FY 22 accomplishments

  • Perform maintenance dredging of the Bar and Entrance Channels to the authorized project depths with the Government hopper dredge Essayons, and/or through a regional contract.
  • The Interior Channels are dredged with the Government hopper dredge Yaquina as funding permits.  In FY22 plant schedule constraints arising from the overall west coast program precluded dredging the interior channels. 
  • A contract to repair both the north and south jetties was awarded to S.E.A. Construction on April 22, 2020, in the amount of $22,103,000.  Construction of the north jetty got underway in the summer of 2020.  The contract was completed for about $30M in Oct. 2022.
  • Coordinating with the other West Coast Districts to schedule hopper dredging for this year’s episode.  A combination of Government Dredges Essayons and Yaquina and West Coast Hopper Contract will be utilized to complete the work.

FY  23 accomplishments

  • Perform maintenance dredging of the Bar and Entrance Channels to the authorized project depths with the Government hopper dredge Essayons, and/or through a regional contract.
  • Dredge the Interior Channels with the Government hopper dredge Yaquina as funding permits.  The FY23 Yaquina schedule is slated for about 14 days of dredging.  The schedule is contingent on successful annual dry dock repairs over the winter.
  • Repairs to the North and South Jetties were completed in Q1 FY23 and the contract is being closed out at a final cost of around $30M.
  • Coordinating with the other West Coast Districts to schedule hopper dredging for this year’s episode.  A combination of Government Dredges Essayons and Yaquina and West Coast Hopper Contract will be utilized to complete the work (ETA is 1-2 MAY 21)

ISSUES AND OTHER INFORMATION

  • The Humboldt Bay Harbor, Recreation and Conservation District is the Non-Federal Sponsor (NFS).
  • Continued management and monitoring of the offshore disposal site, HOODS.
  • Development of a regional Dredged Material Management Plan (DMMP) that will examine the feasibility of conducting a nearshore dredged material placement demonstration project by placing entrance channel sandy material in water adjacent to the eroding north spit area.  Participation with EPA to expand HOODS disposal site, and possible include a nearshore annex to the site for beneficial disposal of sandy material in the littoral cell.
  • Continued shoreline monitoring as a condition of continuing to dispose dredge material at HOODS.
  • Conduct comprehensive condition surveys of navigation structures to assess damages and prepare plans and estimates for needed repairs.
