There is a big difference between sitting under a shady tree and sitting under an umbrella on a hot and sunny day. It is so much cooler under the tree because it will absorb some some of the heat. The umbrella won’t. That is why a harder wood would be a better material than synthetic for the new boardwalk. A synthetic boardwalk is going to be hot. It’s not going to absorb heat.
Just another reason why The City of Long Beach should consider a new harder wood over a synthetic for the new boardwalk.
