Here are two views of the construction work on the San Vicente well.
The April 2018 DPG Pancake Breakfast was a great success with food, fun and funding. The only photo I have is this – most of the volunteer crew that put it all together, so if you have more photos or information please share.
Thanks to all for a great time in service of our community.
This afternoon we flew past SV and snapped pix of the drainage area above San Vicente. Here’s a wide shot.
Our main drainage is the small creek running up the center slightly toward the right. The main drainage from the mountains runs to the left behind the top of that first low hill of the San Marcos Foothills open space. In a major flood that’s where the vast majority of runoff would go. Even if SM Foothills was burnt bare, any debris flow would be relatively minor here at SV.
You can also see the smaller channel that drains to Cathedral Oaks from the left side of the pic. Also potential for flow down 154 that would collect below the overpass. All that water drains through the culvert that feeds the channel through our open space. In a major flood that would overflow and/or get plugged by debris so the water would then spread out and head downhill, probably mostly along roads as it spread out beneath the overpass.
A closer look shows how our main creek leads down to the Foothill/154 underpass.
There, in event of an overflow at the inlet to our culvert, the electrical substation might be impacted. That whole area would flood, and eventually some might enter SV and/or begin to flow to the left on Cathedral Oaks and/or right on Foothill. This seems to match the small SV flood risk areas on the map published here related to the 2015 El Nino prep meeting (click to view). Some of our streets might flow with water and Rancho next door might be more impacted in such an event.
San Vicente became “Pole Land” today as a tall crane lifted new power poles into place, and residents came out to “supervise.” We’d been notified that power would be off all day, but the crews seemed able to work while keeping it (mostly) on.
It happened that we got these two views of the SV well on a recent flight. To me they demonstrate the heroic work being done to preserve and protect our well while future improvements and alternatives are being studied.
Here are some aerial views taken 2/18 after the heavy rain, of the flood channels that run through SVMHP down into Arroyo Burro Creek. First is a look at the inlet (bottom of pic, just right of center) to the box culvert that runs under Foothill at Hwy.154. Note that the top of the pic is toward the Southeast, unlike the gMaps image at the bottom of this post.
Next an overview, with the inlet at the bottom near the left corner and the new Sansum clinic at the top-left.
Below is a look at the wide grass channel it opens into (bottom-left), that runs across SVMHP into Rancho SB golf course.
There’s another storm water inlet (right of center, beneath trees & shrubs), to a culvert pipe that runs under Cathedral Oaks from the Northeast intersection with Via Chaparral across from the SVMHP back gate. It comes out on the corner of SVMHP near the bend of Stage Coach into Indian Wells, and joins with our larger channel on the Rancho golf course.
When we feared flooding last year, the County cleaned debris from both of these two inlets at our request, so they wouldn’t flood across Foothill / Cathedral Oaks thus limiting our access and emergency exit routes. Lastly, here’s a look more toward the East, at the Rancho SB golf course where these two storm channels join.
The footbridge near the top-left is where our channel enters Rancho, with SVMHP homes on Gatehouse across the top. Here’s a link to a satellite view on gMaps: https://goo.gl/maps/QeJxhmeCVo32
Below is a gMaps screen capture of this area (North at the top) from drought times back when Sansum was being built, with a pin about where our box culvert inlet is, next to the electrical substation.
