SAN FRANCISCO (KCBS)— San Francisco Supervisor Scott Wiener has asked the city’s transportation authority for an audit on the public transit impacts of a new Golden State Warriors arena proposed to go along the waterfront.

Wiener reportedly sent a letter to the San Francisco County Transportation Authority on Monday. Part of the issue is who would foot the bill for most of the transportation costs.

The Warriors hope to build the new arena along the Embarcadero that would also be a major concert venue. Wiener said he wants the impact report before any further decisions are made.

“This is going to bring an enormous number of people into that part of the waterfront and people are going to need good public transit or we’re going to have a traffic nightmare,” Wiener said.

He added that doing a large development like this would include having to pay transit impact fees and he wants the Warriors to be part of the solution in helping that system function.

The new arena would hold 18,000 people and the project would also include a hotel, a parking garage, retail shops and a residential high rise.
