1.0 General

1.1 Intent
These General Earthwork and Grading Specifications are for the grading and earthwork shown on the approved grading plan(s) and/or indicated in the geotechnical report(s). These Specifications are a part of the recommendations contained in the geotechnical report(s). In case of conflict, the specific recommendations in the geotechnical report shall supersede these more general Specifications. Observations of the earthwork by the project Geotechnical Consultant during the course of grading may result in new or revised recommendations that could supersede these specifications or the recommendations in the geotechnical report(s).

1.2 The Geotechnical Consultant of Record
Prior to commencement of work, the owner shall employ the Geotechnical Consultant of Record (Geotechnical Consultant). The Geotechnical Consultants shall be responsible for reviewing the approved geotechnical report(s) and accepting the adequacy of the preliminary geotechnical findings, conclusions, and recommendations prior to the commencement of the grading.

Prior to commencement of grading, the Geotechnical Consultant shall review the "work plan" prepared by the Earthwork Contractor (Contractor) and schedule sufficient personnel to perform the appropriate level of observation, mapping, and compaction testing.

During the grading and earthwork operations, the Geotechnical Consultant shall observe, map, and document the subsurface exposures to verify the geotechnical design assumptions. If the observed conditions are found to be significantly different than the interpreted assumptions during the design phase, the Geotechnical Consultant shall inform the owner, recommend appropriate changes in design to accommodate the observed conditions, and notify the review agency where required.

Subsurface areas to be geotechnically observed, mapped, elevations recorded, and/or tested include natural ground after it has been cleared for receiving fill but before fill is placed, bottoms of all "remedial removal" areas, all key bottoms, and benches made on sloping ground to receive fill.

The Geotechnical Consultant shall observe the moisture-conditioning and processing of the subgrade and fill materials and perform relative compaction testing of fill to determine the attained level of compaction.

The Geotechnical Consultant shall provide the test results to the owner LEIGHTON AND ASSOCIATES, INC.

General Earthwork and Grading Specifications
-2-
and the Contractor on a routine and frequent basis.

1.3 The Earthwork Contractor
The Earthwork Contractor (Contractor) shall be qualified, experienced, and knowledgeable in earthwork logistics, preparation and processing of ground to receive fill, moisture-conditioning and processing of fill, and compacting fill. The Contractor shall review and accept the plans, geotechnical report(s), and these Specifications prior to commencement of grading. The Contractor shall be solely responsible for performing the grading in accordance with the plans and specifications.

The Contractor shall prepare and submit to the owner and the Geotechnical Consultant a work plan that indicates the sequence of earthwork grading, the number of "spreads" of work and the estimated quantities of daily earthwork contemplated for the site prior to commencement of grading. The Contractor shall inform the owner and the Geotechnical Consultant of changes in work schedules and updates to the work plan at least 24 hours in advance of such changes so that appropriate observations and tests can be planned and accomplished.

The Contractor shall not assume that the Geotechnical Consultant is aware of all grading operations.

The Contractor shall have the sole responsibility to provide adequate equipment and methods to accomplish the earthwork in accordance with the applicable grading codes and agency ordinances, these Specifications, and the recommendations in the approved geotechnical report(s) and grading plan(s). If, in the opinion of the Geotechnical Consultant, unsatisfactory conditions, such as unsuitable soil, improper moisture condition, inadequate compaction, insufficient buttress key size, adverse weather, etc., are resulting in a quality of work less than required in these specifications, the Geotechnical Consultant shall reject the work and may recommend to the owner that construction be stopped until the conditions are rectified.

2.0 Preparation of Areas to be Filled

2.1 Clearing and Grubbing
Vegetation, such as brush, grass, roots, and other deleterious material shall be sufficiently removed and properly disposed of in a method acceptable to the owner, governing agencies, and the Geotechnical Consultant.

LEIGHTON AND ASSOCIATES, INC.

General Earthwork and Grading Specifications
-3-
The Geotechnical Consultant shall evaluate the extent of these removals depending on specific site conditions. Earth fill material shall not contain more than 1 percent of organic materials (by volume). No fill lift shall contain more than 5 percent of organic matter. Nesting of the organic materials shall not be allowed.

If potentially hazardous materials are encountered, the Contractor shall stop work in the affected area, and a hazardous material specialist shall be informed immediately for proper evaluation and handling of these materials prior to continuing to work in that area.

As presently defined by the State of California, most refined petroleum products (gasoline, diesel fuel, motor oil, grease, coolant, etc.) have chemical constituents that are considered to be hazardous waste. As such, the indiscriminate dumping or spillage of these fluids onto the ground may constitute a misdemeanor, punishable by fines and/or imprisonment, and shall not be allowed.

2.2 Processing
Existing ground that has been declared satisfactory for support of fill by the Geotechnical Consultant shall be scarified to a minimum depth of 6 inches. Existing ground that is not satisfactory shall be overexcavated as specified in the following section. Scarification shall continue until soils are broken down and free of large clay lumps or clods and the working surface is reasonably uniform, flat, and free of uneven features that would inhibit uniform compaction.

2.3 Overexcavation
In addition to removals and overexcavations recommended in the approved geotechnical report(s) and the grading plan, soft, loose, dry, saturated, spongy, organic-rich, highly fractured or otherwise unsuitable ground shall be overexcavated to competent ground as evaluated by the Geotechnical Consultant during grading.

LEIGHTON AND ASSOCIATES, INC.

General Earthwork and Grading Specifications
-4-

2.4 Benching
Where fills are to be placed on ground with slopes steeper than 5:1 (horizontal to vertical units), the ground shall be stepped or benched. The lowest bench or key shall be a minimum of 15 feet wide and at least 2 feet deep, into competent material as evaluated by the Geotechnical Consultant. Other benches shall be excavated a minimum height of 4 feet into competent material or as otherwise recommended by the Geotechnical Consultant. Fill placed on ground sloping flatter than 5:1 shall also be benched or otherwise overexcavated to provide a flat subgrade for the fill.

2.5 Evaluation/Acceptance of Fill Areas
All areas to receive fill, including removal and processed areas, key bottoms, and benches, shall be observed, mapped, elevations recorded, and/or tested prior to being accepted by the Geotechnical Consultant as suitable to receive fill. The Contractor shall obtain a written acceptance from the Geotechnical Consultant prior to fill placement. A licensed surveyor shall provide the survey control for determining elevations of processed areas, keys, and benches.

3.0 Fill Material

3.1 General
Material to be used as fill shall be essentially free of organic matter and other deleterious substances evaluated and accepted by the Geotechnical Consultant prior to placement. Soils of poor quality, such as those with unacceptable gradation, high expansion potential, or low strength shall be placed in areas acceptable to the Geotechnical Consultant or mixed with other soils to achieve satisfactory fill material.

3.2 Oversize
Oversize material defined as rock, or other irreducible material with a maximum dimension greater than 8 inches, shall not be buried or placed in fill unless location, materials, and placement methods are specifically accepted by the Geotechnical Consultant. Placement operations shall be such that nesting of oversized material does not occur and such that oversize material is completely surrounded by compacted or densified fill.

Oversize material shall not be placed within 10 vertical feet of finish grade or within 2 feet of future utilities or underground construction.

3.3 Import
LEIGHTON AND ASSOCIATES, INC.

General Earthwork and Grading Specifications
-5-
If importing of fill material is required for grading, proposed import material shall meet the requirements of Section 3.1. The potential import source shall be given to the Geotechnical Consultant at least 48 hours (2 working days) before importing begins so that its suitability can be determined and appropriate tests performed.

4.0 Fill Placement and Compaction

4.1 Fill Layers
Approved fill material shall be placed in areas prepared to receive fill (per Section 3.0) in near-horizontal layers not exceeding 8 inches in loose thickness. The Geotechnical Consultant may accept thicker layers if testing indicates the grading procedures can adequately compact the thicker layers. Each layer shall be spread evenly and mixed thoroughly to attain relative uniformity of material and moisture throughout.

LEIGHTON AND ASSOCIATES, INC.

General Earthwork and Grading Specifications
-6-

4.2 Fill Moisture Conditioning
Fill soils shall be watered, dried back, blended, and/or mixed, as necessary to attain a relatively uniform moisture content at or slightly over optimum. Maximum density and optimum soil moisture content tests shall be performed in accordance with the American Society of Testing and Materials (ASTM Test Method D1557).

4.3 Compaction of Fill
After each layer has been moisture-conditioned, mixed, and evenly spread, it shall be uniformly compacted to not less than 90 percent of maximum dry density (ASTM Test Method D1557). Compaction equipment shall be adequately sized and be either specifically designed for soil compaction or of proven reliability to efficiently achieve the specified level of compaction with uniformity.

4.4 Compaction of Fill Slopes
In addition to normal compaction procedures specified above, compaction of slopes shall be accomplished by backrolling of slopes with sheepsfoot rollers at increments of 3 to 4 feet in fill elevation, or by other methods producing satisfactory results acceptable to the Geotechnical Consultant.

Upon completion of grading, relative compaction of the fill, out to the slope face, shall be at least 90 percent of maximum density per ASTM Test Method D1557.

