ADDENDUM NO. 1 QUESTIONS & ANSWERS

(As of April 18, 2017)

Q1: Sheet S1.101 shown the new Retaining Wall Footing Type A/S2.01 extending South past the corner of the Existing Single Story Cold Storage Building, see attached drawing. This will require shoring and undermining a portion of the existing building foundation in order to excavate and place the retaining wall footing. Please advise if this is the intended retaining wall footing configuration at this location.

A1: See attachment. For this location, the toe of the wall A/S2.01 may be reduced to avoid conflict with the existing building footing. The shortened toe width will be reduced from 6’-0” to 3’-4” at this location only, to avoid undermining the existing building footing.

Q2: Please review the following note from sheet G0.01. It was said at the job walk that the only item USCD wanted returned was the “Circuit Breaker Crane” mentioned in Note 7, all other pieces and parts to be demolished and removed from the site.

A2: In addition what is listed in the RFI (G0.01) contractor shall also provide the copper within the

existing SIO Substation back to UCSD. Q3: Is a soils report available per the following note? On sheet C1.00 it states: “1. All grading,

excavation, and embankment shall be in accordance with the geotechnical investigation, emergency testing, inc, Project No. 140510P3, dated November 17th.

A3: Please see the attached soil report for your reference. Q4: Specification 26 13 26, Part 1.7, F. Clarification - Vacuum Circuit Breakers with configured P/Ns

and insulated bussing are generally made-to-order, and not stock items with any Switchgear Manufacturer.

A4: Confirmed, the electrical equipment is made to order. Q5: Specification 26 13 26, Part 2.1, A. Clarification - This section specifically mention products by

one of the following: Square D, Eaton Cutler-Hammer, or Equal. Will UCSD allow other premium Switchgear OEM other than Square D or Eaton as Equal if this Switchgear OEM can provide the same features, functions, and characteristics, if not better than the other manufacturers specifically named?

A5: The alternate must be equal and documentation for said equal alternate shall be submitted to UCSD for review and approval within 30 days after the Notice to Proceed.

Q6: Specification 26 13 26, Part 2.2, A. Clarification - NEMA 4X is not an applicable rating for ANSI/IEEE C37.20.2 Switchgear construction. That said, equipment can/will be manufactured from either 304 or 316 (please advise) stainless steel, powder painted ANSI 61 grey. (See next item in this RFI.)

A6: 304 or 316 stainless steel are acceptable. Q7: Specification 26 13 26, Part 2.4, C. Question - Is preference for:

a) Outdoor Walk-in (i.e. common aisle, non-self-supporting, non-insulated) Switchgear construction; or b) PDC (i.e. self-supporting, insulated) construction containing Indoor Switchgear.


2 of 2

In case of "a," stainless steel Switchgear construction makes sense. In case of "b," we recommend the PDC exterior only be made of stainless or galvanized steel, with the Indoor Switchgear inside constructed of standard, cold-rolled steel powder painted ANSI 61 grey.

EXECUTIVE SUMMARY

This report presents the results of the geotechnical investigation Southern California Soil & Testing, Inc. (SCS&T) performed for the subject project. The site is located within Scripps Institution of Oceanography (SIO) in the La Jolla community of the City of San Diego, California. We understand the project will consist of the design and construction of 12-inch thick concrete slabs-on-grade for generator and switchgear pads, retaining walls, and piping. The purpose of our work is to provide conclusions and recommendations regarding the geotechnical aspects of the project.

SCS&T explored the subsurface conditions by drilling two borings using a limited-access drill rig equipped with a solid stem auger and excavating two test pits using hand tools. The borings were drilled to depths of about 5½ feet and 12½ feet below the existing ground surface. The test pits were excavated to depths of about 3 feet and 3½ feet below the existing ground surface. Each of the borings and test pits encountered refusal. An SCS&T geologist logged the borings and test pits and collected samples of the materials encountered for laboratory testing. SCS&T tested selected samples from the borings to evaluate pertinent soil classification and engineering properties to assist in developing geotechnical conclusions and recommendations.

