Subject: Traffic Impact and VMT Assessment for the Proposed
Homelessness Prevention Resource and Care Center Project
Fontana, California
Dear Mr. Perrine:
Linscott, Law & Greenspan, Engineers (LLG) is pleased to submit this Traffic Impact
and VMT Assessment for the proposed Homelessness Prevention Resource and
Care Center Project (herein referred to as “Project”), located on the southwest
quadrant of Arrow Boulevard and Tokay Avenue in the City of Fontana, California.
The proposed Project encompasses two (2) separate potential development areas
(Project Site A and Project Site B), both of which are currently vacant. Figure 1
presents a Vicinity Map, which illustrates the general location of the two project
sites and depicts the surrounding street system and Figure 2 presents an existing
site aerial.
This letter report will outline the traffic generation forecast potential for the proposed
Project Site A (no development proposed for Project Site B) and assess whether
the proposed Project will create any potential traffic impacts on the surrounding
transportation system based on the City of Fontana Traffic Impact Analysis (TIA)
Guidelines for Vehicle Miles Traveled (VMT) and Level of Service Assessment,
dated October 21, 2020. In addition for CEQA purposes, the letter report will
evaluate Vehicle Miles Traveled (VMT) screening options per the City’s
guidelines for both Project Site A and Project Site B.
Our method of analysis, findings, and recommendations are detailed in the
following sections of this letter report.

PROJECT DESCRIPTION
The proposed Project will encompass two (2) separate potential development areas
(Project Site A: APN’s 0232-171-05, 06, 07, & 08 and Project Site B: APN’s 0232-
171-09, 12, 13, & 14) and will include a land redesignation from Open Space to
Industrial for both sites. Project Site A will consist of construction and operation of a
homelessness prevention resources and care center on approximately seven (7) acres,
which will include of a maximum of 150 modular dwelling units, a 6,000 square-foot
(SF) administration building, and support site amenities, whereas Project Site B will
only consist of the land use redesignation to Industrial without any planned
development as part of this Application. Access for Project Site A will be provided
via one (1) full access unsignalized driveway located along Arrow Boulevard and via
one (1) right-in/right-out unsignalized driveway located along Tokay Avenue.
Figure 3 presents the proposed site plan for Project Site A, prepared by the City of
Fontana.
PROJECT TRAFFIC GENERATION FORECAST
Traffic generation is expressed in vehicle trip ends, defined as one-way vehicular
movements, either entering or exiting the generating land use. Generation equations
and/or rates used in the traffic forecasting procedure are found in the 11th Edition of
Trip Generation, published by the Institute of Transportation Engineers (ITE)
[Washington D.C., 2021].
Table 1, located at the rear of this letter report following the figures, summarizes the
trip generation rates used in forecasting the vehicular trips generated by the proposed
Project and presents the forecast daily and peak hour project traffic volumes for a
“typical” weekday. As shown in the upper portion of Table 1, given that the ITE Trip
Generation Manual does not include a specific land use category for homeless
prevention related facilities, the trip generation potential of the proposed Project Site
A has been estimated using ITE Land Use 254: Assisted Living trip rates. It should be
noted that the ITE definition for Assisted Living is very similar to the Proposed
Project as it consists of “a residential setting that provides either routine general
protective oversight or assistance with activities necessary for independent living to
persons with mental or physical limitations… The complex commonly provides
separate living quarters for each resident… Staff may be available 24 hours a day, but
skilled medical care is not required.”
A review of the lower portion of Table 1 indicates that the proposed Project Site A is
forecast to generate approximately 390 daily trips, with 27 trips (16 inbound, 11

