Concrete leveling in Derby, KS
Derby gets the same sunken driveway panels and sidewalk lips as the rest of the Wichita area, and two local details shape how they get fixed: the city's own sidewalk rules, and the clay soil that covers much of the town. Calls from Derby go to the same independent contractor who serves the rest of the area.

We clipped the USDA soil survey to Derby's city limits. About 46 percent of the soil area inside the city has a layer within five feet rated high or very high for shrink-swell, compared with about a third across Sedgwick County as a whole.
The most common soil in Derby is Irwin, a clay soil rated high, which covers about 36 percent of the city's soil area. Next is Vanoss at about 30 percent, rated moderate, and Elandco at about 12 percent, a flood plain soil rated low. Irwin is an upland soil and Elandco forms on flood plains, so two slabs a mile apart in Derby can sit on very different ground.

Derby's sidewalk rules
Derby's code follows Kansas law in making the owner of the property next to a sidewalk responsible for keeping it in repair. When the city sends a notice, the owner has five days to start the repair unless the notice gives more time. If nothing is started, the city can make the repair through its sidewalk repair program and assess the cost against the property.
Five days is the time to start, so it is worth calling soon after a notice arrives. Derby also requires a permit from the city engineer before anyone cuts or removes part of a public sidewalk or street, or paves a driveway approach in the right of way. Replacing a sidewalk square falls under that rule. Leveling raises the square without removing it, but if you are unsure whether your job needs a permit, ask the city engineer's office before work starts.

What that means for a Derby driveway or walk
- Clay soil rewards good drainage. On Irwin and similar soils, the slab moves most where water gets under the edge and then dries out. Downspout extensions and sealed joints do a lot of the work of keeping a leveled slab where it is.
- Fix before winter when you can. A void left open going into the freeze and thaw season tends to grow. See the best time of year to level.
- Raised is different from sunken. Clay can also push a slab up. Leveling raises low concrete but cannot lower a slab that has heaved.
- For the soil and weather data behind all of this, see why concrete sinks in Wichita.
Questions people ask

The owner of the property next to it. Derby's code says so, following Kansas law, and the city can make the repair and assess the cost to the property if the owner does not act after a notice.
How long do I have after a Derby sidewalk notice?
