The Yellow River runs over its shoals at the edge of town, and on a spring morning that sound carries up into the Porterdale yards along the bank. K Dean Serivces LLC works those lots — mowing, string trimming, edging, and lifting the clippings and leaf litter off the walks and drive. River-bottom ground grows thick and fast once the weather warms, and it wants a regular blade rather than an occasional rescue. A clear border between lawn and woods keeps the whole place looking deliberate. Uncomplicated work, carried all the way through.
