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.
