I am against building a seawall there, although I am an avid golfer and would like to see Wailua preserved as much as possible. Seawalls are expensive to build, and in our case the approximated cost is five million.
These seawalls are built parallel to the shore with the idea that it will protect the shoreline and slow erosion, but just the opposite is going to happen if a seawall is built. First the seaward side of the wall begins to erode with all of the wave action.
Then slowly the seawall will diminish into the ocean, and in result the oversteepened beach slope will move inward toward land.
(Finally I would like to take a quote from Thurman & Trujillo Essentials of Oceanography textbook) which states the negative effects of a seawall. “Where seawalls have been used to protect property on barrier islands, the seaward slope of the island beach has steepened and the rate of the erosion increased, in essence seawalls destroy recreational beaches.”
