RE: VIOLATION of the Massachusetts Wetland Protection Act(310 CMR 10.00)
and the North Andover Wetland ByLaw (Ch. 178 of the Code of North
Andover).
Dear Mr. and Mrs. Doherty:
Visual inspection of the above referenced property on June 3, 1996 revealed violations
of the Massachusetts Wetland Protection Act and local Wetland ByLaw. Any activity
proposed or undertaken within an area specified in the Act (310 CMR 10.02)(1)(a)
which will remove, fill, dredge or alter that area is subject to regulation under M.G.L.
c.131 s.40 and requires the filing of a Notice of Intent with the North Andover
Conservation Commission (NACC) and Massachusetts Department of Environmental
Protection (DEP).
Furthermore, any activity proposed or undertaken within 100' of an area specified in
310 CMR 10.02(1)(a) (hereinafter called the Buffer Zone) which in the judgment of the
issuing authority, will alter an Area Subject to Protection under M.G.L. c.131 s.40 is
subject to regulation and also requires the filing of a Request for Determination and/or
Notice of Tntent.
Violations documented on-site are as follows:
• Alteration of a Bordering Vegetated Wetland (BVW) as defined under 310 CMR
10.55(2)(c) without a valid Order of Conditions from the NACC. Specifically, the
alteration consists of shrub and herbaceous layer clearing and potential grade
changes;
Under the local ByLaw a violation of this magnitude is subject to a $200.00 per day fine.
Each day that the violation is not rectified is constituted as a separate offense and
subject to additional fines. At this time I am not issuing a fine nor am I requiring that
the wetland be restored, however, the following conditions shall be imposed:
BOARD OF APPEALS 688-9541 BUILDING 688-9545 CONSERVATION 688-9530 HEALTH 688-9540 PLANNING 688-9535
• Cease and desist immediately from further alteration of this wetland resource area;
` • Appear before the North Andover Conservation Commission on Wednesday, June
5, 1996 at 7:00 p.m. in the Senior Citizens Center located to the rear of Town Hall on
Main Street.
North Andover was one of the first communities in the Commonwealth to organize a
Conservation Commission in 1961 when it adopted Chapter 40 Section 8C of the
Massachusetts General Laws. Since the passage of the Massachusetts Wetland
Protection Act in 1972, the Commission has rigorously enforced the provisions of this
Act. The Commission not only enforces the state Wetlands Protection Act, but also a
local Wetlands Protection ByLaw. This Bylaw (and its subsequent revisions) has been
in effect since 1979. Comprehensive Wetlands Protection Regulations were adopted
early in 1991. These regulations provide detail and performance standards to support
the local ByLaw. The Commission meets twice a month to review development
projects and issue permits for work near wetlands.
Please refer to the enclosed Enforcement Order and Violation Notice for further
information. I have also enclosed literature for your review in hopes of clarifying what
a Bordering Vegetated Wetland is and why it is important that we protect these
environmentally sensitive areas. Your future cooperation with regards to this matter is
greatly appreciated and I look forward to working with you in reaching an agreeable
resolution.
Sincerely,

BORDERING VEGETATED WETLANDS: Bordering Vegetated Wetlands are freshwater
wetlands which border on creeks, rivers, streams, ponds and lakes. The types
of freshwater wetlands a-re wet meadows, marshes, swamps and bogs. They are
areas where the topography is low and flat , and where the soils are annually
saturated. The ground and surface water regime and the vegetational community
which occur in each type of freshwater wetland are specified in the Act . The
boundary of Bordering Vegetated Welands .is the line within which 50 percent or
more of the vegetational community consists of the wetland plant species
identified in the Act . (BVW)

North Andover Conservation Commission
Buffer Zone Policy (1991)
The North Andover Wetlands Regulations identifies a 25 ' no-
disturbance and a 50 ' no-construction zone around wetlands. The
rationale for such buffer zones is included in this policy
statement. Upland buffer zones are not a new concept and much
study has been done, and is now underway, on this issue,
Vegetated buffer zones are perhaps the most effective way to
control nonpoint runoff. IEP Inc. recently prepared a document
for the Narragansett Bay Project entitled Vegetated Buffer Strip
Designation Method Guidance Manual that discusses this issue in
detail and provides a very useful annotated bibliography as well .
