North Andover — Proposed IEaglewood Retail Development
Preliminary Traffic Findings
Vanasse Hangen Brustlin, Inc. (VHB) has assessed the potential traffic impacts of a new retail
development proposed to be located on Route 114 across from the Lawrence Eagle Tribune site
in North Andover, Massachusetts. The proposed project consists of the construction of a retail
"lifestyle center"consisting of two main components: an approximately 20,400 square foot retail
building at the southerly portion of the site, and 59,525 square feet (sf) of retail building space at
the northerly end of the site. The freestanding building at the southerly end will be occupied by a
single retail tenant, and the northerly retail building will include eight or nine tenant spaces
ranging in size from 4,250 sf to 14,875 sf.While specific tenants have not yet been finalized,
there will be a single quality sit-down restaurant (approximately 140 seats)with the remainder of
the tenants being mostly"soft-goods"oriented; i.e., clothing stores, apparel, etc. In total, there
will be approximately 79,925 square feet of building space within the overall 6.2±acre site.
Northmark Bank is located within an approximately 1.15 acre parcel that falls between the
southerly and northerly portions of the site. The Eaglewood project proponent is committed to
working with this abutting property owner through the local and state process to ensure that safe
and efficient access to the bank is provided. With the proposed roadway improvements,turning
movements to and from that site should occur with considerably more ease than under existing
conditions.
Primary access to the site is proposed via a signalized driveway located opposite the existing
main driveway to the Lawrence Eagle Tribune. Customers using this driveway will be able to
access both the southerly and northerly portions of the site. The design of this signalized
intersection will be under MassHEghway jurisdiction, as Route 114 is a state highway adjacent to
the site. Likewise, given the state jurisdication the project will undergo a thorough review under
the Massachusetts Environmental Policy Act(ME;PA). This review will consist of a detailed
evaluation of the project's potential impact to traffic,the environment and other areas. The public
will also have input to this process, in addition to that which will occur as part of the local
permitting. The Route 114 design at the site entrance is expected to consist of a maximum
cross-section of five lanes: two through-lanes in each direction, with opposing left-turn lanes
provided to both the project site and the Lawrence Eagle Tribune. While this design is still at the
early conceptual level, exclusive entering left-turn signal phases will likely be provided to both
sites. This cross-section, and the sidewalk currently located on the easterly side of the roadway
will all be provided within the existing state highway layout. Finally,following consultation
MassHighway it appears likely that the existing exit driveway from the bank will need to be closed
due to its proximity to the signal. To provide proper access to that site, a full access connector
driveway will be provided to the main site driveway extending from the signal. The Proponent will
work with both the Town and MassHighway throughout the design process to develop a mutually
agreeable access plan, which is also compatible with the needs of nearby residences.
A driveway will also be provided directly to the southerly portion of the site from Route 114, as
motorists on Route 114 may not be immediately aware of the proposed connector roadway
between the two ends of the site, which will extend behind Northmark Bank. To minimize any
conflicts on Route 114, the proposed southerly driveway will be restricted to entering right-turn
movements only. An entering right-turn only driveway Is also proposed to be located at the
northerly end of the site. This driveway is primarily needed to accommodate delivery vehicles,
the majority of which are expected to arrive to the area via Route 1-495. However, this driveway
will also serve the limited portion of entering customer traffic from the south that passes by the
main site driveway, possibly to visit the restaurant at the northerly end of the site. The scope of
the preliminary traffic assessment was based on input from the Town of North Andover. The
findings of the site access assessment are that the proposed traffic signal and geometric
modifications will provide safe and efficient access to the proposed site and abutting sites. The
Proponent is also having ongoing discussions with MassHighway regarding the appropriate
F.1083541docsVcportslrezoning—traffic.doc
treatment of a new signal on Route 114. Based on preliminary meetings, some form of
communication will be established with the nearby signals to the north (Route 114 at Peters
Street, and Route 114 at Route 125/Route 133/Elm Street) and to the south (Route 114 at
Waverly Road). As no such communication currently exists between the two signals immediately
to the north and south of the site, the proposed project will provide an opportunity to address the
lack of coordination between these locations.
