FROM: Sean Corrigan, City Engineer/Public Works Director
DATE: 03/04/2020 Regular Meeting
SUBJECT: Consider Amendment No. 8 to Agreement Between the City of
Moorpark and Stantec Consulting Services, Inc. for the Re-Design of
the Princeton Avenue Improvement Project (C0020)
SUMMARY
On March 19, 2008, the City Council approved an agreement for civil engineering
design services with Penfield & Smith, in an amount not-to-exceed $279,148, to provide
conceptual and final design for the Princeton Avenue Improvement Project (C0020).
Since the original contract agreement, the Princeton Avenue Improvement Project has
required several contract amendments to augment Penfield & Smith’s scope of
services, including their name change to Stantec Consulting Services, Inc. The current
contract value is $936,638.25.
Stantec Consulting, on behalf of the City, is currently processing Project Plans and
Specifications through Caltrans District 7 Office of Permits to obtain plan approval and
an encroachment permit for the proposed improvements within State right-of-way.
During the plan review process, Caltrans staff is requesting additional information and
design data that require further evaluation by Stantec and staff, including a new
retaining wall. Based on this request, Stantec provided a cost proposal for the
additional services and Amendment No. 8 is attached for the City Council’s
consideration and approval.

DISCUSSION
The project limits for the Princeton Avenue Improvement Project is along Princeton
Avenue, approximately 1,500 feet east of Spring Road to Condor Drive. A portion of the
proposed improvements is within State right-of-way, as it crosses underneath State
Highway 118, and requires Caltrans review and oversight. Stantec Consulting, on
behalf of the City, is currently processing Project Plans and Specifications through
Caltrans District 7 Office of Permits to obtain plan approval and an encroachment permit
for the proposed improvements within State right-of-way.

Figure 2. Portion of Project within State Right-of-Way
The back and forth plan review and approval process with Caltrans Office of Permits is
for proposed improvements within the State right-of-way only and includes new
retaining walls, pavement section and widening, utilities, and maintenance and
protection of State facilities, including the bridge structures that support State Highway
118. Staff initiated the plan review process with the first submittal on October 3, 2018,
and subsequent plan review submittals on March 15, 2019, and on October 3, 2019.
During each plan review submittal, staff received many comments from all reviewing
disciplines within the Caltrans organization. Most technical design comments have
been adequately addressed by Stantec. There are a few design comments that require
further evaluation by Stantec and staff and are as follows:
• Updated utility research;
• Geometric analysis of the existing alignment versus proposed design as it relates
to the design speed along Princeton Avenue;
• Design changes to proposed retaining walls per Caltrans comments, including a
new retaining wall;
• Update drainage plans with revised storm drainage infrastructure and hydraulic
calculations;
• Additional pavement analysis of the existing road section;
• Field testing to conduct a Limited Soil Screening for Asbestos Containing
Materials (ACM) and Lead Based Paint (LBP);
• And, additional geotechnical investigation and groundwater sampling for the new,
proposed retaining wall.

Moorpark, CA 93021
Reference: Princeton Avenue Widening Project 8012, Proposal for Additional Services - Change
Order 8
Dear Mr. Corrigan,
Our office prepared the last project budget amendment for the Princeton Avenue project in July
of 2018. Since that time, a number of unanticipated additional services have been requested by
City staff or have become necessary as a result of project review by Caltrans. Per our recent
meetings and discussions, we are pleased to present this proposal to address those additional
services for the subject project.
ADDITIONAL SCOPE OF SERVICES
Task 1 – Updated Utility Research/Electrical Exhibit
The City has requested that Stantec provide an Electrical Plan depicting the public and private
electrical facilities throughout the project area. Additionally, because the initial utility research for
the project was completed over ten years ago, it is appropriate at this time to request new atlas
mapping from the utility companies and update the project base mapping.
a. Research current utility providers in the project vicinity.
b. Send utility infrastructure requests to area utility providers to obtain current atlas mapping
of their facilities in the project vicinity.
c. Compare information received against prior mapping and update as needed.
d. Prepare detailed electrical exhibit showing existing facilities, proposed facilities and
facilities to be removed or relocated.
