Fremont Planning Commission to vote on Dumbarton Quarry’s conversion to park land

Here is the second of two Fremont stories in Wednesday’s print edition. This one on Dumbarton  Quarry’s planned conversion to a 91-acre park is the first of a number of stories we’re planning on proposed changes in this part of town.

FREMONT — The Planning Commission on Thursday will consider allowing a former quarry to be converted into a 91-acre regional park, but some environmentalists question whether the quarry company will deliver, given that its first plan to transform the site into a lake fell by the wayside.

Dumbarton Quarry Associates, a company that operated a crushed rock aggregate quarry at the Ardenwood neighborhood site, cut a deal with Fremont in 1996 that called for the city to allow the company to continue quarry operations for another decade. But there was one condition: the company had to pay all costs to fill the quarry pit with as much as 6 million cubic yards of soil and transform it into a regional park.

Once operations ceased in 2007, the company’s first proposal to construct a 20-acre fishing lake hit a wall, as regulatory agencies found there was no feasible way for lake water to flow into the bay, making it inhospitable for fish. That failure led some to lose trust in the company, as even park district officials two years ago wrote a letter to Fremont, questioning the company’s willingness to honor its deal with the city.

    “..it will be encapsulated by more than 50 feet of solid, clean dirt when the project’s done.”

    What does this mean?

    Will this 50 feet of solid, clean dirt prevent – for example – ground water from percolating thru whatever gets deposited in the quarry?

    Will it prevent that ground water from migrating soluble contaminants elsewhere?

    I’m wondering if a state of the art outdoor amphitheater can be built there? I am thinking something similar in to the Greek Theater or the SB Bowl where the venue is protected from the wind, but designed to fit respectfully in this environment like the Red Rock amphitheater does in Co.

    Just an idea. The remainder of Coyote Hills has been unaffected by the facility thus far. There is access and space for parking on the east side that would maintain the separation from Coyote Hills. If done right, Fremont would get it’s performing arts center, and a potentially world class concert venue in one go… and it much of it would be no cost to the city.

    Good idea, Marty.

    While we’re at it let’s instruct DQA to repurpose the Mowry’s Landing schoolhouse as an on-site facility for whatever purpose.

    The park already has an interpretive center. But it also seems like a historical structure such as this might be put to a variety of reasonable (and perhaps even revenue generating) uses if properly rennovated (for a REASONABLE cost).

    Think mini and less extravant variant on Ralston Hall or Tripp Store in Woodside.

    Please Protect the Tri Cities Environment
    Stop the filling of Dumbarton Quarry with toxic soils. The Soil is full of Toxaphine, A herbicide so bas the EPA have banned it since 1981, but was used since 1946. It is a powerful Carcinogen.
    It will contaminate the ground water with a toxic Toxaphine.
    Please attend the meeting and tell them not to poison us with Toxaphine, in the ground water. I thought Fracking was bad this is much worse.

    “We have a lot of restrictions,” (Mayor) Harrison said. “Also, it will be encapsulated by more than 50 feet of solid, clean dirt when the project’s done.”

    Huh?

    How does that address Toxaphene from floating into neighborhoods DURING the dumping process? It’s the windiest area in the Tri City area….

    Fun fact– Toxaphene: When inhaled or ingested, sufficient quantities of toxaphene can damage the lungs, nervous system, and kidneys, and may cause death. It is classified as an IARC Group 2B carcinogen.

    It is classified as an IARC Group 2B carcinogen.

    In good company with coffee and gas exhaust.

    (…playing devils advocate here. 2B means don’t bathe in the shit. But I still wouldn’t want a chemical product buried near my home).

  • Jasper Stein

    Would you like some in your coffee.. Toxaphine

    Short-term: EPA has found toxaphene to potentially cause the following health effects when people are
    exposed to it at levels above the MCL for relatively short periods of time: central nervous system effects
    including restlessness, hyperexcitability, tremors, spasms or convulsions.
    Long-term: Toxaphene has the potential to cause the following effects from a lifetime exposure at levels
    above the MCL: liver and kidney degeneration; central nervous system effects; possible immune system
    suppression; cancer

    there’s a little difference between carcinogenicity and toxicity.

    The IARC list deals solely w/the relative carcinogenicity of listed materials, e.g., the relative ability of the substance to produce cancer in organisms.

    Toxicity, on the other hand, is a different kettle of (floating) fish. It’s a measure of how quickly the substance kills you. So – while breathing automobile fumes may (or may not) cause cancer – it’ll certainly kill you in short order. Similarly, the carcinogenic effects of Toxaphene are, according to available data, not clear.

    It’s toxicity, however, is well understood.

    It’s ability to accumulate in organisms is well understood.

    It has been banned in just about all parts of the world NOT because of concerns as a carcinogen but because it tends to kill living things and it doesn’t go away.

  • bbox231

    Correction – it *does* go away – - very, very slowly, mostly through evaporation.

  • Marty

    ^This is why water is toxic in “sufficient quantities” but has no ability to cause cancer.

    I am just being critical of Dan-O’s cut and paste job. The terms “sufficient quantities” and “Group 2B carcinogen” are meaningless, though the sound terrifying.

  • Jasper Stein

    Toxaphine was banned in the USA in 1981, it is now banned in most all countries.
    At the Patterson site they have been trying to clean the Toxaphine from the soil.
    It has not worked! They are still trying. It would cost a fortune to haul off the contaminated soil.

  • Bbox231

    Kinda like the word “encapsulated” sounds reassuring as do flimsy comparisons between a designer poison and coffee or water …..all of which are ill informed extremes aimed at inviting knee jerk conclusions. What is not hyperbole is that this shit was designed to kill organisms and doesnt go away quickly.

    Die young stay pretty…Could anyone get really get away with putting excessive/toxic amounts of one the “dirty dozen” in our water supply? I will belive this can happen when there’s a lake ta the North Pole.
