Skagway River Levee Rehabilitation of Damaged Flood Control Works, Skagway, Alaska

Description

Repair the Skagway River Levee to restore its functionality to the pre-disaster conditions it has sustained as a result of significant flooding events. The levee is located along the southeast bank of the Skagway River starting at the Klondike Highway Bridge in Skagway and was constructed between 1939-1940 with its original length being 6,700 feet. All but a roughly 1,300-foot portion of the levee was modified by DOT and PF in 2001, encapsulating the original levee and adding Class III and IV armor stone along the riverward side slopes. The levee protects public infrastructure as well as residential, commercial, and historical properties. Damage to the levee includes loss of riverward armor stone and at least 300 feet of toe width reduction or loss. The aim of this project is to rebuild the levee toe and damaged slope along the DOT and PF portion of the levee with Class IV riprap and a 1.5 horizontal (H) to 1 vertical (V) side slope. The construction length is approximately 5,000 linear feet (LF). The type of contract shall be firm-fixed price. Construction wage rates (formerly Davis-Bacon Act wage rates) shall apply.
