Bishop Avenue Erosion Control

The Peoria Park District selected IEI to help facilitate a $1.2M improvement project to mitigate erosion issues at Grand View Park. The project improvement included replacing the storm pipes and inlets in the Grandview Drive pavement and installing storm pipes and structures to connect the inlets to the storm sewer system under Galena Road. The two storm sewer inlets at Grandview Drive release directly into the gully, which escalated the erosion. The ground east of Grandview Drive collapsed into the gully and was encroaching on the pavement. As a result, the erosion was depositing large amounts of sediment onto Galena Road (Illinois Route 29)

The District anticipated a 230 ft vertical drop, the full length of the gully (approximately 650 feet) in order to re-grade and stabilize the structure, a replacement of the pavement and structures at Galena Road’s Right of Way (ROW), as well as vegetative, environmental best practice management plan.

As the Prime Consultant on this project, IEI provided preliminary construction documents to analyze and mitigate the erosion located east of the projected intersection of Bishop Avenue and Grandview Drive. IEI, then, provided inspection services through the construction period to assure quality due to the scope of work and severity of the erosion located east of the projected intersection of Bishop Avenue and Grandview Drive. To conclude the project, IEI provided final construction documents, SWPPP and IEPA support documents, MOT, estimate of quantities and cost estimates, technical specifications, drainage calculations for storm pipes and detention basins, construction administration and construction observation.
