Ellicott Creek drops over the rock at Glen Park in the middle of Williamsville, and the sound of it carries into the yards on either side. D.C. Landscaping & Design, Inc. tends those properties all year — mowing, trimming and crisp edging while the creek runs low and green, then plowing, shoveling and salting once the water goes to ice. Erie County gives its snow generously, and a driveway opened before the first alarm goes off is a small mercy. When the thaw comes, spring cleanup strips the sand and the leaf mat and hands the lawn back. Autumn does the reverse, and the round begins again.
