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.
