• Discussion Points:

• Third Party Hydrographic/Land Survey is required in Port Orford, optional in

Chetco, Baker Bay and/or Chinook, USCG Cape Disappointment, Port of Longview Willow Grove Boat Basin, and Port of Longview Berths 1-9.

• Survey Constraints (Multi‐beam vs Single beam) & Vertical side slope in some areas. Floating docks.

- Several optional CLINs/work areas. Reasons for optional work: USCG Cape Disappointment, Port of Longview Willow Grove Boat Basin, and Port of Longview Berths 1-9 are optional because we are not certain about dredging need, if shoaling develops, it typically happens after the spring snowmelt flows. The Contract will likely be structured to allow for any combination of optional work area CLINs to be exercised.

• Specific requirements for Port of Longview Work Plan in the Environmental Protection Spec and Port of Longview Berth 1-9 Dredging underpier sloughing dredge passes and surveys in Dredging and Channel Clearing Spec.

• At the Longview Turning Basin and Port of Longview work areas, anticipate ships transiting and mooring at berths and dredge contractor will need to move as needed to accommodate commercial vessel operations.

• Anchorage dredging is a new authority from WRDA 2020 so this area of Lower Vancouver anchorage has not been dredged before. If the contractor provides a 7-day notice, the River Pilots will keep the anchorage dredge area clear of ships.

• Port of Longview Willow Grove Boat Basin is very shallow with constrained access. The boat launch will be closed to public use during dredging operations for a maximum of three days.

• There are existing submerged utilities at Oregon Slough. The acceptance area was cleared to required depth most recently in 2022. All known information about the utilities will be provided in the contract attachment.
