RE: BULKHEAD CONDITIONS REPORT FOR COASTAL DEVELOPMENT
PERMIT
Mr. Jeff Logan; Applicant
2286 Channel Road
City of Newport Beach, County of Orange
WSA Job #7543
Dear Mr. Logan,
William Simpson & Associates, Inc., (WSA) 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
Masoud Jafari, S.E., the preparer of this report, holding a Bachelor of Science Degree in
Structural Engineering from Tehran, Iran, is a Licensed Civil Engineer - Certificate No. C43673 -
and Structural Engineer - Certificate No. S3812 - by the State of California. He joined the
company in 1987 and is now partly the owner, serving as the principal in charge of the company.
He has been actively involved in the design and entitlement of waterfront developments such as
custom homes, seawalls, piers, platforms, floating docks and marinas for over 30 years.
All the above being said, Masoud Jafari, S.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 October 8, 2020. 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 cast-in-place concrete seawall was found in generally good condition, without
noticeable evidence of distress. Some minor horizontal and diagonal cracks were observed, which
is a typical condition all 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 as reflected on the enclosed Drawings SW-1 and SW-2. 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.
William Simpson & Associates, 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,
Masoud Jafari, S.E.
