MassDOT Railroad Division located within the City of Northampton (fee).
Narrative
CPA Funding is requested to advance design of a multi-use trail that will connect the
town of Hatfield, which has no shared use trails, with the MassCentral Rail Trail and the
New Haven and Northampton Canal Greenway, to the 25% design phase. This will
provide what will soon be a continuous link from Boston to Northampton to New Haven
can both serve Hatfield and one of the most beautiful sections of the Connecticut River.
The 1.3 mile shared paved shared use path (with a short section shared with the
Connecticut River Greenway access driveway) will go from Damon Road (by 80 Damon
Road to 120 Elm Court, Hatfield at 100 Hatfield Road, Northampton). To the south this
connects to the Damon Road shared use path (currently under construction and to be
completed in 2024), which itself connects to the MassCentral Rail Trail. To the north it
connects to a network of small bicycle friendly streets. The project will separate
bicycles and pedestrians from the only road that serves the same destination and origin
(North King Street Routes 5 and 10), reducing the risk of crashes. Separation and
fencing between the shared use path and the MassDOT active rail road will be designed
in accordance with MassDOT standards.
The trail will be an asphalt trail ten feet wide with two foot shoulders. It will all comply
with the strictest ADA and AAB standards and be less than 5% grade along the trail and
less than 2% cross slope. It will include one long bridge and some smaller culverts. It
will include benches in locations that will provide dramatic views of both the
Connecticut River and the Holyoke Range. It will connect to the Damon Road and
MassCentral shared use paths, providing a continuous connection that will eventually
connect to Boston and New Haven and directly goes through and serves an
environmental justice neighborhood.
Using CPA and state grant funds, we have obtained full fee interest in all of the
properties over which the trail will pass, including land in the town of Hatfield. The City
formerly had only a 50% interest in the parcels, and this is an important step that the
City has been pursuing for decades that will allow construction to occur. CPA and state
grants achieved the 10% design stage milestone. This is a critical step in the formal
state design process to allow state funding for construction to begin to be programmed,
and to allow permitting and other milestone steps to advance. Work leading up to the
completed 10% design phase included an initial topographic survey, a feasibility study
with preliminary cost estimates of the path, meetings with MassDOT rail and highway
and the town of Hatfield, an initial feasibility assessment regarding environmental
permitting, a geotechnical assessment, construction cost estimate, layout, and
structural due diligence. The findings are summarized in VHB’s attached design memo
Connecticut River Greenway Trail 3
that provides an overview of design parameters, constraints, permitting needs, and
design next steps.
The project is included in the City’s Sustainable Northampton Comprehensive Plan and
its Open Space, Recreation, and Shared Use Plan. Both processes included extensive
community engagement and this project received strong support. When the City
acquired two parcels a decade ago where the trail will go, the deed and easement
specifically mentioned the future planned shared use trail, which City Council accepted
when they accepted that deed and easement. A reserved right for the trail is also
included in the City’s newest riverfront acquisitions.
The southern terminus of the trail, the City’s Connecticut River Greenway, is already
accessible and include accessible parking spaces (a/k/a “handicap;” parking). The entire
trail will meet all ADA and AAB standards and be less than 5% grade with benches, to
ensure that many populations with mobility disabilities can use the trail.
When complete, the trail will connect to the longest shared use path spine in the
Commonwealth (the MassCentral Rail Trail and connecting New Haven and
Northampton Canal Greenway. Second the trail has spectacular views of both the
Holyoke Range and the Connecticut River. Finally, the trail is well suited for short
journeys (e.g, residents of the environmental justice neighborhood wanting to take an
evening stroll) and long distance users (e.g., anything from travel to downtown
Northampton to travel all the way to New Haven).
CPA Criteria
The project meets several Community Preservation general criteria:
Serves more than one CPA program area
The project serves both Open Space and Recreation.
Contributes to the preservation of Northampton’s unique character, boosts the vitality of
the community, and enhances the quality of life for its residents
Addresses recommendations contained in the Sustainable Northampton comprehensive
plan and/or the Northampton Open Space, Recreation, and Mixed Use Trail Plan or is
consistent with other city-wide planning efforts that have received broad-based scrutiny
and input and can demonstrate wide community support
Multi-use paths were identified as a primary objective in the Open Space,
Recreation, and Mixed Use Trail Plan, so much so that the Plan’s name was
changed to include them. The Plan noted that “opportunities for new or
expanded connections to existing trail networks for alternative transportation,
walking, hiking, biking, cross-country skiing, and other recreational opportunities”
are priorities when considering sites for recreation. The Connecticut River
Greenway Trail was called out as a specific goal as well: “Extending a trail 1.5
miles from Damon Road or 1.3 miles from River Run Access Road to Elm Court in
Hatfield would dramatically open up multi-use trail opportunities. It would connect
Connecticut River Greenway Trail 4
a new town to the growing rail trail network and provide easy access to Hatfield’s
safe back roads for Northampton bicyclists. It would also be a spectacular trail
with great Connecticut River vistas and it would be anchored by the south by the
new greenway community boathouse park and on the north by the Connecticut
River Greenway parcel with frontage on the river.”
Serves under-served populations
Places high value on sustainable, ecologically responsible, energy-conserving structures,
locations, and materials; demonstrates that the project minimizes the ecological
footprint
The project will create additional connections for alternative modes of travel, and
provide new opportunities to bike and walk to shopping areas and the
downtown, potentially reducing vehicle trips.
Receives endorsement by community groups, municipal boards and/or departments and
City residents.
Leverages additional public and/or private funds, or demonstrates that other funding
sources are not readily available or sufficient
Demonstrates a high benefit/cost value
Multi-use trail projects have typically received tremendous public support in
Northampton, and this trail will be a very visible, highly traveled, scenic addition
to the trail network.
Can be implemented expeditiously and within budget
The project also meets many of the specific criteria for Open Space and Recreation
projects:
Open Space Criteria:
Provide opportunities for passive recreation and environmental education
Provide connections with existing non-motorized multi-use trails or potential trail
linkages
Preserve valuable surface water resources, including rivers, streams, lakes, ponds,
wetlands, buffer zones, vernal pools and riparian zones
Recreation Criteria:
Support multiple active and passive recreation uses;
Serve a significant number of residents;
Expand the range of recreational opportunities available to Northampton residents of
all ages
Enhance the appreciation of the natural world and its conservation
Contribute to the positive health status of its citizens
Benefit conservation and recreation initiatives
Connecticut River Greenway Trail 5
Maximize the utility of land already owned by Northampton (e.g. school property)
Promote the creative use of former railway, waterways and other corridors, including
connecting corridors, to create safe and healthful non-motorized transportation
and exercise opportunities
Incorporate environmentally friendly design and long-term maintenance

