In June 2008 Cedar Rapids was engulfed by flood waters from the Cedar River, causing wide-spread devastation. Six weeks after the flood the first open houses were held to develop the flood management strategy. This planning began the process of defining the boundaries of neighborhood reinvestment and redevelopment. More than 2,600 community members participated in the flood management alternatives. The final series of public meetings resulted in the city council approving a flood management strategy in November 2008, just five months after the flood.
