Authorize the City Manager and Clerk of the Council to execute an agreement with Tetra Tech,
Inc., to provide design engineering services for Well No. 32 Rehabilitation, for a three-year period
from June 21, 2017, through June 20, 2020, with provisions for one two-year renewal option
exercisable by the City Manager and City Attorney, in an amount not to exceed $777,700 for the
term of the contract, subject to nonsubstantive changes approved by the City Manager and City
Attorney.
DISCUSSION
Well No. 32, located at Morrison Park (Exhibit 1), was first constructed in the 1970's. This well,
however, has been inactive for the last nine years due to high nitrate levels which exceed the
State's Department of Public Health threshold of 45mg/L.
The relative location of Well No. 32 is within the well cluster feeding the Garthe Pump Station, the
primary water source for the north and west part of the city. The pump station facility was drilled
in 1982 and water production has begun to decline, making it important to identify additional
water sources for future demands and system reliability. The benefits of bringing this well back
into service include provision of an additional groundwater source for the City's future demands,
reduction in wear -and -tear on other groundwater wells, and water pumping savings.
On December 5, 2016, the Public Works Agency released a Request for Proposal (RFP) for
engineering design services for Well No. 32 Rehabilitation. The RFP was posted on the City's
website and qualified consulting firms were notified. Two proposals were received and evaluated
by a review committee from the Public Works Agency. Each firm was rated according to its
organization, credentials, resumes, references, and rates to provide the required services. Both
of the proposals received were responsive.

y i 'M
The City of Santa (City) operates a potable water
distribution system that serves over 44,000 water
services. The City's potable water is obtained
either by pumping from 21 existing groundwater
wells or imported from several Metropolitan Water
District connections. The City has some wells that
produce groundwater with elevated nitrate levels.
The City has developed a Nitrate Blending Plan
and mixes the high nitrate groundwater with low
nitrate groundwater. Well #32 has elevated nitrate
levels. Well #32, located at Morrison Park, has
been inactive for over the past nine years due to
low operating efficiencies and high nitrate levels.
The City desires to increase their groundwater
pumping capacity and lessen their reliance on
imported water. The intent of this project is to
rehabilitate Well #32 and place it back into service.
Instead of treating the high nitrates at the well site
and impacting Morrison Park, the City intends to
incorporate Well #32 into the City's nitrate blending
plan. Water from Well #32 will be pumped to the
John Garthe Reservoir site. The City blends low
nitrate water from Well #36 and #39 (located at
the John Garthe site) with higher nitrate water from
Well Nos. 18 and 24.
The following are typical key issues which we
believe must be addressed to successfully
complete design services:
Meeting schedule
19 Coordination with the City, reviewing agencies
and permitting agencies
• Utility coordination and conflict resolution
• Potholing of conflicting utilities
• Accounting for traffic control during alignment
selection
all Analyzing alignment alternatives
a Providing construction phasing
Hydraulic calculations
Facility layout
is Operator safety and maintenance friendly
. Structure aesthetics match surrounding
neighborhood
One of the key issues on this project will be considering the impacts to Morrison Park and
incorporating the park's took and LID themes into the design.
251-12
We have broken down our approach into three
parts, Well 32/Morrison Park, the conveyance
pipeline and the John Garthe Reservoir site. Each
element has challenges that the project team will
need to evaluate and work through with the City,
Summarized below are the key critical elements
that the project team has identified for each site:
1. Incorporating an aboveground well facility
that is functional and easy to maintain while
maintaining the use and functionality of Morrison
Public Park,
2. Incorporating the recently constructed low
impact design (LID) in and around the park's
parking lot and incorporating the LID design
into the new improvements and carrying the
landscaping theme throughout the new well site.
3. Identifying the construction impacts to the park
and surrounding residential area and develop
criteria that mitigates/minimizes these impacts to
the park use and the residents.
Well #32 Rehabilitation Engineering Services
2. Santiago Creek crossing whether the bridge can
be utilized or the pipeline needs to be bored and
jacked below the creek crossing.
3. Traffic control on Bristol Street and Memory
Lane. Bristol Street is a heavily congested utility
corridor and a major thoroughfare for traffic.

