RE:

Biological Resources Assessment,

Jurisdictional Waters Delineation

Rialto Storm Drain, Rialto, CA

Dear Tom:

Jericho Systems, Inc. (Jericho) is pleased to provide this letter report that details the results of a general Biological Resources Assessment/Jurisdictional Waters Delineation (BRA/JD) for a proposed
storm
drainage system

located

in the City of Rialto.

J
ericho Systems, Inc. (Jericho) is pleased to provide this letter report that details the results of a general Biological Resources Assessment (BRA) that includes habitat suitability assessments for nesting birds, Burrowing owl (
Athene
cunicularia
) [BUOW],
Delhi sands flower
-
loving fly (
Rhaphiomidas terminatus
abdominalis
)

[DSF]
, small mammals such as the San Bernardino Kangaroo Rat ( Dipodomys merriami
parvus
) [SBKR] and Los Angeles Pocket mouse (
Perognathus longimembris brevinasus
) [LA
PM] and a
Jurisdictional Waters Delineation (JD) for the proposed construction and operation of the
Rialto Storm
Drain
Project (Project).

This report is designed to address potential effects of the proposed Project to designated Critical Habitats and/o
r any species currently listed or formally proposed for listing as endangered or threatened under the federal Endangered Species Act (ESA) and the California Endangered Species Act (CESA), or species designated as sensitive by the California Department of Fish and Wildlife (CDFW), or the California
Native Plant Society (CNPS). Attention was focused sensitive species known to occur locally. This report also addresses resources protected under the Migratory Bird Treaty Act, federal Clean Water Act (CWA) regu
lated by the U.S. Army Corps of Engineers (USACE) and Regional Water Quality Control Board (RWQCB) respectively; and Section 1602 of the California Fish and Game Code (FCG) administered by the CDFW.

PROJECT LOCATION

The proposed project is located at
Cactus Basin (just west of Cactus Avenue and Baseline Road) connecting to Baseline Road south of Cactus Basin and traveling west within Baseline Road to just west of Tamarind Avenue within the City of Rialto, CA
.

The Project is mostly located within existing
roadways, though Cactus Basin (which the proposed
p
roject will connect the new storm drain to) is
located on land designated for Open Space Resource Use.

The project is located in Section 34
Township
1 North
, R
ange
5 West
within the Fontana
USGS Topo 7.5
-
minute series maps
. The project is primarily
linear

with an approximate Lat/Long of

34.124043
,
-
117.388063

at the eastern portion of the project and

34.121298
,
-
117.422797

at the western portion of the project.

PROJECT UNDERSTANDING

The project consists of
installing an approximately
2 -
mile

or 11,000 lineal feet

(LF)
storm drain system
within Baseline Road that would
captur
e

flows north of Baseline Road. The storm drain line starts at the

Tamarind Avenue/Baseli
ne Road intersection and runs along Baseline Road to the outlet at Cactus Basin No. 3. The City of Rialto Master Plan of Drainage was used to size the storm drain system to improve drainage systems
I
n the City of Rialto.

The new storm drain will be develop
ed within a reinforced
concrete box (RCB) that will vary in size between 6’ x 12’, 7’ x 7’, and 3’ x 10’ depending on the location within the new storm drain alignment. The majority of the storm drain footprint (located within Baseline Road) will be constr
ucted as a 72” reinforced concrete pipe (RCP), though a portion of the easternmost section of the alignment, which leaves from Baseline Road to Cactus Basin, will vary in size as either a 72”, 84”, 48”, 36”, or 30” RCP.

The project site corresponds to th
e proposed storm drain “Line D” as described in the City of Rialto Master Plan of Drainage. The project area is located within the Renaissance Development ,

which consist
s

of the redevelopment of the Rialto
A
irport and the surrounding areas. The
Renaissance Specific Plan was
used to get additional information for Line D and meet drainage facility requirements. Subarea D is bounded by 210 freeway on the north, Baseline Road on the south, Cactus Avenue on the east, and Palmetto Avenue on the west. O
verland flow travels in southeastern direction in the southern portion of the Renaissance site before it is captured by Line D and outlets to Cactus Basin No. 3.

Flows leaving Basin No. 3 continue on to Basin 1 and 2 and Rialto Channel, which ultimatel y discharges
to the Santa Ana River. Outflow from the Cactus Basin System are limited due to the poor downstream channel capacities.

The proposed project will install one of three Alternative Alignments that will connect the new Baseline Road storm drain
alignment with Cactus Basin.

The project will retrofit an existing 36” RCP outlet to the larger structure. Energy dissipation measures (such as rip rap pad, baffle) may

be i
nstalled

at the outlet
, to
control erosive damage from the higher volume discharged

from the new pipeline.

SETTING

The City of
Rialto sits at the base of the Cajon Pass, where high winds are common

meteorological events
within the region.

The climate in the region is typically characterized as Mediterranean
. Typical rainfall
averages approximately 1
7 inches per year. Hydrologically, the
Project site
is within the
C
hino

Hydrologic Sub
-
Area (HSA 80
1 .
21 ) which comprises a
17,765
-
acre drainag
e area within the larger
Middle Santa Ana River

Watershed (HUC 1807020
30804
).

The subject parcel is situated in a
developing

area of the Inland Valleys ecoregion
.

Most of the project occurs along Baseline Road, and the stretch of road consists of residential and commercial development with ornamental vegetation that is regularly gardened. Plots of undeveloped land adjacent to Baseline Road consist primarily of
ripgu
t brome (
Bromus diandrus)

and wild oat (
Avena
fatua
)
.

Habitat
within
and adjacent to
the Cactus Basin portion
consists of degraded alluvial fan sage
scrub
.

The s
tretch that parallels the
northbound portion of
fence line consists of a

steep grade (~70 deg
ree) with
evidence of standing water. The northeast portion of the basin consists of a shallow grade (~10 degree).

METHODS

As stated above, the objective of this document is to determine whether the Project area supports special status or otherwise sensitive species and/ or their habitat, and to address the potential effects associated with the Proposed project on those resou
rces. The species and habitats addressed in this document are based on database information and field investigation.

