Balboa Marina, known as one of Newport Beach’s finest marinas, embarked on an improvement and expansion project adding 25% more private slips and establishing a new public dock in a prime Newport Beach location.
Apart from the installation of new docks and utilities, the project necessitated the demolition and replacement of an existing seawall, including 36 deep soil mixing columns and 2 king piles for footing support. Power was contracted to perform the work after an internal referral by project stakeholders at Bair Island Marina, where Power had successfully executed seawall and marina upgrades the year prior.
The project's location posed a distinctive challenge given its close proximity to residential areas. To address this issue and minimize noise disturbance, the construction schedule was adjusted. The approach involved restricting impact pile driving activities to a single day each week. To maintain project momentum without causing delays, a jetting technique was employed. Jetting allowed piles to be driven into the sand quietly, to a substantial depth of 5 feet to tip elevation. These piles could then remain plumb until the designated day when the driving process resumed, taking them to their intended depth.
The project's timeline was strategically set to ensure that the marina would be expanded and fully functional in time for the 115th annual Newport Beach Christmas Boat Parade, resulting in a joyful and memorable holiday event for everyone.
