Local considerations
Investigative considerations in Summit.
City blocks and busy streets
Summit has about 5,118 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.
Major routes through the area
Interstate 55 and Interstate 294 run through or near Summit. 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 Summit residents are manufacturing (19%), education, health care and social assistance (14%) and professional, scientific and management services (13%).