These sources include:

•

U.S. Fish and Wildlife (USFWS) threatened and endangered species occurrence GIS overlay;

•

USFWS Information for

Planning and Consultation System (IPaC);

•

California Natural Diversity Database (CNDDB)
Rarefind 5
);

•

CNDDB
Biogeographic Information and Observation System (BIOS) ;

•

California Native Plant Society Electronic Inventory (CNPSEI) database;

•

Calflora Database;

•

USDA Natural Resources Conservation Service (NRCS) Web Soil Survey;

•

USFWS National Wetland Inventory;

•

Environmental Protection Agency (EPA) Water Program “My Waters” data layers

•

USFWS Designated Critical Habitat Maps

We also reviewed other
available technical information on the biological resources of the site, including

previous trapping surveys and discussed recent findings with researchers in the field.

Jericho biologist Christian Nordal conducted a general biological resources assessmen t on
March

1, 2019,
with an emphasis on special
-
status species known to occur in the area. Mr. Nordal has advanced degrees and multiple years of experience surveying biological resources within Southern California. Mr. Nordal conducted the systematic and comprehensi
ve survey during calm weather, between the hours of
77 a.m.
and 11 a.m. Weather conditions during the survey consisted of clear skies with temperatures ranging from 65 degrees Fahrenheit (° F) to 73° F and light wind <5 mph.

On
March 30
, 2019, Jericho

ecologist Shay Lawrey performed a follow up site assessment to evaluate the potential to support for

DSF, BUOW

and small mammals to occur on site, specifically the federally endangered SBKR and State species of special concern LAPM and federally threat ened CAGN. Ms.

Lawrey has advanced degrees in biology, is permitted to trap and handle SBKR and has two decades of experience with surveying for sensitive small mammals and birds.

Wildlife species were detected during field surveys by sight, calls, track s, scat, or other sign. In addition
to species observed, expected wildlife usage of the site was determined per known habitat preferences of regional wildlife species and knowledge of their relative distributions in the area. The focus of the faunal specie
s surveys was to identify potential habitat for special status wildlife within the project area.

Disturbance characteristics and all animal sign encountered on the site are recorded in the results section.

The
Project area

was also evaluated for the pre
sence of jurisdictional waters, i.e. waters of the U.S. as regulated by the USACE and RWQCB, and/or streambed and associated riparian habitat as regulated by the CDFW.

Evaluation of potential federal jurisdiction followed the regulations set forth in 33CF R part
328 and the USACE guidance documents and e
valuation of potential State jurisdiction followed guidance in the Fish and Game Code and A Review of Stream Processes and Forms in Dryland Watersheds (CDFW, 2010).

RESULTS

The project site is
primarily

a multi
-
use urban setting, with the Cactus Basin component holding the only vegetation not actively managed by landscaping. The habitat adjacent to the north -
bound fencing in
Cactus Basin is high disturbance new growth, whereas the habitat in the northeas t corner of the project
site is high disturbance alluvial fan sage scrub.

Habitat within

or adjacent to

the
north
-
bound
portion
on the easternmost part
of
the
P
roject
alignment at
Cactus Basin
consists primarily of

foxtail

(
Hordeum murinum
)
,

wild oat

(
Avena fatua
)
, stinging nettle
(
Urtica urens
), coastal heron’s bill (
Erodium cicutarium
)

and common fiddleneck (
Amsinckia
intermedia
)
.

Shrubs become increasingly numerous the further north into the basin. Those shrubs
are
primarily

California

buckwheat (
Eriogonum fasciculatum
)
and

California sagebrush

(
Artemesia
californica
)
.

Adjacent to the northernmost

portion of the basin

is
degraded
alluvial fan sage scrub that
consists of interspersed California sagebrush, California buckwheat, foxtail, ripgut ( Bromus diandrus
), a
single holly
-
leaf cherry (
Prunus ilicifolia
) shrub, and a single beavertail cactus (
Opuntia basilaris var.
basil
aris
).

Vegetation on or adjacent to all other
aspects
of the project are ornamental landscaped shrubs
or ruderal vegetation composed of ripgut and foxtail.

Common wildlife was observed during survey which included side
-
blotched lizard (
Uta
stansburiana
)
,

western meadowlark
(
Sturnella neglecta
), white
-
crowned sparrow (
Zonotrichia leucophrys
),
house finch
(
Haemorhous mexicanus
),
and

American crow

(
Corvus brachyrhynchos
)
.

The soil conditions within the Project are
composed of loam and are not
Delhi sands. The loamy soils
not
suitable to support Delhi sands flower
-
loving fly [DSF]
. F
urther investigation
in to DSF
is not warranted
or recommended.

Due to the
habitat
conditions at
the east end, northbound portion of the alignment that
approaches C
actus
Basin
,

and
due to

previous
records

of
SBKR

in Cactus Basins
,
there
remains a moderate
potential for
occurrence of

SBKR

and LAPM
.

Further the

Project site

at Cactus Basin is
potentially suitable for
BUOW
.

San Bernardino Kangaroo Rat

(SBKR)

The SBKR is one of several kangaroo rat species in its range. The Dulzura kangaroo rat ( Dipodomys

simulans
), the Pacific kangaroo rat (
Dipodomys agilis
) and the Stephens kangaroo rat (
Dipodomys

stephensi
) can occur in areas occupied by the SBKR, b
ut these other species have a wider habitat range.

The habitat of the SBKR is confined to primary and secondary alluvial fan scrub

habitats, with sandy soils deposited by fluvial (water) rather than aeolian (wind) processes. Burrows are

dug in loose soil,
usually near or beneath shrubs. SBKR, are confined to inland valley scrub communities, and more particularly, to scrub communities occurring along rivers, streams and drainage.

Most of these drainages have been historically altered as a result of flood co ntrol efforts and the resulting
increased use of river resources, including mining, off -
road vehicle uses and road and housing
development. This increased use of river resources has resulted in a reduction in both the amount and quality of habitat availabl
e for the SBKR. The past habitat losses and potential future losses prompted the emergency listing of the SBKR as an endangered species.

The Cactus Basin

aspect of the Project
area does c
ontain habitat elements typically associated with
SBKR. Further, small mammal burrows
were noted of

appropriate size, shape or aspect for SBKR
s.

