Better start launching from the lower launch and make friends there so you can be a local there in two years. :mrgreen:

Re: 3rd upper launch erosion - done 2016
okay then. I like Dave's idea. a few hundred sandbags would probably make a pretty big difference...worth a try i figure.

Funny,
I emailed SFBA and Forster City and got Zero response over the week.
ok so back again as some knowledgeable people seem to read this topic. Who are the correct people to connect to in Forster City as want to connect to them directly. Please send them to me as PM if you dont want to see them in the forum.
I really doubt that one could sandbag this issue as we tried many years ago, the bags you see at low tide, and the result was zero. Really zero. We need a comprehensive approach to solve the issue.

Re: 3rd upper launch erosion - done 2016
I work for a public works landscape contractor and we have done some mitigation planting on the bayfront levee near the launch. maggiora and ghilotti was the GC and did all the earthwork and erosion control netting, my company then planted the site with 2000+ native plants after they finished. the work we did was for the city of san mateo.
This is a copy of the grading plan, erosion control netting was placed on top of the finished grades and secured with staples etc... then we cut holes in the netting for the native plantings.

The good news is with the shoreline eroding and the bay rising several brand new spots should be coming online by 2016

Re: 3rd upper launch erosion - done 2016
Dave is correct. Several years ago some good intentioned locals cleared an opening in the upper lake/cove so it would be easier to come in and land and relieve the congestion in the cove which is used to launch.
In retrospect, I believe this new gap created a greater/faster flow of water in and out of the lake/cove which I think may be the largest single reason for the erosion. In the short term, I think the fix may be refilling the gap with "sand bags." The sand bags would be the same as those that were used at Coyote Pt to build the ramps to the water. They would be filled with the same material as used at Coyote as the bags and filler have already been approved by the BCDC.
Also need to remember that the launching cove did not exist. It was manmade by Enrique who got permission from Foster City and who had the large equipment necessary. He moved rocks and built the point to the left of the launch cove. i don't know what if any this also affected the erosion.

Re: 3rd upper launch erosion - done 2016
I disagree. The rocks were moved ~2006 and if you look at the erosion graph it has been linear since 2000. Also, only a small section of rocks were moved, and these were added to the levy outside the opening. I suspect the erosion is combination of factors:n retrospect, I believe this new gap created a greater/faster flow of water in and out of the lake/cove which I think may be the largest single reason for the erosion.
- The original rock levy is sinking and breaking apart
- Rising sea level
- There used to be lots of plants in the cove but they were sprayed (invasive). I think this was around 2004.

Re: 3rd upper launch erosion - done 2016
Perhaps efforts should be put toward a much longer term goal of having kite bars with retractable lines. Launch your kite 5 feet away from you, engage mechanism to feed out lines, kite till your heart's content, retract lines, land 5 feet away. Then we too could launch from carpet-covered rip rap.
