NEW ORLEANS — Flooding is one of the most urgent challenges New Orleans faces. The New Orleans Office of Resilience and Sustainability (ORS), in partnership with The Water Collaborative and ISeeChange, will host a community meeting to share results from the recently completed Hydrologic and Hydraulic (H&H) study for the Lakeview, Lakeshore, and Lake Vista neighborhoods.
An H&H study uses computer models to show how rainfall moves through streets, pipes, and green spaces during storms. The results highlight where flooding is most likely to occur and what drainage solutions—such as green infrastructure and traditional drainage systems—may provide the greatest benefit.
At this meeting, ORS will:
- Present the study findings in plain language.
- Explain how results can inform both near-term and long-term drainage improvements.
- Provide an opportunity for residents to share feedback and priorities.
WHAT: Community presentation of Lakeview H&H drainage study results
WHEN: Wednesday, Oct. 22 @ 6pm – 7:30pm
WHERE: Edward Hynes Charter School – Lakeview, Library
900 Harrison Ave.
This effort supports the City’s Climate Action Plan, which calls for completing 21 green infrastructure projects by 2035 to manage 92 million gallons of stormwater. As of December 2024, 6 projects have already been completed, diverting 12 million gallons. These include the Pontilly Stormwater Lots Network, St. Roch Drainage Project, Oak Park Drainage Improvements, and Hagan Lafitte. Two additional projects are currently in construction, which together will divert another 23 million gallons, bringing the total to 35 million gallons of stormwater managed once completed.
Green infrastructure is proven to absorb water where it falls. Types of green infrastructure include rain gardens, grass plantings at street corners, bioswales and stormwater parks, but not all solutions are green. A combination of “grey” features in combination with green infrastructure can provide greater flood protection. These types of features include underground tubes that are used to store rainwater and permeable pavement and gutters – all of which allow rain to soak into the ground, reducing runoff and easing pressure on drainage systems.
