Working in a dense city
Portland has about 3,197 residents per square mile. Apartment buildings with several exits, limited parking and foot and transit traffic all make observation harder to sustain with one person. Staffing is decided up front, when scope and cost are agreed.
Interstate access and travel
Interstate 295 and U.S. Route 1 run through or near Portland. 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.
Waterfront and shoreline
About 69% of Portland's total area is water. Waterfront property, docks and boats can all be part of asset or property research, and shoreline geography affects where observation can lawfully happen.
