Records show more than $1.1 billion of the $4.7 billion in flood recovery money awarded to state and local governments remains unused five years after one of the largest natural disasters in Iowa history.
The Des Moines Register reported the amount Saturday after analyzing more than 35,000 state and federal records.
State officials have long said that recovery from Iowa's disastrous 2008 floods could take seven to 10 years, but some are concerned by the amount of money unspent or yet to be reimbursed to local governments.
Some state officials note that deadlines are nearing for thousands of projects, ranging from home buyouts to construction of flood walls. Officials say much of the delay can be attributed to reimbursements not yet showing up in paperwork as paid.
