Governor Terry Branstad says storms that brought flooding to Iowa since May 19 caused an estimated $22 million in damage that is eligible for federal public assistance.
The governor has sent a letter to President Barack Obama requesting a presidential disaster declaration that would include 47 of Iowa's counties.
The storms brought damaging wind, tornadoes, heavy rain and thunderstorms causing flash flooding.
The request includes counties scattered throughout the state including most of northwest Iowa, but not Woodbury County.
Public assistance funds may be used to rebuild damaged roads, bridges, culverts and other public facilities, or to cover emergency work costs.
