TS Report II This Page Intentionally Left Blank Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 1 1 INTRODUCTION This report presents the results of the Traffic Study (TS) for the proposed Slover Avenue & Cypress Avenue Warehouse development (“Project”), which is located on the northwest corner of Cypress Avenue and Slover Avenue in the City of Fontana as shown on Exhibit 1-1. The purpose of this TS is to evaluate the potential deficiencies related to traffic, identify circulation system deficiencies that may result from the development of the proposed Project, and to recommend improvements to resolve identified deficiencies in order to achieve acceptable operational conditions at study area intersections and ensure consistency with the City’s General Plan. This TS has been prepared in accordance with the City of Fontana’s Traffic Impact Analysis (TIA) Guidelines for Vehicle Miles Traveled (VMT) and Level of Service Assessment (October 21, 2020) and through consultation with City of Fontana staff during the scoping process. (1) The Project traffic study scoping agreement is provided in Appendix 1.1 of this TS, which has been approved by the City of Fontana. 1.1 SUMMARY OF FINDINGS The Project is to construct the following improvements as design features in conjunction with development of the site: • Project to construct Slover Avenue at its ultimate half-width as a Primary Highway (104-foot right- of-way) from the Project’s western boundary to Cypress Avenue consistent with the City’s standards. • Project to widen the eastern curb on Oleander Avenue to accommodate 28-feet of pavement within a 44-foot right-of-way from the Project’s northern boundary to Slover Avenue consistent with the City’s standards. Additional details and intersection lane geometrics are provided in Section 1.6 Recommendations of this report. There are no off-site improvements recommended as the addition of Project traffic is not anticipated to result in any deficiencies based on the City’s thresholds. As such, the Project Applicant’s shall pay its requisite fees towards future regional roadway improvements consistent with the City’s requirements (see Section 6 Local and Regional Funding Mechanisms). As required by City Guidelines, a project level Vehicle Miles Traveled (VMT) analysis was conducted consistent with the requirements identified for single use warehouse projects. The Project was not found to exceed 15% below the County of San Bernardino’s baseline regional average VMT per Service Population (SP) measures of VMT. The Project’s impact to VMT is therefore presumed to be less than significant. Detail traffic analysis can be found in Section 7 Vehicle Miles Traveled Analysis of this TS. Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 2 EXHIBIT 1-1: LOCATION MAP Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 3 1.2 PROJECT OVERVIEW The proposed Project includes the development of 469,095 square feet of high-cube fulfillment center warehouse use (75% of the total square footage) and 156,365 square feet of high-cube cold storage warehouse use (25% of the total square footage) for a total of 625,460 square feet. The Project is anticipated to be developed within a single phase with an Opening Year of 2023. The preliminary site plan for the proposed Project is shown on Exhibit 1-2. As indicated on Exhibit 1-2, access to the Project site will be provided via Boyle Avenue via three full access driveways and one right-in/right-out access point along Slover Avenue (easterly access on Slover Avenue is to be designated as emergency vehicle access or EVA only). Regional access to the Project site is available from the I-10 Freeway via the Citrus Avenue and Sierra Avenue interchanges. Trips generated by the Project’s proposed land uses have been estimated based on trip generation rates collected by the Institute of Transportation Engineers (ITE) Trip Generation Manual, (11th Edition, 2021) and the High Cube Warehouse Trip Generation Study (WSP, January 2019) were used to estimate the trip generation. (2) (3) The Project is anticipated to generate a total of 1,334 two-way trips per day with 74 AM peak hour trips and 96 PM peak hour trips (actual vehicles). The assumptions and methods used to estimate the Project’s trip generation characteristics are discussed in greater detail in Section 4.1 Project Trip Generation of this report. 1.3 ANALYSIS SCENARIOS For the purposes of this traffic study, potential deficiencies to traffic and circulation have been assessed for each of the following conditions: • Existing (2021) • Opening Year Cumulative (2023) Without Project • Opening Year Cumulative (2023) With Project 1.3.1 EXISTING (2021) CONDITIONS Information for Existing (2021) conditions is disclosed to represent the baseline traffic conditions as they existed at the time this report was prepared. 1.3.2 OPENING YEAR CUMULATIVE (2023) CONDITIONS The Opening Year Cumulative (2023) conditions analysis determines the potential near-term cumulative circulation system deficiencies. To account for background traffic growth, traffic associated with other known cumulative development projects in conjunction with an ambient growth from Existing (2021) conditions of 2.33% is included for Opening Year Cumulative (2023) traffic conditions. The near-term conditions analysis will be utilized to determine if improvements funded through regional transportation fee programs, such as the City’s Development Impact Fee (DIF) program, or other approved funding mechanisms can accommodate the long-range cumulative traffic at the target level of service (LOS) identified by the City of Fontana (lead agency). Other improvements needed beyond the “funded” improvements (such as localized improvements to non-DIF facilities) are identified as such. Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 4 EXHIBIT 1-2: PRELIMINARY SITE PLAN Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 5 1.4 STUDY AREA To ensure that this TS satisfies the City of Fontana’s traffic study requirements, Urban Crossroads, Inc. prepared a Project traffic study scoping package for review by City of Fontana staff prior to the preparation of this report. This agreement provides an outline of the Project study area, trip generation, trip distribution, and analysis methodology. The agreement approved by the City of Fontana is included in Appendix 1.1 of this TS. The 10 study area intersections shown on Exhibit 1-3 and listed in Table 1-1, and 3 roadway segments are identified on Table 1-2 were selected for evaluation in this TS based on consultation with City of Fontana staff. The study area includes intersections where the Project is anticipated to contribute 50 or more peak hour trips per the City of Fontana’s traffic study guidelines. (1) The “50 peak hour trip” criteria represent a minimum number of trips at which a typical intersection would have the potential to be substantively affected by a given development proposal. The 50 peak hour trip criterion is a traffic engineering rule of thumb that is accepted and widely used within San Bernardino County for estimating a potential area of influence (i.e., study area). The intent of a Congestion Management Program (CMP) is to more directly link land use, transportation, and air quality, thereby prompting reasonable growth management programs that will effectively utilize new transportation funds, alleviate traffic congestion and related deficiencies, and improve air quality. Counties within California have developed CMPs with varying methods and strategies to meet the intent of the CMP legislation. Study area intersections that are identified as CMP facilities in the County of San Bernardino per the San Bernardino County Transportation Authority (SBCTA) CMP are indicated on Table 1-1.

