Re: Energy Measurement for Dynamic Penetrometers
Standard Penetration Test (SPT) on Truck 170 CME 75 drill rig Fresno, CA. GRL Job No. 228076-1
Dear Mr. Allen Bushey:

This report transmits our findings from energy measurements and related data analysis conducted by GRL Engineers, Inc. (GRL) for your Truck 170 mounted CME 75 drill rig located Fresno, CA.

One automatic hammer and penetrometer system was monitored during Standard Penetration Test (SPT) of the test borehole BH2. Dynamic testing summarized in this report was conducted on June 2, 2022.

The purpose in collecting the SPT energy measurements was to compute the energy transfer efficiency for a single SPT hammer. To meet this objective, an 8G Model, Pile Driving Analyzer® (PDA) utilizing the SPT Analyzer feature was used to acquire and process the dynamic test data.

Additional information regarding the testing equipment and analytical procedures is provided in Appendix A.

Test Sequence
Using an instrumented AW-J rod for a Truck 170 mounted CME 75 drill rig at test borehole BH2, energy measurements were made at five sample depths for the drill rig. From BH2, the dynamic measurements were obtained from sample depths of 10.0, 12.5, 14.5, 18.0 and 20.0 ft. Each sample depth consisted of energy measurements of 18 inches of driving.

Energy Transfer Measurements
A Model 8G Pile Driving Analyzer was used to take measurements of strain and acceleration.

The strain and acceleration signals were conditioned and converted to forces and velocities by the PDA. The PDA interprets the measured dynamic data according to the Case Method equations. Force and velocity records from the PDA were also viewed graphically on an LCD screen to evaluate data quality. All force and velocity records were also digitally stored for subsequent analysis.

The maximum energy transferred to the rod (EMX) was calculated by integrating both the force and velocity records over time as follows:

EMX = ∫F(t)V(t)dt
Where: F(t) = the force at time t
V(t) = the velocity at time t
The energy transfer ratio or efficiency is computed by dividing EMX by the theoretical SPT hammer energy of 350 lb-ft (computed from the product of the hammer weight, assumed to be the standard 140 lbs, and the fall height, assumed to be 2.5 ft). The SPT N values can then be corrected for a nominal 60% transfer efficiency, N60, as follows:

N60 = (em / 60) Nm
Where: em = the measured transfer ratio (ETR)
Nm = the measured SPT “N” value
Conclusions
Table 1 in Appendix B presents a summary of the average transferred energy and the energy transfer ratio for the single drill rig at each sample depth calculated using the EMX equation.

Included in Table 1 are also average values of the hammer operating rate, maximum impact force and maximum velocity of the rod. The overall performance, which represents the average of data from all sample depths for each rig/rod type is also shown. Complete data, including the maximum, minimum and standard deviation for each sampling depth, is included in Appendix B.

For the Truck 170 mounted CME 75 drill rig at BH2, the average energy transfer ratio from individual sample depths ranged from 84.0% to 104.5%.

The average, overall transfer ratio (for all sampling depths weighted by N-values for each sample) were as follows:

SPT Rig (Serial Number) Overall Transfer

Rate (BPM)

APPENDIX A

AN INTRODUCTION INTO SPT DYNAMIC PILE TESTING
The following has been written by GRL Engineers, Inc. and may only be copied with its written permission.

1. BACKGROUND
The Standard Penetration Test is frequently
conducted as an in-situ assessment of soil strength.

This test requires that a 140 lb weight is dropped 30
inches onto a drive rod at whose bottom a sampler is
usually installed. The sampler is driven for 18 inches; the number of blows required for the last 12 inches of
driving is the so-called N-value. The N-value may be
used as a strength indicator for foundation design or
as a means of assessing the liquefaction potential of
soils.

Obviously, the SPT hammer efficiency is an important
consideration when using the N-values for design
purposes. Measurements have indicated that the
energy in the drive rod is sometimes only 30% and
and may reach 90% of the potential or rated energy of
the SPT hammer (E-rated = 0.35 kip-ft or 0.475 kJ).

The type of hammer used to drive the rod is the main
reason for these variations. On the average, the
energy in the drive rod is 60% of the standard rated
energy.

Because of the variability of energy, methods based
on N-values are considered unreliable. However,
measurements during SPT testing using the Case
Method can be done on a routine basis and these
measurements yield the transferred energy values.

With measured energy, EMX, known, an adjustment
of the measured N-value, Nm, can be made as follows.

N60 = Nm [Em / (0.6Er )] (1)
Thus, if the measured energy value is equal to the
normally expected transferred energy of 60% of Erated then the adjusted and measured N-values are identical. On the other hand, if the measured energy
is only 30% then the adjusted blow count will be
reduced by 50%.

2. DYNAMIC TESTING AND ANALYSIS

METHODS APPLIED TO SPT
The Case Method of dynamic pile testing, named after
the Case Institute of Technology where it was
developed between 1964 and 1975, requires that a
substantial ram mass (e.g. a pile driving hammer)
impacts the pile top such that the pile undergoes at
least a small permanent set. Thus, the method is
also referred to as a “High Strain Method”. The Case
Method requires dynamic measurements on the pile
or shaft under the ram impact and then a calculation
of various quantities. Conveniently, for SPT
applications, the measurements and analyses are
done by a single piece of equipment: the SPT
Analyzer. The Pile Driving Analyzer® (PDA) is also
suitable to perform these measurements and data
processing.

A related analysis method is the “Wave Equation
Analysis” which calculates a relationship between
bearing capacity, pile stresses, transferred energy
and field blow count. The GRLWEAP™ program
performs this analysis and provides a complete set
of helpful information and input data. This program
can be used very effectively to simulate the SPT
driving process.

3. MEASUREMENTS
GRL uses equipment manufactured by Pile
Dynamics, Inc. The system includes either an SPTAnalyzer™ (SPTA) or a Pile Driving Analyzer® (PDA), an instrumented rod section and two
accelerometers. SPT energy testing is very closely
related to and borrows procedures from dynamic pile
testing. Those interested in the basis of the SPT
energy testing method may obtain extensive
literature on dynamic pile testing from GRL
Engineers, Inc.

