Beachfront lands are the site of intense residential and commercial development even though they are highly vulnerable to several natural hazards, including marine inundation, flooding and drainage problems, effects of storms, sea-level rise, and coastal erosion.

Due to global warming and continuous increase in emission of greenhouse gases from human activities results in further changes and greater risks in the natural systems.Among these risks are negative impacts related to Sea Level Rise which is due to winds, ocean currents, continental runoff, salinity, gravity and other factors. Thus, a design is proposed to restore the quality of the beaches naturally.

Ala Wai Canal was built to drain all the Waikiki living waters to the canal which was considered unsanitary. Due to its shallow depth and single outlet, water overflowed during heavy storm events with 1M SLR flooding the city with dirt. Waikiki receives 11 flash floods a year on an average. Thus, the water flows through the neighborhood and pollutes the water from the canal. To prevent the pollution of canal and then the beaches, the wetlands are re-introduced to the golf course that not only diverts the flow of water from getting into the canal directly, but also, reduces the flow and treats the water as it passes through the wetlands and swales. This also prevents the beaches from getting polluted and flooded. Furthermore, it enhances the quality of the water and creates a recreational and educational zone for the city.
