KAUAI EMERGENCY REPAIRS: HANALEI HILLS AND WAIKOKO
AHUPUAA OF HANALEI AND WAIKOKO, DISTRICT (MOKU) OF HALELEA, ISLAND OF KAUAI, STATE OF HAWAII
FEDERAL-AID PROJECT NUMBER: ER-24(003)
TAX MAP KEYS: 5-6-003:002; 5-4-004:010; 5-3-001:007; 5-4-004:032; 5-3-001:002; and the right-of-way of Kuhio Highway in the vicinity of these listed TMKs
Notice is hereby given that the Federal Highway Administration (FHWA) and the State of Hawaii Department of Transportation, Highways Division (HDOT) propose highway and slope repairs. This federally funded HDOT project is considered a federal action and undertaking, as defined by Section 106 of the National Historic Preservation Act (NHPA) of 1966, as amended (2006).
In March 2021, landslides occurred at two sites along Kuhio Highway Route 560 on Kauai: Milepost (MP) 1, near Hanalei Bridge (Hanalei Site) and at MP 4.5, near Waikoko (Waikoko Site).
Emergency repairs were undertaken to address the immediate health and safety of the travelling public, and to restore roadway operations. This proposed project is in follow-up to the initial emergency. HDOT proposes to install soil nail retaining structures and anchored wire mesh as permanent repairs at the Hanalei and Waikoko sites. Soil and debris removed from these landslide sites would be deposited at stockpile locations in Princeville, as shown in the project location map.
In addition to installing soil nails and anchored wire mesh, slope stabilization at the Hanalei Site would also involve lining a historic tunnel that was exposed after the landslide. A drainage system would then be added to capture and re-direct water away from the tunnel and hillside. Drainage pipes may be placed along Kuhio Highway to the Hanalei River Bridge area or perpendicular to Kuhio Highway down the slope towards Hanalei River.
The proposed project is located in Halelea, Kauai. For the Hanalei Site, the area of potential effect (APE) consists of the Hanalei hillside below Kuhio Highway, where the slope slid down to Hanalei River, as well as portions of Kuhio Highway Route 560 (MP 0.0 to MP 1.5). Affected potions of the Highway are located about 250 feet to the east of the intersection with Hanalei Plantation Road and terminates at the southern bank of Hanalei River Bridge. The Hanalei Site APE also includes two flumes/tunnels extending northeast and northwest, an area for a drainage system directly along the upper portion of Kuhio Highway, and a construction staging and stockpiling area near the Hanalei River Bridge. For the Waikoko Site, the APE consists of the mauka slopes adjacent to Kuhio Highway about 900 feet north of Waikoko Stream Bridge, as well as the Highway itself from approximately MP 4.4 to MP 4.7. A stockpiling area in Princeville near Hanalei Transfer Station is also included in the APE. The Hanalei Site, Waikoko Site, and Princeville stockpile site cover an estimated 11.2, 0.95, and 10 acres respectively, for a total of approximately 22.15 acres included in the APE.
Pursuant to Section 106 of the NHPA, Native Hawaiian Organizations and Native Hawaiian descendants with ancestral, lineal or cultural ties to, cultural and historical property knowledge of and/or concerns for, and cultural or religious attachment to the proposed project area are requested to contact HDOT. Other individuals and organizations with demonstrated legal, economic or historic preservation interest in the undertaking are asked to contact HDOT and share information you may have on historical and cultural sites that you may have knowledge of within the proposed APE. We welcome any information within 30 days of notice.
Interested participants are requested to contact Mr. Lawrence J. Dill via email at Lawrence.J.Dill@hawaii.gov, or by U.S. Postal Service to 1720 Haleukana Street, Lihue, HI, 96766. Please respond by September 22, 2021.