3.1 SPT Analyzer or Pile Driving Analyzer
The basis for the results calculated by the SPTA or
PDA are strain and acceleration measured in an
instrumented rod section. These signals are
converted to rod top force, F(t), and rod top velocity, v(t). The SPTA or PDA conditions, calibrates and
displays these signals and immediately computes
average pile force and velocity thereby eliminating
bending effects. The product of these two

22.263
A-2
measurements is then integrated over time which
yields the energy transferred to the instrumented
section as a function of time (see Section 4.1).

For convenience and accuracy, strain measurements
are usually taken on an instrumented section of SPT
drive rod. Ideally, the section properties of the
instrumented rod and those of the drive rod are the
same, however, using subs, other sections can also
be utilized.

For the instrumented section, PDI provides a force
calibration in such a way that the output of the
instrumented rod is directly calculated without the
need for an accurate elastic modulus or cross
sectional area of the rod section.

The acceleration measurements are often demanding
in the SPT environment, because of high frequency
and high acceleration motion components. An
experienced measurement engineer, therefore, has to
evaluate the quality of this data before final
conclusions are drawn from the numerical results
calculated by SPTA or PDA.

SPTA or PDA records are taken while the standard Nvalue is acquired in the conventional manner. This then allows a direct correlation between N-value and
average transferred energy.

3.2 HPA
The SPT hammer’s ram velocity may be directly
obtained using radar technology in the Hammer
Performance Analyzer™. The impact velocity results
can be automatically processed with a PC or recorded
on a strip chart. HPA measurements yield a hammer
kinetic energy, but not the energy transferred to the
drive rod.
4 RECORD EVALUATION BY SPTA OR PDA

4.1 HAMMER PERFORMANCE
The PDA calculates the energy transferred to the pile
top from:

E(t) = oIt
F(J)v(J) dJ (2)
The maximum of the E(t) curve is often called
ENTHRU or EMX; it is the most important quantity for
an overall evaluation of the performance of a hammer
and driving system. EMX allows for a classification of
the hammer's performance when presented as, eT,
the rated transfer efficiency, also called energy
transfer ratio (ETR) or global efficiency.
eT = EMX/ER (3)
where ER is the hammer manufacturer’s rated
energy value or 0.35 kip-ft (0.475 kJ) in the case of
the SPT hammer.

Often in the SPT literature one finds also reference
to the EF2 energy. This evaluation is based on
assumed proportionality between force and velocity
(see also Section 5):
v(t) = F(t) / Z (4)
where Z = EA/c is the pile impedance, E is the elastic
modulus, A is the cross sectional area and c is the
speed of the stress wave in the pile material..

Combining equations 2 and 4 leads to
EF(t) = oIt
F(J)
2 / Z dJ (5)
The EF2 transferred energy value is the EF-value at
the time t = 2L/c, where L is the drive rod length and
c is the stress wave speed in steel (16,800 ft/s or
5,124 m/s). Since the force is easier to measure than
both force and velocity, Equation 5 is preferred by
some test engineers. However, the EF method is
fraught with errors and certain correction factors
have to be applied to make it approximately correct.

Among the error sources are the following:
• Proportionality is often violated prior to time
2L/c. The proportionality between force and
velocity in a downward traveling wave only
holds if the wave does not encounter a
disturbance prior to reflecting off the pile toe.

Such disturbances include a change in cross
sectional area, an open or loose splice or joint,
or resistance along the shaft.
• Using only one force measurement precludes
a data quality check based on the
proportionality between force and velocity.

Thus, a force measurement that is for some
reason in error may not be detectable, which
will lead to errors in the EF2 value. Data
quality checks will be discussed further in
Section 5.

22.264
A-3
The use if EF2 is therefore not recommended but it is
often included in result presentations for the sake of
completeness.

4.2 STRESSES
During SPT monitoring, it is also of interest to monitor compressive stresses at both the top of the drive rod
and at its bottom.

At the pile top (location of sensors) the maximum
compression stress averaged over the rod’s cross
section, CSX, is directly obtained from the
measurements. Note that this stress value refers to
the instrumented section. If the rod has a different
cross sectional area then the stress in the rod will be different from CSX.

The SPTA or PDA can also calculate, in an
approximate manner, the force at the rod bottom,
CFB. To obtain the corresponding stress, this force
value should be divided by the appropriate cross
sectional area, e.g. by the rod area just above the
sampler or by the sampler area itself. Of course, nonuniform stress components as they might occur at the sampler tip due to a sloping rock are not considered
in this calculation.

5. DATA QUALITY CHECKS
Quality data is the first and foremost requirement for
accurate dynamic testing results. It is therefore
important that the measurement engineer performing
SPTA or PDA tests has the experience necessary to
recognize measurement problems and take
appropriate corrective action should problems
develop. Fortunately, dynamic pile testing allows for
certain data quality checks because two independent
measurements are taken that have to conform to the
so-called proportionality relationship.

As long as there is only a wave traveling in one
direction, as is the case during impact when only a
downward traveling wave exists in the rod, force and
velocity measured at its top are proportional
F = v Z (5)
where Z is again the pile impedance, Z = EA/c. This
relationship can also be expressed in terms of stress
F = F/A = v (E/c) (6)
or strain
, = F/E = v / c (7)
This means that the early portion of strain times
wave speed must be equal to the velocity unless the
proportionality is affected by high friction near the
pile top or by a pile cross sectional change not far
below the sensors. Checking the proportionality is
an excellent means of assuring meaningful
measurements but is only truly meaningful for
perfectly uniform rods. Open or loose splices, for
example, will lead to a non-proportionality. For SPT
rods it is fortunate that usually no soil resistance acts along the shaft and for that reason, proportionality
can exist until the stress wave returns from sampler
top or rod bottom unless connectors are not
sufficiently tightened or have a significant mass.

Velocity data quality can also be checked by looking
at the final displacement, DFN, which is calculated
from the acceleration by double integration. If the
calculated final displacement is much higher or lower
than indicated by the N-value, the accelerometer
attachment may be loose or the sensor may be
faulty. If major drift in the velocity is observed, the EMX value may be in error, even though
proportionality from impact to time 2L/c exists. In this case, it may be useful to evaluate the energy
transferred to the drill rod at time 2L/c, which is
calculated by the PDA or SPTA as the E2E quantity.

