Clearwater Program set to become a reality

Sanitation District No. 2 Board of Directors will consider certification of the final Environmental Impact Report (EIR) for the Clearwater Program and adoption of the Master Facilities Plan (MFP) on Wednesday, November 28, 2012, at 1:30 p.m. at the Sanitation Districts of Los Angeles County Board Room, 1955 Workman Mill Road, Whittier, California.

This program’s purpose is to build a new outflow pipe to move treated wastewater from the Sanitation Districts’ plant in Carson to the ocean. The Sanitation Districts’ preferred site to construct this tunnel is Royal Palms Beach, just west of the White Point Landslide. Other alternative construction sites are Terminal Island and Angels Gate Park

Since the landslide occurred on November 20, 2011, there has been an updated traffic study and the proposed route for construction traffic would be 110 freeway to Gaffey Street to 9th Street to Western Avenue to Paseo del Mar. Construction would begin in 2016. The peak of construction is expected to occur in 2020.

You can view the EIR Appendices, published November 2012, on the Clearwater EIR page.

The Coastal San Pedro Neighborhood Council endorsed Alternative 4, the Royal Palms site, on March 19, 2012. The Northwest San Pedro Neighborhood Council opposed Alternative 4 due to the proximity to the White Point Landslide and to the earthquake fault, which in 1933 caused the closure of the White Point/Royal Palms thermal pools.

The NWSPNC has opposed alternative 4 and recommend alternative 1

Meeting discusses landslide causes and remedies

It was a packed house at the landslide meeting last night at White Point Elementary School to hear the results of the geotechnical report by Shannon & Wilson. City Engineer Gary Lee Moore presented the findings and long-term options.

Cause of Landslide

Nothing was found to definitively cause the landslide but several factors may have contributed to the landslide: irrigation, long-term coastal bluff erosion, precipitation, residential development, road construction, and underground utilities. The one factor that was found to not have any impact on the landslide was the Nike missile facility.

Land Movement & Water Levels
There has been no significant (> 1/10″) land movement at the monitoring sites. Ground water levels have increased by 15′ on the west side of the landslide. On the east side near residences, the ground water level has actually decreased by 1′.

Immediate Repairs
Immediate repairs will consist of grading the edge of the landslide to make it more stable. Dirt from the grading will be placed in the deepest crevices of the slide to even out the bottom. This will provide adequate surface drainage to convey water during the rainy season away from impacted areas.

A 170′ buffer zone around the slide will enable the construction of two U-turn areas. Earth anchors need to be placed into the slide area to prevent further movement. Additional monitoring wells and drains will be installed. These immediate repairs will cost approximately $5–8 million.

Proposed immediate repairs include U-turns. Cul-de-sac design could be complete in two to three months. Click to view larger.

Six Long-Term Options

  1. Do not reconnect Paseo del Mar (less than $1 million)
  2. Reroute the roadway through White Point Nature Preserve. Gates at each end of WPNP would close the road at night. ($4–8 million)
  3. Graded roadway. This slide got a good laugh at the meeting as the road looked like a skateboard half pipe. ($4–8 million)
  4. Return road to original level with retaining wall ($22–27 million)
  5. Return road to original level with no retaining wall ($42–50 million)
  6. Construct a bridge ($57–62 million)

A rerouting of Paseo del Mar would include gates for closure of the road every evening. Click to view larger.

Councilman Joe Buscaino fielded written questions from residents at the meeting. Here are a few of the questions and answers:

Q: Why was the report not released prior to the meeting so residents could ask more informed questions?
A: Changes were being made to the report over the weekend and the city attorney needed to be consulted first.

Q: Will the WPNP restrooms be connected to sewer lines prior to the Home Tour fundraiser in October?
A: This is being made a priority item. A link to the county lines would be cost prohibitive at $600,000 so other options are being considered.

Q: Will the Army Corps of Engineers be involved?
A: Congresswoman Janice Hahn has requested funding from the Army Corps on June 18th. The City Department of Engineers will be scheduling a meeting along with congressional offices.

Q: What affect will the slide have on the proposed Clearwater Project at Royal Palms and visa versa?
A: The City Department of Engineers is unfamiliar with that project.

Q: What will the decision process entail?
A: The process will be subject to some type of environmental review but maybe not an EIR. After the funding, construction usually takes three to four years.

Several requests were made by residents to work on traffic calming measures on Alma, Patton and Hamilton streets. Fire Station 101 Chief Terrazas said the narrowness of Hamilton is a problem. When another station covers for Station 101, they inform them of the alternate routes to Paseo del Mar. Residents also asked for increased police patrols on nights and weekends.

The full 800-page report can be accessed online at the City’s Dept. of Engineering website.

Reminder: Meeting tonight regarding Clearwater sewage pipe construction.

The outlined area of Royal Palms is a potential sewage outflow construction site for a two year span.

Tonight will be a public hearing to receive comments on both the draft EIR and draft EIS of the Clearwater Program. This program’s purpose is to build a new outflow pipe to move treated wastewater from the Sanitation Districts’ plant in Carson to the ocean.

The recommended site to construct this tunnel is Royal Palms Beach. Other alternatives are Angels Gate Park (at Paseo del Mar and Gaffey Streets) and Terminal Island.

Clearwater EIR released. Upcoming meeting March 8.

The Draft Environmental Impact Report/Environmental Impact Statement (EIR/EIS) for the Clearwater Program has been released today. The extended public review period begins today and ends on April 10, 2012. In a nutshell, the Sanitation Districts of Los Angeles County wants to build a new onshore tunnel and ocean outfall so that the current tunnels can be inspected and repaired if necessary. Construction would begin in 2016.

There are four alternatives being considered.

  1. Port of Los Angeles (access shaft at the Trans Pacific Container Service Corporation [TraPac] site and working and/or exit shaft at the former Los Angeles Export Terminal [LAXT] site): 8 yrs construction, $1,360 million
  2. Port of Los Angeles (access shaft at TraPac; construction shaft at LAXT): 6.5 yrs construction, $980 million
  3. Angels Gate at Gaffey St. and Paseo del Mar: 6.5 yrs construction, $910 million
  4. Royal Palms Beach: 6.5 yrs construction, $550 million

The two options that would affect coastal San Pedro residents the most are options #3 and #4. These are also the least expensive options.

Alternative #3 Angels Gate

Alternative #3 at Angels Gate would have a 20′ noise barrier. During construction of the shaft, approximately 10 to 40 trucks per day would be required for delivery of supplies and removal of excavated material. Shaft construction would take about 8 to 9 months.

Alternative #4 Royal Palms

Alternative #4, the Royal Palms option, is the recommended alternative. It would consist of an average of 10 trucks per day (about 40 trucks per day maximum) for 6–9 months during the shaft construction. There would be approximately 5 to 10 construction workers on site for a 10-hour shift per day, 5 days per week, for approximately 2 years to construct the exit shaft, manifold, valves, and piping interconnections. Demobilization of the site would take about 3 months.

Air quality would be significantly impacted during construction. Alternatives 1, 3, and 4 would exceed thresholds for volatile organic compounds (VOC) and nitrogen oxides (NOX), and Alternative 2 would exceed thresholds for VOC, carbon monoxide (CO), and NOX.

You can read the Draft EIR/EIS in its entirety on the Clearwater Program website.
