As has been stated elsewhere, before Pompano had been incorporated eight years, it had been a part of three counties (Dade, Palm Beach and Broward).

Those who led the effort to create Broward County originally proposed that the northern boundary follow the Hillsboro canal all the way to Lake Okeechobee. This was unacceptable to the leaders of Palm Beach County, and so it was agreed that the new county's northern boundary would run along the Hillsboro canal about ten miles (to a point west of today's State Road 7) and then run directly west to the boundary of what was then Lee County (Hendry County wasn't created until 1923).
