RE: Lake Cochichewick Watershed Protection District;
Proposed Lot Development at Lot #1, Dale Street
Water Quanity and Quality Evaluation
Dear Atty. Hatem,
This letter report represents a Water Quality and Quantity
Evaluation associated with the above-referenced project consistent
with the Special Permit requirements for proposed developments
within the Town' s Watershed Protection District. The purpose of
this Evaluation was to assess whether the proposed project would
have a significant negative effect on the water quality of Lake
Cochichewick. In performing this evaluation, Normandeau Associates
reviewed the proposed site plan(dated April 12 , 1995) , conducted a
site visit, reviewed the Order of Conditions prepared by the North
Andover Conservation Commission(NACC) as well as the revised
Watershed Protection Bylaw(Oct. 24 , 1994) and the Lake Cochichewick
Watershed Plan(IEP, 1987) .
The proposed project consists of constructing a residential
dwelling on a one acre lot located on Dale Street which is in the
upper headwaters of the Batell ' s Brook subwatershed. The site is
about 1. 3 miles from Lake Cochichewick as the stream flows. Runoff
generated within the property drains into bordering vegetated
wetland along the eastern and western edges of the property which
outlet into a large wetland area on the other side of Dale Street
and then eventually into Batell ' s Brook. Soils onsite in the upland
areas have been mapped as part of the Canton-Charlton complex which
are described as a well-drained soils with relatively low runoff
potential (SCS, 1981) . The backside or southerly edge of the
property essentially coincides with the major drainage divide
between the Lake Cochichewick and the Fish River watersheds.
The Batell ' s Brook subwatershed consists of 368 acres which
make up 13 . 4 percent of the total watershed to the Lake (IEP.
1987) . At the time the Watershed Plan was developed, the principal
land uses within the subwatershed consist of forested, residential,
and pasture areas which comprise roughly 47 , 26 and 14 percent of
the subwatershed area, respectively. Without accounting for any
additional residential development that occurred in recent years,
the proposed project, using the entire lot area, would add about
1. 0 percent to the total residential area within the subwatershed.