PHASE I ENVIRONMENTAL SITE ASSESSMENT

SANTA CRUZ CITY SCHOOLS
313 SWIFT STREET
SANTA CRUZ, CALIFORNIA 95060

EXECUTIVE SUMMARY
Moore Twining Associates, Inc. (Moore Twining) was retained by Santa Cruz City Schools (SCCS) to conduct a Phase I Environmental Site Assessment (Phase I ESA) for a property located at 313 Swift Street in Santa Cruz, California (Subject Property). This Phase I ESA was conducted in conformance with the methods and procedures described in the American Society for Testing and Materials (ASTM) “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process” (E1527-21), published November 2021 and adopted February 13, 2023.

This summary should be used in conjunction with the entire report. It should be recognized that details were not included or fully developed in this section, and the report must be read in its entirety for a comprehensive understanding of the Subject Property history and conditions. Please review the entire report for more information regarding Moore Twining’s findings and opinions.

Subject Property
The Subject Property is comprised of approximately 3.45 acres of a 4.08 acre parcel developed with an asphalt concrete paved driveway/cul-de-sac with Portland cement concrete (PCC) sidewalks. The Subject Property is located at 313 Swift Street in the city of Santa Cruz, California. The Subject Property has been assigned the following Santa Cruz County Assessor’s Parcel Number (APN): 003-161-32.

At the time of the Subject Property reconnaissance, the Subject Property consisted of an asphalt concrete paved driveway/cul-de-sac with PCC sidewalks down the north and central portion of the Subject Property. The northwest corner of the Subject Property was used for storage with multiple metal storage/shipping containers ranging in size from about 20 to 40 feet long by about 8 feet wide. The remainder of the Subject Property was open field and grass covered areas.

Based on Moore Twining’s review of historical aerial photographs, city directories, topographic maps and Sanborn maps, the Subject Property was vacant, undeveloped land until the late 1920’s/early 1930’s. During the early 1930’s to the early 1940’s, row crops were grown on the Subject Property. By 1968, the Subject Property was developed with two structures and paved driveway and parking areas. The Subject Property was redeveloped in approximately 2005, and the two prior structures were removed and replaced with five (5) new buildings constructed across the Subject Property (Note: at the time of the Subject Property reconnaissance, three (3) of the five (5) structures had been removed/demolished.) The Subject Property was identified on numerous databases in the EDR report, and a ‘No Further Action’ cleanup case was identified on the DTSC EnviroStor website. A Phase I ESA was conducted on the Subject Property in December 2000, and identified one REC associated with the past uses of the Subject Property.

22.292
Santa Cruz City Schools, Santa Cruz, California- Phase I ESA E95815.02 June 21, 2023 Page ii
The Subject Property was historically used by the National Guard Armory, and vehicle and tank maintenance were conducted on the Subject Property. A limited soil and groundwater assessment was recommended. In May 2002, a Preliminary Endangerment Assessment (PEA) was conducted to address the concerns associated with the former National Guard Armory activities. Elevated concentrations of some PAHs were identified in the vicinity of the former grease rack, but no other constituents of concern (COCs) were identified above their respective screening levels at that time. No further action was recommended and approved by Department Toxic Substances Control (DTSC) in July 2002.

Off-Subject Property
Based on Moore Twining’s review of historical aerial photographs, city directories, topographic maps and Sanborn maps, the adjoining properties to the north, west and south were undeveloped until the early 1930’s, through the early 1940’s, when the properties were used for row crops. To the east, across Swift Street, were residential homes. By the late 1960’s, a school is present to the south and commercial structures are present to the north as well. Additional residential homes are present to the east. By the mid 1970’s, residential homes are present to the southwest and to the west is a commercial building. By the 1980’s, multiple commercial and apartment buildings are present to the north of the Subject Property.

At the time of the Subject Property reconnaissance, the Subject Property was bordered to the westnorthwest and north by multi-family residential buildings; to the east by Swift Street, followed by singlefamily residential; to the south by a school, and to the southwest by a park.

Based on Moore Twining’s review of readily available documents on the GeoTracker and EnviroStor websites, and information provided in the EDR database report, one off-Subject Property facility was identified as a potential environmental concern for the Subject Property. Santa Cruz Industries, located approximately 640 feet to the north of the Subject Property, is an active cleanup case with the Regional Water Quality Control Board (RWQCB). The facility is currently in a ‘verification monitoring’ phase, and soil gas investigations are currently ongoing.

Conclusion Summary
On behalf of Santa Cruz City Schools, Moore Twining performed a Phase I Environmental Site Assessment in conformance with the scope and limitations of ASTM E1527-21 for Santa Cruz City Schools property located at 313 Swift Street in the city of Santa Cruz, California. This assessment has revealed the following:

Recognized Environmental Conditions
Based on Moore Twining’s review of historical documents for the Subject Property, the past uses of the Subject Property as a National Guard Armory/Military Police Depot with a garage and concrete ramp for vehicle/tank maintenance/repairs is a REC. A PEA conducted in 2002 identified several COCs with elevated concentrations in the vicinity of the former grease rack, but concentrations were deemed to be typical of those found in ‘urban environments’ and no further action was recommended; DTSC agreed and approved the PEA in July 2002.

22.293
Santa Cruz City Schools, Santa Cruz, California- Phase I ESA E95815.02 June 21, 2023 Page iii
Findings from this assessment and a concurrent geotechnical engineering subsurface investigation found groundwater to be at depths ranging from 3 to 6 feet below ground surface, and olfactory observations of petroleum hydrocarbon contamination in the central portion of the Subject Property. Additionally, a review of historical documents for the nearby Santa Cruz Industries facility, located at 411 Swift Street, indicate that monitoring well MW-18, which is located on the Subject Property, has historically had elevated concentrations of TCE above the CalEPA RSLs. Based on these findings, it is our opinion, further soil, groundwater and soil vapor assessment is warranted.

Controlled Recognized Environmental Condition
No CRECs were identified during the course of this assessment.

Historical Recognized Environmental Condition
No HRECs were identified during the course of this assessment.

Proposed Additional Investigations
Based on a review of historical documentation, the Subject Property and vicinity have continually been used for agricultural purposes. The legal application of agricultural chemicals is not considered a REC by the Comprehensive Environmental Response, Compensation and Liability (CERCLA) act of 1980. The exemption in noted in (4) Application of Pesticides – Section 107(i) of the ASTM 1527- 21 standard. However, a clause is noted in the exemption stating, “The pesticide exemption also contains a ‘savings clause” that provides that the cost recovery prohibition does not alter or modify any obligations or liability under any other federal or state law for damages, injury or loss resulting from a release of hazardous substances, or for the costs of removal or remedial actions of such hazardous substances.” It has been Moore Twining’s experience that persistent pesticides can exist in soils after long-term use of agricultural chemicals. From the historical documents researched, no information was discovered that would indicate illegal agricultural activities occurred at the Subject Property. As the Subject Property was used from the 1930’s to 1940’s for agricultural purposes, the potential exists that persistent pesticides and other related agricultural chemicals may be present in the soils at the Subject Property. These constituents, even in low concentrations, can result in federal, state and local requirements for movement, disposal, assessment, and remediation. If present, costs could be incurred to address these conditions.

