The Integrated Drain Gate Seawall System (IDGSS) was designed to mitigate flooding due to rising sea water, severe rain and storm damages at costal area or other various waterfront properties like riverbanks, bay, beach, ocean, lake, marsh and low lying areas. The IDGSS has incorporated two functions simultaneously by separating water and land with a flood resilient fixed water barrier wall, but more importantly, has an automatic drainage system, especially for an unexpected severe and prolonged storms; to address the unintended consequence of trapping water inside the pre-existing water barrier walls. Unfortunately, during these severe storms, the trapped water has created a bathtub like scenario by the manmade fixed wall barriers, and causing an insult to an injury to an already devastated storm conditions, due to a lack of drainage systems. To mitigate this type of severe drainage problem, IDGSS was created with a characteristics of a concrete wall blocks, which includes a one-way valve or flap drain gate inside as a single unified structure, with an adjustable one-way valve or flap drain gate specification; with a various shape, sizes, materials and configurations for both one-way valve or flap gate and wall blocks; and adaptable retrofitting mechanisms to meet the site specific topography and special drainage needs.
