What a wastewater

Filed under: Alameda, Alameda Point, Development — Lauren Do @ 6:01 am

Continuing along the “how bad is the infrastructure at Alameda Point” road, next I tackle wastewater, aka the gross stuff that you want to leave your building.

Here is the current state of the wastewater system at Alameda Point from the Master Infrastructure Plan (MIP):

The Navy began the installation of this system approximately 70 years ago. The system is currently functional, however, the system is beyond its service life and has numerous deficiencies. Most notably, the majority of the system has deteriorated due to the age of the system and differential settlement has occurred over time at the Project Site. These effects of time have resulted in groundwater infiltration entering the on-site collection system and downstream transmission system. Additionally, portions of the existing system have adverse slopes causing wastewater build-up and stagnant conditions. There are portions of the collection pipelines that are located under existing buildings and outside of the existing and proposed backbone street rights of ways. The existing wastewater collection system does not meet the City’s standards.

From the Executive Summary:

The sanitary sewer system allows infiltration and inflow into the downstream transmission system during wet weather conditions.

Here’s how the MIP proposed to replace the system:

The proposed collection system will include gravity pipelines, ranging in size from 8-inch to 24-inch in diameter, and 5 lift stations. The proposed system will connect to the existing Pump Station R located at the Main Gate. The existing wastewater system, pipelines and pump / lift stations, within the Development Areas will be replaced in phases consistent with the development build-out. The proposed wastewater collection facilities will be installed within all backbone streets within the Development Areas.

The proposed on-site wastewater collection system will be owned and operated by the City of Alameda. The system shall be designed and constructed consistent with the City of Alameda’s Standard Specifications and Design Criteria. All lift stations will include redundant pumps, alarm systems and emergency backup power supplies to ensure no disruption of service. The proposed wastewater collection system shall efficiently collect and convey the wastewater such that the amount of lift stations required is minimized. The gravity pipelines will be designed to accommodate settlement at locations where long term differential settlement is anticipated.

Much like the potable water system, the reuse areas will be incrementally replaced as fund becomes available since there won’t be a large scale developer available to pay for the infrastructure out of pocket.

And the cost:

Phase 1 $11,993,000
Phase 2 $3,186,000
Phase 3 $3,677,000
Total   $18,856,000

  1. West Redline – from the north gate, past the gym, to the federal (VA) property – is the one street where infrastructure won’t be waiting for a developer to replace – unless we consider the VA a developer. Part of the deal that the city struck with the VA is that the VA will construct an entirely new street entrance at the north gate entrance, and install oversized pipes under West Redline that the city can (and will be allowed to) use for whatever, including the BEQ rehab and Sports Complex.

    Personal opinion: City should be zeroing in on a funding plan to tap into this new West Redline infrastructure to replace Monarch Street infrastructure. Monarch Street ends at West Redline. Monarch – so-called Spirits Alley – is where beverage companies are counting on reliable service (and where some of them may one day pay a lot of money to purchase their property). And replacing the underground utility system on Monarch does not require that the street above look manicured when the underground work is completed. The street pavement, sidewalks, lighting and landscaping upgrades can come later.

    I have a very clear recollection of a seating council Member “Mr Doug De Haan ” which you never miss a chance to make a good laugh from….” Asking this very same question , this was many moon ago before Bayport was even on the books , who was more qualified than Him , He was quickly shut down , they promised to lay new infrastructure and the like , they also promised the bleu print would be property of the City whether or not they would be retained as developer , they recognized the entire system had to be redone to meet new Federal regulations .fact is no one can dig on the point , if my memory is right they even talk injecting a slurry of concrete in it to seal off every thing.
    Here we are with the exact same problem decade later , projection cost $400 to $600 millions , Please take in consideration the very fact we as a City will be able to generate and will pass these cost to any business could they bear the cost and survive , unless they are your typical nation wide strip mall combined with outlet store , the truth is no.
    Pollution at the point , no one is allowed to dig more than few inches by fear of breaking what they call the crust , which seal all the chemicals dumped by the navy , when they could no longer dump it at the base they simply loaded in barrels and dumped offshore at the national sea reserve the Farralon .
    Try to dig a garden , make certain you do it in the middle of the night …..
    Doug De Haan was and has been ridiculed for standing up , He was right on , Sadly .
    The Navy is liable for clean up , however having accepted the land we are assuming everything that goes with it , very much like when you buy a house , you assume all work been done , my Vietnamien ” Great Family and Neighbor” are still paying for it as the City mandated them to retrofit the house to 2012 code , on a house built in 1906 , nothing different for the base .
    Sorry for the long post and lousy English “that’s for the spelling brigade”