The materials encountered in the explorations consist of fill, colluvium and Scripps Formation. The fill and colluvium consist of soft to medium stiff sandy lean clay with trace amounts of gravel. The Scripps Formation consists of hard sandy siltstone to sandy claystone. Groundwater was not encountered in the borings or test pits.

The main geotechnical considerations affecting the planned development are the presence of potentially compressible fill and colluvium and expansive soil. To reduce the potential for settlement, the existing fill and colluvium should be excavated in their entirety beneath settlement sensitive improvements. Additionally, Scripps Formation within 2 feet of finished pad grade should be excavated. To mitigate expansive soils, the concrete slabs-on-grade pads should be underlain by at least 2 feet of granular material with an expansion index of 50 or less. It is expected that most of the onsite soils will not meet the select granular material criteria. Strongly cemented zones should be expected in the Scripps Formation. Contract documents should specify that the contractor mobilize equipment capable of excavating and compacting materials with concretions to reduce the potential that claims for delays or extra work will arise. The recommendations presented herein may need to be updated once final plans are developed.

1 INTRODUCTION

This report presents the results of the geotechnical investigation Southern California Soil & Testing, Inc. (SCS&T) performed for the subject project. We understand the project will consist of the design and construction of 12-inch thick concrete slabs-on-grade for generator and switchgear pads, retaining walls, and piping. The purpose of our work is to provide conclusions and recommendations regarding the geotechnical aspects of the project. Figure 1 presents a site vicinity map.

2 SCOPE OF WORK

2.1 FIELD INVESTIGATION

SCS&T explored the subsurface conditions by drilling two borings using a limited-access drill rig equipped with a solid stem auger and excavating two test pits using hand tools. The borings were drilled to depths of about 5½ feet and 12½ feet below the existing ground surface. The test pits were excavated to depths of about 3 feet and 3½ feet below the existing ground surface. Each of the borings and test pits encountered refusal. Figure 2 shows the approximate locations of the borings and test pits. An SCS&T geologist logged the borings and test pits and collected samples of the materials encountered for laboratory testing. The logs of the borings and test pits are presented in Appendix I. Soils are classified according to the Unified Soil Classification System illustrated on Figure I-1.

2.2 LABORATORY TESTING

Selected samples obtained from the borings were tested to evaluate pertinent soil classification and engineering properties and enable development of geotechnical conclusions and recommendations. The laboratory tests consisted of:

• In Situ Moisture and Density • Grain Size Distribution • Atterberg Limits • R-Value • Expansion Index • Corrosivity • Direct Shear

The results of the laboratory tests, and brief explanations of test procedures, are presented in Appendix II.

2.3 ANALYSIS AND REPORT PREPARATION

The results of the field and laboratory tests were evaluated to develop conclusions and recommendations regarding:

• Subsurface conditions beneath the site • Potential geologic hazards • Criteria for seismic design in accordance with the 2013 California Building Code • Site preparation and grading

University of California, San Diego November 17, 2014 4746 SIO Emergency Power Improvements SCS&T No. 140510P3-1 La Jolla, California Page 2

• Appropriate alternatives for foundation support along with geotechnical engineering criteria for design of the foundations

• Support for concrete slabs-on-grade • Lateral pressures for the design of retaining walls • Pavement sections • Corrosion potential

2.4 ENVIRONMENTAL SOILS TESTING

SCS&T subcontracted with a State of California certified laboratory to perform environmental testing of the onsite soils as an indication of the presence of hazardous materials at the site. The analytical test results are presented in a separate report.

3 SITE AND SUBSURFACE CONDITIONS

3.1 SITE DESCRIPTION

The site is located within Scripps Institution of Oceanography (SIO) in the La Jolla community of the City of San Diego, California. The site is located south and west of Downwind Way at its intersection with Shellback Way and north of the existing Deep Sea Drilling East building. Existing improvements at the site consist of a refrigerated modular building and associated utilities and a parking lot paved with asphalt concrete. The northern and eastern portions of the site consist of slopes up to about 13 feet in height ascending up to Downwind Way at inclinations between about 2:1 and 1⅓:1 (horizontal:vertical). Slope vegetation consists of trees, bushes and weeds. Ground surface elevations range from about 180 feet at top of the slope at the southeast corner of the site to about 160 feet at the southwest corner of the site.

