that naturally occurring gas collected continues to vent
through City passive venting system.
0 0 0
Conclusion
• The City is not responsible for naturally occurring gas surfacing on
private property.
*Recent data from BAS does not support speculation that naturally
occurring gas is seeping through the existing sewer main trench,
moving laterally underneath the street pavement, and then onto the
home owner's yard.
*Existing Passive Venting System is effectively serving its purpose.
0 0 0
Summary
• Over the last twelve (12) years, actions taken by the City
have significantly reduced the impact of naturally occurring
gas in this area by Christine Drive and Susan Lane.
• Beside the recommended mitigation actions, there is
nothing else the City can do to address this naturally
occurring gas issue.

Subject: Repairs to Subsurface Gas Mitigation System in the vicinity of
Christine Drive, Huntington Beach, California
Dear Mr. Scott:
As per your request, a meeting was held with City of Huntington Beach officials
on November 20, 1999 to review information on the existing subsurface gas
mitigation system at the subject site. Additional field explorations were made
along Christine Drive and the results were discussed with Fire Department
officials, as well as previous high levels of methane gas and hydrogen sulfide
readings in this area (see attached table).
1 had obtained a copy of the storm drain drawings from the City of Huntington
Beach last year. It appears that the drain pipes under Christine Drive, Hula
Circle and Susan Drive extend below the upper clay layer into the silty sand
materials, with much higher permeability. It seems likely that gases are rising up
under the asphalt streets, then spreading laterally to yards and adjacent
properties.
The previously installed gravel trenches with gas collection pipes were placed
along the sidewalks, approximately 10 feet from the street curbs, in the upper
clay soils. Thus, these trenches and pipes do not properly intercept the methane
gas under the roadway and have not significantly decreased the gas levels in
this area,
In order to install a more effective gas mitigation system, the following action
items should be done by SEHBNA personnel and City of Huntington Beach
officials and consultants.

`<<°
SERVICES IN SUPPORT OF THE CHRISTINE DRIVE -ME
GAS ANOMALY PROJECT
Statement of Issue, Funding Source, Recommended Action, Alternative Actlon(s), Analysis, Environmental &tun ttachment(s) I .-t-s"
Statement of Issue: Should the City fund environmental engineering services in support of
the Christine Drive Methane Gas Anomaly Project?
Funding Source: An appropriation of $100,000 from the Undesignated, Unappropriated
Fund Balance of the General Fund to the Fire Department Fire Prevention Professional
Services account (10065201.69365) is recommended to fund environmental services in
support of the Christine Drive Methane Gas Anomaly Project. The Fiscal Impact Statement
is attached (Attachment 1).
Recommended Action: MOTION TO:
1) Approve and authorize the appropriation of $100,000 from the Undesignated,
Unappropriated Fund Balance of the General Fund and transfer to the Fire Department's
FY 2000/01 Fire Prevention Professional Services account (10065201.69365); and
2) Approve and authorize the Mayor and City Clerk to execute the Proposal and
Professional Services Agreement for Environmental Engineering Services for Christine
Drive Gas Anomaly Project Between Brown and Caldwell, Environmental Consultants,
and the City of Huntington Beach, in the amount of $46,830.
3) Approve waiver of Section 8 Standard Indemnification clause as recommended by the
Settlement Committee.
Alternative Action(s): Do not approve the request. Without supplemental funding,
environmental engineering support services will not be available and the Christine Drive
methane mitigation plan will not be completed.

