ON-GOING/RECENTLY COMPLETED SAMPLE PROJECTS:

Bartlett Road Sanitary Sewer Project Village of South Barrington, Illinois: The Village of South Barrington is a bedroom community of approximately 4,500 people located north of the Northwest Tollway, outside Chicago. The Village provided no water or sewer utility services and decided to implement a sanitary sewer plan for its commercially zoned property. The Village had to obtain Facility Plan approval from the Northeastern Illinois Planning Commission and Illinois EPA for approximately 600 acres of land.

Carroll Engineering & Associates was a primary participant in the preliminary work, and was contracted to perform the final design, preparation of construction documents, permitting and easement work, bidding assistance, and construction administration. The length of the project was 26,000 feet with a bid price of $3.06 million. The final discharge point for the sewer is a Metropolitan Water Reclamation District (Chicago) trunk sewer in Streamwood, Illinois. Approvals for the project were required from MWRD, Village of Streamwood, Cook County Highway Dept., Cook County Forest Preserve District, Tollway Authority, Illinois Department of Transportion, and several private easements.

Combined Sewer Overflow Permit Compliance Program - City of Elgin, Illinois: The City of Elgin's central area had originally been constructed with combined sewers serving both storm water runoff and sanitary waste flows. Due to new federal standards the City was required to perform detailed system hydraulic analysis to determine system capacity, prepare an operations plan that includes routine system maintenance, and maintain complete records of system inventory and maintenance operations.

The work performed by Carroll Engineering includes updating the hydraulic model with system improvements, assistance in permit compliance activities, system inspections and mapping. The mapping is computerized using a base map prepared by the City. System inspection and inventory reporting are done using a computerized database system.

Kishwaukee Riverfront Bike Path

The Boone County Conservation District in coorperation with the Belvidere Riverfront Committee obtained IDNR grant funds to extend an existing rierfront path in Belvidere Park, downtown Belvidere, into Spencer Conservation Area on the west side of town, which is Conservation District Property. During Phase I planning CE&A performed oute alignment and costing studies for the Riverfront Committee that were used to select the primary path location and identify right of way and environmental issues. Due to multiple local agency involvement, Phase II design was split between two firms.


Carroll Engineering & Associates designed the portion of the path in Spencer Conservation Area. Total length of this section was 5,853 ft. CE&A prepared design surveys, contract bidding documents and also performed construction administration duties. Carroll Engineering developed a site design which integrates the natural features and beauty of the Spencer Conservation Area with pedestrian friendly pathways. The plan provides enhanced accessibility and views of the pond, prairie and woods, and improved convenience and utility for path patrons.

Land Development:
Land development includes the extension of sewer and water services to and throughout the properties. Carroll Engineering has recently completed or is working on the design of several subdivisions, including:

Leeland Place (Rockford, IL) - 20-acre residential
Sandy Hollow Plaza (Rockford) - 8-acre commercial
Buckley Commercial Center (Rockford) - 16-acre office/research
Market Square (Cherry Valley, IL) - 15-acre commercial

Maplewood Drainage Project - Rockford,Illinois:
The Maplewood area was originally developed in the County as a rural subdivision. Due to encroaching development from the City upstream of this area, it has begun to experience severe routine flooding. The project consists of determining basin wide runoff flows, hydraulic analysis of the capacity of existing ditches and culverts, design and construction administration of improvements to provide a minimum 25-year capacity for all sewers and minor structures and 100-year capacity for major structures, including significant easement acquisition.
