TECHNICAL MEMORANDUM TO: Charlie Severs, PE, Project Manager SCJ Alliance FROM: George Smith, Senior Transportation Planner DATE: March 26, 2019 PROJECT #: 3257.01 Phase 01 SUBJECT: Centralia Dollar General - Trip Generation Estimate INTRODUCTION Dollar General proposes construction of a Dollar General neighborhood store in Centralia, Washington. The project will consist of construction of a new 9,100-sf building with 30 parking stalls. The purpose of this letter is to provide an estimate of the vehicular traffic generation.

The development will be located on currently vacant property south of W Reynolds Avenue across the street from Centralia Self Storage. The development will provide one driveway on W Reynolds Avenue. The proposed project will provide 30 parking stalls on-site. The preliminary site plan is attached. SITE-GENERATED TRAFFIC VOLUMES Vehicle trip generation was calculated using the trip generation rates contained in the current edition of the Trip Generation report by the Institute of Transportation Engineers (ITE). The Variety Store category (land-use code #814) was determined to be the most applicable to this project. The following is a quote from the ITE description of the Variety Store Land Use: A variety store is a retail store that sells a broad range of inexpensive items often at a single price. These stores are typically referred to as “dollar stores.” The average building size of stores included in the ITE trip generation study is 9,000-sf which aligns with the proposed Centralia project. It is anticipated that this project will attract some traffic from people already driving on the area roadways. These trips are not new trips added to the local roadways (primary trips) but represent “pass-by” trips according to the following definition: Pass-by Trips are trips made as an intermediate stop from an origin to a primary destination by vehicles passing directly by the project driveway. The new-to-network trip total reflects an estimated 34% occurrence of “pass-by” vehicles. The trip generation calculations for this analysis are shown in Table 1. March 26, 2019 Page 3 of 3 Table 1.
