The following technical memorandum provides a trip generation and vehicle miles traveled (VMT) screening analysis
of the proposed 11700 Industry Avenue Warehouse (project) in the City of Fontana (City). The project site is located
in Jurupa South Industrial District of the Southwest Industrial Park (SWIP) Specific Plan area. This analysis was
conducted to determine the trip generation and VMT estimates of the proposed project and determine whether the
proposed project would be consistent with the SWIP Program Environmental Impact Report (City of Fontana 2011). This
analysis has been prepared consistent with the trip generation methodology from the Institute of Transportation
Engineers (ITE 2021) and VMT estimation methodology per the City of Fontana (City of Fontana 2020).
Per Senate Bill 743, the Governor’s Office of Planning and Research was directed to amend the California
Environmental Quality Act (CEQA) Guidelines to provide an alternative to level of service (LOS) for evaluating
transportation impacts. CEQA Guidelines Section 15064.3(b) focuses on specific criteria (VMT) for determining the
significance of transportation impacts. Under the new transportation guidelines, LOS, or vehicle delay, does not
constitute an environmental impact. VMT has been adopted as the most appropriate measure of transportation
impacts under CEQA.
The City has adopted the use of the VMT metric and has significance criteria for transportation impacts related to
VMT. Additionally, the City still requires LOS analysis for General Plan consistency requirements. The following
analysis has been prepared consistent with the City’s Traffic Impact Analysis (TIA) Guidelines for Vehicle Miles
Traveled and Level of Service Assessment (City of Fontana 2020), which provides guidance on the requirements to
evaluate transportation impacts for projects. This analysis was conducted to determine the trip generation
estimates and VMT screening analysis of the proposed project, and to determine whether a detailed transportation
analysis (LOS and/or VMT) would be required for the proposed project.

As shown in the screening analysis below, the proposed project would not require a Traffic Impact Analysis (TIA) or
further VMT analysis. The City’s scoping agreement form to support the LOS screening is attached to this
memorandum (Attachment A).
1 Project Description
The project would include construction of a warehouse building of approximately 124,000 square feet (inclusive of
5,000 square feet of office spaces and 5,000 square feet of mezzanine) located at 11700 Industry Avenue in the
City. Figure 1 illustrates the project’s location. The project site is approximately 6.00 acres and contains an existing
industrial use building of approximately 108,000 square feet. The proposed project would replace existing industrial
use that is currently operational on the project site.
The City General Plan Land Use Map designates the project site as General Industrial (I-G) (City of Fontana 2021a),
and the City’s Zoning Map shows the site as being zoned as the SWIP Specific Plan (SP) zone (City of Fontana
2021b) (within the SWIP SP area, the project site is located in the Jurupa South Industrial District).
Regional access to the project site is available from Interstate 10 via Cherry Avenue and from State Route 60 via
Etiwanda Avenue. Additional regional access to the project site is available from Interstate 15 to the west and
Interstate 15 to the east. Local access roadways to the project include Etiwanda Avenue, Marlay Avenue and Industry
Avenue. The proposed project would be accessed via two full-access driveways on Industry Avenue. The north driveway
would be a 35-foot-wide passenger vehicle driveway along Industry Avenue providing fire access and access to the
parking lots and the south driveway would be a 40-foot-wide truck driveway providing access to the proposed vehicle
parking lot and truck court. Vehicle parking for employees would be located in a parking lot along the east and south
side of the project site. The site plan of the proposed project includes the detailed parking summary and is included
as Attachment B.
2 Trip Generation
2.1 Proposed Project Trip Generation
Table 1 provides a summary of trip generation estimates for the project based on ITE’s Trip Generation, 11th Edition,
for Warehousing use (ITE Code 150). Additionally, per the City’s direction on a similar project, the warehouse (non-
cold storage buildings) truck fleet mix from the South Coast Air Quality Management District’s (SCAQMD) Warehouse
Truck Trip Study Data Results and Usage (SCAQMD 2014a) was used to estimate project-related truck traffic. Based
on the SCAQMD data, passenger cars would account for 69% trips of the total trips generated by a warehouse
facility, and truck trips would account for approximately 31% of the total trips. The total percentage of truck trips
were further divided by 2-axle, 3-axle, and 4+ axle trucks per the SCAQMD study. These truck trips generated by the
project were then converted to PCE trips by using the recommended PCE factors. PCE factors consistent with the
City’s TIA guidelines were used to estimate the total PCE trips for the project.

