Retaining Walls in Dixon, CA

Retaining Walls · Dixon, CA

Block and stone walls with drain rock behind them

Retaining walls hold back soil where the ground steps from one level to another. Trinity Paving and Concrete builds block and stone retaining walls along driveways and slopes around Dixon. A turnaround cut into a hillside can need one too. Each wall starts on a compacted base, with drain rock and perforated pipe behind it.

The dirt work around the wall is part of the job. So is the grading that sends water away from it. Call or text (707) 396-7730, and we will look at the slope and put the quote in writing.

Block and Stone Retaining Walls Along Driveways and Slopes

A driveway cut into a slope leaves a bank of soil beside the pavement. A retaining wall holds that bank back and keeps the soil off the drive. Where a drive is built up above the yard, a wall can hold up its low side.

Block units are made to matching sizes, so they stack in straight, even courses. Stone comes in natural shapes, and each piece is set to fit the ones around it. Either way, the soil behind the wall goes back in compacted layers.

When a new drive goes in beside a wall, we can build both. We pave asphalt driveways and pour concrete driveways. Where the wall holds up the drive, the wall and its backfill go in before the base for the drive.

Why Does a Retaining Wall Need Drain Rock and Pipe?

Rain that soaks the soil behind a wall adds water pressure to the weight of the soil. Dixon's retaining wall handout calls for drains behind permitted walls to relieve that pressure. It names a 4-inch perforated drain line and a 12-inch gravel pocket.

NOAA normals for Davis, a few miles north, put 84 percent of the year's rain between November and March. Dixon also has expansive clay in places. It swells when wet, and NRCS says water moves through it slowly.

Our walls get drain rock behind them and perforated pipe along the base, with outlets to carry the water out. A concrete masonry trade group's guide for block walls calls for an outlet at least every 50 feet. It also advises against pea gravel, a round single-size stone, for the gravel fill.

When Does a Retaining Wall Need a Permit in Dixon?

Section 105.2 of the California Building Code exempts a retaining wall 4 feet tall or less from a building permit. The height runs from the bottom of the footing to the top of the wall. A wall that stands 3.5 feet above the ground on a footing 1 foot deep measures 4.5 feet. That wall needs a permit.

The exemption ends when the wall supports a surcharge, an added load on the soil it holds back. Dixon's handout counts sloping soil above the wall as one. Within 10 feet of a slope of 20 percent or more, Dixon drops the limit to 30 inches.

Dixon's Building Division and Planning Division have separate requirements for retaining walls. Work in the public right-of-way takes a separate encroachment permit from the Engineering Department. The building office for your address answers the permit question, and we point you there before the wall goes in.

Grading and base work

On a replacement, the old asphalt is torn out and hauled off first. Then the ground is graded, and base rock goes down in compacted lifts.

FAQ

Retaining Walls Questions, Answered

Common questions about retaining walls around Dixon and the towns of Solano, Yolo and Sacramento counties. If yours is not here, call or text and ask.

Call (707) 396-7730

How much does a retaining wall cost?
The price follows the length and height of the wall and the choice of block or stone. Digging into the slope and the drainage behind the wall add to it. We look at the slope and the access, then put the quote in writing. Call or text (707) 396-7730 to set that up.
Does a short wall beside my driveway need a permit?
It can, when the wall holds up the drive and the weight of cars sits on the soil behind it. Dixon's handout counts those vehicle loads as a surcharge. A wall with a surcharge needs a permit there, even under 4 feet. Sacramento County's building division applies the same rule to walls under vehicle loads.
Do I need an engineer for a retaining wall?
In Dixon, a wall that needs a building permit needs plans stamped by an engineer or an architect. The exception is a wall built to a city-approved design. Sacramento County's building division asks for structural calculations stamped and signed by an engineer. Other offices set their own plan rules, so ask yours first.
Can a retaining wall go on the property line?
It depends on the town. In Vallejo, the city keeps retaining walls on the property line or on private land, out of the public right-of-way. In Dixon, a permitted wall planned to encroach on a property line needs a survey by a licensed land surveyor. Dixon's handout also says water may not drain onto adjoining property or walkways.
Why do retaining walls lean or bulge?
A wall holds back soil and the water in it. Water that cannot drain adds pressure, and loose fill or a soft base can let the wall move. For block walls, a concrete masonry trade group's guide calls for compacted backfill layers of 8 inches or less. So we compact the base before the first course goes down.