*QUEST FOR COUNCIL AC*N
MEETING DATE: May 21, 2001 DEPARTMENT ID NUMBER: FD 01-008
Analysis: Currently, the mitigation measures on Christine Drive, implemented by City
consultants between 1991-1994, appear to be ineffective since sulfide odors have returned to
the area resulting in negative impacts to neighborhood lawns and other area vegetation.
Additionally, further analysis is required to determine if gases in the area are a health and
safety issue, or only a nuisance.
At this time, City staff is recommending that Brown and Caldwell, Environmental Consultants,
be used for the following tasks in the Christine Drive Methane Gas Anomaly Project:
Part 1: Compile existing historical data for the site into a Geographical Information System
as described in their proposal dated December 20, 2000 (Attachment 2).
Part 2: This part is detailed in the Brown and Caldwell Proposal and Letter Agreement for
Environmental Engineering Services Christine Drive Gas Anomaly Project (Attachment 3)
and includes the following tasks:
• Review and evaluate the distribution of gases and site characteristics through aerial
photographs.
• Define specific parameters to identify the source of methane gas.
• Identify the data gaps between interpretations presented by the City, County and local
neighborhood association.
• Provide as -needed consulting in developing future plans and identifying engineering
controls necessary for ongoing site mitigation measures.
• Provide assistance in managing additional field investigations and mitigation.
• Provide as -needed consulting to the City's Project Manager for communicating project
status and findings with the Huntington Beach local community.
The technical expertise of Brown and Caldwell, professional Environmental Consultants, is
necessary to adequately analyze, evaluate, and address the potential health and safety
issues associated with the Christine Drive Methane Gas Mitigation Project. The services
provided in the proposed agreement are necessary to accurately understand site conditions
and provide the short and long term gas mitigation measures. The proposal from Brown and
Caldwell for these services is for $46,830. In the event that existing data are not sufficient to
provide conclusive answers to all of the outstanding issues related to the Project, including
the orgin of the methane, factors controlling its distribution, and effective engineering
controls, additional funding may be required, up to the balance of the $100,000 appropriation
requested of City Council.
To comply with Chapter 3.03 of the Huntington Beach Municipal Code, the Fire Department
requested, received and evaluated formal written proposals from three qualified consultants.
Based on the needs of the project, Brown and Caldwell, Environmental Consultants, is
recommended.
The Professional Environmental Services Agreement (Attachment 4) has been reviewed and
approved as to form by the City Attorney.

%QUEST FOR COUNCIL ACAN
MEETING DATE: May 21, 2001
DEPARTMENT ID NUMBER: FD 01-008
Modified Indemnification and Insurance Requirements: Paragraph 8 (A) — (C) of the
Brown and Caldwell Professional Services Agreement includes limitations of indemnification
obligations of the consultant to the City. Specifically, Brown and Caldwell made these three
(3) requests:
1. Limit the indemnification obligations to acts of negligence only.
2. Limit indemnification damages to the value of the contract.
3. Require the City to indemnify the vendor in the event of damage attributable
to preexisting pollution conditions.
The indemnification limitation is in conflict with the standard indemnification provision
required by Resolution 97-20 which requires full indemnification from the vendor to the City
for any and all claims, including attorney's fees.
In their meeting of April 10, 2001 (Attachment 5), the Settlement Committee reviewed,
evaluated, and voted to recommend the modifications to the City's standard indemnification
language and approved, in concept, Brown and Caldwell's limitations of liability.
New Appropriation Criteria: In March 1998, the City Council adopted three criteria to follow
in requesting a new appropriation. The three criteria include: 1) unanticipated emergency 2)
requirement to implement labor negotiations 3) new expense that is offset by related new
revenues. This request falls under Criteria 1, it is an unanticipated emergency. The
Christine Drive methane gas problem is a potential City liability and may pose a health and
safety issue to the neighborhood. Without the professional services environmental
engineering contract, the City will not be able to accurately evaluate the neighborhood gas
problem nor provide the needed gas engineering controls.
Environmental Status: None.

Subject: Proposal and Letter Agreement to Compile Existing Christine Drive
Site Data into a Geographical Information System (GIS)
Dear Chief Dolder:
In accordance with your November 28, 2000, request Brown and Caldwell is pleased to
present this letter proposal to compile existing historic data for the Christine Drive Site
(Site) into a Geographical Information System (GIS). As we discussed during the
November 28" meeting, this proposal is the first task (Task 1) in a series of tasks in
support of the Christine Drive Gas Anomaly Project. The remaining tasks are included
in a separate proposal.
OBJECTIVE
The Christine Drive Site, located in the City of Huntington Beach (City), has experienced
historic problems with methane, hydrogen sulfide and other trace gas seepage from the
subsurface. The objective of this Scope of Work is to create a central electronic
repository of current and historical Site information to be used for Site documentation
and as an analytical tool. The organization of project data will minimize the review time
of City contractors and City employees as the project progresses. It also will provide a
historical record of this site for a variety of future uses.
SCOPE OF WORK
Based on the information provided to Brown and Caldwell by the City of Huntington
Beach Fire Department in early November, gas emissions have been an issue at the Site
for some time and a passive venting system has been emplaced to control and monitor
the emissions. Over time, a significant amount of chemical, geological, and
hydrogeological data have been collected by various consultants and City employees. The
data collected to date are difficult to use in their current state because they reside in a
• number of unrelated paper documents with no correlation between data sets, and are not

