Whitestown, for example, requires Zoning Review Approval for accessory structures, keeps them out of easements, and refers regulated drainage easement questions to the Boone County Surveyor's office1.

For Lebanon, Thorntown, Jamestown, Advance and unincorporated areas, we haven't published town-specific guidance yet. Contact your city or town hall, or the county planning office, to confirm what a patio or pergola needs.

Ground conditions in Boone County

By mapped acreage, Boone County's USDA soil survey is led by Crosby (about 28%) and Treaty (about 25%), followed by Miami, Fincastle and Cyclone2.

Treaty is mapped mostly as silty clay loam on nearly flat 0–1% slopes, and Crosby is somewhat poorly drained4. On flat, slow-draining ground, a patio needs enough slope and a clear path for water, or it will hold puddles and heave.

Indiana's residential code lists a 30-inch frost depth for Boone County, which applies to footings for pergolas, seat walls, fireplaces and outdoor kitchens3.

Who handles drainage easements in Boone County?

Whitestown's application says regulated drainage easements are handled by the Boone County Surveyor's office. Check with your town for local easements.

What soil is common in Boone County?

Crosby and Treaty make up more than half the mapped acreage in the USDA survey. Both are slow to drain, so base depth and drainage are key.
