Subject: Biological Resources Technical Report for the 11700 Industry Avenue Warehouse Project, City of
Fontana, San Bernardino County, California
Dear Lonnie Nadal:
The biological resources technical memorandum documents the existing biological conditions for the approximately
6.00-acre property located at Assessor’s Parcel Number (APN) 0238-171-37, in Fontana, San Bernardino County,
California. This report evaluates the potential for special-status biological resources to occur on the project site
based on the existing conditions observed during a biological reconnaissance and includes a discussion of potential
impacts to biological resources due to implementation of the 11700 Industry Avenue Warehouse Project (project).
This report also provides recommendations to avoid or minimize impacts to below a level of significance under the
California Environmental Quality Act (CEQA).
1 Project Location
The project site is generally located west of Industry Avenue and east of S. Etiwanda Avenue (Figure 1; all figures
can be found in Attachment A). The project site is specifically located within the Gusati, California 7.5-minute U.S.
Geological Survey (USGS) topographic quadrangle (USGS 2023a). For the purpose of this report, the area
investigated included the entire 6.00-acre project site plus a 100-foot buffer around the project site boundary, for
a total of approximately 11.75 acres (study area). The study area for the proposed project accounts for both on-site
and off-site biological resources that may be impacted by the project.
2 Project Description
This project site currently contains an industrial warehouse and semi-truck supply docks that will be demolished as
part of this project. The project would involve the construction of a 122,000-square-foot industrial commerce
facility, including 6,000 square feet of office space, 18 loading dock doors, and 1 grade door.
11700 INDUSTRY AVENUE WAREHOUSE PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT
15031 2 FEBRUARY 2023
3 Methods
3.1 Literature Review
To evaluate the natural resources previously documented and potentially occurring within the study area, literature
searches and database reviews were conducted by a Dudek biologist. The database review included the most
recent versions of the California Natural Diversity Database (CNDDB) and special-status species lists (CDFW
2023a–2023e), and the California Native Plant Society’s (CNPS) Inventory of Rare and Endangered Plants (CNPS
2023). These databases were reviewed to identify sensitive biological resources present or potentially present for
the Guasti, California USGS 7.5-minute quadrangle on which the study area is located, and the eight surrounding
quadrangles (Riverside West, Prado Dam, Ontario, Fontana, Mt. Baldy, Devore, Cucamonga Peak, Corona North).
Potential and/or historical drainages and aquatic features were investigated based on a review of USGS
topographic maps (1:24,000 scale) (USGS 2023a), aerial photographs, the U.S. Fish and Wildlife Service (USFWS)
National Wetland Inventory database (USFWS 2023a), and the Natural Resource Conservation Service’s Web Soil
Survey (USDA 2023a).
3.2 Soil Survey Review
According to the Natural Resource Conservation Service’s Web Soil Survey (USDA 2023a), the study area occurs
within the San Bernardino County Southwestern Part (CA677). Tujunga loamy sand, 0% to 5% slopes, is mapped
within the entire study area. Soils in the Tujunga series consist of mixed, thermic Typic Xeropsamments. Tujunga
soils are found on alluvial fans and floodplains at elevations of 6 to 2,000 feet above mean sea level (msl). These
soils are somewhat excessively drained with negligible to low runoff and high saturated hydraulic conductivity.
Tujunga soils are extensively disturbed throughout the central and southern coastal plains and valleys of California.
The entirety of the surface soils observed on the project site have been significantly altered and compacted due to
the construction and development of the existing commercial business. The project site is occupied by an industrial
warehouse. Additionally, no Delhi sands are mapped or present within the study area.
3.3 National Wetlands Inventory Review
A review of the USFWS National Wetland Inventory dataset revealed that no wetland types are mapped within the
study area (USFWS 2023a). An excavated lake feature is mapped approximately 1 mile to the northeast that flows
into an excavated riverine drainage feature and drains to the south toward the Santa Ana River. These mapped
wetlands are well outside of the study area, and no other potentially jurisdictional features occur on the project site.
3.4 Biological Reconnaissance
Dudek biologist Max Murray conducted a general biological reconnaissance of the study area on January 11, 2023.
