RE: Traffic Assessment, Duplainville Road Warehouse, Duplainville Road, City of Saratoga Springs,
Saratoga County, New York; CM Project No. 122-376
Dear Mr. Munter:
Creighton Manning Engineering, LLP (CM) has conducted a traffic assessment for the proposed Duplainville
Road Warehouse manufacturing facility located in the WJ Grande Industrial Park on Duplainville Road in
the City of Saratoga Springs. This evaluation is based on the proposed “Site & Utility Plan” prepared by
Verity Engineering, D.P.C. dated August 23, 2022 (Attachment A).
1.0 Project Description and Existing Conditions
The project consists of two new manufacturing buildings
totaling 70,480 square-feet (SF) at the western limit of
Duplainville Road (CR 64), adjacent to the Greenfield
Manufacturing facility. Additionally, the project
proposes an extension of the existing freight rail onto the
property of the applicant to accommodate delivery of
product via train. Access to the site will be provided via
one new, full-access driveway located at the western
limit of Duplainville Road. The project location is shown
on Figure 1.
Duplainville Road (CR 64) is a two-lane roadway classified
as an urban local road that provides 11-foot wide travel
lanes in each direction with three to four-foot wide
paved shoulders. Duplainville Road travels in an east-
west direction and provides access through the north
end of the WJ Grande Industrial Park. The posted speed
limit is 30-mph and land uses along the roadway
generally consist of warehousing/manufacturing uses.
2.0 Traffic Forecasts & Assessment
Site Generated Traffic
Trip generation determines the quantity of traffic expected to travel to/from a given site. The Institute of
Transportation Engineers (ITE) Trip Generation, 11th edition, is the industry standard used for estimating
trip generation for proposed land uses based on data collected at similar uses. The trip generation for the
70,480 SF of manufacturing space associated with the proposed project was estimated based on ITE Land
Use Code (LUC) 140 for Manufacturing. Table 1 summarizes the trip generation estimate during the AM
and PM peak hours.

The trip generation summary shown in Table 1 indicates that the new manufacturing space will generate
53 AM peak hour trips and 44 PM peak hour trips based on ITE equations.
Traffic Volume Conditions
Traffic generated by the proposed project was distributed onto the surrounding roadway network based
on probable travel routes. It is expected that approximately 60 percent of the site generated traffic will
travel to and from the east via Geyser Road and approximately 40 percent will travel to and from the west
via Geyser Road. This distribution of traffic results in a maximum increase in traffic of approximately 24 new
vehicle trips during the AM and PM peak hours on any one approach to an intersection located adjacent to
the project site.
The magnitude of the new vehicle trips generated by the site is less than the New York State Department
of Transportation (NYSDOT) and ITE threshold of 100 site generated vehicles on any one intersection
approach for needing off-site intersection analysis. This guidance was developed as a tool to identify
locations where the magnitude of traffic generated has the potential to impact operations at off-site
intersections and screen out locations from requiring detailed analysis that do not reach the 100-vehicle
threshold and are unlikely to require mitigation. The anticipated traffic volumes for the Duplainville Road
Warehouse will be below the 100-vehicle threshold indicating that detailed intersection analysis is not
needed and that the site generated traffic will be accommodated by the existing roadway network.
Site Specific Trip Generation Assessment
Site specific operational data was also provided by the applicant in order to compare the specific
anticipated use to the general ITE rates. It is expected that the site could have potentially 35 employees at
full build-out of the development that generally use a personal car to arrive and depart the site in two or
three shifts. The following summarizes the employee schedule for each scenario:
Three Shift Scenario –
Morning Shift – 15 employees begin at 7:00 a.m., 5 employees depart from night shift
Afternoon Shift – 15 employees begin at 3:00 p.m., 15 employees depart from morning shift
Night Shift – 5 employees begin at 11:00 p.m., 15 employees depart from afternoon shift
Two Shift Scenario –
Morning Shift – 20 employees begin at 7:00 a.m., 15 employees depart from night shift
Night Shift – 15 employees begin at 7:00 p.m., 20 employees depart from morning shift
A review of the two potential shift options indicates that the “Two Shift Scenario” is the worst-case
alternative with regard to trip generation. The hourly inbound and outbound truck delivery for the project
site and employee traffic for the “Two Shift Scenario” is summarized in Table 2 based on the typical delivery
timeframes and work schedules.

A comparison between the site specific trip generation estimates and the general ITE rates indicates that
the site will likely generate less traffic when compared to typical manufacturing facilities.
3.0 Conclusions
The project consists of two new manufacturing buildings totaling 70,480 square-feet (SF) at the western
limit of Duplainville Road, adjacent to the Greenfield Manufacturing facility. Additionally, the project
proposes an extension of the existing freight rail onto the property of the applicant to accommodate
delivery of product via train. Access to the site will be provided via one new, full-access driveway located
at the western limit of Duplainville Road. The Duplainville Road Warehouse facility will generate 53 AM
peak hour trips and 44 PM peak hour trips based on ITE rates. It is expected that there will be a maximum
increase in traffic of approximately 24 new vehicle trips during the AM and PM peak hours on any one
approach to an intersection located adjacent to the project site. The magnitude of the new vehicle trips
generated by the site is less than the threshold for needing off-site intersection analysis. In addition, a
comparison between the site specific trip generation estimates and the general ITE rates indicates that the
site will likely generate less traffic when compared to typical manufacturing facilities. No mitigation is
recommended for the proposed development.