Task 2 – Caltrans Design Documentation
The encroachment permit package has been submitted to Caltrans for a third time after addressing
the recently received second round of plan check comments. In their comments Caltrans has
questioned the overall design speed and horizontal alignment of the project. Although the project
Exhibit A
85

Princeton Avenue Widening Project 8012, Proposal for Additional Services, Change Order 8
Page 2 of 5
geometry was vetted during the environmental review process many years ago, it is necessary at
this time to provide a detailed response to Caltrans.
a. Review design speed/alignment comments and coordinate on a response with City staff
b. Research past project documentation including Initial Study, Mitigated Negative
Declaration and other pertinent files previously provided to Stantec
c. Prepare a written response to design speed/alignment comments
d. Coordinate with City Staff to provide response to Caltrans for their concurrence
e. Participate in meetings and prepare final Design Decision Memorandum and submit to
Caltrans with 3rd plan check submittal.
Task 3 – Caltrans Retaining Walls
Through the encroachment permit process, Caltrans is requiring significantly more design changes
to the project than previously anticipated. Caltrans is requiring that walls be designed per AASHTO
(rather than CBC) and that an additional retaining wall be included in the project in order to avoid
earth fill being placed against their existing facilities. The required wall (Wall “J”) will be an up to 17-
foot tall, pile-supported wall, constructed of slumpstone CMU block (where visible), and will include
a concrete traffic barrier adjacent to the roadway.
a. Research Caltrans record drawings to determine layout and extents of existing facilities to
be protected.
b. Prepare a schematic wall layout and structural section based on site constraints for review
by City staff
c. Prepare final design of walls including specifications and structural calculations per
AASHTO requirements.
d. Prepare plan and profile, details and notes for the added walls and incorporate into the
project plans.
e. Wall “C”, which is already part of the project design, will be redesigned per AASHTO
standards.
f. Prepare a separate submittal package to be provided to Caltrans addressing only the
walls that within Caltrans right-of-way (Wall “C” and Wall “J”).
Task 4 – Additional Caltrans Design Revisions
Caltrans has required several changes to the proposed drainage design including elimination of an
existing storm drain which was discharging in their right-of-way. These changes have had a ripple
effect on the design which has resulted in additional storm drain, grading and wall revisions within
Caltrans right of way, beyond the scope originally anticipated.
86
December 9, 2019
Princeton Avenue Widening Project 8012, Proposal for Additional Services, Change Order 8
Page 3 of 5
a. Determine feasible alternatives to eliminating existing storm drain line “X-1” due to Caltrans
plan check comments.
b. Update Wall C profile to account for elimination of line “X-1”, add additional gutter wall
drains to redirect drainage.
c. Delineate new drainage subareas based on revised design and calculate design flows for
each facility.
d. Revise hydraulic calculations of all affected storm drain facilities and prepare new
hydraulic calculations for new facilities and update drainage report.
e. Update plan set with new hydraulic data (flow and velocity) for storm drain facilities.
f. Incorporate all revisions into project drainage study and issue new study for submittal to
Caltrans and City.
Task 5 – Existing Pavement Analysis/Documentation
The City has expressed concern about obtaining accurate bids to remove the existing AC
pavement which is underlain by Portland cement concrete (PCC). Our subconsultant, Dynatest
North America, Inc. (Dynatest) will utilize ground penetrating radar (GPR) to determine an estimate
of the thickness and horizontal extent of PCC existing structural section. Their work will be calibrated
using the pavement cores previously extracted by Pavement Engineering Inc. See attached
proposal from Dynatest.
Task 6 – Limited Soil Screening Investigation
Caltrans required investigation of Aerially Deposited Lead (ADL) and an Initial Site Assessment (ISA)
in order to acquire an encroachment permit for work within their Right of Way. Stantec performed
an ISA which has been reviewed and accepted by Caltrans. Based on the findings of the ISA, field
testing is now proposed to conduct a Limited Soil Screening for Asbestos Containing Materials
(ACM) and Lead Based Paint (LBP). See attached proposal from Stantec environmental staff for
details.
Task 7 – Additional Geotechnical Investigation
Caltrans is requiring more accurate information regarding groundwater depth in the vicinity of the
newly proposed Wall J. Also, review of past Caltrans construction documents indicates that depth
to bedrock at this location may be highly variable. As a result, the project geotechnical consultant
(Earthsystems) is proposing to perform three soil borings in the vicinity and provide updated design
parameters for the retaining wall.
87
December 9, 2019
Princeton Avenue Widening Project 8012, Proposal for Additional Services, Change Order 8
Page 4 of 5
Task 8 – Groundwater Sampling (Contingency)
The closest boring to Wall J did not indicate groundwater was found at a depth that would
impact design or construction of the wall. However, if groundwater is encountered during the
geotechnical investigation (Task 7), Caltrans requires that the water be sampled for pollutants so
that removal of the water during construction can be adequately planned for. Should
Earthsystems encounter groundwater during their investigation, Stantec will be notified to collect
and analyze the groundwater and provide direction regarding treatment/disposal of
groundwater during construction.
