FROM: Carrie Mattingly, Utilities Director
Prepared By: Jennifer Lawrence, Project Manager
SUBJECT: MONTEREY STREET WATERLINE REPLACEMENT
RECOMMENDATION
1. Authorize the City Manager to award a contract to Cannon in the amount of $59,840 for design
services for the “Monterey Street Waterline Replacement.”
2. Approve a Budget Amendment Request to transfer $59,840 from Water Completed Projects to
the design phase of the project.
3. Authorize staff to advertise for bids and authorize the City Manager to award the construction
contract if the lowest responsible bid is within the Engineer’s Estimate of $336,026.
DISCUSSION
In the past year the ten-inch waterline on Monterey Street between California and Pepper has
broken twice. Businesses in the area were without water and traffic was diverted around this section
of Monterey Street while crews spent several hours repairing the break.
An analysis of the risk and benefit of replacing the waterline was completed after the second break.
It is recommended, although the project is not currently on the list of scheduled waterline
replacements, that, due to age and condition of the existing pipeline, the entire section of pipe on
Monterey between California and Johnson be replaced as soon as possible.
There are two 16” water transmission line replacement projects (Phase I and Phase II) that will be
constructed in the area of this proposed project (see the 2013-15 Financial Plan, Capital
Improvement Plan, page 3-117). These projects are currently in the design stage with Phase I
scheduled for construction in April 2014. Phase II, which includes the intersection of California and
Monterey is scheduled for construction starting in July of 2014. Design and construction of this
proposed waterline replacement on Monterey would be scheduled concurrently with Phase II of the
16” water transmission line replacement to reduce costs and minimize traffic and service impacts.
CONCURRENCES
The Community Development Department has granted a Notice of Exemption for the proposed
project since minimal environmental impacts are anticipated.
FISCAL IMPACT
Staff has received a proposal for design from Cannon, one of the City’s on-call consultants
approved for engineering services (Attachment 1). Funding for the design and construction support
portion of the project is available in the Water Completed Projects Account which has a current
Meeting Date
Item Number Dec. 10, 2013

available balance of $130,553. The construction services portion of the project will begin in fiscal
year 2014-15. Funding will be provided during the 2014-15 budget supplement process from the
Water Fund’s working capital.
The project costs are estimated as shown below. A Budget Amendment Request will be processed
to transfer funding from the Completed Projects account to the project’s design.

Monterey Street Waterline Replacement
ALTERNATIVE
Council could choose to deny funding for this project and pursue construction and design services at
a later date. This option is not recommended due to the two recent breaks in this pipe segment.
Without replacement, this section of pipeline is expected to fail and again cause traffic and water
service disruptions to the community.

SUBJECT: PROPOSAL—MONTEREY STREET WATER MAIN REPLACEMENT
Dear Mr. Horton:
We understand the time-sensitive and critical nature of replacing an old water main in
Monterey Street between California Blvd and Johnson Ave. A recent waterline break along
this section of road resulted in significant road damage, disruption to businesses and
residences, and loss of potable water. Replacing this section of antiquated water main before
another break occurs will result in long-term savings to the City.
In preparing our proposal, we have visited the project site, discussed goals for the project with
City staff, developed a general understanding of the water service area of the water main, and
performed initial utility research along the street corridor. Based on this research we have
identified what we consider are the key elements for the success of this project.
•Water Main Alignment—it is critical to develop a realistic and constructible alignment
for the replacement main. This will require detailed utility research, field verification,
and base mapping in order to confidently choose the preferred location for the new
main.
•Constructible Design—thought needs to be devoted to developing construction and
connection details that can be easily installed in short timeframes. This will minimize
overall disruption to the community (i.e. traffic, businesses, residents and tourists.)
•Project Costs—alternative alignments and construction methods (i.e. trenchless
technology) need to be adequately evaluated in order to balance cost of construction
with community disruption.
Cannon has assembled a team of experienced design professionals with practical, local
knowledge in pipeline design, construction and detailed cost estimation. Our local staff
comes to this project with recent, relevant design experience including the City’s Johnson
Ave. water main replacement project completed in 2011.
The following proposal further identifies our understanding of the project and provides a
detailed scope of work. Considering the importance of sequencing for this project, we have
included a project schedule which shows the design phase of this work to be completed by
March 2014.
We stand ready to assist the City in replacing this critical component of infrastructure.

