Aquatic Resources Delineation for Pioneer Baptist Church Project
1.0 INTRODUCTION
On behalf of Pioneer Baptist Church, ECORP Consulting, Inc. conducted an aquatic resources delineation
for the approximately 3.88-acre Pioneer Baptist Church Project (Study Area) located in Sacramento
County, California. The Study Area is located south of Cripple Creek Road, east of Auburn Boulevard, and
north of Watson Way (Figure 1. Study Area Location and Vicinity). The Study Area corresponds to a portion
of Section 23, Township 10 North, Range 6 East within the “Citrus Heights, California” 7.5-minute
quadrangle (U.S. Geological Survey [USGS] 1992). The approximate center of the Study Area is located at
38.708902° latitude and -121.289498° longitude within the Lower American Watershed (Natural Resources
Conservation Service [NRCS], USGS, and U.S. Environmental Protection Agency [USEPA] 2016). Driving
directions to the Study Area are included as Attachment A.
This report describes aquatic resources identified within the Study Area that may be regulated by the U.S.
Army Corps of Engineers (USACE) pursuant to Section 404 of the federal Clean Water Act (CWA). The
information presented in this report provides data required by the USACE Sacramento District’s Minimum
Standards for Acceptance of Aquatic Resources Delineation Reports (USACE 2016a). The aquatic resource
boundaries depicted in this report represent a calculated estimation of the jurisdictional area within the
Study Area and are subject to modification following the USACE verification process.
The purpose of this report is to provide adequate information to USACE for the issuance of a Preliminary
Jurisdictional Determination (PJD).
2.0 REGULATORY SETTING
2.1 Waters of the United States
This report describes aquatic resources, including wetlands, that may be regulated by USACE under
Section 404 and/or the Regional Water Quality Control Board (RWQCB) under Section 401 of the federal
CWA. The following sections define these regulations.
2.1.1 Wetlands
Wetlands are “those areas that are inundated or saturated by surface or groundwater at a frequency and
duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation
typically adapted for life in saturated soil conditions” (51 Federal Register [FR] 41250, Nov. 13, 1986, as
amended at 58 FR 45036, Aug. 25, 1993). Wetlands can be perennial or intermittent.
2.1.2 Other Waters
Other waters are nontidal, perennial, and intermittent watercourses and tributaries to such watercourses
(51 FR 41250, Nov. 13, 1986, as amended at 58 FR 45036, August 25, 1993). The limit of USACE jurisdiction
for nontidal watercourses (without adjacent wetlands) is defined in 33 Code of Federal Regulations (CFR)
328.4(c)(1) as the “ordinary high water mark” (OHWM). The OHWM is defined as the “line on the shore
established by the fluctuations of water and indicated by physical characteristics such as clear, natural line
impressed on the bank, shelving, changes in the character of soil, destruction of terrestrial vegetation, the

presence of litter and debris, or other appropriate means that consider the characteristics of the
surrounding areas” approximation of the lateral limit of USACE jurisdiction. The upstream limits of other
waters are defined as the point where the OHWM is no longer perceptible.
2.2 Clean Water Act
The USACE regulates discharge of dredged or fill material into Waters of the U.S. under Section 404 of the
CWA. “Discharges of fill material” is defined as the addition of fill material into Waters of the U.S.,
including, but not limited to the following: placement of fill necessary for the construction of any
structure, or impoundment requiring rock, sand, dirt, or other material for its construction; site-
development fills for recreational, industrial, commercial, residential, and other uses; causeways or road
fills; and fill for intake and outfall pipes, and subaqueous utility lines [33 CFR § 328.2(f)]. In addition,
Section 401 of the CWA (33 U.S. Code 1341) requires any applicant for a federal license or permit to
conduct any activity that may result in a discharge of a pollutant into Waters of the U.S. to obtain a
certification that the discharge will comply with the applicable effluent limitations and water quality
standards.
