Landslide Update 01.20.12

Here’s an update from LA City Engineer Gary Lee. Also, LAFD went underground last week… Read below.

Here’s the inside scoop / summary of accessing underneath the Nike Missle site:

1st step – General meeting at the site with City agencies, including the Fire Department to discuss and formulate a plan. This was done on January 5, 2012.

2nd step – On Wednesday, January 18th, the Fire Department opened the doors to do a thorough inspection, and material sampling. This day was for Fire Department access only. No other persons were allowed to enter the site due to the uncertainties that present themselves, e.g., unsafe conditions, unsafe ventilation, dust, the potential for unknown hazardous materials, the presence of rattle snakes, spiders, scorpions, field rats, etc.

3rd step – Analyze material samples and test for hazardous substances, e.g., asbestos. This step should take about one week, which means the earliest for potential non-Fire Department persons, including City personnel is approximately the week of January 30th.

Landslide Update 01.11.12

Fellow residents -
Your PRA Board had a productive meeting last night, covering multiple key topics. Meanwhile, here’s a basic “official”  update from City of Los Angeles Public Affairs Dept. re: the Paseo landslide … Word has it that a visit to the tunnels beneath are next:
  • The geotechnical firm of Shannon & Wilson has concluded exploratory drilling operations at the Paseo Del Mar landslide site.
  • Collected soil samples and data is in the process of being analyzed to further determine the ongoing extent of the landslide.
  • Representatives of the Board of Public Works and Bureau Engineering conducted a routine site visit on Thursday January 5, 2012 to further assess area conditions.
  • The Bureau of Engineering will continue to post a monthly report on the status of the slide at the following website: http://eng.lacity.org/whitepoint/whitepointlandslide.htm
  • Public Affairs Office bullet points will continue bi-monthly as needed.
  • City of Los Angeles Recreation and Parks Department closed the walking trail thrOUGH the Nature Preserve during a rain event in December 2011.  The trail was inspected and re-opened immediately after the rain event.
  • Residents and visitors are urged to keep out of the closed-off area as it presents an immediate and life-threatening hazard.

Storm Drain and Beautification Update 12.15.11

The County Flood Control District will complete all work to divert the storm drains by tomorrow – Friday December 16.  As part of the county’s normal routines they will periodically conduct inspection of the drains.

The berms have been constructed and everything else is done.  The County is hydroseeding the slopes/bluff areas that were disturbed.  The seed mix was provided by the Conservancy so the vegetation will match what is in the Conservancy area once it matures.

East of Slide Update 12.10.11

Lawrence Cuaresma reports about land surveys east of the slide.  No more movement detected, as recently as the 7th.  This is good news for residents.

Notes from surveyor, Mark Santistevan:  There are three points that he monitors on the curb face fronting the house at 1481 W. Paseo Del Mar and three points in an area bounded by the intersection of Paseo Del Mar & Weymouth going west to where Paseo ends due to the landslide and going north to the chain link fence that parallels the Nature Preserve path.  All of these monitoring points have not moved and the last measurements were taken on Wednesday, December 7, 2011. 

Nature Preserve Update 12.09.11

  • The consultants for the City of Los Angeles (Shannon & Wilson Inc.) are installing 9 survey sites (inclinometers) at White Point to monitor the landslide. This will require accessing the sites with a rig spanning 6 feet in width. The digging will disturb an area approximately 10 feet in diameter per bore, with additional minimal disturbance in an additional 10 feet beyond this. Once the surveying equipment is installed, each hole will be covered at ground level, and will need to be accessed on foot about once a month. Work is expected to take 3 weeks to complete. They will be working on weekdays and Saturdays.
  • During rain events, Rec and Parks will be closing the southern trail which runs from the parking area to the Weymouth/Paseo del Mar entrance to the Preserve.  To maintain clear access, WPNP requested that detour signage be in place to direct people to the next closest entry/exit to the Preserve.
  • WPNP pursued the issue and received confirmation that the T-gate will be now closed nightly to the parking area of the Preserve.  Due to budget cuts, it was only being closed on average of every other night by the Office of Public Safety.  Thank you 15th District Council Office for your support in facilitating this!

