Page 1 Date: July 23, 2024 To: Colin Cortes, AICP, City of Woodburn Jenna Bogert, PE, DKS Associates From: Joe Bessman, PE Project Reference No.: 1584 Project Name: Woodburn US Market The purpose of this memorandum is to provide a formal response to review comments received from the City of Woodburn (through their on-call review consultant) dated July 19, 2024, which identify Jenna Bogert as the engineer of record. Comment Traffic Counts Dates. The City’s consultant transportation reviewers commented that traffic counts in the original study were from 2019, and that in February 2024 the reviewer requested that a new study be provided, which was provided to DKS in July 2024 (report is dated April 4, 2023). Response: None of the traffic counts within the current or prior application were from 2019. To ensure that the consultant reviewer has access to the correct files and that those files are included in the record the relevant materials are provided below for the US Market application: • June 23, 2023 Transportation Impact Analysis. This report was provided to the City directly, but it is my understanding that without a complete land use application the report was not uploaded to the file. Key revisions within this report include modification of the OR 214 access to right-in only (removing the right-turn out), as well as minor modifications to the site plan. This report was prepared using morning and evening traffic counts that were collected on April 4, 2023. • August 13, 2021 Transportation Impact Analysis. This report was part of the prior submittal that was not approved by the City of Woodburn due to concerns with compatibility, along with other expressed reservations related to traffic safety (specifically due to the right-turn out onto OR 214 and potential weaving). This report utilized traffic counts that were collected on June 30, 2021. The revised 2023 report includes a comparison to these counts. • The TIA for “Project Basie” (Amazon) included traffic counts from May 25, 2021. These were also reviewed to ensure that the traffic patterns within the revised TIA were consistent with these historical traffic counts. There are no traffic counts collected in 2019 within the subject report (or the prior application). References to 2019 on page 11 of the TIA refer to the preparation of seasonal adjustment factors from ODOT’s lagging publication of data, noting the impacts that COVID had on nearby Automated Traffic Recorder Stations. In comparison of the 2021 and 2023 counts (see Page 10 of the June TIA) we note that the weekday evening peak hour volumes changed very little within this two-year period. Accordingly, traffic counts and data within this study are based on 2023 data and validated with the historical counts from 2021. ---PAGE BREAK--- Woodburn US Market Page 2 Comment Pass-by Rates. It was questioned where the 76% and 75% pass-by rates cited in the June 2023 TIA were derived from, as data within ITE’s Trip Generation Handbook, 3rd Edition cites lower pass- by trip rates. Response: The ITE Trip Generation Handbook, 3rd Edition (which was a companion manual to ITE’s Trip Generation, 10th Edition) is obsolete. This manual was updated with more current pass-by data specific to convenience markets with fuel centers as part of the posted February 6, 2018 errata. This supplement states that the pass-by rates within the Trip Generation Handbook should be removed and replaced with this updated information (see Figure Figure 1. ITE Posting on the removal and replacement of pass-by trip rates related to fuel centers. Source: Trip Generation Handbook Errata 2-6-18. Following this publication, the release of ITE’s Trip Generation Manual, 11th Edition provided a new dataset of pass-by information within its Appendices that includes and further revises the supplemental information released in Errata 2-6-18. The release of the Trip Generation Manual, 11th Edition (the current Trip Generation manual) combined many of the separate fuel center and convenience store land use classifications (ITE 853: Convenience Market with Gasoline Pumps, ITE 945: Gasoline/Service Station with Convenience Market, and ITE 960: Super Convenience Market/Gas Station) into a single land use category with subcategories. The revised pass-by data was prepared to correlate to this new combined classification (ITE 945: Convenience Store/Gas Station), aggregating data from the prior subcategories, while maintaining a distinction between sites based on the general number of Vehicle Fueling Positions (VFPs), which are defined below: ---PAGE BREAK--- Woodburn US Market Page 3 Vehicle Fueling Position—is defined by the number of vehicles that can be fueled simultaneously at a service station. For example, if a service station has two fuel dispensing pumps with hoses on each side of each pump, where only one vehicle can be fueled at a time on each side, the number of vehicle fueling positions is four. (Source: ITE Trip Generation Manual 11th Edition, Chapter 4: Definition of Terms) This manual cites the following pass-by rates for ITE 945: Convenience Store/Gas Station): • Sites with 2 to 8 vehicle fueling positions: 60% AM, 56% PM • Sites with 9 to 20 vehicle fueling positions: 76% AM, 75% PM As the proposed fuel center contains 12 vehicle fueling positions, the cited rates applied within the traffic study match those in the current edition of the ITE Trip Generation Manual. The specific pass-by rate tables from the appendices are included as an attachment.