PROPOSED ADDITIONAL FEE
Our services will be performed on a “time and materials”, not to exceed basis, per the schedule
below and shall be billed monthly at the rates then currently in effect. Our charges will not exceed
the fee estimate without the City’s prior authorization. Public Agency Fees are excluded (e.g.
Caltrans, County of Ventura, Utilities, etc.) shall be the responsibility of the City.
Task No. Task Fees Notes
1 Updated Utility Research/Electrical Exhibit $8,500.00
2 Caltrans Design Documentation $9,500.00
3 Caltrans Retaining Walls $18,000.00
4 Additional Caltrans Design Revisions $15,000.00

REF: FWD and GPR Testing and Analysis on Princeton Ave. in the City of Moorpark, California
Dear Mr. Salts,
Further to your request, Dynatest is pleased to provide the following proposal for non-destructive
deflection testing (NDT) using our Falling Weight Deflectometer (FWD) and Ground Penetrating
Radar (GPR) on Princeton Avenue in the City of Moorpark, California. The objective of the project
is to determine the limits and thickness of the Portland cement concrete (PCC) beneath the
existing asphalt concrete (AC) surface.

Testing will be conducted in both through lanes using a Dynatest Falling Weight Deflectometer
(FWD). We will test at the intervals shown in the table above staggered between through lanes to
obtain a representative coverage of the entire roadway. The approximate total number of test
points is 160 and will take about one (1) day to complete the deflection and GPR testing.
A GSSI SIR30-42000S GPR system will be used to collect pavement layer thicknesses. The GSSI
GPR System SIR30 has 4 channel electronics, a single air launched 2 GHz horn antenna and a 1
GHz ground coupled antenna that are mounted to the front of a vehicle to accurately measure
dielectric constants. Ground coupled GPR can couple more energy into the ground and extract
more energy out of it, which results in clearer data and greater depth of investigation. GPR is
used to determine the pavement thicknesses by means of emitting a series of radar waves to the
pavement structure while the vehicle is traveling at traffic speed. The resulting correlated
dielectric constants are then filtered to determine pavement thicknesses. The results must be
calibrated through pavement cores that provides layer thicknesses and types at selected locations.
Our FWD is fully integrated with the GPR system so that each FWD station corresponds to the
same reading from the GPR system. Furthermore, pavement thicknesses will be reported for
every FWD tested station continuously which in turn increases the accuracy and quality of the
90
Page 2 of 5
pavement evaluation. In addition, by using the GPR technology, there is a significant reduction
in the required number of pavement cores, which in turn translates into savings for the agency
and less traffic disruption.
The deflection data will be normalized to a specific load level and plotted to show the limits of
the PCC beneath the AC surface layer. In general, pavements with PCC will show relatively lower
deflections under the load when compared to AC pavements without PCC.
The GPR data will be analyzed using RADAN 7 software package to estimate the dielectric
properties of the pavement and determine the layer thicknesses.
After performing the deflection testing and Stantec providing us with the thickness and type
information of the different pavement layers, we will provide you with the report that includes
the deflection data, layer thicknesses, and limits of the PCC beneath the AC surface layer.
The evaluation will include the following activities:
Perform nondestructive deflection testing using a Dynatest FWD.
Dynatest will conduct GPR data collection concurrently with the FWD testing to obtain
detailed existing layer thicknesses.
Stantec must provide us with pavement layer thickness and type information from cores.
In addition, any available as-builts and geotechnical reports shall be provided.
Determine the limits of the PCC beneath the AC surface layer.
Provide a report that includes all the analyses results.
We will also perform a limited survey through digital photographs of the pavement, which are
collected during testing. Each FWD test point will be geo-referenced using our sub-meter

Project: Princeton Avenue
Retaining Wall at State Routh 23 Southbound Pier 6L
Moorpark, California
Subject: Proposal to Prepare a Geotechnical Engineering Report
Earth Systems Pacific (Earth Systems) is pleased to present the following as a proposal to prepare a
geotechnical engineering report for a proposed retaining wall to be located on the south side of
Princeton Avenue in Moorpark, California. The wall is part of a road widening project and will keep
a roadside fill from impacting Pier 6L below the southbound lane of Stare Route 23 (SR 23). The wall
will be constructed in the Caltrans State Route 23 right-of-way. The wall will be up to 14 feet tall and
support level backfill. The L-shaped wall is proposed to be constructed on a pile-supported footing
and will require a 1-horizontal to 1-vertical temporary back-cut during construction. It is currently
intended that the piles bear into bedrock.
