Derby sits on the Arkansas River valley in southern Sedgwick County, and many of its homes have long side drives, RV pads and parking strips that see a lot of traffic. A gravel driveway is one of the most practical surfaces you can build here. It drains quickly after a summer storm, it is easy to repair, and it costs far less than concrete. The catch is that a gravel driveway in Derby, KS only lasts when the layers underneath are right. If you are ready to order, you can see every material we deliver on our Derby gravel delivery page.
This guide walks through the build from the ground up: preparing the soil, choosing each layer, and keeping the surface smooth for years.

Why the Base Matters for a Gravel Driveway in Derby
Most problems people blame on “bad gravel” actually start below it. Derby gets heavy spring and early summer rain, and the ground under a driveway softens when water sits in it. Wheels then push the stone down into the soil, ruts form, and puddles grow every time it rains. Sedgwick County also uses a frost depth of about 30 inches for footings, so winter freeze-thaw cycles lift and loosen a thin, poorly drained surface.
A good driveway solves both problems the same way: a firm, crowned subgrade, a thick layer of angular base stone that locks together, and a finer top layer that sheds water to the edges.
- Bottom layer → crushed run
- Main base → road base gravel
- Driving surface → 3/4″ minus base gravel
- Edges and low spots → #57 stone for drainage

Best Materials for a Derby Gravel Driveway
| Layer | Recommended material | Why it works |
|---|---|---|
| Sub-base on soft ground | Crushed run | Large angular pieces bridge soft spots and spread wheel loads |
| Main base course | Road base gravel | Stone and fines compact into a dense, rut-resistant layer |
| Top surface | 3/4″ minus base gravel | Packs smooth and firm without loose marbles of stone |
| Side drainage strip | #57 stone | Open voids let runoff soak away instead of pooling on the drive |
Stacking these layers in order gives you a driveway that drains, holds its shape and stays easy to top up.
Step 1: Prepare and Crown the Subgrade
Strip the sod and any dark, spongy topsoil until you reach firm ground. On most Derby lots that means removing four to eight inches. Shape the subgrade so the center sits slightly higher than the edges, about a quarter inch of fall per foot of width. That crown is what moves water off the driveway instead of letting it soak in. Compact the exposed soil with a plate compactor or roller before any stone goes down, and dig out any spot that still feels soft under your boot.
Step 2: Build the Base in Lifts
On wetter ground or where trucks and trailers will park, start with three to four inches of crushed run. Then add four to six inches of road base gravel. Spread and compact each layer in lifts of about three inches rather than dumping the full depth at once. Thin lifts compact all the way through. A thick pile only compacts at the top and settles later, which is where dips and potholes come from. Lightly wetting road base before compacting helps the fines bind the larger stone together.
Step 3: Finish With a Tight Top Course
Finish with two to three inches of 3/4″ minus. Its fine particles fill the gaps between the stones so the surface packs hard and does not roll under tires. Keep the crown you built into the subgrade all the way to the top. If water still collects along one side, a shallow trench filled with #57 stone along that edge gives runoff somewhere to go. Our road base gravel guide explains how base materials compare if you want more detail.
Keeping a Derby Gravel Driveway in Shape
Every gravel driveway needs a little care. Rake loose stone back into wheel tracks after heavy storms. Fill small potholes as soon as they appear: clean them out, add 3/4″ minus, and tamp it firmly. Every two or three years, spread a fresh inch of top course to replace what traffic and snow plowing have pushed aside. Neighbors in Haysville and Mulvane deal with the same river-valley soil, and the same routine works there.

How Much Gravel Will Your Driveway Need?
Measure the length and width of the driveway in feet, then multiply by the depth of each layer in inches and divide by 324. The result is cubic yards. Most crushed stone weighs roughly 1.4 tons per cubic yard, so multiply by 1.4 if you are ordering by the ton. For example, a 60-foot by 12-foot driveway with a 6-inch road base layer needs about 13.3 cubic yards, or around 19 tons. Order a little extra to allow for compaction.
FAQ
How thick should a gravel driveway be in Derby?
Plan on 8 to 12 inches of total stone: a crushed run or road base layer below and two to three inches of 3/4″ minus on top. Use the thicker end where trucks or trailers park.
Do I need landscape fabric under the gravel?
On soft or clay ground, a woven stabilization fabric under the first layer helps keep stone from sinking into the soil. On firm ground it is optional.
Why does my driveway keep getting potholes?
Potholes usually mean water is sitting in the driveway. Rebuilding the crown and adding a drainage strip on the low side fixes the cause instead of just the hole.
Can I use river rock or pea gravel on a driveway?
Rounded stone rolls under tires and never locks together. Use angular crushed stone for anything you drive on.
Final Thoughts
A gravel driveway in Derby can last for decades when the base is built in layers, compacted properly and crowned to shed water. Spend your effort on the ground prep and the bottom layers, and the surface will take care of itself with a little yearly upkeep. See more projects across the state on our Kansas service area page.