1.0 INTRODUCTION
Moore Twining Associates, Inc. (Moore Twining) was retained by Santa Cruz City Schools (SCCS) to conduct a Phase I Environmental Site Assessment (Phase I ESA) for a property located at 313 Swift Street in Santa Cruz, California (Subject Property). This Phase I ESA was conducted in conformance with the methods and procedures described in the American Society for Testing and Materials (ASTM) “Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process” (E1527-21), published November 2021 and adopted February 13, 2023.

1.1 Objective
The objective of this assessment was to identify Recognized Environmental Conditions (RECs) located at the Subject Property or adjacent properties that could present material risk of harm to public health or to the environment. Recognized Environmental Conditions are defined in ASTM E1527-21 as:
 Recognized Environmental Conditions (RECs) - the presence of hazardous substances or petroleum products in, on, or at the Subject Property due to a release to the environment; (2) the likely presence of hazardous substances or petroleum products in, on, or at the Subject Property due to a release or likely release to the environment; or (3) the presence of hazardous substances or petroleum products in, on, or at the Subject Property under conditions that pose a material threat of a future release to the environment.
 Controlled Recognized Environmental Conditions (CRECs) – recognized environmental condition affecting the Subject Property that has been addressed to the satisfaction of the applicable regulatory authority or authorities with hazardous substances or petroleum products allowed to remain in place subject to implementation of required controls (for example, activity and use limitations or other property use limitations).
 Historical Recognized Environmental Conditions (HRECs) – a previous release of hazardous substances or petroleum products affecting the Subject Property that has been addressed to the satisfaction of the applicable regulatory authority or authorities and meeting unrestricted use criteria established by the applicable regulatory authority or authorities without subjecting the Subject Property to any controls (for example, activity and use limitations or other property use limitations).

1.2 Scope of Services
This Phase I ESA was performed to evaluate the potential presence of environmental conditions that may have resulted from operations at the Subject Property or at nearby properties. The assessment included a Subject Property reconnaissance, a review of available documentation of land-use history for evidence of the use, storage and/or disposal of hazardous substances, and a review of available regulatory information. This Phase I ESA included the following tasks:
• A review of the current and past uses of the Subject Property since 1928; • A Subject Property reconnaissance to assess evidence of current and/or past use or storage of toxic or hazardous material; on-Subject Property ponds, landfills, drywells,

22.295
Santa Cruz City Schools, Santa Cruz, California- Phase I ESA E95815.02 June 21, 2023 Page 2
waste streams or other disposal units; visible soil discoloration; aboveground or underground storage tanks; electrical transformers containing polychlorinated biphenyls (PCBs); and drums, barrels and other storage containers; • Visual observation of adjacent properties in order to determine if current and/or historical operations associated with these properties may pose a threat to the Subject Property;
• A review of available federal Environmental Protection Agency (EPA), state EPA and regulatory agency lists of known or potential hazardous waste sites or landfills, and sites currently under investigation for environmental violations in the Subject Property area.

Using area-profile services provided by Environmental Data Resources, Inc. (EDR), Moore Twining cataloged properties near the Subject Property that have been identified on regulatory agency lists. Search criteria were in conformance with ASTM E1527-21; • Contact with relevant municipal, county and state agencies to review readily available records and permits; and
• Preparation of this report to present our methods, findings and conclusions.

The Scope of Services specifically excluded cultural, archeological, and biological assessments, as well as sampling and analysis for the potential presence of asbestos containing building materials, lead based paint, or an assessment for radon gas. In addition, the Scope of Services did not include the collection and/or analysis of any materials including air, soil, soil-gas, or groundwater samples.

1.3 Limitations and Limited Conditions
The purpose of an environmental assessment is to reasonably assess the potential for, or actual impact of, past practices on a given Subject Property that may pose an environmental impairment to the Subject Property. No assessment is thorough enough to identify all potential environmental impairments at a given Subject Property. If environmental impairments have not been identified during the assessment, such a finding should not, therefore, be construed as a guarantee of the absence of such conditions on the Subject Property, but rather the result of the services performed within the scope, limitations, and cost of the work performed.

The conclusions presented in this report are solely professional opinions based on information provided regarding the Subject Property and the findings of the reconnaissance and records search. Information obtained from the aerial photography is an interpretation of features observed in the photographs. Actual conditions at the Subject Property may have been different from those interpreted. Conclusions presented are based on conditions as they existed at the time the work was performed. Changes in existing conditions of the Subject Property due to time lapse, natural causes, or operations adjacent to the Subject Property may deem conclusions presented in this Phase I ESA report invalid, unless the changes are reviewed, and the conclusions reevaluated. Such conditions may require additional reconnaissance of the Subject Property and require field exploration and laboratory testing to assess if the conclusions are applicable considering the changed conditions.

content left in the drums. The drums were not labeled. Numerous 5-gallon buckets were located in the northwest corner of the Subject Property as well. The 5-gallon buckets contained paint, roof patch; some of the buckets were unlabeled or the label was so worn the labels could not be read.

Hazardous or Petroleum Waste Streams: Personal size, 2- to 5-gallon size, gas cans were observed in the storage containers on the Subject Property.

Stained Soil or Pavement: Staining was observed on the wood floors of the storage/shipping containers (about 20 to 40 feet long by about 8 feet wide) on the Subject Property.

Trash, Debris, and/or Other Waste Materials: The northwest corner of the Subject Property, in the vicinity of the storage/shipping containers, had become a staging area for construction-type debris and waste, including various types of piping, vaults/manhole covers, yard tools, pallets, bricks, fencing, flooring materials, paint cans/buckets, personal size household cleaners, etc. Additionally, some yard waste has been staged in this area as well.