4.5 Compaction Testing
Field-tests for moisture content and relative compaction of the fill soils shall be performed by the Geotechnical Consultant. Location and frequency of tests shall be at the Consultant's discretion based on field conditions encountered. Compaction test locations will not necessarily be selected on a random basis. Test locations shall be selected to verify adequacy of compaction levels in areas that are judged to be prone to inadequate compaction (such as close to slope faces and at the fill/bedrock benches).

4.6 Frequency of Compaction Testing
Tests shall be taken at intervals not exceeding 2 feet in vertical rise and/or 1,000 cubic yards of compacted fill soils embankment. In addition, as a guideline, at least one test shall be taken on slope faces for each 5,000 square feet of slope face and/or each 10 feet of vertical height of slope. The Contractor shall assure that fill construction is such that the LEIGHTON AND ASSOCIATES, INC.

testing schedule can be accomplished by the Geotechnical Consultant.

The Contractor shall stop or slow down the earthwork construction if these minimum standards are not met.

4.7 Compaction Test Locations
The Geotechnical Consultant shall document the approximate elevation and horizontal coordinates of each test location. The Contractor shall coordinate with the project surveyor to assure that sufficient grade stakes are established so that the Geotechnical Consultant can determine the test locations with sufficient accuracy. At a minimum, two grade stakes within a horizontal distance of 100 feet and vertically less than 5 feet apart from potential test locations shall be provided.

5.0 Subdrain Installation
Subdrain systems shall be installed in accordance with the approved geotechnical report(s), the grading plan. The Geotechnical Consultant may recommend additional subdrains and/or changes in subdrain extent, location, grade, or material depending on conditions encountered during grading. All subdrains shall be surveyed by a land surveyor/civil engineer for line and grade after installation and prior to burial. Sufficient time should be allowed by the Contractor for these surveys.

6.0 Excavation
Excavations, as well as over-excavation for remedial purposes, shall be evaluated by the Geotechnical Consultant during grading. Remedial removal depths shown on geotechnical plans are estimates only. The actual extent of removal shall be determined by the Geotechnical Consultant based on the field evaluation of exposed conditions during grading. Where fill-over-cut slopes are to be graded, the cut portion of the slope shall be made, evaluated, and accepted by the Geotechnical Consultant prior to placement of materials for construction of the fill portion of the slope, unless otherwise recommended by the Geotechnical Consultant.

7.0 Trench Backfills

7.1 Safety
The Contractor shall follow all OSHA and Cal/OSHA requirements for safety of trench excavations.

LEIGHTON AND ASSOCIATES, INC.

General Earthwork and Grading Specifications
-8-

7.2 Bedding and Backfill
All bedding and backfill of utility trenches shall be performed in accordance with the applicable provisions of Standard Specifications of Public Works Construction. Bedding material shall have a Sand Equivalent greater than 30 (SE>30). The bedding shall be placed to 1 foot over the top of the conduit and densified by jetting. Backfill shall be placed and densified to a minimum of 90 percent of relative compaction from 1 foot above the top of the conduit to the surface.

The Geotechnical Consultant shall test the trench backfill for relative compaction. At least one test should be made for every 300 feet of trench and 2 feet of fill.

7.3 Lift Thickness
Lift thickness of trench backfill shall not exceed those allowed in the Standard Specifications of Public Works Construction unless the Contractor can demonstrate to the Geotechnical Consultant that the fill lift can be compacted to the minimum relative compaction by his alternative equipment and method.

7.4 Observation and Testing
The jetting of the bedding around the conduits shall be observed by the Geotechnical Consultant.

GBA - IMPORTANT INFORMATION ABOUT THIS

GEOTECHNICAL ENGINEERING REPORT
Geotechnical-Engineering Report
Important Information about This
Subsurface problems are a principal cause of construction delays, cost overruns, claims, and disputes.

While you cannot eliminate all such risks, you can manage them. The following information is provided to help.

The Geoprofessional Business Association (GBA)
has prepared this advisory to help you – assumedly
a client representative – interpret and apply this
geotechnical-engineering report as effectively as
possible. In that way, you can benefit from a lowered
exposure to problems associated with subsurface
conditions at project sites and development of
them that, for decades, have been a principal cause
of construction delays, cost overruns, claims,
and disputes. If you have questions or want more
information about any of the issues discussed herein,
contact your GBA-member geotechnical engineer.

Active engagement in GBA exposes geotechnical
engineers to a wide array of risk-confrontation
techniques that can be of genuine benefit for
everyone involved with a construction project.

Understand the Geotechnical-Engineering Services
Provided for this Report
Geotechnical-engineering services typically include the planning, collection, interpretation, and analysis of exploratory data from widely spaced borings and/or test pits. Field data are combined with results from laboratory tests of soil and rock samples obtained from field exploration (if applicable), observations made during site reconnaissance, and historical information to form one or more models of the expected subsurface conditions beneath the site. Local geology and alterations of the site surface and subsurface by previous and proposed construction are also important considerations. Geotechnical engineers apply their engineering training, experience, and judgment to adapt the requirements of the prospective project to the subsurface model(s). Estimates are made of the subsurface conditions that will likely be exposed during construction as well as the expected performance of foundations and other structures being planned and/or affected by construction activities.

The culmination of these geotechnical-engineering services is typically a geotechnical-engineering report providing the data obtained, a discussion of the subsurface model(s), the engineering and geologic engineering assessments and analyses made, and the recommendations developed to satisfy the given requirements of the project. These reports may be titled investigations, explorations, studies, assessments, or evaluations.

Regardless of the title used, the geotechnical-engineering report is an engineering interpretation of the subsurface conditions within the context of the project and does not represent a close examination, systematic inquiry, or thorough investigation of all site and subsurface conditions.

Geotechnical-Engineering Services are Performed
for Specific Purposes, Persons, and Projects,
and At Specific Times
Geotechnical engineers structure their services to meet the specific needs, goals, and risk management preferences of their clients. A geotechnical-engineering study conducted for a given civil engineer will not likely meet the needs of a civil-works constructor or even a different civil engineer. Because each geotechnical-engineering study is unique, each geotechnical-engineering report is unique, prepared solely for the client.

Likewise, geotechnical-engineering services are performed for a specific project and purpose. For example, it is unlikely that a geotechnicalengineering study for a refrigerated warehouse will be the same as one prepared for a parking garage; and a few borings drilled during a preliminary study to evaluate site feasibility will not be adequate to develop geotechnical design recommendations for the project.

Do not rely on this report if your geotechnical engineer prepared it:
• for a different client;
• for a different project or purpose;
• for a different site (that may or may not include all or a portion of the original site); or
• before important events occurred at the site or adjacent to it; e.g., man-made events like construction or environmental remediation, or natural events like floods, droughts, earthquakes, or groundwater fluctuations.

Note, too, the reliability of a geotechnical-engineering report can be affected by the passage of time, because of factors like changed subsurface conditions; new or modified codes, standards, or regulations; or new techniques or tools. If you are the least bit uncertain about the continued reliability of this report, contact your geotechnical engineer before applying the recommendations in it. A minor amount of additional testing or analysis after the passage of time – if any is required at all – could prevent major problems.

Read this Report in Full
Costly problems have occurred because those relying on a geotechnicalengineering report did not read the report in its entirety. Do not rely on an executive summary. Do not read selective elements only. Read and refer to the report in full.

You Need to Inform Your Geotechnical Engineer
About Change
Your geotechnical engineer considered unique, project-specific factors when developing the scope of study behind this report and developing the confirmation-dependent recommendations the report conveys.

Typical changes that could erode the reliability of this report include those that affect:
• the site’s size or shape;
• the elevation, configuration, location, orientation,
function or weight of the proposed structure and
the desired performance criteria;
• the composition of the design team; or
• project ownership.

As a general rule, always inform your geotechnical engineer of project or site changes – even minor ones – and request an assessment of their impact. The geotechnical engineer who prepared this report cannot accept responsibility or liability for problems that arise because the geotechnical engineer was not informed about developments the engineer otherwise would have considered.

Most of the “Findings” Related in This Report
Are Professional Opinions
Before construction begins, geotechnical engineers explore a site’s subsurface using various sampling and testing procedures. Geotechnical engineers can observe actual subsurface conditions only at those specific locations where sampling and testing is performed. The data derived from that sampling and testing were reviewed by your geotechnical engineer, who then applied professional judgement to form opinions about subsurface conditions throughout the site. Actual sitewide-subsurface conditions may differ – maybe significantly – from those indicated in this report. Confront that risk by retaining your geotechnical engineer to serve on the design team through project completion to obtain informed guidance quickly, whenever needed.

This Report’s Recommendations Are
Confirmation-Dependent
The recommendations included in this report – including any options or alternatives – are confirmation-dependent. In other words, they are not final, because the geotechnical engineer who developed them relied heavily on judgement and opinion to do so. Your geotechnical engineer can finalize the recommendations only after observing actual subsurface conditions exposed during construction. If through observation your geotechnical engineer confirms that the conditions assumed to exist actually do exist, the recommendations can be relied upon, assuming no other changes have occurred. The geotechnical engineer who prepared this report cannot assume responsibility or liability for confirmation-dependent recommendations if you fail to retain that engineer to perform construction observation.

