The Clearwater Program is Back
This will be a post that will be published on several of my blogs because I feel it is important enough to share with everyone.
The Los Angeles County Sanitation District Number 5 is continuing necessary and recommended processes to create a third Joint Outfall System (JOS) from its Carson, CA treatment plant to the Pacific Ocean.
Two Joint Outfall Systems (JOS), one built in 1938 and the other one built in 1958 currently provide outfall capacity between the treatment plant and outflow facilities near the Palos Verdes Shelf, offshore from Royal Palms, in San Pedro, Ca.
The capacity of the two systems is nearing full capacity and they will not be able to handle future capacity.
I have written what I feel is a fair amount about the Clearwater Program in past posts, but new information, information I need to correct, and new opinions can now be shared.
www.ClearwaterProgram.org has been bookmarked on my computers for several years and it is the first and best source of information I urge everyone to go to.
Last Monday I met with Mr. Glenn Acosta, P.E. and Ms. Leslie Winner, both representing the Sanitation Districts of Los Angeles County.
A new series of outreach meetings with individuals and groups is currently underway and I hope these two fine representatives meet with everyone who has any interest in the Clearwater Program and who are able to help with opinions and other observations concerning the new proposals for this very needed program.
Mr. Acosta's Email address is: email@example.com
With a whole new set of proposals and a new brochure available to offer greater insight into the Clearwater Program, concerned residents and others now can view new facts and opportunities that are different than what I wrote about previously.
What is not offered in the new proposals is four 'Alignment' prospects instead of over 16 first illustrated in previous information and the 50 originally offered by the Sanitation Districts.
Living doors away from the surface of Western Avenue and its subsurface containing the two original Outfall Systems, I may have a somewhat different perspective about the Program and I certainly have opinions, lots of them.
One of the first things I must offer is some corrections to some of my earlier posts.
According to the new information, the Outfall System Shafts would be approximately 30 feet in diameter and not the 'up to 200 feet' I originally wrote about. I know I heard that figure somewhere in earlier talks, but 30 feet is quite different that 'up to 200 feet', isn't it.
When I wrote that the depths of a shaft could be up to '500 feet' deep, I only got that incorrect by about 100 feet. According to the newest information, a shaft could be up to 400 feet in depth, the depths of any shaft could be much less than that.
I am also very relieved to note that there are only four remaining shaft site prospects with the new information.
As originally conjectured, there will be one shaft sunk at the Carson treatment plant's property. This will allow for one tunneling machine being places and would be one access point for the removal of dirt and debris while the tunneling is being done and the casements are being placed.
Originally, the public was informed about 16 sites between Carson and the Pacific Ocean where a second shaft might be considered.
Thankfully, very thankfully, that number has dropped to just four.
Of course and naturally, the old LAXT site is part of 'Alignment 1' proposal for a shaft that could include worker access and debris removal, all the way up to the placement of a second tunneling machine.
'Alignment 1', as currently proposed, would be the longest and costliest (on paper now) of the four alignments now under preview and review. Using this alignment would provide the Diffuser site somewhat close to the San Pedro Shelf, which is not as deep as the depth of the Palos Verdes Shelf provides.
'Alignment 2' is quite new and it probably includes a shaft at LAXT's old site on Terminal Island, it also adds another shaft at the former Southwest Marine site on Terminal Island. This alignment would be the second longest and it would provide the outfall from the plant going close to the Palos Verdes Shelf.
'Alignment 3' is considered by me right now as a 'non starter' because even though it provides an outfall end close to where 'Alignment 2' would have for its outfall, it requires a shaft be placed at the parking lot below the Korean Bell, on the Angel's Gate site. I will have more about that in a future post.
'Alignment 4' is the shortest and illustrated as being the 'least costly'. It would have the tunnel travel under San Pedro, as 'Alignment 2' also includes, but it's outfall would be near where the two existing outfalls are, near the Palos Verdes Shelf.
This alignment requires an Outfall Shaft being sunk at Royal Palms, down near the water.
I will have more about that in a future post.
I fully support the Sanitation Districts' Clearwater Program as long as the old LAXT site is utilized, no matter that is would be the most or second most expensive alignments to build.
What is most important right now, I feel, is community members for every community possible and reasonable, coming forward to offer facts, comments and opinions about this program that is truly needed for every one's future.
Please learn all you can about the Clearwater Program so you will have the best knowledge possible when dealing with a process that has already taken years and will probably take another 8-10 years to build out.
With all the opportunities, there are genuine concerns about the environment, both ecologically and when dealing with persons' environments.