Paseo Del Mar Landslide Update 12.01.11

Official City of LA provided Landslide Updates as of 12-1-2011

»  The City hired an outside geotechnical firm to conduct an independent
study to determine the ongoing extent of this landslide.

» Exploratory drilling began on November 25, 2011.

» Currently, drilling operations are in progress.

» The drilling process and data collection will continue for approximately
four weeks.

»  A preliminary report still is on schedule to be produced by January 6,
2012.

» Crews are on site and continue to monitor the slide daily.

» So far, still no evidence has been seen of the slide moving toward nearby
residences.

» The area remains an unsafe and dangerous area for the public to be near.

Recap of last week’s updates:

» Until that study is complete City officials cannot speculate on what
caused the initial landslide.

» The Bureau of Sanitation capped an 8-inch sewer line, and the
Department of Water and Power capped a small water line, and relocated
an overhead 34.5 kV power line.

» The City erected an 8-foot tall chain link fence around the slide
boundaries to keep people away from this unsafe area.

» Again, urging all residents and visitors to keep out of the closed-off area,
as it presents an immediate and life-threatening hazard.

Coastal NC Environment Committee Meeting on Saturday

There will be a meeting this Saturday, 12/3, at 10 a.m. in Point Fermin Park at the (Band Shell) of the Coastal NC Environment Committee to move forward with communication patterns and processes.

Paseo del Mar Landslide Update – Vincent Jones

The question was asked if placing a mesh, quick growing seeds or other temporary measures would reduce the risk of further slides at Paseo Del Mar.

Placing mesh and seeds are erosion control measures that are commonly used to minimize the impact of areas of superficial or shallow instability, such as mudslides.  These measures will have no benefit on a deep landslide of this magnitude.  As you know, measures that have been taken to control impacts on the landslide include: 1) the County of Los Angeles has rerouted the storm drains away from the landslide area, and 2) utilities such as sewer and water lines have been decommissioned.  In addition, the comprehensive geotechnical investigation of the landslide area should reveal information that will help to evaluate future erosion.  Now that we have begun drilling for exploratory data collection, this will help.

The back slope along the Nature Preserve, created by movement of the landslide, is near vertical.  This slope will erode back to a more stable angle.  This is a natural process, of potential erosion back into the Nature Preserve, and should not impact the existing residences.

Paseo Landslide Update – Storm Drains Ready

The Los Angeles County Flood Control District is responsible for providing flood protection on a regional basis.  The two storm drains that have been relocated provide regional flood protection to the west and east communities in the vicinity of the slide area.   The relocated storm drains are now fully functional and are ready for upcoming storms.
Regarding localized drainage concerns around the immediate slide area, this is something for the City to consider.  Please note that the landslide is still active and because of this it may be difficult and unsafe to try to install or construct any type of drainage system around this area.
As the County wraps up the final storm drain construction items in the next three weeks, they will see if constructing an asphalt berm on the street (like a speed bump) would minimize storm water from travelling to the slide area.  Placing sandbags to divert some storm water may be another option.

Paseo Del Mar Landslide 11.22.11

Neighbors -

As many of you may know, the slide has created a flurry of media attention – particularly following the incident on Sunday, which essentially created an island, with part of Paseo and the lone, symbolic Palm tree on it. Having been interviewed by multiple networks, I have tried to remain optimistic about the future of the slide, that is, it has “defined” itself further following this major, shocking incident and that it has provided a sense of relief.

These comments are not meant to be construed that any of this is over, as the ground / land will continue to move and there will be more sliding, crumbling, etc. Importantly, PRA will try to keep you updated on the extent of this – through the coordinated means of the Coastal Neighborhood Council, City and County reports. There are plenty of considerations and outcomes as to the cause of this tragedy, as the City’s new geo-tech consultant gets busy in their work.