10%/Conceptual Design Memorandum
Project Overview
VHB has prepared the conceptual design submission for the third phase of the Connecticut River Greenway. This 1.57-
mile section of the greenway begins at the northerly terminus of the second phase (Project# 608236 Damon Road
currently under construction) at River Run/CT River Access Drive in the City of Northampton and ends at Hatfield
Road/Elm Court in the Town of Hatfield. This project will connect with the Mass Central Rail Trail/ Norwottuck Trail to
the south via the shared use path or greenway being constructed along Damon Road. The trail will traverse along the
River Run/CT River Access Drive northerly for approximately 0.27-miles and then transitioning to an off-road shared
use path (SUP) paralleling an active rail line to the west owned by the Massachusetts Department of Transportation
(MassDOT) and the Connecticut River to the east for
approximately 1.3 miles. The SUP will end in the
northern section of Northampton at Hatfield Road/
Elm Court. Where these two streets meet is the
municipal boundary between the two communities.
The Town of Hatfield voted to allow the City of
Northampton to advance the project at its annual
Town Meeting on May 9, 2023.
The alignment will traverse municipal (Northampton
and Hatfield), private, and state property owned by
MassDOT. Where the SUP crosses two private
properties, the City of Northampton has an existing
easement or has 50% ownership with rights to build a
multi-use trail. The northerly and southerly project
limits will intersect public ways. The project location is
presented in Figure 1. There is an existing parking area
owned by the city at the end of River Run/ CT River
Access Drive just under 600-feet east of the off-road
entrance. The northerly project terminus can
accommodate approximately three to four parking
spaces; however, the final lot design will be
coordinated with the Town of Hatfield as the design
advances.

Most of the project, or approximately 1.42-miles is in the City of Northampton with the balance or approximately 750-
feet in the Town of Hatfield. The City of Northampton is the lead community for the project design with input from
the Town of Hatfield on the terminus to the north. The city is currently working with the Town of Hatfield on a
memorandum of understanding outlining provisions for the trail access.
Within the wooded area, the SUP will parallel an active rail corridor owned by MassDOT (aka Knowledge Corridor) to
the west and the Connecticut River to the east. The proposed SUP will be offset 25-feet or more from the center line
of the railroad tracks and separated with a chain link fence. The fence will be a continuous 8-foot high tight mesh
chain link fence (with 6” gap at the bottom for wildlife passage) and will be installed to prevent users from straying
into the area while allowing wildlife to pass.
Construction access will be required into the railroad right-of-way. Appropriate measures are required to access this
area such as, safety education/training, protective equipment (i.e.. hard hat, boots, and high visibility vest), railroad
flaggers, and insurance.
Proposed Alignment
River Run/CT River Access Drive
River Run/CT River Access Drive is a dead-end shared access drive for the River Run Apartments, a public city parking
area with access to the Connecticut River Greenway
Riverfront Park and other land parcels. This access
drive provides travel in two directions and varies in
width between 16.5 and 22.5 feet. The conceptual
improvements proposed for this roadway is being
shared with MassDOT for discussion purposes, as it
was a last-minute request by MassDOT to extend the
project to a public access roadway (Damon Road).
While the City believes they have public access via
this street, the concept presented in the plans
minimizes impacts to the condominium property to
the east. The City believes that impacting the grass
area across the condominium frontage will be
problematic. It is noted that survey is ongoing for Figure 2 River Run/CT River Access Drive - Northampton

area and the design can be updated once MassDOT reviews. The current base plan combines various survey and
LiDAR data to depict the improvements, adjustments will need to be made even if the conceptual cross section is
accepted.
A 10-foot-wide SUP is proposed along the east side of River Run/CT River Access Drive from the HAWK crossing on
Damon Road (Project# 608236) northerly approximately 300 feet along with the continuation of a 5.5-foot sidewalk on
the west side. At this point the SUP will stop and users will transition into the roadway using a new raised crosswalk
supplemented with Rectangular Rapid Flashing Beacon. At this point pedestrians will be able to use the proposed
sidewalk on the westerly side of the roadway and bicyclists will share the roadway with vehicular traffic using 5-foot
advisory bike lanes in each direction. A shared 10-foot center travel lane will be provided in this area for
approximately 1,200 feet until the off-road SUP. At the off-road SUP, the remaining 600 feet of River Run/CT River
Access Drive will continue as a two-lane drive to the City of Northampton parking area for the Connecticut River
Greenway Riverfront Park.
Wooded Area Section: River Run/CT River Access Drive to Hatfield Road (Northampton)/Elm Court (Hatfield)
The off-road SUP will begin in the wooded area along the northerly portion of River Run/CT River Access Drive and is
proposed to continue for approximately 1.3 miles as a hot mix asphalt 10-foot wide SUP. There are two small sections
where this will deviate in width and/or material type. One is at a wetland area in southern portion of the project where
a 14-foot-wide timber boardwalk is proposed for 385 feet on piles. The other area is very northern portion of the
project where an 8-foot section of path will
likely be needed to lessen the construction costs
of building within the embankment where a
retaining wall structure could encroach into a
small section of flood zone. In this section the
alignment will meander through the woods and
parallel the rail corridor maintaining at least a
25-foot offset. The previous alignment shared
with MassDOT (scoping meeting) carried an 18-
foot offset but was last modified following a site
walk on March 25, 2023 with municipal and
state officials to maximize the separation of the
SUP from the railroad tracks. MassDOT Rail and
their consultant AECOM indicated that there

