Colton is a railroad town, and the houses near the yards and along Mount Vernon date to the 1900s through the 1940s. The sewer laterals under them are the oldest in the service area, often clay with cast iron under the house, and some of the deepest because the mains were set to drain toward the river. Shandin Excavation handles the dig, the shoring that a deep trench needs under Cal/OSHA rules, and the backfill the city inspects.
The ground changes as you move toward the Santa Ana River. Downtown and Cooley Ranch sit on sandy loam, but the river bottom lots along La Cadena and south of the 10 carry clay lenses and a seasonally high water table. A trench that stands fine in Rialto sand can slump here after a wet week, so timing and dewatering come up in the quote.
Reche Canyon on the south edge is a different world: rural lots, some on septic, horse property and cut slopes. Pad grading and septic excavation there is priced like Yucaipa, not like downtown Colton.
Old pipe, deep mains, river clay
Colton owns and runs its own sewer utility, and the Colton inspector wants to see the lateral connection at the main before it is covered. The crew calls it in at the start of the dig so the inspector arrives as the pipe is being set, and nobody waits with a trench open.

Colton questions
Why are Colton sewer laterals so deep?
The original mains were laid to drain by gravity toward the Santa Ana River, so on the flatter blocks downtown the main can sit 10 to 12 feet below the street. Anything over five feet needs shoring or sloped walls, and that is the main cost driver on a Colton lateral.
Does the water table affect digs near the river?
In a wet winter, yes. Lots south of the 10 near La Cadena can see water a few feet down from January through March. A pool dig or deep trench there is scheduled for the dry months when possible, or priced with a pump.
Can you excavate for a small commercial addition in Colton?
Yes. Footings, utility trenches and pad grading for shop additions and yards along Mount Vernon and La Cadena are a regular part of the schedule. Those are quoted by the hour or by the yard after a site visit.
Is Reche Canyon on septic?
Much of it is. Replacement systems there are reviewed by the City of Colton for the parcels inside city limits and by San Bernardino County Environmental Health for the unincorporated stretch, so the first question is which side of the line you are on.
Shandin Excavation covers the whole east valley. See the cost guide, the pool excavation page, or nearby areas: Loma Linda, Devore, San Bernardino.
