Although flooding has been ongoing for several years, a storm occurred on July 27-29 in 2011 that exposed the system-wide flooding problems.
Large thunderstorms dumped thousands of gallons of rainwater on the area during those three days. According to a report by the National Weather Service, some locations in Eaton and Ingham Counties received between six and ten inches of rain. Roadways and intersections flooded across the area. According to Randy Abbott, the Maintenance Supervisor for the Ingham County Drain Commissioner, flood waters within the Holt Shopping Center parking lot were “halfway up car doors.” Several landowners also informed the Ingham County Drain Commissioner’s staff that their basements had flooded, causing property damage.
The National Weather Service issued flash flood warnings and river flood advisories for the area because of the amount of rain expected to fall within those three days. The Sycamore Creek, which normally averages a depth of four feet, reached its flood stage of eight feet on July 28. On July 29, it crested to just below nine feet and didn’t fall back below flood stage until July 31.
The flooding that occurred on July 27-29 is shown in the pictures below for the Holt-Aurelius Roads intersection and the neighborhood northwest of the Holt-Aurelius Roads intersection.