Prior exploration in the vicinity of the proposed retaining wall have indicated bedrock covered by
about 32 feet of alluvium at Pier 6L of SR 23 and bedrock covered by about 8 feet of alluvium at the
south shoulder of Princeton Avenue. The difference in bedrock elevation is estimated to be 40 feet
in a horizontal distance of about 25 feet and suggests significant changes in the bedrock depth over
small horizontal distances.
Our proposal is divided into three elements, or phases, that correspond to various stages of the
project itself. Phase I of our proposal relates to the geotechnical study and report to be used as a
basis for design; Phase II will address any City review comments, provide consultation with other
design professionals during design, include reviewing grading, retaining wall, and foundation plans,
and providing the Geotechnical Engineer’s sign-off on construction drawings. Phase III is for
construction monitoring. The estimated fee for Phase I is submitted with this proposal. Budgets for
Phases II and III, which are dependent on unknown factors, testing requirements, and a construction
schedule yet to be developed, can be refined and presented for Client approval as the project
progresses.
Earth Systems has developed the following scope of services to generate the Phase I Geotechnical
Engineering Report.

Earth Systems Pacific
A. Earth Systems will begin fieldwork preparation by contacting Underground Service Alert (USA)
and physically marking proposed boring locations so that USA representatives will be able to clear
the site for public utilities. The Client will need to provide Earth Systems with the locations of
any on-site utilities not marked by USA prior to commencement of our drilling activities. Earth
Systems will not be held responsible for damage to any utilities that were not marked or that
were not brought to our attention prior to beginning our drilling activities. The Client will secure
an encroachment permit from Caltrans and supply Earth Systems with permission to enter the
project site.
B. Earth Systems will apply for an Encroachment permit from Caltrans. This will include
electronically submitting an application, an exploration plan, and permit application fee of
$492.00.
C. Earth Systems proposes to drill three soil borings; at the ends and angle point of the proposed
retaining wall foundation. The borings will be drilled to depths of about 30 to 50 feet below the
existing site grade, but not less than 20 feet into bedrock) by the hollow-stem auger methods. A
member of our staff will log the drill holes and supervise the field study. A geotechnical log will
be produced for each boring. Standard penetration and California modified penetration tests
will be performed at regular intervals in the soil borings to assist in evaluating ground conditions
of the subsurface soils and to collect undisturbed samples at the site. Samples will be taken from
the test holes and sealed in containers. The samples will be returned to our laboratory for testing.
If groundwater is encountered, personnel for Stantec will oversee sampling of the groundwater.
The borings will be backfilled with soil and rock cuttings, tamped down periodically during
backfilling. We have assumed that the excess drill cuttings and drill fluids generated during
drilling operations may be disposed of onsite.
D. Laboratory testing will be performed on soil samples collected during the field exploration to help
identify and evaluate subsurface site characteristics. Tests will include, but may not be limited
to: measuring in-place moisture and density; determining the maximum density and optimum
moisture of soils anticipated to be involved in site grading; direct shear testing of undisturbed
and remolded samples of anticipated bearing soils; consolidation testing of in-situ conditions (if
fine-grained soils are encountered); expansion index testing of anticipated bearing soils; grain
size and plasticity index analyses of key soil types; and pH, resistivity, soluble chloride and soluble
sulfate testing of soils anticipated to be in contact with foundations. Testing of groundwater
samples, if acquired, will be the responsibility of Stantec.
E. After field and laboratory tests are complete, the data will be organized and analyzed by a
member of our professional staff to develop conclusions and recommendations relevant to site
development as we understand it.
F. A Geotechnical Engineering Report will be prepared based on evaluation of the data obtained
from the exploration and testing programs, and on experience and judgment. Included in the
report will be descriptions of the field and laboratory tests performed during our studies,
96
December 2, 2019 3 Proposal No.: VEN-19-11-013
Earth Systems Pacific
discussions pertaining to the engineering properties of soil types encountered on-site,
liquefaction potential and other geologic hazards, and recommendations for site development
based on the geotechnical conditions. Recommendations will include: criteria for grading
(including the stability of a 1-horizontal to 1-vertical back-cut), seismic design parameters, pile
design recommendations, and estimated total and differential settlements.
