For now, Bach said, the news of the destruction would make it very difficult for the city about 60 miles south of Denver.
"This is going to be a tough evening, but we're going to get through it," Bach said. "This community is going to surround them with love and encouragement ... We will move forward as a community."
More than 30,000 people frantically packed up belongings Tuesday night as the flames swept through their neighborhoods. While there's no indication yet the blaze claimed any lives, fire officials said they would search each home looking for possible remains.
The Colorado Bureau of Investigation said two people have been arrested in connection with a burglary at an evacuated home. Belinda Yates and Shane Garrett were being held on charges including second-degree burglary and possession of methamphetamine.
Community officials were planning to begin the process of notifying residents Thursday that their homes were destroyed. For many residents, the official notification was a formality.
Residents recognize their street on aerial pictures and carefully scrutinize the images to determine the damage. Photos and video from The Associated Press and the Denver Post showed widespread damage.
