Branchbox Breakwater Design at Pickleweed Trail, Martinez, CA, Section 227 Demonstration Project
Abstract
The objective of this Coastal and Hydraulics Engineering Technical Note (CHETN) is to provide a preliminary design of the branchbox breakwater for the Martinez project site in the National Shoreline Erosion Control Development and Demonstration Program (Section 227) using existing design guidance and lessons learned from previous branchbox breakwater projects. The branchbox breakwater system proposed herein derives stability from both the breakwater and wetland plants between the breakwater and the shoreline. Selection of the type of wetland plants to use behind breakwaters is a critical part of bioengineering batik protection. While this technical note provides some information on plants used at specific projects, the focus of this report is on the design of the breakwater part of the system. The city of Martinez is located in northern California's Contra Costa County, between San Pablo Bay and Suisun Bay. Pickleweed Trail is located within the Martinez Regional Shoreline Park in Martinez (Figure 1). The project area extends approximately 1,000 mi along the southern shore off Carquinez Strait, adjacent to the Union Pacific Railroad right-of-way. Sandwiched between the strait and the main line of the railroad, this recreational hiking trail is maintenance by the East Bay Regional Park District. The site, which is within the U.S. Military Engineer District, San Francisco, includes a coastal wetland habitat for a variety of species.