It should be noted that our scope of services will not include any environmental assessment, or
investigation for the presence or absence of wetlands, hazardous or toxic materials in the soil,
surface water, groundwater or air, on, below, or around the subject site.
We feel confident that we can provide the services proposed above in an expeditious manner. Upon
acceptance of this proposal, field work should begin in about two to four weeks (weather and drill
rig availability permitting), and the report should be ready for distribution approximately six weeks
after completion of the field work.
Based on the above, we propose to provide the Geotechnical Engineering Report on a fixed fee basis
for $22,000.00. We intend to issue a 50% invoice of $11,000.00 upon initiation of field work. The
balance of payment will be due and payable upon receipt of the report.
Our reports are intended to address those items required by the City of Moorpark for studies of this
nature. However, the reviewing agencies sometimes request that additional studies be performed
prior to granting approval of a grading or building permit.
Additional services, such as responses to City reviews, plan reviews, meetings, or construction testing
and inspection services, are not included within the scope or fees proposed herein. Such services
would be provided on a Time and Materials basis, as calculated from the Fee Schedule in effect when
the services are provided.
This proposal may be considered valid for a period of 90 days, at which time if it is not fully executed
we reserve the right to modify our proposal in both scope and fee.
TERMS FOR SERVICES
The Mutual Master Services Agreement between Stantec and Earth Systems dated March 16, 2016
will serve as the terms for services for this project phase.

Princeton Avenue, California State Route 118 Overpass
City of Moorpark, California 93021
As requested, Stantec Consulting Services Inc. (Stantec) has prepared this proposal to conduct a Limited
Soil Screening, Asbestos Containing Materials (ACM) and Lead Based Paint (LBP) Investigation for the
City of Moorpark to support the proposed improvements of a section of Princeton Avenue under the
California State Route 118 (SR 118) Overpass in Moorpark, Ventura County, California (Figures 1 and 2
in Attachment A). The construction of the proposed improvements area (PIA) consists of
abandonment/relocation/installation of miscellaneous utility lines, sign posts, and grading of the land
located on the segment of Princeton Avenue owned by State of California, Department of Transportation
(i.e. Caltrans).
SCOPE OF WORK
An Initial Site Assessment (ISA) was conducted by Stantec on January 23, 2019 for the proposed
improvements area and, based on the findings, concluded that the PIA should be investigated for
potential presence of aerially deposited lead (ADL) and other heavy metals in soils. The project is
anticipated to disturb soils up to 2.0 feet below ground surface (bgs) on the north side of the PIA and up
to 4.0 feet bgs on the south side of the PIA. In addition, Stantec also recommended a hazardous material
survey along the metal beam guardrail (MBGR) for shims containing suspect asbestos containing
materials (ACM) and the yellow traffic striping containing suspect lead based paint (LBP) along the
median stripe of Princeton Avenue.
The data from the investigation will be used to evaluate the presence of the constituents of concern
analyzed for, such that the proper disposal and safe handling procedures of soils generated during the
construction activities can be achieved. The results of the investigation will also be used to assist the
contractor in developing an appropriate health and safety plan/Lead Compliance Plan and training
program for the field staff as required per Title 8 of the California Code of Regulations (8CCR) and
California Occupational Safety and Health Administration (Cal OSHA) Construction Safety Order.

TASK – LIMITED SOIL SCREENING, ACM AND LBP INVESTIGATION
Limited Soil Screening
As part of the limited soil screening investigation, soil samples will be collected from hand auger and/or
sampling spade for laboratory analysis. It is assumed that groundwater will not be encountered. Boring
locations are assumed to be in unpaved areas. Boring locations that are located in paved areas will be
relocated to the nearest area of exposed soils.
The construction footprint proposed for the roadside modifications within the PIA does not exceed 2.0 feet
of soil disturbance on the north side and 4.0 feet on the south side. This proposed scope of work is
intended to evaluate whether excavated soil generated during the proposed construction activities will
result in the need for special handling for disposal (as defined by Title 22 of the California Code of
Regulations) with respect to impacted soil.