and 3.0 for 4-axle trucks per City of Fontana TIA Guidelines (October 2020).
As shown in Table 1, the proposed project would generate approximately 212 daily trips, with 21 trips (16 inbound
and 5 outbound) in the AM peak hour, and 22 trips (6 inbound and 16 outbound) in the PM peak hour. Adjusting
for PCE, the trip generation is approximately 323 daily PCE trips, 32 AM PCE peak hour trips (25 inbound and 7
outbound) and 36 PM PCE peak hour trips (10 inbound and 26 outbound).
2.2 Existing Use Trip Generation
The project site is approximately 6.00 acres and contains light industrial use.
Table 2 summarizes the total daily and peak-hour trip generation for the existing site, using the passenger car and
truck splits for light industrial use from the Fontana Truck Trip Generation Study, August 2003. As shown on Table
2, the existing uses generate 530 daily trips, with 80 trips during the AM peak hour and 71 trips during the PM peak

2.3 Net New Project Trip Generation
The existing uses on the project site would be replaced by the proposed project; therefore, the trip generation was
estimated by subtracting the trips generated by the existing use from the proposed project trip generation. Because
the existing uses are currently operational, an existing use trip credit can be applied to estimate the project’s net
new trip generation (Table 3).

Net New Trips (PCE) -381 -71 -1 -72 -1 -57 -58
Notes: PCE = passenger car equivalent; Some of the totals may not match exactly due to rounding.
As shown in Table 3, the proposed project would generate approximately 318 fewer daily trips, with 59 fewer trips in the
AM peak hour, and 48 fewer trips in the PM peak hour. Adjusting for PCE, the trip generation is approximately 381 fewer
daily PCE trips, 72 fewer AM PCE peak hour trips and 58 fewer PM PCE peak hour trips.
3 LOS Screening Analysis
Per City’s TIA Guidelines (October 2020), the proposed project would not generate 50 or more AM or PM peak-hour
trips; therefore, it would not warrant a traffic analysis. Therefore, the proposed project would not require a
quantitative LOS analysis. Attachment B includes the City’s Traffic Scoping Form to support exemption from LOS
analysis and preparation of a TIA report.
4 VMT Screening Analysis
The Governor’s Office of Planning and Research prepared a comprehensive update to the CEQA Guidelines in 2017
that was approved by the California Natural Resources Agency in December 2018, requiring that lead agencies use
VMT for analyzing transportation impacts (OPR 2018). CEQA Guidelines Section 15064.3 states that “generally,
vehicle miles traveled (VMT) is the most appropriate measure of transportation impacts,” and define VMT as “the
amount and distance of automobile travel attributable to a project.” Note that “automobile” refers to on-road
passenger vehicles, specifically cars and light trucks. Heavy-duty truck VMT does not need to be included in the
Transportation Technical Memorandum

of Fontana
15031 6 JANUARY 2023
analysis, per Senate Bill 743 requirements. Other relevant considerations may include the effects of the project on
transit and non-motorized traveled.
Per City of Fontana’s TIA Guidelines (City of Fontana 2020), if a project generates fewer than 500 net daily trips
(non-PCE), it is deemed to not cause a substantial increase in the total citywide or regional VMT, and is therefore
presumed to have a less-than-significant impact on VMT. Substantial evidence in support of the 500 daily trip
threshold is documented in Appendix B, City of Fontana Senate Bill 743 Small Project Testing, of the City guidelines
(City of Fontana 2020). As noted in Table 3, the proposed project would generate 212 daily trips. By applying existing
use credit of 530 daily trips, the proposed project would result in 318 fewer non-PCE daily trips. Therefore, the
proposed project would not exceed the City’s 500 ADT screening threshold. Therefore, the project would result in a
less-than-significant impact for VMT; no further VMT analysis would be required.
5 Conclusions
Based on the trip generation analysis above and adjusting for PCE, the proposed project would generate fewer than
50 net new AM or PM peak-hour trips (see Table 3). Adjusting for PCE, and without using existing trip credit, the
project would generate approximately 32 new AM PCE peak-hour trips (25 inbound and 7 outbound) and 36 PM
PCE peak-hour trips (10 inbound and 26 outbound). Using existing trip credit, the project would generate 72 fewer AM
PCE peak hour trips and 58 fewer PM PCE peak hour trips. Per the City’s TIA guidelines and project trip generation
estimates, the proposed project would not be required to prepare an LOS analysis.
Based on the trip generation analysis above, the project would not generate 500 new daily trips. The proposed
project would be screened out from conducting further VMT analysis and is presumed to have a less-than-significant
VMT impact. Thus, the project would not require any mitigation.