outbound) produced in the AM peak hour and 36 trips (14 inbound, 22 outbound)
produced in the PM peak hour on a “typical” weekday.
TRAFFIC IMPACT ASSESSMENT
According to the City of Fontana Traffic Impact Analysis (TIA) Guidelines for Vehicle
Miles Traveled (VMT) and Level of Service Assessment, dated October 21 2020, the
following criteria should be utilized to determine if a traffic impact study is required
for a project.
A TIA must be prepared when a proposed change in land use, development
project, or at local discretion, a group of projects are forecast to equal or exceed the
CMP threshold of 250 two‐way peak hour trips generated, based on trip generation
rates published for the applicable use or uses in the Institute of Transportation
Engineers Trip Generation Manual or other approved data source. Pass‐by
trips shall not be considered in the threshold determination. However, industrial,
warehousing and truck projects shall convert trucks to PCE’s before applying the
above threshold.
If a project is forecast to generate between 100 and 249 two‐way peak hour
trips, a traffic impact analysis will be required, but the extent of the analysis will
be lesser.
If a project generates between 50 and 100 two‐way peak hour trips, a focused
traffic analysis will be required.
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.
Based on the aforementioned City of Fontana criteria, the trips associated with the
proposed Project Site A are below the 50 peak hour trip threshold requiring the
preparation of a traffic impact analysis report. Therefore, we conclude that the
proposed Project will not require the preparation of a traffic impact analysis report.
VEHICLE MILES TRAVELED (VMT) ASSESSMENT
On December 28, 2018, the California Natural Resources Agency adopted revised
CEQA Guidelines. Among the changes to the guidelines was the removal of vehicle
delay and LOS from consideration for transportation impacts under CEQA. With the
Mr. Brad Perrine April 26, 2023
Page 4
adopted guidelines, transportation impacts are to be evaluated based on a project’s
effect on vehicle miles traveled. Lead agencies are allowed to continue using their
current impact criteria, or to opt into the revised transportation guidelines. However,
the new guidelines must be used starting July 1, 2020, as required in CEQA section
15064.3. The City of Fontana recently adopted new transportation impact criteria in
June 2020 to be consistent with the CEQA revisions. These new guidelines are
contained within the City of Fontana Traffic Impact Analysis (TIA) Guidelines for
Vehicle Miles Traveled (VMT) and Level of Service Assessment, dated June 2020 and
provide screening criteria and methodology for VMT analysis.
Per the City of Fontana Traffic Impact Analysis (TIA) Guidelines for Vehicle Miles
Traveled (VMT) and Level of Service Assessment, there are three types of screening to
screen projects from project-level VMT assessments. The three screening steps are
described below. The results of each screening step applied to the proposed Project is
also discussed. It should be noted that the project only needs to satisfy one of the
three screening steps.
Step 1: Transit Priority Area (TPA) Screening
Projects located within a transit priority area (TPA) may be presumed to have a less than significant impact absent substantial evidence to the contrary. This presumption
may NOT be appropriate if the project: 1. Has a Floor Area Ratio (FAR) of less than 0.75;
2. Includes more parking for use by residents, customers, or employees of the
project than required by the City requirements;
3. Is inconsistent with the applicable Sustainable Communities Strategy (as
determined by the lead agency, with input from the Metropolitan Planning
Organization); or
4. Replaces affordable residential units with a smaller number of moderate- or
high-income residential units.
Based on the SBCTA screening tool, Project Site A and Project Site B are both
not located within a Transit Priority Area (TPA). As a result, Project Screening
Step 1: Transit Priority Area (TPA) Screening criteria is not satisfied.
Step 2: Low VMT Area Screening 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. A low VMT area is defined as an

individual traffic analysis zone (TAZ) where total daily Origin/Destination VMT per service population is fifteen percent (15%) lower than the County average total
daily Origin/Destination VMT per service population.
Based on the SBCTA screening tool, Project Site A and Project Site B are both
located within Traffic Analysis Zone (TAZ) #53723201. Per the SBCTA screening tool, the Project TAZ VMT/service population is 25.7 VMT per service population and the County average VMT/service population is 32.7 VMT per service
population. Comparison of the two VMT values indicates that the Project TAZ
VMT is 21.41% lower than the County VMT average. Therefore, Project
Screening Step 2: Low VMT Area Screening is satisfied.

Step 3: Low Project Type Screening
Local serving retail projects less than 50,000 square feet may be presumed to have a less than significant impact absent substantial evidence to the contrary. Local serving retail generally improves the convenience of shopping close to home and has the effect of reducing vehicle travel. In addition to local serving retail, the following uses can also be presumed to have a less than significant impact absent substantial
evidence to the contrary as their uses are local serving in nature:
Local-serving K-12 schools
Local parks
Day care centers
Local-serving gas stations
Local-serving banks
Local-serving hotels (e.g. non-destination hotels)
Student housing projects on or adjacent to college campuses
Local-serving assembly uses (places of worship, community organizations)
Community institutions (Public libraries, fire stations, local government)
Local serving community colleges that are consistent with the assumptions noted in the RTP/SCS
Affordable or supportive housing
Assisted living facilities
Senior housing (as defined by HUD)

Based on the Project description, Project Site A is considered supportive housing and assisted living facility based on the “Low Project Type Screening” criteria.
As a result, Project Screening Step 3: Low Project Type Screening criteria is
satisfied.
Step 4: Project net daily trips less than 500 ADT
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 presumed
to have a less than significant impact on VMT. Local serving retail generally
improves the convenience of shopping close to home and has the effect of reducing vehicle travel. In addition to local serving retail, the following uses
As stated previously, the proposed Project Site A will consist of a maximum of
150 modular dwelling units for homelessness prevention and is forecast to
generate 390 daily trips. Therefore, based on the aforementioned criteria,
Project Screening Step 4: Project net daily trips less than 500 ADT is satisfied.
Based on the City’s guidelines, the proposed Project Site A satisfies Step 2: Low
VMT Area Screening, Step 3: Low Project Type Screening, and Step 4: Project net
daily trips less than 500 ADT, while Project Site B satisfies Step 2: Low VMT Area
Screening. Therefore, both Project Site A and Project Site B could be screened from a
full VMT analysis, and could be presumed to have a less than significant impact on
VMT per the City of Fontana Traffic Impact Analysis (TIA) Guidelines for Vehicle
Miles Traveled (VMT) and Level of Service Assessment.
CONCLUSION
Based on the aforementioned City of Fontana criteria, the peak hour trips associated
with the proposed Project (i.e. 27 AM peak hour trips and 36 PM peak hour trips) is
below the City’s “50-trip” threshold requiring the preparation of a Traffic Impact
Analysis Report. Additionally, the proposed Project Site A satisfies Project
Screening – “Step 2: Low VMT Area Screening”, “Step 3: Low Project Type
Screening”, and “Step 4: Project net daily trips less than 500 ADT”, while Project
Site B satisfies “Step 2: Low VMT Area Screening” and could be screened from a full
VMT analysis. Therefore, we conclude that the proposed Project Site A will not
require the preparation of a Traffic Impact Analysis report, while both Project Site A
and Project Site B will not require a full VMT analysis report.
