Meanwhile, new estimates added a wrinkle to the price of the proposed LA streetcar. Proponents believed the streetcar would cost around $125 million, to which Downtown LA residents voted in favor of levying a tax that would yield $62.5 million towards construction. The difference would be covered by federal grants. However, utility relocation estimates could add as much as $166 million to the price tag, and that doesn’t include hidden utilities that can pose problems during construction. This will likely delay the application for federal grants and, hence, the opening of the streetcar itself. However, proponents expect that engineering efficiencies can be found during the design process, even as streetcar supporters seek additional federal funding.