/ As shown on the site plan, only about 15 percent of the lot
area or 6 , 500 sf will be disturbed to accomodate the structure
footprint(1, 613 sf) , paved driveway(1, 200 sf) and associated
grading. The house will be connected to the municipal sewer system
through a new force main that will be installed along the north
side of the Dale Street right of way and will tie into the existing
sewer main several hundred feet east of the site.
The primary water quality concerns associated with this
project relate to the added nutrients, particularly phosphorus and
nitrogen, potentially contributed from various sources. Phosphorus
is of concern because of its effect on the eutrophication process
in the Lake. Nitrogen, in the form of nitrate-nitrogen, can be of
concern if drinking water contains levels above 10 mg/l. Since a
septic system is not required with this home development, one
principal source of nutrients has been eliminated. The remaining
sources relate to the potential nutrient contributions from lawn
fertilizer and soil erosion.
Based on water quality sampling results presented in the
Watershed Plan, the annual phosphorus inputs from the Batell's
Brook watershed is estimated to be 103 pounds (lbs) or about 8
percent of the total load to the Lake. Based on literature values,
contributions from residential areas are expected to range between
0. 31 and 0. 54 lbs/acre(IEP, 1987) . Using an average loading rate
of 0. 4 lbs/ac/yr, the phosphorus load from this site would amount
to about 0. 4 percent of the total phosphorous contribution from the
Batell's Brook watershed and 0. 03 percent for the entire Lake
watershed. Given the minimal site disturbance, discussed above,
and the lack of septic system inputs, loading from this particular
site would be expected to be considerably lower and would have
negligible impact on the Lake particularly with respect to the
existing residential areas within the watershed.
With respect to nitrogen, the point of concern is not so much
the lake but at the property boundary where groundwater recharged
onsite may enter a well used by an adjacent landowner. The NACC
Order of Conditions requires that only low nitrogen content
fertilizer(i.e. , generally considered to be less than 20 %) can be
used. The nitrogen content in commercially-available lawn
fertilizers generally ranges between 5 and 35 percent depending on
the manufacturer and type of material. As an example, the SCOTTS TM
Turf Builder generally contains 32 percent nitrogen with a
prescribed application rate of about 16 pounds per 5000 sf of lawn
twice a year (Spring and Fall) .
N®RMANDEAU ASSOCIATES
page 3
For purposes of estimating a worst-case, nitrate-nitrogen
concentration at the property boundary on a average annual basis,
it was assumed that fertilizer with 35% nitrogen content was
applied four times a year at 16 lbs per 5000 sf.. (As discussed
earlier, given the site plan layout only about 3700 sf would be
available for lawn area after discounting for the driveway and
building area) . This -translates into a total application of 22 .4
lbs of N per year. Most of the applied nitrogen would be utilized
by the vegetation or bound up in the soil. Previous studies have
documented minimal nitrogen losses to groundwater from turfgrass
fertilizer applications(Starr and DeRoo, 1981; Morton et al. ,
1988) . A study conducted at the University of Rhode Island found
that only 13% of the applied N was lost to the groundwater at an
application rate of 28 . 5 lbs/ac/yr and under overwatering
conditons (Morton et al. , 1988) . Again, to provide a conservative
analysis, 50 percent or 11. 2 lbs of the applied N is assumed to
enter the groundwater.
To determine an appropriate dilution volume, it was assumed
that 50 percent of the annual precipitation(i.e. , 43 . 0 inches)
evaporates or is transpired by vegetation, leaving 21. 5 inches to
infiltrate into the groundwater or travel as runoff. The soil in
this area has been mapped as the Canton-Charlton complex, which
consists of well drained soil with relatively low runoff potential
(SCS, 1981) . At a minimum, about 50 percent or 10. 75 inches of the
available water would be expected to infiltrate into the
groundwater. Additional recharge from watering is not included.
As a result, given the assumed loss of applied N and the
estimated groundwater recharge onsite, an average annual nitrate-N
concentration at the property boundary is estimated to be 4 . 6 mg/1.
This concentration based on worst-case assumptions is well below
the drinking water standard of 10 mg/1. In reality, with a low
nitrogen content fertilizer, as required, a normal application rate
of twice a year and a realistic assumption of plant uptake, the
nitrogen concentrations in groundwater are likely to be a fraction
of the above value that is based on conservative assumptions.
In summary, given the size of the proposed development, its
location within the watershed, the minimal amount of lot
disturbance as presented on the site plan and the results of the
nutrient loading analyses discussed above, I would not anticipate
any adverse effect on the water quality of Lake Cochichewick as a
result of the proposed project. With respect to soil erosion
measures, I find that the proposed hay bale/silt fence barrier
should be more than adequate given the amount of disturbed area
proposed, provided the barrier is installed properly and maintained
until vegetation is re-established.

Re: Lot 1 Dale Street
Dear Mr. Colantonio,
As per our discussion this afternoon I am sending you a copy of the
application, plan, and watershed report concerning Lot 1 Dale
Street. I have also enclosed a copy of the current Watershed
Protection District rict Bylaw.
As you will see from the application, there is a legal issue
concerning the appropriate bylaw. The lot was created in 1985
therefore the applicant is asserting that the 1985 bylaw applies.
We are asserting that the 1995 bylaw applies. I have sent this
issue out to our town counsel for a resolution. Therefore, please
hold off on the actual review of the project until this issue is
resolved.
However, I would like your opinion as to whether your firm is
qualified to conduct this type of review. The current Bylaw
requires:
1. Written certification from a registered professional engineer
(or other person trained in hydrogeology) that the project not
cause any significant degradation of the quality of quantity
of water in or entering Lake Cochichewick.
2 . Proof that there is no reasonable alternative location outside
the non-disturbance zone.
3 . Evidence that all on-site operations including but not limited
to construction, waste water disposal, fertilizer applications
and septic systems will not create concentrations of Nitrogen

