Where we dig in the San Bernardino valley

Ten cities and county areas, each with its own ground, permit office and typical jobs.

Shandin Excavation covers the east valley out of San Bernardino. The order below is not by distance. It is by how much excavation work each city generates: housing age and the sewer laterals that come with it, lot size and septic, the fan cobble that changes the method, pool demand, hillside grading.

Cities and areas

San Bernardino
The hub city itself: 65,000 or so housing units, most built between 1950 and 1979 on clay tile and cast iron laterals, hillside lots under Shandin Hills and in Verdemont, and the strongest ADU permitting in the county.
Highland
East Highlands Ranch and the Seven Oaks Dam alluvial fan: the cobble and boulder ground that makes pool digs and ADU pads the hardest in the valley, plus high property values and steady pool demand.
Redlands
The oldest and most valuable housing in the valley: south Redlands craftsman and ranch stock from 1900 to 1960 on original laterals, orange grove parcels converting to pads and ADUs, and strong pool demand on big lots.
Yucaipa
Large semi rural lots, the highest septic share of any valley city, horse properties, and hillside grading in Chapman Heights and the Oak Glen foothills. Septic and pad work as much as pools.
Rancho Cucamonga
Alta Loma and Etiwanda sit on the coarsest alluvial fan in the Inland Empire, with boulders in nearly every dig, paired with the highest property values and pool spending in the service area.
Fontana
The fastest growing city in the service area with heavy pool demand in the newer north tracts, ADU conversions on the large older south Fontana lots, and light industrial pad work along the logistics corridor.
Rialto
A 1950s and 1960s housing core on aging clay laterals, large lots in north Rialto that take ADUs, and sandy Lytle Creek fan ground that keeps costs near the bottom of the range.
Colton
The oldest housing in the valley after Redlands, much of it pre 1950 on original laterals, clay rich river bottom soil near the Santa Ana, and small commercial and rail adjacent sitework.
Loma Linda
South Hills hillside lots that need engineered pads and cut slopes, a steady rental ADU market driven by the university and medical center, and 1960s ranch stock on aging laterals.
Devore
Unincorporated county land at the mouth of Cajon Pass: septic on every parcel, horse and acreage properties, Cajon Wash sand and cobble, and the county grading and septic rules rather than a city.

Not on the list? Grand Terrace, Mentone, Muscoy, Bloomington and the Crestline side of the mountain get the same crews. Call the number on the contact page and say where the lot is.
