RECOMMENDED ACTION:
Adopt Resolution No. 2012-102 approving Amendment No. 6 to extend and amend the
professional sen/ices agreement with Brown and Caldwell for the design of the Vista/Carisbad Interceptor
Sewer, Reaches 11B -15, and the Agua Hedionda Sewer Lift Station, Project Nos. 3492, 3886, and 3949.
ITEM EXPLANATION:
Proiect Background: The Vista/Carlsbad Interceptor Sewer System was constructed in 1965 and is jointly-
owned by the City of Vista and the City of Carisbad. The alignment, approximately eight miles in length
within the City of Carisbad, extends from just west of College Boulevard and Highway 78 to the Encina
Water Pollution Control Facility (Encina). There are two sewer lift stations within the alignment, the Buena
Vista Lift Station, and the Agua Hedionda Lift Station (see Exhibit 1). Both are maintained and operated by
the Encina Wastewater Authority through a joint agreement.
The upper reaches of the Vista/Carisbad Interceptor Sewer System from VCI through VC11A have been
replaced or rehabilitated in recent years. Reaches VCI IB to VCI5, which include the Agua Hedionda Lift
Station and the adjacent trestle bridge supporting the sewer across the Agua Hedionda Lagoon, are in a
state of declining condition and need to be replaced. Additionally, these facilities do not have the capacity
to convey the ultimate flows projected for the basin. The Agua Hedionda Lift Station is the City's largest
sewer lift station and is located adjacent to the lagoon on property owned by NRG Energy. The remaining
portion of the gravity sewer to Encina, approximately two miles in length, does not have adequate capacity
to meet future flows that are anticipated. Furthermore, this reach of interceptor sewer has been identified
for replacement in Carisbad's Sewer Master Plan to address the capacity deficit.
In 2008, the City selected the engineering firm of Brown and Caldwell to perform the final engineering
design of the project. In addition to the engineering sen/ices. Brown and Caldwell was asked to provide a
full sen/ice consultant team that could provide sun/ey support, geotechnical investigation, environmental
compliance documents and acquisition of resource agency permits.
Proiect Description: The project includes the replacement of the existing wood trestle bridge with a new
140-foot long steel truss bridge, construction of a new sewer lift station approximately 50-feet east of the
current facility, and construction of a new parallel force main and gravity sewer to provide increased
capacity and reliability to the sewer system. The new gravity sewer will be constructed in Avenida Encinas
and a portion of the new sewer will require installation by microtunneling. The new force main will require
construction by Horizontal Directional Drilling to avoid utilities within the area. The existing gravity sewer
downstream of the lift station was inspected in 2009 and will continue to be utilized to convey a portion of
the daily sewage flows from the new lift station and to maintain existing sewer connections south of
Cannon Road. The new sewer bridge is being designed to accommodate the occasional maintenance
vehicle and will be suitable for use by the Coastal Rail Trail as that project moves fonA/ard in the future.

Amendment Description: Amendment No. 6 to the Brown and Caldwell agreement addresses additional
engineering sen/Ices necessary to comply with CEQA requirements and to address unforeseen design
Issues. Some of the more significant Items of work being added to Brown and Caldwell's scope of work
include making revisions to the Storm Water Management Plan, revising plans to reflect ground elevation
changes as a result of Amtrak's double-track projeot, and preparing a soil and groundwater management
plan to address the requirements for handling contaminated soil during construction. Additionally,
Amendment No. 6 also extends the duration of the original agreement for an additional 3-year term to allow
for the completion of current design activities and to provide engineering design support during
construction.
The project design is approximately 90% complete and It Is anticipated that the first construction contract
for the pipeline installation in Avenida Encinas will go out for bid in the fall of 2012. The remaining two
construction contacts for the bridge and lift station will be bid in eariy 2013 once the design is complete and
the project receives all easements and discretionary permits.
ENVIRONMENTAL IMPACT:
The proposed approval of a contract amendment does not qualify as a "project" under the Califomia
Environmental Quality Act (CEQA) per State CEQA Guidelines Section 15378, as it does not result In a
direct or reasonable foreseeable indirect physical change in the environment.
A Mitigated Negative Declaration (MND) and Mitigation Monitoring and Reporting Program (MMRP) were
prepared for the Agua Hedionda Sewer Lift Station, Force Main and Gravity Sewer Replacement project
(PDP 00-02(C)/SP 144(L)/RP 10-26/CDP 10-17/HDP 10-05/SUP 10-02/HMP 10-03) and were adopted by
the City Council at meeting held on December 6, 2011.
