LOL...zero chance that happens. Complete pie in the sky wishful thinking from a handful of folks with few resources.

[gillynova]

Damn.... at 700' too? That would make it the world's tallest ferris wheel. That sure is some wishful thinking and I think it would be a new amazing landmark in the Bay Area if it ever gets built.

Wow. This would be an amazing addition. I’ve always wondered why San Francisco didn’t have a ferries wheel. It seems like all major cities have one. I like how ambitious this group is by proposing the worlds largest ferries wheel. Back in the day San Francisco was always about breaking records, making things bigger and stronger, now we have become subtle. This brings us back to our roots and I hope it come to fruition.

First affordable homes break ground in Treasure Island redevelopment plan

The first segment of thousands of new homes planned as part of Treasure Island’s massive redevelopment effort broke ground on Friday.

Sixty-five of the 104 new units will be reserved for veterans currently experiencing homelessness, while the remaining units will house formerly homeless veterans. Construction is expected to wrap up in 2022.

The six-story, modular construction building is designed by Mithun and co-developed by the Chinatown Community Development Center and the Bay Area nonprofit Swords to Plowshares, which focuses on supporting veterans with social services including supportive housing and employment . . . .

Maceo May will feature a mix of studios, one-bedroom and two-bedroom units, and include a meal program and common open space that includes a forested “healing garden,” a playground and solar-powered community room.

Following on Maceo May, the next vertical construction will be four market rate rental communities, all of which include inclusionary BMR housing; they are set to break ground next year,” said Treasure Island Community Development spokesperson P.J. Johnston. “Treasure Island is getting closer to its promise of becoming one of the nation’s most socioeconomically diverse neighborhoods” . . . .

Concrete Starts Rising On Treasure Island In Regions Largest Residential Development
BY: ANDREW NELSON 5:30 AM ON APRIL 6, 2021

While sales for housing on Yerba Buena Island are underway, the first sign of concrete is finally visible on Treasure Island. The first of many buildings to come is rising at parcel C3.2, a 100% affordable housing development called the Maceo May Apartments. Its 105 units are a fraction of the largest master plan for residential construction in the Bay Area. The approximately 8,000-unit plan for the two islands is being developed by Treasure Island Community Development (TICD), a partnership with Stockbridge Capital Group, Wilson Meany, and Lennar Corporation.

The Maceo May Apartments is a $75 million six-story modular building. The structure spans 104,500 square feet for 105 units, ranging from studios to two-bedroom units for formerly homeless veterans and their families. The project will be delivered to the Chinatown Community Development Center and Swords to Plowshares, a Bay Area-based developer.

Mithun is responsible for the architecture. The facade will feature a sleek design with a white facade, and bronze-toned highlights sat on top of a recessed base with curtain wall and dark panels. The project is expected to be finished by 2022.







The property is opposite from C2.1, which is expecting a 345-foot mixed-use tower with design by Handel Architects. The building will produce 265 dwelling units and parking for 189 vehicles across 545,480 square feet.



The Maceo May Apartments is a part of phase one in construction, which has a combined 3,571 unit build-out, the largest of the four phases. Phase one will also introduce the adaptive reuse of existing buildings, 202,000 square feet of office, 67,000 square feet of retail, and 42,000 square feet of circulation space.

There will be 140,000 square feet of retail, 300 new hotel rooms, and 100,000 square feet of new offices for new buildings. 72.4 acres of public and open space will reshape what is currently the very inaccessible Yerba Buena Island. There will be 31.2 acres of open public space on Treasure Island.



The current approximate target to finish phase one is around 2026 to 2027, after existing residents move into new housing and ferry services begin in 2023. Bus services to Oakland and the East Bay will start in the summer of 2023, with MUNI services increasing by 2027.

Sweet! A little taste of South Beach to complement North Beach, although I guess there technically is already a South Beach in SF.

East Beach?

It would be nice if they could add to the waterline of Treasure Island using landfill to make it look more natural and less geometric.

I was working on Treasure Island in 1989 and saw the sand boils and water spouts. Frankly, I wouldn't want to live in any construction there. I suppose adding some natural contouring could be done to the shoreline but don't expect anything not strongly buttressed by rock to last long. Between the strong tides and liquifaction it'll disappear soon enough.

^Wow... I had no idea it had those kinds of issues... Yikes...

It not only had that but the utility lines travel in the causeway ramp down from the Bay Bridge and those all broke in 1989.

Treasure Island sinking into Bay

It's not going down as fast as the Titanic, but it's slipping into the Bay at a steady pace, according to a study for the San Francisco Redevelopment Agency. That raises the possibility that as much as half the island could be put off-limits to development when the Navy leaves in 1997.

