Class A roadstone is the base course most drives and pads here start from. It is crushed limestone with the fines left in, so it binds and compacts under a truck or a tractor.

Materials for Brooklyn Projects

Coarse stone carries the slope, swale and bank work around Brooklyn. Poweshiek County ground cuts deep in places, and heavy rain moves a lot of soil off a bare bank.

Big angular rock slows that water down and holds the ground behind it.

At the top of the size range, riprap is the answer for stream bank armoring, culvert outlets, pond edges and slope protection against spring runoff.

Use Riprap where moving water meets bare soil.

Below that sits clean rock, washed and open graded so water moves straight through it. It goes into subdrains, drainage tile backfill, pipe bedding and the backfill behind a retaining wall.

Clean Rock comes in 1 inch clean and 1 1/2 inch clean sizes.

For a driveway or lane that has thinned out, driveway rock tops an existing compacted roadstone base. Driveway Gravel keeps a working surface under tires without the coarse open texture of clean stone.

On the finer end, limestone screenings bed pavers and flagstone, fill joints and dress a compacted base. Limestone Screenings are the 3/8 inch minus grade Iowa yards stock for that work.

Where you want a soft surface rather than a structural one, Top Soil covers lawn repair, grading and bed prep. Iowa yards call screened topsoil black dirt after the dark prairie soils the state is known for.

Ground and Conditions in Brooklyn

Across the Southern Iowa Drift Plain, old till sits under a windblown loess mantle. Below that is a thick grey clay paleosol that water will not move through, and farmers call working in it gumbo.

Steeply rolling ground drains at the surface, but the clay subsoil does not take water. It perches, runs off, and leaves drives soft at the bottom of a grade.

Spring rain on saturated clay is the worst of it.

That is why clean rock and riprap matter on slopes and outlets here. This is Iowa's most eroded landscape: streams cut deeply, hillslopes carry rills, and gully and stream bank erosion after heavy rain is the main reason rock goes in.

This part of the state has the longest working season in Iowa, but clay soils need to dry before anything gets compacted. A wet spring pushes base work back several weeks, so time your delivery around that.

Cold winters bring repeated freeze and thaw, milder than the north but still enough to heave gravel drives and lanes every spring. Iowa building officials set footing depth by local rule.
