The City of West Chicago’s annual water improvements program recommended replacement of the existing infrastructure under Illinois Route 59 from Washington Street through Hillview Avenue.  The existing main was constructed prior to expansion of Illinois Route 59 to a five lane roadway, therefore much of the underground utilities were located below the existing pavement.  

Trotter and Associates completed a topographic survey of the project limits.  Underground utilities were located using field data collection, coordination with the City of West Chicago staff, and the use of previous improvement plans. 

During the design and permitting phase Trotter and Associates prepared a set of final engineering plans detailing not only the improvements to be constructed, but the anticipated phasing of construction to minimize service interruption and roadway closures.  The project was permitted through the Illinois Environmental Protection Agency, Illinois Department of Transportation and the DuPage County Division of Transportation.  Additional coordination was required with residents, business owners, and IDOT for permanent and temporary easement dedications.  Trotter and Associates was responsible for document preparation including plats and agreements.

This project was constructed in 2005 and upon completion the project provided approximately 1,900 lineal feet of new ten-inch diameter water main.  This was completed through the use of three subsurface crossings under Illinois Route 59.
