Slopes are mainly 2 to 12 percent and range from 0 to about 60 percent. These are the Barry , Dryden , Gilford , Locke , Mussey , Oakville , and Spinks soils. The moderately well drained Dryden soils, the somewhat poorly drained Locke soils, and the poorly or very poorly drained Barry soils form a common drainage sequence with the Lapeer soils. The sandy Oakville and Spinks soils are on slightly higher parts of some moraines. Small areas of the sandy somewhat poorly drained Wasepi soils, poorly drained Gilford soils, and loamy poorly drained Mussey soils are in drainageways in some of the moraines.
Surface runoff ranges from slow to rapid, depending upon slope.
Permeability is moderate. Eighty percent or more of the Lapeer soils on slopes of less than 12 percent are under cultivation. The principal crops are corn, small grains, beans, and hay. A large part of the steeper slopes, and a small part of the gentler slopes are in permanent pasture or in woodland. The native vegetation is forest of oaks, shagbark hickory, and sugar maple.
