Water Supply

Since 1991, several partners at Young/Sommer have had the unique experience of representing the towns in the New York City watershed in the contentious negotiations and litigation surrounding New York City’s efforts to avoid the requirement to filter its drinking water supply. The firm’s partners helped negotiate the historic 1997 New York City Watershed Memorandum of Agreement and have continued to represent communities in the watershed in subsequent negotiations associated with updates to that agreement. The firm also regularly assists clients with permitting and compliance issues associated with New York City’s watershed regulations. In addition, over the years, the firm has helped municipal and private clients comply with federal and state drinking water rules.


Young/Sommer has extensive experience at the federal, state, and local levels with both freshwater and tidal wetlands issues and can help devise innovative strategies to mitigate wetlands impacts when development in a wetland cannot be avoided. In addition to traditional development issues, the firm has experience in contesting the designation of wetlands and obtaining permits for the renewal and expansion of marina and related facilities in New York tidal wetlands.
