Notice of Intent
Improvements on I-91Interchange 19
at Route 9 and Damon Road
Northampton, MA
INTRODUCTION
The Massachusetts Department of Transportation – Highway Division (MassDOT) is proposing
improvements to the intersection of Route 9 (Bridge Street) and Damon Road in Northampton.
The project area is located just west of the Calvin Coolidge Memorial Bridge spanning the
Connecticut River and includes the intersection of Bridge Street and Damon Road/I-91 northbound
off-ramp and the intersection of Bridge Street and the I-91 southbound on-ramp. The project also
includes the Exit 19 acceleration and deceleration lanes on the I-91 mainline. See Figure 1 Locus
Map.
Figure 1 Locus Map
The project evolved from the “Connecticut River Crossing Transportation Study,” in which the
transportation needs of a regional study area from Holyoke to Sunderland were determined,
including the potential need for an additional bridge over the Connecticut River. One of the long-
term recommendations from that study was to improve the traffic operations at I-91 Interchange
19. A subsequent study was undertaken to refine the concept at the specific project location.

Notice of Intent
Improvements on I-91Interchange 19
at Route 9 and Damon Road
Northampton, MA
WETLAND RESOURCE AREAS
The Connecticut River is the dominant wetland resource area adjacent to the project. Although
there are no proposed direct impacts to the river there will be some impacts to its floodplain.
Pursuant to the Massachusetts Wetlands Protection Act (WPA) (MGL, Chapter 131, Section 40)
and in accordance with WPA Regulations (310 CMR 10.00.), the resource area is defined as
Bordering Land Subject to Flooding (BLSF). Impacts and Mitigation will occur to the BLSF for this
project. Refer to Project Impacts and Avoidance, Minimization and Mitigation Measures sections for
descriptions. There are no proposed impacts to the Connecticut River itself (Land Under Water) or
its banks (Bank) or to any Bordering Vegetated Wetlands (BVW).
RIVERFRONT AREA (310 CMR 10.58)
The proposed improvements for the project cannot be designed and constructed in full compliance
with the performance standards for Riverfront Area. The project meets the performance standards
to the extent practicable.
An alternatives analysis was conducted and no economically equivalent alternative was identified.
The area of impact is 6,854 square feet of milling and overlay of a section of Route 9 and the
reconstruction of a section of sidewalk. The proposed project qualifies as an insignificant impact and
is exempt because the area of impact is entirely within an area that has already been disturbed and
consists of roadway and bridge approaches which include paved surfaces with substantial
undisturbed fill material beneath. The material beneath will not be disturbed during the project.
PURPOSE AND NEED
The purpose of the project is to:
Improve traffic operations at I-91 Interchange 19 by addressing capacity deficiencies at
intersections on Route 9 and Damon Road;
Improve access to and from I-91 at the existing interchange;
Reduce accident levels within the immediate vicinity of the interchange;
Adequately prepare for currently projected growth and related transportation needs within
the effective design life of the facility;
Improve stormwater management and quality; and,
Avoid, minimize and mitigate resource area impacts.
The need for transportation improvements at this location is summarized as follows:
Poor levels of service currently occur at the intersection of Route 9/Damon Road/I-91
northbound off-ramp. The intersection experiences long queues, particularly in the
westbound direction. Emergency pre-emption and the operations at a nearby pedestrian
signal contribute to the delays at this location.
By 2034, traffic operations at the intersection of Route 9/Damon Road/I-91 northbound off-
ramp are expected to deteriorate to an overall LOS “E”. Traffic operations at the adjacent
intersection of Route 9/I-91 southbound on-ramp are expected to deteriorate with the
Route 9 westbound left turn operating at LOS “F” and over capacity.

Motorists wishing to access I-91 to the north or egress I-91 from the north in the vicinity of
the interchange are forced to use increasingly congested arterial streets to get to/from the
next interchange.
The alternative access/egress routes currently used by motorists to access I-91 north
includes two to four intersections with above-average accident rates, depending on specific
travel route. Reduction of traffic volume on this route will reduce the number of accidents.
