The Pier A Zero Emissions Infrastructure Project involves electrical improvements and the construction of cargo-handling lots with electric vehicle charging stations at the SSA Marine Terminal at Pier A in the Port of Long Beach, with a total of 166 electric vehicle charging stations and foundations consisting of 56 Level 2 single- and dual- dispenser electric vehicle chargers, 104 Level 3 dual-dispenser electric vehicle chargers, and 6 light-duty forklift chargers to support the deployment of human-operated, zero-emission electric cargo-handling utility tractor rigs, top handlers, forklifts, electric rubber-tired gantry (eRTG) cranes, and on-terminal vehicles used in cargo operations, administrative functions, security and maintenance activities. To accommodate the new cargo-handling equipment lots, an existing longshore labor parking lot at the marine terminal will also be relocated adjacent to the its current location.
The project involves the establishment of lots for the electric charging cargo-handling equipment and on-terminal vehicles: (1) Top Handler Lot, (2) Utility Tractor Rig (UTR) Southern Lot, (3) North Cargo-Handling Equipment (CHE) Lot; and (4) On-Terminal Lot. In addition, lanes for the operation of eRTGs will be created on the marine terminal. Electrical improvements at the project site include installation of primary and secondary unit substations, a new electrical distribution system with medium and low voltage equipment dedicated to the new zero-emission cargo-handling equipment and on-terminal vehicles, new duct banks, new load interrupter switches, utility access holes, and pull boxes. At the project site, approximately 20,000 linear feet of soil will be trenched and backfilled to accommodate electrical, water, and storm drain utility improvements and a total of approximately 60,000 square yards of pavement will be added to the project site. Construction of the project is expected to take approximately 28 months.
The Top Handler Lot will accommodate 34 top handlers, with a one-charger per top handler configuration. A 600-linear-feet, 8-feet tall security chain-link fence will be installed to separate the terminal from the labor parking lot. Five pedestrian security turnstiles will provide controlled worker access between the two areas; three turnstiles will be installed near the south end of the Top Handler Lot, between the Top Handler and UTR lots; two additional turnstiles will be installed at the north end of the lot. An Americans with Disability (ADA)-compliant pedestrian swing gate will also be installed. A 3-feet wide walkway will be installed around each top handler, extending from the base of the operators access stairs to the main pedestrian pathway; striping will delineate the walkways. One fire hydrant will be installed in the Top Handler Lot in accordance with City of Long Beach Fire Code.
The UTR Southern Lot will support up to 106 UTRs and three heavy-duty forklifts. The electric charging stations in the UTR Southern Lot will be configured with dual cables to serve, two adjacent UTR stalls and heavy-duty forklifts. The stationary charging system for the UTR Southern Lot will be powered from six sets of secondary unit substations. A continuous 3-feet wide walkway will be striped around each UTR and heavy-duty forklift. New ingress and egress points will be installed at the north and south ends of the parking lot, all drive aisles will be configured to support two-way traffic into the UTR Southern Lot. Each UTR parking space will include wheel stops and bollards, and reinforced concrete traffic barriers (K-Rail) to define drive aisles throughout the lot to protect the charging equipment and adjacent pedestrian walkways, electrical equipment. A 625-linear-feet long, 8-feet high security chain link fence will be installed at the UTR Southern Lot; a 16-feet wide manual chain link slide gate will be installed near the center of the lot for emergency fire department access between the Labor Parking Lot and the marine terminal.
The North CHE Lot will support electric charging in 14 UTR stalls and 10 non-charging UTR stalls, 2 heavy-duty forklift charging stalls, and 3 top handler charging stalls. The charging station in in North CHE Lot will be configures with dual cables and paired with a cable management system to serve two adjacent stalls. The stationary charging system will be powered from a secondary unit substation. A continuous 3-feet wide walkway will be striped around each UTR and heavy-duty forklift to maintain clear pedestrian circulation. Drive aisles will be configured to support two-way traffic and equipment movement.
The On-Terminal Lot will accommodate a total of 62 parking spaces for vehicles used in marine terminal operations, including administration, maintenance, crane maintenance, roadability, security, and rail. Electric Vehicle Supply Equipment (EVSE) will support the light-duty and medium-duty on-terminal vehicles. Where feasible, existing electrical service capacity from nearby building will be used to supply the new charging equipment in the On-Terminal Lot. One opportunity charger will in located at the terminals maintenance building and one at the administration building. A 3-to-1 vehicle to dispenser ratio is expected for the marine operations, administration, maintenance, and roadability areas; a 2-to-1 ratio is estimated for the security, rail, crane maintenance, and gearman office areas. Bollards and K-Rail will be placed as needed to safeguard equipment, protect pedestrian walkways and define vehicle circulation paths.
The new eRTG lanes are anticipated to support up to 14 grid tied eRTGs, with the supporting transformer and switchgears located near the adjacent Top Handler Lot. K-Rail with integrated chain-link fencing will be installed along the eRTG lanes to restrict vehicle and pedestrian movements and protect the cabling that provides power to the eRTGs. A cable protection system will be installed to safeguard medium-voltage cables while allowing equipment to traverse the lanes without damaging conductors. Bollards will be installed to protect electrical distribution equipment.
The existing longshore labor parking lot will be relocated westward from and adjacent to its current location at the marine terminal. The new longshore labor parking lot will accommodate 255 parking spaces compared to the 250 parking spaces in the former parking lot. Parking stalls will comply with the City of Long Beach Municipal Code and will also meet applicable California Green Building Code (Title 24, Part 11) (CalGreen) parking lot requirements, including provisions for electric vehicle infrastructure, grading, and sustainable site development. In addition, minor modifications to the existing grades and storm drain systems would be performed, with the installation of new drainage inlets at the sump stations to collect stormwater runoff, routed to stormwater best management practices (BMPs) for treatments and subsequent discharge to the existing storm drain. A gravel area in the north portion of the labor parking lot will also collect surface runoff shore the adjacent North CHE Lot.