This Report Could Be Misinterpreted
Other design professionals’ misinterpretation of geotechnicalengineering reports has resulted in costly problems. Confront that risk by having your geotechnical engineer serve as a continuing member of the design team, to:
• confer with other design-team members;
• help develop specifications;
• review pertinent elements of other design professionals’ plans and specifications; and
• be available whenever geotechnical-engineering guidance is needed.

You should also confront the risk of constructors misinterpreting this report. Do so by retaining your geotechnical engineer to participate in prebid and preconstruction conferences and to perform constructionphase observations.

Give Constructors a Complete Report and Guidance
Some owners and design professionals mistakenly believe they can shift unanticipated-subsurface-conditions liability to constructors by limiting the information they provide for bid preparation. To help prevent the costly, contentious problems this practice has caused, include the complete geotechnical-engineering report, along with any attachments or appendices, with your contract documents, but be certain to note conspicuously that you’ve included the material for information purposes only. To avoid misunderstanding, you may also want to note that “informational purposes” means constructors have no right to rely on the interpretations, opinions, conclusions, or recommendations in the report. Be certain that constructors know they may learn about specific project requirements, including options selected from the report, only from the design drawings and specifications. Remind constructors that they may perform their own studies if they want to, and be sure to allow enough time to permit them to do so. Only then might you be in a position to give constructors the information available to you, while requiring them to at least share some of the financial responsibilities stemming from unanticipated conditions. Conducting prebid and preconstruction conferences can also be valuable in this respect.

Read Responsibility Provisions Closely
Some client representatives, design professionals, and constructors do not realize that geotechnical engineering is far less exact than other engineering disciplines. This happens in part because soil and rock on project sites are typically heterogeneous and not manufactured materials with well-defined engineering properties like steel and concrete. That lack of understanding has nurtured unrealistic expectations that have resulted in disappointments, delays, cost overruns, claims, and disputes.

To confront that risk, geotechnical engineers commonly include explanatory provisions in their reports. Sometimes labeled “limitations,” many of these provisions indicate where geotechnical engineers’ responsibilities begin and end, to help others recognize their own responsibilities and risks. Read these provisions closely. Ask questions.

Your geotechnical engineer should respond fully and frankly.

Geoenvironmental Concerns Are Not Covered
The personnel, equipment, and techniques used to perform an environmental study – e.g., a “phase-one” or “phase-two” environmental site assessment – differ significantly from those used to perform a geotechnical-engineering study. For that reason, a geotechnical-engineering report does not usually provide environmental findings, conclusions, or recommendations; e.g., about the likelihood of encountering underground storage tanks or regulated contaminants. Unanticipated subsurface environmental problems have led to project failures. If you have not obtained your own environmental information about the project site, ask your geotechnical consultant for a recommendation on how to find environmental risk-management guidance.

Obtain Professional Assistance to Deal with
Moisture Infiltration and Mold
While your geotechnical engineer may have addressed groundwater, water infiltration, or similar issues in this report, the engineer’s services were not designed, conducted, or intended to prevent migration of moisture – including water vapor – from the soil through building slabs and walls and into the building interior, where it can cause mold growth and material-performance deficiencies.

Accordingly, proper implementation of the geotechnical engineer’s recommendations will not of itself be sufficient to prevent moisture infiltration. Confront the risk of moisture infiltration by including building-envelope or mold specialists on the design team.

Geotechnical engineers are not building-envelope or mold specialists.

INTRODUCTION AND LOCATION
This paleontological resource assessment report has been completed for the Verano Residential Project, located between Interstate 10 and Vista Chino in the northern portion of the city of Cathedral City in Riverside County, California (Figure 1). More specifically, the project is situated north of the intersection of Verona Road and Ventura Drive and includes Assessor’s Parcel Numbers (APNs) 677-050-017, -018, -027, -029, and -031 through -034, which total 128.34 acres. In addition, there is an existing sand berm to the west of the project which is planned to be “reformed” as part of an off-site improvement that is attached to the project. An access road for sand berm maintenance will also be constructed as an off-site improvement along a portion of the northern project boundary. The subject property is within Section 5, Township 4 South, Range 5 East of the San Bernardino Baseline and Meridian, as shown on the U.S.

Geological Survey (USGS) (7.5-minute) Cathedral City, California topographic quadrangle map (Figure 2). The project proposes to clear the project parcels for the construction of a residential subdivision.

As the lead agency, the City of Cathedral City has required the preparation of a paleontological assessment to evaluate the project’s potential to yield paleontological resources.

The paleontological assessment of the project included a review of paleontological literature and fossil locality records for a previous project in the area, a review of the underlying geology, and recommendations to mitigate impacts to potential paleontological resources, if necessary.

II. REGULATORY SETTING
The California Environmental Quality Act (CEQA), which is patterned after the National Environmental Policy Act, is the overriding environmental regulation that sets the requirement for protecting California’s paleontological resources. CEQA mandates that governing permitting agencies (lead agencies) set their own guidelines for the protection of nonrenewable paleontological resources under their jurisdiction.

State of California
Under “Guidelines for Implementation of the California Environmental Quality Act,” as amended in December 2018 (California Code of Regulations [CCR] Title 14, Division 6, Chapter 3, Sections 15000 et seq.), procedures define the types of activities, persons, and public agencies required to comply with CEQA. Section 15063 of the CCR provides a process by which a lead agency may review a project’s potential impact to the environment, whether the impacts are significant, and provide recommendations, if necessary.

In CEQA’s Environmental Checklist Form, one of the questions to answer is, “Would the project directly or indirectly destroy a unique paleontological resource or site or unique geologic feature?” (Appendix G, Section VII, Part f). This is to ensure compliance with California Public Paleontological Assessment for the Verano Residential Project _____________________________________________________________________________________________________________________ 2 Resources Code Section 5097.5, the law by which protects nonrenewable resources including fossils, which is paraphrased below:

b) As used in this section, “public lands” means lands owned by, or under the jurisdiction of, the state, or any city, county, district, authority, or public corporation, or any agency thereof.
c) A violation of this section is a misdemeanor.

County of Riverside Guidelines
For Riverside County, policies concerning paleontological resources are addressed under the 2015 Multipurpose Open Space Element of the Riverside County General Plan and are as follows:

OS 19.6 Whenever existing information indicates that a site proposed for development has high paleontological sensitivity as shown on Figure OS-8, a paleontological resource impact mitigation program (PRIMP) shall be filed with the County Geologist prior to site grading. The PRIMP shall specify the steps to be taken to mitigate impacts to paleontological resources.

OS 19.7 Whenever existing information indicates that a site proposed for development has low paleontological sensitivity as shown on Figure OS-8 [in the General Plan], no direct mitigation is required unless a fossil is encountered during site development. Should a fossil be encountered, the County Geologist shall be notified and a paleontologist shall be retained by the project proponent. The paleontologist shall document the extent and potential significance of the paleontological resources on the site and establish appropriate mitigation measures for further site development.

OS 19.8 Whenever existing information indicates that a site proposed for development has undetermined paleontological sensitivity as shown on Figure OS-8 [in the General Plan], a report shall be filed with the County Geologist documenting the extent and potential significance of the paleontological resources on site and identifying mitigation measures for the fossil and for impacts to significant paleontological Paleontological Assessment for the Verano Residential Project _____________________________________________________________________________________________________________________ 6 resources prior to approval of that department.

OS 19.9 Whenever paleontological resources are found, the County Geologist shall direct them to a facility within Riverside County for their curation, including the Western Science Center [WSC] in the City of Hemet. (County of Riverside 2015a)
A comprehensive review of paleontological resources, including regulatory background, permitting conditions, significance thresholds, and procedures for the treatment of discovered resources, can be found in the County’s Draft Environmental Impact Report (County of Riverside 2015b).

City of Cathedral City Guidelines
The Cathedral City General Plan does not address paleontological resources (City of Cathedral City 2009).

III. GEOLOGY
Regionally, the project lies within the Salton Trough, a depressed structural block bounded on the west by the San Jacinto, Santa Rosa, and Coyote mountains and on the east by the San Andreas fault zone and Edom Hill, the Indio Hills, and the Mecca Hills (Norris and Webb 1990; Dibblee 2008). Based on mapping and descriptions by Rogers (1965) and Dibblee (2008), the project is within Holocene alluvium and/or dune sands. More precise mapping by Lancaster et al. (2012) indicates the geology at the surface of most of the project consists of late Holocene alluvial wash deposits, composed of unconsolidated sands and gravels deposited by recently active channels or streams (gray areas labeled “Qw” on Figure 3). Portions of the project’s western parcels are mapped as late Holocene eolian or sand dune deposits, composed of well sorted, wind-blown sand (pale green, dotted areas labeled “Qe” on Figure 3).

IV. PALEONTOLOGICAL RESOURCES
Definition
Paleontological resources are the remains of prehistoric life that have been preserved in geologic strata. These remains are called fossils and include bones, shells, teeth, and plant remains (including their impressions, casts, and molds) in the sedimentary matrix, as well as trace fossils such as footprints and burrows. Fossils are considered older than 5,000 years of age (Society of Vertebrate Paleontology 2010) but may include younger remains (subfossils) when viewed in the context of local extinction of the organism or habitat, for example. Fossils are considered a non-renewable resource under state and local guidelines (Section II of this report).

