Mahoney Creek Tributary
The City of Batavia is working on restoring stream quality throughout the City. This webpage will focus on the project to detain stormwater runoff upstream of the Mahoney Creek Tributary.
As part of the City of Batavia’s efforts to alleviate repeated drainage concerns and flash flooding along the Mahoney Creek Tributary and Mahoney Creek mainstream the City is exploring options to detain excess runoff upstream on a City owned parcel and potentially in an upstream existing drainage easement. The upstream drainage area in question is generally bound by Wilson Street to the north, Woodland Hills Road to the west, Pine Street to the south and Fermi National Laboratory to the east where the runoff drains from the east under Kirk Road thru the City owned property to the Fox River via Mahoney Creek.
The City completed a preliminary investigation and analysis on different scenarios and options for additional detention capacity upstream of the Woodland Hills neighborhood in the fall of 2018. The final report is being used to anticipate the scope of work for Phase 2 final engineering plans. It should be noted that the 2018 study contemplated expansion of the existing stormwater basin east of Kirk Road as the primary option. Since the time of the initial study the City has finalized its acquisition of parcels west of Kirk Road for the purpose of stormwater management. Through the final design process the City desires to evaluate various different options/alternates to retain runoff on the parcels west of Kirk via a retaining wall, landscaping berm or some other type of structure to be constructed along the westernmost property line. Expansion of the existing stormwater basin will be included as alternate work within the final bid package, depending on the engineer’s estimate of probable costs.
