ST. CHARLES – The city continues to move ahead with a project to address flooding problems along the 7th Avenue Creek.
As Ken Jay, manager of the St. Charles Public Works Engineering Division told aldermen in a memo, the city has been strategically procuring properties along 7th Avenue Creek for the purposes of mitigating flooding issues and for future capital improvements.
That includes a house at 1734 Riverside Ave., which the city acquired in 2018 and is in the floodway of 7th Avenue Creek. The city now plans to demolish the house.
Yorkville-based Kendall Excavating submitted the lowest bid $24,350 – to raze the house. Aldermen will vote on the contract in the coming weeks.
"City staff will be subdividing the lot, which will allow the city to sell a buildable lot and recoup some of the acquisition and demolition fees," Jay said. "The parcel that contains the floodway and floodplain will remain under city ownership."
In December, alderman approved a contract with HR Green, Inc. for design engineering related to phase one of the 7th Avenue Creek Project. A significant rain event in September 2008 impacted much of the area adjacent to the 7th Avenue Creek and the 7th Avenue Creek Tributary, resulting in extensive property damage, street and yard flooding and erosion along the stream banks, according to city officials.
After the rainfall event, the city noted that the flooding limits far exceeded those illustrated on the current flood insurance rate maps published by the Federal Emergency Management Agency.
Aldermen last year also approved acceptance of a $1.2 million Illinois Environmental Protection Agency grant for the first phase of the 7th Avenue Creek Project, which spans from Washington Avenue to South 10th Avenue. Phase 1 will include property acquisition, removing a portion of South 9th Avenue and reestablishing a meandering creek with a buffer of native plantings.
The plan also includes creating a park-like setting with a walking path, the replacement of storm culverts underneath Illinois Avenue, Indiana Avenue and South Avenue, and lowering of the 100-year floodplain within the project limits. The project is expected to cost $5.8 million.
The contract with HR Green, Inc. calls for design engineering not to exceed $369,576. Staff has proposed approving $95,025 of the contract at this time, with the remaining funds being separately budgeted over the next two years.
