About Columbia Property Maintenance, a division of Columbia Sweeping Service, Inc.

Sacagawea State Park marks the spot where the Snake River gives itself up to the Columbia, a broad confluence that Lewis and Clark once camped beside and that still fogs over thick on the coldest winter mornings. That river fog drifts into Pasco proper and lingers until midday, freezing hard on any surface it touches overnight. Columbia Property Maintenance, a division of Columbia Sweeping Service, Inc., plows parking areas and clears walkways across town, working through the fog to break up the ice before the day's foot traffic starts. It's a strange kind of winter — rarely deep snow, but the river's own breath turning every flat surface treacherous — and clearing it is less about shoveling drifts than about staying ahead of the glaze.
