Thirty-two square miles west of the city, where the soil changes from one end of a property to the other.
Request a ConsultationScio is the township where soil behaviour catches people out. It sits on glacial outwash plains and medium-textured end moraines, and the practical consequence is written into the Honey Creek watershed plan: sandy soils along the drainage ways let water through quickly, while clay-dominated areas drain slowly, and former wetland areas barely drain at all. You can find all three on one property.
That's why the same planting scheme can thrive on one side of a Scio garden and drown on the other. Before a plan gets drawn here, it's worth knowing which ground you're standing on. Honey Creek itself runs twenty-six miles of branching channel with no dams and a steep thirty-feet-per-mile gradient, which makes it unusually flashy. It rises fast after rain and drops fast afterward.
The township has been protecting land seriously for two decades, with a preservation millage passed in 2004 and renewed in 2013, and conservation easements across farms and woodlands from Frey Preserves at the Honey Creek headwaters to the Kidder-McKeachie Scio Woods Preserve, one of the largest remaining beech forests standing near Ann Arbor. It's a good place to build a garden that belongs to its setting.
Outwash sand drains fast, clay drains slowly, and old wetland ground holds water. Knowing which is where is most of the work.
Twenty-six miles of channel, no dams, thirty feet of fall per mile. Runoff arrives fast, so slowing water on site is worth real money.
The Honey Creek plan counts roughly 6,700 private septic systems outside the sewer service area. Drain fields shape where planting can go.
Beech and oak-hickory woods, old hayfields and hedgerows. Gardens here look best when they read as part of that, not imposed on it.
Every project is designed for the property it sits on. These are the services Scio Township clients ask for most.
Common Questions
Because Scio's soils genuinely change over short distances. The watershed plan describes sandy soils along drainage ways with rapid infiltration alongside clay-dominated areas with slow permeability, and slow-infiltration zones where wetlands used to be. Two beds thirty feet apart can need completely different plants.
It's a fair question to ask, and it's a matter for the township and EGLE rather than for us. The Gelman plume affects parts of Scio, and it was added to the EPA's Superfund National Priorities List in March 2026. If you irrigate from a private well, check your status with the township directly. Municipal water in Scio is purchased from the City of Ann Arbor.
Deep-rooted native perennials and prairie species handle Washtenaw clay far better than most ornamentals, because their roots open the soil over time instead of sitting in a hole of amended dirt surrounded by clay. That's usually the honest answer rather than trying to change the soil.
Yes, and it's often the right call given how quickly Honey Creek responds to rainfall. Aaron is a certified Master Rain Gardener with sixty-six county-inspected rain gardens built in Washtenaw County.
