Several Los Angeles trucking companies have filed suit against the city and the Los Angeles Harbor Commission for forcing them off land they own to build a railyard near the Port of Los Angeles.

One suit was filed by Fast Lane Transportation and the other coming from California Cartage, Three Rivers Trucking, Los Angeles Grain Terminal and San Pedro Forklift, according to Courthouse News Service.

They are challenging the approval last month given by the city to Burlington Northern Santa Fe Railway’s environmental review and a permit it was awarded to build a $500 million, 153-acre railyard about four miles from the port. The Southern California International Gateway project will move cargo in and out of the port by rail, rather than truck, in attempt to reduce traffic congestion and pollution in the area.

The trucking operations claim the city violated the California Environmental Quality Act by failing to consider the "effects of transportation, land use and jobs, among other impacts, the project has on the petitioners and the community.” They also say a thousand jobs will be lost through their forced relocation under eminent domain.

The lawsuits have been filed in Los Angeles County Superior Court.
