Subject: Approval of Plans, Specifications and Contract Documents and Authorization to Advertise for Bids for the Valley Street Water Main Replacement Project and the Foxtail Loop, Palomar Oaks Way and Tyler Street Alley Sewer Projects
Districts: 1 and 2
Recommended Actions
1. Adopt a Carlsbad Municipal Water District Board of Directors resolution approving plans, specifications and contract documents and authorizing the Secretary of the Board of Directors to advertise for bids for the Valley Street Water Main Replacement Project.
2. Adopt a City Council resolution approving the plans, specifications, and contract documents and authorizing the City Clerk to advertise for bids for the Foxtail Loop, Palomar Oaks Way and Tyler Street Alley Sewer projects.
Executive Summary
The Carlsbad Municipal Water District and the City of Carlsbad replace water and sewer pipelines as needed to maintain reliable service. This project will replace 545 feet of water pipelines in the Carlsbad Municipal Water District and 1,300 feet of sewer pipelines in the city’s service area at four locations. The pipelines selected for replacement were chosen because of their age, condition and size, and to prevent sewer overflows in three locations.
The water and sewer pipeline replacements are bundled into one project for economy of scale, common pipeline construction methods and to increase the potential number of interested bidders.
The project will be funded through the city’s Miscellaneous Pipeline Replacement Program (Capital Improvement Program Project No. 3904) and Sewer Line Rehabilitation and Replacement Program (CIP Project No. 5503), so no additional funding is required or being requested.
The construction cost estimate for the project is $1,832,000. CMWD Board and City Council approvals of the plans, specifications and contract documents are required before the city can Jan. 9, 2024
Item #6 Page 1 of 14
advertise for construction bids under Carlsbad Municipal Code Section 3.28.080(E), which requires construction projects to be formally bid when the value exceeds limits established by the California Uniform Construction Cost Accounting Commission. The limit is currently $200,000.
Explanation & An alysis
This project will construct a total of 1,845 feet of sewer and water pipelines to replace aging utility infrastructure at four noncontiguous locations within the service areas of the CMWD, which provides potable water to its customers, and the city, which provides sewage services.
The work consists of a water main replacement on Valley Street and sewer main replacements at Foxtail Loop, Palomar Oaks Way and the Tyler Street Alley. The four projects are being bundled into one bid package due to the commonality in pipeline construction methods for each site. Staff expect the city will receive more favorable bids and bidder interest with the projects bundled together than if each portion were bid separately.
Site 1
The Valley Street Water Main Replacement project will replace 545 linear feet of existing 8- inch diameter asbestos cement pipe water main between Magnolia and Andrea Avenues with new 8-inch diameter polyvinyl chloride, or PVC, pipe. The pipe segment was originally constructed in 1962 and provides potable water and fire services to Valley Middle School and an irrigation service to Magnolia Elementary School. The timing of the improvements has been coordinated with planned work at the Carlsbad Unified School District campuses and future street and drainage improvements by the Transportation Department.
Construction will occur during the CUSD 2024 summer break to avoid traffic impacts during the school year. The water main replacement will also be coordinated with any Transportation Department construction.
Site 2
The Foxtail Loop Sewer Replacement project (referred to as the “South Agua Hedionda Interceptor”, or SAHI Reach T1D Improvement project in the plans, specifications and contract documents) involves a segment of a major sewer line that was originally constructed in 2000 as part of the Terraces at Sunny Creek development. The 8-inch diameter sewer line is under the size called for by city engineering standards at three locations within the neighborhood. Residents who live near these segments have notified staff of strong sewage odors, which are often the result of undersized sewer lines. Staff have verified the need to increase the pipeline size at these locations to permit the passage of gases within the system and resolve the odor issues.
This portion of the project will remove 562 feet of an 8-inch diameter sewer line and replace it with 362 feet of a 12-inch diameter sewer line and 200 feet of a 15-inch diameter sewer line. An additional 50 feet of an 8-inch diameter sewer line will also be constructed to create system redundancy within the neighborhood.
This part of the project meets the criteria for funding from the city’s funding program, which collects fees for the construction of sewer improvements identified as needed that are not funded by the city’s sewer connection fee program. (The Sewer Benefit Area funding program will reimburse the Sewer Replacement Fund once all construction cost and services have been finalized.)

Item #6 Page 2 of 14
Site 3
The Palomar Oaks Way Sewer Extension project will abandon 70 feet of an existing 8-inch diameter sewer line, remove 50 feet of existing 8-inch diameter sewer line and reroute flows with 500 feet of an 8-inch diameter pipe. The sewer extension and rerouting will allow disconnection of the collector sewer from the adjacent Buena Interceptor Sewer to decrease the likelihood of a sewer system overflow caused by high flow in the Buena Interceptor Sewer.
Site 4
The Tyler Street Alley Sewer Replacement project will replace 280 feet of 8-inch sewer line constructed in 1930. The site is located in the Tyler Street alleyway north of Grand Avenue and between State and Roosevelt Streets. Recent inspections reveal structural distress. This site will be constructed last in the sequence of work in this project to minimize construction impacts to adjacent businesses during the peak summer tourist season and other scheduled events in the Village.
Fiscal An alysis
The engineer’s construction estimate for the project is $1,832,000. The total project cost of $2,691,000 includes estimated construction costs, contingency, engineering support, public outreach, and construction management and inspection services.
The Water Replacement Fund will provide funding for the water main replacement at Valley Street while the Sewer Replacement Fund will be used to fund the remaining three sites. A summary of the estimated costs and available funds for each funding source are shown in the tables below:

Item #6 Page 3 of 14
* Foxtail Loop will be itemized separately for reimbursement by the SBA Area E Fund.
Costs for the Foxtail Loop Sewer Improvements will be tracked separately during construction.
Upon completing the project, staff will return to the City Council for its authorization for the Sewer Benefit Area E Fund to reimburse the Sewer Replacement Fund for its contribution for the construction costs of the Foxtail Loop Sewer Replacement project.
Next Steps
With the CMWD Board and the City Council’s approvals, the Secretary of the Board of Directors and City Clerk will advertise a request for bids for the Project. Staff will then evaluate the bids received and identify the lowest responsive and responsible bidder. Staff will then return to the CMWD Board and the City Council with a recommendation to award a construction contract to the identified lowest responsible and responsive bidder.
Environmental Evaluation
The project is classified as a replacement or reconstruction of existing utility and/or facilities involving negligible, or no expansion of capacity and the City Planner has determined it is exempt from environmental review according to California Environmental Quality Act Guidelines Sections 15302(c) and 15303(d). If the resolutions are approved, staff will file a notice of exemption with the San Diego County Clerk in compliance with Section 21152(b) of the California Public Resources Code.