keyed to a unified basemap. Compilation of these data in one electronic repository along
with Site specific electronic maps including city infrastructures, utilities, sample locations
and results, control measures, etc. can be used to further evaluate the data in a variety of
scenarios. This will help achieve a better understanding of existing Site conditions and
identification of data gaps, and ultimately facilitate development of permanent mitigation
recommendations.
In order to achieve the objectives associated with Task 1, Brown and Caldwell will
implement the following subtasks:
■ Subtask 1.1 -Review existing project Site files and information.
■ Subtask 1.2 - Design and develop a Site -specific GIS Model.
■ Subtask 1.3 - Populate and QC the Site -specific GIS Model.
■ Subtask 1.4 - Create a Site -specific historical action Record Table.
Details and assumptions associated with these subtasks are described below.
Subtask 1.1- Review Existing Project Files
• Brown and Caldwell will review the project files provided by the City to identify the
types and quantity of the information available. Source documents will be identified and
organized for inclusion to the GIS. Data included in the GIS will reference these source
documents.
Subtask 1.2 - Develop a Site -Specific GIS Model
Using the information obtained in Subtask 1.1 and the ultimate objectives for the use of
a GIS, Brown and Caldwell will develop a Site -specific GIS data Model. The model will
be designed to store available information that may include:
■ Utility corridors, piping layouts, etc.
■ . Surface elevation data.
■ Coordinates and locations of sample points, wells, etc.
■ Chemical concentrations in soil gas, soil, groundwater.
■ Existing locations / layout of control measures.
Additional relevant information found during the document review may also be
included. The amount and type of information included in the GIS will depend on the
type and format of data provided by the City of Huntington Beach.

Subtask 1.3 ,- Populate and QC the GIS Model
After the project files have been reduced to raw data, they will be digitized into the GIS.
The accuracy of the digitized data will depend on the accuracy of the source documents.
Color plots will be produced and forwarded to the City for review and comment. One
meeting with the City has been included in the project budget to discuss and resolve data
quality and display issues.
Subtask 1.4 — Create an Action Record Table
In order to complete Subtasks 1.1 through 1.3, it is necessary for Brown and Caldwell to
read the majority of the provided project documents. With this level of effort already in
progress, BC will create an action record table or database that summarizes efforts made
by the City to mitigate the adverse Site conditions with little additional effort. This
information may be useful to show diligence on the part of the City in the future.
ASSUMPTIONS / EXCLUSIONS
It is assumed that the following items will be provided to Brown and Caldwell by the
. City of Huntington Beach, in digital format, on a common base coordinate system, prior
to the commencement of work:
1. A parcel base map of the Site in ArcVIEW shape file or ArcINFO coverage
format.
2. Utility maps of the Site showing the manholes and centerlines of all sewer,
storm drain and water lines in shape file or coverage format. If available, the
invert elevations of these lines should also be provided.
Any other pertinent site information should be forwarded to Brown and Caldwell for
review and potential inclusion in the GIS prior to the commencement of work.
We understand that for Brown and Caldwell to use the City's digital Landbase/GIS
Mapping data as the base for the project data, the City requires certain agreements be
signed by Brown and Caldwell. We have received the following documents from
Mr. Douglas Stack from the City of Huntington Beach Department of Public Works:
• Digital Landbase/GIS Mapping Non -Disclosure Statement
• City of Huntington Beach Digital Data Loan Agreement Statement
• City of Huntington Beach Addendum to County of Orange Non -Disclosure
Statement
• These documents are currently under review by our corporate legal department.