There are documented occurrences of this species
within Cactus Basins.

For these

reasons absence
cannot be pr
esumed without a focused presence/absence survey.

Los Angeles Pocket Mouse (LAPM)

The LAPM is one of two pocket mice found in this area of San Bernardino County. Both the LAPM and the San Diego pocket mouse occupy similar habitats, but the San Diego poc ket mouse has a wider range
extending south into San Diego County. The habitat of the LAPM is confined to lower elevation grasslands and coast sage scrub habitats, in areas with soils composed of fine sands. The present known distribution of this species e
xtends from Rancho Cucamonga east to Morongo and south to the San Diego County border. LAPM forages in open ground and underneath shrubs. Pocket mice in general dig burrows in loose soil, although this has not been completely documented for this subspeci es. The LAPM
is listed as a Critical Species of Concern by the CDFW.

The Project site contains habitat marginally suitable habitat for LAPM and there are several documented occurrences of LAPM
in the near vicinity of the Cactus Basin
.

No protocol surveys

were conducted as
part of this assessment
, therefore presence or absence of LAPM was not determined, only their potential to occur. Potential of occurrence for LAPM is moderate. Presence or absence of LAPM cannot be presumed without a focused presence/ab
sence survey..

Burrowing owl (BUOW)

BUOW are known to occur locally within suitable habitat areas.

BUOW is a
ground
-
dwelling

owl
typically found in arid prairies, fields, and open areas where vegetation is sparse and low to the ground.

The BUOW depends on the presence of mammal burrows, i.e. ground squirrel burrows to provide shelter from predators, inclement weather and to pro
vide a nesting place. They are also known to make use of human
-
created structures, such as cement culverts and pipes, for burrows. They feed primarily on insects but will also take small rodents, birds, and reptiles. They are active during the day and nigh t, generally
observed in the early morning hours or at twilight. The breeding season for BUOW is February 1 through August 31. The BUOW is not listed under the State or Federal Endangered Species Act but is considered both a State and federal SSC. The BUO
W is a protected by the international treaty under the Migratory Bird Treaty Act
(MBTA)
of 1918 and by State law under the California Fish and Game Code (CDFG Code #3513 & #3503.5).

Per the definition provided in the
2012 CDFG Staff Report on
Burrowing Owl Mitigation
, “Burrowing
owl habitat generally includes, but is not limited to, short or sparse vegetation (at least at some time of year), presence of burrows, burrow surrogates or presence of fossorial mammal dens, well -
drained soils,
and abu
ndant and available prey.”

Therefore, the
Cactus Basin aspect of the P
roject
area

and immediate
vicinity contain
s

suitable habitat for this species
.

No evidence of BUOW was found in the survey area. No burrows of appropriate shape size or aspect for BUOW

or BUOW pellets, feathers or whitewash were found on site.

No BUOW individuals were
observed.

Therefore, BUOW are considered absent from the site at the time of surveys.

Nesting Birds and Raptors

The site is suitable for use by raptors for foraging purposes.

The project site and immediate surrounding
areas do contain habitat suitable for nesting birds in general, including the shrubs on site.

Nesting birds are protected under the MBTA
which pro
vides protection for nesting birds that are both
residents and migrants whether they are considered sensitive by resource agencies.

The MBTA makes it
unlawful to take, possess, buy, sell, purchase, or barter any migratory bird listed under 50 CFR 10, incl
uding feathers or other parts, nests, eggs, or products, except as allowed by implementing regulations (50 CFR 21). The direct injury or death of a migratory bird, due to construction activities or other construction
-
related disturbance that causes nest a
bandonment, nestling abandonment, or forced fledging
would be considered take under federal law. The USFWS, in coordination with the CDFW administers the MBTA. CDFW’s authoritative nexus to MBTA is provided in FGC Sections 3503.5 which protects all birds

of prey and their nests and FGC Section 3800 which protects all non -
game birds that occur
naturally in the State.

Jurisdiction Waters

Cactus Basin is a jurisdictional water subject to Sections 404 and 401 of the CWA and Section 1600 of the FGC. Modifi
cations within the basin will likely require permits from the USACE, RWQCB and CDFW.

CONCLUSIONS

S
everal occurrences of SBKR
and LAPM
are documented in the immediate vicinity of the
east end of the
Project
area
. Although the habitat conditions are
ma
rginal
for
these species,

absence
of either species
cannot be determined without focused survey.

Habitat suitability of BUOW is marginal along the alignment where there is vacant land. This species was not observed during survey and no sign of the
presence was found. Prior to construction a 30
-
day
survey is warranted and recommended.
.

The
vegetation on

site
does
have a potential to support nesting birds and
foraging
raptors such as red
-
tailed hawks.

Therefore, to reduce the potential impacts to

nesting birds, the following is recommended:

•

Bird nesting season generally extends from February 1 through September 15 in southern California and specifically, April 15 through August 31 for migratory passerine birds. To avoid impacts to nesting
birds (common and special status) during the nesting season, a qualified Avian Biologist will conduct pre‐construction Nesting Bird Surveys (NBS) prior to project‐related disturbance to nestable vegetation to identify any active nests. If no active nests a re found, no
further action will be required. If an active nest is found, the biologist will set appropriate no‐ work buffers around the nest which will be based upon the nesting species, its sensitivity to disturbance, nesting stage and expected types, int
ensity and duration of disturbance. The nests
and buffer zones shall be field checked weekly by a qualified biological monitor. The approved no‐work buffer zone shall be clearly marked in the field, within which no disturbance activity shall commence until

the qualified biologist has determined the young birds have successfully fledged and the nest is inactive.

Jericho appreciates the opportunity to continue to be of service.

The study is part of the environmental review process for the project
. The City of Rialto, as
the project sponsor and
the lead agency, required the study in compliance with the California Environmental Quality Act (C
EQA
)
. The purpose of the study is to p
rovide the City with the
necessary information and analysis to determine whether the proposed project would cause substantial adverse changes to any “historical resources,” as defined by CEQA, that may exist in or nea
r the project area. In order to identi
fy such resources, CRM TECH conducted a
historical/archaeological resources records search, pursued historical background research, consulted with the Native American representatives, and carried out a systematic
fiel
d survey.

