County of Monterey is Planning to have Repairs done on Arroyo Seco; Road Repairs are Expected to be Complete by the End of 2023
The County of Monterey is planning to begin repair work on Arroyo Seco Road in south Monterey County in
September of 2023 and hopes to have work completed by the end of the year.
Arroyo Seco Road suffered severe damage during storms in March.
Heavy rains and flooding undermined and washed out a section of
the roadway, creating a steep 40-foot vertical drop on one side and
compromised a travel lane for vehicles. The road has been closed to
the general public since that time, only local residents who live
along that portion of road are allowed access in and out of the area.
Staff within the County’s Public Works, Facilities and Parks
Department have completed a design and emergency repair plan for
the roadway and bids for the emergency repair are due on Friday,
September 1 .
Repairs to the road will take place in two locations and anticipated costs
for this work are approximately $6 million. Here are the locations and
work plans for each area:
• Project site #1 at milepost 2.5: Flooding here overwhelmed
existing culverts. Repairs include replacing damaged culverts with
new four 4-ft diameter pipes.
• Project site #2 at mile post 4.2: This is where a large section of the
roadway is settling and cracked the pavement. To reconstruct the
area and support the pavement, 22 steel-reinforced concrete piles
that are each 30” in diameter will be drilled into the area below the
pavement, creating a “stitch-pile row.” These concrete piles will
go to a depth of 30 feet below existing grade to support the
roadway.
The repair project has been designed to meet FEMA guidelines for disaster reimbursement. Advance funding
from the California Office of Emergency Services, (Cal EOS) is being used to assist with this project.
Once repair work is completed, it will allow for the reopening of Arroyo Seco Campground, which was
closed by the US Forest Service. Staff has been and will continue to coordinate with the US Forest Service.
