STAFF REPORT
Pacific Coast Highway Gravity Sewer
(Plan 401 Gravity Sewer)
Background
The Pacific Coast Highway Gravity Sewer was built in 1936 and consists of
approximately 1810 feet of 30-inch VCP, 3230 feet of 27-inch VCP, 3150 feet of
24-Inch VCP, and 2980 feet of 21-inch VCP and has 38 manhole structures. This
sewer is used to transport wastewater collected jointly from the Cities of
Newport Beach and southerly Costa Mesa's collection system to the CSDOC
Treatment Plant No. 2. The original trunk sewer facilities built within
District No. 5 were all constructed by the City of Newport Beach in 1936.
The gravity system serving District No. 5 is essentially that portion of the
system upstream from each of the three District pump stations in Pacific Coast
Highway (Rocky Point, Lido and Bitter Point).
1989 Master Plan
The 1989 Master Plan (Table 8-1) summarized reaches of the trunk system within
District No. 5 that were deficient in capacity to convey master plan flows,
including the subject gravity line. The hydraulic model analysis supporting the
1989 Master Plan indicated that the original Pacific Coast Highway Gravity Sewer
system acquired from the City of Newport Beach is deficient.
Table B-3 of the 1989 Master Plan recommended system improvements for the
aforementioned deficiencies. This included upgrading the sizes of the Bitter
Point Pump Station line from a 30-inch to a 42-inch, the Superior Avenue to
Newport Avenue (Lido) reach from a 27-inch to a 39-inch, and the Rocky Point
Pump Station to Dover Drive, from a 21-inch to a 30-inch line. (Between Newport
Avenue and Rocky Point Pump Station the line is not hydraulically deficient).
The estimated costs for implementation of the above replacement of the Pacific
Coast Highway Gravity Sewer (Plan 401 Sewer) is $4,300,000 (1993 dollars).
As the Directors are aware, several contracts were designed, awarded and
completed for the replacement of the dual force main system in Pacific Coast
Highway. While working on this system, the gravity sewer was exposed and found
to be in very poor condition. As a result, the Directors approved studies to
determine the condition of the gravity sewer.
In May 1989, a contract was awarded to Robert Bein, William Frost 8 Associates
A...� (RBF) for the preparation of a summary report, including the televising of the
entire 11,000 foot gravity trunk sewer and the preparation of manhole surveys,
to determine the condition and the extent of any required remedial work on the f
gravity sewer in Pacific Coast Highway between Dover Drive and Bitter Point Pump
Station.
The report found that the majority of the, pipeline reaches have both major and
minor circumferential cracks at the joints; several pipelines have severe
longitudinal cracks at the crowns, and several pipelines appear to be broken and
deformed. It also appears that the majority of the pipes are running at 3/4 to
full capacity. This indicates that several reaches have already exceeded their
carrying capacity and as future development occurs, the carrying capacity of
this line will be exceeded. (These observations have been supported by the
findings of the 1989 Master Plan study).
In addition to the pipeline, each of the manholes inspected appeared to be in
poor condition. The majority of the manholes had brick and grout deterioration
along with separation. Bricks were missing and in need of repair. Only one of
the manholes was observed to be leaking but the balance, based on their poor
structural condition, could potentially start to leak in the near future.
RBF's general condition summary is that the structural integrity of the trunk
sewer, along with the majority of the manholes, are in poor condition and
immediate replacement and/or repair is recommended.

