Stormdrains from Tar Pits to Ballona
December 7, 2011 § 5 Comments
Since this post about tar on Ballona seems to have generated a lot of interest, I thought I’d also provide you with an image of LA County Storm Drains from the Tar Pits connecting to Ballona Creek. The oil sheen I referred to in my previous post is visible at Cochran Avenue, at the upper end of the blue line representing Ballona Creek here. As mentioned in my prior post, if tar is coming into the creek from the tar pits, it should be apparent downstream between Marvin and La Cienega (I had previously said Fairfax). As you can see here, there are a tangle of drains, which I assume means there are overflows built into them from one drain to the next. Very large drains outlet at Fairfax and La Cienega, bringing in flows from as far north as Beverly Hills and West Hollywood (and the south slopes of the Hollywood Hills beyond them). And as many know, there are active oil wells in this zone, so it is fair to speculate there can be tar in these neighborhoods too. While my photos clearly show tar seeping in from above Cochran Ave, I perhaps should clarify that there could be other sources related to other occurrences (that I’m unfamiliar with) on Ballona Creek. There’s tar to go around for all of us!
If you’re kind of an infrastructure nerd and don’t know about Navigate LA yet, by all means you should poke around this fun site. I’d have used their maps to explain this better, but alas, my browser no longer supports it.