must be a minimum of 25 feet of separation from the centerline of the tracks with a new 8-foot-high chain link fence.
With the adjusted offset, the proposed SUP now traverses over steep embankments down to the Connecticut River
increasing the needs for retaining wall type structures to support the SUP. The northerly section of the alignment will
transition to an area completely buffered from the railroad right-of-way by a combination of vegetation and elevation
change, this is for approximately 1,200 feet.
Trail Design Criteria
The design criteria used is from the 2012 AASHTO Guide for the Development of Bicycle Facilities and the MassDOT
Project Development and Design Guide (PDDG). The design is summarized as follows:
Design speed:
A design speed of 20 MPH was chosen as it is the minimum preferred design speed in the PDDG for a shared use
path.
Trail/ Shoulder Width
The minimum recommended path width of 10-feet with 2-foot shoulders is provided to limit the impacts to
environmental resources and forested areas. There is an area between STA 56+00 to STA 58+00 where the SUP may
need to be reduced from 10-feet to 8-feet in width to avoid the need of an extensive retaining wall system that could
impact the flood zone. There are 3-foot shoulders proposed in locations where railing or fence is proposed parallel the
trail. A detailed explanation of the environmental resource areas is provided in the environmental impact section of
this memo. The minimum widths will also help to reduce the cost of the path by using less materials, reducing the
amount of clearing and grubbing, reducing height of retaining walls, and the width of boardwalks and structures. The
shared use path is proposed to be hot mix asphalt except where the trail is carried by the timber boardwalk over the
wetlands. The shoulders are proposed to be dense graded crushed stone with grass beyond them where it can be
established.

Horizontal Alignment
Figure 4, based on Table 5-2 from
AASHTO, the minimum radius is 74-
feet for a 20 MPH design speed. This
minimum curve radius criteria are met
for the entire path.
Figure 4 – Design Speeds with Minimum Radius
Vertical Alignment
The maximum grade without providing level landing areas is 5% slope. The proposed grades for the trail have all been
designed to be 4.5% or less. The vertical curves have been designed to exceed stopping sight distance (SSD)
requirements in all locations. The distances are shown on the proposed profile.
Cross Slope:
A 1.5% cross slope with a construction tolerance of 0.5% was used in one direction; the proposed slope meets the
maximum 2% for pedestrian users and will be sloped toward the river.
Environmental Impacts
The proposed trail runs in and out of an environmentally sensitive area with portions of the alignment within,
riverfront area, a wetland, and priority and estimated habitat. The SUP alignment required a balance of minimizing
impacts to these areas while providing a minimum offset from the active rail tracks.

Wetlands
The project has been designed to minimize impacts to wetlands. There is one location where the SUP will traverse a
wetland that is unavoidable. The wetland area appears to have been created from runoff from the railroad right-of-
way. This area is in the southerly portion of the project where the SUP is in a wooded area from STA 12+00 to STA
15+85. Impacts resulting from filling this wetland for an at-grade path are estimated to exceed 5,000 SF. Adjusting the
alignment in this area would either push the SUP closer to
the rail or out of the City of Northampton easement and
onto private property. Therefore, a 385-foot raised
boardwalk structure is proposed supported by helical piles.
This proposed work significantly reduces the wetland
impacts to an estimated 1,625 SF since only the footings of
the raised boardwalk are considered an impact.
An erosion and sedimentation control program will be
developed to minimize secondary impacts during
construction. Areas of temporary impacts will be seeded
with a native wetland seed mix. Mitigation for permanent
impact to wetlands will be provided in the form of wetland
replication at a ratio of 1:1.

Estimated and Priority Habitats
The SUP will travel through two areas
identified by the Nation Heritage and
Endangered Species Program (NHESP).
One is a priority habitat PH 2084 and the
other is an estimated habitat of rare
wildlife EH 1319. A consultation letter
request will be sent to the NHESP during
the 25% design to identify any
endangered species or wildlife that may
be within the project area. The current
alignment was designed to minimize
encroachments and avoid the removal of
large trees in this area. This was a
challenge due to maintaining the
required 25-foot offset from the rail and
steep embankments and ravines leading
down to the Connecticut River. Figure 6
depicts the SUP through these areas.
Floodplain and Floodway
There is floodplain located near the
project limits along the Connecticut
River. The entire length of the proposed
alignment falls outside Zone AE. There is
an area between STA 56+00 to STA
58+00 where the SUP is near Zone AE. A
reduction of path width from 10-feet to 8-feet in this area may be needed to avoid impacts to the flood zone with
structures for path support. Hydrologic/ hydraulic analyses will not be necessary for this project. Any fill proposed is
anticipated to be above or outside the limits of the 100-year floodplain elevation.

Trees
There are trees that are proposed to be removed since most of the SUP is located within a wooded area. VHB walked
the proposed trail alignment with City, Town and MassDOT representatives to review the trail alignment in a manner
that lessened tree impacts. As the design advances tree impacts will be quantified; however, most of the trees to be
removed are along the northerly sections where cut is the greatest.
Article 97
During the project scoping checklist meeting in February 2023, MassDOT officials noted the following four Article 97
properties could be impacted. An Open Space Resources map of these areas is presented in Figure 7 on the next
page.
1. CT River Greenway Park (City of Northampton)
2. CT River Conservation Area (City of Northampton)
3. Public/Private Conservation (Cahillane James and Skibiski John F)
4. Hatfield Line Conservation Area (City of Northampton)
The City of Northampton indicated that they do not believe the project will be subject to Article 97 impacts. Following
the scoping checklist meeting, the city sent a letter to the Public Lands Preservation Act review team outlining reasons
why they believe that this project is not a conversion of land subject to Article 97, Section 4(f), or Section 6(f). A copy
of this correspondence attached and dated February 25, 2023.
It is noted that the proposed alignment does not fall within the CT River Greenway Park (City of Northampton) or the
CT River Conservation Area (City of Northampton). Therefore, there are no Article 97 impacts to this land.
The city has 50% ownership in the Public/Private Conservation (Cahillane James and Skibiski John F) land through its
Conservation Commission for administration, control, and maintenance. Details of this are also in the correspondence
attached and dated February 25, 2023.
The Hatfield Conservation area (City of Northampton) is separated and on the opposite the railroad right-of-way.
Therefore, this area will not be impacted by the project.
Archeological
The project is located just east of the Hatfield Street roundabout project (MassDOT Project #612988) that was just
recently stopped due to artifacts founds in and within that project area. During the scoping checklist meeting for this
trail project, MassDOT noted that they would investigate if this would be applicable.