Hazardous Materials Survey
As part of the hazardous materials survey, Stantec will conduct an inspection of the accessible portions of
the MBGRs and median stripe to evaluate whether suspect ACMs (MBGRs) and/or LBP (stripe) are
present in accessible materials. Representative bulk material samples will be collected from
homogeneous suspect ACM and/or LBP materials. A homogeneous area is defined as an area where the
suspect material is uniform in texture and color and appears to be identical in every respect. Stantec will
use the Asbestos Hazard Emergency Response Act (AHERA) sampling guidelines, as outlined in 40
Code of Federal Regulations (CFR) 763 to evaluate the appropriate number of ACM samples required to
be collected from each suspect homogeneous area as identified in the following table. A summary table
of AHERA guidelines is presented below.
AHERA SAMPLE CRITERIA
Type of Homogeneous Material EPA Required Number of Samples
Surfacing: Less than 1,000 square feet (sq. ft.) 3
Surfacing: 1,000 – 5,000 sq. ft. 5
Surfacing: Greater than 5,000 sq. ft. 7
Thermal System Insulation 3 samples per homogeneous material
Miscellaneous Materials Discretion of Building Inspector
In addition, if samples are safely accessible, a LBP survey will be completed using EPA and Department
of Housing and Urban Development (HUD) guidelines. Stantec’s sampling is destructive in nature and
small pieces of building materials will be collected for laboratory analysis. Stantec will not replace or
repair these materials. However, the removal of small pieces of building materials does not typically
compromise structural integrity.
Sub Task No. 1 – Pre-Field Activities & Boring Clearance
Stantec will confirm site conditions in the field and mark off the limits of the boring locations for utility
clearance through Underground Service Alert (USA).
Sub Task No. 2 – Traffic Control
In order to gain access to the painted yellow traffic median stripe along Princeton Avenue, temporary lane
closure using flaggers is required. Stantec can provide a traffic control subcontractor to temporary close
100
August 22, 2019
Page 3 of 7
Reference: LIMITED SOIL SCREENING, ACM AND LBP INVESTIGATION PROPOSAL
the lane. With Caltrans’ approval, Stantec shall perform the sampling between the hours of 9 am to 3 pm,
and lane closure shall not exceed more than 15 minutes.
The proposed soil boring locations are located no closer than six feet from the edge of pavement within
the existing Caltrans right-of-way (ROW; refer to Figure 2 in Attachment A for locations). Access to each
boring location is expected to be unrestricted.
To improve worker safety, ACM survey and soil screening work will be performed behind existing metal
guardrail barriers (where present) in such a way that the barrier will be between the field crew and traffic.
No work, parking, or walking will be permitted on the pavement during soil sampling activities and ACM
survey. Traffic control will consist of the following elements:
· Work trucks will have flashing yellow strobe lights and will be positioned as safety barriers
between workers and oncoming traffic; and
· Where appropriate, based on field conditions, W-21-5 “Shoulder Work” signs will be placed not
less than 500 feet and not more than one mile from each borehole and high visibility reflective
cones will be places along the pavement edge at least 100 feet from the work area, unless the
ample location is more than 100 feet from the oncoming traffic end of the barrier.
Sub Task No. 3 – Field Investigation
1. Field Sampling
Soil samples
Stantec proposes to advance a total of 10 borings for collection of 36 soil samples as
summarized below:
o At PIA-1 (northbound portion), Stantec proposes to advance up to four hand auger
borings as outlined in Figure 2. Three samples will be collected from each boring from the
following intervals: 0 to 0.5 foot bgs (surface), 0.5 to 1.0 feet bgs (1-foot), and 1.5 to 2.0
feet bgs (2-foot).
o At PIA-2 (southbound portion), Stantec proposes to advance up to six hand auger
borings as outlined in Figure 2. Four samples will be collected from each boring from the
following intervals: 0 to 0.5 foot bgs (surface), 0.5 to 1.0 feet bgs (1-foot), 1.5 to 2.0 feet
bgs (2-foot), and 3.5 to 4.0 feet bgs (4-foot).
It is anticipated that all borings will be advanced in areas of exposed soil. Therefore, no cores will
be necessary in pavement areas.