MEETING DATE

3: STUDY SESSION RE BACKBONE PACIFIC COAST HIGHWAY SEWER
SYSTEM.
The Directors are well aware that many projects have taken
place over the past eight years in Pacific Coast Highway.
County Sanitation District No. 5 (CSD 5) has completed the
rehabilitation or replacement of the dual force main system
beginning at the Bay Bridge Pump Station, located on the east
side of the Upper Newport Bay crossing of Pacific Coast Highway,
to Treatment Plant No. 2 in Huntington Beach. (The last of
this work was recently completed with the construction of a new
second siphon under the Santa Ana River as part of the Corps of
Engineers reconstruction of the Santa Ana River flood control
channel. )
CSD 5 operates three sewers within Pacific Coast Highway;
the dual force main system mentioned above plus a gravity sewer.
(CSD 6 also owns capacity in these lines. ) The gravity sewer
directs wastewater to one of three pump stations which then
pressurize the water to enter the dual force main system for
delivery to Plant No. 2. The gravity sewer, ranging in size
from 30 inches internal diameter to 21 inches internal diameter,
extends from Dover Drive to the Bitter Point Pump Station (at
59th [extended] ) . The gravity sewer was built by the City of
Newport Beach in 1936.
It has been known for sometime that the sewer would
have to be replaced because of age and increased flows. The
1989 Master Plan estimated that the new gravity sewer would
range from 42 inches to 30 inches in size with replacement cost
estimated at $4.3 million. (CSD 6 will share this cost. ) Staff
had budgeted the replacement for the period 1995-97 in previous
budget estimates, however, the Master Plan estimated the work
January 15, 1992
should be done in 1992-93. Recently, as part of the replacement
of the dual force main system, staff uncovered the sewer and
found it to be in poor structural condition. Because of this,
the Directors last year authorized a television camera
inspection of the sewer which, in fact, found that the 57
year-old sewer is in very poor condition.
The Directors are well aware that in addition to the
numerous sewer rehabilitation projects, Pacific Coast Highway
itself has been rebuilt between the Santa Ana River and Newport
Boulevard. The District wishes to proceed with replacement of
the gravity sewer with minimal interference and disruption to
the new Pacific Coast Highway corridor, and also to complete the
sewer work easterly of Newport Boulevard prior to highway
reconstruction planned by CALTRANS and the City of Newport
Beach.
Attached for the Directors review is a separate staff
report providing further background information on the condition
of the gravity sewer. At the meeting staff will review the
status of the sewer, District alternative plans for replacement
and CALTRANS/Newport Beach schedules for the rehabilitation of
Pacific Coast Highway.

Status Report on District's sewer The Director of Engineering
rehabilitation program for the reviewed the status of the
backbone Pacific Coast Highway District's rehabilitation program
sewer system for the backbone Pacific Coast
sewer system.
Mr. Dawes advised the Directors that many projects have taken place
over the past eight years in Pacific Coast Highway. County Sanitation
District No. 5 (CSD 5) has completed the rehabilitation or replacement
of the dual force main system beginning at the Bay Bridge Pump Station,
located on the east side of the Upper Newport Bay crossing of Pacific
Coast Highway, to Treatment Plant No. 2 in Huntington Beach. (The
last of this work was recently completed with the construction of a new
second siphon under the Santa Ana River as part of the Corps of
Engineers' reconstruction of the Santa Ana River flood control channel . )
He further reported that CSD 5 operates three sewers within Pacific
Coast Highway; the dual force main system plus a gravity sewer. (CSD 6
also owns capacity in these lines.) The gravity sewer directs
wastewater to one of three pump stations which then pressurize the
water to enter the dual force main system for delivery to Plant No. 2.
The gravity sewer, ranging in size from 30 inches internal diameter to
21 inches internal diameter, extends from Dover Drive to the Bitter
�✓ Point Pump Station (at 59th [extended]). The gravity sewer was built
by the City of Newport Beach in 1936.