Hazardous Materials Screening
Based on a high-level review of the
MassDEP Searchable Sites database,
two disposal sites were identified
within 500-feet of the shared use path
that have the potential to impact
environmental conditions (i.e., soil
and/or groundwater) within the
Project Area.
RTN 1-21372 (400 feet West of the
Project): In August 2021, non-
aqueous phase liquid (NAPL) was
identified on soil at 188 North King
Street. The disposal site achieved
closure through the submittal of a
Permanent Solution Statement in
October 2021 and residual
concentrations of petroleum
constituents remain in soil and
groundwater. Groundwater flow
direction was not documented but
presumably flows towards the
Connecticut River and the Project.
RTN 1-809 (400 feet West of the
Project): In June 1990, a release of
petroleum-related constituents was
identified during the removal of three
underground storage tanks. The
release achieved closure through the
submittal of a Class A-2 Response Action Outcome (RAO) Statement in October 1990; however, residual
concentrations of petroleum constituents remain in soil and groundwater. Groundwater flow direction was not
determined as part of response actions but may potentially flow towards the Site.

Both RTNs could affect groundwater within the Project area. If groundwater is not expected to be encountered during
construction, then these sites may be less of a concern for the Project.
In addition to the disposal sites above, the shared use path will be constructed in accordance with MassDEP Best
Management Practices for Controlling Exposure to Soil During the Development of Rail Trails in areas of concern in
close proximity to the railroad right-of-way These guidelines assist with managing typical residual railroad
contaminants during construction when working within rights-of-way.
Right of Way
There are eight (8) property owners within the project area consisting of both public and private entities. The River
Run/CT River Access Drive access drive property is privately owned (4 separate property owners) and the city has an
existing easement giving them public access rights today. There is also a 30-foot easement for utilities and access.
Details of this easement are noted in the documents provided in the attached letter dated February 25, 2023. The
public currently uses this drive to access the parking area for the Connecticut River Greenway Riverfront Park (owned
by the city) and the Northampton Rowing Community.
Once the greenway transitions back to a SUP from River
Run/CT River Access Drive and enters the wooded area it
will traverse a private parcel on an existing 20-foot
easement the city has for a path providing access to the
Connecticut River Conservation area. This is also
described in the attachment dated February 25, 2023.
From that point the path will utilize property in the city
owned by MassDOT adjacent in and adjacent to the
railroad right-of-way, also owned by MassDOT.
Approximately half of the greenway is proposed in this
area. An easement and/or license agreement will be
needed from MassDOT for construction and long-term
maintenance.
North of the land owned by MassDOT the SUP is proposed two parcels of land one entirely in the city and one in both
Northampton and Hatfield. The city has 50% ownership of these parcels with John Skibiski Realty with rights to build,
maintain, repair, and replace a rail trail or multi-use trail. Correspondence from the city is attached and dated February
25, 2023, which outlines this with supporting documentation. The city is currently pursuing purchasing the remaining

50% interests on this land as part of a broader conservation project to protect 25 acres along the Connecticut River.
The parcel of land where the SUP will end at Hatfield Road and is geographically located within the city but is owned
by the Town of Hatfield.
Structural Considerations
There are several proposed structures as part of this alignment that will
be required to support the path due to the steep embankments and
ravines easterly to the Connecticut River. The following discusses
potential options that will continue to be reviewed.
Boardwalk
A 385-foot boardwalk is proposed between STA 12+00 and STA 15+5 to
minimize impacts to an existing wetland. A 14-foot-wide timber structure
with wood railing is proposed on helical piles if subsurface conditions are
favorable following the geotechnical analysis. If determine unfavorable,
the path alignment would need to be adjusted or could require fill that
will exceed 5,000 square feet of wetland impacts and require replication.
Retaining Walls vs. Bridges
A 475-foot retaining wall is proposed between STA 16+50 and STA
20+75 to support the path. This is unavoidable since the alignment is
constrained between the steep embankment toward the Connecticut River and maintaining a 25-foot offset from the
centerline of the railroad tracks.
Bridges were considered in two locations. One is between STA 38+50 to STA 40+75. The second is in the area in the
area between STA 44+50 to STA 45+50. At Station 38+50 to 40+75, the bridge in this area would require a span of
approximately 200-feet and at least one mid span abutment. Due to the adjacent terrain, which includes a steep
embankment and ravine, this bridge would be very costly if not impossible to construct. Therefore, a retaining wall
structure or earth support system is proposed to support the path along an extension of the top of slope. This will
support the path and provide stabilization to the eroding side slope which has already been partially addressed in the
past with large rip rap and stones. See earth support system section below. At Station 44+50 to 45+50, there appears
to be erosion in this area caused by drainage from the railroad, as this is a local low point. The design improvements
will include adding a culvert, flared end sections, and stone for pipe ends to collect the drainage and outlet it properly
to avoid any future erosion. The path will continue over the culvert.

