■ <br /> Charlie reported that, based on.the information submitted to the Board, the plans and Coastal <br /> Engineering's letter, it is his opinion the testing was done in conformance with acceptable <br /> engineering practice and it is his recommendation this can go before the building inspector for <br /> permit application but it-should include all of this information (testing, reports etc.). The safety <br /> factors have been net. <br /> Public Questions: <br /> Lloyd Allen, Southport resident, he was a materials engineer. He suggested chemical'spiking of <br /> the wall, it can turn sand into bedrock; has been used widely in construction of the big dig. <br /> Might be easier than building a new wall. <br /> Charlie said he'd have to look at it, not in a position to recommend it now. Also, the blocks are <br /> available <br /> Paul Johnson, Southport. retired engineer. Questioned long term settlement of the wall. <br /> John Bologna of Coastal engineering discussed this. Base of the wall is excavated 4 t below the <br /> wall, test borings were done to 25 ft. Settlement is not a concern. <br /> Coastal looked at-redi rock calculations and did their own independent evaluation to verify. <br /> The extra toe wall on the bottom will ensure it maintains stability. <br /> Dennis asked if Cons Corn was involved? <br /> Mr. Bor�vie said the wetlands are more than 50 ft from the wall 0-90 ft). He has spoken with <br /> the Cons Corn argent. They have hired an environmental consultant who is filing an RDA. <br /> Dennis asked if any tree or vegetation must be removed because of the toe wall? <br /> Mr. Bonvie said possibly, may be able to work around there. Mr. Bologna will be on staff for <br /> the endre implementation and completion of this wall. - <br /> The Board received two letters from Linda Fletcher, Southport resident on the safety of the wall <br /> and future liability. <br /> The Board discussed concerns about chain of responsibility since the plans were, tamped''by one <br /> engineer and report was stamped by Mr. Bologna. <br /> Nis. Fletcher's letter asks if a geo grid would be safer with a wall that high. <br /> Mr. Bologna said the wall would have-to be taken apart to install. <br /> Is this design as safe as geo grid? <br /> Mr. Bologna said, with re-enforcement, it has a higher f actor of safety. <br /> Torn asked the safety of adding a 4 ft toe gall vs. keeping 21 ft high wall with geo grid? <br /> Mr. Bologna would prefer a loner, terraced gall. <br /> Ms. Fletcher asked that the wall be built at the manufacturers minimum requirements. <br /> Mr. Bonvie said the manufacturer allows urn re-enforced wall at the height it is now. <br /> Lee said the bottom line is - is this wall safe or isn't it? <br /> Mr. Bonvie said based ons standard engineering practices it is safe. <br /> Lawrence Shubolt, Southport, suggested the building inspector has to make the ultimate decision. <br /> Mould ask the manufacturer to give reassurance that they accept the handling.of their rod uct. <br /> 1 p <br /> 4 <br />