Section 2 Methodologies provides information on the methodologies used in the analysis and Section 5 Opening Year Cumulative (2023) Traffic Conditions includes the detailed analysis. A summary of LOS results for all analysis scenarios is presented on Table 1-3. TABLE 1-3: SUMMARY OF LOS 1.5.2 EXISTING CONDITIONS The following study area intersections are currently operating at an unacceptable LOS (i.e., LOS D or worse) during the peak hours under Existing (2021) traffic conditions: • Cypress Avenue & Slover Avenue (#9) – LOS D AM peak hour only • Juniper Avenue & Slover Avenue (#10) – LOS F PM peak hour only 1.5.2 OPENING YEAR CUMULATIVE CONDITIONS The following study area intersections are anticipated to operate at an unacceptable LOS (i.e., LOS D or worse) during the peak hours under Opening Year Cumulative (2023) Without Project traffic conditions: • Citrus Avenue & I-10 EB Ramps (#2) – LOS F AM peak hour only • Citrus Avenue & Slover Avenue (#3) – LOS F AM and PM peak hours • Oleander Avenue & Slover Avenue (#7) – LOS E AM peak hour only #Roadway Segments 1 Slover Av. between Citrus Av. & Oleander Av. 2 Slover Av. between Oleander Av. & Cypress Av. 3 Slover Av. between Cypress Av. & Juniper Av. #Intersection AM PM AM PM AM PM 1 Citrus Av. & I-10 WB Ramps 2 Citrus Av. & I-10 EB Ramps 3 Citrus Av. & Slover Av. 4 Oleander Av. & Driveway 1 N/A N/A N/A N/A 5 Oleander Av. & Boyle Av./Driveway 2 6 Oleander Av. & Driveway 3 N/A N/A N/A N/A 7 Oleander Av. & Slover Av. 8 Driveway 4 & Slover Av.N/A N/A N/A N/A 9 Cypress Av. & Slover Av. 10 Juniper Av. & Slover Av. = A - C = D/E = F Existing 2023 Without Project 2023 With Project Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 8 • Cypress Avenue & Slover Avenue (#9) – LOS D AM peak hour only • Juniper Avenue & Slover Avenue (#10) – LOS E AM peak hour; LOS F PM peak hour No additional intersections are anticipated to operate at an unacceptable LOS (i.e., LOS D or worse) during the peak hours under Opening Year Cumulative (2023) With Project traffic conditions, in additional to the intersections listed above. However, the LOS at the intersection of Oleander Avenue and Slover Avenue is anticipated to worsen from LOS E to LOS F with the addition of Project traffic. 1.6 RECOMMENDATIONS 1.6.1 SITE ADJACENT AND SITE ACCESS RECOMMENDATIONS The following recommendations are based on the minimum improvements needed to accommodate site access and maintain acceptable peak hour operations. The site adjacent recommendations are shown on Exhibit 1-4. Recommendation 1 – Oleander Avenue & Driveway 1 (#4) – The following improvements are necessary to accommodate site access: • Project to maintain the stop control on the westbound approach. • Project to accommodate shared left-right turn lane on westbound approach. Recommendation 2 – Oleander Avenue & Boyle Avenue/Driveway 2 (#5) – The following improvements are necessary to accommodate site access: • Project to maintain the stop control on the westbound approach. • Project to accommodate shared left-through-right turn lane on westbound approach. Recommendation 3 – Oleander Avenue & Driveway 3 (#6) – The following improvements are necessary to accommodate site access: • Project to maintain the stop control on the westbound approach. • Project to accommodate shared left-right turn lane on westbound approach. Recommendation 4 – Driveway 4 & Slover Avenue (#8) – The following improvements are necessary to accommodate site access: • Project to install a stop control on the southbound approach (Project driveway) and a right turn lane. Driveway will be restricted to right-in/right-out access only with the construction of the future median along Slover Avenue. Recommendation 6 – Slover Avenue is an east-west oriented roadway located on the Project’s southern boundary. Project to construct Slover Avenue at its ultimate half-width as a Primary Highway (104-foot right-of-way) from Oleander Avenue to Cypress Avenue consistent with the City’s standards. Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 9 EXHIBIT 1-4: SITE ADJACENT ROADWAY AND SITE ACCESS RECOMMENDATIONS Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 10 Recommendation 7 – Oleander Avenue is a north-south oriented roadway located to the west of the Project (not on Project boundary). Project to widen the eastern curb on Oleander Avenue to accommodate 28-feet of pavement within a 44-foot right-of-way from the Project’s northern boundary to Slover Avenue consistent with the City’s standards. On-site traffic signing and striping should be implemented agreeable with the provisions of the California Manual on Uniform Traffic Control Devices (CA MUTCD) and in conjunction with detailed construction plans for the Project site. Sight distance at each project access point should be reviewed with respect to standard Caltrans and City of Fontana sight distance standards at the time of preparation of final grading, landscape, and street improvement plans. 1.6.2 OFF-SITE RECOMMENDATIONS Under Opening Year Cumulative (2023) With Project traffic conditions, two intersections are anticipated to have improvements due to net change in delay is more than the City’s thresholds for deficient study area intersections under pre-project traffic conditions. The Project would be required to pay fair share fees consistent with the City’s requirements (see Section 6 Local and Regional Funding Mechanisms).

See Table 6-1 for Fair Share Calculations. 5 Rough order of magnitude cost estimate. 6 Total project fair share contribution consists of the improvements which are not already included in a fee program for those intersections wholly or partially within the City. 7 Improvement requires the restriction of southbound U-turns. Fontana $204,255 Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 12 1.7 TRUCK ACCESS Due to the typical wide turning radius of large trucks, a truck turning template has been overlaid on the site plan at each applicable Project driveway anticipated to be utilized by heavy trucks in order to determine appropriate curb radii and to verify that trucks will have sufficient space to execute turning maneuvers (see Exhibit 1-5 for Oleander Avenue and Exhibit 1-6 for Slover Avenue). A WB-67 truck (53-foot trailer) has been utilized for the purposes of this analysis. As shown on Exhibit 1-5 and Exhibit 1-6, the following curb radius changes are necessary in order to accommodate the ingress and egress of heavy trucks: • Oleander Avenue at Driveway 1 should provide a 50-foot curb radius on the southeast corner. • Slover Avenue at Driveway 4 should provide a 50-foot curb radius on the northeast corner. 1.8 QUEUING ANALYSIS A queuing analysis was conducted along the site adjacent roadways of Oleander Avenue, Slover Avenue, and at the Project’s driveways for Opening Year Cumulative (2023) traffic conditions to determine the turn pocket lengths and lane geometric necessary to accommodate near-term 95th percentile queues and recommend storage lengths for the turning movements shown on Exhibit 1-4. The analysis was conducted for the weekday AM and weekday PM peak hours using the SimTraffic modeling software. The Opening Year Cumulative (2023) queuing results are provided in Table 1-5 and Appendix 5.6 of this TS. SimTraffic is designed to model networks of signalized and unsignalized intersections, with the primary purpose of checking and fine-tuning signal operations. SimTraffic uses the input parameters from Synchro (Version 11) to generate random simulations. The 95th percentile queue is not necessarily ever observed; it is simply based on statistical calculations (or Average Queue plus 1.65 standard deviations). The random simulations generated by SimTraffic have been utilized to determine the 95th percentile queue lengths observed for each turn lane. A SimTraffic simulation has been recorded 5 times, during the weekday AM and weekday PM peak hours, and has been seeded for 30-minute periods with 60-minute recording intervals.