At STA 58+00 and STA 63+50, there is an embankment with steep side slopes between the railroad and the adjacent
wooded area. The embankment is along the railroad right-of-way and appears to contain soils that were excavated
when the rail corridor was cleared and pushed to the side. This is the most difficult section to maintain an AAB/ADA
compliant grade due to the existing grades. The proposed alignment will cut down a substantial portion of the hill to
create a level area to construct the path and the existing steep embankment will be proposed to be stabilized. . There
were two other alignments reviewed in this area and what is proposed is a balance between constructability and
having the need for multiple structures. The following summarizes these alternative alignments.
· One alignment reviewed was located on the westerly side of the embankment, within a primarily level portion
of the rail corridor that would require minimal if any structures. However, this was dismissed as it was within
the MassDOT required 25-foot offset area from the railroad tracks.
· The second alignment was located along the easterly side of the embankment where a significant side slope
exists with some short sections of level landing areas. This alternative would require retaining walls not only
along the easterly side to support the path but a wall on the westerly side to hold back the hill. This was
dismissed due to the need for more structures and a higher level of constructability due to the surrounding
terrain.
There is also a small retaining wall structure that will be needed at the northerly end of the project near adjacent to
the railroad bridge near Hatfield Road. This would only be necessary if the city and town decide to provide a small trail
head parking area for 3 to 4 vehicles. This parking lot requires additional coordination with the Town once the
alignment is reviewed with MassDOT. The wall would be required to support a small portion of the embankment to
accommodate the trail access and parking area.
A geotechnical investigation that will include soil borings and slope stability analysis to determine the appropriate
earth support structures and if a boardwalk is feasible through the existing wetland in the south. Please reference the
preliminary geotechnical study that is attached for additional details.
Earth Support Systems
There are three (3) primary types of earth support systems currently being considered that will depend upon findings
from the geotechnical investigations and analysis. This includes sheet pile, soldier pile with lagging, and a
prefabricated modular wall.
Sheet pile walls are being considered due to the limited or no horizontal footprint along the Connecticut River side of
the alignment. These walls would be driven into the ground that will create a continuous wall with a concrete cap and
railing. This type of structure would also help to stabilize any eroding side slopes that may need to be addressed in

the near future independent of this project. This type of wall would not be used if there are subsurface boulders
identified, in addition the depth of any underground
utilities or culverts would need to be reviewed.
Another wall alternative being considered is soldier pile
and lagging type wall. This is being considered in areas
where a sheet pile wall may not be feasible and where
deep foundations are needed. These are more costly than
sheet pile walls but can serve a dual purpose of temporary
and permanent support walls.
The third type of wall being considered is the conventional
prefabricated wall systems. Theses would be used in areas
where only small walls are being used that do not require
deep foundations. This would be applicable to a situation
at the northerly trailhead to hold back a small area of
embankment to accommodate a parking stall if needed.
Hydrologic/Hydraulic Factors:
There are no waterways that will be crossed by the
proposed alignment. There will only be areas of runoff
from the railroad right-of-way corridor (east side of the
tracks) that will need to be piped under the path at isolated
low areas.
Aesthetics:
Given the surrounding environment, aesthetics will be less of a consideration on the structural elements of this project.
Earth support systems will be primarily facing a wooded area along the Connecticut River, so aesthetics is less of a
concern for these structures. Railings will be provided along these structures where needed.
High-Level Construction Cost Estimate
Estimated or order of magnitude costs to construct the project described above has been prepared using high-level
pricing per linear foot and other unit cost estimates. Prices are obtained from the MassDOT Weighted Average Bid
Application (WABA) online and other projects that the VHB team has designed. Additional design, subsurface soil
investigations, and permitting are necessary before a construction cost estimate can be refined; therefore,

contingencies and cost escalations have been applied. Also, given the path location (in the woods with uneven terrain)
and the need for construction equipment to access (or work adjacent to) the railroad right-of-way the costs to
construct this trail could be a premium. Railroad flaggers, insurance, time of day work restrictions (to avoid rail
activity), or environmental considerations are also other factors that will need to be confirmed.
A conceptual construction cost estimate has been attached to this memo. The estimated construction cost is
approximately $12,000,000.00.
Conclusion and Next Steps
The proposed alignment was prepared based on various adjustments to minimize impacts to adjacent resource areas,
large trees, provide a safe buffer to the active rail corridor, avoid steep embankments where possible and provide
connections to public ways in both communities. These adjustments were made following discussions with the City,
Town and MassDOT and this alignment was identified that meets the project goals.
The next steps to advance this project include performing the subsurface geotechnical investigations and finalize the
River Run/ CT River Access Drive design. To expedite the geotechnical investigations, VHB has also submitted a draft
boring location plan to solicit feedback, get consensus on the locations versus the proposed alignment and discuss
accessibility to perform the work.

Re. Phase I Geotechnical Services
Proposed CT River Greenway
Northampton, Massachusetts
LGCI Project No. 2325-Rev.3
Dear Mr. Chase:
Lahlaf Geotechnical Consulting, Inc. (LGCI) has completed a preliminary geotechnical study for
the proposed shared use path (Connecticut (CT) River Greenway) in Northampton, Massachusetts.
This letter report presents the results of our preliminary study.
We performed our services in general accordance with our proposal No. 23022-Rev. 1 dated May
21, 2023, and in accordance with the terms and conditions of the Subconsultant Authorization issued by Vanasse Hangen Brustlin, Inc. (VHB) dated June 16, 2023.
1. Purpose
The purpose of the services described in this letter report (Phase I services) was select boring
locations, assist VHB with a boring location plan, coordinate with the drilling subcontractor about
methods to mobilize to the proposed wall locations to perform borings, and prepare this letter
report describing our technical approach and our opinions about feasible retaining wall types.
Phase II services, which are not part of this letter report, will consist of engaging a drilling
subcontractor and performing soil borings for the proposed boardwalk and for the easily accessible
locations along the proposed retaining walls. Phase III of our services, not included in the scope
of the proposal listed above, will consist of performing soil borings at locations not completed in
Phase II. Field observations will be needed to confirm the findings in this letter.
2. Site Description
Our understanding of the proposed construction is based on our discussions with you on the
following drawings:

• “CT River Greenway, Northampton,” (Site Plan) Project File No. 612777 (3 sheets), provided
to LGCI by VHB via e-mail on May 16, 2023.
• “Connecticut River Greenway, Northampton, MA, Draft Borung Plans, MassDOT Project
#612777,” (Boring Plans) prepared by VHB, dated December 20, 2022, and provided to LGCI
by VHB via e-mail on June 14, 2023.
Based on the Site Plan and the Boring Plans the site is accessible from a narrow, paved road (River
Run) extending parallel to the northern side of Interstate I-91 and starting at Damon Road in
Northampton, Massachusetts as shown in Figure 1 (based on the Boring Plans and an aerial view
of the site from google.com/maps). The proposed greenway will be located on the eastern side of
an existing, in-service set of railroad tracks and will extend about 7,700 feet from near the
intersection of River Run and Damon Road to Hatfield Road near the boundary line between the
Towns of Northampton and Hatfield. Based on the Site Plan, the alignment of the proposed shared
use path will generally clear wetlands except for an approximate combined 800-foot section on the
southern side near the intersection of Damon Road and River Run where the proposed shared use
path will be in a wetland or a wetland buffer zone.

