Debris torrent at site of recent culvert replacement. This should not have happened. There hasnt been enough rain to cause this under normal circumstances. A salmon bearing stream runs a few hundred yards below this road failure.
The equipment operator pulled out all the coyote bush by the roots adjacent to the site, and accidentally changed the rd hydrology just enough so water came straight down the road instead of into the culvert.
Notice the coyote bush that wasnt pulled, on the left and right of the debris torrent has not slid. A lesson to be learned, let coyote bush stand near culverts outlets. And road equipment operators who understand hydrology are extremely rare, and worth their weight in gold.
Lucky i collected a bunch of ca wild blue rye grass (Elymus Glaucus) earlier in the year from this site. I will seed it this week.