DISTRICT 5
Mr. Dawes noted that staff has known for some time that the sewer would --_
have to be replaced because of age and increased flows. The 1989
Master Plan estimated that the new gravity sewer would range from
42 inches to 30 inches in size with replacement cost estimated at
$4.3 million. (CSD 6 will share this cost.) He advised that the sewer
replacement had previously been budgeted for the period 1995-97;
however, the Master Plan had estimated that the work should be done in
1992-93. He further stated that recently, as part of the replacement
of the dual force main system, staff uncovered the sewer and found it
to be in poor structural condition. Because of this, the Directors
last year authorized a television camera inspection of the sewer which,
in fact, found that the 57 year-old sewer is in very poor condition.
Mr. Dawes then showed a brief video of the damage and conditions inside
the sewer.
Mr. Dawes also reviewed a schedule of District collection system
projects included in the 1991-92 budget, as well as an updated schedule
which had been prepared that day by the Director of Finance. He
briefly explained some of the reasons that the new schedule reflected a
decrease in the estimated cost of some of the projects.
The Director of Engineering pointed out that the Directors were well
aware that in addition to the numerous sewer rehabilitation projects,
Pacific Coast Highway itself has been rebuilt between the Santa Ana
River and Newport Boulevard. He added that the District wished to
proceed with replacement of the gravity sewer with minimal interference
and disruption to the new Pacific Coast Highway corridor. They also
hoped to complete the sewer work easterly of Newport Boulevard prior to
highway reconstruction planned by CALTRANS and the City of Newport
Beach.
Staff also briefed the Board on the potential impact of the Governor's
proposal to eliminate the Districts' property tax revenues on the
Districts' financing.
Discussion
The Board entered into a lengthy discussion relative to the proposed
rehabilitation program and the best timeframe to construct each of the
projects, and coordination of the projects between the District, City
of Newport Beach and CALTRANS. Directors also pointed out the pros and
cons of doing the construction work at night versus during the day to
avoid the busiest traffic times on Pacific Coast Highway.
Directors asked staff to report back to the Board with plans to
accelerate the necessary design of the needed repairs and sewer
replacement projects in order to complete the work as soon as possible
because of the poor condition of the gravity sewer.

Background
The Pacific Coast Highway Gravity Sewer was built in 1936 and consists of
approximately 1810 feet of 30-inch VCP, 3230 feet of 27-inch VCP, 3150 feet of
24-inch VCP, and 2980 feet of 21-inch VCP and has 38 manhole structures. This
sewer is used to transport wastewater collected jointly from the Cities of
Newport Beach and southerly Costa Mesa's collection system to the CSDOC
Treatment Plant No. 2. The original trunk sewer facilities built within
District No. 5 were all constructed by the City of Newport Beach in 1936.
The gravity system serving District No. 5 is essentially that portion of the
system upstream from each of the three District pump stations in Pacific Coast
Highway (Rocky Point, Lido and Bitter Point).

The 1989 Master Plan (Table 8-1) summarized reaches of the trunk system within
District No. 5 that were deficient in capacity to convey master plan flows,
including the subject gravity line. The hydraulic model analysis supporting the
1989 Master Plan indicated that the original Pacific Coast Highway Gravity Sewer
system acquired from the City of Newport Beach is deficient.
Table B-3 of the 1989 Master Plan recommended system improvements for the
aforementioned deficiencies. This included upgrading the sizes of the Bitter
Point Pump Station line from a 30-inch to a 42-inch, the Superior Avenue to
Newport Avenue (Lido) reach from a 27-inch to a 39-inch, and the Rocky Point
Pump Station to Dover Drive, from a 21-inch to a 30-inch line. (Between Newport
Avenue and Rocky Point Pump Station the line is not hydraulically deficient).
The estimated costs for implementation of the above replacement of the Pacific
Coast Highway Gravity Sewer (Plan 401 Sewer) is $4,300,000 (1993 dollars).
As the Directors are aware, several contracts were designed, awarded and
completed for the replacement of the dual force main system in Pacific Coast
Highway. While working on this system, the gravity sewer was exposed and found
to be in very poor condition. As a result, the Directors approved studies to
determine the condition of the gravity sewer.
In May 1989, a contract was awarded to Robert Bein, William Frost 8 Associates
(RBF) for the preparation of a summary report, including the televising of the
entire 11,000 foot gravity trunk sewer and the preparation of manhole surveys,
to determine the condition and the extent of any required remedial work on the
gravity sewer in Pacific Coast Highway between Dover Drive and Bitter Point Pump
Station.
The report found that the majority of the. pipeline reaches have both major and
minor circumferential cracks at the joints; several pipelines have severe
longitudinal cracks at the crowns, and several pipelines appear to be broken and
deformed. It also appears that the majority of the pipes are running at 3/4 to
full capacity. This indicates that several reaches have already exceeded their
carrying capacity and as future development occurs, the carrying capacity of
this line will be exceeded. (These observations have been supported by the
findings of the 1989 Master Plan study).
In addition to the pipeline, each of the manholes inspected appeared to be in
poor condition. The majority of the manholes had brick and grout deterioration
along with separation. Bricks were missing and in need of repair. Only one of
the manholes was observed to be leaking but the balance, based on their poor
structural condition, could potentially start to leak in the near future.
RBF's general condition summary is that the structural integrity of the trunk
sewer, along with the majority of the manholes, are in poor condition and
immediate replacement and/or repair is recommended.