The re
sults of the records

search
indicate that

T
he field survey and the historical background res
earch

reveal that

four of these
five sites

are
no longer extant today,
having
evidently

been

removed
during

subsequent residential and
commercial developments

at their former locations
.

The remaining site,
36 -
015497
, represents
the
San Bernardino Baseline
, embodied by Bas
eline Road in the project vicinity
. As a part of
the basis for
all land surveys and titles in southern California since

1853,
the
San Bernardino
Baseline

was
officially
designated a California Point of Historical Interest (CPHI -
SBr
-
12) in

1973
.

As such,

Site
36 -
015497 meets the definition of a “historical resource” under CEQA provisions.

The historic value of
Site
36 -
015497
, however, is symbolic in nature and is derived from the conceptual line across the landscape instead of the exist ing roadway, a he
avily traveled major
thoroughfare of entirely modern character and appearance.

Therefore
,

the
current
configuration and physical features of
Baseline Road

do not contribute to the historic
significance of
the site
.

Since
Site
36 -
015497

e
xists in the proj
ect area largely on paper

only
,
this study concludes that the proposed project has no potential to affect the

significance or
integrity

of this “historical resource.”

During the course of the Native American
contacts
, the State of Califor
nia Native American
Heritage Commission
reported the presence of unspecified Native American cultural resource(s) in the project
vicinity

but

referred further
inqui
ries

the Gabrieleño Band of
Mission Indians
–
Kizh Nation.

In sub
sequent correspondence,
h
owever,
the Gabrieleño Band
of Mission Indians
–
Kizh Nation

did not provide any further information on such resources.

A
ccord
ing to

CEQA guidelines, the identification of potential “tribal cultural resources” is beyond the scope of

this study and needs to
be addressed through government
-
to
-
government
consultations

between the City of Rialto and the pertinent Native American groups pursuant to Assembly Bill 52.

Based on these findings, CRM TECH recommends to the City of Rialto a preliminary
conclusio
n

of
No Impact

on cultural resources, pending the completion of
the City
’s
government
-
to
-
government

consultation

process

with
local
Native American

tribes
. No
additional cultural resources investigation is recommended for the project unless construction

plans undergo such changes as to include areas not covered by this study. However, if buried cultural materials are encountered inadvertently during any e arth
-
moving operations
associated with the project, all work within 50 feet of the discovery should be halted or diverted until a qualified archaeologist can evaluate the nature and significance of the finds .

11 INTRODUCTION

Between

March and
May

2019, at the request of Tom Dod
son & Associates, CRM TECH performed
a cultural resources study
for the proposed
Rialto Baseline Storm Drain Project

in the City of Rialto,
San Bernardino County, California

(Figure 1)
.

The project seeks

to upgrade
current

drainage
infrastructure
along
Ba
seline
Road

from
a retention basin known as
Cactus Basin
No. 3
west to
the
intersection
with
Tamarind Avenue
. The subject
property of the study consists of

a
pproximately

2.25 linear miles

of
storm drain
right
-
of
-
way lying m
ostly within the existing right
-
of
-
way of
Baseline Road, in
Sections
3 2
-
3 4

of T1N R5W and Sections 3
-
5 of T1S R5W, San Bernardino
Baseline and Meridian

(Figures 2, 3)
.

The study is part of the environmental review process for the project
. The City of Ri
alto, as
the
project sponsor and

the lead agency, required the study in compliance with the California Environmental Quality Act (CEQA
; PRC §21000, et seq.
)
. The purpose of the study is to provide
the City with the necessary information and analysis to de termine whether the proposed pro
ject
would cause substantial adverse changes to any “historical resources,” as defined by CEQA, that may exist in or near the project area.

In order to identify such resources, CRM TECH conducted a historical/archaeological resources records search, pur
sued historical background research, consulted with the Native American representatives, and carried out a
systematic
field survey.

The follow
ing report is a complete account
of the methods, results, and final conclusion of the study.

SETTING

CURRENT NATURAL SETT
ING

The
City of Rialto

is situated

the
east
ern
portion

of the San Bernardino Valley, a broad inland
valley defined by the San Gabriel a
nd San Berna
rdino Mountain Ranges on the north and a series
of low rocky hills on the south.

The environment of the region is characterized by its temperate Mediterranean climate, with the average maximum temperature in July reaching above 90

degrees

Fahr
enheit and t
he average minimum temperature in January hovering around 35

degrees
. Annual
rainfall is typically less than 20 inches, most of which occurs between November and March.

As mentioned above, most of the project alignment lies within the Baselin e Road

right
-
of
-
way
,
while the easterly end

of the project
, from Baseline Road to
the
Cactus Basin
s
,
follows the course
of an unpaved access road (Figure 3).

This segment of Baseline Road,

a heavily traveled
local

thoroughfare
, is lined
predominantly by

sub
urban

r
es
idential neighborhoods

on the south and by
recent
commercial and
warehouse

developments on the north
, with some vacant land and a few
older residences of rural character still present

(Figure
s

3 , 4
).

The terrain in the vici
nity is
relatively
level,

with

slight

incline to the west
, and the
elevation
s in
the project area range approximately from

1,360
feet
to 1,415 feet above

mean

sea level.

Virtually
the entire project area has been disturbed by past construction activitie s associated with
Baseline
Roa
d, the retention basins, the access road, underground utilities, nearby buildings, and other urban development. The existing
vegetation
in and around

the project area consisted
mainly
of
landscaping plants

with some

small gra
sses and shrubs
, and little ve
stige of the native landscape
remains

(Figure 4)
.

CULTURAL SETTING

Prehistoric Context

The earliest evidence of huma
n occupation in inland southern California was discovered below the surface of an alluvial fan in
the northern portion of the Lakeview Mountains, overlooking the Sa n

Jacinto Valley, with radiocarbon dates clustering around 9,500 B.P. (Horne and McDougall 2008).

Another site found near the shoreline of Lake Elsinore, close to the confluence of Temescal

Wash
and the San Jacinto River, yielded radiocarbon dates between

8,000 and 9,000 B.P. (Grenda 1997).

