The purpose of this work effort is to determine whether additional traffic analysis is necessary for the proposed Project based on the City of Fontana Traffic Engineering Division’s Traffic Impact Analysis (TIA) Guidelines for Vehicle Miles Traveled (VMT) and Level of Service Assessment (October 21, 2020) (City’s Guidelines). This Trip Generation Assessment, along with the West Valley Logistics Center Due Diligence Traffic Assessment (revised September 14, 2021, prepared by Urban Crossroads, Inc., referred to hereafter as the 2021 Due Diligence), have been prepared to satisfy Condition of Approval 11 found in City Council Resolution No. 2019-041. This Condition of Approval requires an analysis of impacts generated by the Project, assuming that the Project is considered to be a Fulfillment Center. PREVIOUS TRIP GENERATION A revised due diligence traffic assessment was prepared in September 2021 (2021 Due Diligence) to determine if there are additional traffic deficiencies and improvement needs, based upon a conservative assumption that all 3,473,690 square feet of the Project is developed with High-Cube Fulfillment Center (Non-Sort) Warehouse use (2021 Project) based on the Institute of Transportation Engineers (ITE) trip generation rates for Land Use Code 155. The due diligence assessment compared the findings with the West Valley Logistics Center Traffic Impact Analysis (July 20, 2018, prepared by Urban Crossroads, Inc., referred to hereafter as the 2018 Traffic Study). The 2018 Traffic Study evaluated impacts for a project consisting of 290,590 square feet of Warehousing use and 3,183,100 square feet of High-Cube Transload and Short-Term Storage Warehouse use (Original Project). Table 1 shows the trip generation evaluated in the 2021 Due Diligence as the 2021 Project trip generation was higher than that of the Original Project evaluated in the 2018 Traffic Study. Table 1 shows the 2021 Project evaluated in the 2021 Due Diligence would generate 1,330 more two-way trips per day, with 219 more AM peak hour trips and 182 more PM peak hour trips. It should be noted that the trip generation evaluated in the 2021 Due Diligence was based on the ITE Trip Generation Manual (10th Edition, 2017).

The trip generation rates shown on Table 2 and used for this analysis are based upon information collected by the Institute of Transportation Engineers (ITE) as provided in their latest 11th Edition Trip Generation Manual (2021) for High-Cube Fulfillment Center (Non-Sort) Warehouse use (ITE Land Use Code 155), which was published in September 2021. The following ITE land use code and vehicle mix were utilized for the 2021 Project: • ITE land use code 155 (High-Cube Fulfillment Center (Non-Sort) Warehouse) has been used to derive site specific trip generation estimates for up to 3,439,197 square feet of the proposed Project. The truck percentage was also obtained from the latest ITE Trip Generation Manual (2021). Trip generation for heavy trucks was further broken down by truck type (or axle type). The total truck percentage is comprised of 3 different truck types: 2-axle, 3-axle, and 4+-axle trucks. For the purposes of this trip evaluation, the percentage of trucks, by axle type, were obtained from the South Coast Air Quality Management District (SCAQMD) Warehouse Truck Trip Study Data Results and Usage (2014) recommended truck mix. The SCAQMD performed surveys of operational facilities and compiled the data to provide guidance on the mix of heavy trucks for these types of high-cube warehousing/distribution facilities. Based on this guidance, the following truck fleet mix was utilized for the purposes of estimating the truck trip generation for the site (without cold storage): 16.7% of the total trucks as 2-axle trucks, 20.7% of the total trucks as 3-axle trucks, and 62.6% of the total trucks as 4+-axle trucks.

Daily Charlie McPhee, Steve Hollis, & Brandon Dickens IDI Logistics November 9, 2021 Page 4 of 5 13764-07 TG Letter REV The resulting trip generation for the 2021 Project is shown on Table 3. As shown on Table 3, the 2021 Project is anticipated to generate 6,228 two-way trips per day, with 516 trips generated during the AM peak hour and 550 trips generated during the PM peak hour. TABLE 3: 2021 PROJECT TRIP GENERATION SUMMARY The City’s Guidelines require that truck intensive uses translate heavy truck trips to passenger car equivalents (PCE). As shown on Table 3, the 2021 Project is anticipated to generate 7,596 two-way PCE trips per day, with 635 PCE AM peak hour trips and 610 PCE PM peak hour trips. NET NEW TRIP GENERATION The trip generation comparison shown on Table 4 shows that the 2021 Project is anticipated to generate a total of 78 fewer two-way PCE trips with 6 fewer PCE AM peak hour trips and 6 fewer PCE PM peak hour trips as compared to the trip generation evaluated in the 2021 Due Diligence for the 2021 Project.

As such, additional level of service (LOS) based traffic analysis beyond that included in the 2021 Due Diligence is not required as the net reduction in trips would result in similar or reduced deficiencies.