3.2 SUBSURFACE CONDITIONS

The materials encountered in the explorations consist of fill, colluvium and Scripps Formation. Descriptions of the materials are presented below. Figure 2 shows the site-specific geology. Figure 3 presents a geologic cross section. Figure 4 presents the regional geology in the vicinity of the site.

Fill - The fill consists of soft to medium stiff sandy lean clay with trace amounts of gravel. The fill extends to depths between about 2 feet and 3 feet below the existing ground surface.

Colluvium - Buried colluvium was encountered beneath the fill in boring B-1. The colluvium consists of soft to medium stiff sandy lean clay with trace amounts of gravel and extends to a depth of about 9½ feet below the existing ground surface.

Scripps Formation - The site is underlain by Scripps Formation. The Scripps Formation consists of hard sandy siltstone to sandy claystone.

Groundwater - Groundwater was not encountered in the borings or test pits. The permanent groundwater level is expected to be below a depth that will influence planned construction.


However, groundwater levels may fluctuate in the future due to rainfall, irrigation, broken pipes, or changes in site drainage. Because groundwater rise or seepage is difficult to predict, such conditions are typically mitigated if and when they occur.

4 GEOLOGIC HAZARDS

4.1 CITY OF SAN DIEGO SEISMIC SAFETY STUDY

Figure 5 shows the approximate site location on the City of San Diego Seismic Safety Study map. The site is located in Geologic Hazard Category 53, which is defined as level or sloping terrain with unfavorable geologic structure and low to moderate risk. In our opinion, the geologic risk is low.

4.2 CALIFORNIA BUILDING CODE SEISMIC DESIGN PARAMETERS

A geologic hazard likely to affect the project is groundshaking as a result of movement along an active fault zone in the vicinity of the subject site. The site coefficients and adjusted maximum considered earthquake spectral response accelerations in accordance with the 2013 California Building Code are presented below:

Site Coordinates: Latitude 32.86764° Longitude -117.25117° Site Class: C Site Coefficients, Fa = 1.000 Fv = 1.303 Mapped Spectral Response Acceleration at Short Periods, Ss = 1.281g Mapped Spectral Response Acceleration at 1-Second Period, S1 = 0.497g SDS = 0.854g SD1 = 0.432g PGAM = 0.578g

4.3 FAULTING AND SURFACE RUPTURE

The closest known active fault is the Rose Canyon fault zone (Del Mar section) located about 1½ kilometers west-southwest of the site. The nearest mapped fault is an unnamed fault located within 200 feet of the site (City of San Diego, 2008). This fault is not known to have offset Holocene sediments indicating it is not an active fault. The State of California does not consider this fault to be active, and an Alquist-Priolo Earthquake Fault Zone has not been established for the fault. It is our opinion that, according to State of California guidelines, the unnamed fault is not a potential source of seismic shaking or ground rupture. The site is not located in an Alquist-Priolo Earthquake Fault Zone. No active faults are known to underlie or project toward the site. Therefore, the probability of fault rupture is considered low.

4.4 LANDSLIDES AND SLOPE STABILITY

Evidence of landslides or slope instabilities was not observed. The potential for landslides or slope instabilities to occur at the site is considered low.


4.5 LIQUEFACTION AND DYNAMIC SETTLEMENT

Liquefaction occurs when loose, saturated, generally fine sands and silts are subjected to strong ground shaking. The soils lose shear strength and become liquid; potentially resulting in large total and differential ground surface settlements as well as possible lateral spreading during an earthquake. Due to the lack of shallow groundwater, and given the relatively dense nature of the materials beneath the site, the potential for liquefaction and dynamic settlement to occur is considered negligible.