City of Santa Ana
Successful implementation of the project will
involve resolution of several key issues. We
believe Tetra Tech has an unparalleled grasp of
these issues based on our overall experience,
capabilities and familiarity with other City
projects, personnel and policies. Our approach
to resolving project issues is summarized in the
following pages;
WELL #32 SITE LAYOUT
Layout the rehabilitation equipment and
determine the minimum impact to the park
Locate the new building to minimize impacts
to pedestrian, bicyclist, and vehicle traffic to
the park. The new building will have a larger
aboveground footprint that will impact the
existing driveway approach. There are existing
mature trees that prevent the driveway from
being widened any further. We will work with
the City to determine the approach that both
maximizes access to the park and the well
building.
Provide concept sketches for the construction
access and staging within the park, Identify loss
of parking stalls and required work area. The
City may also want to consider negotiating with
the adjacent church and utilize a portion of their
parking lot to provide a construction staging
area.
Provide concept sketches for final site layout
to provide the City access to the wellhead and
piping for future maintenance and rehabilitation.
Impacts to the Park
• Review interim impacts during construction.
Utilize sketches and identify work area and loss
of use, Provide estimated construction durations
for each phase and the impact to the parking
lot during each phase of construction. One
approach to consider is to close the southerly
driveway in its entirety and utilize only the
northerly driveway accessible to two way traffic
and partially close the parking lot, A second
alternative is to close the parking lot during the
duration of construction and utilize street parking
to facilitate construction activities and mitigate
risk to public exposure to construction activities.
• Define work area and define a perimeter to be
secured to protect the public use of the park
while construction activities are occurring.
Restore the LID improvements at the park
disturbed by construction activities and
incorporate the LID elements into the new well
site, This includes bioswales, drought tolerant
landscape, pervious pavement, and pavers.
Aesthetics
Discuss options for securing the site and
minimizing unpleasing aesthetics such as
chainlink fencing.
Provide two renderings for the building
architectural treatments, The City desires to
snatch the surrounding residential area. The
houses in the area have California gables and
251-14
hipped roofs, The City facilities are typically
CMU buildings.
- We will provide options such as a gabled
roof and a flat roof with a parapet for the
City to consider.
- We will provide options for the building
exterior such as split face block with a
texture change along the Fall height to
visually break up the wall face.
- Pilasters can be provided for structural
relief
Hydraulics
WELL. #32 SITE CROSS SECTION
Well pump will be selected based on the City's
groundwater data and the existing pump design,
Pumping curve for the well pump shall be able to
efficiently pump over the full potential operating
range due to the static water fluctuations,
N Select pumps from City's latest preferred
manufacturers, including the anticipated delivery
time.
Work closely with the City on selection of
equipment for the controls and SCADA. The
City has been working very diligently to
standardize their equipment for their operation
and communications.
Prepare an operational narrative during design
with the City We have worked through this
process on recent projects with the City and
understand the need to discuss and document
Well #32 Rehabilitation Engineering Services
how the well will operate and establishing the
initial set points for the instrumentation. This is
an important step as it memorializes decisions
and facilitates start up.
Write procedures for factory and field testing.
We have also been involved in this process
with the City on several recent projects and
understand the benefit of this effort to confirm
that what is being specified is being provided
and that it will work as expected prior to
installation in the field and then the testing
parameters to test the equipment once installed
to verify its function in the field. This goes a long
way in streamlining the commissioning process
of the new facility into the City's system.
Coordinate with SCE. This will involve any
modifications to the existing site service and
necessary power interruptions.
Pipe Design
251-15
CONVEYANCE PIPELINEALIGNMENT
Perform hydraulic calculations to size the
pipeline and determine if a pressure sustaining
valve will be required. Based on our past work
at the John Garthe Reservoir site, constructing
a "goose -neck", piping brought above ground
to create a high point, is an effective way
to establish a consistent HGL and keep the
pipeline full.
City of Santa Ana
If Select pipeline material, At pipes less than
24 -inches in diameter, PVC and ductile iron pipe
are the two most economical choices,
Select an alignment to minimize impacts to
traffic.
kig Identify any critical crossings that result
in significant risk during construction and
recommend "potholing", physically locating the
utility vertically and horizontally in the field.
is Identify locations for appurtenances and their
impacts. An example is an air and vacuum
valve location relative to existing parking or a
blow -off located near a storm drain or sewer.
