There is an existing crude dock towards the southern end of the site and the proposal is to remove tl i dock and replace with a new proper dock that would extend out into Great River. It will cross an area of salt marsh and extend into Great River r where the water depth exceeds two feet. It will extend approximately 26' beyond the edge of the salt marsh. Agent McManus states that the Shellfish constable gave him a plan and he would like to confirm that it i the revised plan. John Slavinski explains that they gave the Shellfish constable a plan that shows the original diagram along with the revised one but they did net put a revision date on it because he had wanted to wait until it was approved before dating it.- The Agent states that he will get an official letter from Mr. York for the file. Mr. Sweet asks if there will be some di turbain a to the vegetation on the upland side and Agent McManus confirms that the pathway will cut through some existing vegetation although a lot of it is invasive.

The proposal envisions a trapezoidal corridor above the inland bank which borders A humet Pond. corridor creation will require removing a few saplings and pruning the middle sections of limbs from the tall trees growing on the steeply sloping hillside. The project will be carried out by a registered arborit , Tim Green from Greens Tree & Garden.

The project is standard crista pruning protocols. chairman Fitzsimmons mentioned that there is a walkway shown on the plan that goes down to the resource area and asks if normally the width of the walkway is included In the amount of the crista corridor calculation.

They do not want to see it break free as all the water and runoff will go down in between the bridge, abutment and the road itself and then cause additional problems which will tie up the bridge for a longer period of time. The construction will be done by Jonathon croft from Lawrence Lynch who is present for any technical questions. The goal is to not tie up the bridge for more than one full day and possibly a second day because of emergency vehicles. In terms of the environmental impact, there is nothing that will go into the, grater because the work that Lawrence Lynch will do is to basically take up the black top and replace with new pavement. Agent McManus asks if there is a need for any erosion control and Mr. Croft answers that there will be which is outlined on the new'plan (highlighted in yellow). They will be using a silt fence barrier around the perimeter of the whole sight and attached to the outside railing on the water side.
