Summary We surveyed actual situation on coastal drainage facilities such as drainages, retarding basins, secondary parapets and pump stations, and proposed a design procedure of coastal drainage facilities. The procedure includes flowcharts of drainage planning based on wave overtopping rate and precipitation, performance design of each facility, and maintenance planning.