Additional sites with isolated Archaic dart points, bifaces, and other associated lithic artifacts from the same age range have been found in the nearby

Cajon Pass area, typically atop knolls with good
viewsheds (Basga
ll and True 1985; Goodman and McDonald 2001; Goodman 2002; Milburn et al. 2008).

The cultural history of southern California has been summarized into numerous chronologies, including the w
orks of Chartkoff and Chartkoff (1984), Warren (1984), and others.

The prehistory
of Riverside County specifically has been addressed by O’Connell et al. (1974), McDonald, et al. (1987), Keller and McCarthy (1989), Grenda (1993), Goldberg (2001), and Horn e and McDougall
(2008). Although the beginning and ending dates o
f different cultural horizons vary regionally, the
general framework of the prehistory of inland southern California can be divided into three primary periods:

•

Paleoindian Period (ca. 18,0
00 -
9,000 B.P.): Native peoples of this period created fluted spear
head bases designed to be hafted to wooden shafts. The distinctive method of thinning bifaces and spearhead preforms by removing long, linear flakes leaves diagnostic Paleoindian markers at

tool
-
making sites. Other artifacts associated with the Paleoindia n toolkit include
choppers, cutting tools, retouched flakes, and perforators. Sites from this period are very sparse across the landscape and most are deeply buried.

•

Archaic Period (ca. 9,
000
-
1,500 B.P.): Archaic sites are characterized by abundant lithi c scatters
of considerable size with many biface thinning flakes, bifacial preforms broken during manufacture, and well
-
made groundstone bowls and basin metates. As a consequence of making dart points, many biface thinning waste flakes were generated at i ndividual production stations,
which is a diagnostic feature of Archaic sites.

•

Late Prehistoric Period (ca. 1,500 B.P.
-
contact): Sites from this period typically contain small lithic scatt
ers from the manufacture of small arrow points, expedient groundst one tools such as
tabular metates and unshaped manos, wooden mortars with stone pestles, acorn or mesquite bean granaries, ceramic vessels, shell beads suggestive of extensive trading networ ks, and steatite
implements such as pipes and arrow shaft straight
eners.

Ethnohistoric Context

Ethnographically, the
present
-
day Rialto

area lies

between

the traditional territor
ies

of the Serrano
and the Gabrielino, which adjoined and overlapped with each other, at least during the Late Prehistoric and Protohistoric

Periods.

The homeland of the Gabrielinos, probably the most
influential Native American group in aboriginal southern California (Bean and Smith 1978a:538),
was centered in the Los Angeles Basin and reached as far east as the San Bernardino -
Riverside area
.

The homeland of the Serranos was centered in the San Bernardino Mountains but also included the slopes and lowlands
on the flanks of the mountain range and the southern portion of the Mojave Desert.

Whatever the linguistic affiliation, Native Americans

in and around the
Rialto

area exhibited similar
social organization and resource procurement strategies. Villages wer e based on clan or lineage
groups. Their home/base sites are marked by midden deposits, often with bedrock mortars. During their season
al rounds to exploit plant resources, small groups would migrate within their traditional territory in search of specif
ic plants and animals. Their gathering strategies often left behind signs of special use sites, usually grinding slicks on bedrock bould ers, at the locations of the resources.

As early as 1542, the Gabrielino were in contact with the Spanish during the h istoric expedition of
Juan Rodríguez Cabrillo, but it was not until 1769 that the Spaniards took steps to colonize Gabrielino territory.

Shortly afterwards, most of the Gabrielino people were incorporated into Mission San Gabriel and other missions in sou
thern California. The Serrano were brought into the
mission system during the 1810s, when an
asistencia

of Mission San Gabriel was estab
lished in
present
-
day Loma Linda. Due to introduced diseases, dietary deficiencies, and forceful reduction, Gabrielino

and Serrano population dwindled rapidly. By 1900, the Gabrielino had almost ceased to exist as a culturally identifiable group (Bean an
d Smith 1978a:540). The Serrano, meanwhile, were
mostly settled on the San Manuel and the Morongo Indian Reservations (Bean and Smith
1978b:573).

Historic Context

In 1772, three years after the beginning of Spanish colonization of Alta California, Pedro

Fages,
comandante

of the new province, and a small force of soldiers under his command became the first Europeans to s
et foot in the San Bernardino Valley

(Beck and Haase 1974:15)
. They were followed
in the next few years
by two other famed Spanish explo
rers, Juan Bautista de Anza and Francisco
Garcés, who traveled through the valley in the mid
-
1770s

(
ibid.
)
. Despite th
ese early visits, for the
next 40 years the inland valley received little impact from the Spanish colonization activities in Alta Califor
nia, which were concentrated predominantly in the coastal regions.

Following the establishment of Mission San Gabriel in 1771, the San Bernardino Valley became nominally a part of the landholdings of that mission.

The name “San Bernardino” was bestowed o
n
the region at least by 1819, when a mission
asistencia

and an asso
ciated rancho were officially
established under that name in the eastern end of the valley (Lerch and Haenszel 1981).

After
gaining independence from Spain in 1821, the Mexican government

began in 1834 the process of
secularizing the mission system in Alt
a California, which in practice meant the confiscation of the Franciscan missions’ vast land holdings, to be distributed later among prominent citizens of the province. During the 1830s a
nd 1840s, several large land grants were made around present -
day
Ria
lto
(Beck and Haase 1974:
38). However, most of what is now the City of Rialto, including the project area, was not included in any of these land grants, and thus remained unclaimed public

land
when California was annexed by the U.S. in 1848.

Used primari
ly as cattle ranches, the area around Rialto saw little development until the mid -
19th
century, when a group of Mormon settlers from Salt Lake City founded the town of San Bernardino in 18

51. After the completion of the Southern Pacific Railroad and the c ompeting Atchison, Topeka
and Santa Fe Railway in the 1870s
-
1880s, a phenomenal land boom swept through much of southern California, ushering in a number of new settlements in the San Bern ardino Valley. In 1887, the
Semi
-
Tropic Land and Water Company purc
hased a large tract of land near the mouth of Lytle
Creek, together with the necessary water rights to the creek, and laid out the townsites of Rialto, Bloomington, and Rosena (now Fontana
;
Ingersoll 1904:619; Brown and Boyd 1922:249
-
250
)
.

