Sinkhole Repairs Expedited: Goal of Christmas Day Completion

Update: City of Lafayette has contract with C.C. Myers Inc. for $600,000, which includes round-the-clock work.

Updated: 6 p.m. Tuesday, more details about the project.

The city of Lafayette has moved to an expedited, round-the-clock work schedule on the Dec. 2 sinkhole collapse that seeks to have Mountain View Drive restored over Lafayette Creek by Christmas Day.

The city has signed a "time and materials" contract for $600,000 for the expedited work with C.C. Myers Inc., "California's leader in emergency response," in the words of Lafayette City Manager Steve Falk.

Falk said he had presented to the City Council last week a scenario in which repairs would go on into the spring before the drive was restored. "The City Council was not satisfied with that answer," Falk said. The city began pursuing an expedited solution with C.C. Myers Inc., based in Rancho Cordova, which worked on infrastructure repairs in Northridge after the 1994 earthquake and to the MacArthur Maze in Oakland after the tanker truck accident in 2007.

The $600,000 figure was negotiated, Falk said, and pertains to the "scope of the work as we understand it." Falk added that the work may not be finished by Christmas if the weather is exceptionally wet in the next two weeks.

There is now Visqueen plastic lining the creek at the sinkhole chasm to keep the banks from eroding, Falk said. A temporary dam is built on the creek with pumps that can send water through pipes downstream to bypass the chasm that cuts Mountain View Drive in two.

The permanent fix is move 10 concrete pipes, 12 feet in diameter, to form a high-capacity culvert, said Mark Beadleston, general superintendent for C.C. Myers Inc. Those pipes come in 8-foot sections that weigh 42,000 pounds each. Cranes had begun to move the pipe sections in place on Tuesday.

One local resident remains inconvenienced by the emergency work, Falk said. That is the family of Mike Anderson, elected as mayor of Lafayette by the City Council Monday night, —whose access to their driveway is blocked.

The city has circulated fliers in the neighborhood explaining the plans for the expedited repair.

Having worked as a civil engineering designer and land surveyor, I think that cost is a little excessive. I realize the culvert, utilities and street need to be replaced but we are talking about what 24' wide portion that is about 20' in length and the water has already demolished most everything. Unless there's going to be a bunch of remediation in the creek. Even then, well......................................

And how many people does this really affect? On a per household basis, what is the value of this repair? Are we all to rest assured that any such future problems affecting our own streets in Lafayette will be fixed so speedily and with a comparable budget?

In a time and materials contract, the contractor's labor and equipment are paid for on an hourly basis and all materials used are paid for by invoice. Rates are union scale and the same regardless of who the contractor is. This permits the City of Lafayette to better control the scope and the cost an emergency repair effort like this one.

Is it possible this was not sent out for bids? I thought that was a requirement. Leaving it would really affect no one. I think the property would increase in value if just a foot bridge was added and the creek naturalized. This is a dead end street that at the moment is 2 dead end streets separated by the creek, it is a pretty creek at that point. Those on the up side just have a one block change to their drives home. Councilman Mike Anderson was affected, joked about walking an extra 1/2 block to get to town last night during the council meeting! Yes, your road will get a speedy fix from the fastest 24 hr/day contractor in the state, IF you have a councilman for a neighbor.

One household inconvenienced? Are you kidding me!? As someone whose driveway is 15 feet from the sinkhole, I can say with certainty that more than one household is effected. For the past 10 days, we, the residents on Mtn View have endured power generated flood lights, bulldozers, construction crews, and periodic interruption of our utilities (not to mention last week's surge of news vans blocking access to our driveways). While I appreciate the push to complete the work in 2 weeks (especially if any our neighbors are at risk of worsening property damage), it is daunting to think that we will have to endure the noise and bright lights for 24 hours a day for the next 2 weeks. If this doesn't sound too bad, then I would encourage anyone to go and hang out with a highway construction crew to get an idea of the noise. It has been challenging but do-able to have construction crews working 12-15 hours a day. I can't imagine what the next 2 weeks hold for me, my neighbors, or our 4 month old baby who continues to wake throughout the night because of the bulldozers and CATs outside. I, for one, would prefer this job take a couple of weeks longer if we could get 8-10 hours of respite from the noise at night.

William, I am aware of the meaning of "time and materials" having written countless scope and cost documents myself. It's the amount of $600,000 as an opening that concerns me. That and the fact that it IS a T & M contract (as opposed to a "Lump Sum" contract) that allows any overage to be added to that opening amount. Not having seen any plans, I can't speculate accurately but looking at the damage first hand, either they're going to do more than fix the existing damage or maybe they're over-engineering it for any future problems. Do you work for the city or are you a resident?

Ms. Bronson-Castain, Having worked 20 plus years around that kind of envronment, you have my sympathies. Between the holidays and your newborn, I can't imagine what it must be like to deal with the noise alone, not to mention the cars, semi-invasion of privacy etc. I really hope they do have it fixed ASAP.

Mountain View is a dead end Street? What town do you live in?? There are hundreds of residents that need that road. And it's a major part of the downtown traffic bypass.

Not since the Germans went with hydrogen instead of helium have I read such nonsense. Revolve the work around your baby's sleep schedule....

Agreed, this is like killing a fly with a hammer. An extremely expensive hammer. Unrelenting noise and sleep deprivation can affect your health and that of your newborn. Talk to your Mayor about the city footing the bill for the only hotel in town. I suspect they are waiting for these requests. This was not a natural disaster, rain was forecast and it rained! Lafayette is currently dealing with a "A Notice of Violation" from SFBRWQB (water quality) for illegal dumping by the Parks Department and accumulation of trash in Las Trampas Creek. Different creek, same issue. The public works department did not do the job we pay them to do: keep the waterway free of debris, the creek waters clean, and maintain the integrity of the roadways. An ounce of prevention would have prevented this failure.

Sorry, the one household comment came from the reporter on KCBS, who went on to say it was the mayor who cannot use his driveway.

Is mapquest wrong again? It shows Mt View dead ends at the top of the hill. Have there been traffic jams on Dewing? I drive all over town and have not noticed any change in the flow of traffic. My real point was to take some time to figure out the best solution, not just the knee jerk, put Humpty back together again as fast as possible. The way it was didn't really work out that well, so can we improve it? However, the time has passed for that line of thought. The creek will soon again be out of sight, channeled into an unnatural pathway and traffic will flow on Mountain View.
Born and Raised December 12, 2012 at 10:54 PM
Joe, just out of curiousity, what town do you live in? It can't be Lafayette with a statement like that. Mountain View is definitely NOT a major bypass street. Even if you did consider it that you could go another block down to Dewing and use it as a bypass.
