Re: Wetland Assessment Findings
15 West Street
West Hatfield, MA
Dear Mr. Reed,
In accordance with our approved contract, GZA reviewed the above referenced property, 15
West Street, for the presence of wetland resources. We offer this letter report to provide an
overview of our wetland assessment and findings.
Introduction
On Friday, October 14, 2016 two wetland scientists from GZA conducted a wetland assessment
on the above referenced parcel to determine the physical features of potential wetlands on the
Site including identification of vegetation, soils characteristics, and evidence of hydrology (i.e.,
flooding or inundation). Wetlands were delineated using the methodology outlined in the 2012
Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Northcentral and
Northeast Region and consistent with the Massachusetts Department of Environmental
Protection 1995 Delineating Bordering Vegetated Wetlands Under the Massachusetts
Wetlands Protection Act (WPA) manual. The field data forms provided are those prescribed by
the most recent Corps methodology.
Existing Conditions
The parcel at 15 West Street is a 4±-acre commercial property, with two buildings and paved
parking areas, bordered by a field on the southwest and northeast sides. During a 2009 project
building addition project, a wetland creation area and multiple stormwater management
features were added to the site (DEP No. 175-125). A town line divides the west side of the
property between Hatfield and Northampton. According to the Natural Resources
Conservation Service (NRCS), soils onsite are mapped as moderately well drained Amostown
fine sandy loam consociation. The site conditions were considered normal for the time of year
and weather conditions were at an “extreme drought” at the time of the assessment. There
are no mapped areas of FEMA 100-year floodplain or Natural Heritage and Endangered
Species Program (NHESP) Priority or Estimated Habitat of Rare Species.
Assessment Findings
Multiple channels were observed onsite, an intermittent stream with bordering vegetated
wetland (BVW) in the forested area beyond the property limits. Where the intermittent stream

channel enters the property, the channel splits and flows in a shallow channel southeast for approximately 275-
feet towards a constructed wetland and north along the western property line for approximately 345-feet in a
shallow, vegetated swale. At northwest corner of the property, the stream crosses under an unpaved access road
in a small culvert. The Bank resource was delineated along two narrow channels that run from south to north
along the western property line. The channel is shallow and vegetated, but is maintained as part of the field,
having been recently mowed. The Bank boundary was demarcated in the field with sequentially numbered
flagging and labeled as A-1 through A-13 and B-1 to B-8.
The BVW is a small offset from the Bank and is delineated between flags B-2 and B-4, in addition to the wetland
created as part of the 2009 project, flags B-8 to B-12. Based on the size of the vegetation, it appears to be
maintained by mowing at least somewhat regularly. The predominant wetland vegetation observed within the
BVW includes sensitive fern (Onoclea sensibilis), wool grass (Scirpus cyperinus), red maple (Acer rubrum), and
Eastern hemlock (Tsuga canadensis).
Upon completion of the wetland assessment, we conclude that the wetland resources located west of the existing
buildings is are BVW and Bank, as defined in the WPA regulations at 310 CMR 10.55 and 310 CMR 10.54,
respectively.
Of note, the vegetated area between the constructed wetland replacement area and the stormwater
management wetland, there is a dominance of hydrophytic vegetation, including sensitive fern (Onoclea sensibilis)
and tear thumb (Persicaria sagittata). The area was thoroughly evaluated and checked for other indicators of
wetland hydrology and hydric soil, but was not found to have evidence of either. We concluded that the area is
not a wetland based on the lack of field evidence.
Conclusions
The BVW and Bank Resource Areas onsite are expected to serve the Interests of the WPA, as defined under 310
CMR 10.01(2), including Protection of Wildlife Habitat, Protection of Ground Water Supply, Prevention of
Pollution, and Storm Damage Prevention.

USE OF REPORT
1. GZA GeoEnvironmental, Inc. (GZA) has prepared this report on behalf of, and for the exclusive use of HERITAGE
SURVEYS, Inc. (“Client”) for the stated purpose(s) and location(s) identified in the report. Use of this report, in whole
or in part, at other locations, or for other purposes, may lead to inappropriate conclusions; and we do not accept any
responsibility for the consequences of such use(s). Further, reliance by any party not identified in the agreement, for
any use, without our prior written permission, shall be at that party’s risk, and without any liability to GZA.
STANDARD OF CARE
2. GZA’s findings and conclusions are based on the work conducted as part of the Scope of Services set forth in the Report
and/or proposal, and reflect our professional judgment. These findings and conclusions must be considered not as
scientific or engineering certainties, but rather as our professional opinions concerning the data gathered and
observations made during the course of our work. Conditions other than described in this report may be found at the
subject location(s).
3. GZA’s services were performed using the degree of skill and care ordinarily exercised by qualified professionals performing
the same type of services, at the same time, under similar conditions, at the same or a similar property. No warranty,
expressed or implied, is made.
LIMITS TO OBSERVATIONS
4. Natural resource characteristics are inherently variable. Biological community composition and diversity can be
affected by seasonal, annual or anthropogenic influences. In addition, soil conditions are reflective of subsurface geologic
materials, the composition and distribution of which vary spatially.
5. The observations described in this report were made on the dates referenced and under the conditions stated therein.
Conditions observed and reported by GZA reflect the conditions that could be reasonably observed based upon the visual
observations of surface conditions and/or a limited observation of subsurface conditions at the specific time of
observation. Such conditions are subject to environmental and circumstantial alteration and may not reflect conditions
observable at another time.
6. The conclusions and recommendations contained in this report are based upon the data obtained from a limited number
of surveys performed during the course of our work on the site, as described in the Report. There may be variations
between these surveys and other past or future surveys due to inherent environmental and circumstantial variability.
RELIANCE ON INFORMATION FROM OTHERS
7. Preparation of this Report may have relied upon information made available by Federal, state and local authorities;
and/or work products prepared by other professionals as specified in the report. Unless specifically stated, GZA did not
attempt to independently verify the accuracy or completeness of that information.
COMPLIANCE WITH REGULATIONS AND CODES
8. GZA’s services were performed to render an opinion on the presence and/or condition of natural resources as described
in the Report. Standards used to identify or assess these resources as well as regulatory jurisdiction, if any, are stated in
the Report. Standards for identification of jurisdictional resources and regulatory control over them may vary between

governmental agencies at Federal, state and local levels and are subject to change over time which may affect the
conclusions and findings of this report.
NEW INFORMATION
9. In the event that the Client or others authorized to use this report obtain information on environmental regulatory
compliance issues at the site not contained in this report, such information shall be brought to GZA's attention
forthwith. GZA will evaluate such information and, on the basis of this work, may modify the conclusions stated in this
report.
ADDITIONAL SERVICES
10. GZA recommends that we be retained to provide further investigation, if necessary, which would allow GZA to (1)
observe compliance with the concepts and recommendations contained herein; (2) evaluate whether the manner of
implementation creates a potential new finding; and (3) evaluate whether the manner of implementation affects or
changes the conditions on which our opinions were made.
