FEHR PEERS <br /> 40 <br /> Appendix <br /> Date: October 28, 2020 <br /> To: Glenn Gebhardt and Mark Meissner, City of Lathrop, CA <br /> From: Albee Wei and Fred Choa, Fehr & Peers <br /> Subject: City of Lathrop Travel Demand Forecasting Model and Vehicle Miles Traveled <br /> Technical Memorandum <br /> RS20-3880 <br /> This memorandum documents the methodology for determining Vehicle-Miles Traveled (VMT) from <br /> the City of Lathrop Travel Demand Forecasting Model (Travel Demand Model)and presents a glossary <br /> of VMT-related terminologies used in the River Islands Phase 2 Project Subsequent Environmental <br /> Impact Report (SEIR). <br /> The Travel Demand Model was developed as part of the City of Lathrop's Senate Bill (SB) 743 <br /> implementation and will also be used for the City's General Plan 2040 Update. SB 743 eliminates the <br /> use of automobile delay and Level of Service (LOS) as a potential significant impact under the <br /> California Environmental Quality Act (CEQA), and instead requires all transportation impact analysis <br /> to use VMT for the CEQA environmental review process and the determination of CEQA <br /> transportation impacts.On September 14, 2020,the City of Lathrop adopted Resolution No.20-4787, <br /> which adopted thresholds of significance and screening criteria for the purpose of analyzing <br /> transportation impacts using VMT within the City of Lathrop. Resolution No. 20-4787 also identifies <br /> that previous thresholds regarding LOS shall continue for the purpose of reviewing non-CEQA related <br /> impacts for discretionary planning approvals in accordance with the general plan. <br /> The shift from automobile delay to VMT changes the focus of transportation impact analysis in CEQA <br /> from measuring impacts to drivers, to measuring the impact of driving. The Travel Demand Model <br /> was developed by Fehr & Peers to estimate VMT with consideration of several factors that affect <br /> frequency and distance of vehicle travel, including availability and locations of complimentary land <br /> use, transportation network, distances traveled to and from areas external to the model area, and <br /> availability of high-capacity commuter rail /transit services. <br /> 1001 K Street 1 3rd Floor I Sacramento, CA 95814 1 (916) 262-7392 <br /> www.fehrandpeers.com <br />