Traffic growth in the study area will continue to worsen traffic operations, affecting both capacity
and safety. Traffic has grown at a rate of 2% per year in the last seven years, increasing congestion
on arterial streets to get to/from the next interchange. See Figure 2 Project Location Map.

EXISTING CONDITIONS
Roadway Network and Surrounding Land Uses
Brief descriptions of the principal roadways in the study area are provided below:
Interstate 91 (I-91)
I-91 is the primary north-south thoroughfare through western New England beginning in New
Haven, Connecticut at I-95 and terminating at Derby Line, Vermont, at the Canadian border. I-91
links the cities of Springfield, Northampton, and Greenfield. I-91 largely follows the Connecticut
River and runs parallel to Route 5 for most of its length. The highway is a divided, limited access
highway providing two lanes in each direction in the study area and is under state jurisdiction.
The portion of I-91 in the study area includes I-91 between and at Interchanges 18, 19 and 20. Exits
18 and 19 are 1.9 miles apart and Exits 19 and 20 are spaced at one mile apart. Exit 18 is a half-
cloverleaf on I-91 providing full access to/from Route 5, Mount Tom Road. The ramps are located
in the southwest and northwest quadrants and the I-91 northbound ramps are signalized at the
intersection with Mount Tom Road.
Currently, Interchanges 19 and 20 operate as a pair to provide full access to/from I-91. Both
interchanges are half diamond interchanges with access to/from I-91 to the south provided at Exit
19 and access to/from the north provided at Exit 20. At Exit 19, the existing ramps are located in
the southeast and southwest quadrants of the interchange and the ramps are signalized at Route 9.
Exit 20 is a partial interchange serving movements to and from the north on I-91, with ramps at
North King Street, north of Bridge Road. Access to I-91 northbound is provided via a right-hand
exit on North King Street northbound. This ramp cannot be accessed from North King Street
southbound. Similarly, the I-91 southbound off-ramp merges onto North King Street southbound.
Route 9
Route 9 through Northampton is generally a two-lane roadway which widens to four through lanes
in the vicinity of I-91 and Routes 5 and 10, with turn lanes at major intersections. Route 9 runs in
the east-west direction and provides a crossing of the Connecticut River into Hadley. Route 9 is
classified as a principal arterial and falls under state jurisdiction east of Grant Avenue. Proceeding
westerly, Route 9 is under City jurisdiction. Route 9 is a primary access route to the main campus
of the University of Massachusetts, Amherst. The posted speed limit on Route 9 is 30 mph in the
vicinity of I-91 and 25 mph in the downtown commercial area near Market Street and King Street.
At Exit 19, Route 9 is signalized. The intersection of Route 9/I-91 southbound on-ramp is a three-
legged intersection; the left turn and eastbound through movements are controlled by signalization.
The I-91 northbound off-ramp intersects Route 9 opposite of Damon Road forming a four-legged
intersection. Exclusive turn lanes are provided for the Route 9 eastbound left turn and westbound
right turn. The I-91 off-ramp has an exclusive left turn lane, a through lane and a channelized right
turn lane. The Damon Road approach has two exclusive left turn lanes and an exclusive right turn
lane. One signal system controls the movements at the two adjacent intersections.

Route 9 generally serves residential land uses in the vicinity of I-91. As one proceeds westerly on
Route 9, the land use becomes commercial. Between King Street and I-91, there are traffic signals
at the intersections with King Street, Market Street/Hawley Street, a pedestrian signal between old
Ferry Road and Day Avenue, at the I-91 southbound on-ramp and at the I-91 northbound off-
ramp/Damon Street.
Damon Road
Damon Road runs generally parallel to I-91 in a north-south direction from Route 9 near
Interchange 19 and then proceeds westerly crossing under I-91 and terminating at the four-legged
signalized intersection with King Street, North King Street (Routes 5 and 10) and Bridge Road.
Damon Road carries one travel lane in each direction and provides auxiliary turn lanes at its
intersections with Route 9, Industrial Drive and Routes 5 and 10. Damon Road is classified as an
urban minor arterial and is under City jurisdiction.