Other Specific Indicators of Environmental Conditions
Moore Twining was concurrently performing a geotechnical engineering investigation on the Subject Property. During drilling activities on the central portion of the Subject Property, strong petroleum hydrocarbon odors were noted in three (3) soil borings that were advanced to depths of approximately 18 feet below ground surface (bgs). No soil samples were collected for laboratory analysis at the time of Moore Twining’s geotechnical engineering investigation, but additional assessment is warranted in the vicinity of these borings to further investigate the vertical and lateral extent of contamination, and the concentrations of the COCs.

4.0 HISTORICAL LAND USE
The history of land-use on and near the Subject Property was determined from the review of historic aerial photographs, topographic maps, Sanborn maps, building permits, and historic city directories. The findings are summarized in the following subsections.

4.1 Aerial Photograph Review
Available historical aerial photographs of the Subject Property and vicinity for the years 1928, 1931, 1940, 1943, 1956, 1968, 1974, 1982, 1993, 2005, 2009, 2012, 2016, and 2020 were reviewed for indications of past Subject Property use and/or Subject Property activities which may have involved the manufacture, generation, use, storage, and/or disposal of hazardous materials. The results of the aerial photograph review are summarized in the following table. Copies of the historical aerial photographs are included in Appendix D of this report.

A copy of the EDR Environmental Lien and AUL Search is included in Appendix D of this report.

4.8 Summary of Past Uses of the Subject Property
Based on Moore Twining’s review of historical aerial photographs, city directories, topographic maps and Sanborn maps, the Subject Property was vacant, undeveloped land until the late 1920’s/early 1930’s. During the early 1930’s to the early 1940’s, row crops were grown on the Subject Property. By 1968, the Subject Property was developed with two structures and paved driveway and parking areas. The Subject Property was redeveloped in approximately 2005, and the two prior structures were removed and replaced with five (5) new buildings constructed across the Subject Property (Note: at the time of the Subject Property reconnaissance, three (3) of the five (5) structures had been removed/demolished.)

4.9 Summary of Past Uses of Adjoining Properties
Based on Moore Twining’s review of historical aerial photographs, city directories, topographic maps and Sanborn maps, the adjoining properties to the north, west and south were undeveloped until the early 1930’s, through the early 1940’s, when the properties were used for row crops. To the east, across Swift Street, were residential homes. By the late 1960’s, a school is present to the south and commercial structures are present to the north as well. Additional residential homes are present to the east. By the mid 1970’s, residential homes are present to the southwest and to the west is a commercial building. By the 1980’s, multiple commercial and apartment buildings are present to the north of the Subject Property.

5.0 USER PROVIDED INFORMATION

5.1 User Provided Information
This section summarizes information provided by the user that assisted in the identification of potential RECs associated with the Subject Property.

5.2 Environmental Questionnaires
Moore Twining submitted an Environmental Questionnaire to Mr. Trevor Miller, a representative of Santa Cruz City Schools. As of the date of this report, Moore Twining has not received the completed questionnaire back from Mr. Miller.

5.3 Previous Investigations
Moore Twining was not provided with any historical reports for the Subject Property from the property owner.

6.0 REGULATORY RECORDS REVIEW
Available federal, state and relevant county and municipal records for the Subject Property and pertinent properties within the Subject Property vicinity that have or potentially have had a release to the environment were reviewed as part of this assessment. The findings are summarized in the following subsections.

6.1 Agency File Review
Requests to review files for the Subject Property were submitted to the Regional Water Quality Control Board (RWQCB), the Department of Toxic Substances Control (DTSC), Santa Cruz County (SCC), and the City of Santa Cruz. Printouts and information from regulatory databases and agencies are included in Appendix C.

The RWQCB was unable to locate any records for the Subject Property. DTSC directed Moore Twining to their EnviroStor website.

Information regarding the Subject Property and nearby properties was additionally searched on the DTSC Envirostor website (http://envirostor.dtsc.ca.gov/, Envirostor), and the State Water Resource Control Board’s GeoTracker website (http://geotracker.waterboards.ca.gov/, GeoTracker). At the time this report was issued to the client, the Subject Property did not appear on the GeoTracker website. Two reports were identified for the Subject Property on the EnviroStor database, a Phase I Environmental Site Assessmenet and a Preliminary Endangerment Assessment Report.

6.1.1 Subject Property Investigations
A review of the EnviroStor database identified the following reports/documents:

22.305
Santa Cruz City Schools, Santa Cruz, California- Phase I ESA E95815.02 June 21, 2023 Page 12
Phase I Environmental Site Assessment Ark/Monarch School, 255 Swift Street, Santa Cruz, California, December 12, 2000 (WHA)
In December 2000, Weber, Hayes and Associates (WHA) prepared a Phase I ESA for the Santa Cruz City School District. Per interviews conducted during the Phase I, WHA learned the western portion of the Subject Property had a ramp which had been utilized by the National Guard for armored tank and truck maintenance purposes. WHA also located a groundwater monitoring well across the street from the Subject Property, which was later tied to an ongoing chlorinated solvent plume from the Santa Cruz Industries site, located approximately 500 feet to the north of the Subject Property. No other environmental concerns were identified.

Reportedly, WHA determined a limited soil and groundwater investigation was warranted in the vicinity of the ramp where vehicle maintenance was conducted.

Preliminary Endangerment Assessment Report, Ark/Monarch School Expansion, 313 Swift Street, Santa Cruz, California, May 2002 (Shaw)
Shaw Environmental and Infrastructure (formerly IT Corporation) (Shaw), conducted a Preliminary Endangerment Assessment (PEA), as required by DTSC. The PEA was prepared following guidance from the Preliminary Endangerment Assessment Guidance Manual (DTSC, 1994). The PEA was required to address five areas of concern:
 Existing grease rack (for metals, polycyclic aromatic hydrocarbons (PAHs), and total petroleum hydrocarbons (TPH);
 Suspected oil/water separator adjacent to the grease rack (metals, PAHs, and TPH);  Surface water swale (metals, PAHs, and TPH)
 Lead-based paint on the Independent Studies portable classroom building (lead)  Groundwater (chlorinated volatile hydrocarbons)
Eighteen (18) soil borings were advanced as part of the PEA, at depths ranging from 0.5 feet below ground surface to a depth of 6 feet bgs. Soil samples were collected around the grease rack/oil/water separator area, the surface water swale area and Independent Studies portable classroom. Additionally, three (3) soil gas samples were collected along the northern edge of the Subject Property.