Construction Phasing
0 Identify Schools, Emergency Facilities and
Public/Community Centers. (here is an existing
church adjacent to the project site and another
along Bristol Street near the Santiago Creek
Crossing. Santiago Elementary School is
located south of the John Garthe Reservoir site.

Over the years, Tetra Tech has established
well defined, rigorous procedures for project
management. These techniques have been
developed and refined and have contributed to our
success and reputation. The keys to our project
management system are communications, project
planning, monitoring, and quality assurance,
The Tetra Tech team's goal is to keep the City
staff "in the loop" from Day One of the project.
Communication tools include the formal progress
reports afforded through our project management
system and an informal give-and-take approach
starting with Tom Epperson, our Project Manager,
and extending to every member of the Tetra Tech
team. At the project's outset, the chain of command
and appropriate communication methods will be
agreed upon and can be as formal or as informal
as the City desires.
We will use the entire communication spectrum.
We will conduct formal meetings with agenda
and typewritten notes, and we will use informal
meetings with notes to file. We also will have
documentation of telephone communications,
with notes to file or letters of understanding
as appropriate follow-up. Another important
communication link will be our e-mail system.
We are proposing to use e-mail to keep the City
aware of the status of the project. Every two
weeks, Tetra Tech will prepare a brief (one or two
paragraphs or bullet items) e-mail summarizing
the following: activities completed in the previous
week; the activities planned for the upcoming
week; any critical decisions that need to be made;
and schedule of upcoming events/meetings. In
addition, each month we will prepare a project
status memorandum containing the following:
summary of project schedule; description of key
issues/concerns which have surfaced along with
proposed options and solutions; and a project
status summary report showing current schedule
and budget.
Well N32 Rehabilitation Engineering Services
N # lit 1. +. # '
The key to any successful project is good
communications. As our project partner, we
propose to involve City staff in open, honest
communications from the very start of the project.
Our communications will include the following:
• Weekly E-mail Report outlining progress and
actions for following week
• Monthly Report outlining progress, budget, and
potential changes
• Monthly Schedule updates
• Regular Meetings with City staff
• Project Documentation available upon request
All information can be provided electronically
via e-mail or through a website portal. At each
meeting our team will have our project manager
and key design staff present to facilitate the
discussion. We encourage the City to have at least
one representative from Engineering and one
from Water Resources present at each meeting.
However, we welcome as many City staff who
have ideas and input on the project to attend our
progress meetings.
Our team clearly understands the importance of
this project and the importance of ensuring the
City receives a quality product, We have assigned
a QA/QC Manager, Mr. Steve Tedesco, who has
over 34 years of experience. His team also includes
experienced experts in all areas of design and
construction. Mr. Tedesco will ensure that all the
project goals are met,
A detailed Quality Control/Quality Assurance Plan
will be prepared and submitted for review. This
plan establishes lines of communications and
procedures for ensuring quality during all phases
of the project's design and construction. In keeping
with our open communications policy, all of our
Quality Control documents will be made available
251-17
City of Santa Ana
throughout the project, We believe that it is in our
best interest to have our clients fully informed
and up to date on our quality control process.
Information including design reviews, responses
to comments and redline plans can be provided in
either hard copy or electronically.
We will encourage the City staff to let us know
whenever they need more information or whenever
they are unsure about the quality control of the
project. Our goal is to work with City as partners
on the project from Notice to Proceed through
completion.
V Task 1: Project
Agency Coordination
Kick -Off Meeting
Upon receipt of a written Notice to Proceed from
the City, a kickoff meeting will be conducted with
the City Public Works Agency staff to review the
Scope of Services, develop an overall Project
Schedule and confirm the deliverables. The Project
schedule should include each task, milestones,
critical path designation and a schedule for
progress meetings.
Multi -Agency Coordination
Tetra Tech will coordinate with the involved
agencies to obtain their input and include them in
all critical decision making. This includes internal
City departments as well as external jurisdictional
agencies. Based on our understanding the
following agencies are project stakeholders and
required coordination: Public Works, Water
Resources, Parks and Recreation, Building
Department, Traffic, Regional Water Quality Control
Board, Orange County Water District, Division
of Drinking Water, Orange County Flood Control
District and adjacent property owners. Per the RFP,
we have assumed up to six meetings.