Substantial impacts to wetlands, over 0.5 acre of impact, may require an individual permit. Projects that
only minimally affect wetlands, less than 0.5 acre of impact, may meet the conditions of one of the
existing Nationwide Permits. A Water Quality Certification or waiver pursuant to Section 401 of the CWA is
required for Section 404 permit actions; this certification or waiver is issued by the RWQCB.
2.3 Jurisdictional Assessment
On April 21, 2020, the USEPA and the USACE published the Navigable Waters Protection Rule (NWPR) to
define “Waters of the United States” in the FR (USACE and USEPA 2020). With the NWPR, the agencies
streamlined the definition of “Waters of the United States” so that it includes four categories of
jurisdictional waters, provides clear exclusions for many water features that traditionally have not been
regulated, and defines terms in the regulatory text that have never been defined before. The NWPR
regulates Traditional Navigable Waters (TNW) and the core tributary systems that provide perennial or
intermittent flow into them.
The four categories of federally regulated waters are:
the territorial seas and TNW,
perennial and intermittent tributaries to those waters,
certain lakes, ponds, and impoundments, and
wetlands adjacent to jurisdictional waters.
The final rule also details 12 categories of exclusions, features that are not “waters of the United States,”
such as features that only contain water in direct response to rainfall (e.g., ephemeral features),
groundwater, many ditches, prior converted cropland, and waste treatment systems.
ECORP Consulting, Inc. June 2, 2021

Pioneer Baptist Church Project 2018-062.02
Aquatic Resources Delineation for Pioneer Baptist Church Project
The final rule clarifies key elements related to the scope of federal CWA jurisdiction, including the
following:
Providing clarity and consistency by removing the proposed separate categories for jurisdictional
ditches and impoundments.
Refining the proposed definition of “typical year,” which provides important regional and
temporal flexibility and ensures jurisdiction is being accurately determined in times that are not
too wet and not too dry.
Defining “adjacent wetlands” as wetlands that are meaningfully connected to other jurisdictional
waters, for example, by directly abutting or having regular surface water communication with
jurisdictional waters.
The NWPR is the second step in a two-step process to review and revise the definition of “waters of the
United States” consistent with the February 2017 Presidential Executive Order entitled “Restoring the Rule
of Law, Federalism, and Economic Growth by Reviewing the ‘Waters of the United States.’” This final rule
became effective on June 22, 2020 and has replaced the Step One Rule published in October 2019.
2.4 Porter-Cologne Water Quality Act
The RWQCB implements water quality regulations under the federal CWA and the Porter-Cologne Water
Quality Act. These regulations require compliance with the National Pollutant Discharge Elimination
System (NPDES), including compliance with the California Storm Water NPDES General Construction
Permit for discharges of storm water runoff associated with construction activities. General Construction
Permits for projects that disturb one or more acres of land require development and implementation of a
Storm Water Pollution Prevention Plan. Under the Porter-Cologne Water Quality Act, the RWQCB
regulates actions that would involve “discharging waste, or proposing to discharge waste, with any region
that could affect the water of the state” (Water Code 13260(a)). Waters of the State are defined as “any
surface water or groundwater, including saline waters, within the boundaries of the state” (Water Code
13050 (e)). The RWQCB regulates all such activities, as well as dredging, filling, or discharging materials
into Waters of the State, that are not regulated by the USACE due to a lack of connectivity with a
navigable water body. The RWQCB may require issuance of Waste Discharge Requirements for these
activities.
3.0 METHODS
This aquatic resources delineation was conducted in accordance with the Corps of Engineers Wetlands
Delineation Manual (Environmental Laboratory 1987) and the Regional Supplement to the Corps of
Engineers Wetland Delineation Manual: Arid West Region (Arid West Region Supplement) (USACE 2008a).