Except as s pecified in these P rovisions, the Ag ency will bear the cost o f testing of locall y produced materials and/or on-site workmanship where the results of such tests meet or exceed the req uirements ind icated in the Stan dard Specificati ons, Technical Spe cification, and any Supplemental Provisions. The cost of all other tests shall be borne by the Contractor.
At the option of the Engineer, the source of supply of each of the materials shall be approved by the Engineer before the delivery is started. All materials proposed for use ma y be inspected or tested at any time during their preparation and use. If, after incorporating such materials into the Work, it is found that sourc es of supply tha t have been a pproved do n ot fur nish a uniform product, or if the product from any source proves unacceptable at any time, the Contractor shall
Revised 6/15/17 Contract Nos. 3904 and 5503 Page 81 of 159 furnish app roved material from other approved source s. I f any product pr oves unacceptable after improper storage, handling or for any other reason it shall be r ejected, not i ncorporated into the work and shall be removed from the project site all at the Contractor’s expense.
Compaction tests may be made by the Engineer and all costs for tests that meet or exceed the requirements of the specifications shall be borne by the Agency. Said tests may be made at any place along the work as deemed necessary by the Engineer. The costs of any retests made necessary by noncompliance with the specifications shall be borne by the Contractor.
4-1.5 Certification. The Engine er may waive mat erials testing requirements of the Specifications and accept the manufacturer’s wri tten certi fication that the materials to be supplied meet those requirements. Material test data may be required as part of the certification.
4-1.6 Trade Names or Equals. The Contractor may supply any of the materials specified or offer an equivalent. The Engineer shall determine whether the material o ffered is equivalent to that specified. Adequate time shall be allowed for the Engineer to make this determination.
Whenever any particular material, pro cess, or equipment is indicated by patent, proprietary or brand name, or by name of manufacturer, such wording is used for the purpose of facilitating its description and shall be deemed to be followed by the words “or equal”. A listing of materials is not intended t o be com prehensive, or in order of prefere nce. The C ontractor may offer any material, proce ss, or equipment cons idered to be equivalent to th at indicated .
The substantiation of offers shall be submitted as provided in the Contract Documents.
The Contractor shall, at its expense, furnish data concerning items offered by it as equivalent to those specified. The Contr actor shall have the mat erial tested as r equired by the Engineer to determine that the quality, strengt h, p hysical, chem ical, or othe r cha racteristics, including durability, finish, efficiency, dimensions, service, and suitability are such that the item wi ll fulfill its intended function.
Test methods shall be subject to the approval of the Engineer. Test results shall be reported promptly to the Engineer, who will evaluate the results and determine if th e substitute item is equivalent. The Engineer’s findings shall be final. Installation and use of a substitute item shall not be made until approved by the Engineer.
If a s ubstitute offered by the Contractor is not found to be equal to th e specified material, the Contractor shall furnish and install the specified material.
The specified Contract completion time shall not be affected by any c ircumstance developing from the provisions of this section.
The Contractor is responsible for the satisfactory performance of substituted items. If, in the sole opinion of th e En gineer, the su bstitution is det ermined to be unsatisfactory in performance, appearance, durab ility, compatibil ity with asso ciated items, avail ability of repa ir parts and suitability of application the Contractor shall remove the substituted item and replace it with the originally specified item at no cost to the Agency.
4-1.7 Weighing and Meterin g Eq uipment. All scales and me tering equipment us ed for proportioning materials shall be insp ected for accuracy and certified within the past 12 months by the State of California Bureau of Weights and Measures, by the County Director or Sealer of Weights and Measures, or by a scale mechanic registered with or licensed by the County.

Calibration certificates shall be provided when requested by the Engineer.
4-1.9 Construction Materials Dis pute Resolution (Soils, Rock Mate rials, Concre te, Mortar and Related Materials, Masonry Materials, Bituminous Materials, Rock Products, and Modified Asphalts). In the interest of safety and public value, whenever credible evidence arises to c ontradict the test values of materials, the Agency and the C ontractor will initiate an immediate and cooperative investigation. Test values of materials are resul ts of the materials’ tests, as defined by the se Sp ecifications or by the spe cial pr ovisions, r equired to acc ept the Work. C redible evidence i s process obs ervations o r test v alues gathered using industry accepted practices. A contradiction exists whenever t est values or process observations of the same or similar materials are diverse enough such that the work ac ceptance or per formance becomes suspect. The i nvestigation shall allow access to all test results, procedures, and facilities relevant to the disput ed work and consider all av ailable information and , when necessary, g ather new and additional information in an attempt to determine the vali dity, the cause, a nd if necessary, the remedy t o the contradiction. If the c ooperative investigation reaches any re solution mechanism ac ceptable t o b oth the Age ncy a nd the Contr actor, the contradiction s hall b e considered r esolved and the cooperative investigation conc luded.
Whenever the cooperative investigation is unable to reach resolution, the investigation may then either conclude wit hout resolution or conti nue by written notification of one party to the other requesting the implement ation of a resolut ion process b y com mittee. The co ntinuance of th e investigation shall be contingent upon recipient’s agreement and acknowledged in writing within 3 calendar days after receiving a request. Wit hout ac knowledgement, the invest igation shall conclude without resolution. The committee shall consist of three State of California Registered Civil Engineers. Within 7 calendar days after the written request notification, the Agency and the Contractor wil l each select one engineer. With in 14 calendar days of the writte n request notification, the two selected engineers will select a third engineer. The goal in selection of the third member is to complem ent the professional experience of the fi rst two engineers. Should the two engineers fa il to select th e third engineer, the Agency an d the Contractor shall each propose 2 engineers to be the third member within 21 calendar days after t he written request notification. T he first tw o eng ineers previ ously s elected shall then select one of the fo ur proposed engineers in a blind draw. The com mittee shall be a c ontinuance of t he cooperative investigation and will re -consider all available info rmation and if necessary, gather n ew and additional information to determine the validity, the cause, and if necessary, the remedy to the contradiction. The committee will focus upon the performance adequacy of the material(s) using
Revised 6/15/17 Contract Nos. 3904 and 5503 Page 83 of 159 standard engineering pr inciples and practice s and to ensure public v alue, the committee may provide engineering recommendations as necessary. Unless otherwise agreed, the commit tee will have 30 calendar days from its formation to complete their review and submit their findings.
The final resolution of the committee shall b e by majority opi nion, i n writi ng, sta mped and signed. Should t he final resolu tion not be unanimous, the diss enter may a ttach a written, stamped, and signed minority opinion. Once started, the resolution process by committee shall continue to full conclusion unless:
1. Within 7 days of the formation of the committee, the Agency and the Contractor reach an acceptable resolution mechanism; or
2. Within 14 days of the formation of the committee, the initiating party withdraws its written notification and agrees to bear all investigative related costs thus far incurred; or
3. At any point by the mutual agreement of the Agency and the C ontractor. Unless otherwise agreed, the Con tractor sh all bear and maintain a reco rd for all the investigative costs until resolution. Should t he investigation discover assignable causes for the contradiction, the assignable party, th e Agency or the Contrac tor, shall bear all costs associated with t he investigation. Should assignable ca uses for the contradi ction extended to both parties, the investigation will assign costs cooperatively with each party or when necessary, equally. Should the investigation substantiate a contradiction without assignable cause, t he inves tigation will assign costs cooperatively with each pa rty or when necessary, equal ly. Should th e i nvestigation be unable to su bstantiate a contradiction, the initiator of th e investigation shall bear all investigative costs. All claim notification r equirements of the contract pertaining to the con tradiction s hall be suspended until the investigation is concluded.
4-2 MATERIALS TRANSPORTATION, HANDLING AND STORAGE. The Contractor shall order, purchase, transport, coordinate delivery, accept delivery, confirm the quantity and quality received, prepare storage a rea(s), store, handle, protect, move, relocate, remove and dispose excess of all materials used to accompl ish the Work.

