AGENDA TOPICS
1. Chairman Monroy introduced the meeting minutes of May 4,
1989, which were subsequently reviewed and approved by the
Committee members.
2. Chairman Monroy introduced Dr. Choule Sonu of Tekmarine,
Incorporated, who briefed the Committee regarding his recent
reconnaissance observations of Carlsbad's beaches. Dr. Sonu
indicated he believes the sand placement strategies during
the 1988 dredging of Agua Hedionda Lagoon's western basin
have had an extremely positive effect on sand retention from
Ocean Street, south to the SDG&E outlet jetty. The beach
profile has extended slightly in this area and a great deal
of the material still exists locally due to the use of the
cobble. Between the intake and discharge jetties where the
cobble supply is plentiful, the cobble was used to build a
berm which protected the sand behind it from tidal action.
However, scouring appears to be developing at the foot of the
cobble berm. In front of the seawall where there was not a

large supply of cobble, the sand has been taken in much
greater quantities by tidal action into the surf zone. After
one (1) year, a smooth beach profile has developed which
provides both protection and enhancement of recreational uses
for surfers and bathers. There appears to be some temporary
stabilization of the beach in this area for the moment.
The Committee then addressed questions and issues regarding
the Batiquitos Lagoon Enhancement Project's draft
environmental impact report. The Committee's discussion was
focused upon the subjects of the project's sand distribution
scheme, sand retention scenarios, dredging plan, and jetty
structures. After considerable Committee discussion, with
assistance of Dr. Sonu, the Committee approved the following
eleven (11) issues/quest ions/study areas to be identified and
forwarded, formally, to the City of Carlsbad and the United
States Army Corps of Engineers during the public comments
period.
- Investigation of the advantages of distributing the
approximately 3 million cubic yards of sand from
the dredging operations evenly along the entire
length of Carlsbad's beaches, from Buena Vista
Lagoon in the north, to Batiquitos Lagoon in the
south.
Coordination of the material placement from
Batiquitos Lagoon to coincide with SDG&E's Agua
Hedionda Lagoon dredging (every 3 years), and the
Oceanside Harbor dredging by the Corps.
Investigate with the Corps the potential of
extending the beach nourishment from Oceanside
Harbor, southerly, to Buena Vista Lagoon.
Evaluation of the strategic placement of sand from
Batiquitos Lagoon in those areas in which a
plentiful cobble supply exists in an effort to
extend resident life.
Examine the sand grain sizes and relative quality
from the Agua Hedionda dredging by SDG&E with that
of the proposed Batiquitos Lagoon Enhancement
Project's dredged material.
Reconfirmation of the grain sizes and volumes CH2M
Hill estimates from the Batiquitos dredging.

Evaluation of grain sizes within layers to maximize
the availability, placement, and life expectancy
of larger sized material.
Recommendation that the proposed jetty structures
for Batiguitos Lagoon be physical modeled to fine-
tune the engineered placements and lengths in
advance of final engineering.
Recommendation that the proposed jetty structures
be further examined in an effort to determine that
they will not interfere with littoral drift, and
therefore, cause downcoast impacts.
Investigation of the potential for over-dredging
the central and western basins of Batiquitos Lagoon
to produce more volumes of beach nourishment
material.
Recommendation of sand dredging and placement in
one cycle (Winter-Summer), to take advantage of
northerly littoral drift.
Further investigation of the assumption existing
in the EIR that the sand nourishment and retention
scenario proposed in the document, i.e., that the
creation of sand dunes beyond wave impacts, will
only be of benefit to the City of Carlsbad.
Rather, the Committee recommends some additional
discussion regarding the benefits to the entire
region.
RECOMMENDATION TO THE CITY COUNCIL AND THE UNITED
STATES ARMY CORPS OF ENGINEERS OF ALTERNATIVE "A"
IN THE DRAFT EIR/EIS.
3. Chairman Monroy announced to the Committee the upcoming
public forum and presentation from Ms. Katherine Stone,
environmental attorney and coastal activist, to be sponsored
by the Carlsbad Beach Erosion Committee, Thursday, July 27,
1989, in the Carlsbad City Council Chambers. A formal
announcement is forthcoming.
Chairman Monroy discussed his belief that the Committee
should elect a new chairman to begin July 1, 1989. There was
discussion among the Committee members present on this
subject, however, the Committee agreed to discuss it again
at their next meeting.

presentation on July 27th. A special notice will be sent to Committee
members when a date has been selected.
The meeting was adjourned by Chairman Monroy at 8:30 P.M.
