Paleontological Resources Assessment for the Slauson Avenue and Atlantic Boulevard Congestion Relief Improvements Project, Los Angeles County, California Project Number: 2042639600 iv
Executive Summary
Stantec Consulting Services Inc. (Stantec) conducted a paleontological resources assessment on behalf of the City of Maywood for the Slauson Avenue and Atlantic Boulevard Congestion Relief Improvements Project (the Project) on portions of an approximately one-mile corridor of Slauson Avenue in Maywood, Los Angeles County, California. This paleontological study was conducted in support of the proposed roadway improvements and widening for the intersection of Slauson Avenue and Atlantic Boulevard.

The proposed Project is subject to compliance with the California Environmental Quality Act (CEQA) requirements regarding the Project's potential impacts on paleontological resources. The lead agency for this Project is the City of Maywood. As part of CEQA compliance, a paleontological resources assessment was conducted to assess potential impacts of the proposed Project on paleontological resources.

This paleontological resources assessment consisted of an analysis of existing data including a museum records search from the Natural History Museum of Los Angeles County and a review of the most recent geologic mapping, relevant scientific literature, and the online collections of the University of California Museum of Paleontology. This research was used to assign paleontological potential rankings of the Society of Vertebrate Paleontology (2010) to the geologic units present in the Project area, either at the surface or in the subsurface. Following this, Project plans were reviewed to identify any potential impacts to paleontological resources and develop appropriate mitigation recommendations to reduce potential impacts to less than significant.

The results of this study indicate that one geologic unit is likely present in the Project area: alluvium, which is assessed as having low-to-high paleontological potential, increasing with depth. In order to avoid impacts to paleontological resources and satisfy CEQA requirements, Stantec recommends a qualified paleontologist meeting professional standards as defined by Murphey et al. (2019) be retained as the designated Project Paleontologist to oversee all aspects of paleontological mitigation. In order to avoid impacts to paleontological resources, Stantec recommends the following mitigation activities for the Project:

1. A paleontologist meeting professional standards as defined by Murphey et al. (2019) shall be retained as the Project Paleontologist to oversee all aspects of paleontological mitigation, including paleontological monitoring of earthwork and ground disturbing activities into undisturbed geologic units with high paleontological potential, to be conducted by a paleontological monitor meeting industry standards (Murphey et al. 2019). Within the Project area, older alluvium has high paleontological potential and is present at estimated depths of 10 feet below ground surface.

The paleontological monitoring program should include development of a Paleontological Resources Monitoring and Mitigation Plan that outlines where and when monitoring is necessary, onsite (full-time) paleontological monitoring of ground disturbance over 10 feet in depth, an unanticipated discoveries plan in the event that fossils are encountered, and final reporting.

2. The Project Paleontologist shall develop a Worker’s Environmental Awareness Program training that communicates requirements and procedures for the inadvertent discovery of paleontological resources during construction to be delivered by the paleontologist or their designated representative to the construction crew prior to the onset of ground disturbance.

3. In the event that paleontological resources are encountered during construction activities, all work must stop in the immediate vicinity of the finds while the paleontological monitor documents the find. The designated Project Paleontologist shall assess the find. Should the Project Paleontologist assess the find as significant, the find shall be collected and curated in an accredited repository along with all necessary associated data and curation fees.

Based on the findings in this study and the implementation of the above mitigation recommendations, the proposed Project should not cause an adverse impact to paleontological resources. Therefore, additional paleontological resource studies are not recommended or required at this time. Changes to the Project plans or Project area from those assessed in this study will require additional assessment for impacts to paleontological resources.

1 Introduction
Stantec Consulting Services Inc. (Stantec) conducted a paleontological resources assessment on behalf of the City of Maywood for the Slauson Avenue and Atlantic Boulevard Congestion Relief Improvements Project (the Project) on portions of an approximately one-mile corridor of Slauson Avenue in Maywood, Los Angeles County, California. This paleontological study was conducted in support of the proposed roadway improvements and widening for the intersection of Slauson Avenue and Atlantic Boulevard.