Paleontological Assessment for the Verano Residential Project _____________________________________________________________________________________________________________________ 8 Fossil Locality Search
A paleontological literature review and collections and locality records search was conducted for the project using data from prior, nearby projects performed by BFSA. Sources for past record searches include the San Bernardino County Museum (SBCM) and WSC. The nearest fossil localities held by the SBCM are several miles away to the south from the Pleistocene-aged Ocotillo Formation and consist of bone and tooth fragments of Equus sp., Mammut pacificus, and Mammuthus columbi (Kottcamp 2023). The WSC does not have fossil localities within this area of Coachella Valley (Stoneburg 2022).

According to published literature, the nearest fossil localities occur at Garnet Hill, approximately five miles northwest of the project, along the south side of Interstate 10. Garnet Hill mostly consists of an outcrop of the upper Miocene-aged Imperial Formation, documenting an early incursion of marine flooding of the proto-Gulf of California. A diverse fauna of late Miocene-aged invertebrates, mostly bivalve mollusks with some echinoderm remains (sand dollars and urchins), have been documented there since the 1930s. These specimens are held by the Museum of Paleontology at the University of California, Berkeley (Powell 1995).

Project Survey
On June 5 and 6, 2023, BFSA staff, under the supervision of Principal Investigator Todd A. Wirths, conducted an intuitive review of the property to determine if any paleontological resources were visible. The field methodology employed for the project included walking evenly spaced survey transects set approximately 15 meters apart while visually inspecting the ground surface. All potentially sensitive areas where paleontological resources might be located were closely inspected. The project was observed as previously graded, with housing pads and streets laid out. Stockpiles of sand and rock were present, as well as a cinder block wall. Paved roads from developed properties from the southeast extended into the project. Active deposits of windblown sand were present throughout the surfaces of the project. No bedrock outcrops were exposed that might suggest the presence of fossils. No paleontological resources, or evidence of paleontological resources, were observed during the survey.

V. PALEONTOLOGICAL SENSITIVITY
Overview
The degree of paleontological sensitivity of any particular area is based on a number of factors, including the documented presence of fossiliferous resources on a site or in nearby areas, the presence of documented fossils within a particular geologic formation or lithostratigraphic unit, and whether or not the original depositional environment of the sediments is one that might have been conducive to the accumulation of organic remains that may have become fossilized over time. Holocene alluvium is generally considered to be geologically too young to contain significant nonrenewable paleontological resources (i.e., fossils) and thus is typically assigned a low paleontological sensitivity. Pleistocene (more than 11,700-year-old) alluvial and alluvial fan Paleontological Assessment for the Verano Residential Project _____________________________________________________________________________________________________________________ 9 deposits in western Riverside County, however, often yield important Ice Age terrestrial vertebrate fossils, such as extinct mammoths, mastodons, giant ground sloths, extinct species of horse, bison, camel, saber-toothed cats, and others (Jefferson 1991). These Pleistocene sediments are thus accorded a high paleontological resource sensitivity.

Professional Standards
The Society of Vertebrate Paleontology (SVP 2010) has drafted guidelines that include four categories of paleontological sensitivity for geologic units (formations) that might be impacted by a proposed project, as listed below:
• High Potential: Rock units from which vertebrate or significant invertebrate, plant, or trace fossils have been recovered.
• Undetermined Potential: Rock units for which little information is available concerning their paleontological content, geologic age, and depositional environment, and that further study is needed to determine the potential of the rock unit. • Low Potential: Rock units that are poorly represented by fossil specimens in institutional collections or based upon a general scientific consensus that only preserve fossils in rare circumstances.
• No Potential: Rock units that have no potential to contain significant paleontological resources, such as high-grade metamorphic rocks and plutonic igneous rocks.

Using these criteria, the Holocene deposits mapped at the project may be considered to have a low potential to yield significant paleontological resources.

Riverside County Sensitivity
The County of Riverside Land Information System ranks the Holocene alluvium at the project properties as having a “Low” paleontological sensitivity (County of Riverside Land Information System 2023). The category “Low” indicates that fossils are unlikely to be encountered during excavation activities and, therefore, there is a low potential for significant paleontological resources that could be adversely impacted.

VI. CONCLUSION AND RECOMMENDATIONS
Based on the young age of the alluvium at the project, a low potential for the occurrence of paleontological resources within the young alluvium, and the lack of known paleontological localities in the area of the project, paleontological monitoring during earth disturbance activities at the project is not recommended. A paleontological resource impact mitigation program for the project is not warranted.

1.0 INTRODUCTION

1.1 Project Information
This report presents the findings of the Phase I Environmental Site Assessment [ESA] conducted by Earth Systems Pacific [Earth Systems] for the Verano Development, located west of Landau Boulevard and north of Verona Road in Cathedral City, Riverside County, California [the site]. This project was conducted for Northern Capital Partners Verano LLC in accordance with our proposal dated April 19, 2023. In 2022, Earth Systems conducted an ESA for property, which included the site, and summarized previous ESAs for the property. We understand the site plan is for residential development. This project has been performed at the request of the client for due diligence purposes. We are not aware of special requirements for this ESA.

1.2 Purpose and Scope of Work
The purpose of an ESA is to evaluate the potential for the presence of soil or groundwater contamination that may be present because of the past use, handling, storage, or disposal of hazardous materials or petroleum products on or near the property. The scope of work for this evaluation is based on the United States Environmental Protection Agency Final All Appropriate Inquiry Rule (2006) [US EPA AAI]; and, the ASTM Standard E1527‐13, Standard Practice for Environmental Site Assessments, and consisted of the tasks listed below.

Site Reconnaissance: This involved a visual reconnaissance of the site, noting physical evidence of potential contamination or possible sources of contamination; and observation of adjacent properties to identify readily observable visual evidence of possible impacts to the subject site. Figures depicting the site location and layout are presented in Appendix A.

Significant onsite features were photographed to document current conditions. Selected site photographs are presented in Appendix B.

Records Review: Records regarding the regulatory status and history of the site were evaluated regarding the possible presence of Recognized Environmental Conditions [REC].

Regulatory agency records were reviewed by obtaining a report listing known sites that generate, store, use, and/or have released hazardous materials from a firm that specializes in maintaining a database of this type of information. A copy of the agency database search report is presented in Appendix C and is discussed in Section 5.1. The search radius for the agency database search was in accordance with the US EPA AAI and ASTM standard E1527‐ 13 as measured from the site boundary. Other sources of information are listed in the references section of this report and may include the following categories of information (note that each category is utilized at the discretion of Environmental Professional [EP] until, in the EP’s opinion, sufficient data has been obtained):
 Historical aerial photographs
 Topographic maps
 California Department of Oil, Gas, and Geothermal Resources maps  Fire insurance maps
 Land title information
May 15, 2023 ‐ 2 ‐ File No. 305289‐002
Doc. No.: 23‐05‐703
EARTH SYSTEMS PACIFIC
 Local street directories
 Zoning/land use records
 Engineering and institutional controls, such as deed restrictions and restrictive zoning to a radius of ¼ mile, if contained in publicly available lists/registries  Tribal records of subject property and adjoining properties (if tribal land)  Local government records such as building department files  Environmental cleanup liens
 Prior reports
If the property was not previously developed, sources such as building department files and street directories were not reviewed. Relevant supporting documents are provided in Appendix D.

Interviews: Persons familiar with the site were interviewed (if possible) regarding the potential presence of RECs on the site or in a position to affect the site, including the site owner/operator/occupant, former site owners/operators/occupants (if reasonably accessible), neighboring property occupants (if the site is abandoned), and selected government personnel likely to have information regarding environmental conditions at or near the site. Information from persons who were successfully contacted is presented in Section 6.

Report Preparation: This report was prepared to present our findings, conclusions, and recommendations.

1.3 Definitions
ASTM E1527‐13 provides definitions for 102 terms and 27 acronyms used in the ESA process.

Earth Systems endeavors to use these terms and acronyms within the meaning provided by ASTM E1527‐13. The majority of these terms are either obvious in their meaning or are seldom used in this report, but a few are significant enough to warrant defining here, as follows:

Site: The term “site” is used in place of the term “property” as defined by ASTM E1527‐13 and is the physical location that is the subject of the assessment. The site can include more than one parcel of land, or only a portion of a parcel of land, depending on the needs of the client. ESAs focus primarily on activities that occur within the boundaries of the site, or that could potentially affect conditions and activities within the boundaries of the site. RECs on offsite properties that are not likely to affect the site are not considered to be RECs for the subject site.

Recognized Environmental Condition [REC]: the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: due to a release to the environment; under conditions indicative of a release to the environment; or under conditions that pose a material threat of a future release to the environment. The term does not include de minimis conditions.

May 15, 2023 ‐ 3 ‐ File No. 305289‐002
Doc. No.: 23‐05‐703
EARTH SYSTEMS PACIFIC
Controlled Recognized Environmental Condition [CREC]: An REC resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority, with hazardous substances or petroleum projects allowed to remain in place subject to the implementation of required controls.

