MEMORANDUM
To: Mahmoud Khodr
Senior Traffic Engineer
City of Fontana
From: Trevor Briggs, P.E.
Kimley-Horn and Associates, Inc.
Date: October 12, 2021
Subject: Trip Generation and VMT Screening Memorandum for the Proposed Citrus West
Residential Project in the City of Fontana
Kimley-Horn and Associates, Inc. has prepared a trip generation and vehicle miles traveled (VMT)
screening memorandum to evaluate the trip generation potential and VMT screening of the proposed
Citrus West Residential project.
PROJECT DESCRIPTION
The project site consists of approximately 9.4 acres of land located on the northwest corner of Citrus
Avenue and Summit Avenue in the City of Fontana. The project site is within the boundaries of the Citrus
Heights North Specific Plan. Based on the Citrus Heights North Specific Plan, the project site
is currently zoned as Neighborhood Commercial (PA 12). The Applicant proposes to amend the CHNSP Project site from Neighborhood Commercial to Residential-Medium Density. The
project site is currently vacant. The project applicant proposes to develop 86 multi-family dwelling units. A
copy of the project site plan is provided in Figure 1.
TRIP GENERATION COMPARISON
A trip generation analysis has been prepared to evaluate the consistency of the trip generating
characteristics for the proposed project, compared to the assumed land use in the Citrus Heights North
Specific Plan.
Potential Citrus Heights Specific Plan Trips – Project Site
The Citrus Heights North Specific Plan Draft Environmental Impact Report (DEIR) (dated: March
2004), provides trip generation estimates, based on the Institute of Transportation Engineers
(ITE) Trip Generation Manual (6th Edition) in Section 3.13 of the report.

The Specific Plan trip generation estimates assume the following proposed land use quantities:
·Single Family Residential (210) = 803 DUs
·Condominiums/Townhomes (230) = 425 DUs
·Shopping Center (820) = 107,000 square feet (SF)
Based on the proposed land use quantities, the Citrus Heights North Specific Plan would generate
approximately 14,939 daily trips, with 908 trips (250 inbound and 658 outbound) in the morning
peak hour, and 1,480 trips (888 inbound and 592 outbound) in the evening peak hour.
As noted earlier, the project site is currently zoned as Neighborhood Commercial. Therefore,
assuming 107,000 SF of shopping center use for the project site, the project site is estimated to
generate approximately 4,628 net new trips on a daily basis, with 108 net new trips during the
morning peak hour and 427 net new trips in the evening peak hour.
Trip generation estimates are shown on Table 1.
Trip Generation – Proposed Project
Trip generation estimates for the proposed project were based on the current ITE Trip Generation
Manual (10th Edition) trip rates for Multifamily Housing (Low-Rise) (ITE Code – 220).
Trip generation rates and the resulting trip generation estimates for the proposed project are
summarized on Table 1 (previously mentioned). Based on Table 1, the project is estimated to generate
630 daily trips, with 39 trips (9 inbound and 30 outbound) in the morning peak hour and 48 trips (30
inbound and 18 outbound) in the evening peak hour.
Compared to the Shopping Center land use in the Specific Plan DEIR, the proposed project would
generate 3,998 fewer trips on a daily basis, with 69 fewer trips in the morning peak hour, and 379
fewer trips in the evening peak hour.
Based on the trip generation comparison, the proposed project trip generation estimates are
materially less than the estimated trips for the proposed site in the Citrus Heights North Specific Plan
DEIR.