The proposed Project is subject to compliance with the California Environmental Quality Act (CEQA) requirements regarding the Project's potential impacts on paleontological resources. The lead agency for the Project is the City of Maywood. As part of CEQA compliance, a paleontological resources assessment was conducted to assess potential impacts of the proposed Project on paleontological resources.

1.1 Project Description
The Project will widen the Slauson Avenue and Atlantic Boulevard intersection to relieve congestion during both morning and evening peak hours, and to alleviate existing queuing conditions to accommodate projected traffic in the area. Construction and operational-related activities would be focused on the Slauson Avenue and Atlantic Boulevard intersection with the remaining project activities are associated with traffic signals and synchronization. Work at Slauson Avenue and Atlantic Boulevard will consist of surface grading for road widening and trenching for the relocation of utilities and other underground components of the roadway. Provided below is a description of the proposed improvements.

Roadway Widening
• Widening of the west and east legs of Slauson Avenue and south leg of Atlantic Boulevard to accommodate dual left turn lanes at the intersection in eastbound Slauson Avenue and northbound Atlantic Boulevard direction, as recommended in the I-710 CRP. • Reconstruct the curb returns at all four corners to accommodate current Caltrans Truck Turning Standards.
• Close the mid-block median opening along Slauson Avenue to provide a longer eastbound dual left turn storage pocket and eliminate the conflicting left turn movements to and from the Food4Less commercial center.
• Reduce the width of the existing median islands along the east and west legs of Slauson Avenue and north leg of Atlantic Boulevard and remove the existing median along the south leg of Atlantic Boulevard of the intersection to accommodate the dual left turn lanes. The existing landscaping/trees, utilities and City entry monument signs within these median islands would be removed or relocated.
• Grind and overlay with asphalt concrete pavement the existing concrete intersection / approaches and construct new decorative paver crosswalks.

The Project area is located in portions of Section 19 Township 20 South, Range 12 West, and Section 24 Township 20 South and Range 13 West as depicted on the South Gate, California United States Geological Survey 7.5-minute series topographic quadrangle (Figure 2).

1.3 Paleontological Resources
Fossils are any evidence of ancient life. This includes the remains of the body of an organism, such as bones, skin impressions, shell, or leaves, as well as traces of an organism’s activity, such as footprints or burrows, called trace fossils. In addition to the fossils themselves, geologic context is an important component of paleontological resources, and includes the stratigraphic placement of the fossil as well as the lithology of the rock in order to assess paleoecologic setting, depositional environment, and taphonomy. Fossils are protected by federal, state, and local regulations as nonrenewable natural resources.

While CEQA does not define a significance threshold for paleontological resources, the standards of the Society of Vertebrate Paleontology (SVP) (2010) are often used in the absence of a legal definition of significance. The SVP defines significant paleontological resources as:
identifiable vertebrate fossils, large or small, uncommon invertebrate, plant, and trace fossils, and other data that provide taphonomic, taxonomic, phylogenetic, paleoecologic, stratigraphic, and/or biochronologic information. Paleontological resources are considered to be older than recorded human history and/or older than middle Holocene (i.e., older than about 5,000 radiocarbon years). [SVP 2010: 11].

Furthermore, the Paleontological Resources Preservation Act (PRPA) defines paleontological resources as:

Any fossilized remains, traces, or imprints of organisms, preserved in or on the earth’s crust, that are of paleontological interest and that provide information about the history of life on earth, except that the term does not include— (A) any materials associated with an archaeological resource (as defined in section 3(1) of the Archaeological Resources Protection Act of 1979 (16 U.S.C. 470bb(1)); or (B) any cultural item (as defined in section 2 of the Native American Graves Protection and Repatriation Act (25 U.S.C. 3001)). [PRPA Sec. 6301] Using this definition, the concept of scientific importance, or significance, is included in the definition of paleontological resources; thus, not all fossils are considered to be paleontological resources under the PRPA.