Non-wetland waters were identified in the field according to A Field Guide to the Identification of the
Ordinary High Water mark (OHWM) in the Arid West Region of the Western United States (USACE 2008b),
where applicable. The boundaries of aquatic resources were delineated through standard field methods
(e.g., paired sample set analyses) and aerial photograph interpretation. Field data were recorded on
Wetland Determination Data Forms – Arid West Region (Attachment B). A color aerial photograph

(1”=100’ scale; National Agriculture Imagery Program 2020) was used to assist with mapping and ground-
truthing. Munsell Soil Color Charts (Munsell Color 2009) and the Web Soil Survey (NRCS 2021a) were used
to aid in identifying hydric soils in the field. The Jepson eFlora (Jepson eFlora Project [eds.] 2021) was used
for plant nomenclature and identification.
Field surveys were conducted on April 7, 2021 by ECORP biologists Daniel Wong and Hannah Kang. The
biologists walked the entire approximately 3.88-acre Study Area to determine the location and extent of
aquatic resources within the Study Area. Paired locations were sampled to evaluate whether the
vegetation, hydrology, and soils data supported an aquatic resource determination. At each paired
location, one point was located within the estimated aquatic resource area, and the other point was
situated outside the limits of the estimated aquatic resource area. Additional non-paired locations were
sampled to document marginal areas that were determined not to be aquatic resources because they
lacked hydrophytic vegetation, hydric soils, and/or wetland hydrology. Aquatic resources within the Study
Area were recorded in the field using a post-processing capable Global Positioning System (GPS) unit with
sub-meter accuracy (e.g., Apple iPad, Collector for ArcGIS application with Juniper System Geode
submeter GPS unit with real-time correction).
This aquatic resource delineation was conducted in the spring, within the blooming season for most plant
species, and was conducted at an acceptable time of the year to observe wetland hydrology. During the
2020-2021 water year prior to the field survey (October 1, 2020 to April 5, 2021) approximately 7.73 inches
of precipitation were recorded at the Sacramento 5 ESE reporting station (National Oceanic and
Atmospheric Administration [NOAA] 2021a), approximately 13 miles southwest of the Study Area. The
most recent measurable precipitation event prior to the 2021 survey occurred on March 19, 2021,
resulting in 0.01 inch of rainfall (NOAA 2021a).
3.1 Routine Determinations for Wetlands
To be determined a wetland, the following three criteria must be met:
A majority of dominant vegetation species are wetland-associated species;
Hydrologic conditions exist that result in periods of flooding, ponding, or saturation during the
growing season; and
Hydric soils are present.
3.1.1 Vegetation
Hydrophytic vegetation is defined as the sum total of macrophytic plant life that occurs in areas where the
frequency and duration of inundation or soil saturation produce permanent or periodically saturated soils
of sufficient duration to exert a controlling influence on the plant species present (Environmental
Laboratory 1987). The definition of wetlands includes the phrase "a prevalence of vegetation typically
adapted for life in saturated soil conditions." Prevalent vegetation is characterized by the dominant plant
species comprising the plant community (Environmental Laboratory 1987). The dominance test is the
basic hydrophytic vegetation indicator and was applied at each sampling point location. The "50/20 rule"
ECORP Consulting, Inc. June 2, 2021

Pioneer Baptist Church Project 2018-062.02
Aquatic Resources Delineation for Pioneer Baptist Church Project
was used to select the dominant plant species from each stratum of the community. The rule states that
for each stratum in the plant community, dominant species are the most abundant plant species (when
ranked in descending order of coverage and cumulatively totaled) that immediately exceed 50 percent of
the total coverage for the stratum, plus any additional species that individually comprise 20 percent or
more of the total cover in the stratum (USACE 1992, 2008a).
Dominant plant species observed at each sampling point were then classified according to their indicator
status (probability of occurrence in wetlands; Table 1), National Wetland Plant List (USACE 2018). If the
majority (more than 50 percent) of the dominant vegetation on a site are classified as obligate (OBL),
facultative wetland (FACW), or facultative (FAC), the site was considered to be dominated by hydrophytic
vegetation.
