The U.S. Army Corps of Engineers, District of Los Angeles, along with contractor Manson Construction, will begin “mobilization” today, April 11, 2022, for the annual dredging of the city of Oceanside’s port entrance.
“Lot 12 will be fenced, fire rings will be removed, a portion of the river bed will be fenced off and a marked trail will be established at Harbor Beach. The contractor will prepare the underground pipe under Harbor Beach for connection to the dredge pipe,” the City of Oceanside Harbor said in the update. “There will be significant heavy equipment movement at Harbor Beach. The dredger HR Morris will arrive on Tuesday April 19th.”
According to the city, the entire dredging cycle is expected to take 6 to 8 weeks and be completed no later than Memorial Day weekend.
The average amount of sand dredged from the bay and placed on the seafront beaches ranges from 200,000 to 250,000 cubic meters.
The Oceanside Harbor Inlet is dredged annually by the Army Corps to ensure ships can safely enter and exit Oceanside Harbor and Camp Pendleton.
All year round, sand accumulates in the harbor entrance during storms and southerly swells. The accumulation of sand creates shallow depth in the inlet and breaking waves that can limit navigation.
Last year, Manson Construction removed over 300,000 cubic yards of sand from the inlet and dredged it to a depth of minus 30 feet. Most of the dredged sand was used to fill in the deep erosion caused by the winter storms.