PROPOSED IMPROVEMENTS
I-91 Northbound Off-Ramp at Damon Road
The intersection of the northbound off-ramp and Damon Road will be reconstructed as a two-lane
roundabout with a bypass lane for vehicles accessing Route 9 westbound from Damon Road. All
approaches to the roundabout will be two lanes as well. The roundabout will include a truck apron
along its inscribed diameter and a landscaped central island.
A shared use path will be provided around the entire roundabout with the exception of on Route 9
westbound where it passes under the I-91 bridges. At this location, a 5.5 foot sidewalk will be
provided.
I-91 Southbound On-Ramp at Route 9
Traffic operations will remain essentially the same as existing conditions with the exception of an
added left turn lane from Route 9 westbound onto the southbound on-ramp (one lane currently
exists, there will be two with the proposed improvements). The southbound on-ramp will be
widened to two lanes to accept the additional left turn lane from Route 9 westbound. The lane will
be dropped on the ramp prior to the merge with I-91.
I-91 Northbound Off-Ramp and Southbound On-Ramp
The deceleration length on the northbound off-ramp and the acceleration lane from southbound on-
ramp will also be increased by widening the ramps.
CONSTRUCTION STAGING
The proposed roadway construction will be completed via staged construction. It is anticipated that
this method for construction will be completed within two construction seasons and will have three

primary stages and a fourth for final paving and landscaping. Throughout construction, access to all
driveways will be maintained. Pedestrian accommodations will also be maintained throughout
construction by use of the existing signalized pedestrian crossings, a police detail or introduction of
temporary sidewalks and crosswalks. The intention is to maintain the current number of lanes on
all roadways throughout construction; however periodic short term lane closures may be required
to perform isolated work items.
Stage 1
During the first stage of construction, traffic will be operating primarily on the existing roadways.
Existing sidewalks will remain open throughout this stage to accommodate pedestrian traffic. The
extension of the northbound off-ramp deceleration will be constructed. At the roundabout, the
eastern half and southeastern quadrant of the roundabout will be constructed where it does not
conflict with the existing northbound off-ramp. The proposed sidewalk on Damon Road
southbound will also be constructed during this stage. Upon completion of the portion of roadway
outside of the existing roadway footprint, the northbound off-ramp traffic will be shifted to the
newly constructed roadway while the existing northbound off-ramp is reconstructed to its
permanent configuration. At the end of Stage 1, the roundabout on the eastern side of Route 9 will
be fully constructed.
Stage 2
For Stage 2, traffic will be shifted into an interim roundabout alignment. The eastern half of the
roundabout (at the northbound off-ramp) will essentially be in its permanent configuration, while the
western half of the roundabout (at Damon Road) will be constructed using a series of traffic shifts
through the roundabout.
Stage 3
Stage 3 will consist of constructing the final connections to Damon Road northbound. Upon
completion of Stage 3, the entire roundabout will be constructed up to the intermediate pavement
course.
Stage 4
The permanent roundabout will be opened to traffic while the surface course of pavement is
constructed and the final pavement markings and landscaping are placed.
PROJECT IMPACTS
There are wetland resources, surface waters, floodplains, rare, threatened or endangered species,
wildlife habitat or significant natural resources within the project limits or within the project area.
There are no Areas of Critical Environmental Concern (ACEC) in Northampton. The Connecticut
River lies to the north and east of the I-91, Route 9 and Damon Road intersections, but will not be
directly impacted by the project. The 100-year floodplain of the Connecticut River is extensive and
includes some of the roadway systems within the project limits.

Impacts to approximately 25,984 square feet of Bordering Land Subject to Flooding (BLSF) will
occur to construct this project. Approximately 10,999 square feet will be impacted adjacent to the I-
91 southbound on-ramp and 14,985 square feet will be impacted adjacent to the I-91 northbound
off-ramp. These impacts will result in approximately 2,565 cubic yards, or 69,255 cubic feet of flood
storage lost due to fill material required to safely reconfigure the ramps. The slopes adjacent to the
ramps will be constructed at 1:1 (H:V), in order to minimize the impacts.
