Between the mesas and the interstate, the office parks on the Pleasant View bench sit dark and quiet at midnight, which is precisely when a storm gets handled. Environmental Designs runs the night side of winter out there — pushing lots, opening doorways, stacking the piles where they will not cost anyone a sightline — and turns to the mowing rounds, the string-trimmed fence lines and the spring cleanups once the ground softens. The measure of a good night is that nobody at seven in the morning gives it a thought. Summer's measure is simpler: straight lines in the turf and clean beds beside them. Golden, Lakewood, Applewood and Arvada.
