Dear Ms.Giffin:
Regarding the above mferenced project,we offer the following written response to comments:
In a letter dated 9-27-01 from Heidi Griffin,Town Planner to the Planning Board,
1. Specific measures have been incorporated in the pool design to prevent degradation ofthe
water quality&quantity emering the lake. The pool will be equipped with disposable non-
backwash filter cartridges. Each October,the pool water level will have to be lowered
approximately 6 inches,a zero chlorine level can be achieved before this operation is
performed. Additionally,an area for pool pumping has been designated to maximize wetland
separation,placed rip-rap in this area will prevent any soil erosion. Structural engineering
design plena will be presented to the town as required,The site plan has also beery revised to
require that the silt-fam be band-dug as requested.
In a letter dated 9-27-01 from VHB to the Planning Board:
1. (4.136.4.c.ii.2)Wetlands Preservation,Environmental Consultants,flagged the designated
wetland area shown on the plan. As discussed with the North Andover Conservation
Commission,the wetland boundary will be Held verified with their agent prior to issuance of
a bulling permit.
11. (4.136.4.e.iii)No significaut degradation of the water quality or quantity will occur tom the
proposed work. Additionally,the existing Conservation Reatriction and will be in effect to
further protect the resource areas.
III. (4.136.4.c.vi)No increase of nitrogen in groundwater will o=ur from the proposed project
IV. (4.136A.c.vi)Since no increase of downgradiertt concentrations of nitrogen,phosphorous,o
other relevant chemicals will result from this project. A waiver is requested from this item.
V. (4.136.4.8)The only increase in impervious area will be the construction of a 4-foot apron
around the perimeter. Due to the saub vegetation at the back oftht lot,and the distance of
the proposed pool to the resource area,a natural vegetative barrier exists to facilitate
removal and infiltration of surface water,
VI. The owner has agreed to secure within the dwelling,all chemicals required for the
main�&peration of the pool.
VII. No restriction exists that prohibits the construction ofthe proposed stone walls within the 20
sewer ea>reme nt
VW- The desip and ooh of the retaim"wails will adhaz to aft state and local
r'equhvimads.