FISCAL IMPACT:
The fee for the additional sen/ices included in this Amendment is $81,718, which includes a $20,000
contingency amount. Subsequently, it is anticipated that another amendment with Brown and Caldwell will be
required prior to the start of construction to provide engineering support sen/ices during construction. These
sen/ices will be negotiated at a future date. A summary of current and projected project costs is as follows:
PROJECT COST SUMMARY FOR THE AGUA HEDIONDA SEWER LIFT STATION AND V/C
INTERCEPTOR SEWER REPLACEMENT PROJECT, REACHES VCI IB - VCI5
(PROJECT NOS. 3492, 3886, AND 3949)
Manhole Rehabilitation Contract (Completed - Actual Costs) $344,900
Studies, Environmental Compliance and Design Activities (As of 3/31/2012) $3,549,121
Existing Encumbrances $433,993
Proposed Amendment No. 6 to Brown and Caldwell Agreement $81,718
City Project Management and Miscellaneous Costs (Estimated) $50,000
Subtotal of Costs (Through Design) $4,459,732
Utility Relocation, Easement Acquisition and Railroad Fees $1,380,000
Estimated Construction Phase Costs & Contingency $40,261,000
TOTAL ESTIMATED PROJECT COST $46,100,732
TOTAL APPROPRIATIONS TO DATE $46,230,000
ADDITIONAL APPROPRIATION REQUIRED $0
Sufficient funds are currently available for the completion of the project. All project related costs will be
shared between the City of Carisbad and the City of Vista as described within the existing 2002 ownership
agreement between the two cities for operation and maintenance of the Vista/Carlsbad Interceptor Sewer
System.
Pages
A project specific agreement has been prepared with Vista to define the administrative procedures and
payment schedule for expenses incurred during the planning and design phase of the project. Vista has
paid Carisbad for their share of these expenses incurred to date. A second project agreement with Vista
will be prepared prior to bidding the project to address noticing requirements and billing procedures during
construction. The total project cost share between the two cities is approximately 65-percent Vista and 35-
percent Carisbad; however, the actual cost share varies with each reach ofthe sewer. Carisbad's share of
the project is funded from the Sewer Connection Fee Fund. The City of Vista will be using State Revolving
Funds to pay for their portion ofthe project.

Agua Hedionda Lift Station and
V/C Sewer interceptor Repiacement
Projects - City of Carisbad
Proposal for Additional Engineering Support and
Final Design Services - Updated March istt'2012
Background
The City of Carisbad engaged Brown and Caldweii in June 2008 to prepare three (3) separate
bid packages for construction of the Agua Hedionda Lift Station (AHLS) and V/C Interceptor
Sewer project facilities as follows:
• Package 1 - Agua Hedionda Sewer Lift Station and Forcemain Project
• Package 2 - V/C Interceptor Sewer and Lagoon Bridge Replacement Project
• Package 3 - V/C Interceptor Relief Sewer and Recycled Water Pipeline in Avenida Encinas.
Currently Packages 1, 2 and 3 are atthe approximate 90 percent design completion level and
project construction is scheduled to begin in 2013. The construction efforts will occur in parallel
with some overlap, and will be completed in the following series:
• Package 3 - V/C Interceptor Relief Sewer and Recycled Water Pipeline in Avenida Encinas.
• Package 2 - V/C Interceptor Sewer and Lagoon Bridge Replacement Project
. Package 1 - Agua Hedionda Sewer Lift Station and Forcemain Project
Amendment - 006 Proposal for Additional
Engineering Support and Final Design Services
Recently, and during project final design, certain changing site conditions have resulted due to
nearby construction completed by others, agency requirements, additional design work,
additional engineering support and coordination work, and design changes requested bythe
City. As a result, these changes necessitate additional engineering services outside the
contracted scope of work. This proposal requests additional compensation for work as
described in the phases outlined below.
The work described below will be added to the existing project contract by Amendment 006 and
is proposed to be completed for the costs shown on the attached detailed fee breakdown.
Schedule for Work:
Note: The work of Amendment 006 is planned to be completed by the fall of FY 2012. However
EC's current contract is set to expire prior to the end of the year and completion of project final
design including the Amendment 006 work items prior to this. BC's project engineer Nicholas
Boswell next requested thatthe City provide a 1 year extension to the contract.
At that time City of Carlsbad PM Terry Smith (on 2-16-2012) advised that the City is aware of
the issue and is working with the City Attorney's office to obtain a needed 1 year extension to
complete the work.