Existing Traffic Conditions
The proposed site is located along Route 114, across from the Lawrence Eagle Tribune, in North
Andover. Adjacent to the site, Route 114 is a four-lane roadway under MassHighway jurisdiction.
Although turning lanes are present at the signalized intersections bracketing the site, they are not
currently provided at the Eagle Tribune driveway. VHB has reviewed accident records for several
intersections in the vicinity of the proposed project for a three-year period from 1998 to 2000.
These intersections included Route 114 at Waverly Road, Eagle Tribune Driveway, Peters Street
and Route 125/Route 133, Route 125/Route 133 at Peters Street, and Haverhill Street at High
Street. During the three-year time period, only one accident was reported at the Eagle Tribune
Driveway at Route 114 intersection, Moreover, only one intersection exceeded the MassHighway
crash rate average for the district. This location consisted of the Route 114 at Route 125/Route
133 intersection, which experienced 88 accidents from 1998 through 2000. The merging and
splitting-off of Route 125 from Route 114, however, creates some confusion in the area regarding
intersections nomenclature. Therefore, it is possible that some of the accidents reported at this
location may have in reality occurred at the Route 114 at Andover By-pass (Route 125)
intersection. Review of the reported accidents at this alternate location indicate that is
experienced 22 accidents, a number significantly smaller than the one reported for the Route 114/
Route 125/Route 133 intersection. Consequently, it seems plausible that some of the accidents
reported at the Route 114/Route 125/Route 133 may indeed have happened at the Route 114/
Andover By-pass intersection. Thus, the study area does not appear to present above average
safety concerns given the traffic volume these roadways carry. Regardless, VHB will confer with
the North Andover Police Department to identify special concerns beyond those reflected by the
reported accident records.
Route 114 in the vicinity of the site carries between approximately 30,000 and 38,500 vehicles on
a typical weekday. During the evening peak hour, approximately 2,705 vehicles.travel on Route
114 with the direction of travel slightly heavier in the eastbound direction. On a Saturday, Route
114 carries between approximately 24,000 and 31,500 vehicles throughout the.day and 2,195
during the midday peak hour. On Saturdays, the direction of travel is slightly higher in the
westbound direction. Due to the heavy traffic volumes encountered on Route 114, most of the
intersections In the study area are currently operating near or above capacity.
Future Traffic Conditions
A five-year study horizon, in accordance with MEPA guidelines, was used in this assessment. To
establish baseline traffic conditions in 2008, both normal regional traffic growth, as well as traffic
generated by specific development projects in the area,were considered. The specific site-
generated traffic accounted for in the analysis includes the Den Rock residential development on
Route 114 just north of the Waverly Road intersection. Additional potential projects were
investigated including a potential CVS Pharmacy to be located at the southeast corner of the
Route 114/Peters Street Intersection. However, at the present time these projects are only in the
early conceptual stages. As these projects move forward at varying schedules, VHB will review
their potential impacts on the proposed roadway design.
As previously mentioned, primary access to the site is proposed via a signalized driveway on
Route 114 opposite from the Eagle Tribune driveway. Secondary access will be provided via two
right-in only driveways located on either side of the primary drive.

