PMA Job #39021
Dear Mr. Carlson,
PMA Consulting, Inc. is pleased to provide this report in accordance with Section
21.30.15.E.3 of City of Newport Beach Municipal Code.
STATEMENT OF THE PREPARER’S QUALIFICATIONS
Plamen Petrov, P.E., the preparer of this report, holds a Master of Science in Structural
Engineering from University of Architecture, Structural Engineering & Geodesy of Sofia, Bulgaria,
and is a Licensed Civil Engineer by the State of California Certificate No. C66947. For the last 21
years of his professional career, he has been actively involved in the design and entitlement of
many Waterfront Developments such as custom homes, seawalls, piers, platforms, floating docks
and marinas. A great number of Bulkhead Condition Reports prepared by him have been reviewed
and accepted/approved by California Coastal Commission.
All the above being said, Plamen Petrov, P.E. shall be considered a qualified preparer for
the Bulkhead Conditions Report on this project.
OBSERVATION
A cursory observation of the existing seawall/bulkhead was conducted by a representative
of our office on July 16, 2021. Observed was the visible/exposed portion of the waterfront face of
the seawall. Due to the site conditions, tie-backs were not accessible, thus not observed.
FINDINGS
The pre-cast jetted-in concrete panels and cast-in-place concrete coping of the seawall were
found in generally good condition, without noticeable evidence of distress. Some minor cracks
were observed, which is a typical condition for many of the seawalls of this vintage in the area.

CONCLUSION
Based on our site observation, we conclude that the existing seawall is required to protect
the proposed principal structure on the lot. To be able to do so, the seawall shall be
repaired/reinforced/raised as reflected on the enclosed Drawings SW-0 thru SW-2. As reflected on
section K/SW-2, new concrete deck replacing the existing cantilevered concrete deck will be
constructed and firmly attached to the top of the existing seawall. New concrete stem wall will be
constructed along the bayward edge of the deck, with top of wall elevation of +10.9’NAVD88 and
adaptability to be raised to +14.4’NAVD88 in the future, if deemed necessary. New tie-backs and
deadmen will be installed as well. The coping and panels of the existing seawall will remain
unchanged. Once the seawall is reinforced in accordance with the enclosed drawings, no repair or
replacement of the seawall shall be anticipated in the next 75. If during this period though, the
seawall displays any sign of distress that requires immediate attention, it should be repaired or
replaced at that time accordingly, without seaward encroachment from its current location.
The above conclusion was prepared based on the existing conditions, proposed drawings,
and within the inherent limitations of this study, in accordance with generally acceptable
engineering principles and practices. We make no further warranty, either expressed or implied.
PMA Consulting, Inc. appreciates the opportunity to work with you towards the successful
completion of your project. Should you have any questions regarding this report, please give us a
call.
Respectfully submitted,
Plamen Petrov, P.E.
