Phase 3 Drainage Project - Outfalls & Basin
The City has initiated the third phase of a project to improve storm water and tidal drainage across the island. This project is intended to make significant drainage improvements to the 30th, 36th and 41st Avenue outfalls which will improve conditions on the amount of standing water events experienced by residents and property owners. The project began in 2017 when City Council tasked the Planning Commission with developing a strategy to address drainage problems. As part of the project, smaller but impactful drainage improvement projects along the basin will also be addressed. These are located at Sparrow Drive, Forest Trail, Cross Lane, 32nd Avenue and 41st Avenue.
During the regular Public Works Committee meeting held on August 5, 2020, Thomas & Hutton gave a comprehensive update on the status of the Phase 3 Drainage project, the small but high impact projects located at Sparrow Drive, Forest Trail, Cross Lane, 32nd Avenue and 41st Avenue and the Waterway Boulevard path elevation project.
