Presidio Coastal Trail (Completed Spring 2012)

El Polìn Boardwalk Construction

The boardwalk at El Pol

ìn under construction. The boardwalk was strategically located by John Roberts Landscape Architects to allow spring flows and seepages from the adjacent hillside into the central channel within the loop. In order to stabilize the boardwalk, (30) 7'-5" deep x 18" diameter piers were required. The beams were then installed between the piers, the headwalls were framed and poured on either end, and now the 4"x12" sustainably harvest decking is being installed.