Analysis of the data is specifically excluded from this scope of work but will be included
in Tasks 2 through 4 proposed under separate cover (see above). The quantity and
accuracy of data included in the GIS will depend on the quality and accuracy of the
source data provided by the City.
DELIVERABLES
Following the completion of this scope of work, Brown and Caldwell will deliver to the
City of Huntington Beach two (2) copies of an ArcVIEW, (or ArcINFO) project file and
the associated shape theme files (or coverages), described above, on compact disc media.
Brown and Caldwell will also submit up to four (4) large format color plots as necessary
to summarize the data and a transmittal document that describes the contents of the GIS
and the associated meta data.
PROJECT ORGANIZATION
Schedule
Should the City of Huntington Beach require Brown and Caldwell to begin work
. immediately, you may accept this proposal and authorize Brown and Caldwell to begin
by signing and dating two (2) copies and returning one (1) copy to Brown and Caldwell.
It is anticipated that this scope of work will be completed within four (4) weeks of
authorization to proceed.

Subject: Revised Proposal for
Envirou mental Engineering Services
Christine Drive Gas Anomaly Project
Deax Chief Dolder:
In accordance with out recent discussions and in order to be responsive to verbal requests
made by Jennifer McGrath of the Ciry's Attorney's Office on April l0, 2001, Brown and
Caldwell is pleased to present this revised letter proposal to provide environmental
engineering services in support of the Christine Drive Gas Anomaly Project. Should the
City fmd this proposal acceptable, we understand that a new contract will be executed
between Brawn and Caldwell and the City of Huntington Beach that incorporates both the
substance of this technical proposal as well as appropriate contractual terns and conditions
including the modifications set forth below,
OBPECTIvE
The Christine Drive Site, located in the City of Huntington Beach, has experienced historic
problems with methane, hydrogen sulfide and other trace gas seepage from the subsurface.
The objectives for this sct-pe of work ate to:
• Develop an understanding of the site characteristics, with a focus on those
characteristics controlling the distribution of the gases,
• Identify data gaps than: need to be filled to further develop this understanding,
• Provide assistance to the City in the evaluation of plans for future studies and/or
engineering controls to augment the ongoing mitigation measures,
• Provide as -needed assistance during the City's implementation of further field
investigations and mitigation, and
• provide as -needed consultation to the City's Project Manager for communicating
project status and findings with the local community (Southeast Homeowners
Association).
Under a separate contract with the City, Brown and Caldwell has assembled the existing
project data developed thins far by other consultants and by City personnel into a Graphical
Information System (GIS) model. As you know, Brown and Caldwell has not performed
any interpretation of these historical data at this time.

Further explanation of the: components of this scope of work is provided in more detail
below.
Scon of WORK
Task 1. Review Aerial Phonographs
Objective:
■ DocxmewHirtostcal U'se/Can& on ofthe Chntthw DrimAr%;-
The residential development in the vicinity of Christine Drive was reportedly constructed in
the early 1960s. In previous assessments performed by others, it has been assumed that the
development was constmeted over marshland. In order to document the prior condition of
the area and perhaps gain insight for understanding the tnethane occurrence, Brown and
Caldwell will review historical aerial photographs of the site with a focus on photographs
oaken prior to sire development. In order to obtain a comprehensive net of photographs,
several sources of aerial photographs will be reviewed such as the Fairchild collection at
Whittier College, Rupp Aerial Photography, and UCLA.
The photographs will be Examined to document features relevant to the area such as
historical drainage courses, indications of industrial activity or other features that may
contribute to the understanding of the source or distribution of the methane accumulations.
A log of observations of each photograph will be compiled Copies of relevant
photographs will be purchased to become part of the project file.
A brief letter report prepared as part of Task h will document the overall findings of this
review, and will include the observation log and copies of all relevant photographs.
Task 2. Hydrogeologic Review
obectives:
■ Detxlop a hydrogeologic model of the area.
■ Understand the relahonship between the hydrngeologp and the tnetliane ocewwnce.
Brown and Caldwell will review the accumulated hydrogeologic data and methane
occurrences to independently dewelop a hydrogeologic model of the subject area. The
model will incorporate the existing data developed by Keith Tucker for the Southeast
Homeowner's Association, Geoscience Analytical's site investigation results, and other
records provided by the City in regards to this site. The goal is to utilize all of the existing
data to develop as accurate an understanding as reasonably feasible of the shallow
subsurface and to evaluate the control that strata may have on the distribution of the gases
in the Christine Drive are:. For example, gas migration along the base of the clay might be
expected. Therefore, mapping the elevation of the base of the clay mighr provide insight m
migration pathways and accumulation points. It is assumed that prior to this review, the
data will have been digitized and entered into the GIS system.

