The Newport Beach Marina Park project involved construction of a new community center, sailing center, park area, playgrounds, and marina in the vibrant Newport Beach community of the Balboa Peninsula. Dutra constructed Phase Two of the project which included construction of a new concrete bulkhead seawall, dredging of a boat basin, beach nourishment, stone column ground improvements and site improvements. The project was successfully delivered in a tight working window around other phases of the project.
Major challenges on the project included driving concrete sheet piles through a dense layer of sand, coordinating the installation of the grouted tiebacks through the bulkhead seawall and around the adjacent stone columns, and working in a highly visible area surrounded by neighborhood communities. Dutra partnered with the local stakeholders to limit pile driving hours and minimized noise pollution by using a shroud around the hammer. Additionally, strict truck routes were used to transport dredged sand to nearby beaches to minimize traffic congestion in the community.