Historical Recognized Environmental Condition [HREC]: A past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority or meeting unrestricted use criteria established by a regulatory authority, without subjecting the property to any required controls (such as use restriction). HRECs are no longer RECs for a site.

De minimus: A condition that generally does not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies.

Environmental Professional [EP]: An EP is defined by US EPA AAI as “a person who possesses sufficient specific education, training, and experience necessary to exercise professional judgment to develop opinions and conclusions regarding conditions indicative of releases or threatened releases (of hazardous substances) on, at, in, or to a property, sufficient to meet the objectives and performance factors (of the rule).” Specific minimum credentials are required by US EPA AAI and ASTM E1527‐13 to be identified as an EP.

User: The “user” of the report is defined by ASTM Practice E1527‐13 as the party for whom the assessment is being conducted (the “client”), not the EP.

1.4 Qualifications
Work on this project was performed under the direct supervision of an Environmental Professional [EP], in accordance with the US EPA AAI and ASTM E1527‐13 requirements. Mr.

1.5 Exclusions and Data Gaps
The scope of work for this ESA did not include testing the air, groundwater, soil, or building materials for the presence of hazardous constituents.

The US EPA AAI and ASTM E1527‐13 require that gaps in the data used in evaluating the site be identified. Data gaps encountered in this project, and their significance to the project, are summarized below.

EARTH SYSTEMS PACIFIC
 As stated in the proposal, land title information would only be reviewed if furnished by the Client. Land title information was not provided to Earth Systems, and therefore was not reviewed. Because of the availability of other data sources (e.g., aerial photographs and prior reports), the lack of title information is not considered to be significant.  Prior owners, operators, or employees of the site or owners, operators, or employees of adjacent properties could not be contacted to be interviewed. This data gap is not considered significant given the availability of other sources of information; and the existing development having been limited to residential grading and street development.  City building department records were not requested because structures were not built on the site since the prior evaluation.
 Historical street directories were not requested since a street address is needed for that research. This data gap is not considered significant due to the site’s essentially vacant nature and residential or undeveloped status of the vicinity.  Sanborn maps were not available for the site. This data gap is not considered to be significant since the site and much of the vicinity is undeveloped and developed properties nearby are residential.

Further investigations regarding the data gaps do not appear warranted.

1.6 Limitations and Reliance
This report has been prepared for the exclusive use of Northern Capital Partners LLC. Other parties participating in the transaction for which this project was conducted may also use the information presented in this report, provided said parties agree that Earth Systems shall have no additional liability arising from such use than described in the contract under which this project was conducted. Any other use of or reliance on the information and opinions contained in this report without the written authorization of Earth Systems is at the sole risk of the user (to apply for written authorization to rely on this report, please complete and submit the application provided in Appendix F).

Note that the conclusions and recommendations rendered in this report are opinions based on readily available information obtained to date within the scope of the work authorized by the client and apply only to site conditions as of the date of the site visit. The scope of work for this project was developed to address the needs of the client as part of a property transaction (purchase, sale, refinance, etc.) and may not meet the needs of other users.

It should be noted that any level of assessment cannot ascertain that a property is completely free of chemical or toxic substances. We believe the scope of work has been appropriate to allow the client to make an informed business decision. According to US EPA AAI and ASTM E1527‐13:
the “shelf life” of an ESA report is six months; an “Update” can be provided to the client within the first year of the report’s publication (at an additional cost); and if the report is older than one year, the ESA should be re‐conducted. Changes in site conditions can render this report obsolete within a shorter period of time. Use of this report outside of these time frames or after site May 15, 2023 ‐ 5 ‐ File No. 305289‐002

conditions have changed is at the sole risk of the user and without liability and legal exposure to Earth Systems.

The results contained in this report are based upon the information acquired during the assessment, including information obtained from third parties. Earth Systems makes no claim as to the accuracy of the information obtained from others. In addition, it is possible that variations exist beyond or between points evaluated during this assessment, and that changes in conditions can occur in the future due to the works of man, contaminant migration, variations in rainfall or temperature, a broadening of knowledge, changes in regulatory standards, and/or other factors not apparent at the time of the field investigation. It should also be noted that in blow‐sand areas, sand can accumulate quickly behind windbreaks. Consequently, materials can be buried out of view by natural wind‐blown sand in a relatively short period of time under favorable conditions.

The services performed by Earth Systems have been conducted in a manner consistent with the level of care and skill ordinarily exercised by members of our profession currently practicing under similar conditions in the site vicinity. No warranty, express or implied, is offered.

2.3 Township, Range, Section
The site is located in the north half of Section 5, Township 4 South, Range 5 East.

2.4 Site Boundaries
Portions of the property boundaries are defined by paved or graded roadways, and the west boundary of the site is defined by a levee. Otherwise, boundaries were estimated based on the RCIT map with aerial photo, which depicts APN boundaries.

2.5 Current Development and Access
The site is currently rough graded or undeveloped land accessed via locked gates from Verona Road parallel to the south boundary, and Rio Pecos Drive roughly parallel to the southeast boundary.

2.6 Zoning/Land Use Records
Zoning/Land Use information was obtained from the City of Cathedral City Planning Department website, which indicated that the property usage is designated as shown below:

APN Zoning Designation/Land Use Type

2.7 Site Topography
The surface of the site slopes to the southeast at a slight angle. The elevation of the site ranges from about 437 feet above mean sea level in the southeast corner (Rio Pecos Drive) to about 488 feet above mean sea level in the northwest corner.

2.8 Surface Water Bodies
Surface water bodies are not present on the site, either as lakes or streams. A portion of the Morongo Wash once crossed the site in the north half of Section 5 but a levee was constructed across the northwest end of the Wash to divert surface water southward to the main Whitewater River channel approximately 1 mile southwest of the subject site. Rainwater appears to infiltrate May 15, 2023 ‐ 7 ‐ File No. 305289‐002
Doc. No.: 23‐05‐703
EARTH SYSTEMS PACIFIC
within the site. Water bodies are not located in a position to transport contaminants onto the site or be readily affected by contaminants released at the site.

2.9 Geology and Hydrogeology
The site is located in the Coachella Valley of Southern California. The Coachella Valley is part of the tectonically active Salton Trough, which is a closed, internally draining basin bound by the San Jacinto and Santa Rosa Mountains to the southwest; the San Bernardino Mountains to the northwest; and the Little San Bernardino and Orocopia Mountains to the northeast and east.

These mountain ranges, and the basement rock underlying the Coachella Valley, are primarily composed of granitic and metamorphic rock. Within the Coachella Valley, the basement complex is overlain by a series of unconsolidated and semi‐consolidated continental clastic sediments eroded from the surrounding mountain ranges; lacustrine deposits of ancient Lake Cahuilla; and wind‐blown sand deposited in the active blow‐sand area of Riverside County (DWR, 1964). The site is located on continental clastic sediments (overlain by aeolian deposits) eroded from the mountains north and northeast of the site.

The northwest trending San Andreas fault zone is the major geologic feature of the Coachella Valley. The Banning, Mission Creek, and Garnet Hill faults, which are part of the San Andreas fault system, divide the Coachella Valley into four distinct hydrogeologic subbasins. Each subbasin is further divided into subareas, based on either the type of water‐bearing formation, water quality, areas of confined groundwater, forebay areas, groundwater divides, or surface water divides. The site is located within the Palm Springs subarea of the Indio subbasin. This subarea is bounded by the Garnet Hill fault to the northeast, the San Jacinto and Santa Rosa Mountains to the west and south, and the adjacent Thermal subarea of the Indio subbasin to the east. Groundwater in this subarea generally flows in a southeasterly direction toward the Salton Sea from the main recharge areas along the base of the San Jacinto Mountains and near the San Gorgonio Pass. The alluvial materials within this subarea are primarily heterogeneous alluvial fan deposits exhibiting little sorting and with a low percentage of fine‐grained material. The transmissivity (a measure of the capability of an aquifer to transmit water) of the aquifer in the Indio subbasin was calculated in two wells to be 60,000 to 250,000 gallons per day per foot‐width of aquifer, which is relatively high (DWR, 1964).

The depth to groundwater at the site was evaluated via data available on the California Statewide Groundwater Elevation Monitoring System [CASGEM] database. Groundwater elevation in a CASGEM well (ID: 49816) located approximately 2.5 miles west‐northwest of the site and at a ground surface elevation of 550 feet, was ‐314.97 feet on October 11, 2021; and ‐306.13 feet on April 22, 2022.

3.0 SITE RECONNAISSANCE

3.1 Onsite Observations

EARTH SYSTEMS PACIFIC

3.1.1 Overall site conditions
 Site conditions were very similar to the 2022 Phase I site visit.  Several of the trash items identified in 2022 have been subsequently cleaned up.
 The “imported soils” identified at the time of the 2022 ESA appeared to have been associated with what was called “the staging area,” where equipment was stored during the buildout on the west side of site.  The staging area was cleared this time and the piles were gone.
 The site is undeveloped sandy ground surrounding a developed community.  Except for Tamarisk trees parallel to the northeast and west boundaries of the site, vegetation consisted of small mounds of native desert brush. The vegetation showed no sign of stress except for the lack of water.
 Access to the site was limited to paved roads (Landau Boulevard, Verona Road, and Rio Pecos Road) associated with the residential development in the immediate vicinity.