Soil analytical results reported detectable concentrations of metals in each of the soil samples analyzed, at background levels, which were below the level of health concern (based on residential land use screening levels at that time). TPH as diesel (TPH-d) and motor oil (TPH-mo) were detected in half of the soil samples analyzed, at concentrations ranging from 1.5 milligram per kilogram (mg/kg) to 56 mg/kg TPH-d and 7.4 mg/kg to 270 mg/kg TPH-mo. TPH-d and TPH-mo concentrations were below the established San Francisco Bay Regional Water Quality Control Board 2002 screening levels. PAHs were

22.306
Santa Cruz City Schools, Santa Cruz, California- Phase I ESA E95815.02 June 21, 2023 Page 13
also detected in approximately half the soil samples analyzed, but at concentrations below their respective residential preliminary remediation goals (PRG), with the exception of the surface soil sample from GR-9. The surface soil sample from GR-9 exceeded the Preliminary Remediation Goasl (PRGs).

Based on the results of the soil sampling, a health risk screening was conducted. Analytical results from boring GR-9, which had the highest reported concentrations of constituents of concern, were used in the PEA algorithms. “The cumulative potential cancer risk is 2x10-5, which is above the de minimus level of 1x10-6. The risk is associated primarily with the maximum concentrations of benzo(a)pyrene (risk of 1x10- 5 ) and dibenzo(a,h)anthrancene (risk of 5x10-6) that were found in sample GR-9. No further action is recommended for this site because the elevated levels of PAHs are restricted to the surface soil in one spot near the grease rack…Further, the PAH levels detected in GR-9-0 are comparable to the low end of the concentrations reported for urban soils. Thus, risks from the site are comparable to most urban environments.”
Reportedly, based on the results of the soil sampling, soil gas sampling and health risk screening, Shaw recommended no further action for the Subject property.

6.1.2 Off-Subject Property Investigations
A review of the GeoTracker/EnviroStor database identified the following off-Subject Properties of concern:

Santa Cruz Industries (SLT3S0011280): 411 Swift Street, Santa Cruz, California Per the Trinity Source Group, Inc. (Trinity) Source Area Data Gaps Investigation Report and Remedial Action Plan, dated May 25, 2018, the facility history “…was a retail display manufacturer that operated a metal plating facility at the Site for approximately 34 years. Metal plating operations were reportedly discontinued in October 1988 and retail display manufacturing ceased operations in 1999. The Site has been impacted by elevated concentrations of several halogenated volatile organic compounds (HVOCs), particularly tetrachloroethene (PCE) and its degradation products; 1,1,1-Trichloroethane (1,1,1-TCA); and 1,4-Dioxane in soil, soil gas, and groundwater. The Site has undergone a series of investigations and remediation attempts, with limited success.

Since the 1990’s, a plume of HVOCs was identified in perched groundwater beneath the property and at offsite areas to the southeast. The HVOC contamination is likely a result of onsite painting and vapor degreasing activities in the Southern Building (Figure 2). A former spray paint booth was located in the northwest corner of the former painting area and was removed in 1991. A PCE and 1,1,1-TCA vapor degreasing tank was utilized in this area. Degreasing fumes were reportedly discharged through a vent to the exterior along the alley between the Northern and Southern buildings (Figure 2).

Since discovery of the contamination, multiple remediation events have been performed in various portions of the plume3
. The remediation activities have included soil gas extraction, subsurface injections of RegenOx, 3DMe, hydrogen-releasing compound, and persulfate with sodium hydroxide

22.307
Santa Cruz City Schools, Santa Cruz, California- Phase I ESA E95815.02 June 21, 2023 Page 14
activator4
. Despite remediation attempts, HVOC (specifically PCE) contamination in groundwater persists at concentrations indicative of a dense, non-aqueous phase liquid (DNAPL). 3 Based on available information, remedial activities were limited to the Southern building and parking lot along Delaware Avenue.
4 Historical monitoring results, as well as full discussions of all previous Site activities, are contained in reports posted to GeoTracker.”
In 2022, Trinity continued remediation activities on the Site with the startup of an Electrical Resistance Heating (ERH) remediation system. Prior to the startup of this ERH system, in April 2022, a baseline groundwater monitoring event was performed. As a result of the monitoring event, the Central Coast-RWQCB requested a off-site soil gas investigation. The workplan for this additional assessment was submitted in July 2022, and the second addendum was approved in December 2022. No reports or documentation has been submitted regarding the proposed off-site soil gas investigation. Numerous reports and updates have been uploaded to the GeoTracker database regarding the ERH system status and the monthly operation and maintenance reports.

A review of historical documents for the Santa Cruz Industries property identified one monitoring well, MW-18, to be on the Subject Property. Monitoring well MW-18 was installed in 1997, and was typically sampled once per year until December 2019. Detectable concentrations of trichloroethylene and cis-1,2-dichloroethene (cis-1,2-DCE) had been reported in 2018, but analytical results were below the laboratory detection limit in 2019. It does not appear this monitoring well has been sampled since 2019.

6.2 Environmental Database Review
Moore Twining contracted EDR to perform a search of available federal, state, and local database information systems for identifying known recognized environmental conditions present on the Property and nearby properties that have the potential to adversely impact the Subject Property being assessed in this study. EDR’s findings are summarized below. The complete report furnished by EDR is included in Appendix D of the report.

6.2.1 On-Subject Property
The Subject Property was listed on ENVIROSTOR database in the EDR report. The EnviroStor listing is associated with Phase I ESA and Preliminary Environmental Assessment (PEA) which were conducted on

22.309
Santa Cruz City Schools, Santa Cruz, California- Phase I ESA E95815.02 June 21, 2023 Page 16
the Subject Property during the school districts redevelopment of the property. The Phase I ESA and PEA were further discussed in Section 6.1.1 of this report.

6.2.2 Off-Subject Property
Moore Twining’s review of the referenced databases also considered the potential or likelihood of contamination from adjoining and nearby properties impacting the Subject Property. To evaluate which of the adjoining and nearby properties identified in the regulatory database report present an environmental risk to the Subject Property, Moore Twining considered the following criteria:
 The type of database on which the property is identified;  The topographic position of the property relative to the Subject Property;  The direction and distance of the site from the Subject Property;  Local soil conditions in the area of the Subject Property;  The known or inferred groundwater flow direction;
 The status of the respective regulatory agency-required investigation(s) of the identified site, if any; and
 Surface and subsurface obstructions and diversions (e.g., buildings, roads, sewer systems, utility service lines, rivers, lakes and ditches) located between the site and the Subject Property.

