New recommended system for Ala Wai project evaluated in technical report
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. The report and a map showing the current proposed project design changes and new feature recommendations are available on the Ala Wai project webpage: https://go.usa.gov/xfARb.
