Did you know that the beaches of Waikiki are the result of past coastal engineering efforts? This “highly engineered urban shoreline” is the result of a variety of activities such as beach nourishment, groins, seawalls, and other coastal engineering projects. Today, this vital economic driver of the state’s visitor industry is being threatened by climate change. This collaborative walking tour between the State and the City and County of Honolulu will explore the rich history of Waikiki beaches while also discussing current management and future proposed projects. We will visit various locations from the Queen’s Beach seawall to the Fort DeRussy groin and discuss their histories, current situations, and future proposed projects. Lunch provided.