As shown on Table 1-6, these segments are currently operating and are anticipated to continue to operate at acceptable LOS under Existing and Opening Year Cumulative conditions based on City’s Circulation Element roadway segment capacities. TABLE 1-6: SUMMARY OF ROADWAY SEGMENT CAPACITY ANALYSIS 1.10 VEHICLE MILES TRAVELED (VMT) ANALYSIS The Project was evaluated against City Guideline’s stated VMT screening criteria but was found to not meet available screening thresholds. As required by City Guidelines, a project level VMT analysis was performed consistent with the requirements identified for single use warehouse projects. The Project was not found to exceed 15% below the County of San Bernardino’s baseline regional average VMT per SP measures of VMT. The Project’s impact to VMT is therefore presumed to be less than significant. Detail traffic analysis can be found in Section 7 Vehicle Miles Traveled Analysis of this TS.

The methodologies described are generally consistent with the City of Fontana’s traffic study guidelines. (1) 2.1 LEVEL OF SERVICE Traffic operations of roadway facilities are described using the term "Level of Service" (LOS). LOS is a qualitative description of traffic flow based on several factors such as speed, travel time, delay, and freedom to maneuver. Six levels are typically defined ranging from LOS A, representing completely free-flow conditions, to LOS F, representing breakdown in flow resulting in stop-and-go conditions. LOS E represents operations at or near capacity, an unstable level where vehicles are operating with the minimum spacing for maintaining uniform flow. 2.2 INTERSECTION CAPACITY ANALYSIS The definitions of LOS for interrupted traffic flow (flow restrained by the existence of traffic signals and other traffic control devices) differ slightly depending on the type of traffic control. The LOS is typically dependent on the quality of traffic flow at the intersections along a roadway. The Highway Capacity Manual (HCM) methodology expresses the LOS at an intersection in terms of delay time for the various intersection approaches. (5) The HCM uses different procedures depending on the type of intersection control. 2.2.1 SIGNALIZED INTERSECTIONS The City of Fontana requires signalized intersection operations analysis based on the methodology described in the HCM (6th Edition). Intersection LOS operations are based on an intersection’s average control delay. Control delay includes initial deceleration delay, queue move-up time, stopped delay, and final acceleration delay. For signalized intersections, LOS is directly related to the average control delay per vehicle and is correlated to a LOS designation as described in Table 2-1. Study area intersections have been evaluated using the Synchro (Version 11) analysis software package. The traffic modeling and signal timing optimization software package Synchro (Version 11) is utilized to analyze signalized intersections within the study area. Synchro is a macroscopic traffic software program that is based on the signalized intersection capacity analysis as specified in the HCM. Macroscopic level models represent traffic in terms of aggregate measures for each movement at the study intersections. Equations are used to determine measures of effectiveness such as delay and queue length. The level of service and capacity analysis performed by Synchro takes into consideration optimization and coordination of signalized intersections within a network. Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 18 TABLE 2-1: SIGNALIZED INTERSECTION LOS THRESHOLDS Description Average Control Delay (Seconds), V/C ≤ 1.0 Level of Service, V/C ≤ 1.0 Level of Service, V/C > 1.0 Operations with very low delay occurring with favorable progression and/or short cycle length. 0 to 10.00 A F Operations with low delay occurring with good progression and/or short cycle lengths. 10.01 to 20.00 B F Operations with average delays resulting from fair progression and/or longer cycle lengths. Individual cycle failures begin to appear. 20.01 to 35.00 C F Operations with longer delays due to a combination of unfavorable progression, long cycle lengths, or high V/C ratios. Many vehicles stop and individual cycle failures are noticeable. 35.01 to 55.00 D F Operations with high delay values indicating poor progression, long cycle lengths, and high V/C ratios. Individual cycle failures are frequent occurrences. This is considered to be the limit of acceptable delay. 55.01 to 80.00 E F Operation with delays unacceptable to most drivers occurring due to over saturation, poor progression, or very long cycle lengths 80.01 and up F F Source: HCM, 6th Edition A saturation flow rate of 1900 has been utilized for all study area intersections located within the City of Fontana. The peak hour traffic volumes are adjusted using a peak hour factor (PHF) to reflect peak 15-minute volumes. Common practice for LOS analysis is to use a peak 15-minute rate of flow. However, flow rates are typically expressed in vehicles per hour. The PHF is the relationship between the peak 15-minute flow rate and the full hourly volume (e.g., PHF = [Hourly Volume] / [4 x Peak 15-minute Flow Rate]). The use of a 15-minute PHF produces a more detailed analysis as compared to analyzing vehicles per hour. Existing PHFs have been used for all analysis scenarios. Per the HCM, PHF values over 0.95 often are indicative of high traffic volumes with capacity constraints on peak hour flows while lower PHF values are indicative of greater variability of flow during the peak hour. (5) 2.2.2 UNSIGNALIZED INTERSECTIONS The City of Fontana require the operations of unsignalized intersections be evaluated using the methodology described the HCM. (5) The LOS rating is based on the weighted average control delay expressed in seconds per vehicle (see Table 2-2). Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 19 TABLE 2-2: UNSIGNALIZED INTERSECTION LOS THRESHOLDS Description Average Control Delay Per Vehicle (Seconds) Level of Service, V/C ≤ 1.0 Level of Service, V/C > 1.0 Little or no delays. 0 to 10.00 A F Short traffic delays. 10.01 to 15.00 B F Average traffic delays. 15.01 to 25.00 C F Long traffic delays. 25.01 to 35.00 D F Very long traffic delays. 35.01 to 50.00 E F Extreme traffic delays with intersection capacity exceeded. > 50.00 F F Source: HCM, 6th Edition At two-way or side-street stop-controlled intersections, LOS is calculated for each controlled movement and for the left turn movement from the major street, as well as for the intersection as a whole. For approaches composed of a single lane, the delay is computed as the average of all movements in that lane. Per the HCM, the highest delay and associated LOS on the minor approach is reported for two-way stop-controlled intersections. For all-way stop controlled intersections, LOS is computed for the intersection as a whole and the average delay is reported (similar to signalized intersections). 