Before the first employee turns into a lot off Valmont, the pavement is already cleared and the entry walks are down to bare concrete. Boulder Commercial Maintenance handles grounds for businesses and properties, which means plow routes that begin in the dark and finish before opening, sidewalks shoveled end to end, and de-icer laid at doorways and curb ramps. In the green months the same properties get mowing on a set schedule, string trimming around bollards and sign bases, edging along the curb lines, and cleanups that keep beds and walkways clear. The landscape strips between parking rows take the worst of the high-altitude sun, so those get the extra attention they ask for. The measure of the job is that nobody notices it — the lot is open, the walk is dry, the grass is cut.
