Project Description

Cedarmere-Chelsea Pods 7-22-11 031As part of its effort to restore and or improve the quality of selected, scenic, water resources and habitats in the County, the Nassau County Department of Public Works retained D&B to conduct a study of Chelsea House Pond in the Muttontown Preserve and Cedarmere Pond in Roslyn Harbor.