Alignment of Proposed
Shared Use Path

Northampton, Massachusetts
LGCI Project No. 2325-Rev. 3
Page 3 of 13
The alignment of the proposed shared use path will traverse wooded areas and will be located near
the top or middle of steep slopes.
Access to the alignment of the proposed shared use path will be through River Run on the southern
side and through Hatfield Road on the northern side. Locations in the middle of the alignment of
the proposed shared use path will be through the railroad maintenance road on the western side of
the railroad and will require coordination with the railroad owner and/or operator. Access to the
maintenance road appears to be available via Damon Road.
3. Project Description
Based on the Site Plan, the proposed shared use path will extend from Sta. 09+00 on the southern
side near the intersection of Riven Run and Damon Road and Sta. 77+00 near Hatfield Road. The
proposed shared use path will consist of a two -lane 10-foot, paved path with two (2) 2-foot
shoulders (one shoulder on each side).
We understand that the proposed path will require variable amounts of cuts and fill along its
alignment. The magnitude of the cuts and fill is not known at this time as the grading of the
proposed shared use path is not finalized.
We understand that the proposed greenway could include the following structures:
• One (1) boardwalk between Sta. 12+00 to Sta. 15+85.
• Two (2) retaining walls between Sta. 16+50 and Sta. 20+75, and between Sta. 38+50 and Sta.
40+75.
• A slope or possibly a retaining wall between Sta. 58+00 and 63+50.
• A short retaining wall to provide parking near the Hatfield town line.
• One (1) pipe or box culvert near Sta. 45+00.
4. Proposed Exploration Program
LGCI discussed the project with representatives of VHB and our drilling subcontractor. Based on
the length of the proposed structures, LGCI recommends a subsurface explorations program
consisting of nineteen (19) soil borings and two (2) test pits as follows:
• Four (4) borings (B-1 to B-4) for the proposed boardwalk. These borings will require access
through wetlands. VHB indicated to us that the borings are exempt from requiring an Order
of Conditions from the location Conservation Commission. Access to the boring locations will
require tree and brush clearing over a path about 12 feet wide and possibly mats or other means
to reduce the potential for impacting the wetlands. We understand that the portion of the
proposed shared use path between Sta. 09+00 and about Sta. 17+00, including the proposed
boardwalk, is located within a City of Northampton easement. The drilling subcontractor will
exercise care moving between borings in this area. The drilling subcontractor will lay about 10
feet of hay bales or a 10-foot straw wattle on the lower side at each boring location within the
Phase I Geotechnical Services
Proposed CT River Greenway

wetlands. At the end of drilling the hay will be spread over the area and the area will be seeded
with a mixture of upland vegetation seeds.
• Five (5) borings (B-5 to B-9) for the proposed retaining wall between Sta. 16+50 and Sta.
20+75. Boring B-5 could be accessed from the City of Northampton’s easement and will
require tree clearing outside of the easement. The tree clearing will require authorization from
the private property owner. Borings B-6 to B-9 will be accessed from the railroad maintenance
road and will require crossing the railroad.
• Four (4) borings (B-10 to B-13) for the proposed retaining wall between Sta. 38+50 and Sta.
40+75. The borings will be accessed from the railroad maintenance road and will require
crossing the railroad.
• Boring B-14 for the proposed pipe or box culvert. This boring will be accessed from the
railroad maintenance road and will require crossing the railroad.
• Four (4) borings (B-15 to B-18) for the proposed retaining wall between Sta. 58+00 and 63+50.
Borings B-15 and B-16 will be accessed from the railroad maintenance road and will require
crossing the railroad. Borings B-17 and B-18 will be accessible through a dirt path starting at
Hatfield Road.
• Two (2) tests pits (TP-1 and TP-2) for the proposed retaining wall between Sta. 58+00 and
63+50. The test pits will be accessible through a dirt path starting at Hatfield Road.
• One (1) boring (B-19) for the proposed short retaining wall near the Hatfield town line. The
test pits will be accessible through a dirt path starting at Hatfield Road
The borings listed above that will be accessed from the railroad’s maintenance road and that will
require crossing the railroad tracks will require a permit from the railroad owner/operator, and
flaggers and railroad liability insurance.
5. Impact Mitigation
Our drilling and excavation subcontractors will exercise care while mobilizing the drilling and
excavation equipment between exploration locations. Most of our explorations will be clear of
resource areas, i.e., are clear of wetlands and the 100-foot buffer zone of wetlands.
Our borings B-1 to B-8 and B-11 will be located within the buffer zone of wetlands. Our drilling
subcontractor will exercise care while mobilizing the drilling equipment between exploration
locations and will only cut trees or branches where necessary. Our drilling subcontractor will use
a chain saw to cut small trees less than about 6 inches in diameter. We will generally avoid cutting
larger trees where possible. Where trees are cut, the trees will be moved to the side of the cut path
or work area.

The drill rig typically leaves little or no ruts on dry, firm surfaces. In soft areas of the sites, we
will plan our entry paths carefully to limit the amount of turning required which helps to limit the
formation of ruts. In soft ground, the rig may leave small ruts. In our experience, trying to bring
in new soil to fill minor ruts can cause more damage to the area.
During drilling, we will use a 10-foot length of straw wattles or hay bales on the lower side of the
work area. After completion of drilling, the drilling subcontractor will spread an upland seed mix
over the areas disturbed by the drill rig tracks. We have used similar seed mix on other projects
with good results.
6. Exploration Equipment
The drilling subcontractor will use a Mobile B-48 rig or equivalent. We have included below a
photograph of a typical drill rig.
The excavation subcontractor will use a small excavator (Kubota KX 080-4 or Komatsu PC-120,
or equivalent). We have included below a photograph of a typical excavator.

