bottom. Mr. Buckingham was wondering about the drain coming from above that was very heavy with water. Mrs. Studley asked if the perched beach concept is going to be used in this area also and Mr. Kuebler said "partly" - in front of the wall. Mr. Dias wanted to know about the cement things and Mr. Kuebler said that the concrete block would be lifted out and put in other area -- there are abort 89 of them Kor 8 or 9 - say it fast and si e if you can figure it out: Mrs. Sloane said that she thinks they should do it and do it right, Mr. Braman said that ghat they are doing is stabilizing the bottom of the bank. There were no further questions and the hearing moved on to the perched beach concept. It was said that hurray Kirsner, representing the Rock Landing Assoc- iates, was advised - fir. Kolb and Dr. Shore are the abutters. Mr. Kuebler said that he thinks all of the members knows having lived here a lot longer than he has, that the configuration of our beaches are changing all the time and ghat basically happens to a beach aspect of a shoreline is that it re- ce ove s nourishment during the year - then this sand is scoured away by wave action dtiring other parts of the year. When you have a. serious storm, you generally have erosion of the bark, which may, for a period of time nourish your beach., He mentioned the sand than was lost along the Triton-Sound area f their property and said that if one has been do-vm do-v, there recently, one would see that the wave action has already started to scour the beach again. If you went along the Maushop area, you would see the rocks have already sham up again - the sand has been scoured from the top of the rods and is moving out to the ocean. He has pictures that demonstrate what's h pp ening to our shoreline pictures of Popponesset Inn and area in front of it taken in 19t' 2 and one that was taken earlier, He showed a series of pictures that were taken right after the storm in front of the Cabana Club, Beach Club and Poppon- e set Iran. The reason for the pictures is to slow how dose the erosion has roved in on the buildings. He said that when he was here at theJan- uary 19th meeting, he had mentioned the concept f the sandbags. As far as they've been able to determine, the use of sandbags to perch beach, which is to recover the sand that the ocean scours away from the beach, is the best technology that they have available. He brought an article with him which describes basically what a perched beach is. attached. He continued by yJ ng that one f the people that has been involved in this is Dr. Connor from MIT and, tinder a ,sea grant study, has been in- strumental in assisting various places on the Cape that have installed the sill that we '-re talking about -- Morris Island, Eastham and Dead Neck, Mrs. Studley asked what -sort of a plan he had seat to the state on this. Mr. Kuebler said they haven't developed the plan yet - he needs guidance. He said they feel that this should b .installed in many locations along-the beach front. He also said that it is a proven technique. He has examined the question of shellfish along the shoreline from the golfs course towards Sandy Peach and has had scientists there from Foods Hole who are. experts in s he l if i sh,ing and who are pre pared to come to talk to the C omm s s i on. In thein opinion, there is no shellfish in this area.. Mrs. Studley said that the Commission would only require a. letter from thea. Mr. Kuebler said that the question is "will it work?" He said they are going to spend an awful lot of money to see if they can recover and maintain their* beach. He said they are willing to take the risk. The bags can just be cut if it's not working. He said they know it's working on the Cape and want to try it here. He also mentioned that it doe ntt endanger
