Spring frost laws limit heavy trucks on many roads during the thaw, so plan around that window.
Ground Conditions Across Bay County
The county sits on the southeast lake plain. Most of the ground is clay, silty clay and clay loam, crossed by sandy beach ridges and sand channels. Drainage is poor across much of the county.
Spring snowmelt and heavy rain land on flat, slow-draining clay. Water stands in low spots, and much of the land leans on ditches and tile drains. Plan a drainage layer of drain rock or 3/4 inch crushed stone under wet areas.
Frost comes out every winter and spring. Water trapped in the soaked soil softens roadbeds, gravel drives and thin bases, so they rut. Freeze-thaw runs 42 inches under the Michigan Residential Code, a footing depth set by the building official.
Streams and ditches on the flat plain rise fast after rain and snowmelt and scour their banks. High water, storms and ice work on the Great Lakes shoreline. Riprap armors those slopes. Base, driveway and paver work runs from the spring thaw into late fall, and frozen ground stops compaction in winter.
Choosing the Right Material
Across Bay County, start with 21AA limestone for drives and pads, then add drain rock where water sits. The ground next door shifts the pick.
Arenac County shares this ground zone, that same flat former lake bed of clay and silty clay, poorly drained and crossed by sandy beach ridges. The ground is similar, so the base and drainage choices match. The likely projects differ more than the soil does.
Tuscola County sits in the Thumb and spans two zones, the southeast lake plain here plus southern moraines and till plains. Moraine ground drains better than flat clay, so a lighter drainage layer may hold.
Gladwin County is mostly sandy glacial outwash plains and sandy to loamy moraines, with wet lowlands and thin soils over limestone. Sand drains fast. Base work there needs less drainage stone than Bay County clay, but the drive can shift without a stable base.