JURISDICTIONAL REQUIREMENTS
The City of Fontana Traffic Impact Analysis (TIA) Guidelines for Vehicle Miles Traveled (VMT) and Level
of Service Assessment (October 2020) provides guidance on when a Traffic Impact Study is required
for a project. The City document specifies that:
·If a project generates less than 50 peak hour trips, a traffic analysis shall not be required, and
a trip generation memo will be considered sufficient unless the City has specific concerns
related to project access and interaction with adjacent intersections.
Since the proposed project is expected to generate less than 50 peak hour trips, a traffic analysis is
not required.
CEQA VEHICLE MILES TRAVELED (VMT) ASSESSMENT
Senate Bill 743 (SB 743) was approved by California legislature in September 2013. SB 743 requires
changes to California Environmental Quality Act (CEQA), specifically directing the Governor’s Office of
Planning and Research (OPR) to develop alternative metrics to the use of vehicular “Level of Service”
(LOS) for evaluating transportation projects. OPR has prepared a technical advisory (“OPR Technical
Advisory”) for evaluating transportation impacts in CEQA and has recommended that Vehicle Miles
Traveled (VMT) replace LOS as the primary measure of transportation impacts. The Natural
Resources Agency has adopted updates to CEQA Guidelines to incorporate SB 743 that requires VMT
for the purposes of determining a significant transportation impact under CEQA.
The City of Fontana’s Traffic Impact Analysis (TIA) Guidelines for Vehicle Miles Traveled (VMT) and
Level of Service Assessment (October 2020) provides details 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 level analysis. Screening thresholds are broken
down into the following four steps:
1. Projects in a Transit Priority Area (TPA)
2. Low VMT Area
3. Low Project Type
4. Project Net Daily Trip Less Than 500 ADT

Mr.Khodr,October 12, 2021,Page 6
Land development projects that meet one or more of the above screening thresholds may be
presumed to create a less than significant impact on transportation and circulation.
Projects in a Transit Priority Area (TPA)
In accordance the City of Fontana’s Traffic Impact Analysis (TIA) Guidelines for Vehicle Miles Traveled
(VMT) and Level of Service Assessment (October 2020), projects located within half mile from an
existing major transit stop or within half of a mile from an existing stop along a high-quality transit
corridor can be screened out. Based on San Bernardino County Transportation Authority (SBCTA)
VMT Screening Tool, the project is not located in a Transit Priority Area (TPA). The TPA screening
criteria is not met.
Low VMT Area
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. Based on the traffic analysis
zone (“TAZ”) that the project is in and the San Bernardino County Traffic Analysis Model (SBTAM)
travel forecast model, the low VMT area screening criteria is not met.
Low Project Type
The City presumes various usages, assumed to be local serving in nature, as having less than
significant impact absent of substantial evidence to the contrary. The low VMT project type
screening is not met for this project.
Project Net Daily Trips Less Than 500 ADT:
The City presumes that projects that generate fewer than 500 average daily trips (ADT) would not
cause a substantial increase in the total citywide or regional VMT and would therefore have a less
than significant impact on VMT. Based on the trip generation noted earlier, the project is expected
to generate more than 500 average net new daily trips. Therefore, the less than 500 ADT screening
criteria is not met for the project.

VMT Analysis
In March 2004, UltraSystems Environmental analyzed trip generations and traffic impacts
associated with the Citrus Heights North Specific Plan DEIR. As noted previously in this traffic
memorandum, compared to the current zoning (Neighborhood Commercial) for the project site,
the proposed project would generate 3,998 fewer trips on a daily basis, with 69 fewer trips in the
morning peak hour, and 379 fewer trips in the evening peak hour.
The proposed project would generate significantly less trips than the land use assumptions noted
in the Citrus Heights North Specific Plan DEIR for the project site. The proposed project would not
change the Specific Plan DEIR determination regarding impacts associated with increased traffic
volumes. Therefore, the proposed project would create a less-than-significant VMT impact, and no
further analysis is required.
FINDINGS AND CONCLUSIONS
Based on review of the City’s guidelines, the project is expected to generate less than 50 peak hour
trips; therefore, a Level of Service analysis is not required. Based on the VMT assessment noted in
this traffic memorandum, the proposed project would create a less-than-significant VMT impact,
compared to the assumed land uses for the project site in the Citrus Heights North Specific Plan;
therefore, no further analysis is required
