Clearwater takes its name from the river that slips into the Mississippi right in town, and on a still summer morning the two currents seem to meet without a sound. JW Outdoor Construction does lawn care here, among the older homes and shade trees of a small river town. Mowing, trimming and edging are done with an eye on the finished line where grass meets sidewalk. River-valley lawns grow thick in the humid heart of July, and keeping them level takes steady attention. What the work leaves behind is a yard that looks complete from the front step all the way to the curb.