4.6 FLOODING, TSUNAMIS AND SEICHES

The site is not located within a flood zone or dam inundation area. The site is not located within a mapped area on the State of California Tsunami Inundation Maps; therefore, damage due to flooding or tsunamis is considered negligible. Seiches are periodic oscillations in large bodies of water such as lakes, harbors, bays, or reservoirs. The site is not located adjacent to any lakes or confined bodies of water; therefore, the potential for a seiche to affect the site is negligible.

4.7 SUBSIDENCE

The site is not located in an area of known subsidence associated with fluid withdrawal (groundwater or petroleum); therefore, the potential for subsidence due to the extraction of fluids is negligible.

4.8 HYDRO-CONSOLIDATION

Hydro-consolidation can occur in recently deposited (less than 10,000 years old) sediments that were deposited in a semi-arid environment. Examples of such sediments are aolian sands, alluvial fan deposits, and mudflow sediments deposited during flash floods. The pore space between particle grains can re-adjust when inundated by groundwater causing the material to consolidate. The relatively dense materials beneath the site are not susceptible to hydro-consolidation.

5 CONCLUSIONS

The main geotechnical considerations affecting the planned development are the presence of potentially compressible fill and colluvium and expansive soil. Site preparation will need to be performed in areas to receive on-grade slabs, retaining walls or new fill to reduce the potential for distress to the planned improvements. Strongly cemented zones should be expected in the Scripps Formation. Contract documents should specify that the contractor mobilize equipment capable of excavating and compacting materials with concretions to reduce the potential that claims for delays or extra work will arise.


6 RECOMMENDATIONS

6.1 SITE PREPARATION AND GRADING

6.1.1 Site Preparation

Site preparation should begin with the removal of existing improvements, vegetation and debris. The existing fill and colluvium should be excavated in their entirety in areas to receive slabs-on-grade, retaining walls or new fill. Additionally, Scripps Formation within 2 feet of finished pad grade should be excavated. Horizontally, the excavation should extend at least 2 feet outside the perimeter of the improvements or up to existing improvements, whichever is less. The concrete slabs-on-grade should be underlain by at least 2 feet of granular material with an expansion index of 50 or less determined in accordance with ASTM D4829. We anticipate that most of the onsite soils will not meet the select granular material criteria. A SCS&T representative should observe conditions exposed in the bottom of the excavation to determine if additional excavation is required.

6.1.2 Earthwork

Fill should be placed in 6- to 8-inch thick loose lifts, moisture conditioned to near optimum moisture content, and compacted to at least 90% relative compaction. Where fill is to be placed on surfaces inclined steeper than 5:1 (horizontal:vertical), benches should be excavated to provide a relatively level surface for fill placement. The maximum dry density and optimum moisture content for the evaluation of relative compaction should be determined in accordance with ASTM D1557. Utility trench backfill beneath structures and on-grade slabs should be compacted to at least 90% relative compaction.

6.1.3 Imported Soil

Imported soil should consist of predominately granular soil free of organic matter and rocks greater than 6 inches. Imported soil should have an expansion index of 20 or less and should be inspected and, if appropriate, tested by SCS&T prior to transport to the site.

6.1.4 Expansive Soil

The onsite soils tested have a medium expansion potential. The recommendations presented in this report reflect a low expansion potential.

6.1.5 Site Excavation Characteristics

It is anticipated that excavations can be achieved with conventional earthwork equipment in good working order. Difficult excavation in strongly cemented materials should be anticipated within the Scripps Formation. Contract documents should specify that the contractor mobilize equipment capable of excavating and compacting materials with concretions to reduce the potential that claims for delays or extra work will arise.


6.1.6 Oversized Material

Excavations may generate oversized material. Oversized material is defined as rocks or cemented clasts greater than 6 inches in largest dimension. Based on the planned construction, there does not appear to be suitable space onsite for disposal of oversized material within fills. Oversized material should be broken down to no greater than 6 inches in largest dimension for use in fill, used as landscape material, or disposed offsite.

