Copart USA Traffic Impact Study Elk River, MN 1/14/2020 Regarding the intersection of 161s' Avenue NW & Jarvis Street NW, the peak period for left turns from northbound Jarvis to westbound 161s' Street would be during the a.m. peak hour, when employees are coming to work. The volume northbound turning left is projected to be 45 vehicles per hour with 23 vehicles continuing northbound. The opposing southbound movement on Jarvis is projected to be 16 vehicles per hour. Typically, when a left turn volume exceeds 100 vehicles per hour, a left turn lane is considered. In this case, there would be adequate gaps in the southbound traffic stream (one vehicle averaging every 3 minutes 45 seconds) to preclude the need for a left turn lane. In addition, the northbound through traffic volume would not be unduly delayed by northbound left turning vehicles. Therefore, in this case, no left turn lane is recommended at this time. F. FINDINGS, CONCLUSIONS AND RECOMMENDATIONS • The proposed Copart development will generate traffic in this area of Elk River, but the nature of this online auto auction business will reduce the types of trips this development would generate when compared to the typical used or new auto dealership. Vehicles are brought to the storage lot and added to the inventory. Prospective buyers view and purchase vehicles online. Most vehicles are then picked up and delivered from the Copart lot by vehicle delivery trucks. Typically, the traffic generated by the Copart site is from employees and the delivery trucks themselves. Minor customer traffic is generated, but not on the level of a standard used car lot. • Westwood counted the intersection of TH 10 & Jarvis, and seasonally adjusted the counts to reflect an annualized average volume. Westwood used these results from these counts in our analysis. • As part of this analysis, Westwood reviewed the City's Comprehensive Plan. While currently classified as a local street, Jarvis Street is proposed to be jurisdictionally transferred from City to County road from TH 10 to 165th Street, then a new segment of county roadway is proposed northwesterly to connect with Fillmore Street and then continue to 181st Avenue (County Road 18). Jarvis Street and its connection to Fillmore Street are proposed as minor arterial roadways sometime in the future. Westwood complete a signal justification evaluation for the intersection of TH 10 & Jarvis/Cleveland. The traffic signal warrant analysis assumed Existing, 2023 No -Build and 2023 Build traffic conditions. The results showed no warrants being met on either Existing or No -Build conditions, but two warrants being conditionally met for the 2023 Build condition. In summary, Westwood recommends continued review of traffic patterns at the 18 Westwood
