The effects of the Aug. 10 derecho, a violent thunderstorm system that struck Iowa with 100-mph winds, are still being felt as rebuilding has begun.
One of the cities hardest hit by the storm was Cedar Rapids, where it is estimated that more than 800 buildings experienced partial collapse of the roof, walls, ceiling or floors. Among the damaged buildings was the city-owned ice arena, ImOn Ice, which had half its roof torn off, as well as more than 20 school buildings in the city.