  3. Some of the pictures of the worst flooding on the island were taken at Alameda Point today.

  4. Where are the pictures? The main gate area used to always flood during heavy rains…I don’t know if it still dous.

  5. I’m seeing them on FB. Don’t know how to move them here. Maybe you can go there? There are also pictures of lagoon docks inundated, streets in front of school now wading pool, fallen trees etc. True not as violent as past storms, so far, but steady heavy rain brings it’s own kind of flooding and damage. It’s about time for the trees and hills to start moving. I’ve heard people pooh, poohing the wimpy ness of the city, but I think the present much maligned city council, manager, fire, police and mostly public works deserve a big thank you for getting out the word and being there before and in the rain filling and carrying sand bags, cleaning drains, taking out private fallen trees, etc., etc.

  6. So, is the weather to harsh for our little cupcakes to go to school Friday too?

  7. Jack, I think it’s as much about their parents ferrying them to school. This storm does not seem to be as epic as predicted, at least around here, but the number of inches of rainfall in parts of the state to the north must break some records.

    In the 1980s when I lived across the estuary a friend and I stood at the edge of the estuary at Clinton basin leaning several inches ( like 6?) into the wind almost like those base jumpers in their flying squirrel suits. In 1983 we also had a king tide with rain storm which brought a foot of estuary water up the entire street on the last block of Fifth Avenue. Somewhere I have a picture of my landlord and I canoeing up the block. My shop was below street grade and had even deeper water. The winds with the storm today have not been anywhere as dire as expected.

  8. What a weak and useless group we and our society have become. This rain storm brings us rain and wind of what was considered normal for residents of the Bay Area over many of the last 50 years and longer.

    Our crazy incessant weather media blitzes have turned our youth and younger adults into absolute imbeciles. In past decades we always knew when it rained in the fall or winter here in the east bay we must be ready for downed trees, mud slides and flooding. Now we close our schools and frighten our populations to not venture out to experience the magic of a major storm.

    Today in the morning It was a magnificent out in the city of Alameda experiencing the water wind and rain. Of course one needs to be properly prepped and dressed….and use care and good risk judgements in this process. But certainly much more exciting and life giving than watching all the weather casters mostly nonsensical talking head reports.

    Tides were not a problem here only + 6 feet. Today. The King tides on 21, 22 December are only going to be +7 foot. It takes a king tide of +8 foot with strong southerly and large runoff from the delta and local streams to create interesting problems here in Alameda. Then it really gets interesting!

    Hope some of you and your kids, and, grand kids ventured out to the real world of inclement Wx today!!

  9. Some members of our community and two incoming public officials seem to think we do note need to replace the aging infrastructure at AP and we can just leave it as it is. As this post and Marie Gilmore’s op-ed in the Mercury News (http://www.mercurynews.com/ci_27111291/my-word-time-island-get-real-about-alameda) remind us, Alameda Point will need much of the $600 million of new infrastructure–whether or not opponents of redevelopment have their way in upcoming City Council decisions on the future of AP.

    I hope the recent election victors remember that their margins of victory reflect a 50/50 split in the community on these issues.

  10. I loved the scenes of Lake Petaluma and surfing Lake Tahoe. I was wondering: who goes to Lake Tahoe in December and has the presence of mind to bring a surfboard? Or are there surf shops at Lake Tahoe now?

    This is actually the first direct answer to a question I posted about VA and infrastructure several days ago. The document I scanned mentioned EBMUD won’t take responsibility for current pipes. The VA will need supply lines and electricity. Anybody know if there a similar deal for that infrastructure as well?