Brown and Caldwell will also include in this review an analysis of the data in regards to the
theory that the groundwaier levels rose in the area due to the installation of the sheet piling
along Talbert and Huntington Reach Channels. Rased on our review of the hydrogeologic
data described above, we will provide critical review of the Bing Yeti & Associates (BYA)
March 1996 study regarding this issue (Talbert and Huntington Beach Channel
Hydtogeologic Study).
Deliverables relative, to this task, including identification of data gaps which must be &lied
for a reasoned analysis, are included in Task 4.

Subsequent to the hydrogeologic evaluation, the relationship of the subsurface utility
lines/trenches to the methane occurrences and hydrogeology will be examined. The
interpretations presented by Keith Tucker for the Southeast Homeowner's Association and
Geoscience Analytical in regards to the relationship between City utilities and the methane
occurrence will be reviewed. Their presentations of the data will be compared to City -
provided engineering drawings and the City -provided hydrogeologic data to check that their
presentations accurately reflect the data and site conditions and for verification that the data
support their interpretations.
A part of this hydrogeologic and engineering evaluation will be to develop potential
scenarios for the source of the methane and criteria by which these scenarios may be
differentiated. An undetsianding of the ultimate source of the methane may help refine
further mitigation and planning efforts. The most likely sources mentioned to date include
degradation of natural or€;anic material entrained in sediments associated within an or$aruc-
rich depositional environment upon which the development was built, a sewer leak, or gas
migration from natural petroleum deposits. The existing site darn will be analyzed in light
of these criteria, ro see if -a supportable interpretation can be made as to the
possible/probable source of the methane.
The design of the existing, ps mitigation control structures will also be subjected to a
preliminary review at this time. Based on our very limited knowledge of the Site, Brown
and Caldwell may be able to provide simple conceptual recommendations regarding
possible future enhancements of the gas control/mitigation system.
Deliverables relative to this task, including identification of data gaps which must be filled
for a reasoned analysis, are included in Task 4.

and 3.
■ Ident:.6 Data Gaps mwded to coufidenty xnderatand am and gas oa nvncer and plan
future :cork.
Brawn and Caldwell will provide a written report oud ning the results of the aerial photo
review, hydrogeology and engineering reviews, and resulting analysis that was completed
under Task 1 through 3. The report will outline key findings of Brown and Caldwell's
independent review, and major areas of agreement or disagreement with interpretations
presented by Keith Tucker, Geoscience Analytical, and Bing Yen and Associates. It is
anticipated that in addition to a narrative description of the data reviewed and the
conclusions reached, the report will include cross sections, several GIS maps, and possibly
additional drawings to illustrate the site conditions based on the existing data. The
underlying goal of further analysis at this time is to reach an understanding of the site
conditions (the natural en%*orunrnt and currently installed engineering systems and
structures) in order to plan future mitigation. It is probable that the existing data are not
sufficient to provide conclusive answers to all of the outstanding questions such as the
origin of the methane, factors controlling its distribution, and effective engineering controls
or other means of mitigating the gas accumulation and migration. Therefore, this report
will include identification of data gaps to be filled in order to better understand and plan
future efforts, along with i-ecommendations of further work to gather the dara,.
Task 5. Provide As -Needed Consulting in Evaluation of Future Site Work
Objective:
■ Evaluate ff planwd work tear help achieve the stated objective.
■ Pmvide reconwwndasion r 6rchanges can add to usefulness ofdata.
Cuxtendy, the City of Huntington Beach utilizes other contractors and consultants such
as Geoscience Analytical to provide investigation and engineering design services for the
Christine Drive Gas Anotnaly project. Can an as -needed basis, Brown and Caldwell will
assist the City in evaluatnrg proposed scopes of work for future work proposed by other
City contractors. We will evaluate the proposed work relative to the stated objective for
that work, and provide as independent technical analysis of whether the work will help
achieve the stated project objective, and support the overall approach m understanding
and mitigation of this methane occurrence. We will provide written recommendations
and suggest alternative approaches if appropriate.