Fencing blocked direct access to the site, except where the fencing was breached, or gates were opened.
 Evidence was not seen of hazardous trash, such as drums, fuel tanks, oil products, batteries, or other potentially hazardous materials.

3.1.2 Individual APNs
 APN 677‐050‐015:
o Narrow parcel mostly covered with blow sand (Photo 1).  APN 677‐050‐016:
o Small walled parcel covered with blow sand (Photo 2).  APN 677‐050‐017):
o Fenced area has old mulch that is sand covered (Photo 5). o North of fenced area small piles of asphalt and rock debris (Photo 6).  Hazardous materials were not observed in the debris piles.
 APN 677‐050‐018:
o Along southern portions of parcel are areas of debris mostly where it was found in 2022.  There were minor construction debris (concrete, rocks, etc.), small piles of asphalt, old mulch piles and old wooden‐wire fencing (Photos 3‐5).  APN 677‐050‐023:
o Minor asphalt and concrete piles, and trash and tires at northwest corner of lot.  All nonhazardous (Photo 6).  Minor domestic debris associated with Verona Road and Landau Boulevard.

4.0 HISTORICAL INFORMATION
Information regarding the history of the site was obtained from various sources, as listed in the references section of this report.

4.1 Prior Reports
Earth Systems conducted for the site a Phase I Environmental Site Assessment (Earth Systems, 2013), a Phase I Environmental Site Assessment Update (Earth Systems, 2014), and a second ESA (Earth Systems, 2022). In general, these investigations did not find evidence that the site was adversely affected by activities in the site vicinity; the site was not identified in the agency database reviews; and the sites in the site vicinity did not appear to pose a risk to the subject site based on the status of those sites, the distance, or direction from the subject site, or the nature of the issue(s) at those sites. RECs were not identified in the 2013 ESA or the 2014 Update, and evidence of the on‐site manufacture, storage, or disposal of hazardous materials was not observed.

The 2022 ESA identified the following REC:
“(s)everal dozen mounds of what appeared to be soil were stored on Parcel F2 by 2016 and were gone (or graded onsite) by 2020. The origin of the mounds is not known, though they could have been imported from offsite. These could be considered a REC, due to the potential for hazardous material residues (petroleum hydrocarbons, pesticides residues) to be present in the soil.” Earth Systems recommended soil sampling with analysis for OCPs and petroleum hydrocarbons.

See Section 7.0 for discussion of this REC.

The southeast sixth of APN 677‐050‐032 (former Parcel F2) appears to have a coating of dust suppressant. A staging area with vehicles and potentially a construction office were at the southeast corner of APN 677‐050‐032. Parcels offsite to the east of APNs APN 677‐050‐031, ‐032, 033; southeast of ‐034, and south of ‐027 and ‐018 were nearly fully developed for residential usage.

Historical information footnotes:

We attempted to obtain historical information from a standard set of resources, including historical aerial photographs, historical USGS topographic maps, Sanborn fire insurance maps, historical street directories, chain‐of‐title documents, city building permit files, and personnel interview. However, historical information was not obtained from some sources, as follows:

Sanborn Fire Insurance maps: Sanborn maps for the site and vicinity were requested from ERIS, a firm that specializes in maintaining this type of information. ERIS indicated that “no information was found for your site or adjacent properties.”
Historical City Directories: Actual addresses are required to conduct searches using historical street directories. The County Assessor’s reports indicate that addresses have not been assigned to the site.

Chain of Title documents: Chain of title documents were not provided prior to publication of this report and, therefore, were not reviewed.

City Building Permits were not requested because of the lack of significant development of the site.

County Assessor’s Office: The reports indicate that there are no building developments for the site.

5.0 RECORDS REVIEW

5.1 Agency Database Search Report
A report summarizing the information available from regulatory agencies regarding sites that generate, store, use, and/or have released hazardous materials was obtained from a firm that specializes in maintaining a database of this type of information. The publications reviewed in the database search are referenced in the database report, presented in Appendix C. The search radii used for each list were in accordance with the US EPA AAI and ASTM E1527‐13 guidelines as measured from the site boundary. Significant information obtained in the database search is summarized below.
 The site is not listed in the database report.
 Three sites listed five time were identified within the search radii and are listed in the database report as follows:

May 15, 2023 ‐ 12 ‐ File No. 305289‐002
Doc. No.: 23‐05‐703
EARTH SYSTEMS PACIFIC
o Shields Industries, Inc. (Map Key 1), located at 67265 Verona Road, on the opposite side of Verona Road from the southwest portion of the subject site, is listed in the database report as Hazardous Waste Generator [HAZGEN] on the Hazardous Waste Information System [HAZNET] database, which documents hazardous waste manifest data. The California Department of Toxic Substances Control [DTSC] monitors the HAZNET database. However, this address is for a single‐family home. It is unlikely that hazardous waste is generated at this location, which may be the address for one of the company principals. No problems regarding disposal of hazardous materials are reported for the site and this is not a REC.
o Rio Vista (Housing Development) (Map Key 2), located at Verona and Landau (streets), south and east of the subject site, is included in the following databases:
 US EPA Facility Registry System [FINDS/FRS], which “identifies facilities, sites or places subject to environmental regulations or of environmental interest.” Inventory Database [FID] for a UST onsite. The report cites the latitude and longitude as the intersection of Landau and Verona and the description as “General contractors‐single‐ family houses” (Appendix D). Links in the report cite the following sources of information:
 Air Facility System [AFS] “contains emissions, compliance and enforcement data on stationary sources of air pollution. Regulated sources cover a wide spectrum; from large industrial facilities to relatively small operations such as dry cleaners.

AFS does not contain data on facilities that are solely asbestos demolition and/or renovation contractors, or landfills. ECHO Clean Air Act data from AFS are frozen and reflect data as of October 17, 2014; the EPA retired this system for Clean Air Act stationary sources and transitioned to ICIS‐Air” (Appendix D). The listing was last updated August 16, 2011.
 Integrated Compliance Information System ‐ National Pollutant Discharge Elimination System [ICIS‐NPDES] “is an information management system maintained by the Office of Compliance to track permit compliance and enforcement status of facilities regulated by the NPDES under the Clean Water Act. This data includes permit, inspection, violation and enforcement action information for applicable ICIS records” (Appendix D). The listing was last updated October 19, 2014.

Due to the length of time since last updated and the Environmental Interest Type identified as “Air minor” these are not considered to be RECs. o Flat Top Mtn. Deposit (Map Key 3), located 0.89 mile east‐northeast of the subject site, is included in the Mineral Resource Data System [MRDS] as a past producer of sand and gravel for the construction industry (Appendix D). This is not considered to be a REC.  The database search report has three listings categorized as unmapped, due to vague address listings or the inability of the automated search system to identify the location of the release site. A review of these listings did not identify them to be within the search radii. The May 15, 2023 ‐ 13 ‐ File No. 305289‐002

EARTH SYSTEMS PACIFIC
unmapped site does not appear to pose a concern for the site due to the distance, direction, status, or nature of the issue at that site.

The sites identified in the agency database review do not appear to be RECs for the subject site due to the distance, direction, status, or nature of the issue at these sites.

5.2 California EPA, State Water Resources Control Board The California Environmental Protection Agency [EPA], State Water Resources Control Board [SWRCB] GeoTracker website was accessed to research records on file regarding known problems at the site address. The database search did not find results for the site or properties in the vicinity.

5.3 California Department of Toxic Substances Control
The California Department of Toxic Substances Control [DTSC] EnviroStor website was accessed to research records on file regarding known problems at the site address or in the site vicinity.

The database search did not find results for the site or properties in the vicinity.

5.4 Vapor Encroachment
ASTM E1527‐13, Standard Practice for Environmental Assessments: Phase I Environmental Assessment Process, specifies RECs related to petroleum releases. As defined in Section 1.3, a REC is “the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: due to a release to the environment; under conditions indicative of a release to the environment; or under conditions that pose a material threat of a future release to the environment.”
Based on reviews of the Agency Database Search Report, Geotracker website, and Envirostor website (Sections 5.1, 5.2, 5.2), petroleum vapor encroachment from facilities offsite were not identified.

5.5 Tribal Records
This site is within ¼ mile of tribal land. Agua Caliente Band of Cahuilla Indians [ACBCI] staff was previously contacted regarding records on file for ACBCI tribal lands. ACBCI staff stated that ACBCI has signed a “memo of understanding” with the Riverside County Department of Environmental Health [RCDEH] that is included in ACBCI lease agreements, thereby holding tenants to abide by county guidelines regarding environmental issues onsite. Therefore, records on file for the site should duplicate records on file with the RCDEH.

5.6 Engineering and Institutional Controls
Engineering and Institutional Controls [EICs] (e.g., deed restrictions and restrictive zoning) were not identified for the subject site in the agency database search report. Engineering and Institutional Controls to a radius of ¼ mile were not identified.

