The City of Whittier is preparing to begin Phase III of its harbor rebuild project, a major infrastructure upgrade designed to replace aging pilings, expand capacity, and improve long-term access to Prince William Sound.
According to federal documents filed this week, the project includes the removal of 165 pilings, including 155 creosote-treated timber piles and 10 steel piles, and the installation of 90 new steel piles. Crews will also install new floats and walkways to modernize moorage and improve safety and functionality.
Construction is expected to take place over 29 non-consecutive workdays within a six- to seven-month window starting in fall 2025. The rebuild is one of the most significant harbor infrastructure efforts in Whittier in recent years, aimed at replacing deteriorating infrastructure and meeting modern environmental standards.
To proceed with in-water work like pile driving, the City of Whittier has applied for an Incidental Harassment Authorization (IHA) from the National Marine Fisheries Service. The permit would allow for the unintentional, non-lethal disturbance of marine mammals such as killer whales, harbor seals, Steller sea lions, and Dall’s porpoises during construction.
As part of the regulatory process, federal officials are requiring several mitigation measures, including marine mammal monitoring, shutdown zones, and “soft-start” procedures to minimize disruption.
The NMFS has opened a public comment period through July 7, allowing residents and stakeholders to weigh in on the proposed authorization. Comments can be submitted via email or through the Federal Register website.
The rebuild comes as many Alaska port communities face challenges maintaining critical infrastructure amid aging facilities, higher construction costs, and stricter environmental guidelines. Whittier’s harbor serves as a key point of entry for freight, fishing vessels, and tourists accessing the sound.
If approved, Phase III will mark a significant step in upgrading the city’s waterfront and ensuring the harbor can meet commercial and recreational needs for decades to come.