2.3 ROADWAY SEGMENT CAPACITY ANALYSIS METHODOLOGY Roadway segment operations have been evaluated using the applicable average daily traffic (ADT) roadway capacity values provided in the City of Fontana General Plan. The roadway capacities utilized for the purposes of this analysis are considered “rule of thumb” estimates for planning purposes and are affected by such factors as intersections (spacing, configuration and control features), degree of access control, roadway grades, design geometrics (horizontal and vertical alignment standards), sight distance, vehicle mix (truck and bus traffic) and pedestrian bicycle traffic. The City of Fontana Circulation Element identifies 9,000 vehicles per lane per day for divided arterials. While using ADT for planning purposes is suitable with regards to evaluating potential volume to capacity with future forecasts, it is not suitable for operational analysis because it does not account for the factors listed previously. As such, where the ADT based roadway segment analysis indicates a deficiency (unacceptable LOS), a review of the more detailed peak hour intersection analysis and progression analysis are undertaken. The more detailed peak hour intersection analysis explicitly accounts for factors that affect roadway capacity. Therefore, roadway segment widening is typically only recommended if the peak hour intersection analysis indicates the need for additional through lanes. Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 20 2.4 TRAFFIC SIGNAL WARRANT ANALYSIS METHODOLOGY The term "signal warrants" refers to the list of established criteria used by the Caltrans and other public agencies to quantitatively justify or ascertain the potential need for installation of a traffic signal at an otherwise unsignalized intersection. This TS uses the signal warrant criteria presented in the latest edition of the Caltrans California Manual on Uniform Traffic Control Devices (CA MUTCD). (6) The signal warrant criteria for Existing conditions are based upon several factors, including volume of vehicular and pedestrian traffic, frequency of accidents, and location of school areas. The Caltrans CA MUTCD indicates that the installation of a traffic signal should be considered if one or more of the signal warrants are met. (6) Specifically, this TS utilizes the Peak Hour Volume- based Warrant 3 as the appropriate representative traffic signal warrant analysis for existing study area intersections for all analysis scenarios. Warrant 3 is appropriate to use for this TS because it provides specialized warrant criteria for intersections with rural characteristics (e.g., located in communities with populations of less than 10,000 persons or with adjacent major streets operating above 40 miles per hour). For the purposes of this study, the speed limit was the basis for determining whether Urban or Rural warrants were used for a given intersection. Traffic signal warrant analyses were performed for the following unsignalized study area intersection shown in Table 2-3: TABLE 2-3: TRAFFIC SIGNAL WARRANT ANALYSIS LOCATIONS ID Intersection Location Jurisdiction 5 Oleander Av. & Boyle Av. Fontana 11 Juniper Av. & Slover Av. Fontana The Existing conditions traffic signal warrant analysis is presented in the subsequent section, Section 3 Area Conditions of this report. The traffic signal warrant analyses for future conditions are presented in Section 5 Opening Year Cumulative (2023) Traffic Conditions of this report. It is important to note that a signal warrant defines the minimum condition under which the installation of a traffic signal might be warranted. Meeting this threshold condition does not require that a traffic control signal be installed at a particular location, but rather, that other traffic factors and conditions be evaluated in order to determine whether the signal is truly justified. It should also be noted that signal warrants do not necessarily correlate with LOS. An intersection may satisfy a signal warrant condition and operate at or above acceptable LOS or operate below acceptable LOS and not meet a signal warrant. Traffic signal warrant analysis has not been performed for unsignalized intersections with limited access/turn restrictions. Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 21 2.5 MINIMUM LEVEL OF SERVICE (LOS) The City’s General Plan recommends a LOS standard of LOS C. Intersections which are forecast to operate at unsatisfactory conditions (i.e., at LOS worse than LOS C for City intersections) shall be identified as cumulatively deficient intersections. Therefore, any intersection operating at LOS D, E, or F will be considered deficient for the purposes of this analysis. (1) 2.6 DEFICIENCY CRITERIA For the intersections that lie within the City of Fontana, determination of direct project-related deficiencies will be based on a comparison of without and with project levels of service for each analysis year. A project-related deficiency occurs if project traffic increases the average delay at an intersection by more than the thresholds identified on Table 2-4. The thresholds for LOS A, B, and C do not apply to projects consistent with the General Plan. TABLE 2-4: THRESHOLDS OF SIGNIFICANT IMPACT A Project’s contribution to a deficiency can be reduced/improved if the Project is required to implement or fund its fair share of improvements designed to alleviate the potential deficiency. 2.7 PROJECT FAIR SHARE CALCULATION METHODOLOGY In cases where this TS identifies that the proposed Project would have a significant cumulative impact to a roadway facility, and the recommended mitigation measure is a fair share monetary contribution, the following methodology was applied to determine the fair share contribution. A project’s fair share contribution at an off-site study area intersection is determined based on the following equation, which is the ratio of Project traffic to net new traffic, where net new traffic is total future traffic (Opening Year Cumulative conditions) subtracts less baseline traffic: Project Fair Share % = Project Traffic / (Opening Year Cumulative Total Traffic – Existing Baseline Traffic) The Project fair share contribution calculations are presented in Section 6 Local and Regional Funding Mechanisms of this TS.