Brown and CaldweU will bho assist the City's Project Manager who is overseeing the
progress of this project with as -needed consulting support duzinng the implementation of
studies and mitigation enhancements performed by others contractors selected by the City.
While a cost far Task 5 cannot be provided at this time, our previous informal discussions
with you in January and February 2001 suggest that the City should consider setting aside
approximately 3100,000 as a reserve fund to draw upon for future engineering g services.
The As -Needed Services provided by Brown and Caldwell under Task 5 are not included in
this revised proposal,
CONDENSATION, CoNT> r_T TERMS AND SCHEDULE
We propose that compemation for services described under Tasks 1 through 4 above be on
a time -and -expense basis, not to exceed $46,830.00 as summorig ed in the attached cost
table. The labor rates that will be used for this project are based on Brown and Caldwell's
calendar year 2001 billing schedule. These rates will be adjusted on an annual basis
commencing in January of each calendar year. Some of the proposed services described
above involve considerable uncertainty in the level of effort to satisfactorily complete the
objectives, or involve as -needed services to be conducted at the request of the City,
especially Task 5_ The costs allocated for each task are Brown and Caldwell's best estimate
of the level of effort necessary to complete the task. As the tasks are implemented, we will
notify the City when budget milestones of 50% and 75% are reached. At that time,
additional budget may be necessary to continue the projecs or complete a specific task.
Authorization by the City of additional funding to the contract must be done in a timely
manner as not to stop the progress of the project, and we understand based on our
meetings and discussions with you that such funding will be made quickly available where
warranted to satisfy project objectives. If heading is not assured, we will terminate our
work in an orderly fashion and invoice the City for services rendered.
In conjunction with the revised approach to the scope of services, we have made an
effort to soften our indemnification requirements both in response to the City
Attorney's comments and in an effort to refine how we can provide important
professional services to the City while addressing our risk management objectives.
The three paragraphs below represent the following approach:
■ Brown and Caldwell'-- indemnification and defense of the City is based upon our
proportionate fault (professional negligence).
■ Broom and Caldwell'-- liability to the City is limited to 5250,000. We will be responsible
for our professional fault; however, we are not willing to be subject to unlimited
liability. As it is, the 5250,000 limitation falls within Brown and Caldwell's self -insured
retention and would come directly from our bottom line.

■ Inckmrrihcarian and defense by the City to Brown and Caldwell for third party claims
arising from pre-existing conditions. (The exception is claims by third parries that anise
out of Brown and Caldwell's sole negligence or willful misconduct.) Lawsuits from
homeowners are of pktdcular concern to us.
[Nam: We do not know whether the City tharier allowa for firth indemnification, and at m1d
appreciate advice from the CrtyAttanrey to confirm the City bar appropna& authority to commit to
such a pmmion.]
The specific text requested for the Hold Harmless provision (Section 8) is:
Indemnification of the City
Consultanr agrees to indem ify, defend and hold City harmless from and against liability to
the extent caused by the negligent acts, =ors or omissions of Consultant, its
subcontractors, agents, eolployees, or representatives in the performance of Consultant's
duties under this Agreement. Such negligence shall be measured by standards in effect at
the time services are rendered, not by laser standards.
Limitation of Liability
City agrees, that to the fullest extent permitted by law, Consultant's total liability to City is
limited to $250,000 for any and all claims, damages, losses of expenses (including attorney's
fees) arising in any way ont of the professional services provided under this Agreement.
regardless of the legal theory under which such liability is imposed:
Indemnification by City for Pre-existing Conditions
City acknowledges that Consultant will perform part of the work at locations that may
contain hazardous materL s or pollution conditions ("Preexisting Pollution Conditions'),
and that Consultant had no prior role in the generation, treatment, storage, investigation or
disposition of such materials. in consideration of the associated risks that may give rise to
claims by third parties or employees of City, City agrees to indemnify, defend, glad hold
Consultant harmless (including attorneys' fees and other legal expenses) from any and all
losses, damages, claims, or actions brought by any third party or employee of City against
Consultant or Consultant's employees, agents, officers or directors that result from or are
attributable to such Preexisting Pollution Conditions. City's responsibility under this
provision, however, shall not apply to the extent claims are shown by final judgment to
arise out of Consultant's sole negligence or Consultant's willful misconduct."
Once resolution to the contract language has been made and a signed contract has been
executed between the City and Brown and Caldwell, we are prepared to begin work within
10 worldng days.

