Pickleweed Trail, Martinez, California
Section 227 Demonstration Site

Active Project
Wetland substrate eroded by tidal currents and wave action, Pickleweed Trail, Martinez, California.
Wetland substrate eroded by tidal currents and wave action, Pickleweed Trail, Martinez, California.
Enlarge: 460x345(36kb)
The shoreline here is experiencing severe erosion due to the combined effects of wind waves and vessel wakes. The project goal is to test the effectiveness of a bioengineered “branch box” structure similar to those used in Europe, at accumulating marsh substrate and reducing wave-induced erosion in an estuarine environment.

Section 227 Demonstration Sites Sites at which the program methods have been implemented.
Allegan County, Michigan (Section 227 Demonstration Site) - Groundwater adds weight to the soil, disrupts the soil skeleton, and exerts upward seepage pressure on the soil particles and reduces contact among them if the soil becomes saturated and pore pressure is high.
Alligator Point, Florida (Section 227 Demonstration Site) - Alligator Point is subject to continuous and severe erosion due to storm induced wave attack, and local interests desire emergency assistance to protect the shoreline and adjacent Highway 370.
Cape Lookout State Park, Oregon (Section 227 Demonstration Site) - Dynamic revetments appear to offer an alternative method of shoreline erosion control that provides a natural-looking solution without any hardened structures.
Cape May Point, New Jersey (Section 227 Demonstration Site) - Cape May Point is particularly vulnerable to storm damage due to exposure to waves from both the Atlantic Ocean and the Delaware Bay.
Chesapeake Bay Breakwaters, Maryland and Virginia (Section 227 Demonstration Site) - The long-term goal of this project is to document breakwater system performance around the Chesapeake Bay and develop design guidelines for breakwaters in cohesive, sand-limited, and fetch-limited systems.
Jefferson County, Texas (Section 227 Demonstration Site) - Storms erode the thin layer of sand, exposing the mud to further erosion. During storms, beach sediment is washed over the low-laying dune and deposited in a wetland area landward of the beach.
Miami Beach, Florida (Section 227 Demonstration Site) - The primary objective of the demonstration project will be to hold the maintain template dimensions between renourishment in an innovative or non-traditional manner.
Oil Piers, Ventura County, California (Section 227 Demonstration Site) - Oil Piers is located in northern Ventura County along Highway 101. The beach is backed by a rock revetment and highway embankment.
Pickleweed Trail, Martinez, California (Section 227 Demonstration Site) - This project is considered an optional site for development in the Section 227 Program. The project is will be developed pending allocation of sufficient Program resources.
River Street Cut, Seabrook, New Hampshire (Section 227 Demonstration Site) - The Blackwater River is changing course resulting in localized bank and bar erosion and channel and harbor shoaling.
Sacred Falls Beach Park Hauula, Hawaii (Section 227 Demonstration Site) - The low-elevation coastal road that services the area is poorly protected with randomly placed boulders and waste concrete piles.
Sheldon Marsh, Huron, Ohio (Section 227 Demonstration Site) - A 1.8 km-long barrier beach and wetland preserve located at the southwest end of the 10.5 km-long Cedar Point sand spit in Huron, Ohio.