The Connecticut River Greenway State Park is located within the project area and is bordered by
Route 9, Damon Road, and the Connecticut River. The Connecticut River Greenway is actually a
system of state parks that connects open spaces, parks, scenic vistas, and archaeological and historic
sites along the length of the Connecticut River as it passes through the state. There are over 12
miles of permanently protected shoreline, and numerous access points to the river. The
Norwottuck Rail Trail passes through a section of this state park near the project limits. The Elwell
Recreation Area is a component of this state park and includes the paved access ramp and dock
system along the river. The project will not impact the state park.
AVOIDANCE, MINIMIZATION AND MITIGATION MEASURES
A complete, detailed Stormwater Pollution Prevention Plan (SWPPP) will be prepared for the
project by the contractor as required by the NPDES General Permit for Construction, prior to
construction. The erosion and sedimentation control program will be implemented to avoid and
minimize temporary impacts to abutting areas during the construction phase of the project. The
program will incorporate Best Management Practices (BMPs) specified in guidelines developed by
the Massachusetts Department of Environmental Protection (DEP) (DEP, Massachusetts Erosion and
Sediment Control Guidelines for Urban and Suburban Areas: A Guide for Planners, Designers, and Municipal
Officials Original Print: March 1997 Reprint: May 2003) and the U.S. Environmental Protection
Agency (EPA) (EPA, Developing Your Stormwater Pollution Prevention Plan: A Guide for Construction Sites
EPA 833-R-06-004 May 2007).
The proposed project will be constructed in stages to keep the roadways open to traffic at all times.
Standard construction techniques and safety measures will be used during the stages. Standard
sedimentation controls will be installed and maintained during construction to assure temporary
disturbance of the surrounding sediments is minimized and contained within the immediate area.
Upon completion of the project, exposed soils will be seeded to provide stabilization.
In order to replace the impacted BLSF, due to the construction of the proposed slopes adjacent to
the I-91 southbound on-ramp and the I-91 northbound off-ramp, excavation of approximately
54,287 square feet is required. Approximately 14,014 square feet will be excavated to construct the
I-91 southbound on-ramp, and approximately 40,273 square feet will be excavated to construct the
I-91 northbound off-ramp. The excavation will create approximately 2,846 cubic yards of mitigation,
or 76,842 cubic feet of compensatory storage for the BLSF. The impacts and mitigations are detailed
by elevation in Tables 1-3.

PERMITTING STATUS
An Environmental Notification Form (ENF) was prepared in 2006. At that time the preferred
alternative for this project involved more significant changes to the I-91 at Route 9 interchange
including new ramps. It was determined that an ENF was required because the project required the
widening of an existing roadway for one-half or more miles; altered terrain ten or more feet from
the existing roadway for one-half or more miles; resulted in the alteration of one-half or more acres
of wetlands; and would have resulted in the construction of 0.9 miles of new roadway. The current
proposed improvements will not exceed any of these other thresholds; an ENF will not be required.
There are wetland resources and surface waters within the project limits associated with the
Connecticut River. No proposed drainage improvements will involve outlet structures at the
Connecticut River. Therefore, the project will not require permits relative to the Section 401 or
404 of the Federal Clean Water Act.
According to the 2008 Massachusetts Natural Heritage and Endangered Species Program (NHESP)
Map, the project area is located within Priority Habitat of Rare Species and/or Estimated Habitats of
Rare Wildlife. The species known to occur within this area include rare fish, bird, mussel, and
dragonfly species. No impacts are expected to any of these species. There are no Certified Vernal
Pools within or near the project limits. At this phase of the design, the project is expected to be
exempt from the Massachusetts Endangered Species Act (MESA). MassDOT Environmental Section
will continue to coordinate with the Massachusetts NHESP. A letter dated June 19, 2014 was sent to
NHESP along with Exhibits 1-3, which show information about the project area including NHESP
Estimated Habitats of Rare Wildlife. In addition, the MESA Review Checklist for MassDOT –
Highway Division Projects was sent to NHESP. Documentation regarding NHESP is included in
Attachment F.