6-1.1 Pre-Construction Meeting. After, or up on, notification of contract award, the Engi neer will set the time and location for the Preconstruction Meeting. Attendance of the Contractor’s management personnel responsible for the management, administration, and execution of th e project is mandatory f or t he me eting to be conv ened. Failure of the Contractor t o have the Contractor’s responsible project personnel attend the Preconstruction Meeting will be grounds for default by Contractor per Section 6-4. No separate payment will be made for the Contractor’s attendance at the meeting. The notice to proceed will only be issued on or after the completion of the preconstruction meeting.
6-1.1.1 Baseline Construc tion S chedule. The Contr actor shall prepare t he Baseli ne Construction Schedule as a Critical Path Method (CPM) Schedule in the precedence d iagram method (ac tivity-on-node) f ormat and submit the schedule in accord ance with 2 -5.3. The schedule shall:
A. Be pre pared u sing a commercially available, Windows compatible software program, “Suretrak” by Primavera or “Project” by Microsoft Corporation or approved equal.
B. Be prepared in hard copy ( paper) and electronic (Adobe PDF) format and free of file locking, encryption or any other protocol that would impede full access to the data and labeled wi th the project n ame and number, the Contractor’s name and th e date of preparation.
C. Begin with the d ate projected for the Notice to Proceed and conclude with the date of final completion conforming with the Contract time.
D. Depict a time-scaled n etwork diagram of all ac tivities, l ogic r elationships of interdependent activities, and milestones comprising the complete period of Work with tasks on the vertical axis and their d urations o n the horizontal ax is. Use distinctive texture patterns or line types to show the critical path within the Contract time. Include a tabular listing of each activity and its identification number, description, duration, early start, early finish, late st art, late finish, tota l float , and all p redecessor and successor activities. The numb er of a ctivities w ill co mmunicate the Contractor’s pl an fo r project execution, accurately describe the project work and allow monitoring and evaluation of progress and time impacts. Activity descriptions shall accurately define the work planned for the activity. Activity durations shall not be shorter than 1 working day or longer than 15 working days unless approved by the Engineer.
E. Include detail of all pro ject phasin g, st aging and sequencing including all miles tones necessary to define beginning and ending of each phase or stage and constraints which may impact any activity.

Float or slack time within the schedule is available without charge or compensation to whatever party or contingency first exhausts it. A schedule which shows a project duration longer than the Contract Time will not be acceptable and will be grounds to consider the Contractor in default of the Contract per 6-4.
The Engineer may cho ose to a ccept the C ontractor’s p roposal of a p roject duration which i s shorter than the C ontract time provided the sh ortened Basel ine Constru ction Schedule i s reasonable and demonstrates, to the satisfaction of the Eng ineer, that the Agency and all other entities, public and private, which interface with the project are able to support the provisions of the shortened sc hedule. Acceptance of a s hortened Baseline Co nstruction Schedule will be confirmed through the execution of a Change Order revising the Contract time.
The Eng ineer’s approval of the Bas eline C onstruction Schedule is a condition precedent to issuance of the Notice to Pr oceed. If t he schedule does not meet the requirements of these specifications, the Contractor shall revise the schedule and resubmit it to the Engineer. Failure to obtain the Engineer’s approval of the schedule within fifteen (15) working days after the date of the pr econstruction me eting shall b e grounds to c onsider the Contractor in default of t he Contract per 6-4. The number of working days used by t he Engineer to review the initial Baseline Co nstruction Schedule s ubmittal will not be include d i n the 15 working day s. The Engineer s hall complete subsequent revi ews of the revised schedule and progress updates within 5 working days of receipt. The Engineer’s response to each review will consist of one of the following:
“Accepted.” The Contractor may proceed with the W ork upon issuance of the Notice t o Proceed. Pa yment for the schedule may be r equested by the Contractor.
“Accepted with Com ments.” The Contractor may proceed wi th the Work upon issuance of the Notice to Proceed. The Contractor must revise and resubmit the schedule and receive the Engineer’s acceptance of the schedule before payment for the schedule is requested by the Contractor.
“Not Accepted.” The Contractor may not proceed with the Work, must revise and resubmit the schedule and may not request payment for the schedule.
6-1.1.2 Schedule Updates and Revisions. The Contractor shall meet with the Engineer during the last week of each month to agree upon the completion level of each activity as a b asis for progress payments. Schedule updates shall conform wi th th e requirements for t he initia l submittal in 6-1.1.1 and shall:

The Engineer’s responses to the progress schedule updates shall be as described in 6-1.1.1.
The Contractor shall proceed with Work and request payment fo r the progress schedule updates as described therein.
If the Contrac tor fails t o submit the progress schedule updates as required herein, the Contractor may elect to pr oceed with the Work at its o wn risk and shall forfeit payment for th e progress schedule update until compliance is met. If the Con tractor elects to delay or cease Work after failure to submit the pr ogress sche dule upd ates, a ny res ulting delay, impact, or disruption to the Work will be the Contractor’s responsibility.
6-1.1.3 Interim Revisio ns. Should the actual or project ed progress of the Work exceed 5 percent of the Contract Time, the Contractor shall prepare and submit a revised Ba seline Construction Schedule independently of and prior to the next progress schedule update with a list and explanation of each change made to the schedule. The submittal, schedule review and acceptance requirements of 6-1.1.2 shall apply,
6-1.1.4 Late Completion or Milestone Dates. If a schedule update indicates a completion date later than the Contract time or co ntractually required milest one completion date, the Agency may withhold Liquidated Damages for the number of days late. Should a subsequent schedule update which removes all or a portion of th e delay be “Accepted” by the Engineer, all or the allocated portion of the p reviously held Liquidated Damages shall be released in the mont hly payment to the Contractor immediately following such acceptance.
6-1.1.5 Final Sched ule Upda te. The Contractor s hall p repare and submit a final schedule update wh en one hu ndred percent of the Work is com pleted. The update must ac curately represent the actual dates for all activities. The fina l schedule upda te sha ll b e prepare d and reviewed in ac cordance with 6-1.1.2.

1. INTRODUCTION
This report presents the results of the geotechnical services Atlas performed for the subject project. It is our understanding that the project will consist of the design and construction of new sewer pipeline segments at both the Tyler Street and Pio Pico sites in Carlsbad, California.
Figure 1 presents the site vicinity.
2. SCOPE OF WORK
2.1 Investigations and Monitoring Wells
Atlas performed a geotechnical investigation to address geotechnical issues pertaining to the design and construction of the subject projects and evaluate impacts of groundwater during the proposed constructions. Pertinent documents reviewed included published reports and maps, aerial photographs, and other readily available documents. On August 14, 2023, Atlas explored subsurface conditions at the Pio Pico Drive site by drilling one boring (B-1) to a depth of approximately 20 feet below the existing ground surface using a truck-mounted drill rig equipped with a hollow-stem auger. Afterwards, on August 25, 2023, Atlas investigated subsurface conditions at the Tyler Street site by drilling one boring (MW-1) to a depth of approximately 26 feet below the existing ground surface using a limited access drill rig (LAR) equipped with a hollow- stem auger. Boring MW-1 at the Tyler Street site was subsequently converted to a groundwater monitoring well with flush mount and traffic-rated well completion box. Figures 2A and 2B present the approximate locations and depths of the boring and monitoring well at the Pio Pico and Tyler Street sites, respectively.
An Atlas engineer and geologist logged the borings and collected samples of the materials encountered for geotechnical laboratory testing. Subsurface materials recovered during the field investigation were observed in the field for soil and/or groundwater contamination with visual and olfactory methods. Soils were classified according to the Unified Soil Classification System illustrated in the Subsurface Exploration Legend. The boring logs are presented in Appendix I.
2.2 Laboratory Testing
Selected samples from the exploratory borings were tested to evaluate pertinent soil classification. The laboratory testing performed on soil materials consisted of in-situ moisture and density, particle-size distribution, percent finer than #200 sieve, direct shear, R-value, expansion index, and corrosivity. The results of the in-situ moisture and density tests are presented on the boring logs in Appendix I. The remaining laboratory testing standards and results are presented in Appendix II.
2.3 Environmental Screening
Atlas collected representative groundwater samples from the monitoring well at Tyler Street in accordance with the County of San Diego Department of Environmental Health and Quality
Atlas No. 10206
Report No. 1
Page | 2
(DEHQ) Site Assessment and Mitigation (SAM) Manual guidelines. The groundwater samples were analyzed for potential detectable concentrations of chemicals and metals of concern including oil and grease, volatiles, semi volatiles, volatile organic compounds, pesticides, and California Title 22 Metals (including mercury and boron). Additionally, the groundwater samples were analyzed for total suspended solids, total dissolved solids, and biochemical oxygen demand.
The collected samples were decanted into pre-cleaned, laboratory-supplied jars and placed in an ice chilled cooler. The samples were transported, under appropriate chain-of-custody protocols, to Eurofins/Calscience, Inc., a State of California accredited laboratory, for analysis. The environmental laboratory reports are presented in Appendix III.
2.4 Analysis and Report Preparation
The results of the field and laboratory tests were evaluated to develop conclusions and recommendations, including the following:
• A plot plan showing the boring locations
• Exploration logs with soil characterization descriptions detailing the subsurface conditions noted at the boring locations
• Describe subsurface geologic conditions as well as groundwater levels observed • Potential geologic hazards including liquefaction
• Map seismic design parameters in accordance with 2022 CBC • Results of the groundwater sampling and analysis
• Excavation characteristics of the subsurface materials encountered • Backfill recommendations and the suitability of excavated materials for use as backfill and bedding
• Allowable temporary excavation side slope and shoring design recommendations • Underground structures foundation
• Support for pipeline
• Appropriate types of bedding and backfill materials as well as placement and compaction procedures
• Subgrade compaction beneath pavements
• Pavement structural sections
• Corrosivity of earth materials
3. SITE DESCRIPTION
The two project alignment segments are located along Pio Pico Drive and Tyler Street in Carlsbad, California. The Pio Pico Drive site is located on Pio Pico Drive between Tamarack Avenue and Magnolia Avenue. Furthermore, the site is adjacent to St. Patrick’s Catholic School and extends
Atlas No. 10206
Report No. 1
Page | 3
roughly from the school’s southern edge to its northern edge. The site topography is characterized by a level asphalt-paved roadway with curbs, gutters, and pedestrian sidewalks found on either side of the roadway. The site elevations range from approximately 68 feet above mean sea level (AMSL) to 71 feet AMSL.
The Tyler Street site is located along Tyler Street north of Grand Avenue between State Street and Roosevelt Street. The site is bounded to the south by the intersection between Grand Avenue and Tyler Street and extends from that intersection roughly 290 feet north. Topographically, this site is flat and is located along an alleyway surrounded by one and two-story buildings such as shops, restaurants, and the local Certainty Theater. The general site elevation is approximately 43 feet AMSL. The alley way is mostly paved with asphalt, with a width of about 25 feet.
4. GEOLOGY AND SUBSURFACE CONDITIONS
The site is located within the Peninsular Ranges Geomorphic Province of California, which stretches from the Los Angeles basin south into Baja California. This province is characterized as a series of northwest-trending mountain ranges separated by subparallel fault zones and a coastal plain of subdued landforms. The mountain ranges are underlain primarily by Mesozoic metamorphic rocks that were intruded by plutonic rocks of the southern California batholith, while the coastal plain is underlain by subsequently deposited marine and non-marine sedimentary formations. Both project sites are located in the coastal plain. Figure 3 presents the regional geology. Descriptions of the materials encountered are provided in the following sections.
4.1 Pio Pico Drive Site
Fill (Qf) was encountered in boring B-1 below the existing ground surface and extends to a depth of approximately 5 feet below existing ground surface (bgs). The fill materials encountered generally consisted of moist, medium dense silty sand.
Old paralic deposits (Qop) deposits were encountered below the fill and extend to the maximum depth explored of 20 feet bgs at this location. The materials encountered generally consisted of moist, very dense silty sand underlain by moist, dense poorly graded sand with clay underlain by moist, very dense clayey sand and sandy silt.
4.2 Tyler Street Site
Fill (Qf) was encountered in boring MW-1 below the existing ground surface and extends to a depth of approximately 7 feet bgs. The fill mater ials encountered generally consisted of moist, medium dense to dense silty sand.
Old paralic deposits (Qop) deposits were encountered below the fill and extend to the maximum depth explored of 26 feet at this location. The materials encountered generally consisted of moist, medium dense clayey sand, underlain by moist to wet hard sandy lean clay and dense poorly graded sand underlain by wet, very dense silty sand and silt.
Atlas No. 10206
Report No. 1
Page | 4
5. GROUNDWATER CONDITIONS
Groundwater was not encountered in boring B-1 to the maximum drilled depth of about 20 feet bgs. However, review of available historical data indicates that groundwater was estimated to be as shallow as 20 feet bgs in the vicinity of boring B-1 (SGMA, 2019).
Groundwater was encountered in boring MW-1 during the drilling operation at a depth of about 13 feet bgs. To assist in assessing groundwater levels during construction, a temporary groundwater monitoring well was installed at boring MW -1 to observe the groundwater activity.
Observed groundwater levels at the time of the well construction and during the first monitoring event are shown in Table 1. The groundwater levels will be recorded at MW-1 during a second monitoring event as well at a date to be coordinated by the project team. A diagram presenting the well construction is provided in Appendix I.
It should be recognized that groundwater conditions may vary at a site over time. Fluctuations in the groundwater level may occur due to variations in ground surface topography, subsurface geologic conditions and structure, rainfall, irrigation, broken pipes, changes in site drainage, and other factors. These types of conditions can be most effectively assessed at the time of construction.

