INTEROFFICE MEMORANDUM
DATE: April 3, 2012 comment #2
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 have
the following questions:
1. What will the velocity of stormwater discharging from the outlet of the
proposed drainage system be during a 100 year event?
2. Will this create scouring in the swale?
3. Will there be a need for energy dissipaters, check dams, etc. in the swale
to prevent scour?