With the collap
se of the 1880s land boom, the Semi
-
Tropic Land and Water Company lost its
holdings to its creditors in 1896, and the entire enterprise was thrown into financial turmoil

(Schuiling 1984:90
, 102)
. The community of Rialto survived, thanks largely to the new ly
established citrus industry. Throughout the late 19th and early 20th centuries, Rialto grew steadily as one of San Bernardino Valley’s “citrus showcases,” with most of its residents de voted primarily
to the cultivation of the navel orange (Brown and Bo
yd 1922:249
-
250). Since the mid
-
20th century,
the Rialto area became increasingly urbanized
—
and its economic livelihood diversified
—
along with
the rest of southern California. Today, the

area’s once thriving citrus industry is more a part of its cultural

heritage than a force in the local economy.

RESEARCH METHODS

RECORDS SEARCH

On
March 20, 2019
,
CRM TECH archaeologist Ben Kerridge
completed

the
historical/
archaeological resources r
ecords search
at the South Central

Coastal Information Center (SCCIC),
California State University, Fullerton
.

During the records search, Kerridge examined maps, records, and electronic databases at the SCCIC
for previously identified cultural resources a
nd existing
cultural resources rep
orts within a one
-
mile radius of the project area.

Previously identified cultural
resources include properties designated as California Historical Landmarks, Points of Historical Interest, or San Bernardino County Histori
cal Landmarks, as well as those li
sted in the National
Register of Historic Places, the California Register of Historical Resources, or the California Historical Resources Inventory.

NATIVE AMERICAN

CONSULTATION

On
March 14, 2019
, CRM TECH submitted a written request to t
he State of California Native
Amer
ican Heritage Commission (NAHC) for a records search in the commission’s Sacred Lands File.

Following the NAHC’s recommendations and previously established consultation protocol, CRM TECH further
contacted a total of
nine

nearby tribes

in writing on March
28 for additional
information on potential Native American cultural resources in the vicinity. Correspondence between CRM TECH and the Native American representatives is summarized below and
attached to
this report in Ap
pendix
2 .

FIELD SURVEY

On
March 22, 2019
, CRM TECH archaeologist Daniel Ballester
carried out the

field survey of the
project area
.

The portion of the project area along the
dirt access road
between

the
Cactus Basin
s

and
Baseline Road

was surveyed at an

intensive
level by walking two parallel transects placed on
either side of the alignment, and the rest of the project area, lying within the Baseline Road

right
-
of
-
way, was surveyed at a reconnaissance level from a

slow
-
moving

motor vehicle.

In this way,

the
ground

surface in the entire project area was systematically examined for any evidence of human activities dating to the prehistoric or historic period (i.e., 50 years or older).

V
isib
ility

of the native
ground surface

was poor within the
Baseline Ro
ad

right
-
of
-
way but
good (80 percent)
along

the dirt
access
road
.

RESULTS AND FINDINGS

RECORDS SEARCH

According to
SCC
IC records
,

five

previous cultural resources studies completed between
1995

and
2016 have
evidently included
various
portions of the
pro
ject area

(Figure 5)
. As a result of these
studies,
one

historical/archaeological site
, designated
36 -
015497

in the

California Historical
Resources Inventory
, was previously

recorded
as lying partially within the project
area
. The site
represents the
San Bernardino Baseline,
which is
embodied by Baseline Road in the project vicinity
,
and

was
officially
designated a California Point of Historical Interest (CPHI -
SBr
-
12) in 1973

(
OHP

1973)
.

In add
ition to
36 -
015497
,
four other sites were
previously

recorded on prop
erties adjacent to
the project area. The four adjacent sites are listed below:

36 -
010659 (CA
-
SBR
-
10659H)

sparse refuse scatter

36 -
010908 (CA

-

multi
-
origin refuse dumping site

Outside the project area but within
the

one
-
mile radius, SCCIC records show
more than 20

other

studies
on

various tracts of land
and linear features
,

including
at least four

studies
on
adjacent
prop
erties

(Fig
ure 5
)
.

In all, approximately
75 percent of the land within the scope of the records
search has been surveyed, result
ing

in the identification of
seven

addition
al sites.

Like the five sites
within or adjacent to the project boundaries, a
ll

of
the
se

sit
es

date
d

to the historic period
.

A
mong
them were

buildings,
structural foundations, water storage tanks,

refuse scatters,
and

the
former
Rialto Municipal Airport
.

None of these
seven
sites was found
in the immediate vicinity of

the
project area
.

Therefore,
none of them requires further c
onsideration during this study.

HISTORICAL BACKGROUN

D RESEARCH

Historical maps demonstrate that
in the mid
-
19th century, when the U.S. government conducted the
earliest
systematic
land surveys in the San

Bernardino Valley, the only man
-
made features known to
be present in the project vicinity were a few winding roads (
Figure 6)
.

The most notable among
these was the forerunner of present
-
day Baseline Road, which was then a part of
a

main
thorou
gh
fare

betw
een San Bernardino and Los Angeles. The road was blazed by
the
Mormon
settlers

in San Bernardino in the mid
-
1850s and was

laid out generally along
the
San Bernardino
Baseline

(
Haenszel 1979:31
). In the vicinity of the project area, however, the actual ro ute of that
road was roughly a half
-
mile south of the b
aseline

and well outside the project area (
Figure 6)
.

By the late
19th century, the early roads had been replaced by a grid of widely spaced roads lined by scattered buildings, in a settlement pattern

that was typical of rural southern California at the time (
Figure
7 )
. The current alignments of Baseline Road and some o
f the intersecting streets across the
project area dated to that period.

Between the 1890s and the 1940s, a few
buildings,

presumably

farmsteads,
were noted along the segment of Baseline Road in the project area, but most of the land was used as agricultu
ral fields, including citrus groves or other types of orchards (Figure 8; NETR Online 1938;

1948).

In the early days of

the post
-
Wo
rld War II boom, the number of building
along

the project
route

began to
rise
, but the rural character of the area did not change until the 1966 -
1980 era, when the
first suburban residential tract developments occurred on the south side of Baseline Road (F igure 9;
NETR
Online 19
48 -
1980).