6. GEOLOGIC HAZARDS
6.1 Faulting and Surface Rupture Hazard
As defined by the State of California, surface fault rupture is the result of fault movement that breaks the ground surface (CGS, 2023). The State of California has classified fault zones into three categories. Holocene Active faults are those that have shown conclusive evidence of faulting during the Holocene Epoch (the most recent 11,700 years). Pre-Holocene faults are any fault whose recency of past movement is older than 11,700 years. Age-undetermined faults are faults that are unconstrained by dating methods and/or by limitations in stratigraphic resolution (CGS, 2023). Holocene active faults are regulated by the Alquist-Priolo Earthquake Fault Zoning Act.
The sites are not located in the Alquist-Priolo Earthquake Fault Zone. Based on our review of the referenced documents and aerial photography, site observations, and our field investigations no
Atlas No. 10206
Report No. 1
Page | 5
active faults are known to underlie or project toward the sites. The probability of fault rupture affecting the sites is considered low.
The closest known active fault to both sites is the Newport-Inglewood-Rose Canyon Fault Zone which is located approximately 4.7 and 4.4 miles southwest of the Pio Pico and Tyler Street project sites, respectively. Figure 4 presents the approximate site location overlain on the California fault activity map.
6.1.1 CBC Seismic Design Parameters
A geologic hazard likely to affect the projects is ground shaking due to movement along an active fault zone in the vicinity of the subject sites (USGS, 2022). Based on the subsurface conditions encountered during our investigation, both project sites may be classified as Site Class D. The mapped site coefficients as well as design and maximum considered earthquake (MCE R) spectral
response acceleration parameters in accordance with ASCE 7-16 (ASCE, 2023) are presented in Table 2. The mapped acceleration parameters can only be used if the exception of increasing S M1
by 50% is followed, as described in Section 11.4.8 in Supplement 3 of ASCE 7-16.