Soil samples will be collected directly from the hand auger bucket or using a sampling spade,
discharged to a clean zipper lock one (1) gallon bag, homogenized, then discharged to eight-
ounce laboratory certified clean glass jars. All soil sampling equipment will be decontaminated
before the collection of each sample using the three-bucket system. After removing loose or
attached soil from auger bucket, the equipment will be decontaminated using a brush in a five-
gallon bucket containing distilled water and a non-phosphate detergent. The equipment will then
be double rinsed using two additional five-gallon buckets containing distilled water. The buckets
will be placed on a clean Visqueen plastic sheet. The excess soil generated during hand augering
will be placed temporarily in 5-gallon buckets with lids (until transferred into USDOT approved
containers) and placed on clean Visqueen plastic sheet. Each sample will be labeled with the
101
August 22, 2019
Page 4 of 7
Reference: LIMITED SOIL SCREENING, ACM AND LBP INVESTIGATION PROPOSAL
borehole ID, sample depth, sample date, and sample time. All samples will be annotated on
chain-of-custody forms and delivered to Advanced Technology Laboratory (ATL) located in the
city of Signal Hill, California certified by the California Department of Health Services
Environmental Laboratory Accreditation Program (ELAP) for the analyses indicated herein. The
ELAP certification is included in this workplan as Attachment B.
ACM Shim Survey
As part of the investigation, Stantec will inspect the MBGR to determine the presence of asbestos
containing shims. If shims are identified, a total of three representative bulk samples will be
collected from the MBGR (AHERA sampling guidelines, as outlined in 40 CFR 763).
Stantec’s sampling is destructive in nature and small pieces of building materials will be collected
for laboratory analysis. Stantec will not replace or repair these materials. However, the removal of
small pieces of building materials does not typically compromise structural integrity.
Stantec assumes the following:
o Stantec will conduct all sampling from accessible locations on the shoulders; no lanes will
be closed to support ACM sampling; and
o Recommendations for suspect ACMs that are not readily accessible will be based on the
results of samples collected from similar accessible materials.
Stantec will ensure the technical quality of the survey by using State of California Division of
Occupational Safety and Health (DOSH) Certified Asbestos Consultants (CAC), and a proven
Quality Assurance/Quality Control (QA/QC) Program.
Samples will be submitted to Environmental Management Consultants Laboratory (EMC) in
Phoenix, Arizona (a State certified laboratory) for analysis. This information will be used to
identify friable and non-friable ACMs.
LBP
As part of the investigation, Stantec will inspect the yellow thermoplastic/painted traffic stripes
present along the median stripe within the PIA. Visual inspection (with a x-ray fluorescence [XRF]
analyzer) and destructive sampling for lead based paint will be completed using EPA and HUD
guidelines. Where possible, paint samples will include all paint layers which will be analyzed as a
composite. Stantec estimates that up to six LBP samples will be collected.
Stantec will ensure the technical quality of the survey by using State of California DOSH Lead
Related Construction Inspector Assessor (LRCIA), and a proven QA/QC Program.
2. GPS Data Collection
All soil sample locations (x and y coordinates) will be surveyed with a hand-held global
positioning system unit (GPS) using the NAD83 datum. The GPS data will be recorded in
accordance with the allowable format and tolerances required in the Caltrans Surveys Manual.
The GPS data for each boring will be provided in the investigation report in excel spreadsheet
format.

3. Investigation Derived Wastes
All generated soil and decontamination water will be temporarily stored in USDOT approved
containers at the Caltrans maintenance area located within the PIA and disposed at an
appropriate disposal facility based on analytical results for generated wastes. Used and soiled
personal protective equipment (PPE) will be bagged and disposed to the municipal trash.
4. Laboratory Analysis
Soil Samples
Soil samples shall be submitted to a State of California Certified Laboratory and analyzed as
follows:
o Total lead by EPA Test Method 6010 will be performed on all samples;
o Soluble lead (Soluble Threshold Limit Concentration [STLC]) using the California Waste
Extraction Test (Cal WET-citric) method using citric acid as the extractant will be
performed on all samples with concentrations of total lead that are equal to or exceed 50
mg/kg; and
o Soluble lead using Toxicity Characteristic Leaching Procedure (TCLP) by EPA Test
Method 1311 will be performed on all samples with concentrations of total lead that are
equal to or exceed 1000 mg/kg or samples with STLC concentrations which exceed 5
milligrams per liter (mg/L).
The following additional laboratory analytical testing methods will also be performed based on
field observations and a review of the initial laboratory analytical results for the purpose of
evaluating waste that will be generated during the proposed improvements:
o For waste disposal profiling, one soil sample reporting the highest total lead
concentration from each location (three total) will be analyzed for pH analysis by EPA
Method 9045D;
o For waste disposal profiling, one soil sample reporting the highest total lead
concentration from each location (three total) will be analyzed for Title 22 Metals (CAM
17) by EPA Test Method 6010B;
o For waste disposal profiling, up to two samples will be tested for total petroleum
hydrocarbons (TPH) carbon chain using EPA Method 8015M; and
o For waste disposal profiling, up to two samples will be tested for volatile organic
compounds (VOCs) analysis by EPA Test Method 8260B. To minimize the loss of VOCs,
Stantec will collect the samples to be analyzed for VOCs using EPA Method 5035/5035A.