It should be noted that the threshold for significance varies with factors including geologic unit, geographic area, and the current state of scientific research, and may also vary between different agencies (Murphey et al. 2019). Numerous paleontological studies have developed criteria for the assessment of significance for fossil discoveries (e.g., Eisentraut and Cooper 2002, Murphey et al. 2019, Murphey and Daitch 2007, Scott and Springer 2003). In general, these studies assess fossils as significant if one or more of the following criteria apply:

Paleontological Resources Assessment for the Slauson Avenue and Atlantic Boulevard Congestion Relief Improvements Project, Los Angeles County, California 1 Introduction
Project Number: 2042639600 8
• The fossils provide information on the evolutionary relationships and developmental trends among organisms, living or extinct.
• The fossils provide data useful in determining the age(s) of the rock unit or sedimentary stratum, including data important in determining the depositional history of the region and the timing of geologic events, through biochronology or biostratigraphy and the correlation with isotopic dating.
• The fossils provide ecological data, such as the development of biological communities, the interaction between paleobotanical and paleozoological biotas, or the biogeography of lineages.
• The fossils demonstrate unusual or spectacular circumstances in the history of life. • The fossils provide information on the preservational pathways of paleontological resources, including taphonomy, diagenesis, or preservational biases in the fossil record. • The fossils are in short supply and/or in danger of being depleted or destroyed by the elements, vandalism, or commercial exploitation, and are not found in other geographic locations. • The fossils inform our understanding of anthropogenic affects to global environments or climate.

A geologic unit known to contain significant paleontological resources is considered sensitive to adverse impacts if there is a high probability that earth-moving or ground-disturbing activities in that rock unit will either disturb or destroy fossil remains directly or indirectly. This definition of sensitivity differs fundamentally from the definition for archaeological resources as follows:

It is extremely important to distinguish between archaeological and paleontological (fossil) resource sites when defining the sensitivity of rock units. The boundaries of archaeological sites define the areal extent of the resource. Paleontological sites, however, indicate that the containing sedimentary rock unit or formation is fossiliferous. The limits of the entire rock formation, both areal and stratigraphic, therefore define the scope of the paleontological potential in each case. [SVP 2010: 2].

Many archaeological sites contain features that are visually detectable on the surface. In contrast, fossils are often contained within surficial sediments or bedrock and are therefore not observable or detectable unless exposed by erosion or human activity.

In summary, in the absence of observable paleontological resources on the surface, paleontologists must assess the potential of geologic units as a whole to yield paleontological resources based on their known potential to produce significant fossils elsewhere. Monitoring by experienced paleontologists greatly increases the probability that fossils will be discovered during ground-disturbing activities and that, if these remains are significant, successful mitigation and salvage efforts may be undertaken to prevent adverse impacts to these resources.

2.0 Regulatory Framework
Project Number: 2042639600 9

2.0 Regulatory Framework
California has enacted multiple laws and regulations that provide for the protection of paleontological resources. This investigation was conducted to meet these requirements regarding paleontological resources on the lands proposed for development.

2.1 State of California

2.1.1 CALIFORNIA ENVIRONMENTAL QUALITY ACT
CEQA (Public Resources Code [PRC] Sections 21000 et seq) requires that before approving most discretionary projects, the Lead Agency must identify and examine any significant adverse environmental effects that may result from activities associated with such projects. As updated in 2016, CEQA separates the consideration of paleontological resources from cultural resources (PRC Section 21083.09). The Appendix G checklist (Title 14, Division 6, Chapter 3, California Code of Regulations 15000 et seq.) requires an answer to the question, “Will the proposed project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?” Under these requirements, Stantec has conducted a paleontological resources assessment to determine impacts of the proposed project on paleontological resources within the Project area.

2.1.2 PUBLIC RESOURCES CODE
The California PRC (Chapter 1.7, Sections 5097 and 30244) includes additional state-level requirements for the assessment and management of paleontological resources. These statutes require reasonable mitigation of adverse impacts to paleontological resources resulting from development on state lands, define the removal of paleontological sites or features from state lands as a misdemeanor, and prohibit the removal of any paleontological site or feature from state land without permission of the applicable jurisdictional agency.

3.0 Professional Standards
The SVP (2010) and a number of scientific studies (Eisentraut and Cooper 2002; Murphey et al. 2019; Scott and Springer 2003) have developed guidelines for professional qualifications, conducting paleontological assessments, and developing mitigation measures for the protection of paleontological resources. These guidelines are broadly similar, and include the use of museum records searches, scientific literature reviews, and, in some cases, field surveys to assess the potential of an area to preserve paleontological resources. Should that potential be high, accepted mitigation measures include paleontological monitoring, data recordation of all fossils encountered, collection and curation of significant fossils and associated data, and in some cases screening of sediment for microfossils.