Exhibit 3-1 illustrates the study area intersections located near the proposed Project and identifies the number of through traffic lanes for existing roadways and intersection traffic controls. 3.2 GENERAL PLAN CIRCULATION ELEMENTS As noted previously, the Project site is located within the City of Fontana. The roadway classifications and planned (ultimate) roadway cross-sections of the major roadways within the study area, as identified on City of Fontana General Plan Hierarchy of Streets, are described subsequently. Exhibit 3-2 shows the City of Fontana General Plan Circulation Element. The City of Fontana General Plan does not include roadway cross-sections in its General Plan. Major Highways are four-to-six-lane divided roadways (typically divided by a raised median or painted two-way turn-lane). These roadways serve both regional through-traffic and inter-city traffic and typically direct traffic onto and off-of the freeways. The following study area roadway within the City of Fontana is classified as a Major Highways: • Citrus Avenue, north of Slover Avenue Primary Highways are four-lane roadways and may include a painted median. These roadways typically direct traffic through major development areas. The following study area roadway within the City of Fontana is classified as a Primary Highways: • Slover Avenue Secondary Highways are two-lane streets, providing one lane in each direction, separated by a raised median. The following study area roadways within the study area are classified as a Secondary Highways: • Citrus Avenue, south of Slover Avenue • Cypress Avenue Collector Streets are two-lane streets, providing one lane in each direction. The following study area roadway within the study area is classified as a Collector Street: • Oleander Avenue, south of Slover Avenue • Juniper Avenue, south of Slover Avenue Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 24 EXHIBIT 3-1: EXISTING NUMBER OF THROUGH LANES AND INTERSECTION CONTROL Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 25 EXHIBIT 3-2: CITY OF FONTANA HIERARCHY OF STREETS Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 26 3.3 TRUCK ROUTES Exhibit 3-3 shows the City of Fontana truck routes. As shown, Citrus Avenue and Slover Avenue are identified as truck routes. These truck routes have been utilized to route truck traffic associated with the proposed Project and future cumulative development projects for the purposes of this TS. 3.4 BICYCLE & PEDESTRIAN FACILITIES The City of Fontana bike facilities are shown on Exhibit 3-4. There are no existing bike facilities within the study area. However, Citrus Avenue and Cypress Avenue are proposed Class II bike facilities. Exhibit 3-5 illustrates the existing pedestrian facilities, including sidewalks and crosswalks. As shown on Exhibit 3-5, there are limited pedestrian facilities within the study area. 3.5 TRANSIT SERVICE The study area is currently served by Omnitrans Transit Agency with bus services along Citrus Avenue and Slover Avenue via Omnitrans Route 82. There are currently stops along Slover Avenue in close proximity to the proposed Project. The transit services are illustrated on Exhibit 3-6. Transit service is reviewed and updated by Omnitrans periodically to address ridership, budget, and community demand needs. Changes in land use can affect these periodic adjustments which may lead to either enhanced or reduced service where appropriate. 3.6 EXISTING TRAFFIC COUNTS The intersection LOS analysis is based on the traffic volumes observed during the peak hour conditions using traffic count data collected in May 2018, March 2019, April 2021, and August 2021. The following peak hours were selected for analysis: • Weekday AM Peak Hour (peak hour between 7:00 AM and 9:00 AM) • Weekday PM Peak Hour (peak hour between 4:00 PM and 6:00 PM) Due to the currently ongoing COVID-19 pandemic, schools and businesses within the study area were closed or operating at less than full capacity at the time this study was prepared. As such, historic traffic counts from May 2018 and March 2019 were utilized in conjunction with a 1.16% per year growth rate (compounded annually) to develop traffic volumes for 2021 conditions. The historic weekday AM and weekday PM peak hour count data is representative of typical weekday peak hour traffic conditions in the study area. There were no observations made in the field that would indicate atypical traffic conditions on the count dates, such as construction activity or detour routes and near-by schools were in session and operating on normal schedules.

As such, 2021 traffic counts have been collected at the intersections of Oleander Avenue at Boyle Avenue. Traffic counts have also been collected at Citrus Avenue at I-10 Westbound Ramps, Citrus Avenue at I-10 Eastbound Ramps, and Oleander Avenue at Slover Avenue in order to compare and develop an adjustment factor based on a comparison to historic May 2018 or March 2019 traffic count data to the recently collected 2021 traffic count data. This adjustment factor has been applied to the 2021 traffic count data at the intersection of Oleander Avenue and Boyle Avenue in order to reflect non-COVID traffic conditions. Where applicable, traffic volumes have been flow conserved in order to not have any loss of vehicles. The raw manual peak hour turning movement traffic count data sheets are included in Appendix 3.1. Existing weekday ADT volumes on arterial highways throughout the study area are shown on Exhibit 3-7. Where actual 24-hour tube count data was not available, Existing ADT volumes were based upon factored intersection peak hour counts collected by Urban Crossroads, Inc. using the following formula for each intersection leg: Weekday PM Peak Hour (Approach Volume + Exit Volume) x 10.38 = Leg Volume A comparison of the PM peak hour and daily traffic volumes of various roadway segments within the study area indicated that the peak-to-daily relationship is approximately 9.63 percent. As such, the above equation utilizing a factor of 10.38 estimates the ADT volumes on the study area roadway segments assuming a peak-to-daily relationship of approximately 9.63 percent (i.e., 1/0.0963 = 10.38) and was assumed to sufficiently estimate ADT volumes for planning-level analyses. Existing weekday AM and weekday PM peak hour intersection volumes are shown on Exhibit 3-7. The volumes shown on Exhibit 3-7 (and on all other volume exhibits within this report) are in actual vehicles. PCE volumes utilized in the operations analysis are provided in the appendices for each applicable analysis scenario.

The Project is anticipated to be developed within a single phase with an Opening Year of 2023. As shown on Exhibit 1-2, access to the Project site will be provided to Oleander Avenue via 3 full access driveways and to Slover Avenue via 1 driveway. A future raised median is planned to be constructed along Slover Avenue between Oleander Avenue and Cypress Avenue. As such, Driveway 4 is proposed to be restricted to right-in/right-out access only. Regional access to the Project site is available from the I-10 Freeway via the Citrus Avenue and Sierra Avenue interchanges. 4.1 PROJECT TRIP GENERATION In order to develop the traffic characteristics of the proposed project, trip-generation statistics published in the Institute of Transportation Engineers (ITE) Trip Generation Manual (11th Edition, 2017) for High-Cube Cold Storage Warehouse (Land Use Code 157) and the High-Cube Warehouse Trip Generation Study (WSP, January 29, 2019) for High-Cube Fulfillment Center Warehouse use. (2) (3) The ITE Trip Generation Manual Supplement (February 2020) has trip generation rates for high- cube fulfillment center use for both non-sort and sort facilities (ITE land use code 155). (7) While there is sufficient data to support use of the trip generation rates for non-sort facilities, the sort facility rate appears to be unreliable because they are based on limited data (i.e., one to two surveyed sites only). The proposed Project is speculative and whether a non-sort or sort facility end-user would occupy the building is not known at this time. Lastly, the ITE Trip Generation Manual recommends the use of local data sources where available. As such, the best available source for high-cube fulfilment center use would be the trip-generation statistics published in the High-Cube Warehouse Trip Generation Study (WSP, January 29, 2019) which was commissioned by the Western Riverside Council of Governments (WRCOG) in support of the Transportation Uniform Mitigation Fee (TUMF) update in the County of Riverside. (3) The WSP trip generation rates were published in January 2019 and are based on data collected at 11 local high-cube fulfillment center sites located throughout Southern California (located throughout both Riverside County and San Bernardino County).

