The postal service has had to adjust its operations in response to the flooding in Colorado:
USPS is closely monitoring conditions in the Boulder Colorado area. Due to widespread flooding and road closures, delivery has been impacted. USPS has relocated postal services for a number of addresses in the areas of Jamestown, Coal Creek Crescent, Lyons, Allenspark, and Drake, along with Glen Haven, Estes Park, Bellvue, Masonville, Milliken and Orchard.
While delivery may be impacted in these areas due to road closures, impassable roads, and inaccessibility of mailboxes, USPS will make every attempt to deliver to all addresses.