This and other sources, including some that will be cited here,
have studied wetland systems and proposed buffers that are, in
many cases, in excess of those generally imposed by the NACC.
Additional buffer zones can protect wetlands values and functions
in the Lake Cochichewick Watershed and may also be imposed.
The IEP buffer zone study recommended a minimum of 25 '
buffer zone for any wetland. One document prepared by the Corps
of Engineers generally recommends buffers measured in meters, not
feet. These buffers range from 7m to 200m. Buffer zones can be
a vital link in protecting water quality in many ways. This
includes:
Temperature
Shade and cover provided by riparian vegetation can
moderate water temperature in small streams.
Sediments and Other Contaminants
Buffer strips filter 'sediments and other contaminants
(e.g. pesticides, heavy metals) from surface flow.
Buffer strips also prevent erosion in ripar?an areas
and preclude development which could lead to increased
contaminant loading.
Nutrients (Nitrogen and Phosphorus)
Buffer strips reduce nutrient inputs into streams l
1) filtering sediment bound nutrients from surface flow,
2) removing nutrients from groundwater via uptake in
vegetation and by denitrification, and 3) precluding
development which could increase nutrient loading (i.e.
septic systems) .
Maintenance of Streamflow
Buffer strips can store water and help maintain stream
f base flow (and water quality) during low flow periods.
\ (U.S.A.Corps of Engineers, Buffer Strips
for Riparian Zone Management, 1991)
2
The Department of Environmental Protection the Wetland
Regulations (310 CMR 10. 00) clearly recognize the value of buffer
zones. The Preface to the 1983 Regulations states that "It has
been the Department's experience that any project undertaken in
close proximity to a wetlands resource area has a high likelihood
of resulting in some alteration of that area, either immediately,
as a consequence of construction activities, or over a longer
period of time, as a consequence of daily operation of. the
completed project. . . "
Also section 10. 02 (2) (b) states that any activity proposed
or undertaken within 100 feet of an area specified in 10.02 (1) (a)
which, in the judgement of the issuing authority will alter an
area subject to protection under the Act is subject to
regulation. House construction and grading within 25 ' of a
bordering vegetated wetland is, in -the opinion of the issuing
authority, work that will alter an area subject to protection
under the Act.
Section 10. 05 (6) (b) states that the Order of Conditions
shall prohibit any work or any portion thereof that cannot be
conditioned to meet the performance standards. This applies to
the buffer zone as well as resource areas. Some feel that it is
impossible to condition work and meet the performance standards
without the imposition of minimal buffer zones.
The State of New Jersey has seen a pattern of land
development similar to that of Massachusetts. There land use
controls and environmental regulations are also somewhat similar.
"In New Jersey, tidal and non-tidal wetlands are protected
by establishing a buffer between proposed development and
the wetland boundary. Law and policy have set the maximum
width of buffers for both types of wetlands, and the minimum
buffer with for non-tidal wetlands . . . One method for
protecting wetland from degradation is to provide vegetated
areas, or buffers, around wetlands. . . Non-tidal wetlands
that provide habitat for threatened or endangered species,
or that discharge to certain pristine waterways are
classified as wetlands of exceptional resource value, and
are provided with a 75 to 150 foot buffer. Most other
wetlands that are not man-made are classified as being of
intermediate resource value, and are provided with a 25 to
50 foot buffer. "
("Buffer Delineation Method for Coastal
Wetlands in New Jersey" , Symposium on
Coastal Water Resources, AWRA, May 1988)
In New Jersey, wetlands of exceptional resource value are
provided with minimum of 75 ' buffer while other wetlands are
provided with a 25 ' minimum. The same minimum used by the North
3
Andover Conservation Commission.
Pollution attenuation is one of the most important public
values provided by wetlands. Wetlands can become degraded over
time due to the influx of additional pollutants, or pollutants
can bypass the natural processes during periods of high flows.