RE: Engineering Review
Lot 1 Dale Street
Special Permit
Dear Ms. Colwell:
As requested, Coler & Colantonio, Inc. has reviewed the submittal prepared by Merrimack
Engineering Services. The Application is not dated, however the plans are dated April 12, 1995.
It is our understanding that the purpose of this review is to evaluate the Application for
conformance with the requirements of the Watershed Protection District as they relate to a
Special Permit Application for a lot created prior to 1994. It is our further understanding that the
Bylaws dated"Final 10/13/94"are the governing regulations.
We offer the following comments:
1. The parcel lies within the Watershed Protection District. The site is a 43,874 square foot
parcel of land on the southeasterly side of Dale Street. Wetlands flank both sides of the site.
2. The proposed limit of work is within 37.5 feet of wetlands along the west side of the site and
43 feet on the easterly side. The Bylaw requires a setback of 100 feet as a non-disturbance
zone.
3) The limits of the "Non-Disturbance" zone are not indicated on the plan as required in the
` , Bylaw. The entire locus lies within the"Non-Discharge"zone.
4. A report addressing the impact of site development on water quality in Lake Cochichewick
was prepared by Normandeau Associates. If the Board is not familiar with the
typequalifications of work„�Quld be pro vdedcratThe�analys sntpresented qualifications
eason reasonable the
individual site except as noted below. The Planning Board should also consider the
i"i � iti .. y quality
...,,. . i . .. �p . We
incremental degradation of water ualit in the lake due to other similar projects.,
question the assumption that onl 3700 s ure feet of the site will be landsca ed area,,, The
plan indicates a zone of approximately 10 to 15 feet around the building and driveway as
the limit of work. This will be difficult to enforce after construction and provides very
limited construction
work space. It is likely that a future homeowner.would wish to expand
” stated A restriction on the deed limiting the developed portion of the lot
to the area stad should
the yard, area to the lot.,be required as part of.any,approval.

Norwell, MA 02061-1685 Fax: 617-982-5490
5. The elevation of the cellar floor in the proposed building is below the elevation of wetland
areas on site. It is likely that groundwater lj.be,ericountered in the excavation for the
cellar and will be a problem relative to infiltration of groundwater into the cellar.
Typically, this would be controlled through the use of a sump pump. The regulations
require that designs recharge runoff to the extent feasible if a sump pump is used this
_m w
would have the effect of pumping groundwater to a surface discharge point. We
recommend that a test pit be excavated and observed by a certified soil evaluator to
estimate the maximum seasonal high groundwater table. The proposed cellar floor
elevation should be a minimum of one foot above this elevation.
6. The plans indicate a grass Swale which would collect runoff along the easterly side of the
building for discharge across the driveway to Dale Street. It also appears that a small
depression on the easterly side of the proposed driveway, in the Dale Street layout would
be created. We do not recommend creating a trap for water in the layout of a public_street.
The proposed swa el——w—oufd-discharge to an _e isting zditch along Dale Street. The
`regulations require that site runoff from impervious areas be .recharged__to the extent
feasible. The proposed Swale does not address this requirement Based on the report by
go--r ndeau Associates, soils on the site should be suitable for on sh' recharge.
C7) It does not appear possible to grade to the limits shown on the plan along the westerly side of
the driveway in the vicinity of the proposed 196 and existing 198 contours.
We appreciate the opportunity to assist the Planning Board on this project and hope that this
information is sufficient for your needs. If you have any questions please do not hesitate to
contact us.
Very truly yours,

DATE: December 10, 1985
TO : Planning Board
FROM: Willie Vicens, Chairman
SUBJ: Coventry Estates
The NA CC visited the project site several weeks ago, held, a public hearing on
the Notice of Intent for this project on Wednesday December 4th and Tracy Peter
visited the site again. on Thursday December 5th, Based on these site visits and
public hearing we have determined that some additional information is required
before we can issue an Order of Conditions. Copies our letters to the applicant
have bden sent to you.
Overall we have the following comments on this project:
1. Watershed District: The portion of the site fronting on Dale Street lies in
the watershed district. It is likely. that we would,impose conditions to re-
el
strict development within 100 feet of the wetlands on Lots l through 5. Such
restrictions may make these lots unbuildable.
Extent of Wetlands: We believe the wetlands on the site are more extensive
than shown on the plans dated November 8, 1985. Specifically, there are
wetlands on Lots 72 through 16, and Lots 31 and 32.
3. Runoff Control: The current project does not include runoff control measures
or the portion of the property draining to South Bradford Street. This is
unacceptable to the NACC and provisions must be made for on-site or off-site
runoff control.
4. Steep Slopes: Some of the lots will have very steep slopes. Both temporary
erosion control during construction and permanent stabilization after completion
should,be provided in these lots (e.g. , 17 through 30) .
We hope these comments are of help.

