USACE Buffalo awarded DMYLES a USD 11.7 million contract on 9 April 2026 for approximately 250,000 cubic yards from Cleveland Harbor's upper Cuyahoga River channel across two planned windows. Mobilisation, first-window production, measured quantity, placement split and completion are not confirmed.

Project anatomy

Contract scope and delivery roles

Client / authority
U.S. Army Corps of Engineers, Buffalo District
Delivery parties
DMYLES, Inc.
Contract route
USD 11.7 million federal maintenance dredging contract covering two execution windows
Execution window
15 May-30 June and 1 October-30 November 2026
Works package
Dredging of approximately 250,000 cubic yards from the upper Cuyahoga River section of Cleveland Harbor's federal navigation channel
Marine interfaces
Maintenance of 5.8 miles of federal Cuyahoga River channel plus one mile of Old River, annual upper-river shoaling, upland processing, beneficial use, confined disposal, and short- and long-term placement-capacity planning
Commercial evidence boundary
The award is specific and funded, but the delivery question is wider than dredging volume: two seasonal windows must pass through a live sediment-routing system while SPMF capacity is extended, nearshore alternatives remain under assessment, and CHEERS remains a future programme rather than current placement capacity.

DMYLES received the two-window maintenance award

USACE awarded DMYLES USD 11.7 million for approximately 250,000 cubic yards from the upper Cuyahoga River, with work planned for 15 May-30 June and 1 October-30 November. Award and planned dates do not establish mobilisation, production, placement, survey acceptance, or completion.

Source

USACE opened short-term placement scoping

The preliminary-assessment addendum evaluates limited open-water placement, CDF 12, the Port's SPMF, and littoral nourishment for future Cleveland material management. It is an alternatives and public-comment record, not a selected or authorised route for the 2026 DMYLES contract.

Source

The Port approved an SPMF capacity bridge through 2029

The Port board awarded a USD 4 million extension project to Mark Haynes Construction to keep the current repository usable until CHEERS is ready. The award establishes a capacity intervention, not completed construction or unlimited placement capacity.

Source

A separate prior-year DMYLES campaign was scheduled to start

USACE announced a USD 9 million 2025 contract for approximately 180,000 cubic yards from the lower Cuyahoga and CDF placement. USACE later reported 255,651 cubic yards removed in 2025; neither the earlier scope nor that result proves 2026 execution.

Source

The Port documented a split sediment route

The Port reported approximately 50,000 cubic yards hydraulically placed into the SPMF for processing and beneficial use and approximately 150,000 cubic yards routed to a silt basin. A separate 20,000-cubic-yard Cleveland-Cliffs dock campaign is excluded from the federal-channel total.

Source

USACE published the DMMP and EIS review plan

The review plan defines the technical and peer-review path for long-term dredged-material management. It is planning evidence and does not establish a final DMMP, approved CHEERS capacity, or a selected annual placement route.

Evidence gap

What remains unverified

Outstanding evidence

  • Measured completion of the May-June dredging window
  • October mobilisation, production, and 30 November completion
  • Final volume split between upland processing and confined disposal
  • Remaining confined-disposal and beneficial-use capacity
  • Post-dredge hydrography and published federal-channel availability