The survey was conducted from 9:55 a.m. to 11:30 a.m.; weather conditions were moderate with 100% cloud cover,
wind speeds from 0 to 2 miles per hour and a temperature range of 54°F - 55°F. All native and naturalized plant
species encountered in the study area were identified and recorded. The potential for special-status plant and
wildlife species to occur within the study area was evaluated based on the vegetation communities and soils
11700 INDUSTRY AVENUE WAREHOUSE PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT

present. Dudek biologists used the California Department of Fish and Wildlife’s (CDFW) Protocols for Surveying and
Evaluating Impacts to Special Status Native Plant Populations and Natural Communities (CDFW 2018) and List of
Vegetation Alliances and Associates (CDFW 2019), also referred to as the Natural Communities List, to map the
entire study area. Vegetation communities and land covers were delineated to the vegetation alliance level, and,
where appropriate, the association level, based on the Manual of California Vegetation (Sawyer et al. 2009). Some
modifications, such as the Preliminary Descriptions of the Terrestrial Natural Communities of California (Holland
1986; Oberbauer et al. 2008), were incorporated to accommodate the lack of conformity of the observed
communities to those included in these references.
Latin and common names for plant species with a California Rare Plant Rank (CRPR) follow the CNPS Inventory of
Rare and Endangered Plants (CNPS 2023. For plant species without a CRPR, Latin names follow the Jepson
Interchange List of Currently Accepted Names of Native and Naturalized Plants of California (Jepson Flora
Project 2014), and common names follow the Unites States Department of Agriculture’s Natural Resources
Conservation Service Plants Database (USDA 2023b). Latin and common names of animals follow Crother (2017)
for reptiles and amphibians, American Ornithological Society for birds (AOS 2023), Wilson and Reeder (2005) for
mammals, the North American Butterfly Association for butterflies (NABA 2016), and Moyle (2002) for fish.
Dudek biologists also conducted an assessment for the presence of waters or wetlands potentially subject to
regulatory agency jurisdiction, including searching for the presence or drainage features and topographic features
and soils that could support standing water (USGS 2023b). However, a formal wetland delineation was not
conducted as part of the biological reconnaissance.
4 Results
4.1 Study Area Description
The study area is entirely developed and surrounded by industrial development. The study area contains mixed land
uses and existing structures, including commercial facilities for semi-truck loading and supply transportation. No
natural or native vegetation communities were observed in the study area. Ornamental plantings, specifically
pepper tree (Schinus molle), elm (Ulmus sp.), tree of heaven (Ailanthus altissima), Mexican fan palm (Washingtonia
robusta), and blue jacaranda (Jacaranda mimosifolia) along the borders of the study area. Portions of disturbed
land within the study area support non-native (ruderal) vegetation, including a mixture of weedy forbs and grasses.
The study area is relatively flat, with an elevation of approximately 880 feet above msl. Representative photographs
of the study area are provided in Attachment B, Photo Log.
4.2 Vegetation Communities and Land Covers
The study area occurs in an urban setting and consists of predominantly developed land with ornamental planting
and landscaped trees and shrubs. No natural vegetation communities were observed in the study area during the
biological reconnaissance (Figure 1). No exposed soils were observed within the study area that have not been
heavily altered and compacted from landscaping or other human activities. Any natural vegetation communities
that historically occurred in the study area have been removed during previous development of the project site and
immediate surroundings. There are no sensitive vegetation communities within the study area (USFWS 2023b).
11700 INDUSTRY AVENUE WAREHOUSE PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT
15031 4 FEBRUARY 2023
4.2.1 Non-natural and Unvegetated Land Covers
Urban and Developed
The urban and developed mapping unit is not recognized by the Natural Communities List (CDFW 2023e) but is
described by Oberbauer et al. (2008). Developed land typically includes areas that have been constructed upon
and do not contain any naturally occurring vegetation. These areas are generally characterized as graded land with
asphalt and concrete placed upon it. Developed areas mapped in the study area include the existing paved, graded,
compacted, and cleared portions of the project site. The project site consists of approximately 6.00 acres of
developed land, occupied by an industrial warehouse. Soils within the urban and developed mapping unit are
heavily compacted and graded due to frequent vehicle use and landscaping.