Trip distribution is the process of identifying the probable destinations, directions or traffic routes that will be utilized by Project traffic. The potential interaction between the planned land uses and surrounding regional access routes are considered, to identify the route where the Project traffic would distribute. Separate distributions have been developed for passenger cars and trucks. Exhibits 4-1 and 4-2 illustrate the passenger car and truck trip distribution patterns through the study area intersections, respectively. 4.3 MODAL SPLIT The traffic reducing potential of public transit, walking, or bicycling have not been considered in this TS. Essentially, the traffic projections are "conservative" in that these alternative travel modes might be able to reduce the forecasted traffic volumes. 4.4 PROJECT TRIP ASSIGNMENT The assignment of traffic from the Project area to the adjoining roadway system is based upon the Project trip generation, trip distribution, and the arterial highway and local street system improvements that would be in place by the time of initial occupancy of the Project. Based on the identified Project traffic generation and trip distribution patterns, the Project only ADT and peak hour intersection turning movement volumes are shown on Exhibit 4-3.

The total ambient growth is 2.33% for 2023 traffic conditions (compounded growth of 1.16 percent per year over 2 years or 1.01162 years). The ambient growth factor is intended to approximate regional traffic growth. This ambient growth rate is added to existing traffic volumes to account for area-wide growth not reflected by cumulative development projects. Ambient growth has been added to daily and peak hour traffic volumes on surrounding roadways, in addition to traffic generated by the development of future projects that have been approved but not yet built and/or for which development applications have been filed and are under consideration by governing agencies. Opening Year Cumulative (2023) traffic volumes are provided in Section 5 of this TS. The traffic generated by the proposed Project was then manually added to the base volume to determine Opening Year Cumulative “With Project” forecasts. 4.6 CUMULATIVE DEVELOPMENT TRAFFIC A cumulative project list was developed for the purposes of this analysis through consultation with planning and engineering staff from the City of Fontana. The cumulative project list includes known and foreseeable projects that are anticipated to contribute traffic to the study area intersections. Where applicable, cumulative projects anticipated to contribute measurable traffic (i.e., 50 or more peak hour trips) to study area intersections have been manually added to the study area network to generate Opening Year Cumulative (2023) forecasts. In other words, this list of cumulative development projects has been reviewed to determine which projects would likely contribute measurable traffic through the study area intersections (e.g., those cumulative projects in close proximity to the proposed Project). For the purposes of this analysis, the cumulative projects that were determined to affect one or more of the study area intersections are shown on Exhibit 4-4, listed in Table 4-4, and have been considered for inclusion. Although it is unlikely that all of these cumulative projects would be fully built and occupied by Years 2023, they have been included in an effort to conduct a conservative analysis and overstate as opposed to understate potential traffic deficiencies. Any other cumulative projects located beyond the cumulative study area that are not expected to contribute measurable traffic to study area intersections have not been included since the traffic would dissipate due to the distance from the Project site and study area intersections. Any additional traffic generated by other projects not on the cumulative projects list is likely accounted for through background ambient growth factors that have been applied to the peak hour volumes at study area intersections as discussed in Section 4.5 Background Traffic. Cumulative Only ADT and peak hour intersection turning movement volumes are shown on Exhibit 4-5.

An ambient growth factor of 1.16% per year, compounded annually, accounts for background (area-wide) traffic increases that occur over time up to the years 2023 from the year 2021. Traffic volumes generated by cumulative development projects are then added to assess the Opening Year Cumulative (2023) traffic conditions. Lastly, Project traffic is added to assess “With Project” traffic conditions. The 2023 roadway network is similar to the existing conditions roadway network with the exception of intersections proposed to be developed by the Project. The near-term traffic analysis includes the following traffic conditions, with the various traffic components: • Opening Year Cumulative (2023) Without Project o Adjusted Existing 2021 counts o Ambient growth traffic (2.33%) o Cumulative Development Project traffic • Opening Year Cumulative (2023) With Project o Adjusted Existing 2021 counts o Ambient growth traffic (2.33%) o Cumulative Development Project traffic o Project traffic Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 48 This Page Intentionally Left Blank Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 49 5 OPENING YEAR CUMULATIVE (2023) TRAFFIC CONDITIONS This section discusses the methods used to develop Opening Year Cumulative (2023) Without and With Project traffic forecasts, and the resulting intersection operations, roadway segment, and traffic signal warrant analyses. 5.1 ROADWAY IMPROVEMENTS The lane configurations and traffic controls assumed to be in place for Opening Year Cumulative (2023) conditions are consistent with those shown previously on Exhibit 3-1, with the exception of the following: • Project driveways and those facilities assumed to be constructed by the Project to provide site access are also assumed to be in place for Opening Year Cumulative conditions only (e.g., intersection and roadway improvements along the Project’s frontage and driveways). • Driveways and those facilities assumed to be constructed by cumulative developments to provide site access are also assumed to be in place for Opening Year Cumulative conditions only (e.g., intersection and roadway improvements along the cumulative development’s frontages and driveways). 5.2 OPENING YEAR CUMULATIVE (2023) WITHOUT PROJECT TRAFFIC VOLUME FORECASTS This scenario includes Existing traffic volumes plus an ambient growth factor of 2.33% plus traffic from pending and approved but not yet constructed known development projects in the area.

There are no unsignalized study area intersections anticipated to meet a traffic signal warrant under Opening Year Cumulative (2023) Without Project or With Project traffic conditions (see Appendix 5.3 and 5.4). 5.6 ROADWAY SEGMENT ANALYSIS The roadway segment capacities are approximate figures only and are used at the General Plan level to assist in determining the roadway functional classification (number of through lanes) needed to meet traffic demand. Table 5-2 provides a summary of the Opening Year Cumulative conditions roadway segment capacity analysis based on the City of Fontana Roadway Segment Capacity Thresholds. As shown on Table 5-2, the study area roadway segments are anticipated to continue to operate at an acceptable LOS based on the City’s planning level daily roadway capacity thresholds, consistent with Existing (2021) traffic conditions.

