The Port of Long Beach, in cooperation with the Port of Los Angeles and the Corps of Engineers, has been working on the development of a Master Plan for the San Pedro Bay area. This Master Plan, nicknamed the "2020 Plan", is intended to project the Port's land and channel requirements through the year 2020. Any landfill expansion program would be implemented in phases throughout the life of the Master Plan. The initial phases of such a plan would greatly limit the ability of the Port to revise the future configuration of landfill phases, making it important for the Port to determine a final landfill configuration before implementing the early phases. In developing the 2020 Plan, the Port projected a need for approximately 2,600 acres of additional land. In attempting to turn this 2,600 acre figure into a landfill scheme, the controlling agencies had to take a number of factors into consideration, including (1) water quality and tidal circulation; (2) potential ship motion problems; (3) additional berths required for future development; (4) land and waterside transportation corridors required; (5) availability of dredge material for creating the land; (6) available areas for creating landfills; (7) efficiency of land usage in various configurations; (8) types of ships anticipated to use the new landfills; (9) types of terminals anticipated to be located on the new landfills. The Port of Long Beach developed two basic schemes which addressed the requirements listed above. In either case, the landfill configuration for the Port of Los Angeles remained the same. The first scheme (called the island scheme, Figure 1) had the advantage of more closely matching the proposed Port of Los Angeles development. Water quality and tidal circulation would be improved with this scheme. The second scheme (called the horseshoe scheme, Figure 2) created a channel on the Long Beach side which did not match the orientation of the channel on the Los Angeles side. This channel was better protected from wave forces than the island scheme, where ships would have to be berthed along the exposed southerly boundary.

The San Pedro Bay Ports of Long Beach and Los Angeles continue to provide vital rail connections to the rest of the country. The Rail Enhancement Program sets forth the rail improvements necessary to maintain performance as cargo volumes grow through the year 2035. Implementation of the Rail Enhancement Program has faced hurdles including environmental permitting, funding and competing stakeholder concerns. Cargo growth eased in the years approaching 2010, but the timing of proposed improvements to the rail infrastructure remains critical and challenging. The Rail Enhancement Program is the result of work over the past ten years. Conditions affecting the program have continued to change since the original Rail Master Planning Study of 2000. Updates to the Master Plan have been performed in 2005 and 2010. These documents provide analyses and recommendations for rail improvements to maintain adequate rail service on the Alameda Corridor and through the Port to its rail yards. In developing the Rail Enhancement Program, simulation is used to understand the impacts of increasing cargo volumes on the rail system and to investigate infrastructure and operating improvements required to address deficiencies and to determine improvements to efficiently handle projected traffic. This paper describes the development process with a summary of the analysis methods, resulting proposed rail projects, implementation process and current status of implementation. The steps of the rail system development process include the following: • Evaluation of existing and proposed rail operations; • Conceptual design of over forty potential rail improvement projects; • Analysis of the capacity of existing and proposed facilities; • Scheduling of project development to meet demand; • Estimation of environmental, community and regional impacts and benefits; • Determination of schedule including environmental permit requirements; • Development of project funding plans; and • Preparation of engineering designs and construction documents. The paper will conclude with a summary of the status of key projects from the Rail Enhancement Program. Implementation of the Rail Enhancement Program has included permitting, funding and design efforts on individual projects. The projects currently under development total $1B out of the overall $2B program. The Rail Enhancement Program provides significant benefits to operating efficiencies, environmental impacts and economic impacts. Implementation has been a challenging effort and illustrates the myriad obstacles facing public infrastructure development.
