The whole
'island' (NOT bridge) issue...simply blows my mind.
Bring in a reputable third party engineering company, not associated with Da Family or looking to milk a contract at the expense of the residents, and they will laugh at what a big deal is being made...about what is basically a small erosion issue.
Had the proper amount of armor rock/rip-rap been placed on the islands during construction, the relatively piddly amount of erosion (created only by wind induced waves, of a relatively small lake)...could easily have been mitigated.
The "fix" is to simply add a bit of fill material (compacted of course), place additional Class 4 (or 5) rip-rap...and it would last for another 100 years.
This could easily be done by cutting a road to the water line, using dump trucks to stockpile the material, a small dozer/track loader to spread/compact the fill materiel...and an excavator to 'PLACE' the additional rip-rap.
The truth of the matter is, that it was poorly-designed in the first place and the responsibility to fix it correctly...SHOULD be The Developer's.
And I guarantee it's NOT a 7 figure project...more like a low 6 figure one.
And yes, this is like
some of the type of projects...I oversaw in my previous life.