Brown AND Caldwell jl
Amendment 006 - Additional Engineering Support and Final Design Services
Amendment Scope Elements by Work Phase
The proposed additional scopes of work (Phases 20 through 25) include descriptions for detailing which of the three project
construction bid packages (Bridge, Lift Station and Gravity Sewer) will be updated by the work, and expected engineering,
CAD, and subconsultant work needed for their completion.
Phase 020 - Update to Storm Water Management Pian
Bid Package(s) Impacted: • All packages.
Phase CAD and Engineering Effort: • Work includes update to project SWMP prepared for construction of the AHLS
facility to be submitted as attachment to each final Bid Packages 1-3.
Under Phase 020, Brown and Caldwell will update the project Storm Water Management Plan (SWMP) prepared previously
for construction of the AHLS project facilities to justify project hydromodification exemption. The work includes generation of
one updated CAD figure showing that the project directly discharges storm water runoff to Agua Hedionda Lagoon, which is
exempt from hydromodificafion criteria. Mean tide levels and lOO-year floodplain information forthe lagoon will be obtained
and compared to the Agua Hedionda Lift Station site outfall elevation. Addifionally, the energy dissipation system at the
conveyance system outfall will be reviewed and to ensure that the post construction local scour from the combined project
discharge is mitigated as required bythe project discharge requirements established bythe regional board. If found out of
compliance. Brown and Caldwell will notify the City immediately ofthe issue and, if requested, provide proposal for detailed
design to modify and correct the discharge outlet condifion.
Phase Assumption: Estimate includes time for coordinafion phone calls with the City of Carlsbad staff and one City meeting.
Phase Deliverables:
1. Draft language and figure needed to update SWMP; one electronic copy as PDF and nafive file formats.
2. Final updated SWMP; one electronic copy as PDF and native file formats, plus two updated hard copies of
Final SWMP.
Phase 021 - Add to Project Design Work to Locate and Rehabilitate IVIanhole
Bid Package(s) Impacted: • Bid Package 3
Engineering Effort: • Prepare one plan view blow up detail and notes to direct the work.
• Prepare one section detail and notes for the work.
• Prepare one specification section to direct the Contractor how to
complete the work and incorporate one City-provided specification for
manhole rehabilitation.
• Coordination w/ City, CAD and cost estimator to add work.
CAD Effort: • Prepare one plan view blow up detail and notes to direct the work.
• Prepare one section detail and notes for the work.
Cost Estimation: • Add to Bid Package 3 cost estimate the new construction work of Phase 021.
The City previously completed a manhole rehabilitation contract for all manholes located on sewer reaches VCllB - VC15
that repaired manholes found to be in poor condition. At that time all manholes were addressed, with the exception of one
located near the intersection of Avenida Encinas Road and Palomar Airport Road that was not able to be physically located
from above grade. It is believed that the manhole rim and access shaft were buried by construction of the Palomar Airport
Road Bridge Crossing project with the rim underneath the bridge embankment fill and not raised to grade. The City has
internal closed-circuit television (CCTV) inspection data which confirms the manhole's existence. The manhole is located in
close proximity to existing buried high pressure gas pipeline and other utilities.
Under Phase 021, Brown and Caldwell will add to the Package 3 design the work for the Contractor to locate and repair this
manhole. Upon commencement ofthe Phase 021 design work. Brown and Caldwell will discuss with the City and confirm
the preferred replacement method to be used for the project and incorporated into the Package 3 bid documents.
The manhole will be repaired by either:
• Rehabilitating the manhole interior per City specification, capping the manhole in place, removing the remaining exisfing
risers, then backfilling to restore exisfing conditions; or
• Rehabilitafing the manhole interior per City specification and installing new manhole risers to grade for future access,
risers, and then backfilling to restore exisfing condifions.

Amendment 006 - Additional Engineering Support and Final Design Services
Following City direcfion. Brown and Caldwell will update the contract documents and cost esfimate. Brown and Caldwell will
prepare and incorporate to the drawings one plan detail figure and one manhole excavation section figure with notes to
direct the work. Brown and Caldwell will prepare one new specificafion secfion to for the addifional work and will
incorporate one City-provided specification section for manhole rehabilitafion. The work is located within an exisfing City of
Carlsbad sewer easement but is also in close proximity to the vehicle overpass at Palomar Airport Road for the railroad. If
right-of-way permits are required for the work. Brown and Caldwell will include requirements for the Contractor to prepare
the permit applications and acquire permits. No permit acquisition work is included by Brown and Caldwell. Brown and
Caldwell will update the Project 3,90 percent and Final engineer's cost esfimate to include the work of Phase 021 to field
locate and rehabilitate the sewer manhole.
