Subject: Trip Generation and Vehicle Miles Traveled (VMT) Screening Analysis (EPD 21-130)-
Application Case Number: MCN22-105
This technical memorandum evaluates the need to prepare a level of service (LOS), or vehicle miles traveled
(VMT) analysis for the proposed industrial project located at 16025 Slover Avenue. This memo also provides,
as an attachment, a comparison of the trip generation of the proposed project with site land use that was
analyzed as part of the Southwest Industrial Park (SWIP) Traffic Analysis1. The purpose of the comparison
is to determine if the project as proposed would have any greater impact than the previously analyzed
SWIP land use. This comparison is required to support the conclusions of the project’s evaluation under the
California Environmental Quality Act (CEQA). The proposed project would replace McKinney Trailer Rental,
four specialty trade contractors, and two single family houses with a 385,970 SF high-cube warehouse at
the southwest corner of Citrus Avenue and Slover Avenue in the City of Fontana. The project site plan is shown
in Figure 1. This memo will evaluate the project using the City of Fontana Traffic Impact Analysis (TIA)
Guidelines (October 21, 2020).
Project Trip Generation Comparison with Existing Site Uses
A trip generation analysis comparing the proposed project’s trip generation to the existing site uses was also
prepared. Existing trips generated by the land uses currently on-site were reduced from the project trip
generation. The trip rates for McKinney Trailer Rentals were taken from a trip generation survey taken at
the McKinney Trailer Rental Facility Located at 10641 Calabash Avenue, Fontana, on Wednesday August
7, 2019. The existing land uses include small businesses that include automobile storage, engineering
supplies, sign suppliers, a construction contractor and pool service. To estimate the trips generated by these
uses, the rate for Specialty Trade Contractor (Land Use Code 180) from the Institute of Transportation
Engineers (ITE) was used. Specialty Trade Contractor is defined by ITE as a business primarily involved in
providing contract repairs and services to meet industrial or residential needs and includes business that
provide services such as home repairs, industrial supplies, locksmith services and cleaning. To estimate two
single family houses project trip generation, Single Family Detached Housing (Land Use Code 210) trip rates
from the Institute of Transportation Engineers (ITE) were used. The reduction in the number of trips generated
by the proposed Project occurred because the number of trips generated by Single Family use is less than
the previous use, which was Specialty Trade Contractors. Traffic counts are provided in Attachment A. As
shown in Table 1, the project would generate 24 new PCE trips during the AM peak hour and 31 new PCE
trips during the PM peak hour. As shown in Tables 1, the Project, while anticipated to generate more daily,
AM, and PM peak hour PCE trips than the existing use, is anticipated to generate fewer than 50 new peak
hour trips, as indicated in Table 1. Therefore, per the City’s TIA guidelines, the project would not be required
to prepare a LOS traffic analysis.

