Tustin Military Base Could Be Toxic.

the ramp mentioned is the approach for the future bridge crossing edinger. they generally will overbuild it, let it sit for a while and settle, trim to grade, and finish construction.

Why not just use concrete?

To set the bridge in an incline ramp there must be a land mass. Concrete is fine like you said but it will take hundred thousand cubic yards of concrete for this project. Concrete per cubic yard =$$$$$$ while Dirt = Free.
 
Dirt is not exactly free. It must meet certain grain size distribution and compaction guidelines. If the local dirt is of poor quality, you will need to import and that is most definitely not free. Still cheaper than concrete though.
 
i'd like to see them try and form it, a blow out on something like that would not be pretty. don't forget to factor in the cost of rebar that will be required. structurally a concrete approach is a bit of overkill.



most soil in irvine is really rather a pain, too much clay.
 
Expansive soil with too much clay or adobe soil is subject to expand because of its coefficient of expansion and contraction is quite large. For the application of a bridge ramp the dirt is position above ground away from saturation of water. Water is the ingredient that caused the molecular distance to increase in clay when being saturated. The dirt will be protected from moisture by the bridge and ramp and the exposed dirt surface below the bridge will also be sheathed with concrete and the side often are concrete abutment or buttresses therefore the the adobe nature of the dirt played a negligible role in additional structural requirement since the dirt is sheltered from moisture.

I was just thinking this morning that given that so much of the land in OC was agricultural before it was housing, there are probably a fair number of chemicals in the land a lot of the homes are sitting on. For example, DDT was often used as an agricultural pesticide and was not banned until 1972.



Paging Mr. No_Vaseline. Can you enlighten us about agricultural pesticides?
 
Thanks for the insight, everyone.Add it to the list of why I wouldn't buy in VOC (even if I could afford it). This is something I would hope people investigated, but then again, if they bought homes at 2006 prices... I am going to be forwarding the cleanup information docs to a buddy who moved there. Although he already bought, he can be a little more informed.



Does anyone see a movie starring John Travolta (a la A Civil Action), based on VOC, 10 years from now?

I actually worked for the lawyers who defended this case in Boston. You wouldn't believe the amount of documents this case created - rooms FILLED with documents.</blockquote>


I'm sure that was quite the case - documents that could fill up a warehouse, probably.
 
Come on people...

Pollution is underground at the El Toro and Tustin bases. Luckily, it is required by law not to leave the confines of the area it started. Over the last 50 years it did not indeed spread under all of Irvine and Tustin, and stayed in horrific concentrations on the bases. The US government hates you and is only concerned with money and power and therefore did a halfass job cleaning up the site using three daylaborers, a pickup truck full of dirt, and a garden hose.



On the other hand, the rest of Irvine is completely clean. Decades of unregulated farming and pesticides across the area generally has little to no effect on quality. By all means plant your deep rooted fruit trees anywhere but Columbus Square.

I don't mean to troll here but this group think gets old sometimes. If you're worried about pollution and the air you breathe then don't dry clean your clothes that's the biggest step you can take.



Here's my example If you accidently drop your favorite mug in the toilet, then scrub it for and hour, then bleach it for two days. Put it back on the shelf. Is that mug safe to drink from? Yes. Would you ever touch it again knowing the history? Heck No. The difference between most of El Toro airbase and Oak Creek is that you know one history, you don't know the other.
 
Did Oak Creek used to have orange groves or strawberry fields? Shady Canyon and Turtle Ridge used to have cows. Newport Coast used to have a landfill.
 
DevonMiles,



I don't think it is groupthink. The contamination issues have received extensive news coverage, and 99% of the public has no idea how contaminated groundwater and soil is remediated. I also think that confidence in government is at an all-time low. Additionally, they were still finding buried treasure as late as November 2007.



I am in the business, so I know how remediation works, and sometimes does not work. I also know that environmental contaminants are much more prevalent than most people know.



As for pesticides in the area, there are legacy pesticides, and they can get re-released when land is graded for new development, but it isn't a serious problem.

You're not invited to my next dinner party if you bring up that in conversation again!

funny thought, but so wrong.



the water recycling plant treats it to near-pristine, then pumps it into the aquifer so far that they calculate it will take 100 years for it to get to the zone that they pump back out from.

Ah! But will it kill me before my cell phone does?