This study has been conducted in accordance with these guidelines and the recommendations provided herein meet these standards.

4.0 Geologic Setting
Project Number: 2042639600 10

4.0 Geologic Setting
The Project area is in the Los Angeles Basin, a structural depression approximately 50 miles long and 20 miles wide in the northernmost Peninsular Ranges Geomorphic Province (Ingersoll and Rumelhart 1999).

The Los Angeles basin developed as a result of tectonic forces and the San Andreas fault zone, with subsidence occurring 18 – 3 million years ago (Critelli et al. 1995). While sediments dating back to the Cretaceous (66 million years ago) are preserved in the basin, continuous sedimentation began in the middle Miocene (around 13 million years ago) and continues today, resulting in thousands of feet of accumulation (Yerkes et al. 1965). Most of these sediments are marine, until sea level dropped in the Pleistocene and deposition of the alluvial sediments that compose the uppermost units in the Los Angeles Basin began.

The Los Angeles Basin is subdivided into four structural blocks, with the Project area occurring in the Central Block, where sediments range from 32,000 to 35,000 feet thick (Yerkes et al. 1965). The Central Block is wedge-shaped, extending from the Santa Monica Mountains in the northwest, where it is about 10 miles wide, to the San Joaquin Hills to the southeast, where it widens to around 20 miles across (Yerkes et al. 1965).

5.0 Methodology
The paleontological resource assessment reported herein consisted of an analysis of existing data incorporating a museum records search from the Natural History Museum of Los Angeles County (LACM) and a review of the scientific literature, geologic mapping, and the online database of the University of California Museum of Paleontology (UCMP). The UCMP’s database does not provide specific geographic locations beyond the county the fossils were recovered from but does include locality names that can sometimes be used to infer the general area of the locality.

To assess if paleontological resources are likely to be encountered in any given area, the paleontological potential of the geologic units present in the area is assessed. Paleontological potential of a geologic unit consists of both (a) the potential for yielding abundant vertebrate fossils or for yielding significant fossils, large or small, vertebrate, invertebrate, plant, or trace fossils and (b) the importance of recovered evidence for new and significant taxonomic, phylogenetic, paleoecologic, taphonomic, biochronologic, or stratigraphic data (SVP 2010). Unlike archaeological resources that often have a limited aerial extent, paleontological resources may occur throughout a geologic unit, and so paleontological potential is assessed for the unit as a whole. Provided below is the methodology used during the current study to assess the potential of the Project to impact paleontological resources.

The paleontological assessment presented here was conducted by Stantec Principal Paleontologist Alyssa Bell, Ph.D. Geographic Information System (GIS) maps and figures were drafted by GIS Technician Danny Law, B.S. This report was authored by Paleontologist Matthew Cline, M.S., and peer reviewed by Principal Paleontologist Alyssa Bell, Ph.D. Stantec’s work in support of the Project was IJ

managed by Principal Mohammad Heiat, M.S., who coordinated all work and provided quality assurance and control.

5.1 Analysis of Existing Data
In order to assess the paleontological potential of the Project area, the most recent geologic mapping of the Project area and vicinity (Saucedo et al. 2003) was consulted to identify all geologic units present at the surface or likely present in the subsurface. A records search was obtained from the Natural History Museum of Los Angeles County (LACM) (Appendix A) and a review of the scientific literature was conducted to determine the history of each of the geologic units mapped as present at the surface or likely present in the subsurface of the Project area for preserving paleontological resources.

5.2 Paleontological Resources Assessment
The results of the desktop analysis were used to assign the paleontological potential rankings of the SVP (2010) to the geologic units likely present in the Project area. These rankings are designed to inform the development of appropriate mitigation measures for the protection of paleontological resources and are widely accepted as industry standards in paleontological mitigation (Murphey et al. 2019; Scott and Springer 2003). These rankings are as follows:

High Potential. Rock units from which vertebrate or significant invertebrate, plant, or trace fossils have been recovered are considered to have a high potential for containing additional significant paleontological resources. Rock units classified as having high potential for producing paleontological resources include, but are not limited to, sedimentary formations that are temporally or lithologically suitable for the preservation of fossils (e. g., middle Holocene and older, fine-grained fluvial sandstones, argillaceous and carbonate-rich paleosols, cross-bedded point bar sandstones, fine-grained marine sandstones, etc.), some volcaniclastic formations (e. g., ashes or tephras), and some low-grade metamorphic rocks.

