Materials for Derby Projects

Decorative rock is where a lot of Derby ground work starts: beds, borders, tree rings and dry creek beds. Rounded stone reads well against a house and moves water along a swale.

River Rock is washed river gravel, rounded by moving water. Use it in decorative beds, along borders and in dry creek beds.

Large River Rock is the oversized grade of the same rounded stone. It suits dry creek beds, splash pads and heavier bank work.

3/8" Natural Pea Gravel is small rounded gravel. It fits walkways, play areas, patio bedding and small drainage runs.

For a drive or a pad, start with a compacted base. Class A Roadstone is 3/4 inch crushed limestone with the fines left in, so it binds and compacts under driveways, parking pads, shed bases and farm lanes.

Where a new drive or a soft spot needs a coarser start, 1 Inch Roadstone lays under a finer surface course. For drainage, Clean Rock is washed and open graded, so water moves straight through subdrains, pipe bedding and retaining wall backfill.

Beds and gardens take soil and mulch. Top Soil is screened black dirt for lawn repair and bed prep, and Shredded Mulch holds moisture through a dry Iowa August.

Ground and Conditions in Derby

Derby sits on the Southern Iowa Drift Plain. Under the topsoil is old pre-Illinoian till beneath a windblown loess mantle, and below that a thick grey clay paleosol that water will not move through.

That clay is why ground here perches water instead of taking it. A drive at the bottom of a grade goes soft after spring rain, and the surface drains while the subsoil holds.

This is also Iowa's most eroded landscape. Streams cut deep, hillslopes carry fine rills, and gully and stream bank erosion after heavy rain is why rock goes in on slopes and at culvert outlets.

Riprap armors those spots. Riprap is large angular stone for stream banks, culvert outlets, pond edges and slope protection against spring runoff.

Timing matters as much as material. The working season here is the longest in the state, but clay soils need to dry before anything gets compacted, so a wet spring pushes base work back several weeks.

Cold winters bring repeated freeze and thaw, enough to heave gravel drives and lanes every spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.
