WETLAND PROTECTION ACT HEARING
Municipal Building Committee, Town of Mansfield- -Hope and Pratt
Streets -- Public library /Council on Aging facility
Plans presented by Design Partnership's Dave Fisher were dated 11/13/87,
with the exception of pages L1 and L2. Approximately 4500 square feet of
wetlands will be impacted; a compensation area of 6000 sq, ft. is proposed.
Hay bales, siltation fences, and as riprap along the steeper slopes were
proposed. The ditch has been relocated. According to Mr. Fisher, the project
should result in additional flood storage and reduced velocity in a 100 -year
storm. The commission requested additional information about plans for soil
placement /replacement in the compensation area, drainage /grading details, and
a 20 or 40 -scale cross section of the current and proposed ditches. They also
noted that a wetlands replacement plan must be filed and will probably be part
of the Orders, Dick Lewis suggested that Sabatia should go in now to do an
inventory of vegetation before snow falls.
MOTION: To continue until Dec. 14 at 7:35.

Cabot, Cabot and Forbes -- Forbes Boulevard -- Construction /development
of a building along with related parking, utilities, and drainage.
Mssrs, David Grant and John McKinnon from Moor Associates presented plans
showing engineering for maximum development of the parcel in question. They
proposed a closed drainage system, with pipes and detention ponds, designed
for a 30 percent reduction of peak flow in a 100 -year event. Staked hay bales
were shown on the plans. Dick Lewis requested a detail of the riprap at the
end of the pipe..
NOTION: To continue until Dec. 14 at 8:00.

Neponset Associates - -Witch Pond II; South Stree t, Lots 71,. 72, 95,
Assessor's Nap 1-- Wetland crossing to impact 42.,,720 square feet.
John Parmentier of Dunn Engineering described the -project; Mike Stanton
and Bill Zoppo of Neponset Associates were present. The owner has land in
Foxboro (Witch Pond I) which abuts this project, butt ticcess through Foxboro
has been denied by the Foxboro Planning Board. Hence, the applicant considers
this a "limited project" and therefore proposes no replication. According to

the figures submitted, the project will affect 42;720 sq. ft. of wetlands and
bridge a river. It has not- -yet been filed with the Army Corps of Engineers.
Wetlands flagging was done by Mr. Parmentier, who has attended DEQE
seminars on wetlands identification, Dick Lewis had questions regarding the
calculations of percentages of various wetlands species, as well as
reservations about several types listed as upland species which Dick's sources
list as typical wetland indicators, Mr. Parmentier noted that he didn't count
numbers of plants but made visual judgments only.
Dick Lewis questioned how the calculations of square footage were made;
the limit of work line is not equal to the limit of excavation line, and
calculations 'do not incorporate any activity between the limit of excavation
and the limit of work. Dick's calculations in this area resulted in a figure
of 42,769. The area cut and graded for the hydraulic connection to the river,
according to Mr. Parmentier, was not included in the calculations, though he
acknowledged that some cutting and clearing would have to be done. Dick
estimates a total area of 43,857, which would trigger the MEPA process. Mr.
Parmentier stated that the Secretary of Environmental Affairs has not been
notified because "we intend to keep it under that limit; we will maintain that
it is below one acre."
MOTION: That wetlands be delineated by a professional botanist and that
replication be required.
(OUELLETTE - GRADY; all in favor) VOTED
Dick went on to question Mr. Parmentier about the flood zone and a 152 ft.
elevation shown on the plans; Mr. Parmentier could not resolve an apparent
discrepancy between Dick's flood maps and the applicant's elevation
figures /calculation at this time.
MOTION: To request additional information regarding flood zone /elevation
calculations.
(OUELLETTE - O'NEILL; all in favor) VOTED
Mr. Burdon Blanchard, the Water Superintendent for the City of Attleboro,
