Notice of availability.
The U.S. Army Corps of Engineers (USACE) announces the availability of a Public Review Final Feasibility Study with Integrated Environmental Impact Statement (EIS), for the Ala Wai Canal Project, Oahu, Hawaii. The Final Feasibility Study/EIS evaluates alternatives to manage flood risk within the Ala Wai watershed, which includes the neighborhoods of Makiki, Manoa, Palolo, Kapahulu, Moiliili, McCully, and Waikiki. It also documents the existing condition of environmental resources in areas considered for locating flood risk management features and potential impacts on those resources that could result from implementing each alternative. The State of Hawaii, Department of Land and Natural Resources is the non-Federal sponsor and the proposing agency for compliance with the Hawaii law on Environmental Impact Statements.
All written comments must be postmarked on or before June 25, 2017.
Written comments may be submitted to the Ala Wai Canal Project, U.S. Army Corps of Engineers, Honolulu District, ATTN: Derek Chow, Chief, Civil and Public Works Branch (CEPOH-PP-C), Building 230, Fort Shafter, HI 96858-5440 or via email to AlaWaiCanalProject@USACE.Army.mil.

Proposed Action. The proposed Ala Wai Canal Project, Oahu, Hawaii feasibility study is a single-purpose flood risk management project to reduce riverine flood risks to property and life safety in the Ala Wai Watershed. The Ala Wai Canal Watershed is located on the southeastern side of the island of Oahu, Hawaii. The watershed is 19 square miles and encompasses three sub-watersheds of Makiki, Manoa and Palolo Streams, which all drain into the Ala Wai Canal. The study area includes the most densely populated watershed in Hawaii with approximately 200,000 residents in the developed areas. In addition, Waikiki supports approximately 79,000 visitors on a daily basis.
This study was authorized under Section 209 of the Flood Control Act of 1962 (Pub. L. 87-874), a general study authority that authorizes surveys in harbors and rivers in Hawaii “with a view to determining the advisability of improvements in the interest of navigation, flood control, hydroelectric power development, water supply, and other beneficial uses, and related land resources.”
Alternatives. The Final Feasibility Study/EIS considers a full range of nonstructural and structural flood risk management alternatives that meet the proposed action's purpose and need and incorporate measures to avoid and minimize impacts to native aquatic species, stream habitat, and other resources. In response to identified flood-related problems and opportunities, a range of alternatives were evaluated through an iterative screening and formulation process, resulting in identification of a recommended plan.
The recommended plan is the National Economic Development (NED) Plan and consists of the following components: Improvements to the flood warning system, 6 in-stream debris and detention basins in the upper reaches of the watershed, 1 stand-alone debris catchment feature, 3 multi-purpose detention basins in open space areas through the developed watershed, floodwalls along portions of the Ala Wai Canal, mitigation measures, and 2 associated pump stations to maintain internal drainage. Canal floodwalls would extend approximately 1.7 miles along the left (makai) bank and approximately 0.9 mile along the right (mauka) bank (including gaps for bridges).
Public Involvement. As part of the current public involvement process, all affected Federal, State, and local agencies, Native Hawaiian organizations, private organizations, and the public are invited to review and comment on the Final Feasibility Study with Integrated EIS. Comments may also be submitted as described in the DATES and ADDRESSES sections.
Other Environmental Review Requirements. To the extent practicable, NEPA and HRS Chapter 343 requirements will be coordinated in the preparation of the Final EIS.
