Working in a dense city
San Gabriel has about 9,264 residents per square mile. In blocks like these, surveillance usually needs more planning: parking is limited, buildings have several entrances, and people move by transit or on foot. A second detective is sometimes the difference between keeping someone in view and losing them at a corner, so that choice is discussed when scope and cost are set.
Interstate access and travel
Interstate 10, Interstate 210 and Interstate 710 run through or near San Gabriel. Subjects in a mobile surveillance often leave town on these routes, so plans account for highway speeds, exits and where the work could cross into another jurisdiction. The same routes matter for locates: people who move frequently tend to follow them.
Business and workplace matters
The largest employment sectors among San Gabriel residents are education, health care and social assistance (21%), arts, recreation, lodging and food service (12%) and professional, scientific and management services (11%).
