Highways, expressways and heavy vehicles
Highway 101, Lawrence Expressway, El Camino Real and Highway 237 run through or beside the city, and many business sites have truck access from these routes. Delivery vans, tractor-trailers and service vehicles move across drive aisles that were designed for lighter loads.
Repeated heavy turns scuff and rut asphalt, especially at the edges of loading zones and gates. Utility trenches across lots often settle and leave long, narrow depressions. Water pools in those lines and works into the base. We look for these patterns on a walk-through, since fixing the cause is more lasting than patching the surface.
