of the BEC or the City, exceeds the limits of the applicant’s other agency permits
the applicant and the City shall meet to assess the regulatory and financial impacts
of the additional disposal work proposed outside those limits.
The ultimate disposal location shall be specifically approved by the City Engineer.
At the August 8, 1995 Beach Erosion Committee meeting, the Committee considered
SDG&E’s proposed dredging program but withheld their decision based on the untimely
submittal of the proposal and a lack of time to adequately review and comment of the
dredge program.

Qn September 6, 1995, the City Engineer, pursuant to the provisions of the SUP, sent a
letter to SDG&E stipulating the content of the 1995/96 dredging program. The provisions
are as follows:
Pursuant to the requirements of Special Use Permit 92-04 and based upon discussions
with the Carlsbad Beach Erosion Committee, the following is your approved 1995/96
dredging program for the outer basin of the Agua Hedionda Lagoon:
b Upon commencement of SQG&E’s dredging program, place the first 150,000 cubic
yards of dredge material beginning at the northerly limits of the permit area (Oak
Street) and deposit the material in a southerly direction building a beach profile of
150 feet from the toe of the seawall.
Deposit the next 200,000 cubic yards of dredge material between the inlet and
outlet jetties of the Agua Hedionda Lagoon western basin.
t-
b Place the remaining material (approximately 50,000 cubic yards) south of the outlet
jetty.
The sand deposition locations established by the City were based on previous offshore
studies completed along the Carlsbad coastline. These reports and studies have indicated
that there is a northerly shift in offshore currents during a portion of the year which would
reduce the potential of sand influx into the lagoon. In addition, material placed between
the jetties would naturally enter the lagoon mouth during this northerly shift in currents.
Another study evaluated the sand migration in the northern portion of the Oceanside
Littoral Cell which indicated that there is a northern drift of sand material in the nearshore
zone amounting to approximately one third of the total gross transport of material in the
cell. It is for these reasons that the Beach Erosion Committee and the City Engineer has
directed that at least one third of the total dredged material be placed along the northerly
limits of the approved disposal area.
In past dredging cycles, SDG&E was allowed to place the sand northerly as the last
operation. in each case the quantities deposited were substantially less than required.
sufficiently short of the inlet jetty will allow natural drift to fill in the beach southerly without
increasing sand flow back into the lagoon.
On Thursday, September 28, 1995, SDG&E was observed by City staff as disposing of
dredged material south of the outlet jetty, at an unapproved location at this stage of the
dredging. A Stop Work order was issued by the City Engineer based on non-compliance
with the provisions of the Municipal Code. Failure to comply with the conditions
established in the SUP constituted a violation of the Municipal Code and is subject to the
provisions of Sections 1.08 and 21.1 10.080. In addition, if the violation is not rectified and
SDG&E continues to dredge in non-compliance with the approved disposal locations,
violation actions will accrue on a daily basis.
Beginning beach fill to the furthest northerly limits will insure deposits and if stopped

Dear Ms. Rauthenkranz:
We represent San Diego Gas & Electric Co. (IISDG&EII). On behalf of SDG&E, and pursuant to Carlsbad Municipal Code section
1.20.60, we hereby appeal to the City Council the conditions ("the Approval Conditionsvf) attached to the City Engineer's
approval of SDG&E's 1995196 dredging program for the Outer Basin of the Agua Hedionda Lagoon, dated September 6, 1995.
Notwithstanding the 10-day time limit set forth in section
1.20,600, the City Attorney has agreed to a waiver of the time limit to permit the Council to consider this matter.

We base this appeal on all of the reasons set forth in our
Pending a judicial resolution of the controversy between Carlsbad and SDG&E, our client proposes to proceed with the
dredging program in accordance with modified order of placement,
as set forth in our October 2, 1995 letter to Mr. Ball.
Specifically, our client proposes, and asks the Council to accept, the following:
(i> SDG&E shall file and pursue with all deliberate
speed an action to determine the jurisdiction of
City over the dredging and deposit activity and the legality of the Approval Conditions;

concerning the effect of tides and sand transport in and out of
the Lagoon.
3, The following are the opinions I ha-= formed, based on
my knowledge and experience.
4. The beaches in proximity to the Plant are part of the
Oceanside Littoral Cell, which extends from Dana Point in Orange
County to Point La solla in La Jolla.
Oceanside Littoral Cell and its relationship to the surrounding
geography are illustrated in Exhibit *V-l", attached hereto and

surf zone which transport sand toward the south, in an action
known as *'Littoral Drift. *'
8. Reversals in the prevailing north-to-south Littoral
Drift of sand are rare and occur in isolated episodes, usually
related tu unusual summer storm activity in the southern
hemisphere, or off the coast of southern Mexico.
9. In a recent meeting of the Beach Erosion Committee of
the CITY OF CARLSBAD ( IrCARLSBADtt) the Conunittee * s expert,
Dr. Chule Sonu, presented an exhibit of one of such rare
episodes, which occurred during the atypical period of 1969-1970. '

