The Bridges & Dams and Subdivision & Site Plan Section monitors the condition of the County’s 176 bridges and 327 culverts. They also design replacement bridges and monitor construction of new bridges and culverts. The Bridges and Dams section also is responsible for five county owned dams and flood control projects.
The Subdivision & Site Plan Section works in conjunction with the County Office of Planning Division of Development Review  to review all subdivision and site plans submitted for approval. The basic guidelines for review are outlined in the Middlesex County Land Subdivision and Site Plan Resolution. The engineering review primarily covers two aspects, drainage and traffic. The section utilizes the special knowledge and experience of the other sections of the office.