Figure
9 ; NETR Online 1948
-

)
.

The retention basins adjacent to the project area today, namely Cactus Basins No. 3 and No. 3A, were
built sometime between 1980 and 1994
, after the quarry ceased operation

(
NETR Online
1980;
1994
)
.

By
the mid
-
19 9
0s
, most of the land along the south side of Baseline Road had been developed into residential neighborhoods

(
NETR Online
1994; Google Earth 1994; 1995). The final inf
ill
development, along Grove Place between Maple Avenue and Locus Avenue, was completed

between 2005 and 2009 (Google Earth 2002
-
2009).

On the north side of Baseline Road, the rural
land uses persisted

well

into the 1990s before the construction of two se
lf
-
storage facilities near the
eastern end of the project area began to transform the l andscape, followed by two
strip malls

at the
intersection of Ayala Road in 2004
-
2005 (Google Earth 1994
-
2005).

The large warehouses that dominate the land use on that

side of Baseline Road
is the most recent
development along the project route, dating o
nly to 2013
-
2018 (Google Earth 2005
-
2018).

With the
accelerated residential and commercial development along its course

since the 1980s,
the character
and configuration

of Baseline Road
itself
have
also
been significantly altered, most notably with the
ad
dition of curbs, sidewalks and,
during

the current decade, landscaped medians (

NATIVE AMERICAN

CONSULTATION

In
response to CRM TECH’s
request
, the NAHC

reported in
a letter dated March 26, 2019, that the
s
acred
Lands Record
File

indicated the

presence of
Native American cultural resource
(
s
)

in the
project
vicinity
but

referred further
inqui
ries

the Gabrieleño Band of Mission Indians
–
Kizh
Nation.

In the meantime, the
NAHC
also recommend
ed

that other loca
l Native American groups be
contacted for further information

and

provided a list of potential contacts in th
e region (see
App
endix

2).

Upon receiving the NAHC
’s reply
,

CRM TECH
sent written requests for comments to
all nine tribal
organizations on the
referral list

(see
Appendix 2
)
. For some of th
e tribes, the designated
spokespersons on

cultural resources

issues were contacted

i
n lieu of
the tribal political leaders

on
the
referral list, as recommended in the past by

the per
tinent

tribal government st
aff
.

The
nine
tribal
representatives contacted

during this s
tudy are listed below:

•

Andy Salas, Chairperson
,

Gabrieleño Band of Mission Indians
–
Kizh Nation
;

•

Sandonne Goad, Chairperson
,

Gabrielino/Tongva Nation
;

;

•

Mark Cochrane, Chairperson, Serrano Nation of Mission Indians .

A
s of this
time, three of the nine
tribes

hav
e responded
in writing (
see
Appendix 2
)
.

Travis
Armstrong

of the
Morongo Band

and
Jessica Mauck

of the
San Manuel Band

stated that the
ir

respective
tribe
s

ha
ve

no
additional
information to provide
for

this st
udy
. Ms. Mauck
indicated
that
the San Manuel B
and
“
is unlikely to have concerns during formal consultation with the lead
agency
,
” while Mr.

A
rmstrong
indicated

that the
Morongo Band

“
may provide other information to
the lead agency during the AB 52 consultation process
.
”

On behalf of the
Gabrieleño

Band of Mission Indians
–
Kizh Nation
,
Brandy Salas
, Tribal
Admin
istrative

Specialist
, replied that
t
he tribe
would like

to
pursue
government
-
to
-
government
consultation with the
City of Rialto.

She did not, however, provide any
f
urther information o
n
Nativ
e American cultural resource
(
s
)

that may
exist

in the project
vicinity
.

FIELD SURVEY

The results of the
field
survey
indicate

that
all
four

of the

historical/archaeological
sites previously
recorded
on prope
rties

adjacent to

the project area

(
36 -
010659
,

36 -
010908
,

36 -
021612
,

and 36
-
029057
)

have been removed
.

Their former locations are now occupied by the residential neighborhood along Grove Place and
the wareh
o
uses
between Maple Avenue and Laurel Avenue,
which

were built in 2005
-
2009 and 2013
-
2018, respectively (Google Earth 2005
-
2018).

Baseline Road,
the
physical embo
d
iment
of Site
36 -
015497

(
San Bernardino Baseline
)
, remains in
heavy
use
today
as a
local

thoroughfare
.

As a result of
continuous alterations
in r
esponse to
the
gradual urb
aniza
tion
of the area
along its course, th
is segment of the road is now
entirely modern
in
appearance

and demonstrate
s

no historical characteristics despite its 19th century origin

(Figure 4)
.

No other poten
tial
“
historical resources
”

were encountered within the project a
rea throughout the
course of the survey.

DISCUSSION

The purpose of this study is to identify any cultural resources wit hin or adjacent to the project area
and assist the City of Rialto in determining whether such resources meet the official definition of
“historical resources” or as provided in the California Public Resources Code, in particular CEQA.

According to PRC §50

20.1(j), “‘historical resource’ includes, but is not limited to, any object, building, site, area, place, record, or manuscript which

is historically or archaeologically significant,
or is significant in the architectural, engineering, scientific, economic , agricultural, educational,
social, political, military, or cultural annals of California.”

specifically, CEQA guidelines state that the term
“
historical resources
”

applies to any
properties
listed in or determined to be eligible for listing in the California Register of

H
istorical
Resources, included in a local register of historical resources,

or determined to be historically
significant by the
l
ead
a
gency (Title 14 CCR §15064.5(a)(1)
-
(3)).

In other words, buildings,
structures, sites, or districts that belong to one or more of the following three categories are to be considered
“
historical re
sources
”

for the purposes of CEQA compliance (160 Cal. App. 4th 1051):

•

Mandatory historical resources: properties that are listed in or formally determined to be eligible for listing in the California Register of Historical Resources;

•

Presumptive historic
al resources: properties that are designated in an officially established local register, recognized by local ordinance, resolution, or general plan, or identified in a local survey prepared in accordance with PRC §5024.1(g), unless determined not to be hi storically or
culturally significant by the lead agency upon a preponderance of the evidence;

•

Discretionary historical resources: properties that are determined to be historically significant in the lead agency
’
s discretion, independent of any decision to
list or designate them in a national,
state, or local register of historical resources.

