Abstract
-
The Ala Wai Canal Flood Risk Management Project completed the Feasibility Stage in December 2017 when the Chief of Engineers for the US Army Corps of Engineers submitted the Chief's Report to Congress. The Record of Decision for the Environmental Impact Statement was signed by the Assistant Secretary of the Army for Civil Works in September 2018 and was transmitted to the state of Hawaii for adoption. The Pre-construction, Engineering, and Design (PED) phase was funded by the Bi-Partisan Budget Act of 2018 under the Long-term Disaster Recovery Investment Program with an authorized cost of $345,076,000. Updated analysis conducted during the PED phase were summarized in the 2020 Engineering Documentation Report (EDR). The EDR provided the technical basis for modifications necessary to the authorized project. Subsequent analysis found that the modifications in the 2020 EDR were not cost effective and lacked the economic justification necessary for continued federal involvement. The PED phase was terminated in early 2021.
