“Stabilizing” San Ramon Canyon
July 21, 2010 § 5 Comments
The Palos Verdes Peninsula is mostly developed – but canyons, with their wily waters and sediment movement – and landslides – remain – to the chagrin of whoever lives in their path downstream, or whoever carves a road through their eroding banks. Today that would be a senior citizen’s mobile home park in San Pedro, and Palos Verdes Drive East, respectively.
Tonight there will be a meeting to discuss, as the Daily Breeze puts it, “stabilization” of San Ramon Canyon. I went out a few weeks ago to look at the offending canyon with a creekfreaky friend and what we noticed is that there are relatively small catch basins at Palos Verdes Drive, which can easily be blocked by the rocks coming down from the canyon. (We didn’t hike up to view the landslide area or potential impact to Palos Verdes Drive East, so no comment there. Photos in a Palos Verdes city powerpoint are illustrative of the problem-link below) But for the flooding part of the issue, as so often seems to be the case, it’s the catch basin that’s the problem, a hydraulic constriction interfering with the flow’s path. It was almost as if the road’s drainage system had been designed to flood.
It’ll be interesting to find out what their stabilization concept is, my hope is that the city’s experts know how to think creek.
Meeting: Miraleste Intermediate School, 29323 Palos Verdes Drive East, 7PM
