TO: Judy Tymon
FROM: Gene Willis
CC: Tim Willett
RE: Lot #498 Chickering Rd. Plan of land
I am receipt of plans, sheets 1 to 5, by Merrimack Engineering Services
dated Jan 20, 2012for a Proposed Bank Facility at the above address. I offer
the following comments:
1. The existing ¾” water service to be abandoned must be terminated at the
main.
2. All proposed drains should flow to DMH1
3. DMH 1 should be a deep sump manhole
4. The proposed FES drainage outlet should be relocated from DMH 2 to
outlet from DMH1 with the swale extended and transverse to the slope.
5. There should be a rip rap berm across the end of the proposed outlet
swale.
6. There should be a flared end w/trash rack at the inlet to the existing catch
basin on the north side of Franklin St.
7. There is no detail showing the proposed work and finished conditions in
the area of rip rap and pipe end tying into the existing catch basin on the
north side of Franklin St.
8. The proposed new 126 contour is not shown.
