COLORADO SPRINGS, Colo. (CBS4) – Scorched hillsides left by last summer’s Waldo Canyon Fire are a big concern. The worry is that spring showers could cause intense flash flooding in that area of Colorado Springs.

The fire destroyed 346 homes and became Colorado’s most destructive wildfire. Before it burned, the hillsides were covered with vegetation and soaked up water. Now the area is described as a parking lot.

Some worry the water that runs through the burn area will pick up debris and that could damage homes, bridges, culverts and streets.

Environmental groups have started to replant vegetation that was destroyed.
