NEGATIVE rONO 2 SPT to cons truc t a single family dwelling with attached garage, well, septic system and 14�� 20' deck t 31 l obska Road. Mario Di regorio and Roger 1cHevish presenting. A 20 scale plan was provided. The lots are p* back lots; this one is 15,100 s.f. Abutter notification receipts for the two lots were provided. Immediately east of the lot is Bordering vegetated Wetland. The project proposes a two bedroom single family dwelling with well and septic system. All lots surrounding are serviced by private wells. A well easement is proposed for #39. The limit of work for- both wells will be 5 Feet from the wetland line, The closest point of construction is 30 feet from the deck. For proposed mitigation designs, see Notice of Intent. They have applied for a variance from the Board of--- Health. ealth. `o lawn area is proposed and a 30 foot wide natural buffer will be untouched along the limit of work. Nitrate loading will resuIt- in a 7.62 ppm. Temporary access for th .well will be a 36" wide trench and well installation for both lots will be backfilled i ediately and alloyed to revigetate to its preconstruction condition. A hayb le line will be installed the entire length of the l3imit of work. All disturbed areas within the wore area will be stabilized with Bch covering and/or a temporary erosion control seeding until more permanent landscaping vegetation is established. There are actually three dry ells for runoff. Driveway will be of crushed stone Concerning the septic, Ir. McNevish stated the primary concern was the proximity to the Bv . The well/septic locations for previously putted surrounding lots were a problem such as on lot 36B, the next one-,9ver to 38. That is why the well is located on lot 39 for lot 38. The 150 foot requirement of the Board of Health cannot be met on any lot in this subdivision. ,Application has been made to the Board of Health for the appropriate variances. . Sherman stated he could not find the stakes for the wells at his on-site. He was told they were staked after he had left* He asked to go to the site again 4 with Mr. DiGregorio. The width of the path to the well is wider than he thought t on previous filings. More retail may be needed on reveget tion, distribution, species and spacing. He stated the Codon usually asks for 50 feet for buffer -but this could not be met on this lot with the setback from the street. He suggested intensive revegetation once the well is in. Mr. DiGregorio agreed and asked if 4 ft. off center for one gallon shrubs sounded reasonable? That will give % coverage in two growing seasons,. 71 . Mr. Fitzsimons asked, in the event the proposal exceeds the 5 ppm, as long as -4k �- here is no lawn and a two bedroom house i's proposed will the Commission accept this? v Mr. Sherman stated this was adopted until such time as the Title v reqs come out and or until such time as we have definitive nutrient loading thresholds for Waquoit Bay and Popponesset Bay. -, g -Mrs. Ferriday accepting � stated the �o��s �on is not locked into a tin p g this ; ' it can be denied - r.- e,Y ' r