Additionally, there are no federally-listed or proposed, threatened or endangered species or critical
habitat under the jurisdiction of the U.S. Fish and Wildlife Service known to occur in the project
area.
The project will undergo a review process pursuant to Section 106 and Section 4(f) regulations with
respect to cultural resources. MassDOT Highway Division’s Cultural Resources Unit will consult
with the Massachusetts Historic Commission, Northampton Historical Commission and the FHWA.
ESTIMATED HABITATS OF RARE WILDLIFE (310 CMR 10.59)
The project will include construction activities within close proximity of estimated habitats of rare
wildlife. As required, a copy of the Notice of Intent will be forwarded to the Massachusetts Natural
Heritage and Endangered Species Program for their review.
EROSION AND SEDIMENTATION CONTROLS
Prior to any clearing activities, erosion controls will be installed around all work areas that would
involve soil disturbance. Erosion controls will consist of compost filter tubes set in place by
untreated hardwood stakes. Siltsacks will be installed on all catch basins and drop inlets.

Proper implementation of the erosion and sedimentation control program will:
Minimize exposed soil areas through sequencing and temporary stabilization;
Place structures to manage stormwater runoff and erosion; and,
Establish a permanent vegetative cover or other forms of stabilization as soon as practicable.
The following sections describe the controls that may be used and practices that will be followed
during construction. These controls will be implemented by the contractor, and these practices will
comply with criteria contained in the NPDES General Permit for Discharges from Large and Small
Construction Activities issued by the EPA.
NON-STRUCTURAL PRACTICES
Non-structural practices to be used during construction include temporary stabilization, temporary
seeding, permanent seeding, pavement sweeping and dust control. These practices will be initiated as
soon as practicable in appropriate areas at the site.
TEMPORARY STABILIZATION
Any areas of exposed soil or stockpiles that will remain inactive for more than 14 days will be
covered with a layer of straw mulch applied at a rate of 90 pounds per 1,000 square feet. The straw
mulch may be anchored with a tacking coat applied by a hydroseeder.
TEMPORARY PROTECTION OF EXPOSED SOILS
If conditions allow, a temporary vegetative cover may be established on areas of exposed soils
(including stockpiles) that remain unstabilized for a period of more than 60 days. The exposed soils
will be covered with either straw mulch, or matting for erosion control, depending on the slope of
the exposed soils. Seed the soils only if directed by the Engineer. The seed mix shall include a blend
of rapid-germinating grasses that are indigenous to western Massachusetts.
DUST CONTROL
The erosion and sediment control program includes provisions to minimize the generation of dust
during dry and windy conditions. When necessary, larger areas of exposed soil will be wetted to
prevent wind-borne transport of fine grained sediment. Enough water shall be applied to wet the
upper 0.5 inches of soil. The water will be applied as a fine spray in order to prevent erosion. A
water truck may be brought onto the site as needed to facilitate this practice.

STRUCTURAL PRACTICES
Structural erosion and sedimentation controls to be used on the project area may include barriers,
stabilized construction exits, temporary sediment basins, temporary diversion swales, inlet
protection for catch basins and drop inlets, and dewatering filters.
EROSION CONTROL BARRIERS
Prior to any ground disturbance, a barrier of compost filter tubes with untreated hardwood stakes
will be installed at the downgradient limit of work. As construction progresses, additional barriers
may be installed around the base of stockpiles and other erosion prone areas. The compost filter
tubes will be entrenched into the substrate to prevent underflow.
If sediment has accumulated to a depth which impairs proper functioning of the barrier, it will be
removed by hand or by machinery operating upslope of the barriers. This material will be either
reused at the site or disposed of at a suitable offsite location. Any damaged sections of compost
filter tubes will be repaired or replaced immediately upon discovery.
