City officials assess flooding impacts from recent storm in Russellville Road corridor

The Bowling Green Board of Commissioners meeting on April 15, 2025, focused on the recent severe storm and its impact on local flooding, particularly in areas previously unaffected. City officials discussed the unique characteristics of the storm, which lasted four days and resulted in significant water accumulation, leading to what is termed "karst surcharge flooding." This phenomenon occurs when groundwater systems become overwhelmed, causing surface flooding as water seeks to drain through clogged cave systems.

Officials clarified that the storm did not fit the traditional definitions of a "100-year storm" or a "1% storm," emphasizing that such classifications can be misleading. Instead, they noted that the storm's return interval was estimated between 60% and 85%, indicating a higher frequency of severe weather events than previously understood.

The discussion also highlighted the need for a thorough assessment of the flooding incidents. City officials are evaluating whether existing regulations were followed and if those regulations are adequate to protect the community from future flooding. They acknowledged that some neighborhoods may require significant retrofitting to mitigate risks, but warned that the costs could exceed the value of homes in those areas.

In response to concerns about future development, officials confirmed that there are already stringent stormwater retention rules in place, particularly in the Russellville Road corridor. However, they cautioned that increasing these requirements further could hinder community growth and development.

Looking ahead, city officials committed to providing updates on their findings and potential solutions within the next few months. They aim to recommend necessary rule changes and protective measures to better safeguard neighborhoods against future flooding events.
