Completed in 2003, this earth dam stands at a height of 30 feet and has a length of 2300 feet. Its primary purpose is flood risk reduction, with a storage capacity of 490 acre-feet and a maximum discharge of 2076 cubic feet per second. The dam is situated on Waikapu Stream and is regulated by the Department of Land and Natural Resources (DLNR) in Hawaii.
Despite its crucial role in mitigating flood risks, the Kehalani Offsite Retention Basin is currently assessed as having a high hazard potential with poor condition. The last inspection in May 2020 indicated the need for improvements, highlighting the importance of proactive maintenance and risk management measures. While it has undergone no modifications since completion, its emergency action plan (EAP) status, including contact information and inundation maps, is currently not up-to-date, raising concerns about its readiness in case of emergencies. As water resource and climate enthusiasts, it is essential to monitor and advocate for the proper maintenance and upkeep of this vital infrastructure to safeguard the surrounding community and environment.
