Massachusetts by using biodegradable products that consist of coconut fiber. She describes the <br /> project as creating biodegradable sand bags that they cal Iift s which won't be tied on the bank side. <br /> They will be open into the face of the coastal bank. They will be filled With sand with material filter <br /> bags on the inside and wire mesh on the outside. It will be used for high-wave energy <br /> environments. Each bag is 16' L x 2} H and 16' back into the bank. The lot is 250' long and each <br /> one will have approximately 250 yards of sand in them. There will be 8 bags on the Tide watch <br /> revetment and 7 bags closest to Seaside. ,On the top, they plan to use four or five rolls on each of <br /> the sections which will actually be anchored into the bank but there will not be any anchors used in <br /> the lower half because the weight will make them stable enough to stay in place. The beach <br /> volume will vary but it is important to keep the structure covered so that the products do not brew <br /> down due to UV rays. They will place 12 31 <br /> 2" pilings on the seaward side which was approved through <br /> DEP. There will be pilings put on the front side which take up about 3' and it is right against the <br /> base of the bank to hold the bottom sandbag in place. <br /> Vice Chairman Shaw asks ghat type of vegetation will be used and Ms. Marden replies that they <br /> will be using beach grass. Agent McManus asks how far back the vegetation will go and Ms. <br /> (Marden-says that they want to stabilize the front face of the bank and the Agent asks of a buffer <br /> strip. IMS. Marden says that they �rork with Conservation regarding a buffer strip because it will <br /> benefit the client bort she wants to see if it can be stabilized first with beach grass. Mr. Sweet asks if <br /> there will be ars access point for the trucks to back in to dump the sand and Ms. Marden says that <br /> they will be coming in from the golf course but during construction they will be using the top of the <br /> lot to bring the materials down. They are anticipating to only nourish the lower half because they <br /> are hoping to stabilize the upper half with vegetation so they will not want to dump over the bank <br /> with the new vegetation. She believes that the top is at most 16' and they can get in there with the <br /> excavator and put in the sand. Seaside village is dome through the golf course and she also <br /> believes that they will be maintaining the easement between Tide watch and the New Seabury <br /> property where they always have access to beach nourishment. <br /> Mr. Gurnee asks about the material of the wire mesh and Ms. Marden states that is plastic coated <br /> wire mesh with two layers of fabric material. She states that approximately 5 gears, the Tient will <br /> probably have to do substantial repairs or replace the system. If the material-is dept covered, it i <br /> possible 7-10 years but will require constant maintenance. Chris Holmes from the manufacturing <br /> company explains that this product hail been used in several instances along the cape and is used <br /> mostly in high energy areas. It allows minimal movement a little more than the typical fiber rolls <br /> which allow it to withstand high energy a little longer. They are 4 times stronger than the typical <br /> ones that are all over the cape. Mr. Gurnee asks what the purpose of the core material is and Mr. <br /> Holmes responds that it will hold back the fine sands which will act more like a cushion or pillow for <br /> that. He also states that there are some of these projects that have been in place up to and over 1 <br /> years. <br /> Joe Coli ano who works for Bayswater Development for New Seabury Properties states that'they <br /> will be maintaining this on a monthly,basis and will use the same procedures as before in regards to <br /> storms. IM . (Marden responds that they are trying to maintain a lure of sand right now by constantly <br /> putting nourishment there but it just keeps moving. This material can be hit by a stormy which will be <br /> fine because it should still maintain that line of sand and it will just require another veneer of sand to <br /> protect it.from the elements. Fight now New Seabury is just putting loose granular sands which get <br /> sucked away so they end up nourishing massive quantities during one storm. This system will-act <br /> to stabilize the line. Chairman Fitzsimmons states that the'CoMmission does not have anyone that <br /> has technical expertise to be able to have an informed opinion on the project. Agent McManus <br /> states that Ms. Marden has been working with Jim IMahala who works for DEP as their coastal <br /> specialists and according to Ms. Marden, he is in favor of this project. The Chairman states that <br /> DEP will have to be relied on because of the complexity and Agent McManus says that he will be <br /> speaking with Jim Mahala. Mr. Sweet asks how they will keep the waves away while the bottom of <br /> the structure is being established. Ms. Marden responds that there are some stones already at the <br /> return and they will place more at the high tide line to break the wave energy. She also mentions <br /> .that they will have to remove some of the sand from the banks because the structure has to be <br />
