SUBJECT: SCOPING AGREEMENT FOR THE SIERRA INDUSTRIAL FACILITY (SHEA) TRAFFIC ASSESSMENT
Dear Mr. Mahmoud Khodr:
The firm of Urban Crossroads, Inc. is pleased to submit this letter documenting the recommended
Scope of Work for the traffic assessment in support of the proposed Sierra Industrial Facility (Shea)
development (Project), which is located north of Casa Grande Drive and east of Sierra Avenue in the
City of Fontana. Exhibit 1 depicts the location of the proposed Project in relation to the existing
roadway network.
Our goal is to obtain comments from City of Fontana staff, to ensure that the traffic assessment fully
addresses the potential effects of the proposed Project. The remainder of this letter describes the
draft proposed analysis methodology, project trip generation, and trip distribution for the Project.

The Project is to consist of a 203,000 square foot warehouse building (this includes a 3,000 square foot
mezzanine). A preliminary site plan for the proposed Project is shown on Exhibit 2. As indicated on
Exhibit 2, access to the Project site will be provided to Sierra Avenue. The northerly driveway
(Driveway 1) is proposed to have right-in/right-out access only with full access assumed at the
southerly driveway (Driveway 2).

PROJECT TRIP GENERATION
The Project consists of the development of a 203,000 square foot warehouse building (see Exhibit 2).
Trip generation represents the amount of traffic that is attracted and produced by a development and
is based upon the specific land uses planned for a given project. In order to develop the traffic
characteristics of the proposed project, trip-generation statistics published in the Institute of
Transportation Engineers (ITE) Trip Generation Manual (11
th Edition, 2021) was used to estimate the
trip generation. Trip generation rates for the Project are shown in Table 1.

Passenger car equivalent (PCE) factors were applied to the trip generation rates for heavy trucks (large
2-axles, 3-axles, 4+-axles). PCEs allow the typical “real-world” mix of vehicle types to be represented as
a single, standardized unit, such as the passenger car, to be used for the purposes of capacity and level
of service analyses. The PCE factors are consistent with the recommended PCE factors in the City’s
Traffic Impact Analysis Guidelines for VMT and LOS Assessment (October 2020, referred to as City’s
Guidelines).
For purposes of this scoping agreement, the following ITE land use codes and vehicle mixes will be
utilized for the proposed Project:
High-Cube Fulfillment Center Warehouse (ITE Land Use Code 155) has been used to derive site
specific trip generation estimates for up to 182,700 square feet of the proposed Project (or 90%
of the overall building square footage). The ITE Trip Generation Manual has trip generation
rates for high-cube fulfillment center use for both non-sort and sort facilities (ITE land use code
155). As defined by ITE, a high-cube warehouse is a building that typically has at least 200,000
gross square feet of floor area, has a ceiling height of 24 feet or more, and is used primarily for
the storage and/or consolidation of manufactured goods (and to a lesser extent, raw materials)
prior to their distribution to retail locations or other warehouses. A typical high-cube warehouse
has a high level of on-site automation and logistics management. The automation and logistics
enable highly-efficient processing of goods through the high-cube warehouse.The ITE Trip
Generation Manual has two subcategories for the High-Cube Fulfillment Center use: sort and
non-sort. ITE describes a sort facility as a fulfillment center that ships out smaller items,
requiring extensive sorting, typically by manual means. In comparison, a non-sort facility is a
fulfillment center that ships large box items that are processed primarily with automation rather
than through manual means. Some limited assembly and repackaging may occur within the
facility. Given this description, a non-sort facility has been assumed for the purposes of
calculating trip generation for the Project. The vehicle mix (passenger cars versus trucks) has
been obtained from the ITE’s Trip Generation Manual. The truck percentages were further
broken down by axle type per the following SCAQMD recommended truck mix: 2-Axle = 16.7%;
3-Axle = 20.7%; 4+-Axle = 62.6%.
High-Cube Cold Storage Warehouse (ITE Land Use Code 157) has been used to derive site
specific trip generation estimates for up to 20,300 square feet (10% of the overall building
square footage). High-cube cold storage warehouses include warehouses characterized by the
storage and/or consolidation of manufactured goods (and to a lesser extent, raw materials)
prior to their distribution to retail locations or other warehouses. High-cube cold storage
warehouses are facilities typified by temperature-controlled environments for frozen food or
other perishable products. The High-Cube Cold Storage Warehouse vehicle mix has been
obtained from the ITE’s Trip Generation Manual. The truck percentages were further broken
down by axle type per the following SCAQMD recommended truck mix: 2-Axle = 34.7%; 3-Axle =
11.0%; 4+-Axle = 54.3%.

TABLE 3: PROJECT TRIP GENERATION SUMMARY (PCE)
According to the City’s Guidelines:
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.
TRIP GENERATION COMPARISON
The Project is proposing a General Plan Amendment and Zone Change to revise the General Plan Land
use from Multi-Family High Density Residential to Light Industrial and the zoning from Multi-Family
High Density (R-5) to Light Industrial (M-1). The R-5 zoning designation allows up to a maximum of 50
dwelling units per acre. Based on the Project’s acreage of 11.26 acres, approximately 563 high density
dwelling units could be developed on site. A trip generation comparison is shown on Table 4 to
demonstrate the net change in trip generation is an overall reduction from the currently adopted land
use/zoning.

TRIP DISTRIBUTION
Trip distribution is the process of identifying the probable destinations, directions, or traffic routes that
will be utilized by Project traffic. The potential interaction between the planned land uses and
surrounding regional access routes are considered, to identify the route where the Project traffic
would distribute. Exhibits 4 and 5 illustrate the passenger car and truck trip distribution patterns
through the study area intersections, respectively.

STUDY AREA
Based on the Project’s anticipated trip generation, the Project would generate fewer than 50 peak
hour trips and would contribute fewer than 50 peak hour trips to any study area intersection. As such,
no further operations analysis has been proposed for this Project beyond the trip generation
assessment discussed above.
SPECIAL ISSUES
A Vehicle Miles Traveled (VMT) analysis will be addressed under separate cover. In addition, a
separate SB330 evaluation will be prepared for the site(s) anticipated to accommodate the transfer of
563 dwelling units from the proposed Project site.