3 : STUDY SESSION RE BACKBONE PACIFIC COAST HIGHWAY SEWER
SYSTEM.
The Directors are well aware that many projects have taken
place over the past eight years in Pacific Coast Highway.
County Sanitation District No. 5 (CSD 5) has completed the
rehabilitation or replacement of the dual force main system
beginning at the Bay Bridge Pump Station, located on the east
side of the Upper Newport Bay crossing of Pacific Coast Highway,
to Treatment Plant No. 2 in Huntington Beach. (The last of
this work was recently completed with the construction of a new
second siphon under the Santa Ana River as part of the Corps of
Engineers reconstruction of the Santa Ana River flood control
channel. )
CSD 5 operates three sewers within Pacific Coast Highway;
the dual force main system mentioned above plus a gravity sewer.
(CSD 6 also owns capacity in these lines. ) The gravity sewer
directs wastewater to one of three pump stations which then
pressurize the water to enter the dual force main system for
delivery to Plant No. 2. The gravity sewer, ranging in size
from 30 inches internal diameter to 21 inches internal diameter,
extends from Dover Drive to the Bitter Point Pump Station (at
59th [extended] ) . The gravity sewer was built by the City of
Newport Beach in 1936.
It has been known for sometime that the sewer would
have to be replaced because of age and increased flows. The
1989 Master Plan estimated that the. new gravity sewer would
range from 42 inches to 30 inches in size with replacement cost
estimated at $4. 3 million. (CSD 6 will share this cost. ) Staff
had budgeted the replacement for the period 1995-97 in previous
budget estimates, however, the Master Plan estimated the work

should be done in 1992-93. Recently, as part of the replacement
of the dual force main system, staff uncovered the sewer and
found it to be in poor structural condition. Because of this,
the Directors last year authorized a television camera
inspection of the sewer which, in fact, found that the 57
year-old sewer is in very poor condition.
The Directors are well aware that in addition to the
numerous sewer rehabilitation projects, Pacific Coast Highway
itself has been rebuilt between the Santa Ana River and Newport
Boulevard. The District wishes to proceed with replacement of
the gravity sewer with minimal interference and disruption to
the new Pacific Coast Highway corridor, and also to complete the
sewer work easterly of Newport Boulevard prior to highway
reconstruction planned by CALTRANS and the City of Newport
Beach.
Attached for the Directors review is a separate staff
report providing further background information on the condition
of the gravity sewer. At the meeting staff will review the
status of the sewer, District alternative plans for replacement
and CALTRANS/Newport Beach schedules for the rehabilitation of
Pacific Coast Highway. -

STAFF REPORT
Pacific Coast Highway Gravity Sewer
(Plan 401 Gravity Sewer)
Background
The Pacific Coast Highway Gravity Sewer was built in 1936 and consists of
approximately 1810 feet of 30-inch VCP, 3230 feet of 27-inch VCP, 3150 feet of
24-inch VCP, and 2980 feet of 21-inch VCP and has 38 manhole structures. This
sewer is used to transport wastewater collected jointly from the Cities of
Newport Beach and southerly Costa Mesa's collection system to the CSDOC
Treatment Plant No. 2. The original trunk sewer facilities built within
District No. 5 were all constructed by the City of Newport Beach in 1936.
The gravity system serving District No. 5 is essentially that portion of the
system upstream from each of the three District pump stations in Pacific Coast
Highway (Rocky Point, Lido and Bitter Point).