PROFESSIONAL SERVICES CONTRACT BETWEEN
THE CITY OF HUNTINGTOI\ BEACH AND
BROWN & CALDWELL TO PROVIDE ENVIRO'NMENTAL
ENGINEERING SERVICES IN SUPPORT OF THE
CHRISTINE DRIVE GAS ANOMALY PROJECT
THIS Agreement is made and entered into this 21st day of
2001, by and between the City of Huntington Beach, a municipal corporation of the State of
California, hereinafter referred to as "CITY," and BROtiVN & CALDWELL, a California
corporation, hereinafter referred to as "CONSULTANT."
WHEREAS, CITY desires to engage the services of a consultant to provide
environmental engineering services in support of the Christine Drive Gas Anomaly Project; and
Pursuant to documentation on file in the office of the City Clerk, the provisions of
the Huntington Beach Municipal Code, Chapter 3.03, relating to procurement of professional
service contracts -have been complied with; and
CONSULTANT has been selected to perform said services,
NOW, THEREFORE, it is agreed by CITY and CONSULTANT as follows:
SCOPE OF SERVICES
Task 1. Review Aerial Photographs.
Objective: Document historical use/condition of the Christine Drive area.
The residential development in the vicinity of Christine Drive was reportedly
constructed in the early 1960s. In previous assessments performed by others, it has been
assumed that the development was constructed over marshland. In order to document the prior
condition of the area and perhaps gain insight for understanding the methane occurrence,
CONSULTANT will review historical aerial photographs of the site with a focus on photographs
taken prior to site development. In order to obtain a comprehensive set of photographs, several
01agree h-own&caldwell
RIS 900: -00-9: ,;1 01
sources of aerial photographs will be reviewed such as the Fairchild collection at Whittier
College, Rupp Aerial Photographs, and UCLA.
The photographs will be examined to document features relevant to the area such
as historical drainage courses, indications of industrial activity or other features that may
contribute to the understanding of the source or distribution of the methane accumulations. A
log of observations of each photograph will be compiled. Copies of relevant photographs will be
purchased to become part of the project file.
A brief letter report will document the overall findings of this review, and will
include the observation log and copies of all relevant photographs.
Task l will be completed within 30 days from the date of the approval of this
Agreement by CITY.
Task 2. HydrogeoloQic Review.
Objectives:
■ Develop a hydrogeologic model of the area.
■ Understand the relationship between the hydrogeology and the methane
occurrence.
CONSULTANT will review the accumulated hydrogeologic data and methane
occurrences to independently develop a hydrogeologic model of the subject area. The model
will incorporate the existing data developed by Keith Tucker for the Southeast Homeowner's
Association, Geoscience Analytical's site investigation results, and other records provided by the
Citv in regards to this site. The goal is to utilize all of the existing data to develop as accurate an
understanding as feasible of the shallow subsurface and to evaluate the control that strata may
have on the distribution of the gasses in the Christine Drive area.
01 agree:hrown&talc%%ell
RLS 9001 -0045' Hof
CONSULTANT will also include in this review an analysis of the data in regards
to the postulation that the groundwater levels rose in the area due to the installation of the sheet
piling along Talbert and Huntington Beach Channels, including critical review of the Bing Yen
& Associates ("BYA") March 1996 study regarding this issue (Talbert and Huntington Beach
Channel Hydrogeologic Study).
Deliverables relative to this task, including identification of data gaps necessary
for a reasoned analysis, are included in Task 4.
Task 3. Engineering Review.
Objectives:
■ Verify accuracy of previous representations of site conditions.
■ Assess effectiveness of existing mitigation structures.
■ Establish knowledge base to evaluate mitigation enhancements.
Subsequent to the hydrogeologic evaluation, the relationship of the subsurface
utility lines/trenches to the methane occurrences and hydrogeology will be examined. The
interpretations presented by Keith Tucker for the Southeast Homeowner's Association and
Geoscience Analytical in regards to the relationship between City utilities and the methane
occurrence will be reviewed. Their presentations of the data will be compared to CITY provided
engineering drawings and the CITY provided hydrogeologic data to check that their
presentations accurately reflect the data and site conditions and for verification that the data
support their interpretations.
A part of this hydrogeologic and engineering evaluation will be to develop
potential scenarios for the source of the methane and criteria by which these scenarios may be
differentiated. An understanding of the ultimate source of the methane may help refine further
01 a@reelhrown&caldwell
KIS 9001-0049'5/1/01
mitigation and planning efforts. The most likely sources mentioned to date include degradation
of natural organic material entrained in sediments associated within an organic -rich depositional
environment upon which the development was built, a sewer leak, or gas migration from natural
petroleum deposits. The existing site data will be analyzed in light of these criteria to see if a
supportable interpretation can be made as to the possible/probable source of the methane.
The design of the existing gas mitigation control structures will also be subjected
to a preliminary review as part of this task. CONSULTANT will provide conceptual
recommendations regarding possible future enhancements of the gas control/mitigation system.
Deliverables relative to this task, including identification of data gaps necessary
for a reasoned analysis, are included in Task 4.
Task 4. Report of Findings/Gap Analysis
Objectives:
■ Present documentation of conceptual model and evaluations described in
Tasks 2 and 3.
■ Identify Data Gaps needed to confidently understand site and gas
occurrences and plan future work.
CONSULTANT will provide a written report outlining the results of the
hydrogeology and engineering reviews and analysis. The report will outline key findings of
CONSULTANT'S independent review, and major areas of agreement or disagreement with
interpretations presented by Keith Tucker, Geoscience Analytical, and Bing Yen and Associates.
In addition to a narrative description of the data reviewed and the conclusions reached, the report
will include cross sections, several GIS maps, and additional drawings to illustrate the site
conditions in a clear and understandable way.