6.1.7 Temporary Excavation Slopes

Temporary excavations 3 feet deep or less can be made vertically. Deeper temporary excavations in fill or colluvium should be laid back no steeper than 1:1 (horizontal:vertical). Deeper temporary excavations in Scripps Formation should be laid back no steeper than ¾:1 (horizontal:vertical). The faces of temporary slopes should be inspected daily by the contractor’s Competent Person before personnel are allowed to enter the excavation. Any zones of potential instability, sloughing or raveling should be brought to the attention of the Engineer and corrective action implemented before personnel begin working in the excavation. Excavated soils should not be stockpiled behind temporary excavations within a distance equal to the depth of the excavation. SCS&T should be notified if other surcharge loads are anticipated so that lateral load criteria can be developed for the specific situation. If temporary slopes are to be maintained during the rainy season, berms are recommended along the tops of slopes to prevent runoff water from entering the excavation and eroding the slope faces. Slopes steeper than those described above or temporary excavations that extend below a plane inclined at 1½:1 (horizontal:vertical) downward from the outside bottom edge of existing structures or improvements will require shoring. A shoring system consisting of soldier piles and lagging can be used.

6.1.8 Temporary Shoring

For design of cantilevered shoring, an active soil pressure equal to a fluid weighing 35 pcf can be used for level retained ground or 55 pcf for 2:1 (horizontal:vertical) sloping ground. The surcharge loads on shoring from traffic and construction equipment adjacent to the excavation can be modeled by assuming an additional 2 feet of soil behind the shoring. An allowable passive pressure of 350 psf per foot of embedment (over twice the pile diameter) up to a maximum of 7,500 psf can be used for soldier piles embedded in formation. Soldier piles should be spaced at least three pile diameters, center to center.

6.1.9 Slopes

All permanent slopes should be constructed at an inclination of 2:1 (horizontal:vertical) or flatter. Faces of fill slopes should be compacted either by rolling with a sheep-foot roller or other suitable equipment, or by overfilling and cutting back to design grade. All slopes are


susceptible to surficial slope failure and erosion. Water should not be allowed to flow over the top of slopes. Additionally, slopes should be planted with vegetation that will reduce the potential for erosion.

6.1.10 Surface Drainage

Final surface grades around structures should be designed to collect and direct surface water away from structures and toward appropriate drainage facilities. The ground around the structure should be graded so that surface water flows rapidly away from the structure without ponding. In general, we recommend that the ground adjacent to the structure slope away at a gradient of at least 2%. Densely vegetated areas where runoff can be impaired should have a minimum gradient of at least 5% within the first 5 feet from the structure. Roof gutters with downspouts that discharge directly into a closed drainage system are recommended on structures. Drainage patterns established at the time of fine grading should be maintained throughout the life of the proposed structures. Site irrigation should be limited to the minimum necessary to sustain landscape growth. Should excessive irrigation, impaired drainage, or unusually high rainfall occur, saturated zones of perched groundwater can develop.

6.1.11 Grading Plan Review

SCS&T should review the grading plans and earthwork specifications to ascertain whether the intent of the recommendations contained in this report have been implemented, and that no revised recommendations are needed due to changes in the development scheme.

6.2 FOUNDATIONS

6.2.1 Shallow Spread Footings

Shallow spread footings with bottom levels on compacted fill or Scripps Formation can be used to support the planned retaining walls. Footings should extend at least 24 inches below lowest adjacent finished grade. A minimum width of 18 inches is recommended. An allowable bearing capacity of 2,500 pounds per square foot (psf) can be used. Lateral loads will be resisted by friction between the bottoms of footings and passive pressure on the faces of footings and other structural elements below grade. An allowable coefficient of friction of 0.30 can be used. Passive pressure can be computed using an allowable lateral pressure of 350 psf per foot of depth below the ground surface. The upper 1 foot of soil should not be relied on for passive support unless the ground is covered with pavements or slabs. The bearing and passive pressure values can be increased by ⅓ when considering the total of all loads, including wind or seismic forces. Footings located adjacent to or within slopes should be extended to a depth such that a minimum horizontal distance of 7 feet exists between the lower outside footing edge and the face of the slope.


