The U.S. Army Corps of Engineers (USACE) Honolulu District completed an Engineering Documentation Report Aug. 6 that provides the new recommended plan for the Ala Wai Flood Control Project.
The new plan incorporates significantly less impacts on the natural streams and residential properties within the watershed, and focuses on evacuating the water without detaining it in the upper reaches of the watershed valleys. Using this report as the foundation, the project team will now begin the evaluation of costs, economic benefits, and environmental impacts through a supplemental National Environmental Policy Act (NEPA) and Hawaii Environmental Policy Act process (HEPA) process.
Honolulu District Commander Lt. Col. Eric S. Marshall signed the report, a technical evaluation of the flood control system with modifications designed during the past year. The report reflects many concerns heard from Ala Wai communities, improves design concepts, and is prepared to support the Project Partnership Agreement (PPA). The City and County of Honolulu and USACE, comprising the project team, must eventually sign a PPA before construction of a final Ala Wai project can begin.
The report and a map showing the current proposed project design changes and new feature recommendations are available on the Ala Wai project web page: https://go.usa.gov/xfARb.