River is the Only remaining unobstructed source of river-derived
sand for the Oceanside Littoral Cell.
\
11. The sand from the Santa Margarita River tends to get
impounded at Oceanside Harbor because of a diffraction in the
wave field which, in turn, is caused by the Harbor jetties. The

disruption of Littoral Drift by the action of that diffraction is
the primary cause of erosion on the northernmost beaches of
CARLSBAD. This is illustrated in Exhibit 1t5-51), attached hereto
and incorporated herein by this reference.

to Littoral Drift along the Oceanside Littoral Cell is
approximately 260,000 cubic yards. This number has been con-
firmed by numerous studies and investigations, which in turn are
based originally on measurements at the end of the Cell, which is

average of data taken by scientists over a period of 20 to 30
years. The fact that these measurements were taken after can-
struction of the inland dams is important because the Littoral

The annual movement figure is based on the

14. Because the only natural source of sand to replenish
beaches from Oceanside to the south is the Santa Margarita River,
13
14
which is to the north of Oceanside, the beaches north of the
Lagoon tend to retain more of the limited new sand from runoff
15 than the beaches to the south of the Lagoon. Therefore, from a
3.6
17
18
regional perspective, the most critical need for sand is on the
southern beaches, from south CARLSBAD to Cardiff and beyond.
15. I have been informed by SDG&E that a recent approval of

22
the City Engineer of CARLSBAD requires that SDG&E take 150,000
cubic yards of dredged material from its 1995/96 dredging program
and deposit it on beaches to the north of the intake jetty.
CARLSBAD generally experiences severe erosion of sand in the
23

26
Wihter, but that situation is relieved in the summer. Beaches to
the south of CARLSBAD experience the same severe erosion in
winter, but they have not recovered in recent summers to the
extent that the north CARLSBAD beaches have. This fact was

north CWSBAD beaches that are already relatively advantaged

27. The Lagoon is already subject to the stresses cited
above and it cannot tolerate additional stress. If SDGCE is
required to place 150,000 cubic yards of sand-to the north of the

that sand will return to the Lagoon within the dredging cycle,
and will, in turn, increase the probability of closure of the
Lagoon, which is already a serious risk at this time.

that an average of at least 65% of the sand which is dredged from

approximately 160,000 cubic yards of sand from the Lagoon. It

SPECiAl USE PERMIT NO. 92-04
Dear Mr. Akin:
ihis letter shall serve as official notice that San Diego Gas and Electric Company's
current dredging operation in the outer basin of the Agua Hedionda Lagoon is in vlolation
of the provisions of Special Use Permit {SUP) No. 92-04. Faijure to comply with the
conditions of approval of SUP 92-04 is subject to enforcement actions established in Sections 1.08.01 0 and 21.1 IO of the Carlsbad Municipal Code. Chapter 21 .I 10 was
'adopted pursuant to the legislative author@ set forth in Government Code Sections
65302, S560 and S800 which conferred upon local government units authority to adopt regulations designed to promote the public health, safety and general welfare of its
citizenry. Therefore, SDG&E must cease with current dredging operations until
compliance is achieved.
In 1992, SDG&E applied to the City of Carisbad for a Special Use Permit pursuant to the Ffood Plain Management Ordinance, Section 21 .I 7 0 of the Carlsbad Municipal Code. On February 3, 1993, the Cartsbad Planning Commission approved Special Use Permit
(SUP) No. 92-04, pursuant to Section 21.1 10.140, relative to the maintenance dredging
of the outer basin of the Agua Hedionda Lagoon by SDG8E. The SUP was approved
by Planning Commission Resolution No. 3490 and subject lo the compliance with the
me Gity shall reserve the authority to review and approve the timing of the dredging operation consistent with the time limits outlined in other permits. The City's review and approval shall not be unreasonably withheld
The appiicant shall secure approval from the City Engineer prior to any proposed
yearly dredging operation. The applicant shall apply for approvai at least three
(3) months prior to the requested dredging activity. No dredging activity may take
place unless specific approval is granted.

