Attention: Mr. Paul Lamprey
Reference: Stonecleave Estates
Dear Planning Board Members :
At the public hearing held on May 2 , 1977, several questions
were brought up with respect to the reference subdivision. You
requested at that time that T respond to these questions . The
following is submitted for your consideration.
1. Drainage Easement on Lots A & B
Both drainage easements and culverts under Boxford
Street will be shown on the definitive plans. Lots
A & B will also be shown on the definitive plan
such that easement rights may be preserved. These
corrections will be placed on the definitive plan
during the twenty day appeal period.
2. Dry Hydrants_
in cooperation with the Board of Public Works, 1
have been able to outline a standard detail for
dry hydrants . This standard detail will consist
of a North Andover specified Eddy Fire Hydrant
as called for under the rules and regulations
governing the subdivision of land. These dry
hydrants will be serviced by a 611 Class 150 John
Manville Blue Brute Pipe from said hydrant to a
point fifteen feet (15 ft. ) into a water reservoir.
Said pipe to be located three feet ( 3 ft. ) below
the water surface. Attached to the end of the
pipe will be an R.E. Chapmann type strainer. The
dry hydrant will be painted red in lieu of the
standard orange and yellow markings to denote
"dry tybe".

I have located two such dry hydrants on the enclosed
topographic plan at .lot lines 29 & 30 and 14 & 15 .
The hydrant at lot line 14 & 15 will be serviced
by the Mosquito Brook Pond to the rear of lot 14.
The dry hydrant at lot line 29 & 30 will be ser-
viced by a 10, 000 cubic foot reservoir to be
constructed where an impoundment area exists at
the location shown on the topographic plan en-
closed. Easements will be dedicated to the Town
as shown on the topographic plan enclosed. These
improvements will be indicated on the definitive
plan, if approved, during the twenty day appeal
period.
3 . Stationing
Stationing was inadvertently left out at the
definitive plan submittal. Stationing will be
placed on the definitive plan during the twenty
day appeal period, along all P.C. ' s and P.T. ' s.
In addition, the beginning and ending station will
be so designated.
4. Continuous Drainage
The highway surveyor , in his correspondence to the
Planning Board, requested continuous drainage along
Stonecleave Road. This , I feel, has been accomplished.
Enclosed you will find the computations for said
continuous drainage.
5. Designers Certificate
Enclosed you will find a properly executed designers
certificate.
Should you have any further questions , please feel free to contact
me.
Yours truly,
