BACKGROUND
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) (1). Based on OPR’s Technical
Advisory, specific procedures for complying with the new CEQA requirements for VMT analysis,
the City of Fontana adopted Traffic Impact Analysis Guidelines for Vehicle Miles Traveled and
Level of Service Assessment (City Guidelines) (2). The City Guidelines documents the City’s VMT
analysis methodology and adopted VMT impact thresholds. The VMT screening evaluation
presented in this report has been developed based on these City Guidelines.
VMT SCREENING
The City Guidelines describe specific “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 VMT analysis. For the purposes of this analysis, the initial
VMT screening process has been conducted with the SBCTA VMT Screening Tool (Screening
Tool), which uses screening criteria consistent with the screening thresholds recommended in
the City Guidelines. Screening thresholds are described in the following four steps:
• Step 1: Transit Priority Area (TPA) Screening
• Step 2: Low VMT Area Screening
• Step 3: Low (Local Serving) Project Type Screening
• Step 4: Project net daily trips less than 500 ADT
Consistent with City Guidelines, a land use project needs only to satisfy one of the above
screening thresholds to result in a less than significant impact.
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
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.”).

substantial evidence to the contrary. However, the presumption may not be appropriate if a
project:
• 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 Attachment A, 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.
STEP 2: LOW VMT AREA SCREENING
As noted 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”3. The Screening Tool uses the sub-regional San Bernardino County Transportation
Analysis Model (SBTAM) to measure VMT performance within San Bernardino County for
individual traffic analysis zones (TAZ’s) within each city.
The Project’s physical location is selected by the Screening Tool to determine the VMT generated
within the respective TAZ as compared to the jurisdictional average inclusive of a particular
threshold (i.e., 15% below baseline County of San Bernardino VMT per service population (SP) or
28.3 VMT per SP). Based on the Screening Tool results, the Project is located in TAZ 53719401 and
the Project’s TAZ has a VMT per SP of 28.3. Therefore, the Project is not located in a low VMT area
and does not have a VMT per SP below the City’s adopted threshold of 15% below baseline County
of San Bernardino VMT per service population (See Attachment A).
Low VMT Area screening criteria is not met.
STEP 3: LOW (LOCAL SERVING) PROJECT TYPE SCREENING
The City Guidelines identify that local serving retail with buildings less than 50,000 square feet or
other local serving essential services (e.g., day care centers, public schools, medical/dental office
buildings, etc.) are presumed to have a less than significant impact absent substantial evidence
to the contrary. The proposed Project is not considered a local serving use based on the examples

provided in the City Guidelines.4 The Project does not intend to develop local serving retail or
local serving essential services land use types.
Low (Local Serving) Project Type screening criteria is not met.
STEP 4: PROJECT NET DAILY TRIPS LESS THAN 500 ADT SCREENING
Projects that generate fewer than 500 net average daily trips (ADT) (stated in actual vehicles) are
deemed to 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. Substantial evidence in support of the
daily trip threshold is documented in the City Guidelines.5 The trip generation rates used for the
proposed Project are based on the trip generation statistics published in the Institute of
Transportation Engineers (ITE) Trip Generation Manual (11th Edition, 2021) (3).
The 39.2-acre Project site is located in the original Southridge Village Specific Plan (SVSP). The
1982 SVSP EIR (Original Specific Plan) analyzed the development of 8,800 residential units within
the entire SVSP area.
TABLE 1: SVSP CAPACITIES AT BUILDOUT
Dwelling Units
Original Specific Plan 8,800
Proposed Project 7,999
The Proposed Project intends to develop 255 units on the 39.2-acre site (Planning Areas 66A, 66B,
and 56). The Proposed Project is within the remaining development capacity of SVSP. Of the 255
units, 92 units were assumed to occur on the site and 163 would be transferred from the overall
remaining capacity, which is permitted by the SVSP. Therefore, buildout of the SVSP as modified
by the Project is assumed to be 7,999 units.
Table 2 presents a trip generation comparison between the original SVSP and the Currently
Proposed Project.

TABLE 2: TRIP GENERATION COMPARISON
The Currently Proposed Project is estimated to generate a net reduction of 8,122 daily vehicle
trips as compared to the Original Specific Plan, which would not exceed the City’s screening
threshold of 500 daily vehicle trips.
Project net daily trips less than 500 ADT screening criteria is met.
CONCLUSION
In summary, the Project was evaluated consistent with the City’s available screening criteria. The
Project was found to meet the Project Net Daily Trips Less than 500 ADT screening criteria and is
presumed to result in a less than significant impact for VMT; no further VMT analysis required.