VMT Screening Analysis
Senate Bill (SB) 743 was signed by Governor Brown in 2013 and required the Governor’s Office of Planning and Research (OPR) to amend the CEQA Guidelines to provide an alternative to LOS for evaluating Transportation impacts. SB743 specified that the new criteria should promote the reduction of greenhouse gas emissions, the development of multimodal transportation networks and a diversity of land uses. The bill also specified that delay-based level of service could no longer be considered an indicator of a significant
impact on the environment. In response, Section 15064.3 was added to the CEQA Guidelines beginning
January 1, 2019. Section 15064.3 - Determining the Significance of Transportation Impacts states that
Vehicle Miles Traveled (VMT) is the most appropriate measure of transportation impacts and provides lead
agencies with the discretion to choose the most appropriate methodology and thresholds for evaluating VMT.
City of Fontana VMT Screening
Section 12.2 of the City’s Traffic Impact Analysis Guidelines provides VMT screening thresholds to identify
projects that would be considered to have a less-than significant impact on VMT and therefore could be
screened out from further analysis. If a project meets one of the following criteria, then the VMT impact of
the project would be considered less-than significant and no further analysis of VMT would be required:
1. The project is located within a Transit Priority Area (TPA).
2. The project is located in a low VMT generating area.
3. The project is considered a local-serving land use.
4. The project net daily trips are less than 500 ADT.
The applicability of each criterion to the project is discussed below.
Screening Criteria 1 - Transit Priority Area (TPA) Screening: According to the City’s guidelines, projects
located in a TPA may be presumed to have a less than significant impact. The project is not located in a TPA;
therefore the project would not satisfy the requirements of Screening Criteria 1 – TPA screening.
Screening Criteria 2 - Low VMT Area Screening: The City’s guidelines include a screening threshold for
projects located in a low VMT generating area. Low VMT generating area is defined as traffic analysis
zones (TAZs) with a total daily VMT/Service Population (employment plus population) that is 15% less than
the baseline level for the County. The project’s site was evaluated using the SBCTA VMT Screening Tool
(SBCTA VMT Screening Tool (arcgis.com)). As shown in Figure 2, the Countywide VMT/Service Population is
33.3 and the VMT/Service Population for the project zone is 47.04. The VMT/Service Population of the
project zone is above the County average. Therefore, the project would not meet Screening Criteria 2 –
Low-VMT Area Screening.
Screening Criteria 3 – Low Project Type: According to the City’s guidelines, projects which propose local
serving retail (retail projects less than 50,000 SF) or other local serving uses would have a less than significant
impact on VMT. The types of projects considered local serving include supermarkets, hair/nail salon, walk-in
medical clinics/urgent care, K-12 schools, day care centers, and community institutions such as libraries, fire
stations, etc. The project does not propose a local serving land use and therefore would not satisfy the
requirements of screening criteria 3.
Screening Criteria 4 – Net Daily Trips less than 500 ADT: According to the City’s guidelines, projects which
would generate fewer than 500 average daily trips (ADT) would not cause a substantial increase in the total
citywide or regional VMT. As shown in Table 1, the project would generate an increase of 309 daily trips
when compared to the existing land uses. Because the project would generate an increase of less than 500
ADT when compared to the existing land use, it is presumed to have a less than significant impact on VMT and further analysis would not be required.
Project Site Access
Regional access to the Project site is provided by Interstate 10 (I-10) from Citrus Avenue exits, or from State
Route 60 (SR-60) from the Country Village Road exit, and Interstate 15 (I-15) off the E Jurupa Avenue exit.

Local Access to the Project site is provided via two truck driveways (one on Catawba Avenue and one on
Slover Avenue) and three automobile driveways (one on Catawba Avenue and two on Citrus Avenue). Trucks are expected to enter and exit the site primarily from Slover Avenue. Truck trip distributions and trip assignments are shown on Figures 3 and 4 respectively. Automobile trip distributions are shown in Figure 5.
Summary
As shown in Table 1, the Project, while anticipated to generate more daily, AM, and PM peak hour PCE trips than the existing use, is anticipated to generate fewer than 50 new peak hour trips. Therefore, per the City’s TIA guidelines, the project would not be required to prepare a LOS traffic analysis. The project was evaluated using the City of Fontana VMT screening thresholds to determine if the project would require a vehicle mile traveled (VMT) analysis. The project would generate an increase of less than 500 ADT when compared to the previously analyzed and approved land use. Therefore, the project VMT impacts would be
considered less than significant and further analysis of VMT would not be required.

Attachment B – Project Trip Generation Comparison with the SWIP Specific Plan
The Maximum FAR in the SWIP for industrial uses is 0.55; therefore, the 748,346 SF site under the SWIP was analyzed at
411,590 SF of warehouse as follows: 748,346 𝑓𝑓𝑓𝑓2 ∗0.55 =411,590 𝑓𝑓𝑓𝑓2
The SWIP was analyzed in the previous traffic analysis using trip rates from the Institute of Transportation Engineers (ITE) Trip
Generation Manual 8th Edition. To make an appropriate comparison, Table 2: Approved SWIP Trip Generation shows the site
analyzed as a 411,590 SF warehouse using the previous ITE 8th edition trip rates and the current ITE 11th edition trip rates, and
Table 3: Proposed Project Trip Generation shows the proposed 385,970 SF warehouse using the previous ITE 8th edition and the
current ITE 11th edition trip rates. It should be noted that the project is more than 200,000 SF and therefore the rates for High-Cube
Transload and Short-Term Storage Warehouse would apply. However, rates for High Cube Transload and Short-Term Storage
Warehouse were not used in the SWIP traffic analysis, therefore, to provide a comparative analysis, the trip generation evaluation
will evaluate the project as “Warehouse”, consistent with the SWIP traffic analysis.
Table 4 provides a comparison of the project trip generation to the previously analyzed project. As shown in Table 4, the proposed
project would generate fewer trips on this site than the previously approved SWIP using both the 8th and 11th edition Warehouse
rates, therefore no new impacts would occur that were not disclosed in the previous analysis. It should be noted that the project will
pay all applicable traffic impact fees, which would be used to fund the local and regional transportation system. These fees are
intended to mitigate the cumulative traffic effects of land development projects.
