Our Cliffs Are Dry, So They Fall
Here is a Union Tribune story about dredging offshore sand and dumping it on the beach to help prevent the cliffs falling, a better solution than seawalls.
The offshore sand will be the good stuff, not the horrible river sand the city of Encinitas used to import in the 80's and it won't be dirt (see post below).
There is one thing I never hear anyone in charge talking about, the cliffs are no longer drippy.
What? Drippy you say?
When I was a kid the cliffs were wet, damp and dripping. Ever build a sandcastle at the beach? You use the damp wet sand to build it because it sticks and stays up. The dry sand crumbles. The physics of sandcastles.
Think also, concrete. What do we mix with concrete to make it strong? Water!
It is the same with our cliffs. When I kid the dripping bluffs were covered in blooming flowers and red ripe wild tomatoes. Yes, there were slides from time to time but the bluffs seemed much more solid then than now.
My guess is that the cliffs no longer drip because we have paved over so much of North County that the rain no longer soaks into the soil and gradually makes its way west via percolation and osmosis.
Now the rain rushes down the roads (through downtown Leucadia) and into the ocean. This run off may keep costing you an extra 5 bucks by the way (on top of the $110,000 we collectively put up as taxpayers. Our city looooves it's consultants!) link
Anyone that has lived here for more than 30 years can confirm that the area bluffs were drippy, not dry like today.
What can we do? Probably nothing at this point. It's only getting worse as the sprawling San Elijo Hill's continues to build out. So if you own a multi-million dollar home on Neptune Ave. shake your angry fist east towards your new neighbors.
Dredging offshore and dumping sand will help the cliffs but probably destroy the quality of the surf for a few weeks.
I humbly request that the city do the dredging in June when the weather and surf is horrible anyway. Please do not do it in the fall when the surf is good.