6.2.2 Settlement

Total foundation settlements are estimated to be less than 1 inch. Differential settlements across continuous footings are estimated to be less than ¾ inch over a distance of 40 feet. Settlements should be completed shortly after structural loads are applied.

6.2.3 Foundation Plan Review

SCS&T should review the foundation plans to ascertain that the intent of the recommendations in this report has been implemented and that revised recommendations are not necessary as a result of changes after this report was completed.

6.2.4 Foundation Excavation Observations

A representative from SCS&T should observe the foundation excavations prior to forming or placing reinforcing steel.

6.3 SLABS-ON-GRADE

The top 2 feet of material below the planned concrete slabs-on-grade should have an expansion index of 50 or less determined in accordance with ASTM D4829. Slabs should be provided with weakened plane joints. Joints should be placed in accordance with the American Concrete Institute guidelines. The project architect should select the final joint patterns. A 1-inch maximum size aggregate mix is recommended for concrete. The corrosion potential of on-site soils with respect to reinforced concrete will need to be taken into account in concrete mix design. Coarse and fine aggregate in concrete should conform to the “Greenbook” Standard Specifications for Public Works Construction.

6.4 CONVENTIONAL RETAINING WALLS

6.4.1 Foundations

Foundation recommendations were provided in Section 6.2.1 of this report.

6.4.2 Lateral Earth Pressures

The active earth pressure for the design of unrestrained earth retaining structures with level backfills can be taken as equivalent to the pressure of a fluid weighing 40 pcf. The at-rest earth pressure for the design of restrained earth retaining structures with level backfills can be taken as equivalent to the pressure of a fluid weighing 60 pcf. The above values assume a granular and drained backfill condition. Higher lateral earth pressures would apply if walls retain expansive clay soils. An additional 20 pcf should be added to these values for walls with a 2:1 (horizontal: vertical) sloping backfill. An increase in earth pressure equivalent to an additional 2 feet of retained soil can be used to account for surcharge loads from light traffic. The above values do not include a factor of safety. Appropriate factors of safety should be incorporated into the design. If any other


surcharge loads are anticipated, SCS&T should be contacted for the necessary increase in soil pressure.

Retaining walls should be designed to resist hydrostatic pressures or be provided with a backdrain to reduce the accumulation of hydrostatic pressures. Backdrains may consist of a 2-foot wide zone of ¾-inch crushed rock. The backdrain should be separated from the adjacent soils using a non-woven filter fabric, such as Mirafi 140N or equivalent. Weep holes should be provided or a perforated pipe (Schedule 40 PVC) should be installed at the base of the backdrain and sloped to discharge to a suitable storm drain facility. As an alternative, a geocomposite drainage system such as Miradrain 6000 or equivalent placed behind the wall and connected to a suitable storm drain facility can be used. The project architect should provide waterproofing specifications and details. Figure 6 shows typical conventional retaining wall backdrain details.

6.4.3 Seismic Earth Pressure

If required, the seismic earth pressures can be taken as equivalent to the pressure of a fluid weighing 22 pounds per cubic foot (pcf) for flexible walls and 43 pcf for stiff walls. These values are for level backfill conditions and do not include a factor of safety. Appropriate factors of safety should be incorporated into the design. This pressure is in addition to the un-factored static active pressures. The allowable passive pressure and bearing capacity can be increased by ⅓ in determining the stability of the wall.

6.4.4 Backfill

All backfill soils should be compacted to at least 90% relative compaction. Backfill soils should consist of granular, free-draining material having an expansion index of 20 or less determined in accordance with ASTM D4829. Expansive or clayey soil should not be used for backfill material. We anticipate that most of the onsite soils will not meet the granular material criteria. Additionally, fill within 3 feet from the back of the wall should not contain rocks greater than 3 inches in any dimension. The wall should not be backfilled until the grout has reached an adequate strength.

