Client: Brook Forest Homeowner's Association
Location: Oak Brook, IL
Project Scope: Permitting Assistance, Plant Establishment & Maintenance Planning, Construction Observation, Vegetation Monitoring/Reporting
|The Brook Forest Shoreline Stabilization site is located along Ginger Creek between Midwest Road and Regent Drive, in Oak Brook, IL. The project encompasses two pond shorelines and two stretches of Ginger Creek shoreline. The ponds are formed by two existing in-stream dams. Bank erosion within the ponds and channel segments has caused severe undercutting, due to water level fluctuations, erosive velocities, Canada Goose populations, ice sheer, and inappropriate vegetation. This portion of Ginger Creek contains regulatory floodplain and floodway areas that required permitting through the Village of Oak Brook, a full-waiver community that conducts required County & Army Corps of Engineers permit review in-house.|
ecology worked with the design engineer, Engineering Resource Associates (ERA), to simplify the proposed design of soil-lifts and vegetated rock toe, ultimately resulting in a re-design that stabilized approximately of 3,000 linear feet of shoreline, using simple grading techniques, native vegetation and reduced necessary bioengineering measures to include coir fiber rolls and vegetated rock toe within only the higher velocity area downstream of the second dam. ecology also joined with ERA and the Brookforest Homeowners Association (HOA) in discussions with DuPage County in order to “fast-track” the permitting process, a process that achieved permit approval without the requirement of an FEQ model. ecology’s involvement in the planning and permitting stages brought significant value to the project, saving the Brookforest HOA approximately $300,000.00 in construction costs and $50,000.00 in design fees.
