ERA provided Phase I, II and III engineering services for the replacement of the water main along Oak Avenue, Illinois Road and Western Avenue in the Village of Northbrook. Work also included complete reconstruction of approximately 3,100 feet of Western Avenue.  Approximately 12,400 feet of new water main replaced the existing cast iron mains that had an extensive break history. The project corridor was lined with primarily residential properties and was also home to Wescott School on Western Avenue.  In addition to coordination with residents, design and construction was discussed with District 30 staff in an effort to minimize impacts to the school’s schedule and operations. ERA completed detailed construction staging plans and value engineering.