Undetermined Potential. Rock units for which little information is available in the literature or museum records concerning their paleontological content, geologic age, and depositional environment are considered to have undetermined potential. Further study and field work is necessary to determine if these rock units have high or low potential to contain significant paleontological resources.

Low Potential. Rock units that are poorly represented by fossil specimens in institutional collections or, based on general scientific consensus, only preserve fossils in rare circumstances (e. g., basalt flows or Recent colluvium) have low paleontological potential.

No Potential. Some rock units have no potential to contain significant paleontological resources, for instance high-grade metamorphic rocks (such as gneisses and schists) and plutonic igneous rocks (such as granites and diorites).

Following the assessment of paleontological potential, an impacts assessment was conducted comparing planned Project activities in terms of locations, depths, and ground disturbance methods with mapped IJ

geologic units. Where potential adverse impacts from Project activities were identified, mitigation recommendations were developed to reduce those impacts to less than significant.

5.3 Paleontological Impacts Assessment
Impacts to paleontological resources can be classified as direct, indirect, or cumulative. Impacts can also be considered as adverse impacts or as positive impacts. Direct adverse impacts on paleontological resources are the result of damage or destruction of these nonrenewable resources by surface disturbing actions including construction excavations. Therefore, in areas that contain paleontologically sensitive geologic units, ground disturbance has the potential to adversely impact paleontological resources, by damaging or destroying them and rendering them permanently unavailable to science and society.

Positive direct impacts, however, may result when paleontological resources are identified during construction and the appropriately documented and salvaged, thus ensuring the specimens are protected for future study and education.

Indirect impacts typically include those effects which result from the continuing implementation of management decisions and resulting activities, including normal ongoing operations of facilities constructed within a given project area. They also occur as the result of the construction of new roads and trails in areas that were previously less accessible. This increases public access and therefore increases the likelihood of the loss of paleontological resources through vandalism and unlawful collecting, thus constituting an adverse indirect impact. Human activities that increase erosion also cause indirect impacts to surface and subsurface fossils as the result of exposure, transport, weathering, and reburial.

Cumulative adverse impacts can result from incrementally minor but collectively significant actions taking place over time. The incremental loss of paleontological resources over time from construction-related surface disturbance or vandalism and unlawful collection would represent a significant cumulative adverse impact, because it would result in the destruction of non-renewable paleontological resources and the associated irretrievable loss of scientific information.

The impact assessment conducted here takes into consideration all planned project activities in terms of aerial and subsurface extents, including the possibility of subsurface geologic units having a different paleontological potential than surficial units. For example, younger surficial sediments (alluvium, lacustrine, eolian, etc.) have low potential to preserve paleontological resources due to their age; yet sediments increase in age with depth and so these surficial deposits often overly older units that have high paleontological potential. In areas with this underlying geologic setting surficial work may be of low risk for impacting paleontological resources while activities that require excavations below the depth of the surficial deposits would be at greater risk of impacting paleontological resources. For this reason, the impact assessment takes into consideration both the surface and subsurface geology and is tailored to Project activities.

6.1 Project Area Geology and Paleontology
Geologic mapping by Saucedo et al. (2003) indicates the surface of the Project area consists of one geologic unit: alluvium (Figure 3). This geologic unit ranges in age from the Recent to the Holocene (roughly 11,700 years ago) and is described below.

Alluvium (Qal in Figure 3). Alluvial sediments are found across the surface of the Project area. These sediments consist of poorly consolidated and poorly sorted clay, sand, gravel and cobble alluvial fan and valley deposits (Saucedo et al. 2003). These sediments are relatively young in age, dating from the Recent to the early Holocene, and are likely underlain by older Pleistocene aged sediments at undetermined depths. While at the surface these sediments are too young to preserve fossils (under 5,000 years, as per the SVP [2010]), they increase in age with depth such that in the subsurface they are over 5,000 years old and may preserve fossils.