PLANNING BOARD
Principal Points upon which Application is Based
This lot was created in 1985 as part of the Coventry
subdivision. A preliminary subdivision plan was filed
The definitive subdivision plan was approved by the
Planning Board on December 16, 1985 . The Planning Board endorsed
the plan on MBW04N 2 y ► 1986
The property was subject of litigation with the North
Andover Conservation Commission which began in May, 1991 . The
litigation concluded in Essex Superior Court in May, 1995 . The
I
Conservation Commission's appeal of a Superseding Order of
i
Conditions issued by the Department of Environmental Protection
(DEP) is pending, but the issue is expected to be resolved along
the same terms as that of the Superior Court litigation.
The lot is subject to the provisions of the zoning bylaw in I
i
_Zfect when the preliminary subdivision plan was submitted. The
eight-year zoning freeze provided by MGL c. 40A s . 6 , and MGL
c.41 s. 81Q, is extended by the period of any litigation
involving the right to develop the property.
Under the zoning bylaw in effect in 1984 , no construction is
to take place within one hundred ( 100) feet horizontally from the
edge of tributaries of Lake Cochichewick except by special
s
permit.
The applicant believes that the current plan meets the j
conditions for a special permit listed in Section 10 . 31, par. 1,
Items a. through e. , of the 1984 bylaw. Specifically, the
single-family home proposed for the site is :
a. An appropriate location for the residential use proposed;
b. Will not adversely affect the neighborhood;
c . Will not be a nuisance or serious hazard to vehicles or
pedestrians .
Further,
d. Adequate and appropriate facilities will be provided for
the proper operation of the proposed use, viz. , the dwelling will
be connected to town water and the site is sewered; and
I
e. The proposed single-family dwelling is in harmony with
the general purpose and intent of the bylaw.
Enclosed with this application is a Water Quality and
Quantity Evaluation report from William R. Arcieri, Senior Water
Quality Scientist of Normandeau Associates . He concludes in the
report that there will not be " . . .any adverse effect on the water
tality of Lake Cochichewick as a result of the finished
project. "
The primary water quality concerns associated with this
project relate to nutrients, particularly phosphorus and
nitrogen, potentially contributed from various sources . Mr.
Arcieri's report contains a detailed explanation of how each of
these added nutrients will be handled.
Further, under the North Andover Conservation Commission's
Order of Conditions , soil erosion measures, including the
required hay bale/silt fence barrier should be more than
adequate, given the reduced amount of disturbed area.
I
i
An earlier application to the Planning Board for a special
Pf
3rmit contemplated a house with a footprint, seventy ( 70) feet
wide by thirty-four (34 ) feet deep. The house was oriented across
the lot, reaching toward each of the wetlands .
The current proposal--which has been approved by the
Conservation Commission --is for a structure with far less
impact. It calls for a footprint only thirty-two ( 32) feet wide
by fifty-nine (59 ) feet deep.
Other lots in Coventry have obtained special permits for the
construction of single family homes within one hundred ( 100 ) feet
of a lake tributary. [See special permits granted for Lots 2A
and Lot 3A]
Moreover, at least twenty-six (26) special permits for
construction of single family dwellings within 100 feet of a
tributary of Lake Cochichewick or a wetland in the Watershed
Protection District have been granted by the Planning Board from
1982 to the present, many substantially closer to the lake or a
major tributary.

Comments:
Heidi,
We have reviewed the submitted "Water Quality Evaluation"for Lot#1 Dale Street performed by
Wetland Preservation Inc. dated October 5, 1999 for conformance with the Town's Watershed Protection
District Bylaws. This study indicates no significant impact to the Water Quality of Lake Cochichewick.
Reportedly, the proposed nitrogen loading will be 1/10 the required minimum drinking water standard
and the proposed phosphorous loading will cause a 0.05% increase in the loading. The loadings, as
reported, were modeled using the development of the entire lot and are thus conservative in their results.
If you have any questions, please call me 781-982-5434.

