After 17 years, Crescent Beach has officially reopened! 🏖️
To help remediate surface water contamination and allow community members to return to the beach, H2M partnered with the City of Glen Cove to develop strategies and designs to address the contamination issues at nearby sites. This resulted in a multi-year program that included the installation of two Helix filter systems, grading and landscaping for a rain garden, and the replacement of a clogged box culvert to promote higher tidal exchange with wetlands near the beach.
With these improvements in place, along with sampling data from the past three years, the Nassau County Department of Health recently granted conditional approval for the City to reopen the beach. While safeguards will remain in place, H2M and the City are thrilled for residents to regain access to the water at Crescent Beach for the first time since 2009!
