Trip generation data was collected at the existing Stewart's Shop convenience market and the East Side Wine and Spirits liquor store located on Maple Dell during the AM and PM peak hours on February 10 and 11, 2021. In addition, trip generation data was also collected for the existing Mobil Gas Station and the Clean02 car wash at the same time. A summary of the existing trip generation for the land uses on Maple Dell and Marion Avenue is included on Table 2 .

The trip generation of the new Stewart's Shop was estimated using land use code ( �UC) 945 for a Convenience Store/Gas Station . The existing 2,000 SF liquor store does not generate traffic during the AM peak hour; however, it generates approximately 21 trips per 1,000 SF during the PM peak hour. The trip generation estimate for the new 3, 180 SF commercial space located at 33 Marion Avenue is based on this observed trip rate since it is assumed that the liquor store will relocate into this larger space. It is assumed that the trips associated with the existing car wash on Marion Avenue will stay the same after redevelopment of the site since the land use will not change. It is noted that the construction of the proposed Stewart's Shop will replace/repurpose the existing Mobile Gas Station and car wash into a new and improved store; therefore, these existing trips were removed from the total trip generation of the site since they currently exist on Marion Avenue. It can be expected that some trips to the gas station/convenience store originate from traffic that is already passing the site on Marion Avenue. Pass-by trips are vehicles that will stop at the site before continuing on to their primary destination . For example, a driver traveling northbound on Marion Avenue leaving work may stop at the convenience store and then continue northbound towards home. This type of trip is considered a pass-by trip. Based on a review of data published by ITE, a pass-by trip percentage of 60% to 65% was applied to trips generated by the gas station/convenience store. It is anticipated that trips generated by the � �r�i�h��r� � - � ��.��;��-M� Mr. Chuck Marshall Updated February 10, 2022 Page 3 of 4 liquor store could also be reduced by a pass-by credit; however, ITE does not provide pass-by credits for this type of land use. In order to provide a conservative assessment, a pass-by credit was not applied to the liquor store commercial space. A summary of the trip generation at 33 Marion Avenue is shown in Table 3 .

It is noted that the site will generate two fewer AM peak hour trips and 40 fewer PM peak hour trips when compared to the trip generation assessment conducted for the previous site plan that included a larger commercial space and four residential townhouse units.

It is noted that the site will generate two fewer AM peak hour trips and 40 fewer PM peak hour trips when compared to the trip generation assessment conducted for the previous site plan that included a larger commercial space and four residential townhouse units.