4.3 Wildlife
The study area consists of predominantly developed land with scattered ornamental vegetation, and non-native,
ruderal (weedy) vegetation that provides habitat for wildlife species that occur in urbanized settings. Wildlife use
and species diversity were limited during the biological reconnaissance. Bird species observed or detected included
house sparrow (Passer domesticus), California gull (Larus californicus), yellow-rumped warbler (Setophaga
coronate), lesser gold finch (Spinus psaltria), and black phoebe (Sayornis nigricans). No active bird nests were
observed during the field visit; however, the study area could support nesting migratory birds, particularly within the
row of ornamental trees along the southern and western side of the project site. No mammal, insect, amphibian, or
aquatic species were observed within the study area. Additionally, no mammal burrows were observed within the study
area. The complete list of plant and wildlife species observed within the study area is provided as Attachment C,
Species Compendium. Details regarding the potential for special-status species to occur within the study area are
discussed below.
4.4 Special-Status Species
4.4.1 Special-Status Plant Species
Special-status plant species include those listed, or candidates for listing, as threatened or endangered by USFWS
or CDFW, or species identified as rare by CNPS (particularly CRPR 1A, presumed extinct in California; CRPR 1-B,
rare, threatened, or endangered throughout its range; and CRPR 2, rare or endangered in California, more common
elsewhere). A total of 82 special-status plant species were reported in the CNDDB (CDFW 2023a), USFWS (2023c),
and CNPS (2023) databases as occurring within the vicinity of the study area. Attachment D includes the species
lists provided from these database searches that were evaluated as part of this assessment. For each species
evaluated, a determination was made regarding the potential for the species to occur on site based on information
gathered during the field reconnaissance, including the location of the site, habitats present, current site conditions,
and past and present land use.
All of the 52 special-status plant species listed in the CNDDB, CNPS, and USFWS databases as occurring in the
vicinity of the study area were determined to have no potential to occur within the study area based on an evaluation
of the species ranges/elevation and known habitat preferences. Therefore, the project would not result in any
impacts to special-status plants, and no further discussion regarding these species will be provided. The complete
11700 INDUSTRY AVENUE WAREHOUSE PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT
15031 5 FEBRUARY 2023
list of plant species evaluated with a determination of their potential to occur in the study area is provided in
Attachment D1.
4.4.2 Special-Status Wildlife Species
Special-status wildlife include those listed, or candidates for listing, as threatened or endangered by USFWS or
CDFW, or designated as a Species of Special Concern by CDFW (CDFW 2023b, 2023c). A total of 50 special-status
wildlife species were reported in the CNDDB and USFWS databases as occurring in the vicinity of the study area.
Attachment D2 summarizes the database searches for special-status wildlife species that were evaluated as part
of this assessment. For each species evaluated, a determination was made regarding the potential use of the
project site based on information gathering during the field reconnaissance, known habitat preferences, and
knowledge of their relative distributions in the area.
All of the 50 special-status wildlife species listed in the CNDDB and USFWS databases as occurring in the vicinity
of the study area were determined to have no potential to occur based on an evaluation of species ranges/elevation
and known habitat preferences. Therefore, the project would result in no impacts to special-status wildlife, and no
further discussion regarding these species will be provided. The complete list of wildlife species evaluated with a
determination of their potential to occur in the study area is provided in Attachment D2.
4.5 Jurisdictional Waters and Wetlands
The assessment of potential jurisdictional waters in the study area determined that there are no waterways or
drainages within or immediately adjacent to the study area that would be subjected to regulatory agency jurisdiction
(USGS 2023b). A concrete flood control basin (Jurupa Basin) is approximately 1 mile northeast of the study area
and connects to a concrete flood channel approximately 0.5 miles east of the study area that flows south,
connecting to the Santa Ana River but does not intersect any project boundaries (USFWS 2023a). Additionally, there
are no areas capable of supporting wetlands in the study area, and no riparian habitats were observed. Lastly, no
soils mapped in the study area are considered hydric. Therefore, the proposed project would have no impact on the
jurisdictional waters or wetlands.
4.6 Wildlife Corridors and Habitat Linkages
Wildlife corridors are linear features that connect large patches of natural open space and provide avenues for the
migration of animals. Wildlife corridors contribute to population viability by ensuring continual exchange of genes
between populations, providing access to adjacent habitat areas for foraging and mating, and providing routes for
recolonization of habitat after local extirpation or ecological catastrophe (e.g., fires).
