Traffic Operations Review - Proposed GFM Property Subdivision - Lawton Road - Clay ================================================================================ 1396 White Bridge Road Chittenango, NY 13037 Tel: (315) 391-5110 March 20, 2026 Cornerstone Homes CNY, LLC 2501 Mystical Way Camillus, NY 13031 Attn: Mr. Michael Bragman, Jr. Re: Traffic Operations Review – Proposed GFM Property Subdivision Lawton Road – Town of Clay, NY Dear Mr. Bragman: I have completed my review of the traffic operations associated with the proposed GFM Property Subdivision on Lawton Road in Town of Clay, NY. This letter summarizes the work completed in this review as well as my findings. Project Understanding The project site is located on the west side of Lawton Road, to the south of Dongara Lane in the Town of Clay, NY. The proposed subdivision includes 55 single family homes on a roughly 20 acre piece of property. Access to the development will be provided via an extension of Harriet Fisher Drive through the subdivision, connecting to Lawton Road approximately 160 feet to the south of Dongara Lane. The overall site plan developed by Ianuzi & Romans Land Surveying has been attached. Trip Generation Estimate The proposed GFM Property Subdivision includes 55 single family homes. Trips generated by the proposed development were reviewed using the ITE Trip Generation, 12th Edition, which is the industry accepted standard for estimating traffic generated by new developments. Land Use 210 – Single-Family Detached Housing was used for the estimate. The following table summarizes the trip generation estimate for the proposed GFM Property Subdivision in Town of Clay, NY. Trip Generation Estimate – Proposed GFM Property Subdivision Morning Evening Saturday Peak Hour Peak Hour Peak Hour Entering Exiting Entering Exiting Entering Exiting Single Family Homes 10 28 32 19 29 26 55 Units The detailed trip generation calculations have been attached. Mr. Bragman March 20, 2026 Page 2 of 4 Re: Traffic Operations Review – Proposed GFM Property Subdivision Lawton Road – Town of Clay, NY Many people expect that residential land uses will generate an average of 2 trips per unit during peak hours. The trip generation rates for residential land uses are generally less than 1 trip per unit for a number of reasons. The primary reason is that people work different times, some may leave for work at 6:30 in the morning while others may leave at 7:30 or 8:30. Subsequently, the arrival patterns home in the evening will also be staggered over multiple hours. Some people work evenings while others may stay at home or work from home. The rates contained in the ITE Trip Generation have been verified and provide an accurate representation of what may be expected for this development during the peak hours of the adjacent streets. Overall, the proposed GFM Property Subdivision is a minimal traffic generator that will generate approximately 20-30 vehicles per hour entering and exiting the area during the peak hours. This equates to approximately 1 additional vehicle entering and exiting the area every 2-3 minutes during the peak periods of operation on the adjacent streets. Existing Operations Lawton Road is classified as an urban local roadway running from NYS Route 31 to the north to Caughdenoy Road to the south, and has one lane in each direction passing the site. The posted speed limit on Lawton Road is 30 mph. The intersections of Lawton Road with both NYS Route 31 and Caughdenoy Road are controlled by fully actuated traffic signals under the jurisdiction of NYSDOT at NYS Route 31 and OCDOT at Caughdenoy Road. Based on a traffic count collected by GTS Consulting on Lawton Road at Bingley Lane on November 7th, 2024, there are approximately 88 vehicles northbound/65 vehicles southbound to the north of Dongara Lane during the weekday morning peak hour (7-8am) and 96 vehicles northbound/131 vehicles southbound to the north of Dongara Lane during the weekday evening peak hour (4:15- 5:15pm). The 2024 traffic volume count data has been attached. The following table provides a summary of the recommended sight distances along Lawton Road from the AASHTO A Policy on Design of Highways and Streets as well as the available sight distances at the proposed Harriet Fisher Drive extension connection based on field measurements. The speed limit in the area is 30 mph on Lawton Road, therefore 35 mph was used for the sight distance review. Mr. Bragman March 20, 2026 Page 3 of 4 Re: Traffic Operations Review – Proposed GFM Property Subdivision Lawton Road – Town of Clay, NY Sight Distance Summary AASHTO Operating Recommended Available Location Speed Direction Sight Distance Sight Distance Proposed Access @ Looking Left 390 feet 1,400+ feet 35 mph Lawton Road – Turning Left Looking Right 390 feet 800+ feet Proposed Access @ 35 mph Looking Left 335 feet 1,400+ feet Lawton Road – Turning Right There are more than adequate sight distances available in both directions on Lawton Road from the proposed Hariet Fisher Drive access connection. There are no concerns with sight distances and safety for ingress and egress from the proposed side road. Potential Impacts on Adjacent Streets The increase in new trips of approximately 1 additional vehicle entering/exiting the area every 2-3 minutes will generally not even be noticeable to existing motorists in the area. With signalized access to NYS Route 31 to the north and Caughdenoy Road to the south, the minimal increase in traffic is not anticipated to have any notable impact on traffic capacity operations. With 88-96 vehicles in the northbound direction on Lawton Road and 65-131 vehicles in the southbound direction on Lawton Road passing the site during the peak hours, assuming uniform traffic arrival, the average gap in traffic between each vehicle is over 40 seconds in both directions during the weekday morning peak hour and over 25 seconds in both directions during the weekday evening peak hour. A vehicle only requires a 6-9 second gap in the traffic to safely turn on or off a side road on a two lane roadway. There are no concerns with available gaps in traffic on Lawton Road to accommodate traffic turning in or out of the development. Conclusions The additional traffic generated by the proposed GFM Property Subdivision is minor with approximately 1 vehicle entering and exiting the overall area every 2-3 minutes during the peak hours on the adjacent streets. There are excellent sight lines looking in both directions along Lawton Road from proposed access to provide safe access. Existing traffic volumes on Lawton Road are relatively low with plenty of gaps in traffic to accommodate turning movements at the access. There are no concerns with traffic operations in the area and no mitigation measures are recommended.
