The I-15 runs along Escondido's west side, linking the city to Rancho Bernardo and San Diego to the south and to Temecula to the north, and SR-78 crosses it heading west through San Marcos and Vista to Oceanside. East of downtown, SR-78 continues as the road through the San Pasqual Valley toward Ramona, while Valley Parkway and Valley Center Road lead north into the hills. Centre City Parkway, Escondido Boulevard, Mission Avenue, El Norte Parkway and Citracado Parkway carry most of the work traffic in town.
Outside the core, the driving changes. Grove and slope jobs mean narrow, winding two-lane roads where a loaded chip truck or a trailer full of mulch needs room to stop and has few places to pull over, and summer heat wears on tires and brakes. Yards are spread between the industrial areas near the I-15 and SR-78 and larger properties outside town.
Equipment moves with the work. A tree crew's day can start with a chip truck towing a chipper to a grove, then a bucket truck to a roadside job and a stump grinder on a trailer behind a pickup. Every towed unit belongs on the schedule with its value, and drivers who tow should run a written check of hitch, safety chains and lights before they leave the yard.
The San Diego County fleet insurance page covers the county's freeways and contract work, and how carriers see a five- to ten-truck operation is worth reading before a tree or landscape company adds its next crew.