Habitat linkages are small patches that join larger blocks of habitat and help reduce the adverse effects of habitat
fragmentation. Habitat linkages provide a potential route for gene flow and long-term dispersal of plants and
animals and may serve as primary habitat for smaller animals such as reptiles and amphibians. Habitat linkages
may be continuous habitat or discrete habitat islands that function as steppingstones for dispersal.
The entire study area is surrounded by development, and no portions of the study area function as a wildlife corridor
or linkage that connect to larger habitat areas in the region, such as the Santa Ana River farther south. Due to the
limited size of the project site and existing on-site and surrounding development, construction of the proposed
project would not result in an impact to any wildlife corridors or habitat linkages.

15031 6 FEBRUARY 2023
4.7 Local Policies and Ordinances
The City of Fontana’s Tree Preservation and Protection Ordinance (Chapter 28, Article III of the City of Fontana’s
Code of Ordinances) regulates the planting, maintenance, protection, and removal of protected tree species within
Fontana. Pursuant to the City of Fontana’s Tree Preservation and Protection Ordinance, tree replacement is required
for project impacts to southern California black walnut (Juglana californica), coast live oak (Quercus agrifolia),
deodar cedar (Deodora cedar), California sycamore (Plantanus racemose), London plane (Plantanus acerifolia) and
windrow trees that would be removed by project construction. However, none of the trees observed within the study
area are within the project site but are planted on the two properties located to the north and south. Project
construction activities will likely not include removal of the trees within the study area however compliance with the
City of Fontana’s Tree Ordinance will be required for the project to reduce impacts related to local ordinances.
4.8 Regional Resource Planning Context
The study area does not occur within any proposed or existing Habitat Conservation Plan or Natural Community
Conservation Plan for local or regional protection of species. Therefore, construction of the project would not result
in an impact related to any proposed or adopted Habitat Conservation Plan or Natural Community Conservation
Plan.
5 Recommendations
This section addresses the anticipated impacts (direct, indirect, and cumulative) to biological resources that would
result from implementation of the proposed project. The following recommendations would reduce any potential
impacts related to the thresholds provided in California Environmental Quality Act Guidelines Section 15064(b) and
Appendix G, Environmental Checklist, to less than significant. Recommendations are included for the evaluation of
the project’s impacts on potentially affected resources, such as nesting birds and local policies and ordinances.
5.1 Nesting Birds
The ornamental plantings within the study area may provide suitable nesting, roosting and foraging habitat for
migrator and nesting birds. As such, construction activities should be avoided during the nesting season (generally
February 1 through August 30) to ensure compliance with the federal Migratory Bird Treaty Act and California Fish
and Game Code Section 3500 et seq and reduce potential impacts to nesting birds. If avoidance of the nesting
season is not feasible, then a pre-construction nesting bird survey shall be conducted by a qualified biologist to
ensure that birds are not engaged in active nesting within 500 feet of the project’s construction limits. If nesting
birds are discovered during pre-construction surveys, then the qualified biologist will identify an appropriate buffer
where no construction activities will be allowed to occur until after the birds have fledged from the nest.
Construction activities may take place in other areas on the project site, outside other the nest avoidance buffer,
only at the discretion of an on-site monitoring biologist.

5.2 City of Fontana Tree Preservation and
Protection Ordinance
A tree removal permit must first be obtained from the community development department prior to removal of any
heritage or significant tree protected on the study area by the City’s Tree Preservation and Protection Ordinance
(City of Fontana 2022). If project activities will potentially impact trees adjacent to the project site, a tree inventory
is recommended to be conducted by a certified Arborist prior to project implementation to identify the location,
number, species, diameter, and height of all on-site heritage and significant trees in relation to proposed project
improvements. An Arborist Report should be prepared by the certified arborist, wherein all applicable on-site trees
that would be expected to be removed by the project will be evaluated, and outline replacement procedures for all
eligible trees to be removed from the project site.
Pursuant to the City’s Code of Ordinances, tree replacement may be required for potential impacts to significant
and heritage trees on the study area that would be removed by vegetation clearing for construction of the proposed
project. Tree replacement ratio is dependent on overall condition and size of the protected trees on site. Heritage
and significant tree preservation on the site is preferred to relocation or replacement.