A paleontological records search was requested from the LACM on August 17, 2023, with the results delivered to Stantec on Augusts 20, 2023. The results indicate six fossil localities reported in unnamed Pleistocene aged sediments are within 10 miles of the Project area (Table 1). These fossil localities were discovered at depths as shallow of 15 feet below ground surface. Some of the recorded localities did not have a depth recorded. A search of the UCMP’s database indicate over 200 fossil localities are recorded within Los Angeles County in unnamed Pleistocene aged sediments.

A review of the scientific literature further establishes the types of fossils known from similar early Holocene and Pleistocene sediments in the region. These fossils represent a rich Ice Age fauna, including include animals found in North America today, such as deer, bison, sheep, and horses, as well as creatures no longer found in North America, such as camels, lions, cheetahs, and sloths, and extinct creatures such as mammoths, dire wolves, and saber-toothed cats (Jefferson 1989, 1991a, 1991b; Graham and Lundelius 1994; McDonald and Jefferson 2008; Reynolds and Reynolds 1991). In addition to these iconic large animals, a wide variety of small animals can be preserved, including reptiles such as frogs, salamanders, snakes, and birds (Jones et al. 2008, Springer et al. 2009, Reynolds 1989). These fossils are important for recreating the history of Southern California, in particular studying climate change (e.g., Roy et al. 1996, Trayler et al. 2015), extinction (e.g., Barnosky et al. 2004, Jones et al. 2008, Sandom et al. 2014, Scott 2010), and paleoecology (e.g., Connin et al. 1998).

6.2 Paleontological Potential of Geologic Units in the Project Area In order to assess the potential of the geologic units present at the surface or in the subsurface to preserve paleontological resources, Stantec conducted an analysis of existing data, as described above.

These investigations were used to assign the paleontological potential rankings of the SVP (2010) to the geologic units present at the Project area, both at the surface and in the subsurface. The results of this assessment are described below.

Alluvium (Qal in Figure 3). The alluvial sediments present in the Project area date to the Holocene, which ranges from the present to 11,700 years old. As defined by the SVP (2010), paleontological resources must be over 5,000 years in age, corresponding to the middle part of the Holocene. Therefore, the alluvial sediments in the Project area are too young at the surface to preserve paleontological resources, but increase in age with depth, such that they may preserve fossils in the subsurface. The review of scientific literature and records search performed by the LACM (2023) documents fossils in other unnamed Holocene-to-Pleistocene units from nearby locations at depths as shallow as15 feet below ground surface. Therefore, areas mapped as alluvium should be considered to have low-to-high paleontological potential, increasing with depth. The exact depth at which this transition occurs is unknown but estimated to be around 10 feet below ground surface, based on documented fossil localities in the Los Angeles Basin.

7.0 Recommendations and Management Considerations
Project Number: 2042639600 16

6.3 Potential Impacts to Paleontological Resources from Project Activities
The Project plans to a variety of improvements to the Slauson Avenue and Atlantic Boulevard intersection. This will entail ground disturbance consisting of surface grading for road widening and trenching for the relocation of utilities and other underground components of the roadway. The exact depths of this disturbance are unknown. Should ground disturbance exceed 10 feet in depth, it risks impacting early Holocene or older alluvial sediments with high paleontological potential.

Should paleontological resources be encountered during construction, their damage or destruction would constitute a direct adverse impact. Therefore, Stantec has developed recommendations for mitigation that will avoid damage or destruction of paleontological resources in the Project area, thus reducing direct adverse impacts to less than significant. It is not anticipated that the Project will pose indirect or cumulative adverse impacts to paleontological resources, as the final Project will not entail increased exposure or erosion of native sediments beyond the duration of the ground disturbance described above.

7.0 Recommendations and Management Considerations
The paleontological resources assessment described herein conducted an analysis of existing data, consisting of a records search from the LACM and a review of geologic mapping, the scientific literature, and the online collections of the UCMP, to assess the potential of the geologic units in the Project area to preserve paleontological resources. The results of this assessment show that geologic units with high paleontological potential are likely present in the subsurface at estimated depths of greater than 10 feet throughout the Project area.