At its creation in 1939 for the World's Fair, Treasure Island stood 14 feet above sea level; today it's at 9 feet, thanks, in part, to the 1989 Loma Prieta earthquake.

If another big quake hits, the 404-acre landfill may ooze into the Bay even faster, unless the crumbling dikes and levees surrounding the island are shored up or replaced before then. The scenario is outlined in a new seismic study of the island commissioned by the Redevelopment Agency.

"If there were an earthquake, there'd be lateral spreading - the island would move, split apart," said Larry Florin, director of project development for the Redevelopment Agency.

But with the right amount of money and engineering ingenuity, the island - or at least part of it - can be saved, city officials say. The estimated cost to fix up the island's riprap frame: $69 million to $500 million, depending on the extent of the work . . . .

"The real news out of this report is that we're considering stabilizing a smaller portion of the island," said Gloria Root, chairwoman of the Treasure Island Citizens Reuse Committee.

In the short run, she said, the dikes and levees could be strengthened to protect perhaps half the island. In the longer run, she said, when more money becomes available and the will is there, the rest could be shored up.

What isn't protected, she said, could be converted to parkland or other recreational uses that don't require buildings . . . .

During the Loma Prieta earthquake, the dikes and levees - a series of boulders and rocks intended to keep the Bay out and the landfill from drifting away - sustained significant damage.

Treasure Island, which had been slowly eroding even without the earth shaking, fell between 6 inches and 2 feet closer to sea level in 1989, depending on the location, Root said.

One assumes quite a bit of bolstering is being done as part of the construction now ongoing. I watched the Navy build a new medical clinic after 1989 and they "densified" the soil with tons and tons of rock. The new construction must involve pilings and bolstering the island perimeter. But Mother Nature has a way of winning these fights.

What isn't protected ... could be converted to parkland or other recreational uses that don't require buildings . . . .

just looking at the site plan, this seems to be what they are doing?

correct me if I'm wrong, but I heard that there were plans to build a Ferris wheel on treasure island that would be 700 feet tall and named the Golden Gate Flyer

I don't think they're moving forward with that anymore and instead, they built a temporary 150' tall ferris wheel in Golden Gate Park for their 150th anniversary. I believe it's staying there until 2023-2024?

Chron article about a test run of the ferry service to TI and the fact that things are to be going much more vertical come the new year.

I didn't realize the ferry terminal had been completed.

Wednesday, for the first time, city officials, and the reporters accompanying them, were given a preview of what the future might feel like for those willing to live in the 8,000 housing units slated to pop up on the 400-acre man-made island and former naval base between San Francisco and Oakland.

... the trip across the bay ... took only five minutes and 52 seconds.

Just before noon, about four dozen people, including Mayor London Breed, were whisked from the Ferry Building to the new $50 million terminal on Treasure Island. There they were given a tour of the two new housing complexes under construction, as well as the less sexy $600 million worth of infrastructure work that will make it possible for as many as 20,000 residents to eventually reside on the island.

There are bulldozers laying out streets and sidewalks and streetlights are going in. Three new water tanks, connected to water sources in both San Francisco and Oakland, hold 5.3 million cubic gallons. There is a new switchyard and wastewater treatment plant.



The first residents who will move into new Treasure Island housing will arrive next year.

January will bring the opening of the Bristol, a 124-condo complex that straddles a hillside on Yerba Buena Island, the steep, rocky outcropping that is connected to Treasure Island by a short causeway. Then in March, Chinatown Community Development Center and Swords to Plowshares will open Maceo May Apartments, a 104-unit affordable housing building that will largely be available to formerly homeless veterans.

Once that building is populated, the pace of development will accelerate rapidly, according to Chris Meany of Wilson Meany, the lead developer on the island. By spring, Meany’s group will start work on Tidal House, a mid-rise with 249 homes on the parcel closest to the ferry terminal. And the next affordable housing building, 138 units being built by Catholic Charities and Mercy Housing, will also be under construction.

Of the 10 parcels slated to be developed in the 1,800-unit, first phase of the project, eight of them are in the construction drawing phase and likely to be under construction in the next three years, Meany said.

Now that the vertical development has started, the whole 8,000-unit neighborhood — with a hotel and retail and parks — will explode “in a blink of an eye — if the blink of an eye is 10 to 15 years,” he said.

Meanwhile, the ferry is being tested and will start carrying the public in January. There will be 17 trips a day, and it will cost $5. For the first few years the ferry will be a 48-passenger aluminum boat specifically built for the bay that goes 40 mph. It will be operated by Prop SF. Once the service is established, the San Francisco Bay Area Water Emergency Transportation Authority will take over with 100-passenger ferries.