(1) Mapped spectral response accelerations parameters were obtained from ASCE7 Online Hazard Tool (ASCE, 2023). (2) Mapped ground acceleration parameters can only be used if the exception described in Supplement 3 of ASCE 7-16 is followed.
6.1.2 Liquefaction and Dynamic Settlement
Liquefaction occurs when loose, saturated, generally fine sands and silts are subjected to strong ground shaking. The soil loses shear strength and become liquid, potentially resulting in large total and differential ground surface settlement as well as possible lateral spread during an
Atlas No. 10206
Report No. 1
Page | 6
earthquake. Liquefiable materials are not mapped along the project alignments. Given the relatively dense soils below groundwater, it is our opinion that the potential for liquefaction and dynamic settlement to significantly impact the proposed projects is considered low.
6.1.3 Tsunamis, Seiches, and Flooding
The site is not located within a mapped area on the State of California Tsunami Inundation Maps (Graehl and Wilson, 2022); therefore, damage due to tsunamis is considered low. Seiches are periodic oscillations in large bodies of water such as lakes, harbors, bays, or reservoirs. The site is not located adjacent to lakes, ponds, or other confined bodies of water; therefore, the potential for a seiche to affect the site is considered negligible. The site is not located within a flood zone (County, 2019) or dam inundation area (DWR, 2023).
6.1.4 Landslides and Slope Stability
Evidence of landslides, deep-seated landslides, or slope instabilities was not observed at the time of our field evaluation. Additionally, there are no mapped landslides in the vicinity of the project site (CGS, 2023). The potential for landslides or slope instabilities to occur at the site is considered low.
6.1.5 Subsidence
The project is not located in an area of known subsidence associated with fluid withdrawal (groundwater or petroleum) (USGS, 2023). Due to this, as well as the presence of relatively dense deposits, the potential for subsidence is low.
6.1.6 Hydro-Consolidation
Hydro-consolidation can occur in recently deposi ted sediments (less than 10,000 years old) that were deposited in a semi-arid environment. Examples of such sediments are eolian sands, alluvial fan deposits, and mudflow sediments deposited during flash floods. The pore spaces between the particle grains can re-adjust when inundated by groundwater, causing the material to consolidate. Due to the relatively dense and moist nature of the material encountered beneath the site, the potential for hydro-consolidation occurrence in the subsurface layers is considered low.
7. CONCLUSIONS
In our opinion, the site conditions are suitable to carry out the proposed project objectives. The main geotechnical considerations affecting the planned development are excavation in dense to very dense subsurface materials at both sites and the presence of shallow groundwater at the Tyler Street site. Based on the current groundwater condition, dewatering should be anticipated at the time of construction. A licensed hydrogeologist should evaluate the appropriate method for dewatering. Additionally, the results of the environmental laboratory testing performed on groundwater samples from monitoring well MW-1 are presented in Appendix III.

8. RECOMMENDATIONS
The remainder of this report presents recommendations regarding earthwork construction as well as preliminary geotechnical recommendations for the design of the proposed improvements.
These recommendations are based on empirical and analytical methods typical of the standard- of-practice in southern California. If these recommendations appear not to address a specific feature of the project, please contact our office for additions or revisions to the recommendations.
8.1 Earthwork
Grading and earthwork should be conducted in accordance with the local standards and the recommendations of this report. The following recommendations are provided regarding specific aspects of the proposed earthwork construction. These recommendations should be considered subject to revision based on field conditions observed by our office during construction.
8.1.1 Site Preparation
Site preparation should begin with the removal of existing improvements, vegetation, and debris.
Subsurface improvements that are to be abandoned should be removed, and the resulting excavations should be backfilled and compacted in accordance with the recommendations of this report. Pipeline abandonment can consist of capping or rerouting at the project perimeter and removal within the project perimeter. If appropriate, abandoned pipelines can be filled with grout or slurry as recommended and observed by the geotechnical consultant.
8.1.2 Excavation Characteristics
It is anticipated that excavations can be achieved with conventional earthwork equipment in good working order. Difficult excavation should be anticipated within the old paralic deposits due to the dense materials encountered as well as caving susceptibility below groundwater. A contractor with excavation experience in similar conditions should mobilize equipment capable of excavating dense granular materials with potential cobbles, provide means to prevent caving and sloughing below groundwater levels, and to anticipate wet subgrade soils.
8.1.3 Oversized Material
Excavations may generate oversized material. Oversized material is defined as rocks or cemented clasts greater than 6 inches in largest dimension. Oversized material should be broken down to no greater than 3 inches in the largest dimension for use within non-structural fill, such as landscape fill, or disposed of offsite in accordance with regulatory requirements.
8.1.4 Temporary Excavations
Temporary excavations 4 feet deep or less can be made vertically. Temporary excavations deeper than 4 feet should not be steeper than 1½:1 (horizontal: vertical), per Cal/OSHA Type C soil classification. The faces of temporary slopes should be inspected daily by the contractor’s competent person before personnel are allowed to enter the excavation. Zones of potential
Atlas No. 10206
Report No. 1

