Work continues uphill - 08-05-23
There is nothing new to write from CalTrans. Their update this week was the same as last week. They are working on the uphill side of the slide in preparation of the second retaining wall.
The soothing sight of traffic on CA-84
In a significant development, State Route 84 near Woodside, San Mateo County, partially reopened to one-way traffic control on July 27, 2023, following months of closure due to a damaging slide. The slide, which occurred on March 9, 2023, caused extensive harm to approximately 250 feet of the roadway, forcing authorities to take prompt action for repairs.
The California Department of Transportation (Caltrans) has been at the forefront of this challenging repair project, working tirelessly to restore the crucial thoroughfare. Despite the substantial progress made, caution is paramount, as the area remains an active construction zone. Motorists are urged to exercise vigilance while driving through the repair site as crews continue their work behind protective road barriers.
The scope of work required for damage repair is extensive and encompasses several crucial tasks. These include the repair of the slope and the construction of a retaining wall, the reconstruction of the roadway's structural section, erosion control measures, and the repair of the drainage system.
Looking ahead, the project team has outlined their upcoming activities to ensure the stability and durability of the repaired section. This includes efforts towards permanent stabilization of the uphill slope, completion of the lower slope wall, drilling and placing upper slope drains, installing new drainage across the east end of the project, and implementing culvert and vegetation control along SR-84.
Regular construction updates will continue through October, indicating the commitment of the authorities to keep the public informed about the progress of this vital infrastructure project. The ultimate goal is to fully reopen State Route 84 to all traffic by October 2023, providing relief to the communities and commuters who rely on this essential route.

Hello!
Sorry for the delay in getting these out. It’s been a busy couple of weeks!
Please see the video observations below and a new Orthomosaic & 3D model. The most remarkable change since I sent out the last update is the progress on building a rock retaining wall at the bottom of the slide. You should be able to see it in both videos and the 3D model.

05-28-2023 - I-beams!!!
There are a TON of I-beams on the slide site, and a lot of excavation has been done in preparation for the next phase of work. It is very encouraging to see the materials staged on site. Do consider supporting us on Patreon, and subscribing to the Youtube channel to get the updates as they happen.
Sunday, May 21st
Not much has changed since Thursday’s flight. There has been escalation of some of the slide. Per CalTrans, there should be one way traffic by July.
Activity at CA-Slide
Today I conducted a flight to observe the state of work considering the public meeting tomorrow.
The new drainage had been finished, with concrete poured
Excavation of the hillside has started
The Community meeting will be at Woodside Town Hall, but you can attend virtually:

Progress is slow but steady
On Saturday, May 13th, vegetation management and drainage tending were observed on road areas not in the closed section. Even a section of the hillside was removed that had slowly encroached onto the roadway.
In the slide area, a lot of progress was observed on a runoff management system west of the slide. I’m not a Civil engineer, but if I were to guess, this will help prevent future slides but potentially help stabilize the current one.
An explanation would be great
Sunday’s flight was sponsored by our first Patreon Anonymous Annie! You too could have a sponsored flight named after you, but there are only three more flights to name! Sign up quickly!
Sunday, there was plenty of activity observed: New fencing, dirt had been moved, a trench had been dug…
However, this is where communication from CalTrans would be great: If they prioritized getting one lane of traffic open, why trench across the entire road?
Also, there is a current theory on the mountain that the Wunderlich Park Forest Health & Fuel Reduction Project might have contributed to this project, as one of the areas cleared is directly above the slide. Additionally, according to the San Mateo County Parks own map, a Class II Stream is running directly from the treatment area above CA-84 to the point that the slide occurred…
A CPRA request has been submitted on behalf of everyone. When we get a response, a summary will be made available on this website. I admit I am not a Civil Engineer, but without clear and consistent communication, one can only draw the inevitable conclusion that CalTrans is NOT prioritizing one-lane traffic as they cut across the entirety of the roadway.
Working on a Saturday!!!
To the credit of CalTrans they are trimming trees on CA-84 and clearing shoulder areas! They are starting at the bottom with clearing shoulders, and trimming trees between Skywood Acres and Grandview.

Shoulder clearing on CA-84
It also appears the sink hole on CA-35 at Windy Hill was repaired, and the road is reopened to 2 way traffic!
Some progress, but not much
Apologies in my tardiness of getting last weeks updates out. This past weekend, and the weekend prior, show similar progress. Machines have moved, and on the 23rd of April it was observed that the surface of the road had been scrapped away. However, on the 29th of April, it looked fairly similar. So, a little progress, but not much else.
