While the county's Disaster Assistance Center opened on Monday to provide "consultations for property loss" and to assist in the filing of "claims, financial and food assistance" among other needs of the evacuees.

"Recovery will take time. Right now, we know many are still anxious to learn whether they lost their homes. Those who did will be seeking new housing until they are able to rebuild. Those who were evacuated but have homes to return to are still anxious about the condition of their homes as temperatures drop and the snow descends. Please know that Boulder County emergency management is working with the towns of Louisville and Superior to provide this information as quickly as possible and to allow you to return to your home as soon as it is safe to do so," the statement said.
