Orleans was awarded more than $141 million through NDRC, which will be leveraged with other funding sources such as the FEMA Hazard Mitigation Grant Program (HMGP) to implement elements of the Gentilly Resilience District proposal.


The Gentilly Resilience District represents a concentration of efforts across the neighborhoods of Gentilly to reduce flood risk, slow land subsidence, and encourage neighborhood revitalization. The Pontilly Neighborhood Stormwater Network is a key project within the Gentilly Resilience District, and will provide a model for how the City implements similar water management projects in the area. Additionally, the City will use funding from NDRC to add additional recreational improvements to the Dwyer Canal not covered by HMGP.  


The Gentilly Resilience District is one of the best examples of the efforts outlined in the city’s resilience strategy, Resilient New Orleans. All three of the strategy’s major visions—Adapt to Thrive, Connect to Opportunity, and Transform City Systems—are incorporated into the implementation of the district.