5.7 Environmental Cleanup Liens
Recorded Environmental Cleanup Liens [ECLs] on a property are indicators that contamination exists or existed at the site. ECLs are “encumbrances on a property for the recovery of incurred cleanup costs on the part of a state, tribal, or federal government agency or other third party” (EPA 2005). In the EP’s judgment, an ECL is not likely to be an issue onsite or in the vicinity due to lack of evidence that a release has occurred onsite.

5.8 California Department of Conservation, Geologic Energy Management Division The California Department of Conservation, Geologic Energy Management Division [CalGEM] maps on the CalGEM website were reviewed for information regarding historic oil‐well or geothermal drilling activities near the site. The maps and databases did not depict permitted oil or geothermal wells within 1 mile of the site.

6.0 INTERVIEWS, GENERAL RESEARCH, AND PRIOR REPORTS

6.1 Current Owners/Occupants/Operators
Mr. David DiRienzo, President and founder of UrbanWest (a real estate development and investment firm involved in 2023 planning of Verano Development), was contacted regarding his knowledge of the site. In 2022, Mr. DiRienzo and UrbanWest “created project designs” for “138 acres of residential development land within the Verano Master Planned Community in Cathedral City, California” (Linkedin, 2023). Mr. DiRienzo provided the following information:
 Mr. DiRienzo has no knowledge/suspicion of the release of hazardous materials onsite.  He is unaware of USTs or above‐ground storage tanks [ASTs] on site now or in the past.  Mr. DiRienzo stated that there are no ECLs assigned to the site.  The site has been consistently monitored to ward against illegal dumping.

6.2 Past Owners/Occupants/Operators
Contact information for prior owners, operators, or occupants was not readily available.

6.3 Owners/Occupants of Neighboring Properties
The US EPA recommends that interviews with persons on adjoining properties be conducted for properties that are “abandoned.” The subject site is under active ownership and consistently monitored. Therefore, the site is not considered to be abandoned and interviews of owners/occupants of neighboring properties were not conducted.

7.0 SUMMARY AND CONCLUSIONS
This report presents the findings of the Phase I Environmental Site Assessment [ESA] conducted by Earth Systems Pacific [Earth Systems] for Verano Development (APNs 677‐050‐015, ‐016, ‐017, ‐018, ‐023, ‐027, ‐029, ‐031, ‐032, ‐033, and ‐034), located west of Landau Boulevard and north May 15, 2023 ‐ 15 ‐ File No. 305289‐002

13. Exceptions to or deletions from this practice are described in Sections 1.5 and 1.6 of this report. The purpose of this assessment was to evaluate the site for the presence of Recognized Environmental Conditions [REC] related to the current or past use, handling, storage, or disposal of hazardous materials or petroleum products on or near the subject property. This assessment has revealed no evidence of RECs in connection with this property except as discussed in the project summary presented below. Our findings and conclusions are summarized as follows:

1. The site was observed to consist of mass‐graded residential lots and undeveloped native desert.

2. Construction debris, household debris, and windblown trash were noted scattered in some areas of the site. The debris onsite does not appear to contain hazardous materials and is not considered a REC. Small piles of asphalt rubble and tires are not a REC but should be removed appropriately from the site.

3. Evidence was not observed during the site visit of the presence of storage tanks, water wells, drywells, potential PCB‐containing equipment (such as transformers), sumps, pits, ponds (other than an empty retention basin), lagoons, stained soil, stressed vegetation (other than due to weather), or onsite septic system.

4. Evidence of the onsite use, storage, or disposal of hazardous materials was not observed.

5. In 2022 Earth Systems recommended that soil piles on APN 677‐050‐032 be sampled and analyzed for potential hazardous substances. The soil piles and staging area were not in evidence at the time of this ESA site visit.

6. The site vicinity consists of residential and undeveloped properties. Evidence was not observed that the site was adversely affected by activities in the site vicinity.

7. The site was not identified in the agency database review. The sites identified in the agency database review do not appear to be RECs for the subject site due to the distance, direction, status, or nature of the issue at these sites.

8. The sites in the site vicinity do not appear to pose a risk to the subject site based on the status of those sites, the distance, or direction from the subject site, or the nature of the issue(s) at those sites.

8.0 RECOMMENDATIONS
RECs were not identified for this site. Therefore, further investigations do not appear warranted. ‐o0o‐

PFAS Waste Transfers from RCRA e-Manifest : rr-PFAS E-MANIFEST-bb This Per- and Poly-Fluoroalkyl Substances (PFAS) Waste Transfers dataset is made available via the U.S. Environmental Protection Agency's (EPA) PFAS Analytic Tools. Every shipment of hazardous waste in the U.S. must be accompanied by a shipment manifest, which is a critical component of the cradle-to-grave tracking of wastes mandated by the Resource Conservation and Recovery Act (RCRA). According to the EPA, currently no Federal Waste Code exists for any PFAS compounds. To work around the lack of PFAS waste codes in the RCRA database, EPA developed the PFAS Transfers dataset by mining e-Manifest records containing at least one of these common PFAS keywords: • PFAS • PFOA • PFOS • PERFL • AFFF • GENX • GEN-X (plus the Vermont state-specific waste codes). Limitations: Amount or concentration of PFAS being transferred cannot be determined from the manifest information. Keyword searches may misidentify some manifest records that do not contain PFAS. This dataset should also not be considered to be exhaustive of all PFAS waste transfers.

Database Descriptions: This section provides a detailed explanation for each database including: source, information available, time coverage, and acronyms used. They are listed in alphabetic order.

Detail Report: This is the section of the report which provides the most detail for each individual record. Records are summarized by location, starting with the project property followed by records in closest proximity.

Distance: The distance value is the distance between plotted points, not necessarily the distance between the sites' boundaries. All values are an approximation.

Direction: The direction value is the compass direction of the site in respect to the project property and/or center point of the report.

Elevation: The elevation value is taken from the location at which the records for the site address have been plotted. All values are an approximation.

Source: Google Elevation API.

Executive Summary: This portion of the report is divided into 3 sections:
'Report Summary'- Displays a chart indicating how many records fall on the project property and, within the report search radii. 'Site Report Summary'-Project Property'- This section lists all the records which fall on the project property. For more details, see the 'Detail Report' section.
'Site Report Summary-Surrounding Properties'- This section summarizes all records on adjacent properties, listing them in order of proximity from the project property. For more details, see the 'Detail Report' section.

Map Key: The map key number is assigned according to closest proximity from the project property. Map Key numbers always start at #1. The project property will always have a map key of '1' if records are available. If there is a number in brackets beside the main number, this will indicate the number of records on that specific property. If there is no number in brackets, there is only one record for that property.

The symbol and colour used indicates 'elevation': the red inverted triangle will dictate 'ERIS Sites with Lower Elevation', the yellow triangle will dictate 'ERIS Sites with Higher Elevation' and the orange square will dictate 'ERIS Sites with Same Elevation.' Unplottables: These are records that could not be mapped due to various reasons, including limited geographic information. These records may or may not be in your study area, and are included as reference.

Earth Systems Resume
Alexander Schriener Jr., P.G. Associate Geologist
Mr. Schriener has over thirty‐seven years as an alternative energy, natural resource and environmental geologist. He has seven years consulting experience specifically in the field of environmental geology. Mr. Schriener also manages geothermal energy services for Earth Systems.

Key Qualifications:

Mr. Schriener experience performing Phase I Environmental Site Assessments to evaluate the potential presence of soil and groundwater contamination at industrial, commercial, residential and agricultural properties, as well as vacant land. He has performed Phase II Investigations to evaluate whether contamination is actually present, and the concentration and extent of those contaminants. If contaminates are found, then site remediation is required. Mr. Schriener has successfully performed numerous Phase III site remediation and brought sites to closure with public agencies.

Mr. Schriener has over thirty years’ experience in geothermal resource management, development and exploration.

Mr. Schriener has also been an expert witness in legal proceedings involving geothermal energy management and well drilling.

Relevant Project Experience:

Gasoline Station Investigation and Closure
Mr. Schriener was project manager for an assessment of gasoline stations with potential leaking underground storage tanks. He placed monitoring wells, completed groundwater and soil assessments and successfully got agency closure on 5 of 7 sites he was managed between 2004 and 2008.

Phase II Site Assessments and Phase III Site Closure
Mr. Schriener was project manager on numerous Phase II site assessments in the Coachella Valley and southern California. At each site, he selected the investigative methods, oversaw sampling and analysis activities, reviewed the laboratory data, and prepared a report meeting the requirements of the lender or agency. If contamination was found, Mr. Schriener prepared a work plan to mitigate the site and obtain closure. Significant sites that were evaluated and closure was obtained included several parcels of farm land over 20 acres each, a metal salvage yard, an industrial warehouse, a former cattle ranch and former sewage treatment facility.

Geothermal Exploration and Development
Mr. Schriener over thirty years’ experience in geothermal energy including geology, geochemistry, geophysics, drilling, reservoir modeling, land leasing, exploration, and field development. He has managed the resource staff and activities in the three major geothermal fields in California: The Geysers, Coso and The Salton Sea, as well as Desert Peak in Nevada and Roosevelt/Blundell in Utah. Mr. Schriener has regularly managed an annual drilling and resource department budget of over $10 Million. .

