USACE has split more than 1,330 feet of Oswego Harbor breakwater repairs into three phases. A USD 9.1 million Outer West package is already under way. The new USD 14.9 million Dean Marine award covers 425 feet of East Arrowhead and another 307 feet of Outer West, with a third funded phase planned to start in 2027.

Published scope and current milestone

The 11 May 2026 USACE release identifies the current award, contractor, repair lengths, three-phase sequence and planned construction window. The August 2025 and April 2025 records describe the separate first phase and completed West Arrowhead work. The 14 August 2026 USACE and Port Authority account supports the cargo and navigation-access context only; it contains no phase-two mobilisation, installed quantity, inspection, acceptance or measured service result. The photograph shows stone handling during Oswego repairs in October 2024 and is not proof of activity under the 2026 award.

Coastal delivery and performance implications

The new award does not replace or complete the earlier package. Each phase has its own contractor, limits and close-out date, while all three share the navigation-channel interface. The Port Authority now ties that interface to aluminum, agricultural commodities and project cargo, but it publishes no service restriction or throughput series. Treating Oswego as one generic breakwater job would obscure both the work limits and the operating evidence still missing.

Evidence conclusion

Geometry, acceptance and performance evidence

The April award is a committed package, not field progress. Phase two should remain at award until Dean Marine is shown mobilising on the stated work limits; later reporting can then follow stone placement, surveyed or inspected reach and acceptance by section. The 14 August partnership account establishes why the channel and breakwaters matter to port access, not their current structural condition or the status of either contract. The completed 2,700-foot West Arrowhead repair remains separate delivery history outside the current 1,330-plus-foot programme.

Outstanding evidence

  • Dean Marine mobilisation and marine-plant setup
  • Stone deliveries and placement on East Arrowhead
  • Stone deliveries and placement on Outer West
  • Navigation controls around contractor equipment
  • Acceptance of the 600-foot phase-one reach
  • Phase-two acceptance against its two stated work limits
  • Phase-three contract and construction start
