NEW CITY, NY — Rockland County Executive Ed Day announced on Nov. 2 the appointment of Joshua Nathanson as the new Executive Director of the Rockland County Drainage Agency.

Mr. Nathanson assumed his new role at the end of August, with an annual salary of $151,750. He replaces former Executive Director Vince Altieri, who passed away in 2025.

He joined the agency following three years of service as a Principal Assistant County Attorney within the Rockland County Attorney’s Office, where he served as legal advisor to the county and Planning Department. His work included reviewing and analyzing State Environmental Quality Review Act (SEQRA) determinations and conducting environmental reviews for open space purchases, as well as county-owned and constructed facilities. Prior to that, Mr. Nathanson spent a year as an Assistant District Attorney within the Rockland County District Attorney’s Office.

The Rockland County Drainage Agency was established in 1975 by the Rockland County Stream Control Act (Chapter 846 of the Laws of 1975) to manage and protect floodplains while preserving natural water flow. It regulates development, construction and maintenance along 14 designated county-protected streams totaling an estimated 78 miles. Any development within 100 feet of the 100-year floodplain requires a permit from the county.

“Following Hurricane Floyd, it took nearly a decade to fully repair the extensive damage that was done,” said Rockland County Executive Ed Day. “However, thanks to increased staffing, more frequent inspections and sustained diligence, the Drainage Agency has helped ensure that flooding has remained minimal.”
