Conservation Commission Meeting of June 2, 1988 Page 3. Mr, Grassetti stated Lisa will have a single source of coordination at the site. This is a single source job and there will be no other activity. Ms McKelrey stated the wetland was flagged by her this spring. By law she had to flag it because it was hydraulically connected and there was standing water. As far as vegetation, it is indicative of an upland area. In her opinion, to replic- ate it would do more damage. Mr. Grassetti stated it really has trees and vegetation which are not rally rep- resentative of a wetland area. The only time this has been wet was the 70 year high. The approach by the botanist and engineer was to treat it as if- it might be wet some day, as a failsafe. If it is not a wetland, perhaps it will not be necessary to replicate one. Lisa stated they are replicating it by putting in the pipe. Ms Behrm n suggested an amendment to delete this, listing the reasons-, because the vegetation is upland and appears to be an intermittent stream of very scarce flow- age, Lisa asked how long the pipe is and was told it was 40 feet. Ms Behrman stated this should be on the plans rid in the Notice of Intent. She sled if there, would. be any further- road drainage coming down and Mr. Grassetti stated none at all . A very extensive road drainage study has been done. It is all captured in recharge areas throughout the project, Mr, Coffey asked about timing and was told the best time to do this would be Spring or Fall . Mr. Grassetti stated they are requesting to do this as soon as possible, consistent with the Board' s ability. Ms Behrman stated the Board is looping for amended material with deletion and the length of pipe specified. Also, it should be indicated on the plan where the pipe will start and stop. Mr. Grassetti agreed. CONTINUED PENDING RECEIPT of AMENDED MATERIALS. HEARING To BE CLOSED UPON RECEIPT AND ORDER of CONDITIONS ISSUED. Mr, Grassetti presented a summary report by Mr. Ingram. He will physically go to the nursery and choose the trees. Ms McKelrey stated she and Jiro did a series of studies at the site of the altered area. A letter was submitted previously. on the 18th a planting study of crown diameter of areas lost was completed. The total area involved i s 15 acres. The number of trees were studied adjacent to that area. Jiro found there were 18 strong mature trees cut down. He did a regression study and found it necessary to replace not only the feature trees, but the crown diameter lost due to the cutting of trees. They will be putting back 18 - 81 to 10' trees, 2" diameter and -also crown diameter lost, He proposes to plant 1 o un erstory shrubs; 40 high bush blueberries; 40 Arrowood; 40 low bush blueberries and 20 surface berries. The 18 feature trees are going to include 6 English oaks and 12 White oaks. Mr. Grassetti advised a small diameter well will be put in to water with Mr. Coffey questioned stump sprouting and Ms McKelrey stated this works well with any deciduous trees