Improvements might require additional right-of-way/ramp widening. Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 55 6 LOCAL AND REGIONAL FUNDING MECHANISMS Transportation improvements within the City of Fontana are funded through a combination of direct project mitigation, development impact fee programs or fair share contributions, such as the City of Fontana DIF program. Identification and timing of needed improvements is generally determined through local jurisdictions based upon a variety of factors. 6.1 MEASURE “I” FUNDS In 2004, the voters of San Bernardino County approved the 30-year extension of Measure “I”, a one-half of one percent sales tax on retail transactions, through the year 2040, for transportation projects including, but not limited to, infrastructure improvements, commuter rail, public transit, and other identified improvements. The Measure “I” extension requires that a regional traffic impact fee be created to ensure development is paying its fair share. A regional Nexus study was prepared by SBCTA and concluded that each jurisdiction should include a regional fee component in their local programs in order to meet the Measure “I” requirement. The regional component assigns specific facilities and cost sharing formulas to each jurisdiction and was most recently updated in May 2018. Revenues collected through these programs are used in tandem with Measure “I” funds to deliver projects identified in the Nexus Study. While Measure “I” is a self-executing sales tax administered by SBCTA, it bears discussion here because the funds raised through Measure “I” have funded in the past and will continue to fund new transportation facilities in San Bernardino County, including within the City of Fontana. 6.2 CITY OF FONTANA DEVELOPMENT IMPACT FEE (DIF) The City of Fontana adopted the latest update to their DIF program in February 2016. Fees from new residential, commercial and industrial development are collected to fund Measure “I” compliant regional facilities as well as local facilities. Under the City’s DIF program, the City may grant to developers a credit against specific components of fees when those developers construct certain facilities and landscaped medians identified in the list of improvements funded by the DIF program. After the City’s DIF fees are collected, they are placed in a separate restricted use account pursuant to the requirements of Government Code sections 66000 et seq. The timing to use the DIF fees is established through periodic capital improvement programs which are overseen by the City’s Engineering Department. Periodic traffic counts, review of traffic accidents, and a review of traffic trends throughout the City are also periodically performed by City staff and consultants. The City uses this data to determine the timing of the improvements listed in its facilities list. The City also uses this data to ensure that the improvements listed on the facilities list are constructed before the LOS falls below the LOS performance standards adopted by the City. In this way, the improvements are constructed before the LOS falls below the City’s LOS performance thresholds. The City’s DIF program establishes a timeline to fund, design, and build the improvements. Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 56 6.3 FAIR SHARE CONTRIBUTION Project improvement may include a combination of fee payments to established programs, construction of specific improvements, payment of a fair share contribution toward future improvements or a combination of these approaches. Improvements constructed by development may be eligible for a fee credit or reimbursement through the program where appropriate (to be determined at the City’s discretion). When off-site improvements are identified with a minor share of responsibility assigned to proposed development, the approving jurisdiction may elect to collect a fair share contribution or require the development to construct improvements. Detailed fair share calculations, for each peak hour, has been provided on Table 6-1 for the applicable deficient study area intersections. These fees are collected with the proceeds solely used as part of a funding mechanism aimed at ensuring that regional highways and arterial expansions keep pace with the projected population increases.

Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 57 7 VEHICLE MILES TRAVELED Changes to California Environmental Quality Act (CEQA) Guidelines were adopted in December 2018, which require all lead agencies to adopt VMT as a replacement for automobile delay-based level of service (LOS) as the measure for identifying transportation impacts for land use projects. This statewide mandate went into effect July 1, 2020. To aid in this transition, the Governor’s Office of Planning and Research (OPR) released a Technical Advisory on Evaluating Transportation Impacts in CEQA (December of 2018) (Technical Advisory). (8) Based on OPR’s Technical Advisory, the City of Fontana adopted its Traffic Impact Analysis Guidelines for Vehicle Miles Traveled and Level of Service Assessment (October of 2020) (9) (City Guidelines), which documents the City’s VMT analysis methodology and approved impact thresholds. The VMT analysis presented in this report has been developed based on the adopted City Guidelines. 7.1 PROJECT SCREENING The City Guidelines provides information on appropriate screening thresholds that can be used to identify when a proposed land use project is anticipated to result in a less than significant impact without conducting a more detailed project-level assessment. Screening thresholds are broken into the following four steps: • Step 1: Transit Priority Area (TPA) Screening • Step 2: Low VMT Area Screening • Step 3: Low Project Type Screening • Step 4: Project net daily trips less than 500 ADT The City Guidelines identify that the SBCTA VMT Screening Tool (Screening Tool) is utilized to assess project VMT screening criteria. The Screening Tool uses the project’s assessor’s parcel number (APN) to determine if its location meets one or more of the VMT screening thresholds for land use projects. A land use project need only meet one of the above screening criteria to result in a less than significant impact. 7.1.1 STEP 1: TPA SCREENING Consistent with guidance identified in the City Guidelines, projects located within a Transit Priority Area (TPA) (i.e., within ½ mile of an existing “major transit stop”1 or an existing stop along a “high-quality transit corridor”2) may be presumed to have a less than significant impact absent substantial evidence to the contrary. However, the presumption may NOT be appropriate if a project: 1 Pub. Resources Code, § 21064.3 (“‘Major transit stop’ means a site containing an existing rail transit station, a ferry terminal served by either a bus or rail transit service, or the intersection of two or more major bus routes with a frequency of service interval of 15 minutes or less during the morning and afternoon peak commute periods.”). 2 Pub. Resources Code, § 21155 (“For purposes of this section, a high-quality transit corridor means a corridor with fixed route bus service with service intervals no longer than 15 minutes during peak commute hours.”). Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 58 • Has a Floor Area Ratio (FAR) of less than 0.75; • Includes more parking for use by residents, customers, or employees of the project than required by the jurisdiction (if the jurisdiction requires the project to supply parking); • Is inconsistent with the applicable Sustainable Communities Strategy (as determined by the lead agency, with input from the Metropolitan Planning Organization); or • Replaces affordable residential units with a smaller number of moderate- or high-income residential units. Based on the Screening Tool results presented in Appendix 7.1, the Project site is not located within ½ mile of an existing major transit stop, or along a high-quality transit corridor. TPA screening criteria is not met. 7.1.2 STEP 2: LOW VMT AREA SCREENING As described in the City Guidelines, “residential and office projects located within a low VMT generating area may be presumed to have a less than significant impact absent substantial evidence to the contrary. In addition, other employment-related and mixed-use land use projects may qualify for the use of screening if the project can reasonably be expected to generate VMT per resident, per worker, or per service population that is similar to the existing land uses in the low VMT area.” The Screening Tool uses the sub-regional San Bernardino Transportation Analysis Model (SBTAM) to measure VMT performance within individual traffic analysis zones (TAZ’s) within the City. The Project’s physical location based on parcel number is selected in the Screening Tool to determine project generated VMT as compared to the City’s threshold. The parcel containing the proposed Project was selected and the Screening Tool was run for the Production/Attraction (PA) VMT per service population measure of VMT. The Project is not located within a low VMT generating zone as compared to the City threshold of 15% below baseline County of San Bernardino PA VMT per service population (see Appendix 7.1). Low VMT Area screening criteria is not met. 7.1.3 STEP 3: LOW PROJECT TYPE SCREENING City Guidelines state that local serving retail projects less than 50,000 square feet may be presumed to have a less than significant impact. In addition to local serving retail, other local serving land uses such as public facilities, day care centers, gas stations, etc. would tend to provide local services and result in reducing overall VMT. The Project’s intended land use does not include any local serving retail. Project Type screening criteria is not met. 7.1.4 STEP 4: PROJECT NET DAILY TRIPS LESS THAN 500 ADT SCREENING Identified in City Guidelines, Projects that generate fewer than 500 average daily trips (ADT) would not cause a substantial increase in the total citywide or regional VMT and are therefore Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 59 presumed to have less than significant impact on VMT. Trips generated by the Project’s proposed land use have been estimated based on trip generation rates collected by the Institute of Transportation Engineers (ITE) Trip Generation Manual, 11th Edition, 2021. (2) The proposed Project is anticipated to generate a total of 1,334 vehicle trip-ends per day, exceeding 500 average daily trips criteria (see Table 4-2). Project Net Daily Trips Screening criteria is not met. The project was not found to meet any of the aforementioned VMT screening criteria, a project level VMT analysis should be prepared. 7.2 VMT METHODOLOGY Consistent with City Guidelines, the San Bernardino Transportation Analysis Model (SBTAM) is a useful tool to estimate VMT as it considers interaction between different land uses based on socio-economic data such as population, households, and employment. The City Guidelines identifies SBTAM as the appropriate tool for conducting VMT analysis for land use projects in the City of Fontana. 7.3 VMT ANALYSIS Project VMT has been calculated using the most current version of SBTAM. Adjustments to socio- economic data (SED) (i.e., the Project’s estimated number of employees) has been made to the appropriate traffic analysis zone (TAZ) within the SBTAM model to reflect the Project’s proposed land use (i.e., warehouse). Table 7-1 summarizes the employment estimates for the Project. It should be noted that the employment estimates are consistent with the employment density factors identified in the Southern California Association of Governments (SCAG) Employment Density Study (October 2001). (4) TABLE 7-1: EMPLOYMENT ESTIMATES Land Use Quantity (SF) Employment Density Factor3 Estimated Employees Warehouse 625,460 1 employee per 1,195 SF 524 SED adjustments to represent the Project were made to the applicable TAZ in both the SBTAM base year and cumulative year traffic models. The SBTAM base year and cumulative year travel demand forecasting models inclusive of Project SED were run and Project generated VMT was then calculated from the production attraction (PA) trip matrices – consistent with City Guidelines for single land use projects. Project generated total VMT is then normalized by dividing by the Project’s SP (i.e., Project employees). The project generated VMT, for both the base year model (2016) and cumulative year model (2040) results, were then calculated utilizing linear interpolation to determine the baseline (2021) project generated VMT. As shown in Table 7-2, the Project baseline VMT per SP is 20.64. 3 Table II-B of the SCAG Employment Density Study. Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 60 TABLE 7-2: PROJECT VMT PER SP Base Year (2016) Cumulative (2040) Baseline (2021) VMT 10,873 10,606 10,815 Employment 524 524 524 VMT per SP4 20.75 20.24 20.64 7.3.1 REGIONAL VMT The City Guidelines provides the following impact threshold(s) used to determine a projects impact on VMT. A project would result in a significant project generated impact if either of the following conditions are satisfied: 1. The baseline project generated VMT per service population exceeds 15% below the baseline County of San Bernardino VMT per service population (SP), or 2. The cumulative project generated VMT per service population exceeds 15% below the baseline County of San Bernardino VMT per SP. As noted, the City’s adopted VMT impact threshold is based on a level of 15% below the baseline County of San Bernardino VMT per SP. SBCTA provides VMT calculations for each of its member agencies and for the County of San Bernardino region. Urban Crossroads has obtained from SBCTA the baseline PA VMT per SP value for the County of San Bernardino, which is 28.37. The City’s adopted threshold is a value of 15% below the baseline County of San Bernardino VMT per SP or 24.11 VMT per SP. 7.3.2 PROJECT LEVEL VMT ASSESSMENT Table 7-3 illustrates the comparison between Project baseline and cumulative VMT per SP to the City’s adopted impact threshold. As indicated, the Project baseline and cumulative VMT per SP are below the City’s adopted impact threshold; in other words, the Project VMT impact is less than significant. TABLE 7-3: PROJECT VMT PER SP COMPARISON Baseline (2021) Cumulative (2040) Impact Threshold 24.11 24.11 Project 20.64 20.24 Potentially Significant? No No 7.3.3 PROJECT’S CUMULATIVE IMPACT ON VMT The Technical Advisory notes that “… metrics such as VMT per capita or VMT per employee, i.e., metrics framed in terms of efficiency (as recommended below for use on residential and office projects), cannot be summed because they employ a denominator. A project that falls below an efficiency-based threshold that is aligned with long-term goals and relevant plans has no cumulative impact distinct from the project impact. Accordingly, a finding of a less-than- 4 Since the Project does not have a residential component, the service population consists entirely of employment. Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 61 significant project impact would imply a less than significant cumulative impact, and vice versa. This is similar to the analysis typically conducted for greenhouse gas emissions, air quality impacts, and impact that utilize plan compliance as a threshold of significance.”7 As the Project was found to have a less than significant impact based on the efficiency metric VMT per service population, the Project’s cumulative impact is also considered less than significant. . The Project was evaluated against City Guideline’s stated VMT screening criteria but was found to not meet available screening thresholds. As required by City Guidelines, a project level VMT analysis was performed consistent with the requirements identified for single use warehouse projects. The Project was not found to exceed 15% below the County of San Bernardino’s baseline regional average VMT per SP measures of VMT. The Project’s impact to VMT is therefore presumed to be less than significant. 7 OPR’s Technical Advisory; Page 6 Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 62 This Page Intentionally Left Blank Slover Avenue & Cypress Avenue Warehouse Traffic Study 13921-07 TS Report 63 8 REFERENCES 1.