Tetra Tech will organize all meetings including
preparation of agendas, meeting minutes and
distribution of all documentation to all attending
parties or as required.
Project Milestone/Monthly Meeting
Tetra Tech will present regular Project progress
report(s) to the City staff each month or as
otherwise agreed upon with the Project Manager
ensuring that City staff is included in all regularly
scheduled progress meetings. Tetra Tech will
organize these meetings including preparing
agenda(s), compiling meeting minutes, and
distributing the minutes to all attending or as
required. We have assumed eight (8) meetings.
V Task 2. As -Built and Utility
Research
Tetra Tech will conduct As -Built and utility research
within the Project area. Tetra Tech will conduct
thorough utility search on the proposed pipeline
alignment consisting of:
1. Contacting Underground Services Alert (USA)
for a computer printout of all utilities registered

2. Send preliminary notice to each utility
requesting utilities information
3. Send second utility notice including preliminary
plans requesting the utility verify locations of
their facilities
4. Send third utility notice including final plans
to each utility for their information and
coordination during construction.
We will research all applicable agencies and utility
company records and prepare a complete list
of all underground and overhead utilities in the
Project area. In addition, we will request from the
underground and overhead utility companies' near
term (next 5 years) improvement information and
schedule.
Upon completion of all required research of
underground and overhead utility companies, we
will provide a comprehensive list of information
251-18
obtained including any planned near term
improvements. Tetra "tech will prepare a complete
list of all As-Built/Record Drawings found, what
agency they were found in and this information shall
be referenced in the Basis of Design and final Plans

striping, raised islands and above ground visible
utilities. We have assumed an area immediately
around the well site and the parking lot at Morrison
Park, the limits of the pipeline alignment from
back of walk to back of walk and the front area
of the John Garthe Reservoir site. In addition,
field topographical survey work will be performed
to identify BC and FC of all curb returns, light
poles, improvements, surface breaklines, striping,
sidewalk, ADA ramps, etc. -above ground and
underground facilities (any that are marked by
others), all utility manholes and pull boxes, and the
dipping of the manholes.
Tetra Tech will develop a potholing location plan
based on our utility research and alignment
analysis. Tetra Tech will schedule the potholing
activities with the City's Project Manager a
minimum of two (2) weeks in advance. Traffic
control plans related to potholing activities will
be submitted to City staff for review. We have
assumed the development of three typical plans, If
site specific traffic control plans are required, Tetra
Tech will prepare a fee once the locations have
been determined. All potholing Information will be
logged and included in the Basis of Design and
on the Final Design Plans. Per the RFP, we have
assumed a maximum of twenty (20) potholes will
be required. We understand that we are required
to obtain permits and pay all applicable fees for
the potholing activities. Backfill and paving will be
as required by the Permitting section of the Public
Works Agency. The pavement section shall match
the existing pavement thickness at a minimum. We
have assumed hot mix asphalt replacement will be
required.
Well 0'32 Rehabilitation Engineering Services
Metra Tech will research available records at the
City to verify the existing right-of-way for the project
area and confirm ownership of the right-of-way.
We will review the available information and will
inform the City of any issues of concern regarding
potential problems having to do with prior rights,
license agreements, encumbrances, etc.
Task 3. Geotechnical
Recommendations
Tetra Tech will be responsible for conducting
necessary geotechnical testing to determine
the existing pavement and base thickness, sub -
grade soil type and evaluation of the structural
section's condition. Field and laboratory testing
will be performed as necessary to recommend
pipe bedding requirements, pump house
foundation requirements, excavation and shoring
requirements, retaining walls as required and a
new pavement structural section throughout the
Project limits, Foundation design analysis, will
be performed to provide earthwork/structural
recommendations, pipe bedding requirements,
and pavement reconstruction details for the
construction of the Project.
Geotechnical testing on sampled earth materials
for sol classification will be performed to evaluate
engineering properties. The test includes moisture
content and dry density, gradation, consolidation,
direct shear, R -value, and corrosivity (chlorite
and sulfate content, minimum resistivity and pH).
