Presidio Coastal Trail (Completed Spring 2012)

Constructing Box Steps and Boardwalk Piers on Presidio's Mt. Lake Trail

Caleb and Jesus fill the hand-dug piers for the boardwalk with concrete. The boardwalk will connect the box steps (see below) coming up from Wymann Ave to the Merchant Marine Cemetary Vista, which overlooks the newly constructed sand dunes near Battery Caulfield Road. The piers minimize impact on the adjacent tree roots.

The combination of box steps and landings allow the trail to fit into the contours of the hillside. They are built in a way that reduces sediment erosion, and are constructed to avoid any large tree roots from the adjacent cypress and oaks.