Phase Assumptions:
• No field or aerial survey work is included in Phase 021 by Brown and Caldwell. Contractor to field locate manhole prior
to construction. Design will be based on record information provided by the City.
• City to provide CCTV data inspection reports and manhole rehabilitafion specificafion from previous manhole
rehabilitafion project.
Phase Deliverables:
3. Final Package 3 contract documents to include manhole locafion and rehabilitafion work.

Following completion ofthe project aerial mapping, field survey and base drawing development efforts, and at the
approximate 90 percent design level, Amtrak began construction of its "Double Track Expansion Project" which installed a
new second rail line east of the current track and adjacent to the project area. Attached to this proposal is an aerial photo
from project survey subconsultant SDE that shows the approximate limits of Amtrak's work which impacts the AHLS project.
The improvements include construction ofa new rail line, drainage improvements, retaining walls, bridge crossing for the
Agua Hedionda Lagoon, and mass earthwork north and south ofthe lagoon crossing. These changes impact the survey and
design work completed previously for project Bid Package 1 and Bid Package 2. Additionally, based on the flnal grades in
the area of the lagoon crossing the existing structural design of Package 2 will be updated to lower the flll near the bridge
deck by 2-feet to reduce the project cost. The work to update the bridge and retaining walls will be completed by
subconsultant R2H Engineering with coordination by BC.
The Phase 022 work includes all effort needed to update Bid Package 2 and Bid Package 1 for Amtrak's fleld changes
including engineering, CAD, project management and QA/QC. Initially work will be completed by SDE to generate new
electronic aerial survey the Amtrak grading changes that impact the job in order to update the project topographic base
mapping. The work by SDE is not part of Amendment 6 and will be coordinated through the City.
Through Amendment 6, Brown and Caldwell will use the updated topographic data provided by SDE to update the grading
and redesign the proposed grading, drainage systems, and other design elements for all plans of Package 2 and Package 1.
Brown and Caldwell will also coordinate with R2H to modify the structural bridge design documents to reduce the project
impact by lowering the flll at the lagoon crossing by 2-feet and shorten the associated retaining walls as well as incorporate
the changes to our plans.
See attached R2H proposal for structural design update.
Phase Assumptions:
• SDE to provide updated topographic grading flie in CAD format showing Amtrak's flnal grading.
• Project subconsultant R2H to update the structural design package, per the attached proposal.
Phase Deliverable: Modify Package 1 and Package 2 Contract Documents to account for changed condifions resulting from
the Amtrak expansion project.

deliverables for Phase 024 work.
Background: To construct the AHLS project facilities, large amounts of earthwork is needed and large volumes of existing
soil must be disposed of offsite by the Contractor. During project preliminary design, soil and groundwater samples were
collected from the AHLS site area and tested environmentally to asses any associated impacts needed for project
construction earthwork, dewatering, and safety. The investigation results are presented in the project Environmental Soil
and Groundwater Sampling Report developed by Ninyo & Moore. The report flndings indicate that soil and groundwater

Amendment 006 - Additional Engineering Support and Final Design Services
removed from the AHLS site during construction grading and dewatering may contain contaminants above screening levels
or permitted concentrations. Therefore, the soil and groundwater that is encountered during construction may require
special treatment prior to disposal by the Contractor in accordance with applicable regulations for proper disposal. The
report concludes that a subsequent project speciflc construction soil, safety and groundwater management plan be
developed to limit construction risk and lower construction cost.
Phase Deliverables:
8. Draft construction SGMP; one hard copy and CD with one electronic copy as PDF.
9. Final construction SGMP; two hard copies and CD with one electronic copy as PDF and one electronic copy as MS
Word flle(s); updated drawings and speciflcations to address SGMP and CHSP recommendations.

