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 cast-in-place concrete section of the seawall was 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. 1PA2022-001 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. 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.