The following table lists the nearest reported offsite listings. Only those properties that were judged to present a potential environmental risk to the Subject Property and/or warrant additional clarification were further evaluated on the following table.

7.0 SUMMARY OF FINDINGS AND OPINIONS
The findings of the Phase I ESA are summarized in the following sections:

7.1 Subject Property
The Subject Property is comprised of approximately 3.45 acres of a 4.08 acre parcel developed with an asphalt concrete paved driveway/cul-de-sac with Portland cement concrete (PCC) sidewalks. The Subject Property is located at 313 Swift Street in the city of Santa Cruz, California. The Subject Property has been assigned the following Santa Cruz County Assessor’s Parcel Number (APN): 003-161-32.

At the time of the Subject Property reconnaissance, the Subject Property consisted of an asphalt concrete paved driveway/cul-de-sac with PCC sidewalks down the north and central portion of the Subject Property. The northwest corner of the Subject Property was used for storage with multiple metal storage/shipping containers ranging in size from about 20 to 40 feet long by about 8 feet wide. The remainder of the Subject Property was open field and grass covered areas.

Based on Moore Twining’s review of historical aerial photographs, city directories, topographic maps and Sanborn maps, the Subject Property was vacant, undeveloped land until the late 1920’s/early 1930’s. During the early 1930’s to the early 1940’s, row crops were grown on the Subject Property. By 1968, the Subject Property was developed with two structures and paved driveway and parking areas. The Subject Property was redeveloped in approximately 2005, and the two prior structures were removed and replaced with five (5) new buildings constructed across the Subject Property (Note: at the time of the Subject Property reconnaissance, three (3) of the five (5) structures had been removed/demolished.)

The Subject Property was identified on numerous databases in the EDR report, and a ‘No Further Action’ cleanup case was identified on the DTSC EnviroStor website. A Phase I ESA was conducted on the Subject Property in December 2000, and identified one REC associated with the past uses of the Subject Property.

The Subject Property was historically used by the National Guard Armory, and vehicle and tank maintenance was conducted on the Subject Property. A limited soil and groundwater assessment was recommended. In May 2002, a Preliminary Endangerment Assessment (PEA) was conducted to address the concerns associated with the former National Guard Armory activities. Elevated concentrations of some PAHs were identified in the vicinity of the former grease rack, but no other constituents of concern (COCs) were identified above their respective screening levels at that time. No further action was recommended and approved by DTSC in July 2002.

7.2 Off-Subject Property
Based on Moore Twining’s review of historical aerial photographs, city directories, topographic maps and Sanborn maps, the adjoining properties to the north, west and south were undeveloped until the early 1930’s, through the early 1940’s, when the properties were used for row crops. To the east, across Swift Street, were residential homes. By the late 1960’s, a school is present to the south and commercial structures are present to the north as well. Additional residential homes are present to the east. By the

22.312
Santa Cruz City Schools, Santa Cruz, California- Phase I ESA E95815.02 June 21, 2023 Page 19
mid 1970’s, residential homes are present to the southwest and to the west is a commercial building. By the 1980’s, multiple commercial and apartment buildings are present to the north of the Subject Property.

At the time of the Subject Property reconnaissance, the Subject Property was bordered to the westnorthwest and north by multi-family residential buildings; to the east by Swift Street, followed by singlefamily residential; to the south by a school, and to the southwest by a park.

Based on Moore Twining’s review of readily available documents on the GeoTracker and EnviroStor websites, and information provided in the EDR database report, one off-Subject Property facility was identified as a potential environmental concern for the Subject Property. Santa Cruz Industries, located approximately 640 feet to the north of the Subject Property, is an active cleanup case with the RWQCB.

The facility is currently in a ‘verification monitoring’ phase, and soil gas investigations are ongoing.

Additionally, monitoring well MW-18, which is part of the monitoring well network for the Santa Cruz Industries facility, is located on the Subject Property, and has not been sampled and recently, but, as of 2018, concentrations of trichloroethene (TCE) were above the California Environmental Protection Agency (CalEPA) Regional Screening Levels (RSLs).

7.3 Data Gaps, Limitations, and Deviations
Data gaps are described as a lack of or inability to obtain information required by the standards and practices listed in ASTM E1527-21, despite good faith efforts by the environmental professional or prospective landowner.

At the time this report was issued to the client, the completed environmental questionnaire that had been issued to Mr. Trevor Miller had not been returned to Moore Twining. It should be noted that in order to qualify for one of the Landowner Liability Protections (LLPs) offered by the Small Business Liability Relief and Brownfield’s Revitalization Act of 2001 (the “Brownfield’s Amendments”), the User must provide certain information (if available) identified in the User Questionnaire to the environmental professional.

Failure to provide this information could result in a determination that an “all appropriate inquiry” was not completed. As a result, this is considered a significant data gap and a deviation from the standard.

Chain of title information was not provided by the client. This is considered a data gap.

The material content of this report is intended to be consistent with a standard of practice as defined by ASTM E1527-21. However, the report format differs in style, arrangement, and presentation of material facts from the format described by ASTM.

8.0 CONCLUSIONS
On behalf of Santa Cruz City Schools, Moore Twining performed a Phase I Environmental Site Assessment in conformance with the scope and limitations of ASTM E1527-21 for Santa Cruz City Schools property located at 313 Swift Street in the city of Santa Cruz, California. This assessment has revealed the following:

22.313
Santa Cruz City Schools, Santa Cruz, California- Phase I ESA E95815.02 June 21, 2023 Page 20
Recognized Environmental Conditions
Based on Moore Twining’s review of historical documents for the Subject Property, the past uses of the Subject Property as a National Guard Armory/Military Police Depot with a garage and concrete ramp for vehicle/tank maintenance/repairs is a REC. A PEA conducted in 2002 identified several COCs with elevated concentrations in the vicinity of the former grease rack, but concentrations were deemed to be typical of those found in ‘urban environments’ and no further action was recommended; DTSC agreed and approved the PEA in July 2002.