TEMPORARY SEDIMENT BASINS
Temporary sediment basins may be designed either as excavations or bermed structures (depending
on grading) that will retain runoff for a sufficient period of time to allow suspended soil particles to
settle out prior to discharge. These temporary basins may be located at the low points on the site
(upslope of the perimeter erosion control barrier) and will receive runoff via temporary diversion
swales. Discharge from the basin may be controlled by a perforated riser surrounded by a crushed
stone filter. Points of discharge from sediment basins will be stabilized with rip rap to minimize
erosion.
Once constructed, the basins will be temporarily stabilized by covering them with bonded fiber
matrix. If sediment has accumulated to a depth which impairs proper functioning of the basin, it will
be removed and will be either reused on the site or disposed of at a suitable offsite location. Any
eroded or damaged areas will be repaired immediately upon discovery.
INLET PROTECTION FOR CATCH BASINS AND DROP INLETS
The inlets of active catch basins and drop inlets will be protected from sediment inflow during the
work period by installing, silt sacks. If sediment has collected in the silt sack to a point where it
impairs proper functioning, the sediment should be removed and reused onsite or disposed of at a
suitable offsite location.
DEWATERING FILTERS
If necessary, sediment-laden water that collects in trenches or excavated areas may be pumped into
filter berm basins or filter bags. The basins will consist of filter berms overlain by non-woven
geotextile filter fabric and crushed stone. Discharge water will be pumped into the basin and

allowed to drain through the fabric onto relatively-flat stabilized surfaces. Dewatering filter bags may
be used in place of filter berm basins. The bags will be placed on relatively flat terrain, free of brush
and stumps, to avoid ruptures and punctures. A maximum of one six-inch discharge hose will be
allowed per filter bag. To help prevent punctures, geotextile fabric will be placed beneath the filter
bag when used in wooded locations.
Unattended filter bags will be encircled with compost filter tubes. All dewatering structures will be
placed as far away from wetland resources as possible. Filter bags used during construction will be
bundled and removed for proper disposal.
REGULATORY COMPLIANCE
As demonstrated below, work in the BLSF fully complies with applicable performance standards and
complies with the requirements contained in the Regulations for the Wetlands Protection Act.
LAND SUBJECT TO FLOODING (310 CMR 10.57)
Where a project involves removing, filling, dredging or altering of Land Subject to Flooding (both Bordering
and Isolated Areas) the issuing authority shall presume that such an area is significant to, and only to, the
respective interests specified in 310 CMR 10.57(1)(a) and (b). This presumption is rebuttable and may be
overcome only upon a clear showing that said land does not play a role in the protection of said interests. In
the event that the presumption is deemed to have been overcome, the issuing authority shall make a written
determination to this effect, setting forth its grounds (Form 6).
The proposed improvements have been designed with a concerted effort to minimize
impacts to the Connecticut River floodplain but also need to adhere to modern engineering
standards and work within the framework of the existing roadway and bridge network to
the extent practicable.
The limits of the BLSF within the project area have been defined by the Federal Emergency
Management Agency (FEMA) maps known as Federal Insurance Rate Maps (FIRM)
(Attachment G). In Massachusetts these maps have been transposed onto the MassGIS
system. However, the FEMA National Flood Hazard layer is not available for Hampshire
County, so for Northampton, MassDOT has also given consideration to the Flood Insurance
Study (FIS) for Northampton prepared by FEMA in 1972. This FIS, which references the
FIRM Maps, defined the elevation of the 100-year flood zone to be elevation 125. This map
was superimposed onto the engineering drawings for the proposed project. The
superimposed map, showing the extents of the 100 year flood, as expected, was very similar
to the surveyed contour elevation of 125. For added accuracy, where the extents of the 100
year flood elevation is shown, the extents are adjusted to follow the surveyed contour
elevation of 125. The surveyed 125 contour elevation is used for computing the impacts and
mitigation to the BLSF.
MassDOT has provided compensatory storage volume not previously used for flood storage
incrementally equal to the theoretical volume of flood water at each elevation up to and
including elevation 125. Table 1, Table 2 and Table 3 represent the impacts (Fill) and
