REVIEWED BY: Elias Sassoon, PE, Director of Public Works
APPROVED BY: Doug Willmore, City Manager
ATTACHED SUPPORTING DOCUMENTS:
A. Professional Services Agreement with NV5 (page A-1)
B. NV5 Proposal (page B-1)
BACKGROUND AND DISCUSSION:
The City Council previously approved this project as part of the CIP, and authorized the
expenditure of $250,000 for the Abalone Cove Sanitary Sewer System Rehabilitation
Program.
The Abalone Cove Sewer Maintenance District is a unique system serving 113
developed parcels in an active area, and is maintained by the City. Sewer user fees are
collected from property owners that are being served by the system. Currently, the
Abalone Cove Sanitary Sewer System is in need of improvements to the lift stations and
the pipelines systems. There are four lift stations that need structural, mechanical and
1
electrical upgrades. The galvanized pipes are showing noticeable exterior corrosion and
wall diameter reduction, and need to be replaced with a flexible material. There are also
14 sections of braided stainless steel flexible lines that require replacement. The
polyethylene plastic pipes which serve as the grinder pump laterals are routed both
above ground and underground. Some of these pipes need to be extended in length to
prevent damage due to ground movement. A zero tolerance for sanitary sewer
overflows has been adopted by the State of California, and rehabilitating the system will
minimize the risk of sewer system overflows.
Staff solicited Statements of Qualifications (SOQ) from qualified consultant firms for the
Fiscal Year 2018-19 Capital Improvement Program projects. A total of 21 consultant
firms, including NV5, participated in the process and submitted SOQs. NV5 was
selected for this project based on its expertise, performance and experience, and
provided a proposal for this project. Staff reviewed NV5’s proposal for design of these
improvements and determined that NV5 is suitable to deliver this project.
Staff recommends selecting NV5 to provide complete professional services required for
the design of this project.
The scope of NV5 work will include the following tasks:
Inspect each lift station, and review existing records and field inventory
Develop a lift stations and low pressure pipeline improvements Design
Development Technical Memorandum
Prepare 50% and 100% plans and specifications/recommendations, including Lift
Station mechanical, structural, and electrical upgrades and details, a selection of
Supervisory Control and Data Acquisition (SCADA) alarm notification equipment,
pipeline replacement, construction schedule, and engineer’s cost estimate
Develop and submit the final plans, specifications and estimate , addressing all
comments received from the 100% submittal, in the City’s bid document format
Provide project management during each task
Attend meetings, including project kickoff meeting, committee and progress
meetings (design review, facilities inspections, etc.)
The deliverable will be a thorough engineer’s estimate and a well -vetted set of plans
and specifications for the design of the improvements to Abalone Cove Sewer System.
ALTERNATIVES:
In addition to the Staff recommendations, the following alternative action is available for
the City Council’s consideration:
1. Take other action as deemed appropriate by the City Council.

City of Rancho Palos Verdes
Abalone Cove Sewer System Improvements Design
SCOPE OF SERVICES
I. Project Description
The Abalone Cove sewer system is comprised of three types of subsystems:
Gravity Subsystem: the gravity collection system consists of approximately 19,000 LF of PVC pipe with
71 manholes.
High Pressure Force Main Subsystem: the four Abalone Cove pump stations are located at Thyme
Place, Sweetby East, Sweetby at Altimira Canyon, and Abalone Cove. There is approximately 2,505 LF
of high pressure force main associated with the pump stations.
Low Pressure Subsystem: the low pressure systems include grinder pumps at each property
discharging to a small diameter low pressure force main. There is approximately 20,000 LF of various
material low pressure force main pipe.
The entire Abalone Cove sewer system flows into the Palos Verdes Drive Pump Station, which
discharges through a 6-inch force main to the gravity system connecting to the Los Angeles County
Sanitation District outfall.
II. Brief Description of the work to be performed
A. The Abalone Cove Sewer System includes four lift stations. The two larger lift stations
(Lower Sweetbay and Abalone Cove) have been converted to allow use of 3-phase
electrical power for the duplex 10-HP pumps. The two smaller lift stations (Thyme and
Upper Sweetbay) operate using the originally installed electrical system, which provides
single-phase power to the duplex 7½-HP pumps.
B. In order to address condition and capacity needs at the lift stations, the City has
identified the following recommendations:
Evaluate provision of additional storage capacity to provide at least 6-hours capacity
to allow time for responders to fix or replace pumps, or in the case of a power failure.
Establish a basic standard for the lift pump models and phase the standard pumps
into service. A basic requirement is that the pumps should be interchangeable. This
would allow for a single spare pump of each size to be stored to serve as a replacement
for the 4-pumps needed to operate each of the same size lift stations.
Replace rail systems and other appurtenances that are in poor condition. Repair
wetwell concrete surfaces, and coat with a CIPP or epoxy coating to ensure that they
are waterproof. Upgrade the wetwell level alarms.
Install an SCADA (supervisory control and data acquisition) based alarm system at
each of the four lift stations that will enable real time notification of system problems
and failures.

Post a clear notification system at each pump-station, detailing who to call when an
audible or visual alarm is activated
Place electrical wiring schematics and instructions on how to replace the lift station
pumps in a folder inside each lift station.
Convert the two 7½-HP lift stations at Thyme and Upper Sweetbay to accommodate
three phase pumps.
Replace (2) 10-HP and (2) 7½-HP pumps, and provide a 10-HP and 7½-HP spare
pump.
C. The low pressure grinder pump system conveys wastewater from individual properties to
the low pressure force main system. The low pressure force main (LPFM) pipelines consist
of the following:
LOCATION MATERIAL LENGTH (FT)
Grinder Pump to Main LPFM PE (1.25 “ – 4”) 6,800
Grinder Pump to Main - Connectors Stainless Steel (35x10’) 350
Main LPFM (Some above ground) Galvanized (2” – 3”) 12,815
TOTAL 19,965
The PE pipe is generally in good shape; however, the City has identified 45 grinder pump
LPFM’s that require addition of pipe to accommodate ground movement. Many of the
braided SS connectors have also stretched to their limit due to ground movement, and the
City has identified 14 SS connectors with less than 1-ft of remaining stretch that need to
be replaced, ideally with a less costly flexible material or fittings. Much of the galvanized
pipe has external corrosion due to aggressive soils, as well as internal buildup of deposits.
The City proposes to map and replace all of the existing galvanized pipe with an alternate
flexible material such as PE.
CONSTRUCTION SCHEDULE
The City proposes to construct the lift station improvements during FY 2020, and the low
pressure pipeline improvements during FY 2021. NV5 will prepare two separate sets of
contract documents to allow for independent construction phases.
III. NV5 will perform the following tasks:
1. Project Management and Meetings
A. Meetings: We anticipate attending a kickoff meeting and site visit with Public Works
Department, and additional meetings as needed to inspect the facilities and review
design submittals.
B. Project management efforts are included in each task.
2. Data Review and Compilation
A. Available information regarding the lift stations will be obtained and compiled.
B. NV5 will inspect each station and obtain facility photos as well as dimension
measurements.
C. NV5 will inspect the existing low pressure force main.
