of Brooklyn’s Brighton Beach/
Coney Island boardwalk were re-
placed with concrete slabs as a
pilot study”. Calling a project a
pilot study” basically means that
it can move forward with just
about zero oversight. The only
thing that is really needed is the
green light from an obscure City
agency called The Design Com-
mission. Composed of Mayoral
appointees, the people on the
commission are museum board

Concrete has long been used in
offshore breakwaters, to concen-
trate wave energy. The wave hits
the concrete with all of its force,
so the water that travels towards
the beach is much calmer. But
this comes at a price. The force

erodes the sand at the base of
the structure.

their concerns about increased
beach erosion in a hurricane,
they were told that they had
nothing to worry about – a storm
surge would NEVER hit the

boardwalk!
Well, the rest is history.

Concrete: Several feet of ero-
sion underneath the slabs.
Eight to ten feet of sand on
the streets next to it. No
sand on top of the slabs. This
suggests that the storm surge
did not slow down as it went
over the concrete.
Wood: Sand piled up to the level
of the boards, no erosion under-
neath. Mere inches of sand on
the adjacent street. Several inch-

Wooden boardwalks are a delight

common sense is used before
replacing them.
