CITY COUNCIL AGENDA
ITEM NO. G -4
TO: CITY COUNCIL
FROM: Public Works Department
SUBJECT: PROPOSAL C -1 OF GRADING AND SILTATION COMMITTEE REPORT
RECOMMENDATIONS:
1. Reaffirm the general policy that maintenance dredging for the
benefit of privately owned piers and slips is the responsi-
bility of those deriving the benefit, regardless of the source of
the material to be dredged.
2. Direct the staff to prepare a formal policy for Council consider-
ation regarding maintenance dredging responsibilities.
3. Authorize the staff to retain the consulting coastal engineering
firm of Moffat & Nichol Engineers to prepare a report on storm
drain impacts and sand distribution in Carnation Cove, for a
maximum fee of $7,500.
DISCUSSION:
A. Introduction
The report of the Grading and Siltation Committee previously approved
by the City Council included proposal C -1, as follows:
"Request the assistance of the U.S. Geologic Survey and the Corps
of Engineers in dredging out the shoals of silt which have built
up at the Bahia Corinthian Yacht Club, in Carnation Cove, and
at Balboa Coves."
The Council action on Proposal C -1 specified that the staff be directed
to make inquiries of the U. S. Government; and that the Public Works staff
be directed to seek a new suggestion to the Carnation Cove storm drain
problem.
In order to discuss the issues the subject has been divided into two
components: (1) maintenance dredging responsibilities, and (2) the Jasmine
Creek storm drain- Carnation Cove interaction.
B. Maintenance Dredging
Precedent and past general policy in Newport Harbor have provided that
maintenance dredging for the benefit of private piers and slips located on
public or private tidelands is the responsibility of those deriving the bene-
fit, not the general public.

Subject: Proposal C -1 of Grading and Siltation Committee Report
Page 2
With particular reference to the U.S. Government, the Corps of
Engineers has indicated that its maintenance dredging responsibility lies
within the main channels, bayward of the Federal project lines. A copy of
a memo from the Marine Director regarding this matter is attached for
reference.
An argument has been advanced by some that maintenance dredging of
silt deposited at City storm drain outlets should be performed by the City.
In general, underground storm drains have merely replaced existing natural
ravines and drainage courses. The usual effect of construction of the
underground drain is to reduce the amount of siltation, not to create a
new source of siltation. Unless a benefit to the general public can be
demonstrated,it is felt that maintenance dredging responsibilities at storm
drain outlets should also lie with those deriving the benefits, as at other
locations.
C. Jasmine Creek Storm Drain - Carnation Cove
Concern has been expressed by residents adjacent to Carnation Cove
about the operation of the Jasmine Creek storm drain, and the impact of
drainage discharges on Carnation Cove. Specifically, requests have been
made that the drain be extended out into the bay so as to reduce effects
on the beach and piers.
The Alderman, Swift, & Lewis (A.S. & L.) design report on the Jasmine
Creek storm drain contains cost estimates for extending the drain. An
extension of 150 feet is estimated to cost $114,000; and an extension of
300 feet is estimated to cost $228,000. The 6- foot - diameter pipe extension
would lie on the surface of the rock bottom of Carnation Cove, and would be
held in place by vertical steel pilings driven into the bottom. At low tides
much of the pipe would project above the bottom, and would be visible to the
extent that it was not covered by sand. The pilings would be highly visible,
and both the pipe and pilings could be hazards to navigation.
The staff has serious reservations about the estimated cost, esthetic
and environmental impacts, navigational impacts, and potential effectiveness
of a storm drain extension.
It is likely also that natural forces other than storm drain discharges
play a major role in determining sand distribution in Carnation Cove. These
forces could include tidal currents, and wave and surge energy entering the
harbor mouth.
Because of the above factors, the staff feels strongly that no commit-
ment should be made to a costly and time- consuming project for modifications
to the storm drain outlet without a much better understanding of the tech-
nical factors involved, and a demonstration that the benefits would justify
the work.

Subject: Proposal C -1 of Grading and Siltation Committee Report
Page 3
For initial evaluation, a proposal for a report has been obtained from
a highly experienced coastal engineering firm, Moffat & Nichol Engineers.
The scope of work would be generally as follows:
1. Qualitatively evaluate the effect of forces affecting sand dis-
tribution in the cove, such as tidal currents, storm drain
discharges, wave energy emanating from the harbor entrance, etc.
2. Consider effects on the beach area and on the adjacent bulkheads
of high rate discharges from the existing storm drain outlet.
3. Qualitatively evaluate the performance of alternative storm drain
outlet /energy dissipation structures such as an extended pipe,
rock jetties, or a reinforced concrete structure adjacent to
the bulkhead; and prepare rough cost estimates of the alternatives.
The fee for the report would be $7,500. A copy of the proposal is
attached for reference.
A copy of a drawing showing the area is also attached for reference.
Larger scale exhibits will be on display in the Council Chambers.

