Kane County completes major stabilization work on Geneva Creek; monitoring and maintenance to continue

Kane County officials on Wednesday described the completion of a months-long stream‑stabilization project at Geneva Creek that runs through the south end of the Kane County Government Center campus and into the Fox River. Rob Linke, a civil engineer who presented the project to the county’s Administration Committee, said contractors and volunteers stabilized roughly 1,300 feet of stream, repaired severely eroded banks and restored access to the Geneva Grotto area.

The work drew on multiple funding sources. Linke said the project used $250,000 from a Grand Victoria Riverboat grant, $200,000 from Kane County’s wetland fee‑in‑lieu fund and a $50,000 pledge from the Kane County Forest Preserve District. He said the county pursued a design‑build approach, contracted NCAP after a late‑2013 request for proposals produced two responses, and that permitting delays — including an Army Corps archaeological survey request — pushed construction into spring. "Many hands make light work," Linke said, acknowledging volunteer leaders and residents who cleared invasive species and hauled brush.

Why it matters: committee members and volunteers said the restored corridor returns a neglected but locally valued natural area to safer condition, reduces future erosion risk and improves public access near county facilities. The project also used county mitigation funds intended to compensate for wetland impacts elsewhere, applying them to on‑site restoration.

Details: Linke said an assessment prepared in 2023 mapped most of the creek’s banks as severely or badly eroded, with preliminary cost estimates ranging from about $150,000–$200,000 for minimal work to roughly $700,000 to stabilize the entire corridor. The combined budget and the design‑build approach allowed the team to maximize construction work in one contract. Site clearing and volunteer work began more than a year before construction; formal construction began in April and included rock toe bank stabilization, rock riffle grade controls and glacial boulders as top‑layer features to blend with the corridor’s historic character. Linke credited NCAP as the prime contractor and named Schultz Excavating as a subcontractor that handled heavy equipment work.

Volunteers and partners: Bob McQuillan, a Batavia resident who represents the Geneva Grotto organization, thanked the Forest Preserve District, county building management and volunteer crews. "It is, amazing, totally amazing what was, able to be done down there," McQuillan said during public comment. Linke and county staff singled out the Forest Preserve District’s volunteer natural area program, which supported repeated volunteer workdays to remove invasive honeysuckle, buckthorn and other overgrowth prior to contractor work.

Next steps and constraints: the contractor’s contract includes monitoring and maintenance obligations for the disturbed and restored areas for the next three years; county staff said herbicide control, seeding and ongoing invasive species management will continue. Committee members asked for a short list of possible follow‑on projects — for example, restoring the Walter Stevens memorial fern garden or rebuilding one or more footbridges — and Linke agreed to prepare options and cost estimates for those "druthers" for later committee consideration. County staff emphasized the project required and received federal and state permits and noted that timing was affected by permitting windows and storm events.

Meeting context: the presentation lasted the bulk of the committee’s morning agenda item, and the committee scheduled an informational site tour of the stabilized corridor after the meeting. Committee members and county staff stressed the tour would be informational only and that no county business would be conducted while on site.

Ending: county staff said drone imagery and geo‑referenced video captured before, during and after the work will be shared so the public can compare conditions; staff also said they will continue coordinating with the Forest Preserve District on any restoration projects that fall on preserve property.
