A hybrid natural and engineered water system in New Orleans’ signature public park
reduces neighborhood stormwater flooding.
This resilient planning initiative aims to improve City Park’s extensive network of lakes with an emphasis on water quality and physical enhancements. Initial steps included an analysis of soils, groundwater, and water systems within the park. Coupled with potential flood hazard reduction in the adjacent neighborhoods, this research led to the development of two design proposals to be implemented using FEMA Hazard Mitigation Grant Project funding.
The plan includes connecting low lying areas with bioswales to store, infiltrate and direct rainwater to one of the larger lakes. Reshaping and stabilizing the lake shoreline increases storage capacity, improves water quality and reduces loads on the municipal drainage system.
