An inundated Colorado slowly picks up the piece from record flooding from a 100-year storm, with aerial photos only hinting at the breadth of the devastation. But experts say the cleanup could offer a blessing in disguise. The state needs to fix or replace at least 200 miles of highway, about 50 bridges, and more than 2,000 destroyed homes before winter hits — the governor’s self-imposed deadline is Dec. 1, barely two months away. But perhaps this could be a change to rebuild, say Vermont officials, who were there and did that post-Hurricane Irene. The flooding might present a rare chance to thoughtfully upgrade infrastructure and urban planning, and maybe better prep for the next storm.