Geotechnical hazards at the project site will be
evaluated and geotechnical recommendations
for design and construction of the project will be
prepared. The report will include: site conditions,
geologic hazards (fault rupture, ground shaking,
liquefaction and tsunami), seismicity, foundations,
lateral earth pressures, corrosivity, concrete type,

251-19
City of Santa Ana
We have assumed four (4) borings, one located at
the Well #32 site drilled to a depth of 25 -feet, two
(2) borings at the bridge crossing each drilled to a
depth of 30 -feet and one (1) boring within Memory
Lane drilled to a depth of 10 -feet for the proposed
pipeline,
We have assumed the following: field exploration
can be performed during the daylight hours on
weekdays, there will be a no charge permit from
the City of Santa Ana, identification, handling
and treatment of materials that need to be
environmentally addressed are beyond the scope
of work, we will request the use chalk based paint
for USA marking and the removal of USA markings
is not included in our scope of work.
Tetra Tech will prepare traffic control plans for all
geotechnical field work and will be responsible
for notifying the Project Manager two (2) weeks
in advance of any geotechnical field work being
conducted. Traffic control plans will be submitted to
the City staff for review, We understand that we will
be required to obtain permits and pay all applicable
fees for all geotechnical potholing. Backfill and
paving will be as required by the Permitting section
of the Public Works Agency. The pavement section
shall match the existing pavement, section at a
minimum
Task 4. Well Assessment
including Operations and
Capacity
Tetra Tech will use as -built plans, survey and
conduct any necessary field reviews to evaluate
the existing well operations and understand
the site constraints. We will coordinate all field
investigations of the existing well with the City's
Project manager. The City shall supply a "down
hole" inspection video profiling Well #32.
We recommend the City consider performing
the following activities for the Well #32 profiling.
These activities will provide the information we
need in order to provide recommendations for the
rehabilitation of the existing well.
We recommend the City perform the following:
With the pump installed in the well, collect
a groundwater sample for bacteria/biofilm
speciation analysis by a laboratory to help
determine the presence and type of iron -related
bacteria, sulfate -reducing bacteria, and/or
slime -forming bacteria that may be present in
the well. The water samples would be analyzed
for their potential to biologically generate and
abiotically precipitate various minerals in the
well casing and the surrounding gravel pack
and the adjoining formation materials under
various pumping and non -pumping conditions,
Clearly, the groundwater samples must be
sent to a laboratory that specializes in such
testing and Water Systems Engineering (WSE)
laboratory is one such laboratory that can be
used for this type of analysis.
2. Conduct a dynamic flowmeter (spinner) survey,
to determine the pre -rehabilitation down well
flow regime,
The City might also want to consider removing the
pump and obtaining the following information:
When removing the pump motor, column and
bowls from the well, inspect and measure all
apparatus (both in the field and at the pumping
contractor's shop); examine the scale from the
pump apparatus and possibly send samples
of the scale to WSE for specialized laboratory
analysis.
2. Sound the bottom of the casing to determine
the amount of sediment fill and then bail
that sediment from the bottom of the casing;
examine the collected sediments and possibly
conduct laboratory analysis (if deemed
necessary).
3. Perform a Casing Inspection Thickness
Measurement (CITM) survey following removal
of the permanent pump. This type of survey
allows for the measurement and recording of
the current thickness of the walls of the steel
well casing, which can be used to compare
to the reported thickness of the walls of the
installed casing. Thus, this survey can be very

casing where corrosion may have removed a to, such issues as:
significant amount of metal, which could result
in the eventual formation of holes in the casing. 1 • An overall evaluation of the existing Well station
based an current design standards.
We would be glad to meet with the City to discuss
the advantages of removing the pump and the
additional data that can be obtained from these
tests.
