Country Creek Stabilization

Village of Bartlett

OBJECTIVE

The Village of Bartlett needed a comprehensive streambank assessment and final engineering design for West Branch DuPage River Tributary No. 2. The creek runs through an existing easement behind 36 residential properties, making resident communication a key component of the project’s success.

PROJECT DESCRIPTION

HLR conducted a Phase I streambank assessment, identifying stabilization alternatives and funding opportunities. The assessment included a site visit, historic aerial review, topographic survey analysis, and stream condition evaluation. Three main alternatives were developed, incorporating stabilization methods such as gabions, sheet piles, bypass stream piping, culvert extensions, and stream diversions. Each alternative was assessed for cost, feasibility, environmental impact, and utility conflicts.

HLR presented the alternatives at a community open house with Village staff and in a coordination meeting with the Army Corps of Engineers Chicago District. Additionally, grant opportunities, including the IEPA Green Infrastructure Grant, IEPA Section 319(h) Grant, and the DuPage Water Quality Improvement Program Grant, were evaluated for funding potential.

Now in Phase II, HLR is finalizing design and permitting for the selected alternative. This includes detailed land surveying and plat preparation for easements on the 36 adjacent properties. The permitting process involves multiple agencies, including the Army Corps of Engineers, IDNR, DuPage County, and the IEPA. Hydraulic modeling using HEC-RAS and compensatory storage calculations will support regulatory compliance. HLR will continue assisting the Village with resident outreach, utility coordination, and grant applications, including submitting an IEPA Section 319(h) grant.
