Conservation Commission Page 1 * October 29 , 1987 Mr,, ,Coffey asked if this is to keep the service road from caving in and Ms Lan hauler stated , basically, that is it, VOTE: Motion made and seconded to accept the amendment to the Order of Conditions on 43-642. The chairman asked if all questions were resolveon the relocation of the cranberry bog pump horse , construction and maintenance . ear- Ig ILosed _ 9: 15 - Daniel Hostetter., Willow Bead , Continued from 10/15/87 (Water and Sewer lines) Revised plans were presented showing th.e water line on Quinaquisset Ave. Because of the steepness of the shoulder of the road on the northerly side of Quinaquisset, the Commission, the applic- ant and his representative all agree the water line should be moved elsewhere -which will have less of an impact on the pond. Ernie Virgilio and the engineers at BSC discussed this and the water line was moved a minimum of two feet off the pavement as Bauch as four feet into Quinaquisset, crosses on top of the culvert and goes over the top of the culvert 6 feet below the center line grade of the road and therefore -they can get the minimum 4 feet below the surface to avoid the frost line. The pipe will be insulated as it crosses over thecul- vert. There will be no izpact oto the bog as they wily be inside the guard rail and also coo riot .have to excavate under the culvert. Ms Behrman stated steps will have to be taken to ensure digging does not so below the 4 feet. s -L nghauser stated that would not be to their advantage to do so. She advised the sewer line is unchanged . It will be emplaced in a con- crete casing to additionaly additionalensure any chance of leakage and will travel along adjacent to the hog and come back up on the shoulder o f the road, A limit of workalone the edge of the layout would adequately protect the wetland. The distance by the wetland is 130 ft There will be a trench at least 4 ft . wide and a dewatering system will be needed. They will be working under the stream and as they ex- tend 90 feet , they will be working in ground mater and, at the low paint, will have to put in a pump to pump the ground grater out of the hole* They will pump is to a suitable spot for discharging. There is an area where a three sided siltation screen could be out with the pump in the center and -allow water to run across the -surface. It would not behoove anyone to put it up on the road or on the bog. The only other .locations could be the bog ditches, keeping in mind when this -is rehabilitated as with all the other hogs, they will take a mude at and- clean out the ditches* She stated because :he pipe is laid underneath the machinery , in order to keep the limit of work as narrow as possible, it is excavated and laid at the same time and the machinery travels over the sane pathway a minimum o f 15 ft . There will be a section- of bog that will be dug and replaced. s - Behrman requested a plan showing the discharge, points for the water when pumping it, Ms L anghauser agreed and stated it is not on the plan as the engineer instructed her tb stay general .