SUBJECT: U.S. ARMY CORPS OF ENGINEERS DREDGING RESPONSIBILITY:
LOWER NEWPORT BAY
background
M
The City of Newport Beach sent representatives to Washington D. C. in
September 1933 to present a report and plans for the dredging of the lower
Newport Bay and to construct extensions to the east and west jetties at the
harbor entrance. The Chief of Engineers, U.S. Army, recommended on September
25, 1933, that a project be undertaken as proposed by local interests. He
established an estimated cost of $1,835,000 subject to the conditions that
local interests contribute one half of the cost of the improvements, not to
exceed :0915,000, and they furnish free of cost to the United States, all the
necessary rights -of -ways and disposal areas for the dredged materials.
Subsequently, the Orange County Harbor District was formed December 1933 and
a public approved bond issue of $640,000 for the proposed improvements to
lower Newport Bay was authorized. The harbor improvements were started in
January of 1935 and were completed in April of 1936. The project undertaken
in between 1935 and 1936 did not dredge the lower bay to the exact design
project depth in all areas. The reason for partial completion of the authorized
project was because the Corps lacked the funding beyond the authorized amount
of 1,835,000 and it was felt that the bay, as dredged by the Corps, was adequate
for a recreational boat harbor. The entrance channel to the turning basin,
opposite the Arches and Lido Village, was dredged to a depth of twenty (20)
feet. The Army Corps of Engineers have maintained that deepening water ways,
contiguous to the main channel, would require new authorization and funding
from Congress.
The Newport Bay harbor lines were revised by the Secretary of War on May 2,
1936, following the completion of the improvements to lower Newport Bay by
the Federal Government and the new Orange County Harbor District. Existing
harbor lines in Newport Bay were re- approved by the Secretary of the Army
on February 15, 1951 and are generally the same to date.
The Army Corps of Engineers have indicated by letter to the County of Orange,
that they have the responsibility for maintaining the main channel to a
depth of twenty (20) feet. In addition, the Corps has acknowledged the res-
ponsibility for maintaining depths in all areas within the Federal project
lines, to at least a depth of minus ten (10) feet.

Discussion:
The City's Grading and Siltation Committee has recommended that the Corps
of Engineers be contacted with reference to maintenance dredging respon-
sibility for shoaling at Carnation Cove, Bahia Corinthian Yacht Club and
Balboa Coves. The shoaling that has occurred in each of these areas, as
identified by the Grading and Siltation Committee, is landward of the U.S.
Project Line and therefore, out of the Corps of Engineers area for main-
tenance responsibility.
Carnation Cove - The Carnation Cove area is over County tidelands
and the shoaling refered to, is considerably landward of the
established U.S. Project Line. The City has consistantly main-
tained that maintenance dredging, in the general vicinity of
piers and slips, is the responsibility of the upland home owner
as a condition of the Harbor Permit or right to use public tide-
lands.
Bahia Corinthian Yacht Club - The Bahia Corinthian Yacht Club
adjoins City tidelands. The City maintains that dredging respon-
sibility rests with the Bahia Corinthian Yacht Club to maintain
adequate depth for the berthing of boats within the Harbor Permit
zone.
Balboa Coves - The water within the Balboa Coves tract is fee
property owned by the adjoining upland property owners. Conse-
quently, maintenance dredging responsibility rests with the
private property owners.

PROPOSAL
CARNATION COVE STUDY
Scope
0
MAY, 1980
Moffatt & Nichol, Engineers offer to carry out an engineering
study of sand distribution in Carnation Cove, Newport Bay. The
scope of work would be generally as follows:
1. Qualitively evaluate the effect of forces affecting
sand distribution in the cove; such as tidal currents,
storm drain discharges, wave energy emanating from the
harbor entrace etc.
2. Consider effects on the beach area and on the
adjacent bulkheads of high rate discharges from the exist-
ing 60 -inch diameter storm drain outlet.
3. Qualitatively evaluate the performance of alterna-
tive storm drain outlet energy dissipation structures such as
an extended pipe, rock jetties, or a reinforced concrete
structure adjacent to the bulkhead; and prepare rough cost
estimates of the alternatives.
Procedure
Since only qualitative results with regard to sand movement
are required and no field work is to be performed, data will be
developed from existing sources. The most useful type of
information will be historical bathymetry; probably some of this
will be available from Corps of Engineers channel surveys.
Analyses will be made of wind, waves, ocean swell, and
tidal currents to assess their role in transporting sand inside
the cove. The drainage watershed will be evaluated as a sand
source. Finally, the effect of the runoff discharge in redis-
tributing sand will be estimated.
If it appears that the discharge may be responsible for
adverse beach changes such as loss of sand at the bulkhead or
shoaling near the floats, solutions will be investigated. These
may include extensions of the pipe or construction of an energy
dissipation device around the pipe mouth. Construction cost
estimates and definition sketches will be prepared for each
solution presented.
Our findings will be described in a letter report, 30
copies to'be furnished. It will include a summary of background
information obtained, assumptions made, and computation pro-
cedures used.
C
Task Breakdown
The working time needed to carry out the proposed program
is estimated as follows:
A. Data Collection: Research files of City, Harbor
Department, Corps of Engineers. Interviews with
residents. 5 man -days.
B. Analysis: Wind, waves, and currents; compilation of
historical changes; local sand source; sand transport.
5 man -days.
C. Designs: Pipe extension and pier; energy dissipator;
cost estimates. 5 man -days.
D. Report Preparation: 2 man -days engineering, 1 man -day
drafting, 1 man -day typing.
E. Meetings: 2 man -days.
Fee
Charges will be based on our standard schedule of hourly
rates, attached. If all of the tasks described above turn out to
be necessary, the total fee would be $7,500. This amount will not
be exceeded without your express approval.
