Together with the SRDC, the engineers spent much of their time thinking about how to place the boardwalk in the river. In the end, they located it 50 feet from shore, far enough out that you really feel you're on the water, but not so far that it interferes with boat navigation. The walkway hovers six to 12 feet above the water, depending on the tides, and is designed to withstand the flooding that has become a regular occurrence on this part of the Schuylkill.