6, UDon receiDt of the request far approval of a yearly drsdoing operation, City staff
shall refer the request to the Beach Erosion Committee (BECI for consideration. The BEC shall evaluate the request and provide a recornrnendaion on appropriate
location(s) for the deposition of dredged sand. The determination of sand deposition areas shall be analyzed with regard to the state of the beach and the
analysis area begin at the northerly City limit and extends a similar distance south
of the outlet jetty.
me applicant shall maintain a dredging operation capable of depositing sand on
the beach for a distance of one mile from the mouth of the lagoon and consistent
to the approved work limits of the applicant's other agency permits. Where the
need for sand, as determined by the deposition analysis and the recommendation
of the BEG or the City, exceeds the limits of the applicant's other agency permits
the applicant and the City shall meet to assess the regutalory and financial
impacts of the additional disposal work proposed outside those limits.
The ultimate disposal location shall be specifically approved by the City Engineer.
During the public hearing at the February 3rd Planning Commission meeting, SDGSE did not object to the conditions placed in the SUP. In addition, pursuant to Section
21.110.240, SDG&E did not exercise their right to appeal the provisions of the SUP.
Therefore, SDG&E is bound by the conditions of approvd as outlined in the SUP and
+has entered into a contractual agreement with the City to allow for future dredging
activities. It is also noted that SDG&E complied with the conditions of the SUP prior to
the commencement of their 1993/94 dredging program.
On September 6, 1995 the City Engineer issued a letter outlining the provision of the
1995/96 dredging program for the outer basin of the Agua Hedionda lagoon (attached). The sand deposition locations established by the City were based on previous offshore
studies compl&ed along the Carlsbad coastline. These reports and studies have
indicated that there is a northerly shift: in offshore currents during a portion of the year
which would reduce the potmtial of sand influx into the lagoon, In addition, material
placed between tbe jetties would naturally enter the lagoon mouth during this northerly
shift in currents.
Another study evaluated the sand migration in the northern portion of the Oceanside Littoral Cell which indicated that there is a northern drift of sand material in the nearshore
zone amounting to approximately one third of the total gross transport of material in the
cell. It is for these reasons that the Beach Erosion Committee and the City Engineer has
directed ttraf at least one third of the total dredged material be place along the northerly
limits of the approved disposal area.
On Thursday, September 28, 1995, SDG&E was observed by City staff as disposing of
dredged material south of the outlet jetty, at an unapproved location at this stage of the
dredging.

Failure to comply with the conditions established in the SUP constitute a violation of the
Municipal Code and is subject to the provisions of Sections 1.08 and 21.110.080. In addition, if the violation is not rectified and SDG&E continuzs to dredge in non-
compliance with the approved disposal locations, violation actions will accrue on a daily basis. Enforcement actions will be pursued against individuals and the Corporation to
the full extension of the law.
YOU are hereby ordered to cease and desist in operations not in compliance with the
attached September 6,1995 direction. If you have any questions, please contat me at

Carlsbad Ca 92008
After considerable discussion with representatives from San Diego Gas & Electric and the City, the following is the revised 1995/96 dredging program for the outer basin of the Agua Hedionda
Lagoon:
1. During the first phase of the 1995/96 dredging operation, place approximately 250,000 cubic yards of material between the inlet and outlet jetties of the Agua Hedionda Lagoon. Place the majority of this material adjacent to the northern bank of the outlet jetty. The
natural currents in the littoral cell will spread this material evenly between the jetties and reduce the potential of inflow of the material into the lagoon mouth.
During the second phase of the 1995/96 dredging operation, discharge 100,000 cubic yards to the northerly limits of the disposal area at Oak Street. The disposal and placement method shall be determined in consultation with the consulting coastal engineers of both the City and SDG&E. This material shall be placed in a manner which will minimize the potential of reentering the lagoon system. The disposal method shall be finalized no later than November 1, 1995. If it is determined that the 100,000 cubic
yards is in excess of appropriate disposal quantity based on the recommendations of the consulting coastal engineers, the ultimate quantity may be reduced.
During the third phase of the 1995/96 dredging operation, place the remaining material (approximately 75,000 cubic yards) south of the outlet jetty to the Agua Hedionda Lagoon.
The above program must also be reviewed and approved by the Executive Director of the Coastal Commission in compliance with your current Coastal Development Permit.
In addition, this letter officially cancels the Cease and Desist order dated September 28, 1995.
If you have any questions, please contact me at 438-1 161 extension 4391.