All samples are to be analyzed on a normal 10-day turn-around-time schedule. In addition, the
laboratory limit on the analysis will be reported as Method Detection Limit (MDL) and as Practical
Quantification Limit (PQL).
ACM
Collected suspect ACM samples will be shipped under Chain-of-Custody to EMC. EMC is a
certified laboratory for bulk asbestos analysis. Asbestos samples will be analyzed using Polarized
Light Microscopy (PLM) techniques by EPA method 600/R-93/116. According to the EPA, an
ACM is defined as a material containing more than one percent asbestos. According to the
Cal/OSHA an asbestos containing building material is identified as 0.1 percent asbestos content.
The lower limit of reliable detection for asbestos using the PLM method is approximately 1

percent by volume. However, the PLM technique can identify Cal/OSHA ACMs. Although PLM
methodology cannot quantify the exact percentage of asbestos detected less than one percent, if
a sample had any quantity of asbestos, the laboratory, using PLM techniques, would identify
these materials as “trace” amounts of asbestos (< 1 percent). Only materials containing no fibers
at all are identified as “none detected”.
Stantec estimates that up to approximately three ACM samples will be collected for the project
and submitted to the laboratory for analysis.
LBP
The method of removing paint to the substrate will be followed during the collection of suspect
lead-based paint chip samples. Lead samples will be analyzed for total lead and soluble lead by
CalWET-citric. TCLP shall be performed on all samples with concentrations of total lead that are
equal or exceeding 10 times the STLC and/or 1,000 mg/kg. Stantec estimates up to two of the
LBP samples will require TCLP analysis.
Stantec estimates that approximately six LBP samples will be collected and submitted to the
laboratory for the following analysis:
o 6 LBP samples for total lead;
o 6 LBP samples for soluble lead by CalWET-citric; and
o 2 LBP samples for soluble lead by TCLP (based on the conditions).
5. Laboratory Quality Control Requirements or Quality Assurance/Quality Control (QA/QC)
The following field QA/QC samples will be collected and analyzed as part of this project:
o Equipment Blanks: One equipment (decontamination) blank per team per day will be
analyzed for Title 22 (CAM 17) metals by EPA Test Method 6010B. Equipment blanks
will be collected by passing de-ionized water over the hand auger bucket into a laboratory
supplied container for analysis.
6. Data Validation
Stantec will include a Tier 1A/1B laboratory data validation report as an attachment to the draft
and final report. The data validation shall be performed in conformance with Environmental
Protection Agency Region IX Data Validation Guidance.
7. Statistical Analysis
If the soil samples exhibit ADL levels exceeding federal or state hazardous standards, statistical
analysis may be required in accordance with the SW-846. The statistical analysis evaluation for
total and soluble lead (95 percent upper confidence limit [UCL95]) will be done for PIA-1 and PIA-
2 individually or for the project as a whole using the U.S. EPA statistical program, ProUCL,
version 5.0. The soil samples requiring statistical analysis will be discussed with Caltrans prior to
performing this analysis. If none of the soil samples show ADL levels exceeding federal or state
hazardous standards, no statistical analysis shall be performed.
Sub Task No. 4 – Meetings and Report Preparation
A. Meetings
If requested, Stantec’s project manager will meet with Caltrans project staff for two potential
conference calls: 1) A kick-off call to discuss the work plan (in office or at the project location), and
2) an investigation findings review call to discuss findings and the structure of the final report.

B. Report preparation
Upon completion of the scope of work and field activities described herein, Stantec will submit one
draft hard copy and electronic copy of the investigation report for the County review and approval
approximately 4 to 6 weeks following the receipt of all laboratory results. The limited screening
investigation will summarize the results of the field investigation, including the completed HASP,
sample location maps, laboratory analytical results, and conclusions and recommendations
specific to our findings. Stantec will address all of the County’s draft report comments and
incorporate them into the final limited screening, ACM and LBP investigation report.
The estimate of probable cost for Task Limited Soil Screening, ACM and LBP Investigation is $28,000.00.
Stantec trusts that the information obtained in this scope of work will be sufficient for approval and
implementation of the proposed investigations. Should there be any questions concerning the planned field
activities, please contact the undersigned at (805) 719-9331.
