| March 2006 | Flash Flood | Bettendorf | $400,000 | Thunderstorms trained across the Quad City Metro area and produced rainfall rates exceeding 1 inch per 30 minutes. At 2000 CST an off duty NWS employee reported 2 feet of water over the roads in his neighborhood along the Bettendorf/Davenport city limits. By 2134 CST media and law enforcement were reporting water 4 inches deep was flowing into the Davenport Police Station on Harrision street. Numerous streets were closed due to high water; Harrision by the police station and River Drive in several spots. The media was reporting sinkholes developing on some streets in Davenport with some residences flooded. Although unknown at the time, the Federal Building in downtown Davenport had its basement partially flooded. Near the Oscar Mayer/Kraft plant, 2-3 feet of water was on second street while River Drive and 3rd street by the Quad City Times Newspaper had thigh deep water. The flash flooding in Davenport was exacerbated from winter debris blocking storm drains and therefore preventing or restricting the amount of water getting into storm sewers.By 2230 CST, spotters and the media were reporting that flooding in downtown Davenport was beginning to recede. It is unknown how many buildings received water inside them but it is probably safe to say it was a few dozen. The flooding of the police station was caused by a police car blocking a storm sewer drain. A city engineer with Davenport concluded that this level of flooding was typical for a 15 to 20 year event.KMLI ASOS reported 1.78 inches of rain for 12 March 2006 of which 1.66 inches fell during the 1800-2400 CST time period. At the same time, the KDVN ASOS reported 1.05 inches of rain for 12 March 2006. The heaviest rain occurred during the 1900-2300 CST time period in a narrow band in between the two ASOS sites. The highest know rainfall amount occurred in central Davenport where 3.50 inches of rain fell. The closeness of the heavy rainband to the KDVN 88D resulted in a severe underestimation of the rainfall. Rainfall estimates from the distant KILX and KLOT 88D sites indicate 3-4 inches of rain fell. |
