Dear Ms Eggleston
In accordance with the discussion I had with Judy Tymon of the Town of North Andover Planning Board, the following is
our response to comments issued by you in your correspondence to the Board dated March 26, 2012:
1. No Comment required
2.Atty Lavoie is preparing a document that provides for maintenance of the drainage system by the owner of the property.
Also see Operation and Maintenance(O&M) plan we have mailed to you. It is referenced on the plan as well. j
3.We have added a reference to the sensitive use restriction and underground structures have been designed to inhibit
vapors from entering them. See O&M plan as well.
4. The owner will have an LSP on site to direct testing and handling of soils during construction (see O&M plan)by the
contractor.
5.Roof drain system and gutters added to the plan.
67he owner has elected to not use a roof cistern on site for irrigation of the landscaped areas
7.The planning board has evaluated the amount of copper designed on the building and elected to keep the design intact
with the copper.
Please do not hesitate to contact me, should you have questions or comments on the above, or after you receive and

Judy and Gene
I discussed with Gene Willis his report and we have revised the plans addressing his comments as follows"
1.Atty Lavoie has determined that Franklin Street is Private at this location and and we have revised the plan to reflect
same. He is preparing a report that indicates this(Mobil) property owner has the right to enter into the utilities including
the storm drainage system, at this location and will submit that to the Board as a separate document.
2. Atty Lavoie will prepare a document that details the property owner maintaining the proposed drainage Swale in
perpetuity upon approval of the plan by the Planning Board.
3.We are mailing both of you a copy of the Dynamic-Simultaneous Model and the analysis has the catchbasins and
manholes modeled as ponds. There is also a calculation indicating the capacity of CB1 Grate.
i
4.The proposed 130 contour was shown. It is not next to the rim of the catchbasin but about 25'from it toward the bank.
I am sure this was an oversight in the review.
5.We have revised the plan to relocate the Swale further to the east and the use of the land is not inhibited by the land
owner(insurance company)abutting the Swale. There is sufficient room to stockpile the snow at the end of Franklin
Street. We also updated the plans with the conditions existing 4/30/12 as an inspection of the property yielded the fact
that the Insurance Co did some work early winter and this spring at the site.
6.We have added the rip rap requested to the plan although our calculations show it is not needed.We added a rip rap
Swale detail to the plan.
7.We have provided a grading detail at the forebay and catchbasin inlet.
8-We have added a detail to the trash rack facility making it removable
9.We have specified that the swale be planted with 100%Kentucky Bluegrass.
10. Per my conversation with Gene the cleanouts at the end of the roof drain are not necessary as cleaning can take
place by accessing the drains at the downspouts and there is a overflow on each downspout however we did add 3 line
cleanouts to the plan.
Please review the attached plans and contact me should you have questions or comments about the above,the enclosure
or the model when you receive it.