6.5 PAVEMENT SECTION RECOMMENDATIONS

The pavement support characteristics of the soils encountered during our investigation are considered poor to moderate. An R-value of 17 was assumed for design of preliminary pavement sections. The actual R-value of the subgrade soils should be determined after grading and final pavement sections be provided. Based on an R-value of 17, the following pavement structural sections are recommended for the assumed Traffic Indices.


Flexible Pavement Sections

Traffic Type Traffic Index Asphalt Concrete

(inches) Aggregate Base*

(inches)

Parking Stalls 4.5 3 7

Drive Lanes 6.0 4 9

Heavy Traffic Areas 7.0 5 11 *Aggregate Base should conform to Class 2 Aggregate Base in accordance with the Caltrans Standard Specifications or Crushed Miscellaneous Base in accordance with the Standard Specifications for Public Works Construction.

Heavy Traffic Areas 7.0 7 6 *Jointed Plain Concrete Pavement

The top 12 inches of subgrade should be scarified, moisture conditioned to near optimum moisture content, and compacted to at least 95% relative compaction. All soft or yielding areas should be removed and replaced with compacted fill. If the subgrade consists of competent Scripps Formation, scarification and recompaction need not be performed. The aggregate base material should be compacted to at least 95% relative compaction. All materials and methods of construction should conform to good engineering practices and the minimum standards of UCSD.

6.6 SOIL CORROSIVITY

A representative sample of the onsite soils was tested to evaluate corrosion potential. The test results are presented in Appendix II. The project design engineer can use the sulfate results in conjunction with ACI 318 to specify the water/cement ratio, compressive strength and cementitious material types for concrete exposed to soil. A corrosion engineer should be contacted to provide specific corrosion control recommendations.

7 GEOTECHNICAL ENGINEERING DURING CONSTRUCTION

The geotechnical engineer should review project plans and specifications prior to bidding and construction to check that the intent of the recommendations in this report has been incorporated. Observations and tests should be performed during construction. If the conditions encountered during construction differ from those anticipated based on the subsurface exploration program, the presence of the geotechnical engineer during construction will enable an evaluation of the


exposed conditions and modifications of the recommendations in this report or development of additional recommendations in a timely manner.

8 CLOSURE

SCS&T should be advised of any changes in the project scope so that the recommendations contained in this report can be evaluated with respect to the revised plans. Changes in recommendations will be verified in writing. The findings in this report are valid as of the date of this report. Changes in the condition of the site can, however, occur with the passage of time, whether they are due to natural processes or work on this or adjacent areas. In addition, changes in the standards of practice and government regulations can occur. Thus, the findings in this report may be invalidated wholly or in part by changes beyond our control. This report should not be relied upon after a period of two years without a review by us verifying the suitability of the conclusions and recommendations to site conditions at that time.

In the performance of our professional services, we comply with that level of care and skill ordinarily exercised by members of our profession currently practicing under similar conditions and in the same locality. The client recognizes that subsurface conditions may vary from those encountered at the boring locations, and that our data, interpretations, and recommendations are based solely on the information obtained by us. We will be responsible for those data, interpretations, and recommendations, but shall not be responsible for interpretations by others of the information developed. Our services consist of professional consultation and observation only, and no warranty of any kind whatsoever, express or implied, is made or intended in connection with the work performed or to be performed by us, or by our proposal for consulting or other services, or by our furnishing of oral or written reports or findings.

APPENDIX I

APPENDIX I FIELD INVESTIGATION

Our field investigation consisted of drilling two borings using a limited-access drill rig equipped with a solid stem auger and excavating two test pits using hand tools on October 24, 2014. The borings were drilled to depths of about 5½ feet and 12½ feet below the existing ground surface. The test pits were excavated to depths of about 3 feet and 3½ feet below the existing ground surface. Each of the borings and test pits encountered refusal. Figure 2 shows the approximate locations of the borings and test pits. The field investigation was performed under the observation of an SCS&T geologist who also logged the borings and test pits and obtained samples of the materials encountered.