7. Proposed Exploration Procedures
The borings will generally be advanced in soil using cased wash-boring techniques to the depths
listed in the Boring Plans. Cased borings consist of driving a 3- to 4- diameter hollow casing into
the ground and cleaning the soil from within the casing using a rotary drill bit. The soil cuttings
are removed from the casing using water or drilling fluid injected into the borehole at the bottom
of the roller bit. The water or fluid is collected at the top of the casing (above the ground surface)
in a tub where the soil cuttings settle, and the water or fluid is re-circulated. If drilling fluid other
than water is used to keep the boreholes open, the drillers will use a biodegradable bentonite mixed
with water. We have assumed that a source of water will be made available to the drilling
subcontractor.
Standard Penetration Tests (SPTs) will be performed in each boring in general accordance with
ASTM Method D-1586. The test consists of driving a standard 2-inch outside diameter split barrel
sampler 24 inches into the soil using a 140-pound hammer falling freely a distance of 30 inches
onto an anvil at the top of the drill rods. After 6 inches of penetration, the number of blows required
to drive the sampler the next 12 inches is recorded as the standard penetration resistance, N-value.
The SPT sampler will be inserted through the casing to perform the test at each sampling depth,
before advancing the casing to the next depth. Sampling intervals are generally 5 feet from the
top of one sample to the top of the next sample.
After completion of each boring, the borehole will be backfilled with the drill cuttings and topped
off with sand. If we observe evidence of contamination, we will halt the drilling and notify you.
The drilling subcontractor can typically complete one to two borings per day, depending on the
difficulty of accessing each boring location.
Test pits are excavated to depths of up to 10 feet or to refusal, whichever occurs first. At the end
of each test pit, the excavated material is placed back in the excavation in 18- to 24-inch lifts and
is tamped with the excavator bucket. Our test pits will be performed off of the footpaths in the
woods.

8. Protecting Existing Railroad Tracks
Based on the Boring Plans, we understand that the distance from the nearest track to the centerline
of the proposed shared use path will be about 30 feet, i.e., about 24 feet from the edge of the
proposed shared use path. Assuming an approximate 4-foot work zone, the disturbed area for the
proposed construction will extend to within about 20 feet of the existing railroad tracks.
To reduce the potential of undermining the railroad tracks, we recommend that excavations not
extend deeper than a line starting 5 feet laterally from the nearest rail, inclined at a slope of 2H:1V,
and extending downward and outward. Where excavations must extend beneath the 2H:1V line,
a temporary support of excavation (SOE) system should be provided. Likewise, if the permanent
conditions require grades that are deeper than the 2H:1V line, permanent retaining walls should be
provided.
9. Retaining Walls and Temporary Support of Excavation Systems
The types and heights of the proposed retaining walls are not established at this time. The proposed
retaining wall types should be ones that reduce impact to resource areas and to the existing railroad
tracks.
We have listed below several types of retaining walls that could be used for the temporary
condition and/or the permanent condition, including modular walls, mechanically stabilized
(MSE) walls, cantilever concrete walls, masonry gravity walls, sheet pile walls, soldier
pile/micropile and lagging walls, and spoil nail walls. We have listed the advantages and
disadvantages of each type.
Modular Walls – Modular walls consist of concrete blocks of varying sizes that are stacked on top
of each other to retain the ground. The concrete blocks could be solid or hollow and filled with
crushed stone. The wall face is typically tapered and is available in a variety of colors and textures.
The back of the wall is typically backfilled with crushed stone or soil. Modular walls can be
constructed to heights exceeding 30 feet. After the subgrade is prepared, modular walls are
generally quick to construct. No concrete testing is required in the field as the blocks are precast
in the manufacturing plant and transported to the site. Modular walls are flexible and can
accommodate more settlement than concrete cantilever and stone masonry gravity walls. Modular
wall block could be large and heavy. Transport of the blocks to the site may be difficult.
Moreover, a large crane or excavator is required to handle the blocks at the construction site.
Where the site is narrow and site access is difficult, the use of modular walls may be challenging.
Construction of modular block walls requires an excavation that is typically 0.5 to 0.6 times the
height of the wall for a horizontal backfill at the top of the wall. Accordingly, the construction of
this type of wall where the wall is less than 24 feet from the nearest rail may require the installation
of a separate SOE system. Modular walls are proprietary and are typically designed by a registered
professional engineer engaged by the contractor.

Modular Wall Elements Before Filling with Crushed Stone
MSE Walls – MSE walls are composed of a concrete facing and a reinforced zone. The concrete
facing is typically small concrete blocks. The reinforced zone consists of soil reinforced with a
geosynthetic (typically a geogrid). MSE walls can be constructed to heights exceeding 30 feet.
The geogrid is placed at regular, vertical intervals over the height of the wall with lifts of soil
placed and compacted between geogrid layers. MSE wall concrete blocks are available with a
variety of colors and textures. MSE wall are generally considered more economical than concrete
cantilever and stone masonry gravity walls.
MSE Wall Under Construction
Phase I Geotechnical Services
Proposed CT River Greenway
Northampton, Massachusetts
LGCI Project No. 2325-Rev. 3
Page 9 of 13
MSE wall are generally flexible and can tolerate more settlement than most of the other wall types.
The construction of MSE walls requires a rigorous quality assurance program as the geogrid needs
to be placed horizontally, taught, and without folds and creases. The geogrid is typically 0.7 to
0.8 times the height of the wall for a horizontal backfill at the top of the wall. Accordingly, the
construction of this type of wall where the wall is less than 24 feet from the nearest rail may require
the installation of a separate SOE system. MSE walls are proprietary and are typically designed by
a registered professional engineer engaged by the contractor.
Cantilever Concrete Walls – Cantilever concrete retaining walls are L-shaped walls with a base
and stem made of reinforced concrete. Soil is placed and compacted on top of the base to increase
the weight of the wall. Cantilever concrete retaining walls are generally economically constructed
to heights of about 15 feet but can be constructed to heights of up to 20 feet. Higher walls require
tieback anchors. Cantilever concrete retaining walls are not as easy to construct as other types of
walls as they require erecting formwork. Also, cantilever concrete retaining walls are not very
tolerant to settlement and tend to be more costly than other types of walls. Construction of
cantilever concrete walls requires an excavation that is typically 0.5 to 0.6 times the height of the
wall for a horizontal backfill at the top of the wall. Accordingly, the construction of this type of
wall where the wall is less than 24 feet from the nearest rail may require the installation of a
separate SOE system.
Cantilever Concrete Wall Under Construction
Masonry Gravity Walls – A masonry gravity wall consists of a tapered, mortared, stone wall
constructed on a cemented stone or concrete foundation. Typically, the wall has a concrete cap at
the top. The wall is rigid and is not tolerant to settlement. Construction of masonry gravity walls
require an excavation that is typically 0.5 to 0.6 times the height of the wall for a horizontal backfill
at the top of the wall. Accordingly, the construction of this type of wall where the wall is less than
24 feet from the nearest rail may require the installation of a separate SOE system.