Task 5. Civil & Operational
Project Design Standard and
Criteria
Tetra Tech will work with City staff to determine
the applicable design standards and criteria in
addition to those defined by the Study. We will
consider other possible agency design criteria and/
or standards as necessary. A maximum of three
3 -hour workshop sessions shall be conducted with
the Project Manager, City Operations staff and
the Tetra Tech design team. We will organize the
meeting including obtaining background information
for discussion, preparing the agenda, compiling
meeting minutes and action items, as well as
distributing the minutes as required. Elements to
be discussed shall include, but not be limited to,
operational parameters, ideal control conditions,
and operator experience,
Task 6. Basis of Design
Upon completion of Tasks 2 through 5 above,
Tetra Tech will prepare a Basis of Design Report
including elements and findings from all of the
Tasks. The Basis of Design Report shall summarize
all of the alternatives and outline the agreed upon
alternative including reasons why the alternative
was chosen. The Basis of Design includes 30%
drawings of the chosen alternative including all
proposed improvements, The Basis of Design
Report shall be stamped and signed by a California
Registered Civil Engineer. Prior to completion of
the final Basis of Design Report, Tetra Tech will
prepare and submit for review a draft Basis of
Design Report to City staff,
2. Make recommendations for Well #32
improvements including site alternatives (two
minimum) for the building as well as related
discharge piping, Propose possible building
architectural features that can be incorporated
into the local neighborhood surroundings and
provide concept drawings of the new building.
We have assumed we will consider two roof
type options — a gabled roof and a flat -top roof
with a parapet. We have also assumed that
the building will be a CMU building, similar to
other City facilities. We will work with the City
and discuss building aesthetics and what can
be cost-effectively accomplished to better
assimilate the building into the park and the
surrounding residential area. We have assume
the preparation of two renderings, one for each
building type.
3. Identify new Well #32 station improvements
needed to improve operations, reliability, and
safety. The City would like to re -develop this
Well. Inform the City of the ideal method for
rehabilitation upon review of as -bunts and well
survey video. In addition, the criteria as defined
In the Study shall be met, although additional
improvements related to the selected design
criteria may exist, Note: this well site is not
expected to have a permanent backup power
system on-site.
4. Prepare preliminary electrical design plans for
the motor control center, Well #32 RTU control
panel, Garthe Pump Station RTU control panel
and related appurtenances, The City desires
that the existing motor control center (MCC) at
Garthe Pump Station remain in place and be
tied into the new RTU panel.
5. Make recommendations for communications
between Well #32 and Garthe Pump Station.
We will look at two alternatives for stable
communications between both sites: radio
251-21
City of Santa Ana
and fiber optic. The City has traditionally
used radio but prefers to install buried fiber
optic cables for communication between
these sites, Identify all requirements for the
options described including maintenance and
operation related constraints. We understand
that the City generally uses MDS NET II radio
communications for site to site/home SCADA
communications.
6. Prepare a preliminary underground data
communication pipeline network plan at
the John Garthe Pump Station. Tetra Tech
will prepare a plan that identifies how the
existing wells communicate to John Garthe
Pump Station and how the new Well #32 will
communicate to the pump station. All wells
shall communicate to the main RTU at John
Garthe Pump Station. Tetra Tech will provide
recommendations for improvements to the
communications between the existing wells
and the John Garthe Pump Station. The
improvement of these communication systems
are beyond the scope of this project.
7. Prepare preliminary onsite sodium hypochlorite
generation plans to disinfect the water used to
fill John Garthe Reservoir.
8, Identify hydraulic conditions with the selected
alternative to use in conjunction with the
City Hydraulic Model to ensure satisfactory
operations under normal operating conditions.
We have assumed the following model runs
with all the wells running at once is the worst
case scenario, We will then run models without
each of the high nitrate wells, Well #18 and then
Well #24. We have assumed that Wells #36
and #39 will also be running since they have
the low nitrate water. In the event that the pipe
discharge line to Garthe Reservoir Is used to
increase system headloss, material fatigue shall
be considered a factor when selecting the pipe
line material.
9. Prepare a schedule for Garthe Pump
Station and Well #32 Operational Functional
Specification and related deliverables for
control programming related items.
10. Prepare preliminary horizontal alignment
and vertical profile of water distribution main
upgrades including all utility relocations. Minor
storm drain improvements will be required
for the drain to waste line during well startup
procedures. We have assumed that we are
tying into the existing drainiine and that a new
drain line is not required,
11. Well pumping strategies shall be identified. Care
shall be taken to limit well pump cycling given
the operating constraints identified in the Study.
