In 2022, the City of New Rochelle undertook a citywide drainage analysis spanning six critical watersheds. This expansive project, which included assistance and input from the local community, identified and studied flood-prone locations across the City to better understand the hydrology (overland) and hydraulic (stormwater network) for each watershed.
The resulting data enabled the City to identify over 170 drainage improvement projects, which are now part of a comprehensive Stormwater Mitigation Program presented to City Council on October 10. The program encompasses a wide array of strategies both active and proactive, ranging from surface improvements and expanding system capacity, to green infrastructure and riverine improvements; and with timeframes from immediate and short-term to inclusion in the City’s 10 year capital program.
Key components include:
“These remediation strategies build a more resilient and sustainable community by improving our infrastructure, reinforcing our ability to manage stormwater effectively, and providing relief to homeowners who have been adversely impacted by flooding, especially in recent years,” said City Manager Kathleen Gill.