Sheet Pile Walls – Sheet pile walls are constructed by driving thin, prefabricated, interlocking steel
elements into the ground. Sheet pile walls are designed as cantilever walls and are generally driven
into the ground a length ranging between 1.5 and 2 times the exposed height. Sheet pile walls are
considered flexible walls and can tolerate large lateral deflections. Sheet pile walls could be
installed to heights of up to 15 feet. Higher walls require tiebacks or bracing with walers.

Sheet pile walls have a small footprint and can economically be installed as a support of excavation
system. Sheet pile walls could also be used as permanent retaining walls. Where the look of the
sheet pile wall is not pleasing, concrete panel facing could be hung on the sheet piles to provide a
concrete facing with a more desirable appearance. Sheet pile walls cannot be installed in ground
that is very dense or that contains boulders. If feasible, sheet pile walls would provide a suitable
option for the proposed retaining walls at the site.
Soldier Pile and Lagging Walls – Like sheet pile walls, soldier pile and lagging walls are
constructed by driving soldier piles (typically an H-piles) into the ground at 6- to 8-foot intervals
and filling the space between the soldier piles with wood or concrete lagging that is installed from
the top to the bottom (top-down construction) of the excavation as the excavation proceeds. The
lagging is placed behind the soldier pile flanges. Where the ground contains obstructions, the
soldier pile is installed by drilling a hole, installing the soldier pile, and placing concrete in the
annular space around the soldier pile up to the excavation (dredge) depth. Soldier pile and lagging
walls could be installed to heights of up to 15 feet. Higher walls require tiebacks o r bracing with
walers. Soldier pile and lagging walls have a small footprint and can economically be installed as
a support of excavation system. Soldier pile and lagging walls could also be used as permanent
retaining walls. Concrete panel facing could be hung on the sheet piles to provide a concrete facing
with a more desirable appearance. Where space does not allow for the mobilization of a large
machine to install the soldier piles, drilled micropiles could be used. The micropiles would need
to be outfitted with welded brackets to hold the lagging in place. If needed to increase stiffness,
the micropiles could be doubled (micropiles inside of micropiles).
Installation of Micropiles for Micropile and Lagging Wall
Soil Nail Walls – Soil nail walls are installed by drilling steel elements (nails) into the ground at
angles ranging between 15 and 20 degrees from the horizontal at regular intervals, and spraying
shotcrete of the exposed near-vertical face of the ground to be supported. The soil nails are
Phase I Geotechnical Services
Proposed CT River Greenway
Northampton, Massachusetts
LGCI Project No. 2325-Rev. 3
Page 12 of 13
installed in holes up to 6 inches in diameter that are filled with cement grout. The shotcrete is
reinforced with a steel mesh and serves as a wall facing.
Construction of a Soil Nail Wall
The soil nails are tensioned after the grout sets and the top (stickup) of the soil nails is outfitted
with an anchor place that holds the shotcrete in place. Soil nail walls are installed using top-down
construction. Soil nail walls are typically used for temporary conditions but could be used as
permanent walls. The length of the soil nails is typically about 0.7 times the height of the wall but
could range up to 1 time the height of the wall. Since the soil nails cannot be removed at the end
of construction, soil nails require a permanent construction easement. Soil nail walls are typically
designed by a registered professional engineer engaged by the contractor.
10. Selection of Retaining Wall Type
In our opinion, all the wall types listed above are feasible at the site. However, we believe that
sheet pile walls, if feasible, and soldier pile/micropile and lagging walls used as permanent walls
are a suitable option for the site.
The selection of the type of wall should be based on a cost benefit analysis that takes into account
access to the site, cost of construction, the subsurface condition at the site, proximity to the railroad
tracks, and whether the selected type of wall can be constructed without the need for an SOE
system.
11. Global Stability Analyses
After the alignment of the proposed shared use path and the final grading are established, LGCI
will review the grading plans and perform slope stability analyses where needed. Because the top
Phase I Geotechnical Services

of the slope supports an existing railroad, the minimum target factor of safety for global stability
should be 1.5, i.e., based on a resistance factor of 0.65.
12. Limitation
The recommendations in this report are based in part on the data obtained from discussions with
VHB and mostly desktop review of the conceptual plans provided to LGCI by VHB. No
subsurface explorations were performed by LGCI as part of this preliminary study.
Our preliminary study and recommendations are based on project information provided to us at
the time of this letter report. If changes to the type, size, and location of the proposed structures
or to the site grading are made, the recommendations contained in this letter report shall not be
considered valid unless the changes are reviewed, and the conclusions and recommendations
modified in writing by LGCI.
It is not part of our scope to perform a more detailed site history; therefore, we have not explored
or researched the locations of buried utilities or other structures in the area of the proposed
construction. Our scope did not include environmental services or services related to moisture,
mold, or other biological contaminates in or around the site.
Our letter report has been prepared in accordance with generally accepted engineering practices
and in accordance with the terms and conditions set forth in our agreement. No other warranty,
expressed or implied, is made. This report has been prepared for the exclusive use of Vanasse
Hangen Brustlin, Inc. for the specific application to the CT River Greenway in Northampton,
Massachusetts as conceived at this time.