1.0 INTRODUCTION

1.1 GEOGRAPHIC SETTING
The proposed Verano project will be part of the master planned community named Rio Vista Village at Cathedral City, California. This report focuses on the portion of the Verano project (herein known as the “project”) that is located within Drainage area “D” as identified in the Rio Vista Village Master Plan Drainage Report Tract 28639-1 for Rio Vista Village, dated May 2001.

The project encompasses TTM 38709 and TTM 38710. The total project site is approximately

12.84 acres with a net disturbed area of 12.84 acres. It is bounded by an empty lot to the north, Rio Guadalupe Rd to the west, Avenida Quintana to the east, and Rio Rosalia Dr to the south.

The project site is vacant and undeveloped under its existing conditions. Adjacent development surrounding the area site includes single family residences, a stormwater channel, and undeveloped areas. See Figure 1 below for the project location map.

There is no existing storm drain system on site. There are existing Retention Basins C and D located in between Rio Vista Dr that will be utilized for this project. The proposed project consists of the construction of various buildings, landscape areas, drive aisles, sidewalks, parking areas, wall, water quality BMPs and wet/dry utilities.

1.2 PURPOSE OF THIS REPORT
The purpose of this report is to accomplish the following objective:

To determine hydrologic impacts resulting from the proposed development. Impacts are determined based on the comparison between the pre-development condition and the postdevelopment condition. This hydrology report will also provide the peak flow rates for 10-year and 100-year at 24hr duration for post development condition and determine if the proposed storm drain system will be sufficient to convey the runoff generated by the proposed improvements. 100yr-24Hr Storm frequency unit Hydrograph will be used to calculate the runoff volume generated at post condition. Post development condition will also utilize the pro-rated volume provided for the existing retention basin, D, as shown on the previously approved Master WQMP (M-WQMP) for Rio Vista Village. This will be considered in evaluating the peak flow rate after retention.

2.0 PRE-DEVELOPMENT CONDITION

2.1 PRE-DEVELOPMENT TOPOGRAPHY
The project site is vacant and undeveloped under existing conditions. Adjacent land uses include single family residences and undeveloped property. The pre-development drainage area is approximately 12.84 acres. The overall property moderately slopes downward to the southerly direction towards the existing retention basins.

2.2 PRE-DEVELOPMENT DRAINAGE SYSTEM
The existing site is an undeveloped property with no storm drain system within the site. The project site is located within Drainage area “D” as identified in the Rio Vista Village Master Plan Drainage Report Tract 28639-1 for Rio Vista Village, dated May 2001. The storm runoff from the site sheet flows towards the southerly direction to the existing retention basin “D” located between Rio Vista Drive. These runoffs will be part of the Whitewater watershed area which will drain to Whitewater River then to the Coachella Valley Storm Water Channel.

3.0 POST DEVELOPMENT CONDITION

3.1 POST DEVELOPMENT
The proposed development includes single-family residences, landscape areas, parking lots, and drive aisles. This proposed development will increase the impervious area of the site to 65%. The post-development drainage area for this development is approximately 12.84 acres. This development will utilize the existing Retention Basin D for treatment control as well as to address flood control requirements. Per the M-WQMP, the Retention Basin “D” was designed with the capacity to retain for the 100-year, 24-hour storm event. This means the design of the existing basins exceed the current NPDES WQMP requirements per Cathedral City Municipal Code Title 8 § 8.24.070 requiring a minimum storage for 100yr-3Hr duration storm event. The Autodesk Civil3D Hydraflow Unit Hydrograph and RCFC & WCD data was utilized to calculate this. Runoff from the proposed development site will sheet flow through the curb and gutters to 3 locations and then to the on-site storm drain system and eventually to the existing retention basin D.

In addition, the improvements will also include installation of appropriate drainage facilities, other dry and wet utilities, and LID BMPs to mitigate water quality objectives.

3.2 PROPOSED DRAINAGE FACILITY
This post development condition will have three drainage areas as shown on the Post Development Drainage Maps. Drainage areas P-A, P-B and P-C will drain to three respective locations and then to the existing storm drain systems which will ultimately flow towards the existing Retention Basin “D”. Discharge peak flow rates will be calculated per 100yr-24hr storm event. The capacity of the street and catch basins will also be designed per 100-yr storm event.

Proposed development must also peak flow rate must not exceed pre-development condition at 100yr-24h4 storm frequency. This will be achieved by the utilization of the existing retention basins.

Proposed drainage structures and pipes are shown in the Hydrology Maps in Appendix 5.

4.0 HYDROLOGY AND HYDRAULIC STUDY

4.1 METHODOLOGY
This study was prepared in conformance with the Riverside County Hydrology Manual. Autodesk Civil3D Hydraflow Unit Hydrograph Calculator with the rainfall intensity and precipitation data from RCFC & WCD was used to determine the hydrograph volume based on 100-year, 24hr storm duration. Soil type “A” was used for the site per the RCFC & WCD Hydrologic Soil Map for Cathedral City (Plate C-1.36) Methodology and supportive data for the hydrologic calculations may be found in this report, and in the “Riverside County Flood Control and Water Conservation District Hydrology Manual”.

The results of the analysis are included in this report in Appendix 2 and 4.

5.0 RESULTS AND CONCLUSIONS
The purpose of this drainage analysis is to identify the need to keep the post-development runoff volume and peak flow rate the same as the pre-development condition by utilizing the existing retention basin. Riverside County Flood Control District and Water Conservation District requires that the difference in runoff hydrograph volume between the “post-developed” condition and the “pre-developed” condition for the 100hr-24hr storm frequency must be detained on-site. The rainfall volume for the pre-developed condition is 55, 837 C.F. for drainage area EX-A. The post developed rainfall volume is 95,590 C.F. for drainage area P-A. Hence, the difference in pre and post developed runoff volume is 39,753 C.F. Meanwhile, per the M-WQMP the prorated volume provided by the existing retention basin was calculated to be 51,183 C.F. for Retention Basin D, which is adequate to meet flood control requirements. Furthermore, it was noted that the pre-development peak flow was 7.98 cfs, compared to the total post-development peak flow of 17.32 cfs at 100yr-24hr storm frequency. Lastly, it has been determined that the proposed storm drain system can convey runoff generated at 100-year storm events. Therefore, the proposed development meets the WQMP and flood requirements for this project and will not result in an adverse effect to the community.

Municipal Code
Section 13.16.110
To minimize the discharge and transport of pollutants, the city requires all new development and redevelopment projects identified as a Priority Project under the newly implemented NPDES permit No. CAS617002 to retain 100% of the stormwater from the 100 year, 24-hour duration storm in order to prevent any deterioration of the water quality which would impair the subsequent or competing uses of water. Projects that retain and infiltrate 100% of the rainfall conditions specified in Section F.1.c.v.4 of the NPDES permit are deemed to comply with the Treatment Control BMP requirements found in that section of the NPDES permit. The NPDES permit establishes acceptable methods and standards for controlling stormwater runoff volumes, rates, and pollutant loading including but not limited to the following:

A. Increase Permeable Areas, Avoid placing impervious surfaces in highly porous soil areas; incorporate landscaping and open space into the project design; use porous materials for or near driveways and walkways; incorporate retention basins that can infiltrate Stormwater onsite; and avoid placing pavement and other impervious surfaces in low lying areas.

B. Direct Runoff to Permeable Areas. Direct Stormwater runoff away from impermeable areas to swales, berms, green strip filters, gravel beds, and French drains; install rain gutters and orient them toward permeable areas; modify the grade of the property to divert flow to permeable areas and minimize the amount of stormwater runoff leaving the property and when designing curbs, berms and other structures, avoid designs which isolate permeable or landscaped areas.

C. Maximize Stormwater Storage for Reuse. Use retention structures, surface areas, cisterns, or other structures to store stormwater Cathedral City Municipal Code – Title 8 §

8.24.070
A. Except as noted below, development of all land within the city must include provisions for the management of stormwater runoff from the property which is to be developed. This management shall consist of constructing stormwater storage facilities, which includes detention basins. As a minimum, all development will make provisions to store runoff from rainfall events up to and including the one-hundred-year, three-hour duration event.

If a suitable outlet for a detention basin is not available, or if engineering analysis indicates that available outlet systems would be overtaxed by detention basin outflow, a retention basin shall be constructed in lieu of a detention basin.

B. The requirement for construction of a detention basin or a retention basin may be waived in the following cases:

1. The runoff has been included in a storage facility at another location. This may include storage facilities proposed as part of the Cathedral City Storm Drain Master Plan;

2. An application for a building permit to construct a single-family residential structure;

3. Development which will drain directly into a floodway or watercourse drainage channel which has been determined by the project review manager, using engineering analyses provided by the development, to have the capacity and be constructed to handle the additional runoff flow without increasing the potential for flood damage on any other downstream property.

4. Development of a parcel under one-half acre in an area where it can be demonstrated by engineering analyses that no significant increase in the potential for flood damage will be created by the development.