I’m pleased with the progress we have made in organizing and making sure those that should take ownership, do, and be held accountable to the extent of the progress, via their designated roles and our taxpayer dollars, and those we can trust to carry the coastal soul forward.

Most of all – trust yourself in making the smart, right decisions and participating in this process that, while the initial slide may have happened “quickly”, no matter the reason, we’re in for a quite a process to restore our coastline and its access. As residents, let’s not be divided, let’s stay glued and tuned in.

Most of all, stay positive and hopeful in the spirit of local volunteerism collaborating with many, many levels of government. There is a lot at stake and I appreciate your participation in the PRA and the Coastal San Pedro Neighborhood Council to help foster positive outcomes for all of us.

Here’s a message from  Andrea Vona – Executive Director PVPLC / White Point Nature Preserve:

The landslide at Paseo del Mar has been the focus of our community energy and engagement for the past two months.  It is gratifying to see how we have come together with energy, engagement, organization and information sharing over the past two months during this difficult and stressful time.  I have had the pleasure of meeting many of you at recent community meetings.

Palos Verdes Peninsula Land Conservancy is proud to be part of this community.  We are coordinating with our project partner for the White Point Nature Preserve, the City of LA Department of Recreation and Parks and also the 15th District Council office, the Mayor’s office and the Department of Water and Power (DWP).

I wanted to update you briefly about a few topics with regard to the White Point Nature Preserve:

  • Sewer Connection- In late September the sewer line under Paseo del Mar was capped and the Preserve lost the sewer tie in for the restrooms in the Nature Education Center.  We are working with the Department of Rec and Parks to determine an appropriate new connection point.  Recreation and Parks has provided temporary restrooms on the site.
  • Power Poles-Nine power poles were installed through the middle of the Preserve in order to maintain power to the sanitation pump station on the corner of Paseo del Mar and Western.  At a coordination meeting we received a commitment from the DWP that the installation was temporary and that they would explore appropriate alternatives for the permanent routing of these poles once the slide had stabilized.
  • Chain Link Fence- Due to safety concerns about people entering the slide, the City of Los Angeles met on November 10th and decided to install chain link fencing along the southern trail in the Preserve that runs north of the most active slide area.  It has been confirmed by the City that this is a temporary fence and that the fence will be removed when it is once again safe for the public to enter that area.
  • Irrigation- Any concern about the use of landscaping irrigation is unfounded.  The only irrigation has been surface irrigation for limited periods to establish native drought tolerant habitat and small native plant demonstration gardens.  The native plant demonstration garden has been irrigated following the City of Los Angeles’ water conservation measures.
  • Mayor’s Office- To provide better access for concerned residents to stay informed about the slide, I requested that Mr. Ricardo Hong from the Mayor’s office meet with June Burlingame Smith, the President of the Coastal San Pedro Neighborhood Council.  June toured the slide area with Ricardo last week, to offer her a firsthand look and an opportunity for information exchange.  I also requested that a mayor’s representative attend the Coastal San Pedro Neighborhood Council meeting this evening, which they have confirmed.

With the closure and loss of a portion of the sidewalk on Paseo del Mar, many people are exploring White Point Nature Preserve for the first time.  We welcome you all and hope your experience through the Preserve is an enjoyable one.

The Conservancy is dedicated to maintaining access for the public to the Preserve throughout this evolving landslide and its aftermath. The Nature Center is open on Wednesdays, Saturdays and Sundays from 10am – 4pm.  The Ranger Walks are the second Saturday of each month from 10am – 12 noon (Free – provided by City of LA Dept. of Recreation & Parks).

We look forward to working creatively with the community for long term solutions to many of the temporary features that the Preserve has inherited due to this most unfortunate event.

We invite you to find out more about White Point and the Palos Verdes Peninsula Land Conservancy by visiting the Nature Center and our website at www.PVPLC.org. info@pvplc.org or call our office at 310-541-7613.