Table 1. Classification of Wetland-Associated Plant Species1
Plant Species Classification Abbreviation Probability of Occurring in Wetland
Obligate OBL Almost always occur in wetlands
Facultative Wetland FACW Usually occur in wetlands, but may occur in non-wetlands
Facultative FAC Occur in wetlands and non-wetlands
Facultative Upland FACU Usually occur in non-wetlands, but may occur in wetlands
Upland UPL Almost never occur in wetlands
Plants That Are Not Listed N/L Does not occur in wetlands in any region.
(assumed upland species)
1Source: USACE 2018
In instances where indicators of hydric soil and wetland hydrology were present, but the plant community
failed the dominance test, the vegetation was re-evaluated using the Prevalence Index. The Prevalence
Index is a weighted-average wetland indicator status of all plant species in the sampling plot, where each
indicator status category is given a numeric code (OBL=1, FACW=2, FAC=3, FACU=4, and UPL=5) and
weighting is by abundance (percent cover). If the plant community failed the Prevalence Index, the
presence/absence of plant morphological adaptations to prolonged inundation or saturation in the root
zone was evaluated.
3.1.2 Soils
A hydric soil is defined as a soil that formed under conditions of saturation, flooding, or ponding long
enough during the growing season to develop anaerobic conditions in the upper part (NRCS 2003).
Indicators that a hydric soil is present include, but are not limited to, histosols, histic epipedon, hydrogen
sulfide, depleted below dark surface, sandy redox, loamy gleyed matrix, depleted matrix, redox dark
surface, redox depressions, and vernal pools.
At each sampling point a soil pit was excavated to the depth needed to document an indicator, to confirm
the absence of indicators, or until refusal at each sampling point. The soil was then examined for hydric
soil indicators. Soil colors were determined while the soil was moist using the Munsell Soil Color Charts
(Munsell Color 2009). Hydric soils are formed predominantly by the accumulation or loss of iron,
manganese, sulfur, or carbon compounds in a saturated and anaerobic environment. These processes
and the features in the soil that develop can be identified by looking at the color and texture of the soils.

3.1.3 Hydrology
Wetlands, by definition, are seasonally or perennially inundated or saturated at or near (within 12 inches
of) the soil surface. Primary indicators of wetland hydrology include, but are not limited to: visual
observation of saturated soils, visual observation of inundation, surface soil cracks, inundation visible on
aerial imagery, water-stained leaves, oxidized rhizospheres along living roots, aquatic invertebrates, water
marks (secondary indicator in riverine environments), drift lines (secondary indicator in riverine
environments), and sediment deposits (secondary indicator in riverine environments). The occurrence of
one primary indicator is sufficient to conclude that wetland hydrology is present. If no primary indicators
are observed, two or more secondary indicators are required to conclude wetland hydrology is present.
Secondary indicators include, but are not limited to drainage patterns, crayfish burrows, FAC-neutral test,
and shallow aquitard.
4.0 RESULTS
4.1 Existing Site Conditions
The Study Area is located within relatively flat terrain situated at an elevational range of approximately
133 to 145 feet above mean sea level in the Sacramento Valley Subregion of the Great Central Valley
floristic region of California (Baldwin et al. 2012). The average winter low temperature in the vicinity of the
Study Area is 41.5 degrees Fahrenheit (˚F) and the average summer high temperature is 91.2˚F. Average
annual precipitation is approximately 20.27 inches, which falls as rain (NOAA 2021b).
The Study Area is an urban parcel surrounded by a mix of residential and retail to the south and north,
and single-family residential to the east. Rusch Community Park is on the western side of Auburn
Boulevard, opposite the Project site. Cripple Creek bisects the Study Area from the east to the west.
Portions of the Study Area contain gravel lots located in the northern and southern section of the Study
Area. A storm drain is located in the northern gravel lot, which drains into Cripple Creek.
The majority of the Study Area is ruderal, a vegetation community dominated primarily by a mix of
nonnative forbs such as common dandelion (Taraxacum officinale), bur clover (Medicago polymorpha), and
red-stemmed filaree (Erodium cicutarium).