In summary of the research results presented

above,
five

historical/archaeological sites were
previously recorded within or adjacent to the project area , but four of them
,
36 -
010659
,

36 -
010908
,

36 -
021612
,

and 36
-
029057
,

are no longer extant today
.

The remaining site,
36 -
015497
, represents
the
San Bernardino B
aseline
, which is
embodied by Baseline Road in the project vicinity
. As a part
of the basis for
all land surveys and titles in southern California since

1853, the
San Bernardino
Baseline
h
as
been
designated a California Point of Historical Interest (CPHI -
SBr
-
12)
.

As
a property
included in a state
-
wide
register of
local
historical resources
,

Site
36 -
015497
clearly
meets the
definition of a “historical resource”
in the category of
“
p
resumptive

historical resour
ces
.
”

The historic value of
Site
36 -
015497, however, is symbolic in nature and is derived from the conceptual line across the landscape instead of th
e existing roadway
. The

current configuration and
physical features of
Baseline Road
, which are
modern
and in fact quite recent
in
origin,

do not
contribute to the historic significance of the site.

Since

Site
36 -
0 15497

exists in the project area
largely on paper only
,

CRM TECH

concludes that the proposed project has no potential to affect the

significance or integrity

of this “historical resource.”

n
o other
potential
“
historical resources
”

were
identified

within the project area
,

CRM TECH
further
concludes that no “historical resources”
will be impacted by

the
project.

CONCLUSION AND RECOM

MENDATIONS

CEQA establishes that a project that may cause a substantial adverse change in the significance of a “historical resource” or
a “tribal cultural resource”

is a project that may have a significant effect on
the environment

(PRC §21084.1
-
2)
.
“
Substantial adverse change,
”

according to PRC §5020.1(q),
“
means demolition, destruction, relocation, or alteration such that the significance of a historical resource would be impaired.
”

As stated above, the results of the present study indicate that no “historical resources” will be
impacted by

the
proposed
project
.

However,

the NAHC

reported the presence of unspecified Native
American cultural resource(s) in the project
vicinity

and

referred further
inquiries

the Gabrieleño
Band of Mission Indians
–
Kizh Nation
,
who

did not provide any
information on such resources

during this study
. A
ccord
ing to

CEQA guidelines, the identification of potential “tribal cultural resources” is beyond the scope of this study and ne
eds to be addressed through government
-
to
-
government consultations

between the City of Rialto and the pertinent Native American groups pursuant to Assembly Bill 52.

Based on these findings, CRM TECH presents the following recommendations to the City of Rialto:

•

A
preliminary
conclusio
n

of
No Impact

cultural resources appears to be appropriate for this
project,
pending the completion of
the City
’
s
government
-
to
-
government

consultation

process

with
local
Native American

tribes

to ensure the proper identification of potential “t
ribal cultural
resources.”

•

No additional cultural resources investigation will be necessary for the project unless construction plans undergo such changes as to include areas not covered by this study.

•

If buried cultural materials are
encountered inadvertently during any e
arth
-
moving operations
associated with the project, all work within 50 feet of the discovery should be halted or diverted until a qualified archaeologist can evaluate the nature and significance of the finds .

indicate
s

the presence of
Native American cultural
resources in the project area and recommends th
at the

San Bernardino County, California

CRM TECH Contract #3454

Dear
Ms.

Goad
:

I am writing to bring your attention to an ongoing CEQA -
compliance study for the proposed project
referenced above. The project entails the installation of approx imat
ely 2.25 linear miles of new
storm drain pipeline from the existing Cactus Basin
s

south to Baseline Road

and

then
we
st within
the
Baseline Road
right
-

way to Tamarind Avenue. The accompanying map, based on USGS Devore and Fontana, Calif., 7.5' quadrangl
es, depicts the location of the project area in Sections 32 -
34, T1N R5W
,

and Sections 3
-
5, T1S R5W, SBBM.

Records on file at the South Central Coastal Information Center (SCCIC) report that Baseline Road (Site 36
-
015497) is the only known historical/archa
eological site in the project area. However, the
Native American Heritage Commission
Sacred Lands

s

the presence of
Native
American cultural resources in the project area
, and
the commission
recommends that the Gabrieleno
Band of Mission Indi
ans
-

Kizh Nation and other local tribes be contacted for further information (see attached). Therefore, a
s part of the cultural resources study for this project, I am writing to request your input on potential Native American cultural resources in or nea r the project area.

Please respond at your earliest convenience if you have any specific knowledge of sacr ed/religious
sites or other sites of Native American traditional cultural value in or near the project area, or any other information to consider dur
ing the cultural resources investigations. Any information or concerns may be forwarded to CRM TECH by tel
ephone, e
-
mail, facsimile, or standard mail.

Requests for documentation or information we cannot provide will be forwarded to our client and/or the
lead agency, namely the City of Rialto.

We would also like to clarify that, as the cultural resources cons ultant for the project, CRM TECH is
not involved in the AB 52
-
compliance process or in government
-
to
-
government consultations. The
purpose of this l
etter is to seek any information that you may have to help us determine if there are cultural resources in
or near the project area that we should be aware of and to help us assess the sensitivity of the project area. Thank you for your time and effort in

addressing this important
matter.

Hi Nina,

Thank you for contacting the San Manuel Band of Mission Indians (SMBMI) regarding the above referenced project. SMBMI appreciates the opportunity to re view the project documentation, which
was received by our Cultural Resourc
es Management Department on 28 March 2019. While SMBMI
consults on projects within the City of Rialto, this particular area has not historically been of major concern. Additionally,
based on recent information obtained by the Tribe, I am going to start pul ling
back on the nearby areas for which SMBMI previously expressed concern. As such, SMBMI does not have information to provide for the study and is unlikely to have concerns during formal
consultation with the lead agency.

Thank you,

Jessica Mauck

y shall occur within
the 300-foot or 500-foot buffer until the young hav
e fledged the nest,
as confirmed by a qualified biologist.

Construction shall occur outside of the nesting
season or a copy of the field survey docu-