instability, sloughing, or raveling should be brought to the attention of the engineer and corrective action implemented before personnel begin working in the trench.
Slopes steeper than those described above will require shoring. Soldier piles and lagging, corrugated metal pipe, internally braced shoring such as trench boxes or speed shoring could be used. If trench boxes or corrugated metal pipe are used, the soil immediately adjacent to the shoring is not directly supported. Ground surface deformations adjacent to the excavation could be greater when these methods are used compared to other methods of shoring leading to distress to overlying improvements.
If open trenches are to be maintained during the rainy season, berms are recommended along the tops of the trenches to prevent runoff water from entering the excavation.
8.1.5 Temporary Shoring
For design of cantilevered shoring, an active soil pressure equal to a fluid weighing 40 pounds per cubic foot (pcf) can be used for level retained ground or 65 pcf for 2:1 (horizontal:vertical) sloping ground. A passive soil pressure equal to a fluid weighing 300 pcf can be used for the design of cantilevered shoring with the maximum embedment depths above the groundwater level. The passive pressure should be reduced by one half below the groundwater table. 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. Earth pressure diagram is presented in Figure 5.
8.1.6 Temporary Dewatering
During our geotechnical investigation, groundwater was observed as shallow as 13 feet bgs at the monitoring well in Tyler Street (see Table 1). Available literature indicates the groundwater could be shallower than approximately 10 feet at the Tyler Street site. Additionally, groundwater seepage may occur locally along the project alignment due to local irrigation or following heavy rain. Shallow groundwater may impact project construction. An experienced and qualified specialty contractor should evaluate the need and design of a dewatering system, as appropriate.
The contractor’s geotechnical engineer should review proposed dewatering system designs.
8.1.7 Remedial Grading
We recommend that remedial grading be performed beneath the new sewer lines to improve the pipeline support and reduce the potential for static settlement and pipe breakage. Upon completion of excavation and removal of the existing pipe and fill material, the bottom of excavation should be scarified to the depth of 1 foot, moisture conditioned to near optimum moisture content, and recompacted to 90% maximum dry density (ASTM D1557).
Proposed underground structures foundations can be supported by firm and unyielding old paralic deposits, 2 feet of compacted fill, or stabilized subgrade. If placed on compacted fill, the on-site soils should be excavated to a depth of at least 2 feet below planned subgrade elevation. If competent, formational materials are exposed, excavation need not be performed.
Atlas No. 10206
Report No. 1
Page | 9
An Atlas representative should observe conditions exposed in the bottom of excavations to evaluate whether additional excavation is required. The resulting surface should then be scarified to a depth of 8 inches, moisture conditioned to near optimum moisture content, and compacted to at least 90% relative compaction. The maximum dry density and optimum moisture content for evaluating relative compaction should be obtained using ASTM D1557. For structures with subgrade elevations at or near the groundwater elevation, subgrade shall be stabilized following the recommendations of this report.
8.1.8 Compacted Fill
On-site materials, except for soil containing roots, debris, and rock greater than 3 inches, can be used as compacted fill or trench backfill. Fill and backfill should be placed in horizontal lifts at a thickness appropriate for the equipment spreading, mixing, and compacting the material, but generally should not exceed 8 inches in loose thickness. Fill and backfill should be moisture conditioned within 2% of optimum moisture content and compacted to at least 90% relative compaction. The top 12 inches of subgrade beneath pavement should be compacted to at least 95%. The compacted fill should have an EI of 50 or less. The maximum dry density and optimum moisture content for evaluating relative compaction should be obtained using ASTM D1557.
8.1.9 Expansive Soil
The laboratory results indicate that on-site materials tested are classified as having a very low expansion potential. The grading and foundation recommendations presented in this report assume materials with a low expansion potential.
8.1.10 Imported Soil
Imported soil should consist of predominately granular soil, free of organic matter and oversized materials (i.e., rocks larger than 3 inches). Imported soil should be observed and, if appropriate, tested by Atlas prior to transport to the site.
8.1.11 Subgrade Stabilization
In areas where wet, soft, or yielding excavations bottoms are encountered, a geogrid reinforced soil mat could be installed to provide support for proposed subsurface structures foundation construction. To stabilize soft or yielding bottoms, Atlas recommends placing one layer of Tensar® Triax TX-160 reinforcing geogrid or equivalent on the removal surface (e.g., excavation bottom) followed by at least 12 inches of ¾-inch crushed rock compacted using lightweight equipment. The crushed rock layer shall then be overlaid by a second layer of the geogrid followed by minimum 6 inches of aggregate base. Aggregate base section shall then be compacted to a relative compaction of 95%. If yielding is still observed upon proof rolling, an additional layer of geogrid should be placed on the compacted base followed by at least 6 inches of aggregate base.
Crushed rock and aggregate layers shall be covered and wrapped (on both sides and above the layer) with a nonwoven filter fabric such as Mirafi-140N, or equivalent to avoid siltation and segregation.
Atlas No. 10206
Report No. 1
Page | 10
The above recommendations are only valid when the depth of the groundwater is below the compacted aggregate base layer. In circumstances where the aggregate base layer is below the groundwater table, it is recommended to replace the compacted aggregate base layer with 12 inches of crushed rock to avoid pumping and disintegration of the aggregate base.
8.1.12 Grading Plan Review
Atlas 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.
8.2 Pipelines
8.2.1 Pipeline Support
It is anticipated that most of the materials along the pipeline alignment will provide adequate support for the pipe, although loose, soft, and otherwise unsuitable materials could be encountered. Unsuitable materials encountered near trench bottom levels should be excavated to competent material as determined by the geotechnical consultant. The excavated materials can be replaced with compacted fill or with pipe bedding material, as described below. Unsuitable materials should be removed from the full width of the trench. The bottoms of the excavations should be observed by the geotechnical consultant prior to placement of pipe bedding.
8.2.2 Trench Backfill
Utility trench sections should conform to the minimum requirements of the City of Carlsbad and other local jurisdictions. Backfill should be placed in loose lifts not exceeding 6 to 8 inches in thickness, moisture conditioned to near optimum m oisture content, and compacted to at least 90% relative compaction.
On-site materials, except for soil containing roots, saturated soils, debris, and rock greater than 6 inches, can be used as compacted fill or trench backfill, provided that they have an expansion index of 50 or less. The maximum dry density and optimum moisture content for the evaluation of relative compaction should be determined in accordance with ASTM D1557.
8.2.3 Pipe Bedding
Pipe bedding as specified in the “Greenbook” can be used. Bedding material should consist of clean sand having a sand equivalent not less than 30 and should extend to at least 12 inches above the top of pipe. Alternative materials meeting the intent of the bedding specifications are also acceptable. Samples of materials proposed for use as bedding should be provided to the engineer for inspection and testing before the material is imported for use on the project. The on- site materials are not expected to meet “Greenbook” bedding specifications. The pipe bedding material should be placed over the full width of the trench. After placement of the pipe, the bedding should be brought up uniformly on both sides of the pipe to reduce the potential for unbalanced

loads. No voids or uncompacted areas should be left beneath the pipe haunches. Ponding or jetting the pipe bedding should not be allowed.
8.2.4 Thrust Blocks
For level ground conditions, a passive earth pressure of 330 pounds per square foot (psf) per foot of depth below the lowest adjacent final grade can be used to compute allowable thrust block resistance. A value of 140 psf per foot should be used below groundwater level, if encountered.
8.2.5 Modulus of Soil Reaction
A modulus of soil reaction (E’) of 1,000 pounds per square inch can be used to evaluate the deflection of buried flexible pipelines. This value assumes that granular bedding material is placed adjacent to the pipe and is compacted to at least 90% relative compaction.
8.3 Underground Structures
8.3.1 Foundations
The planned underground structures (i.e., vaults, manholes, etc.) can be supported on mat foundations with bottom levels on compacted fill, reinforced geogrid mats, or competent formational material.
Thickness and reinforcement of the mat foundation should be in accordance with the recommendations of the project structural engineer. Mat foundations typically experience some deflection due to loads placed on the mat and the reaction of the soils underlying the mat. A design modulus of subgrade reaction, K, of 150 pounds per cubic inch (pci) may be used in evaluating such deflections on subgrade soils recommended in this report. These values are based on an area of one square foot and should be adjusted for large mats. Adjusted values of the modulus of subgrade reaction, K
BxB, can be obtained from the following equation for square mats of various widths:

where, B is the width of the mat in feet.

where, B is the width and L is the length of the mat in feet.