PROJECT UNDERSTANDING
We understand the City intends to replace a critical segment of existing water main in
Monterey Street as a result of a recent break and the likelihood of another occurring in the
near future. Replacement of this aging infrastructure prior to another break will provide long-
term savings and reliability of service to the Community.
The design work necessary to replace the Monterey Street Water Main includes a topographic
survey, utility research and mapping, potholing, alignment alternatives analysis, plan and
profile layout, connection details, technical specifications, and cost estimates. Preliminary
design criteria are summarized below.
Project Criteria Notes
Diameter 10-inch
Material C900 PVC
Approximate Length 1,040 linear feet
Working Pressure To be determined during design
Surge Pressure To be determined during design
Hydrants Reconnect to existing (1-total). Evaluate additional
hydrants
Service Laterals Reconnect (preferred). Replace if polybutylene or
lead based.
In-line Valves Replace at same locations.
Installation Methods Open-cut and/or trenchless
Street Reconstruction considerations Old concrete roadway underneath. Dowel-in and
replace with concrete to minimize differential
settlement
Known Buried Obstructions Large, existing rectangular box culvert running
parallel to existing main along with City Comm.
(fiber optics)
Traffic Concerns Heavy but plenty of roadway width for one lane in
each direction
Connections Monterey/California, Monterey/Johnson,
hydrant(s), laterals
Other Ongoing Projects in the Vicinity Sewer line replacement at Monterey/California
(Filippin); water line replacement in California
(MNS); storm drain improvements at

SCOPE OF WORK
Cannon’s approach to successful completion of this project consists of providing professional
services in three progressive phases: Preliminary Engineering, Construction Documents, and
Construction Engineering Support. Services will include a kickoff meeting, utility research and
mapping, potholing, design, cost estimates, construction documents, and responses to RFI’s.
Descriptions of our proposed involvement and proposed deliverables are summarized below
within each corresponding project task.
Phase 1. Preliminary Engineering
Task 1. Kick-Off Meeting
We will orchestrate and attend a Project Kick-Off Meeting with appropriate personnel from the
City. This meeting agenda will focus on project understanding, team involvement, project
constraints, and the anticipation of design development impediments. This meeting will also
include project introduction, review of background information and project scope, and an
overview of the project schedule. This meeting represents a key opportunity for
representatives from the City to steer the project and further clarify critical elements of the
scope. We anticipate that a field review meeting may also be of value and we have
incorporated a field walk with the City following the project kick-off meeting into our scope.
Task 1 Deliverables:
• Attend Project Kick-Off Meeting and Field Walk
• Prepare and distribute meeting minutes
Task 2. Utility Research & Base Mapping
We will coordinate with the utility companies and the City to obtain pertinent operations data
and record drawing information of utilities within the project areas. We will review applicable
utility documents, topographic survey, as-built drawings and other available materials provided
by the City to compile an electronic base map for use in the design plans. Potential utility
conflicts and/or relocation requirements will be identified and evaluated as needed to minimize
unexpected design modifications or construction delays.
We will initiate a USA Dig Alert Utility Search and will request that the utilities be marked in
order that the marking can be surveyed into the base drawing.
City Provided Items:
• Access to all available, pertinent record drawings in the City’s database
Task 2 Deliverables:
• Base Map in digital format
Task 3. Topographic Survey
We will prepare a topographic survey of the project corridor showing contours and spot
elevations, locations of existing structures, natural land features, roadways, paving, curb,
sidewalk, and existing utilities, drain inlets and catch basins, manholes and fire hydrants. If
required, we also provide locations of trees (greater than 4” in diameter).
An attempt will be made to correlate data that is collected in the field with the location and size
of all underground utilities gathered through our review of available record documentation.
C10 - 6
Proposal: Monterey Street Water Main Replacement
131033 3
We will utilize record data to show the record street right-of-way to identify the limits of public
property and to establish a boundary of the contractors work area.
Task 3 Deliverables:
• Topographic survey incorporated into the digital Base Map
Task 4. Potholing
Record data research of utility as-built information may fail to accurately identify both vertical
and horizontal locations of subsurface facilities. Where detailed information is required to
construct a tie-in connection or avoid crossing interferences and conflicts, potholing will be
used to verify horizontal and vertical depths. We assumed that 10 potholes will be required
for the project. The type of street pothole repair includes backfill with 2-sack slurry to below
AC grade and HMA patch at 6-inch thick. A no-fee encroachment will be issued by the City.
All traffic control will be in accordance with City requirements.
Task 4 Deliverables:
• Horizontal and vertical measurements using tape measure methods
Task 5. Preliminary Alignment
We will develop a preferred alignment alternative for the new 10-inch waterline within the
project corridor. We will prepare a preliminary plan and information that summarizes our
evaluation of the project’s constraints, which include the following:
• Proposed preliminary water main alignment via open-cut method
• Potential utility conflicts
• Utility location discrepancies
• Trenchless Alternative Evaluation (Swageline)
• Health department and other utility company horizontal and vertical clearance
requirements.
The preliminary plan and constraints information will also memorialize the design and test
pressures, as well as the specified materials for the project. A summary of the City-approved
variances and deviations from standard plans will be included in the analysis. We have
assumed the coordination and processing of Health Department approvals will be completed
by the City. One meeting with City staff is included with this task.
Task 5 Deliverables:
• Preliminary Alignment Information and Exhibit
Phase 2. Construction Documents
Task 6. 75% Construction Documents (Plans, Specifications, and Cost Estimate)
We will submit a “Review Submittal” Design Plans Package at a design and detail level
