About the area
The populated southwest corner of San Bernardino County is the Inland Empire's commercial center: the Haven Avenue office corridor in Rancho Cucamonga, the business district around Ontario International Airport, San Bernardino's Hospitality Lane, and the largest concentration of distribution centers in the country. Guardian serves this corridor along the 10, 15, 60, and 210.
Large sites are the norm here. Logistics parks measure their lots in acres, office parks share campuses, and retail centers like Victoria Gardens and Ontario Mills draw regional traffic. Our routes are built for that scale: crews and equipment sized to the property, and schedules that keep large hardscape areas on a predictable rotation.

Our direction
Our direction in San Bernardino County
Scale is the defining condition. Logistics parks, regional retail, and the Haven Avenue office corridor all run on large sites, so we scope by zone: entrances and tenant frontage get frequent attention, back lots and truck courts get a rotation sized to their traffic. Post-wind debris cleanup after Cajon Pass events is a standing task on every route.

Local conditions
What San Bernardino County properties deal with
Cajon Pass winds
Santa Ana events funnel through the pass and hit Rancho Cucamonga, Fontana, and San Bernardino hardest. Post-wind debris cleanup is routine.
Truck traffic
Logistics parks and the routes to them carry heavy diesel and tire deposits onto adjacent retail and office hardscape.
Scale
Sites here are large. We scope by zone so entrances and tenant frontage get more frequent attention than back lots.
Questions
San Bernardino County FAQ
Do you cover the High Desert?
Not on recurring routes. We serve the populated valley corridor from Chino and Ontario through Rancho Cucamonga, Fontana, and San Bernardino to Redlands.
Can you handle a logistics park's parking and truck courts?
Yes. Large-format hardscape is scoped by zone and washed on a rotation, with oil and diesel pre-treatment where trucks stage.
Do you serve both Inland Empire counties?
Yes. Riverside County has its own page; portfolios that span both are run on one schedule.
