Shoreline Restoration & Protection

OVERVIEW
Shoreline erosion has resulted in the gradual loss of sand and topsoil on the island’s shoreline. This erosion has undermined the island’s bridge abutment, road, and other infrastructure. Recent major storms such as Irene and Sandy have accelerated the shoreline loss. Langan has been involved with multiple phases of work to restore and protect the island’s bridge and shoreline areas. The first phase involved protecting the bridge abutment with a revetment scour blanket and the reconstruction of storm-damaged road pavement. The second phase of restoration included protecting the south shore with vegetated gabion walls and the shielding of radio transmission equipment on the north shore with gabion mattresses.

Pier 53 – Washington Avenue Green

OVERVIEW
Langan was retained to support the design-build improvements at Pier 53. The overarching goals of the project were threefold: ecologic enhancement, public access and community involvement, and balancing these priorities. The project sets a precedent for a larger program by serving as a template for ecological enhancements that will be effective for the adaptive reuse of industrial waterfronts. The ecological restoration will serve as a model for the proposed development of the entire 30-acre South Wetlands Park.

South San Francisco Ferry Terminal at Oyster Point

OVERVIEW
The South San Francisco Ferry Terminal at Oyster Point is the first terminal to be built south of San Francisco in generations. The 4,000-SF design-build project included vehicular access and parking with an extensive canopy over the bus waiting area, a pile-supported pier structure for embarking/disembarking, a waiting area, a gangway, and a floating dock with guide-piles and protective dolphins for vessel service. After analyzing the field and laboratory test results, Langan developed conclusions and recommendations for subsurface conditions, design parameters for vertical and lateral capacities of piles, estimated settlement, general site grading, evaluation of the dynamic stability of the adjacent shoreline slopes, flexible pavement sections, site seismicity and seismic hazards, and construction considerations.

Port of Redwood City

OVERVIEW
The Wharves 1 & 2 Replacement Project involved demolition of an existing timber wharf and construction of a concrete wharf in addition to civil engineering site improvements. The site is underlain primarily with soft to stiff clay (i.e. Bay Mud) such that long-term settlement impacts needed to be considered in time design solutions. The project includes phased demolition plans, erosion control, design-build site improvement plans, and permit acquisition of the active port as well as RCRA closure of the former Gibson Environmental facility. Grading was an important aspect of this project due to strict conformance to FEMA, sea level rise, and City Flood Plain Elevation regulations.
