However possible, have the seat of Congress be Staten Island (owned by the Federal Government and donated by New York State), rather than on the Potomac. The area was sparsely populated at the time, but, like the eventual spot chosen, has port access and some settlement on the extreme ends of the island.
The only restriction is that have it be done before the Potomac spot is selected.