The project soils are predominately hydrologic group B(Canton CaB and CaQ.Thus,a depth of 0.25 inches over the
project's impervious area(2,878 sq.ft rooftop and driveway)will be used;
(2,878 sq.ft)(0.25 inches)/(12 inches/foot)=60 cu.ft
Check Available Inflow Volume from Rooftop
Using the 2 year-24 hour runoff depth of 3.1 inches,and a CN value of 98 for rooftop, the depth of runoff equals 2.9
inches per SCS TR55 Figure 2-1. The available volume of runoff from a the proposed rooftop(1,612 sq.ft)equals;
(1,612 sq.ft)(2.9 inches)/(12-incheslfoot)=389 cu.ft
Check Dead Storage of Proposed System
Use 20 Infiltrator high capacity chambers(or equivalent)placed in a 7 foot wide by 64.5 foot long trench filled with
double washed crushed stone to a depth of 16 inches. Approximate stone void ratio as 0.33 of total;
Total System Volume=(64.5 ft long)(7 ft wide)(16/12 ft high)=602 cu.ft
Structure Volume=(20 units)(16.3 cu.ft)=326 cu.ft
Stone Void Volume=(602 cu.ft-326 cu.ft)(0.33 Vv/Vt)=92 cu.ft
Total Void Volume=326 cu.ft+92 cu.ft=418 cu.ft

5. The elevation of the cellar floor in the proposed building is below the elevation of wetland
areas on site. It is likely that groundwater will be encountered in the excavation for the
cellar and will be a problem relative to infiltration of groundwater into the cellar.
Typically, this would be controlled through the use of a sump pump. The regulations
require that designs recharge runoff to the extent feasible, if a sump pump is used this
would have the effect of pumping groundwater to a surface discharge point. We
recommend that a test pit be excavated and observed by a certified soil evaluator to
estimate the maximum seasonal high groundwater table. The proposed cellar floor
elevation should be a minimum of one foot above this elevation.
6. The plans indicate a grass swale which would collect runoff along the easterly side of the
building for discharge across the driveway to Dale Street. it also appears that a small
depression on the easterly side of the proposed driveway, in the Dale Street layout would
be created. We do not recommend creating a trap for water in:,`= layout of a public street.
The proposed swale would discharge to an existing ditch along Dale Street. The
regulations require that site runoff from impervious areas be recharged to the extent
feasible. The proposed Swale does not address this requirement. Based on the report by
Normandeau Associates, soils on the site should be suitable for on-site recharge.
7. It does not appear possible to grade to the limits shown on the plan along the westerly side of
the driveway in the vicinity of the proposed 196 and existing 198 contours.
We appreciate the opportunity to assist the Planning Board on this project and hope that this
information is sufficient for your needs. If you have any questions please do not hesitate to
contact us.
Very truly yours,

Re: Lot 1 Dale Street
Dear Mr. Colantonio,
As per our discussion this afternoon I am sending you a copy of the
application, plan, and watershed report concerning Lot 1 Dale
Street. I have also enclosed a copy of the current Watershed
Protection District Bylaw.
As you will see from the application, there is a legal issue
concerning the appropriate bylaw. The lot was created in 1985
therefore the applicant is asserting that the 1985 bylaw applies.
We are asserting that the 1995 bylaw applies. I have sent this
issue out to our town counsel for a resolution. Therefore, please
hold off on the actual review of the project until this issue is
resolved.
However, I would like your opinion as to whether your firm is
qualified to conduct this type of review. The current Bylaw
requires:
1. Written certification from a registered professional engineer
(or other person trained in hydrogeology) that the project not
cause any significant degradation of the quality of quantity
of water in or entering Lake Cochichewick.
2 . Proof that there is no reasonable alternative location outside
the non-disturbance zone.
3 . Evidence that all on-site operations including but not limited
to construction, wastewater disposal, fertilizer applications
and septic systems will not create concentrations of Nitrogen

in groundwater greater than the federal limit at the down-

4 . Projections of down-gradient concentrations of nitrogen,
phosphorus and other relevant chemicals at property boundaries
and other locations deemed pertinent by the Planning Board.
Please let me know if your firm will be able to do this type of
review. I will let you know when the legal issues have been
resolved. If you have any questions please do not hesitate to call
me at (508) 688-9535.
