PMA Job #19817
Dear Mr. Brandon,
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 19
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.
OBSERVATIONS
Cursory observations of the existing seawall/bulkhead were conducted by a representative
of our office on September 21, 2017 and October 13, 2017. Observed were the visible/exposed
portion of the waterfront face of the seawall, and one of the concrete buttress walls behind the
seawall.
FINDINGS
The cast-in-place concrete seawall was found in a good condition without noticeable
evidence of distress.
PA2017-239
CONCLUSION
Upon review of the available Architectural Drawings for the proposed development on the
site, we conclude that the existing seawall is required to protect the proposed principal structure.
To be able to do so, and to accommodate the proposed poll behind it, the seawall has to be
reinforced in accordance with the enclosed drawings SW-0, SW-1 & SW-2. Once the seawall
reinforcing in completed, no additional repair or replacement of the seawall shall be anticipated in
the next 75 to 100 years.
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.