Project activities may include surface grading and trenching for the relocation of utilities. Should Projectrelated activities encounter paleontological resources, the damage or destruction of those resources would constitute an adverse impact under CEQA. In order to avoid impacts to paleontological resources, Stantec recommends a qualified paleontologist meeting professional standards as defined by Murphey et al. (2019) be retained as the designated Project Paleontologist to oversee all aspects of paleontological mitigation. In order to avoid impacts to paleontological resources, Stantec recommends the following mitigation activities for the Project:

1. A paleontologist meeting professional standards as defined by Murphey et al. (2019) shall be retained as the Project Paleontologist to oversee all aspects of paleontological mitigation, including paleontological monitoring of earthwork and ground disturbing activities into undisturbed geologic units with high paleontological potential, to be conducted by a paleontological monitor meeting industry standards (Murphey et al. 2019). Within the Project area, older alluvium has high paleontological potential and is present at estimated depths of 10 feet below ground surface.

The paleontological monitoring program should include development of a Paleontological Resources Monitoring and Mitigation Plan that outlines where and when monitoring is necessary, IJ

Project Number: 2042639600 17
onsite (full-time) paleontological monitoring of ground disturbance over 10 feet in depth, an unanticipated discoveries plan in the event that fossils are encountered, and final reporting.

2. The Project Paleontologist shall develop a Worker’s Environmental Awareness Program training that communicates requirements and procedures for the inadvertent discovery of paleontological resources during construction to be delivered by the paleontologist or their designated representative to the construction crew prior to the onset of ground disturbance.

3. In the event that paleontological resources are encountered during construction activities, all work must stop in the immediate vicinity of the finds while the paleontological monitor documents the find. The designated Project Paleontologist shall assess the find. Should the Project Paleontologist assess the find as significant, the find shall be collected and curated in an accredited repository along with all necessary associated data and curation fees.

Based on the findings in this study and the implementation of the above mitigation recommendations, the proposed Project should not cause an adverse impact to paleontological resources. Therefore, no additional paleontological resource studies are recommended or required at this time. Changes to the Project plans or Project area from those assessed in this study will require additional assessment for impacts to paleontological resources.

EXECUTIVE SUMMARY
TC7369670.2s EXECUTIVE SUMMARY 10
Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

STANDARD ENVIRONMENTAL RECORDS
Lists of Federal NPL (Superfund) sites
NPL: Also known as Superfund, the National Priority List database is a subset of CERCLIS and identifies over 1,200 sites for priority cleanup under the Superfund program. The source of this database is the U.S. EPA.

A review of the NPL list, as provided by EDR, and dated 04/26/2023 has revealed that there is 1 NPL site within approximately 1 mile of the target property.

Lists of Federal CERCLA sites with NFRAP
SEMS-ARCHIVE: SEMS-ARCHIVE (Superfund Enterprise Management System Archive) tracks sites that have no further interest under the Federal Superfund Program based on available information. The list was formerly known as the CERCLIS-NFRAP, renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while it is archived if site conditions change and/or new information becomes available. Archived sites have been removed and archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA’s knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list the site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. The decision does not necessarily mean that there is no hazard associated with a given site; it only means that. based upon available information, the location is not judged to be potential NPL site.

A review of the SEMS-ARCHIVE list, as provided by EDR, and dated 04/26/2023 has revealed that there are 2 SEMS-ARCHIVE sites within approximately 0.5 miles of the target property.

ENVIROSTOR: The Department of Toxic Substances Control’s (DTSC’s) Site Mitigation and Brownfields Reuse Program’s (SMBRP’s) EnviroStor database identifes sites that have known contamination or sites for which there may be reasons to investigate further. The database includes the following site types: Federal Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information that was available in CalSites, and provides additional site information, including, but not limited to, identification of formerly-contaminated properties that have been released for reuse, properties where environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk characterization information that is used to assess potential impacts to public health and the environment at contaminated sites.

A review of the ENVIROSTOR list, as provided by EDR, and dated 01/23/2023 has revealed that there are 37 ENVIROSTOR sites within approximately 1 mile of the target property.
