Iowa Congressman Tom Latham, Friday, announced that some Pottawattamie County properties ravaged by Missouri River flooding last summer will receive help in the form of federal disaster grants. The FEMA hazard mitigation grants will be used to buy out 32 residential properties and one commercial property that were damaged beyond repair. Under the grant structure, the federal government will cover 75 percent of the costs, or a total of about $4.77 million, while the state government will cover the remaining costs.
