Conservation Commission December 14, 1989 Page 8. Mr. Sherman stated he has reservations with the project and did not agree with the staking for the top of the bank, it is further away from Santu i t Pond than is shown on the plan. Performance standards for an inland bank indicated work should not impair the physical stability of the bank. He felt putting the foundation over the edge of the bank will impair the stability of the bank. He was also concerned with wildlife habitat. He was unsure whether calculations had been done to show the extent of area that constitute the deck and stairs coverage. Mr. Thorng asked if' Mr. Sherman would agree that under the deck is very flat and the top of the bank is the first major break in slope. Mr. Sherman agreed, but stakes on the site are below that Point. Mr. Thorng stated he had ,not checked the survey crew but on the plan i t is clearly shown. Mr. Sherman agreed with the Plan but felt Mr. Thorng should check the site staking to resolve the matter. Mr. Thorng stated there will be no structures on the bank; the wall is on the edge of the flat spot. Mrs. Simmons stated this is not indicated in the staking. Mr. Throng stated the supports for the deck will be angled into the wall so there will be no posts in the bank supporting the deck. Mrs. Simmons suggested that the proposed addition go out no further than the railroad ties. The staking is incorrect and the Commission feels there is a considerable amount of land that could be used. She requested that the lot be restak d and Mr. Thorng agreed to restake and make an overlay. When asked if steps would be exactly where they are presently, M . Thorng stated they would. Steven van Tot presented a landscaping plan. Mr. Sherman questioned the nature of the charges approved in the septic system, Mr. Throng advised a decision was to be rade, working with the Board of Health, as to whether to keep the laundry and wet bar downstair or half bath and wet bar. The decision was rude tonight by his client that the laundry will be going uptairs and they will apply to the state for low-flow ejectors for the wet bar and half bath. Mrs. Simmons asked how long this will take and was told thirty days. Mr. Thorng asked to continue.