Page | 12
8.3.2 Allowable Soil Bearing Pressure
Since the weight of soil removed during excavation will be greater than or approximately equal to the weight of the new construction and backfill, we do not expect foundation bearing capacity to be a significant geotechnical design concern. The planned subsurface structures can be supported on mat foundations with bottom levels on compacted fill, reinforced geogrid mats, or competent Very Old Paralic deposits. An allowable bearing capacity of 2,500 psf can be used.
The bearing value can be increased by ⅓ when considering short term loads.
8.3.3 Lateral Resistance
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. A coefficient of friction of 0.35 can be used. Passive pressure can be computed using a lateral pressure value of 300 psf per foot of depth below the ground surface and above groundwater level for level ground conditions.
Passive pressure shall be reduced to 150 for the structures below groundwater level. Reductions for sloping ground should be made. The passive pressure can be increased by ⅓ when considering the total of loads, including wind or seismic forces. The upper 1 foot of soil should not be relied on for passive support unless the ground is covered with pavements or slabs. The lateral passive earth pressure values provided herein are ultimate values and appropriate factor of safety shall be applied.
8.3.4 Underground Structures Backfill
The underground structures backfill should consist of granular, free-draining material having a sand equivalent of 20 or more. Additionally, fill within 3 feet from the back of the wall should not contain rocks greater than 3 inches in any dimension. The backfill zone is defined by a 1:1 plane projected upward from the bottom of the foundation. Clayey soils and/or fine-grained materials with Expansion Index greater than 50 should not be used. Material to be used for backfill should be compacted to at least 90% relative compaction. Backfill should not be placed until the concrete walls have achieved adequate structural strength. Compaction of the backfill will be necessary to minimize settlement of the backfill and overlying settlement-sensitive improvements. However, some settlement should still be anticipated. Alternatively, a controlled low-strength material such as sand cement slurry may be considered for backfill. The controlled low-strength material should be thoroughly consolidated, have a maximum slump of 4 inches, and the slurry should meet the requirements of the local authority with jurisdiction. Atlas representative should observe the wall backdrain installations and wall backfill process.
8.3.5 Foundation Plan Review
Atlas 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.
Atlas No. 10206
Report No. 1

8.3.6 Foundation Excavation Observation
A representative from Atlas should observe the foundation excavations prior to forming or placing reinforcing steel.
8.4 Preliminary Pavement Section Recommendations
The on-site soils tested have R-values of 71 and 86. The actual R-value of the subgrade soils should be determined after grading, and the final pavement sections should be provided based on the final results. An R-value of 50 and assumed Traffic Indexes of 6, 7, and 8 were used for the design of preliminary pavement sections. Table 3 presents recommended flexible and rigid structural sections for the assumed Traffic Indexes and subgrade R-value:

7.0 4 over 5 7 7
8.0 5 over 6 8 7
(1) AC: Asphalt Concrete
(2) AB: Aggregate Base
(3) PCC: Portland Cement Concrete
The top 12 inches of subgrade beneath pavements should be scarified, moisture conditioned to near optimum moisture content, and compacted to at least 95% relative compaction (ASTM D1557). Soft or yielding areas should be removed and replaced with compacted fill or aggregate base. Aggregate base and asphalt concrete should conform to the Caltrans Standard Specifications and should be compacted to at least 95% relative compaction. Aggregate base should have an R-value of not less than 78. All materials and methods of construction should conform to good engineering practices and Caltrans standard specifications.
8.5 Soil Corrosivity
Representative samples of the on-site soils were 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. For structural elements, the California Department of Transportation considers a site to be corrosive if one or more of the following conditions exist for the representative soil and/or water samples taken at the site: Chloride concentration is 500 ppm or greater, sulfate concentration is 1,500 ppm or greater, or the pH is
5.5 or less. Based on these criteria the tested on-site soils are not considered corrosive to structural elements. A corrosion engineer should be contacted to provide specific corrosion control recommendations.

8.6 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. Atlas recommends a geotechnical engineer or engineering geologist be on site to observe trenching operations. 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.
9. CLOSURE
Atlas should be advised of 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 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 entirely 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 profess ion 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.

Relatively undisturbed samples were obtained using a modified California (CAL) sampler, which is a 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 1 ⅜-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 boring logs as “Driving Resistance (blows/ft. 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. The SPT penetration resistance was normalized to a safety hammer (cathead and rope) with a 60% energy transfer ratio in accordance with ASTM D6066. The normalized SPT penetration resistance is noted on the boring logs as “N
60.” Disturbed bulk samples were obtained from the SPT sampler and the drill cuttings. The soils are classified in accordance with the Unified Soil Classification System.
A temporary groundwater monitoring well was installed at the Tyler Street boring location to monitor groundwater levels over time. The groundwater levels will be recorded during a second monitoring event as well at a date to be coordinated by the project team. A diagram presenting the well construction is presented in Appendix I.

LABORATORY TESTING
Laboratory tests were performed to provide pertinent geotechnical parameters for engineering analyses associated with the proposed improvements. The following tests were conducted:
• CLASSIFICATION: Field classifications were verified in the laboratory by visual examination. The final soil classifications are in accordance with the Unified Soil Classification System.
• IN-SITU MOISTURE AND DENSITY: The in-situ moisture content and dry unit weight were evaluated on selected samples collected from the borings. The test results are presented on the boring logs in Appendix I.
• PARTICLE-SIZE DISTRIBUTION: The particle-size distribution was evaluated on selected soil samples in accordance with ASTM D6913.
• PERCENT FINDER THAN #200: The percent of materials finer than No. 200 sieve (75µm) was measured on selected samples in accordance with ASTM C117 and ASTM D1140. • EXPANSION INDEX: This test was performed on selected soil samples in accordance with ASTM D4289.
• DIRECT SHEAR: This test was performed on a selected soil sample in accordance with ASTM D3080. The shear stress was applied to inundated samples at a constant rate of strain of 0.003 inch per minute.
• R-VALUE: This test was performed on selected soil samples in accordance with Caltrans Test Method 301.
• CORROSIVITY: Corrosivity tests were performed on selected soil samples. The pH and minimum resistivity were evaluated in general accordance with California Test 643. The soluble sulfate content was evaluated in accordance with California Test 417. The total chloride ion content was evaluated in accordance with California Test 422.
Soil samples not tested are stored in our laboratory for future reference and analysis, if needed.
Unless notified to the contrary, all samples will be disposed of 30 days from the date of this report.