Findings from this assessment and a concurrent geotechnical engineering subsurface investigation found groundwater to be at depths ranging from 3 to 6 feet below ground surface, and olfactory observations of petroleum hydrocarbon contamination in the central portion of the Subject Property. Additionally, a review of historical documents for the nearby Santa Cruz Industries facility, located at 411 Swift Street, indicate that monitoring well MW-18, which is located on the Subject Property, has historically had elevated concentrations of TCE above the CalEPA RSLs. Based on these findings, it is our opinion, further soil, groundwater and soil vapor assessment is warranted.

Controlled Recognized Environmental Condition
No CRECs were identified during the course of this assessment.

Historical Recognized Environmental Condition
No HRECs were identified during the course of this assessment.

Proposed Additional Investigations
Based on a review of historical documentation, the Subject Property and vicinity have continually been used for agricultural purposes. The legal application of agricultural chemicals is not considered a REC by the Comprehensive Environmental Response, Compensation and Liability (CERCLA) act of 1980. The exemption in noted in (4) Application of Pesticides – Section 107(i) of the ASTM 1527-21 standard. However, a clause is noted in the exemption stating, “The pesticide exemption also contains a ‘savings clause” that provides that the cost recovery prohibition does not alter or modify any obligations or liability under any other federal or state law for damages, injury or loss resulting from a release of hazardous substances, or for the costs of removal or remedial actions of such hazardous substances.” It has been Moore Twining’s experience that persistent pesticides can exist in soils after long-term use of agricultural chemicals. From the historical documents researched, no information was discovered that would indicate illegal agricultural activities occurred at the Subject Property. As the Subject Property was used from the 1930’s to 1940’s for agricultural purposes, the potential exists that persistent pesticides and other related agricultural chemicals may be present in the soils at the Subject Property. These constituents, even in low concentrations, can result in federal, state and local requirements for movement, disposal, assessment, and remediation. If present, costs could be incurred to address these conditions.

Re: PUBLIC RECORDS ACT REQUEST RECEIVED ON Monday, May 8, 2023 The City of Santa Cruz responds to your public records request for informa9on received on the above-referenced date, Monday, May 8, 2023 as indicated below.

Under the California Public Records Act (CPRA) you are en9tled to copies of iden9fiable, non-exempt public records (Govt. Code sec9on 7922.500). Please note that the CPRA requires the City to provide access to, or copies of, records responsive to your request which are in its possession, subject to certain excep9ons. The CPRA does not require the City to provide informa9on, answer ques9ons, or create records which do not exist.

A@er conduc9ng a reasonable search for requested records, the City Clerk, in consulta9on with Lee Butler, Director of Planning and Community Development, determined that certain responsive records or por9ons of responsive records are exempt from disclosure under the CPRA. Specifically, some records are redacted pursuant to the following exemp9on(s):
☒ Public Interest Exemp9on • Gov’t Code § 7922.000 • A@er careful considera9on, based on the facts of the par9cular case and/or the nature of the records requested, we have determined that the public interest in nondisclosure of personal informa9on such as [individual names, home addresses, telephone numbers, and email addresses] clearly outweighs the public interest served in disclosure of the record(s) in order to protect the privacy or iden9ty of individuals.

Except as stated above, the City has produced public records responsive to your California Public Records Act request.

These records are a
ached.

Subject: Former Santa Cruz Industries ‐ Second Work Plan Addendum for Off‐Site Vapor Intrusion Assessment
EXTERNAL:

Dean,
Attached are the following showing the results of the recent passive soil gas (PSG) and passive sewer gas sampling:
 Beacon Environmental’s laboratory data report that includes maps depicting concentrations of PCE, TCE, 11‐DCE, benzene, vinyl chloride, and total VOCs in soil vapor. The maps show both the results of the September 2022 PSG sampling and the November 28, 2022 results.  Tables summarizing the results of the passive soil gas and passive sewer gas analysis  A figure showing the results of the passive sewer gas sampling  A figure showing the proposed permanent soil vapor sampling probes (approximately 5 feet deep), sub‐slab vapor probes, and indoor/outdoor air sampling locations

22.1026
The results of the PSG study indicates that elevated concentrations of VOC are present over the sanitary sewer line beneath Delaware Avenue. Concentrations of chemicals of concern decrease to generally below commercial ESLs outside of the building at 2111 Delaware Avenue.

This email provides a proposed scope of work for the next phase of off‐site vapor intrusion assessment, and is intended to serve as an addendum to the July 28, 2022 Work Plan for Off‐Site Soil Vapor Intrusion Investigation, and the October 7, 2022 Work Plan Addendum for Off‐Site Vapor Intrusion Assessment (submitted by email). As shown on the fourth attachment, we propose installing permanent 5‐foot soil vapor probes to verify the results of the PSGs and to monitor VOC concentration over time at the following locations:
 Near PSG‐49 and PSG‐50 to monitor the concentrations of VOC, particularly vinyl chloride, in soil gas near those residences
 Near PSG‐58 to monitor VOCs in soil gas on the northeast side of the off‐site building at 2111 Delaware Avenue where there was a PCE exceedance to the commercial ESL  Near PSG‐55 and PSG‐57 to monitor VOCs on the north side of the off‐site building at 2111 Delaware Avenue
We propose installation of off‐site sub‐slab vapor probes at 5 locations within 2111 Delaware Avenue.

As presented in Trinity’s August 2, 2022 email (approved by the Water Board on August 3, 2022), sub‐ slab vapor samples will be analyzed for a full scan of VOCs and for radon. Indoor air samples that are co‐ located at each sub‐slab vapor probe will be analyzed for radon only. Additionally, outdoor air samples will be collected at four locations for radon only analysis. The results of radon analysis will be used to determine a site‐specific building slab attenuation factor and potential vapor intrusion risk using the methods described in Trinity’s April 23, 2021 Radon Study and Site‐Specific Cleanup Goals Report.

Please let us know if you approve of this approach.

Thanks.

The EDR Environmental Lien Search Report provides results from a search of available current land title records for environmental cleanup liens and other activity and use limitations, such as engineering controls and institutional controls.

A network of professional, trained researchers, following established procedures, uses client supplied address information to:
• search for parcel information and/or legal description; • search for ownership information;
• research official land title documents recorded at jurisdictional agencies such as recorders' offices, registries of deeds, county clerks' offices, etc.;
• access a copy of the deed;
• search for environmental encumbering instrument(s) associated with the deed; • provide a copy of any environmental encumbrance(s) based upon a review of key words in the instrument(s) (title, parties involved, and description); and • provide a copy of the deed or cite documents reviewed.

Thank you for your business.
