The Lucy Evans Baylands Nature Interpretive Center Boardwalk, which runs between the center and the bay, has been closed due to unsafe structural conditions, John Aiken, the executive director of the Palo Alto Junior Museum and Zoo, said Thursday.
Aiken said that a support piling underneath the boardwalk, which was built in 1969, separated from the structure earlier this week. This is the second separation of this nature.
"There was one that made (the boardwalk) sort of springy before," he said. "So now, we're concerned that it may be a structural issue."
He said that staff has been doing repairs on the boardwalk every year for decades.
"It's a bit of a catch-up battle -- the weather and the marine environment and the marsh gets ahead of us," he said. "So we are evaluating this current structural failure and we are putting together a plan to have it very formally evaluated and figure out what the best course of action is in terms of larger scale repairs or replacement."
Aiken said it's too early to tell when this might happen or how much it will cost, but he's currently working with the city's Planning Department and Department of Public Works to evaluate out what the best route forward might be.