Upland buffer zones can protect (and enhance) the natural
capacity of the wetland system to attenuate pollution. The
upland has its own pollution attenuation capacity as well. This
is an important factor to consider when assessing the` _cumulative
impacts of residential development on surface water quality.
Nitrogen and phosphorous inputs can be attenuated with the
use of upland buffer zones. The Lake Cochichewick Watershed Plan
discusses the 'potential threat of phosphorous as a result of
residential development.
"The potential of phosphorus reaching the lake from
fertilizers is greatest on properties that immediately
border the lake or a tributary stream. In these areas,
there is the potential for phosphorus to be washed off, the
surface of the ground into the water body, especially if
there is a good soaking rain storm shortly after the
fertilizer is applied. Phosphorus inputs to the lake which
can be indirectly related to lawn fertilization include
decay of lawn clippings or leaves which are deposited in or
near the lake or tributary streams. "
In a separate document ("Long Pond Newsline") IEP states
that 1130 - 50 ' wide buffer zone will remove about 70 - 90% of the
sediment and phosphorous in runoff. "
The Corps of Engineers recently prepared a document for the
k. State of Vermont to guide them in the use of buffer strips. The
role of buffer strips in nutrient removal is clearly articulated:
"Buffer strips can reduce the movement of nutrients f 'om.
uplands into surface waters. The primary processes involved
include: 1) retention of sediment bound nutrients
transported by surface runoff, 2) uptake of soluble
nutrients by vegetation and microbes, and 3) absorption of
soluble nutrients by organic or inorganic soil particles.
Sediment retention seems to be main process responsible for
removing phosphorus (at least initially) , while
denitrification is the primary process responsible for
nitrogen (nitrate) removal.
The nutrient removal efficiency of buffers probably depends
on many factors. These include sedimentation rates, surface
and subsurface drainage characteristics, soil
characteristics (particularly oxidation-reduction potential,
organic content, and temperature) , the successional status
of vegetation, and nutrient loading rate from uplands per
�. 4
unit area of buffer. "
This document discusses the value of buffers in protecting
wildlife habitat as well:
"Because buffer strips can greatly influence water
temperature and other habitat variables in low order
streams, buffers probably have a considerable impact on fish
and invertebrate communities. Few studies, however, have
looked closely at the effect of buffer strip width on stream
biota.
"Although the importance of riparian areas as wildlife
habitat is well documented (see Brinson et al. , 1981;
Motroni, 1980; Hopper, 1989) , little information is
available upon which to firmly base buffer strip width
recommendations. At a minimum, buffers should be wide
enough to provide habitat for species adapted to both
riparian "edge" and "interior" habitats. Also, the buffer
area (length x width) should be large enough to provide
adequate breeding and foraging habitat. "
The next two pages were taken from that Corps document and
illustrate many of the functional wetland values protected by
` buffer zones, recommended widths and references. This provides a
useful overview of the status of research as it relates to buffer
zones.

The role of the local Conservation Commission and the
Department of Environmental Protection is to protect the public
interest and the important wetland values that we all benefit
from. Both the Conservation Commission and the Department of
Environmental Protection "shall prohibit any work or portion
thereof that cannot be conditioned to meet the performance
standards. " (10. 05 (6) (b) The North Andover Conservation
Commission cannot allow this project without the impo§ition of
buffer zones. The imposition of buffer zones is the,Only way
that the Conservation Commission can protect various Interests of
the Act.
Without the imposition of adequate buffer zones projects
located immediately adjacent to wetlands will, in the opinion of
the issuing authority, alter an area subject to protection under
the Act. Therefore, the Commission is compelled to regulate this
activity and protect the interests of the Act through the
imposition of buffer zones. We feel confident that, although it
is a complex and relatively new concept for some, the value of
upland buffer zones is known. Buffer zones around sensitive
resource areas will prohibit the degradation of wetlands and
wetland values that the literature indicates will occur, and that
we are prohibited by the regulations to allow.
