Committee designates Transportation Authority as Treasure Island mobility manager

The Budget & Finance Committee voted to forward a resolution designating the San Francisco County Transportation Authority as the Treasure Island Mobility Management Agency (TIMMA), the body charged with implementing the Treasure Island Transportation Implementation Plan.

Bob Beck, Treasure Island director, explained the TIMMA concept was authorized by Assembly Bill 981 and refined in the 2011 Treasure Island Transportation Implementation Plan. He said TIMMA’s role would include preparing studies, adopting rules, administering island transportation revenues and using pricing tools such as parking fees and bridge tolls to discourage automobile use and support high-quality transit.

Beck described the development program on Treasure Island as anchored by approximately 8,000 residential units, 25 percent of which will be affordable; he also cited 100,000 square feet of office space and open-space improvements. Planned transportation measures include new ferry service to the Embarcadero, expanded Muni and AC Transit service, an on-island shuttle, unbundled parking, congestion pricing and mandatory transit passes for residents.

Supervisor Eric Marr asked about congestion management and whether tolls would be limited to peak hours or applied to arrivals, departures, residents or all vehicles; Beck said the Transportation Authority is modeling multiple parameters, including whether tolls should be collected on entry, exit or both and whether charges should apply only to island households or all vehicle access. He said the Authority will use its travel-demand modeling tools to study scenarios.

There was no public comment. The committee moved the resolution forward without objection.
