Crescent City Harbor

 


CRESCENT CITY HARBOR
OPERATIONS AND MAINTENANCE


The San Francisco District is working with the Crescent City Harbor District to complete a Dredged Material Management Plan in an effort to plan for the next 20 years of placement for dredged material in the harbor.

INVESTIGATIONS

PROJECT LOCATION AND DESCRIPTION
 

Crescent City Harbor is located on the northern coast of California, approximately 350 miles north of San Francisco. The Harbor is a shallow draft, critical harbor of refuge that supports a Coast Guard search-and-rescue station, commercial and sport fishing, and recreational boating. The Operations and Maintenance (O&M) schedule provides for annual inspection and periodic repair of the Outer and Inner Breakwaters, as well as a five-year cycle for maintenance dredging of the Entrance Channel to a depth of -20 feet Mean Lower Low Water (MLLW), and the Inner Harbor Basin and Marina Access Channels to a depth of -15 feet MLLW. The Entrance Channel and Inner Harbor Channel were last dredged in FY19. The Marina Access Channel was last dredged in FY20.

FY 20 AND FY 21 ACCOMPLISHEMENTS (based on the availability of funds)

  • Funds were used for the annual inspection of breakwater structures, Geospatial Land Data Migration into the CorpsMap system (as mandated 23 Dec 2013 CECW-ZA), and maintenance dredging of the Entrance Channel, Inner Harbor Basin, and Marina Access Channel to restore them to authorized dimensions (Entrance Channel to -20 ' MLLW and the Inner Harbor Basin and Marina Access Channels to -15' MLLW). Cyclical maintenance dredging included Sediment Testing, preparation of Plans & Specs, Environmental Coordination, and Contract Procurement.
  • Dredge Material Management Plan progress included regulatory agency outreach, conducting a Public Hearing, Tribal outreach, analysis of placement site options, and Hydro-Dynamic Wave Modeling to research and recommend a base plan for dredge material placement over the next 20 years.

ISSUES AND OTHER INFORMATION

  • The Crescent City Harbor District is the Non-Federal Sponsor (NFS).
  • The NFS is to maintain the adjacent upland disposal pond for local marina maintenance dredging material, and the Corps may use it for Marina Access Channel maintenance dredging material (Project Cooperation Agreement 27 June 2000). The site is currently filled to capacity.
  • The Selected NED Plan for Operation and Maintenance of the Federal Channel was a nearby ocean site and Whaler Island for qualifying sand material. However, the nearest ocean site, SF-1, has been decommissioned.
  • There is a lack of nearby ocean sites and significant environmental coordination is needed to find and establish any new upland site.