Relatively undisturbed samples were obtained using a modified California (CAL) sampler, which is ring-lined split tube sampler with a 3-inch outer diameter and 2½-inch inner diameter. Standard Penetration Tests (SPT) were performed using a 2-inch outer diameter and 1⅜-inch inner diameter split tube sampler. The CAL and SPT samplers were driven with a 140-pound weight dropping 30 inches. The number of blows needed to drive the samplers the final 12 inches of an 18-inch drive is noted on the borings logs as “Driving Resistance (blows/foot of drive).” SPT and CAL sampler refusal was encountered when 50 blows were applied during any one of the three 6-inch intervals, a total of 100 blows was applied, or there was no discernible sampler advancement during the application of 10 successive blows. Disturbed bulk samples were obtained from the SPT sampler and drill cuttings.

The soils are classified in accordance with the Unified Soil Classification System as illustrated on Figure I-1. Logs of the borings and test pits are presented on Figures I-2 through I-6.

Dear Rosalie:

In accordance with your authorization, Southern California Soil & Testing, Inc. (SCS&T) collected

environmental soil samples from the two borings and two test pits excavated on October 24, 2014

for the subject project. Figure 1 shows the approximate locations of the borings and test pits. The

soil samples were placed in 4-ounce jars, labeled, stored in an insulated cooler with ice, and

transported under chain-of-custody to Eurofins | Calscience for analytical testing. The sampling

equipment was decontaminated between samples to reduce the likelihood of cross-contamination.

The environmental test results are presented in the attached analytical report.

We appreciate this opportunity to provide professional services. If you have any questions

Qualifiers Definition

* See applicable analysis comment.

< Less than the indicated value.

> Greater than the indicated value.

1 Surrogate compound recovery was out of control due to a required sample dilution. Therefore, the sample data was reported without furtherclarification.

2 Surrogate compound recovery was out of control due to matrix interference. The associated method blank surrogate spike compound wasin control and, therefore, the sample data was reported without further clarification.

3 Recovery of the Matrix Spike (MS) or Matrix Spike Duplicate (MSD) compound was out of control due to suspected matrix interference. Theassociated LCS recovery was in control.

4 The MS/MSD RPD was out of control due to suspected matrix interference.

5 The PDS/PDSD or PES/PESD associated with this batch of samples was out of control due to suspected matrix interference.

6 Surrogate recovery below the acceptance limit.

7 Surrogate recovery above the acceptance limit.

B Analyte was present in the associated method blank.

BU Sample analyzed after holding time expired.

BV Sample received after holding time expired.

E Concentration exceeds the calibration range.

ET Sample was extracted past end of recommended max. holding time.

HD The chromatographic pattern was inconsistent with the profile of the reference fuel standard.

HDH The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified standard but heavier hydrocarbonswere also present (or detected).

HDL The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified standard but lighter hydrocarbons werealso present (or detected).

J Analyte was detected at a concentration below the reporting limit and above the laboratory method detection limit. Reported value isestimated.

JA Analyte positively identified but quantitation is an estimate.

ME LCS Recovery Percentage is within Marginal Exceedance (ME) Control Limit range (+/- 4 SD from the mean).

ND Parameter not detected at the indicated reporting limit.

Q Spike recovery and RPD control limits do not apply resulting from the parameter concentration in the sample exceeding the spikeconcentration by a factor of four or greater.

SG The sample extract was subjected to Silica Gel treatment prior to analysis.

X % Recovery and/or RPD out-of-range.

Z Analyte presence was not confirmed by second column or GC/MS analysis.

Solid - Unless otherwise indicated, solid sample data is reported on a wet weight basis, not corrected for % moisture. All QC results arereported on a wet weight basis.

Any parameter identified in 40CFR Part 136.3 Table II that is designated as "analyze immediately" with a holding time of <= 15 minutes(40CFR-136.3 Table II, footnote 4), is considered a "field" test and the reported results will be qualified as being received outside of thestated holding time unless received at the laboratory within 15 minutes of the collection time.

A calculated total result (Example: Total Pesticides) is the summation of each component concentration and/or, if "J" flags are reported,estimated concentration. Component concentrations showing not detected (ND) are summed into the calculated total result as zeroconcentrations.