12. In the event that a pressure reducing/sustaining
valve is determined to be necessary at John
Garthe Reservoir per Alternative One (1) of
the Study, site improvements and yard piping
improvements will be necessary at the John
Garthe Reservoir site. In addition, any site
automation required to operate this valve both
locally and through SCADA shall be subject to
the requirements listed in the PLC Panel Design
and Control Strategies section of the RFP.
13. Prepare park site improvements, preliminary
horizontal alignment and profile of the parking lot
that will be altered due to the construction and
by adding a new well building at Morrison Park,
14. Preparation of a preliminary estimate of probable
cost.
15, Preparation of preliminary staging for
construction including a traffic management plan
and traffic control plans.
16. Outline the preparation and submittal process
of all required permits associated with getting
the project approved and ready for construction.
This Includes estimated time frames for
processing said permits.
17. Prepare required documents and assist in
Environmental approvals. In the event that an
Environmental Impact Report (EIR) is deemed
necessary, all necessary documentation will be
prepared as required by CEQA. An initial study
and mitigated negative declaration has been
included in our proposal fee. A fee for an EIR
shall be an optional item in the event that an EIR
is required.
251-22
Tetra Tech anticipates preparation of an Initial
Study (IS)/Proposed Mitigated Negative Declaration
(MND) for the Water Well #32 Project as stated
in the RFP and per the Public Resources Code
Section 21080(c) and CEQA Guidelines Section
15070.
The scope of work to prepare the IS/MND follows.
Technical studies for air qualitylgreenhouse gas
and noise are included, as well as a biological
resources letter report, and responses to agency
and public comments. The five tasks in the scope
of work are as follows:
Task 1. Project Initiation and Organization.
Tetra Tech will perform a site visit, review project
plans and reference materials, assess additional
data requirements, and attend a kick off meeting
for the environmental analysis effort associated
with obtaining the required CEQA clearance for the

Task 2. Prepare Project Description, Based
upon the site visit and review of project and
reference materials, a draft project description for
the project with supporting Site Plan exhibit will be
prepared for review by the project team to confirm
its accuracy and completeness. The finalized
project description and Site Plan will form the basis
for the environmental documentation.
Task 3. Prepare and Submit Administrative
Draft ISIMND. A complete Initial Study (IS)/
Proposed MND will be prepared, using the CEQA
checklist. It is anticipated that the following
technical studies will be required to support the IS/
MND: 1) a construction -phase technical analysis for
fugitive dust and greenhouse gas emissions; and
2) a construction -phase noise impact assessment.
A brief biological resources letter report will also be
prepared. Tetra "tech will attend one meeting at the
City of Santa Ana to go over City comments on the
Administrative Draft IS/MND. Three hard copies
and electronic PDF files of the Administrative Draft
IS/MND will be submitted to the City of Santa Ana.

Task 4. Prepare Revisions, Produce, and
Circulate Draft IS/MND. Revisions to the
Administrative Draft IS/MND will be made in
response to one set of comments by City Staff.
Three hard copies and electronic PDF files of the
Draft IS/MND will be provided to the City. A one-
page summary of the document will also be provided
for use in newspaper advertisements and public
notification efforts by City Staff. It is assumed that
the City will prepare the distribution list for public
distribution of the IS/MND (with Tetra Tech input),
and be responsible for the posting of all required
notices,
Task 5. Prepare Draft Responses to Public
Comments, and Compile and Submit Final
ISIMND. Immediately following the end of the
public review period, Tetra Tech will prepare
written responses to any comments received on
the environmental document. For the purpose of
estimating cost for this task, it is assumed that no
new analysis or substantive changes to the existing
analysis in the IS/MND will be necessary, and that
the collective responses can be prepared within a
maximum 12 hours by technical staff. If the volume
of comments either exceed the predicted amount, or
are less than predicted, this cost item would need to
be adjusted. Ms, Johnson will attend one. meeting at
the City of Santa Ana to go over City comments on
the Draft Responses to Public Comments, and one
City of Santa Ana public hearing for adoption of the
MND. Three hard copies and electronic PDF files of
the Administrative Final ISIMND will be submitted to
the City.