Riparian oak woodland also occurs in the Study Area along Cripple Creek. This vegetation community
consists of an intermittent to dense canopy of valley oak (Quercus lobata) and blue oak (Quercus
douglasii), with an understory of annual vegetation community dominated by slender wild oat (Avena
barbata) and foxtail barley (Hordeum murinum).
4.1.1 California Aquatic Resource Inventory
The California Aquatic Resource Inventory (CARI; San Francisco Estuary Institute [SFEI] 2017) is a statewide
map of surface waters and related habitats combining multiple national and regional datasets, including
the National Wetlands Inventory and the National Hydrography Dataset. CARI includes aquatic resource
features mapped using a variety of remote sensing and modeling techniques. As such, these aquatic
ECORP Consulting, Inc. June 2, 2021

Pioneer Baptist Church Project 2018-062.02Aquatic Resources Delineation for Pioneer Baptist Church Project
features may or may not exist as represented. In addition, CARI data varies in detail, accuracy, and age,
and is meant to be used as a tool to assist with an aquatic resource delineation but not as the only source
of information (SFEI 2017).
According to CARI (SFEI 2017), there are several aquatic features mapped within the Study Area (Figure 2.
California Aquatic Resource Inventory Features). These include stream features mapped as fluvial natural,
which roughly correspond to Cripple Creek mapped onsite.
4.1.2 Soils
According to the Web Soil Survey (NRCS 2021a), two soil units, or types, have been mapped within the
Study Area (Figure 3. Natural Resources Conservation Service Soil Types):
148 – Fiddyment-Orangevale-Urban land complex, 2 to 8 percent slopes
227 –Urban land
These soil units do not contain any listed hydric components (NRCS 2021b).
4.2 Aquatic Resources
A total of 0.247 acre of aquatic resources has been mapped within the Study Area (Table 3). The wetland
determination data forms are included in Attachment B. A discussion of the aquatic resources is presented
below, and the aquatic resources delineation map is presented on Figure 4. Aquatic Resources Delineation.
Representative site photographs are included as Attachment C. The USACE Operations and Maintenance

Creeks are linear features that exhibit a bed and bank, OHWM, and flow continuously throughout the
year. The perennial creek (Cripple Creek) mapped within the Study Area flows through the Study Area
from the east to west. Hydrophytic vegetation was present along the banks and channel of Cripple Creek
in areas of sediment accumulation that provide a substrate suitable for plant establishment and growth.
Dominant plant species observed within the OHWM of Cripple Creek include northern water plantain
(Alisma triviale) and tall flatsedge (Cyperus eragrostis). Sampling point 2 was collected within the OHWM
of Cripple Creek. The OHWM was delineated in the field based on the transition from hydrophytes to
upland species, presence of water marks, drift/debris deposits, drainage patterns, and sediment deposits.
5.0 JURISDICTIONAL ASSESSMENT
Per Regulatory Guidance Letter 16-01, an applicant may request a PJD “in order to move ahead
expeditiously to obtain a Corps permit authorization where the requestor determines that it is in his or her
best interest to do so ... even where initial indications are that the aquatic resources on a parcel may not be
jurisdictional” (USACE 2016b). The following information on connectivity of wetlands and other waters in
the Study Area to TNW is provided should an Approved Jurisdictional Determination be necessary.
Cripple Creek is a perennial tributary to the Sacramento River via Lower Steelhead Creek. The USACE
Sacramento District has identified the Sacramento River as a navigable water. Therefore, Cripple Creek is
jurisdictional according to the NWPR and subject to regulation under Section 404 of the CWA. In addition,
Cripple Creek would also fall under the RWQCB jurisdiction as Waters of the State.
6.0 CONCLUSION
A total of 0.247 acre of aquatic resources has been mapped within the Study Area. This acreage represents
a calculated estimation of the extent of aquatic resources within the Study Area, and is subject to
modification following USACE review and/or the verification process. The placement of dredged or fill
material into jurisdictional features would require a permit pursuant to Section 404 of the CWA and
certification or waiver in compliance with Section 401 of the CWA.
