She explains currently that it is a dirt road with a significant topography and very narrow in width. They have also discovered that there are a few utility issues with the water and gas lines installed in the middle of the road. She also says that there is one area, as you enter Horseshoe Bend property from the Falmouth end, where there is a wetland area that the road is very close to. She would like propose installation of drainage up from the lover point and also on the opposite side as you go down the hill to try to capture the Stormwater before it reaches the low point in the wetland. Because of the high ground water, they are proposing a slightly different drainage system than what they normally use. They would like to install galley chambers in the road itself. Agent McManus states that this is an isolated land subject to flooding and is very close to the road layout which right now is just unabated runoff going into the wetland. It Inas been slowly filling in . over the years so any kind of adjustment to the drainage pattern will be a.tremendous benefit. It is also a certified vernal pool and he is highly in favor of the change to the drainage pattern. Ms.- Laurent would life to add the request for a couple of trees that may to be removed as part of the project. Agent McManus suggest possible mitigation to make up for the trees to be removed. Mr. Allen asks if they will install some sort of oil separator and M . Laurent responds not an oil . separator specifically but they are proposing a separate solid catch basin that will be tied to the galley chamber. This separate structure will capture any sediment and oil which will be cleaned on n annual basis. Mr. Cross asks if the gas line will be moved to the side. Ms. Laurent states that the gas company is not proposing to do any work on their rain line but it is erg.closed in concrete in that specific area.. Mr. Gurnee is questioning the fact that a plan is not required for this project as it is near a certified vernal pool. Agent McManus mentions that this resource is currently being affected by the conditions of the road and these changes would vastly improve it. He believes that these types of projects where it Inas significant improvements should be moved along quickly. He suggest that Mr. Gurnee can make a motion if he would like to see a more detailed plan but Agent McManus feels that he has sufficient details on this project and it is all beneficial to the resource area. Chairman Fitzsimmons recommended allowing this as an exception but as a general rule it seems a,pin is required for ICDA submittals. Mr. Gurnee would like_ to see a better plan for this project and asks for one from Ms. Laurent once they get started on it. M . Laurent states that she will provide something additional, possibly a surveyed plan of the road. Motion rade and seconded.d. In favor: Chairman Fitzsimmons, V.
