ALDER & MERRILL TRIP GENERATION ASSESSMENT
Urban Crossroads, Inc. is pleased to provide the following Trip Generation
Assessment for the proposed Alder & Merrill change of zone (Project), which is
located in the City of Fontana. It should be noted that this trip generation
assessment has been prepared in accordance with the City of Fontana Traffic
Impact Analysis (TIA) Guidelines for Vehicle Miles Traveled (VMT) and Level of
Service (LOS) Assessment (dated October 21, 2020) (City Guidelines).
PROJECT DESCRPTION
The Project consists of a proposed General Plan Amendment (GPA) and a Zone
Change (ZC) for a 6.4-acre property that is located in the City of Fontana north of
Merrill Avenue, between Alder Avenue and Laurel Avenue, and south of Citron
Avenue. The GPA would change the General Plan land use designation of the
Project site from Single Family Residential (R-SF) to Multifamily Medium High-
Density Residential (R-MFMH) and the zoning of the Project site from Single Family
Residential (R-1) to Multifamily Medium/High Density Residential (R-4). The existing
General Plan land use and zoning are shown on Exhibit 1 and the proposed GPA
and ZC are shown on Exhibit 2. The increased unit count allowance would increase
from a maximum of 32 residential units (6.4 acres x 5.0 units/acre = 32 units) to
249 residential units (6.4 acres x 39 units/acre = 249 units), for a net increase of
217 units assuming maximum development potential under the existing and
proposed designations. No development project is currently proposed, and no
physical disturbance of the Project site is currently proposed. Only the proposed
change to the underlying land use has been evaluated as part of this assessment.

TRIP GENERATION
EXISTING GENERAL PLAN LAND USE/ZONING
The existing General Plan land use designation of the Project site is R-SF and the zoning is R-1
which allows for a maximum development 32 residential units (6.4 acres x 5.0 units/acre = 32
units). In order to develop the traffic characteristics for the existing use, trip-generation statistics
published in the Institute of Transportation Engineers (ITE) Trip Generation Manual (11th Edition,
2021) for Single Family Detached Housing (ITE Land Use Code 210) was used for the existing
General Plan land use. Table 1 presents the trip generation rates and the resulting trip
generation, which shows the existing General Plan use currently generates a total of 302 two-way
trips per day with 23 AM peak hour trips and 30 PM peak hour trips.

TABLE 1: TRIP GENERATION FOR EXISTING GENERAL PLAN LAND USE
PROPOSED GENERAL PLAN LAND USE/ZONING
The GPA would change the General Plan land use designation of the Project site to R-MFMH and
the zoning of the Project site R-4, which allows for a maximum of 249 residential units (6.4 acres
x 39 units/acre = 249 units). The net increase is 217 units assuming maximum development
potential under the existing (32 units) and proposed (249 units) designations.
Trip-generation statistics published in the ITE Trip Generation Manual (11th Edition, 2021) for
Multifamily Housing (Mid-Rise) (ITE Land Use Code 221) was used for the proposed General Plan
land use. Table 2 presents the trip generation rates and the resulting trip generation, which
shows the proposed General Plan land use is anticipated to generate a total of 1,130 two-way
trips per day with 23 AM peak hour trips and 30 PM peak hour trips.

TRIP GENERATION COMPARISON
Table 3 shows the trip generation comparison between the existing and proposed General Plan
Land Use/Zoning. The resulting net new trips are identified on Table 3. As shown, the proposed
Project is anticipated to generate 828 net new two-way trips per day with 69 net new AM peak
hour trips and 67 net new PM peak hour trips as compared to the existing General Plan Land
Use/Zoning.
