Shrewsbury yards: grade changes, ledge and the lake
A lot of Shrewsbury sits on rolling ground that drops toward Lake Quinsigamond on the west side of town. Around Edgemere and the streets off Route 20 you see houses set into slopes, with a walk-out basement on one side and a steep run of lawn on the other. That kind of lot is where a patio needs a real base and, often, a short retaining wall to hold the level area in place.
Like most of Worcester County, the soil here is glacial till: a dense mix of sand, silt and stones that does not drain quickly. Dig a footing and you can hit boulders or ledge. We plan for that before we price a job, because an excavation that runs into rock changes the work, and you should hear about it at the estimate, not halfway through.
Homes near the water deal with something else: runoff. Roof water and driveway water that sheet across the yard can carry soil toward the shoreline. A dry well or a properly pitched patio keeps that water on your property and lets it soak in slowly.