The underlying goal of further analysis at this time is to reach an understanding of
the site conditions (the natural environment and engineering structures) in order to confidently
plan future mitigation based on solid scientific and engineering principles. It is possible that the
existing data are not sufficient to provide conclusive answers to all of the outstanding questions
such as the origin of the methane, factors controlling its distribution, and effective engineering
controls or other means of mitigating the gas accumulation and migration. Therefore, this report
will include identification of data gaps necessary or desirable to better understand and plan future
efforts, along with recommendations of further work to secure the data.
Task 4 will be completed within 120 days from the date of the approval of this
Agreement by CITY.
Task 5. Provide As -Needed Consulting in Evaluation of Future Site Work
Objectives:
■ Evaluate if planned work can help achieve the stated objective.
■ Provide recommendations if changes can add to usefulness of data.
Currently, the City of Huntington Beach utilizes other contractors such as
Geoscience Analytical to provide investigation and engineering design services for the Christine
Drive Gas Anomaly project. On an as -needed basis, CONSULTANT will assist the CITY in
evaluating proposed scopes of work for future work proposed by other CITY contractors.
CONSULTANT will evaluate the proposed work relative to the stated objective for that work,
and provide an independent analysis of if the work will help achieve the stated project objective,
and support the overall approach to understanding and mitigation of this methane occurrence.
CONSULTANT will provide written recommendations and suggest alternative approaches if
appropriate.
