Grading and Retaining Walls in Eagle Mountain

Eagle Mountain wall rules, in plain words

Eagle Mountain's Building Department spells out its retaining wall rule in a handout, and the details matter. A wall under 4 feet tall, counting the 30-inch footing depth, does not need a building permit. It still has to meet the zoning rules in city code 17.60. Go taller than 4 feet and you need a permit plus engineered drawings. No wall in the city can rise more than 6 feet from finished grade to the top.

That footing detail catches people. Because the buried part counts, a wall that shows only about a foot and a half above the dirt can already be near the line. We measure the whole wall, not just the face you see. When a design needs a permit, the application goes in through the city's online portal with a site plan showing distances to your property lines, construction plans and the engineer's drawings.

The ground itself is kinder than in a lot of Utah County. USU describes the native soil here as well-drained and not prone to ponding. The trouble is what happens during the build. Crews strip the topsoil, pack the lot with equipment and leave grades that tip back toward the house. Lots near the base of the Lake Mountains add real slope on top of that. We shoot the grades, fix the fall away from the foundation and build walls with drain rock behind them.

Eagle Mountain is two climates in one city, the milder Ranches by the Lake Mountains and the colder City Center out toward Fairfield, with open Cedar Valley wind, metered city water and a one-year clock on new front yards.

The Eagle Mountain challenges

Grading problems we see in Eagle Mountain

Packed lots that shed water

Native ground here drains well, but a lot that loaders drove over for months does not. Water from snowmelt and sprinklers sheets off the hard surface and heads for the lowest spot, which is often a window well or the side yard. Loosening the ground and regrading fixes most of it.

Forgetting the buried footing

Eagle Mountain counts the 30-inch footing depth toward the 4 foot limit. A crew that measures only the visible face can build a wall that needed a permit and engineering and got neither. That tends to surface at resale or when the city notices. We measure from the bottom of the footing every time.

Slopes below the Lake Mountains

Lots along the base of the Lake Mountains can climb fast. Cutting a flat yard into that kind of slope means walls, and the 6 foot cap above finished grade limits how tall any one wall can go. Terraces with planted steps usually work better than one big wall anyway.

Bare slopes in a dust storm

A freshly graded slope with nothing on it is an easy target. Dry spring wind strips fine soil right off it, and this valley has blown enough dust to close the main road through town. We cover finished slopes with rock or planting as soon as the grading is done.

The J&H approach

How we grade and build walls here

1 How we handle it

Measure the real grades

We shoot elevations at the house, the lot lines and the street, and set a fall away from the foundation all the way around. Then we decide where water leaves the lot, so it is not dumped on the neighbor below you.

2 How we handle it

Design inside the city's lines

We plan wall heights around the 4 foot permit line and the 6 foot cap from the first sketch. If the yard needs more height than that, we split it into terraces or work with a licensed engineer and file the permit.

3 How we handle it

Drain every wall

Every wall we build gets a compacted base, clean drain rock behind it and a perforated pipe that lets water out. Water trapped behind a wall freezes and pushes, and nights near City Center get very cold. Drainage is what keeps a wall standing.

Eagle Mountain questions

Grading and Retaining Walls in Eagle Mountain: what people ask

Does my retaining wall need a permit in Eagle Mountain?
If it is taller than 4 feet, counting the 30-inch footing depth, yes. That takes a building permit and engineered drawings. Under that, you skip the building permit, but the wall still has to meet the city's zoning rules. No wall can be more than 6 feet from finished grade to the top. We check the current rules with the city before any wall goes in.
Can you grade the steep part of my lot?
Usually, with care. The city has considered limits on grading ground steeper than 25 percent, and in developer and commercial work grass is not allowed on slopes that steep. We check what applies to your lot with the city before we cut, then plan terraces, rock or low-water planting for the slope.
Water collects by my foundation. Is that a grading problem?
Most of the time. Eagle Mountain's native soil drains well, so standing water by the house usually means the builder left the grade flat, tipped it the wrong way or packed the ground hard. We regrade so the soil falls away from the house and add a swale or drain where it is needed.
