The pier is to be fixed to prevent it from sitting on the bottom of Nash pee River at low tide. Board of Appeals approval has been received. Ms Behrman stated the water is very shallow and asked if this is not a problem with boats? Mr. Thorng stated he believed so but it is the lesser of two evils, a choice of having your dock and boats as opposed to just the boats. Ms Behrman expressed concern with the impact on the ecosystem and boat scouring. She asked if there were proposed mitigating atin measures and Mr. Thorng had none. She also asked when the retaining wall was built and was told it is existing, date unknown. She then asked if there was an order of Conditions for this lot. Mr. Thorng stated not to h i s knowledge. Mr. Sherman advised the application is as a result of detection of work in progress. The dock had been taken out by high tides at various tires; it is part of an o 1 d existing structure. The Shellfish Warden advised the eastern side of Great River is a s oftsh e l l clam area; he has not found shellfish past the low tide marl. The river is murky and he d i d not fee l scouring wou l d be a problem or that boating in the area wil.1 increase by this one project. He would not want to see boats tied up along the fixed p ier and grounding out on top of the shellfish; this was agreed at Board of Appeals. Ms Behrman asked if a railing on the side could be installed to discourage a boat on that side. Mr. Thorng would be willing to come up with a solution. A railing is proposed up to the fixed walkway on either side, it could be continued. Mr. Coffey asked if a smaller pier would be a consideration. Nor. Thorng advised Mr. Leon owns a 26 ft. boat which is the reason for the 30 ft. pier. The distance to Mean High Water is 2-112 ft. Ms Behrman asked the depth at Mean Low Water and was told the soundings were done at low tide. It will be right on the bottom at low water. Mr. Caffey asked how it will be installed? Mr. Thorng stated a small barge with a crane and a pile driver~; fixed 4 X 4 posts in the marsh will be in- stalled by hand with a porthole digger; 8 inch diameter piles past the harsh to the end of the fined pier will be driven to rejection,