Trip Generation
To estimate the number of vehicle-trips estimated to be generated by the proposed development,
up to 79,930 square feet of retail uses, VHB used standardized trip generation rates published in
the Institute of Transportation Engineers Trip Generation' report. 1TE land use code 820,
Shopping Center,was determined to be the most appropriate use for this development. Based
on this information, the proposed retail development is expected to generate 540 vehicle trips
(260 entering and 280 exiting) during the weekday evening peak hour, and 755 vehicle trips (390
entering and 365 exiting) during the Saturday midday peak hour. Given the nature of retail uses,
the project is expected to generate minimal volume of traffic during the morning peak commuter
period. During the weekday evening and Saturday midday peak hours only 410 and 565 vehicle
trips, respectively are expected to represent new traffic to the area. The remaining customers are
expected to be in the form of pass-by traffic, which refers to motorists already traveling past the
site on Route 114. These customers will now turn into the site to shop before continuing onto
their original destination. As this traffic is already on Route 114,these customers will not
represent an increase in traffic in the area. While ITE indicates that a retail facility of this size
could be expected to generate approximately 35 percent of its peak hour traffic in the form of
pass-by trips, a 25 percent pass-by rate was used for this study in keeping with state standards.
Clearly, the proposed development will generate more traffic than that which could occur with the
development of single family homes, or the small commercial buildings already allowed by right
within the R-4 and B-4 zones. However, the proposed development will provide the opportunity
for long-standing traffic concerns along Route 114 adjacent to the site to be addressed. Likewise,
the proposed site plan provides controlled, efficient access with the primary driveway being
signalized. While the smaller by-right developments would generate less traffic,they would likely
involve multiple curb cuts, which could create additional traffic concerns.
Trip Distribution
The directional distribution of the traffic approaching and departing the site is a function of
population densities, the location of employment, competing shopping opportunities, existing
travel patterns, and the efficiency of the existing roadway system. The trip distribution of the new
site-generated traffic was developed in consideration of these factors and through the use of a
population based gravity model. The resulting trip distribution pattern indicates that
approximately 37 percent of the site-generated trips are expected to use Route 114, 22 percent
from/to west and 15 percent from/to east. Waverly Road carries approximately 19 percent of the
site traffic, 11 percent from/to north and 8 percent from/to south. Approximately 28 percent of the
traffic is estimated to travel on Route 133, 18 percent to/from north and 10 percent to/from south.
The remaining 16 percent is estimated to use Andover Street (13 percent to/from south) and the
Andover By-pass (3 percent to/from south).
Proposed Roadway Improvements
The primary access to the site will require modifications to adequately and safely accommodate
the forecast traffic volumes. Signal warrants were conducted at the Route 114 at Eagle Tribune
Drive/Primary site drive, which indicated that the 8-hour, 4-hour and peak hour warrants were met
for this location. Consequently, a traffic signal will be installed by the proponent at the primary
site drive. Further, Route 114 will be widened to provide a 5-lane cross section, including two
through lanes in each direction and exclusive eastbound and westbound left-turn lanes. Most of
the widening will be accommodated within the existing MassHighway Right-of-Way(ROW). To
accommodate sidewalks on the property side of Route 114, some widening outside of the existing
ROW will be required. These widenings, however, will occur on the site's side of Route 114.
Finally, due to the close proximity of the proposed signal to the Route 114 at Peters Street signal
and the Route 114 at Waverly Road signal, coordination among the signals will be provided. The
system will include in total four traffic signals along Route 114: Route 125/Route 133, Peters

Street, proposed signal and Waverly Road. This system will ensure that the flow of traffic along
Route 114 continues to operate appropriately.
Conclusion
The proposed site plan will provide safe and efficient access to the proposed retail site from the
surrounding roadway network. A new traffic signal proposed on Route 114 at the site's primary
drive/Eagle Tribune drive will help customers to safely enter and exit the site. The traffic signal
will be coordinated with nearby signals along Route 114 to ensure appropriate traffic flow. The
proposed site driveway will require an Access Permit from MassHighway. Given the size of the
.proposed development, and the geed for a MassHighway permit, the project will also be subject
to review under the Massachusetts Environmental Policy Act (MEPA). The proponent is
committed to continuing to work with the Town of North Andover and MassHighway to address
any traffic concerns during the ongoing local approvals, and during the subsequent MEPA review
process.
