Village of Hewlett Harbor Stormwater Infrastructure Resiliency

After suffering extensive damage during Superstorm Sandy, the Village of Hewlett Harbor commissioned a drainage study to evaluate the existing stormwater drainage system and assess the periodic flooding conditions at five locations. After the study’s completion, D&B was retained to evaluate the study and its conceptual alternatives; recommend specific mitigation measures; and help the Village implement these measures through application development, engineering design, bid preparation, construction observation and administration of the various improvements.

D&B undertook extensive hydraulic modeling to determine the most appropriate improvements that should be implemented and participated in an outreach program with existing public and private utilities to coordinate their capital improvement programs’ timetable with the project schedule. Once completed, the project will mitigate flooding by replacing undersized drainage lines and installing infiltration/detention facilities, flood tide gates, a water quality system, and green infrastructure.
