Dredging Operations

NOTICE OF EMERGENCY BEACH DISCHARGE ~ FEDERAL ENTRANCE CHANNEL

Dredging operations will be conducted on Friday, Saturday and Sunday, January 27, 28 and 29, 2017, to address shallow conditions in the entrance channel. As of Tuesday, January 24, 2017, disposal of material from the federal entrance channel is being conducted under the Emergency Beach Discharge provisions of the Santa Cruz Port District's permit with the Monterey Bay Air Resources District (Section C). Emergency operations are necessary to address safety of the federal navigation channel. High surf conditions have buried the offshore pipeline, leaving the Port District with no disposal alternative under the Discretionary Beach Discharge provisions of its permit with the Monterey Bay Air Resources District. Emergency discharge will continue until the offshore pipeline can be safely re-established and channel depths are restored. Emergency disposal operations curtail hydrogen sulfide emissions to a rolling one hour average of less than 30 ppb. All disposal will be through the onshore pipeline, on the beach or in the surf zone, until the offshore pipeline is re-established.

Learn why seasonal dredging of the Santa Cruz Harbor is necessary, how it is done, and its effect on the environment.

During dredging operations, pass Twin Lakes on the east side (Crow's Nest side) of the channel unless otherwise marked. Stay at least 50' from the dredge. Contact the crew for passing instructions on VHF channel 8.

North Harbor Dredging - October 6, 2016 - February 28, 2017

Dredging of the north harbor began on October 6, 2016, and will continue concurrently with entrance dredging operations. (Now that both dredges meet Air Toxic Control Measure Standards for diesel emissions, the Monterey Bay Unified Air Pollution Control District is processing an Administrative Modification to Squirt's Permit to Operate to eliminate the provision that does not allow concurrent operation of the District dredges). Inner-harbor areas to be dredged and the anticipated pipeline configuration are depicted on the attached Notice. Mariners are advised to be aware of pipe hazards in the north harbor. The pipe is black, sits at and just below the surface of the water, and is difficult to see. If your vessel is berthed in an area that may be impacted by the dredging operation and/or pipe, contact the crew on VHF channel 8 for navigating and passing instructions to assure safe passage..

Update as of 01/26/17: Due to severe storms and run-off from January 2017 storms, the inner-harbor's offshore disposal pipeline is currently buried by sand. Crews are working to re-establish the offshore pipeline and will resume dredging operations as soon as possible.

South (Inner) Harbor Dredging

The western bays of B, C and D docks are authorized for dredging this season to restore the areas to design depth of -8 feet MLLW (plus 2' overdepth allowance). The South (inner) Harbor dredging window extends through April 2017.

If you have a vessel in an area that may be impacted by inner-harbor dredging operations, be sure to read all gate notices and check the harbor's website for the latest schedule updates and information.