AGUA HEDIONDA LAGOON LIFT STATION AND FORCE MAIN
SOIL MANAGEMENT AND DEWATERING PLAN SCOPE OF WORK
Project Understanding
The Aqua Hedionda Lift Station project involves construction of a new 33-mgd sewer lift
station, 1.5 miles of 54-inch gravity sewer, and 4,000 feet (HDD construction) of 36-inch
force main needed to upgrade the existing lift station and conveyance system. As part of the
preliminary design assessment for the project, several soil samples were collected from
geotechnical soil borings for environmental testing. Attached to this scope of work are
figures that show the locations of the borings completed for the project. In addition,
samples were collected from shallow groundwater to determine potential impacts from
groundwater on dewatering options. Results from this sampling were presented in the
Enmronmental Soil and Groundwater Sampling "Repori developed by Ninyo & Moore.^ The
following findings were found from the investigation:
• Boring B-6 located within the footprint of the proposed lift station showed non-
detect or low concentrations for aU of the analytes with the exception of organo-
chlorine pesticides (endosulfan I, endosulfan II and 4,4-
dichlorodiphenyltrichloroethene [DDT]), with DDT concentrations detected above
the United States Environmental Protection Agency (U.S. EPA) regional screening
levels for both residential and industrial land uses.
• Total petroleum hydrocarbons (TPH) were detected in samples B-7 and B-20 at
depths of 36 and 5 feet below the ground surface (bgs), respectively.
• Groundwater samples collected from B-14 and B-18 had detections of TPH, and B-
18 had detections of volatile organic compounds (VOCs).
Soil and groundwater removed during grading and dewatering could contain contaminants
above screening levels or permitted concentrations. Thus soil and groundwater may need to
be properly re-used or removed for proper disposal disposed in accordance with applicable
regulations. To allow for management of the potentially impacted soil and groundwater,
Brown and Caldwell will develop a Soil and Groundwater Management Plan (SGMP) and
associated community health and safety plan (CHSP). The following scope of work (SOW)
presents the detail of the SGMP.
Soil and Groundwater Management Plan
The SGMP wiU be developed to aUow for the proper assessment and disposal of soil and
groundwater, as to be in accordance with applicable laws and regulations, and to help
prevent costiy downtime during grading or pipeline installation. The SGMP will follow and
address the project CEQA mitigation requirements identified for the project. The three
components of the plan, CHSP, soil management plan and groundwater management plan,
are described further in the following sections of this scope of work.
It should be noted that it may be appropriate to get regulatory approval of this plan, such as
through a Voluntary Assistance Program (VAP) case through the San Diego County
Department of Environmental Health, especially in the event that removal of significantiy
1 Ninyo & Moore, 2009. Environmental Soil and Groundwater Sampling, Agua Hedionda Lift Station and
Force Main, Carlsbad, Califomia. August.
impacted soil occurs prior to the grading.
Community Health and Safety Plan
During removal of impacted soil a CHSP will be required. The CHSP will be prepared in
accordance with Section 4, IV of the San Diego County Department of Environmental
Health Site Assessment and Mitigation (SAM) Manual. The plan will include a site
description and maps, hazard analysis, potential monitoring equipment, control measures,
emergency planning, and a public notification program. It should be noted that a Site
Specific Health and Safety Plan (SSHP) wiE not be developed as part of this scope of work.
A SSHP should be developed by the contractor who is performing the work, so that it meets
their specific company requirements and be representative of potential project personnel.
The requirement of the SSHP will be presented in the final SGMP and should be relayed to
fiature contractors.
Soil Management
The soil management plan will be based on the assumption that the locations planned for
soil reuse or disposal will be identified by the Contractor and agreed to by the Owner prior
to excavation. The soil management plan will focus on three areas:
• Further assessment of impacts (i.e. additional soil borings and analytical testing);
• Details and regulations for removal of soil and confirmation sampling if testing
indicates that "hot spots" are present that need to go to a landfill; and
• A discussion of disposal options for remaining soil (if "hot spot" excavation is
performed). These options will be presented, but will ultimately have to be based on
the results of the additional testing;
The disposal options that include potential soil re-use will include identification of associated
laws and regulations, and have a general summary of associated requirements. The
regulations are stringent and based on use of the soil in areas of industrial use or beneath
roads or other non-residential features, so a suitable location for the placement of this soil
will be identified and presented in the SGMP.
Groundwater Management
The SGMP will be prepared in accordance with the County of San Diego Department of
Environmental Health's Site Assessment and Mitigation Manual, RWQCB guidelines, and
the standard of care of the industry. For uncontaminated groundwater encountered during
construction dewatering, groundwater will be tested and discharged to the local sewer system
for treatment per Encina's existing NPDES permit requirements. To address disposal
options for potentially contaminated groundwater, the SGMP will identify the governing
regulations, testing requirements and disposal options based on the results of additional
testing to be completed by the Contractor and needed for disposal of contaminated
groundwater encountered during construction dewatering.
Results of the preliminary groundwater sampling completed by Ninyo and Moore indicate
potential containments in the soil and/or groundwater observed at the following project
