Arico, PE Arico Associates 1407 Route 9 Building 2, Suite 6 Clifton Park, New York 12065 RE: Bemis Point Residential Subdivision City of Saratoga Springs, New York Dear Mr. Arico, Lansing Engineering (LE) has prepared this traffic evaluation to assess the potential traffic impacts for the proposed Bemis Point Residential Subdivision in the City of Saratoga Springs, New York. A copy of the Overall Layout and Site Plan, prepared by your office, dated January 2022, last revised March 10, 2025 is attached. Existing Conditions and Proposed Development The project site, located on the south side of NY Route 29 and at the south end of Lexington Road, is currently undeveloped as shown in the below aerial image, but was previously approved for 39 single family homes. The proposed project consists of the construction of 14 single-family homes, with 13 homes located along an extension of Lexington Road and one home located at the west end of Bemis Heights Road. pg. 2 Access to and from the neighborhood is provided via NY Route 29. The newly constructed homes will be accessed via an extension of Lexington Road with the single home on Bemis Heights Road accessed via Concord Drive and/or Bemis Heights Road and Lexington Road. Site Generated Trips Site generated trips for developments are estimated using the Institute of Transportation Engineers’ (ITE) Trip Generation Manual, 11th Edition1, which is the industry standard for estimating trips for different land uses. Trips for the proposed development were estimated using ITE land use code (LUC) 210 – Single-Family Detached Housing for the weekday AM and PM peak hours. The existing neighborhood consists of 68 single family homes. Trip generation for the existing 68 single family homes was estimated for the weekday AM and PM peak hours to determine the future neighborhood peak hour trip generation with the addition of the proposed 14 homes. The peak hour trip generation for the weekday AM and PM peak hours is summarized in Table 1. Table 1 Trip Generation Summary Land Use AM Peak Hour PM Peak Hour Enter Exit Total Enter Exit Total Current Proposal 14 Single Family Homes 3 9 12 10 6 16 Current Neighborhood 68 Single Family Homes 13 39 52 44 25 69 Future Neighborhood Trips 16 48 64 54 31 85 The table shows that the proposed project is expected to generate 12 vehicle trips (3 entering and 9 exiting) during the AM peak hour and 16 vehicle trips (10 entering and 6 exiting) during the PM peak hour. The magnitude of site generated trips results in significantly less than the New York State Department of Transportation (NYSDOT) and ITE trip thresholds of the generation of 100 vehicle trips on a single intersection approach for determining the need for detailed off-site intersection analysis. These agency thresholds were developed as a tool to identify locations where the magnitude of traffic generated has the potential to impact operations at off-site intersections and to screen out locations that do not meet the threshold and therefore, are unlikely to require mitigation indicating that the site will be adequately serviced by the existing roadway network. A review of the overall neighborhood trips after development of the additional 14 homes indicates the 82 single family homes are expected to generate 64 vehicle trips (16 entering and 48 existing) during the AM peak hour and 85 vehicle trips (54 entering and 31 exiting) during the PM peak hour. The magnitude of traffic generated by the neighborhood will remain below the NYSDOT and ITE trip thresholds of the generation of 100 vehicle trips on a single intersection approach indicating that the neighborhood will continue to be served by the existing roadway network. To further confirm the adequacy of the current neighborhood access to and from NY Route 29, LE reviewed peak hour traffic signal warrant criteria found in the Manual on Uniform Traffic Control 1 Trip Generation Manual, 11th Edition, Institute of Transportation Engineers, Washington D.C., September 2021 pg. 3 Devices for Streets and Highways (MUTCD), 11th Edition2. Per the MUTCD, the minor street approach traffic would need to equal or exceed 100 vehicles per hour with the major street traffic volume equal or exceeding 1,500 vehicles per hour before the criteria is satisfied. As shown in Table 1, the volume exiting Lexington Road is 48 and 31 vehicles during the AM and PM peak hours, respectively. Traffic volume data collected by NYSDOT on NY Route 29 just east of Lexington Road in 2023 illustrates two-way traffic volumes of approximately 830 during the AM peak hour and 1,125 during the PM peak hour. Both the mainline and minor street approach volumes are less than the minimum peak hour traffic signal warrant criteria, indicating that the current stop control remains the appropriate traffic control for this intersection. Conclusions Lansing Engineering has prepared this evaluation summarizing the traffic related to the proposed development of the Bemis Point Residential Subdivision in the City of Saratoga Springs, New York. The following is noted regarding the traffic evaluation: • The site is expected to generate 12 vehicle trips during the AM peak hour (3 entering and 9 exiting) and 16 vehicle trips during the PM peak hour (10 entering and 6 exiting). • The future neighborhood with 82 single family homes will generate 64 vehicle trips during the AM peak hour (16 entering and 48 exiting) and 85 vehicle trips during the PM peak hour (54 entering and 31 exiting). • Based on a review of the magnitude of site traffic, overall neighborhood traffic, and peak hour traffic signal warrant criteria found in the MUTCD, the existing unsignalized access to NY Route 29 via Lexington Road remains the appropriate traffic control from the neighborhood. • No traffic related mitigation is recommended. Please call with questions regarding the above evaluation. Sincerely, LANSING ENGINEERING, PC Wendy C. Holsberger, PE, PTOE, RSP1 Alanna M.
