Louise Behr an and Mary Marsters stepped down. Jeff Oakes of Flynn Engineering presented an amended Notice of Intent. First Hole: Berns are shown to collect any runoff. There are three Red Maples in the standing water; thirty trees in the wetland will be taken down to stumps; the existing ground cover and shrubs will be left intact* Mrs. Ferriday suggested they top some trees and replace some with lower growing shrubs. She asked if there will be signs to remind people to stay out of certain areas. . Oakes agreed this could be written into the order of Conditions. He advised it is proposed to put crushed stone down to keep the existing path; . 6 feet wide of crushed stone brought in with a bobcat. Mr. Coffey asked if fertilizers had been addressed and was told It was in the Notice of Intent and would be the slow release type. f s. Ferriday stated, when writing up the order, more information on irrigation and maintenance would be required. Second Hole: Mr. Oakes stated they now propose to leave the Kettle Hole as is. They will excavate from elevation 38, where water is now, down to 24 in order to create a fairway pond. The isolated land subject to flooding is indicated on the plan with a red line. There is a plan for pond excavation where- they would stockpile the shrubs, excavate, then replace shrubs. Mrs. Ferriday asked the amount of pond residue to be removed and was told 1691 cubic yards taken from the bottom, probably used as topsoil in another area on the site. Test pit information was available; they went down to 7-1/2 feet at elevation 33. Concerning irrigation, Mr. Oakes stated there is an existing well 1100 feet away, tested, pumped at a rate of 20 gallons per minute' for five days. A well 400 feet from the monitor well only showed drawdown of 3 inches. Mr. Burns asked if it would have any effect on the pond and how deep is the well . They are 80 - 90 feet versus 28 feet. It was stated when they ran it for a number of days It only dropped 3 inches. The land is graduating from 24 up to 80 feet on the plan. When the well was monitored, it only dropped 3 inches in 5 days; his point is that Mr. Oakes stated it shouldn't have any effect of pulling water. He stated the elevation should be specified, Mrs. Ferriday asked to have the elevation of the well put on the plan, Mr, Oakes stated the surface elevation has no bearing on the ground water elevation but agreed to the request. Lisa asked to have the edge of the wetland moved back 15 feet on one side and Mr. Oakes agreed to extend the line. Mr. Burrs stated vegetation should be maintained. . Oakes asked that the Dearing be closed and any problems ironed out after.
