The company Prologis is eyeing a new location at 5977 Silver Creek Valley Road to be the site of a major new data center development. The San Jose location is currently vacant and well-situated for the project development, with access to nearby utilities and a local workforce experienced in data center construction and management.

If approved to move forward, the multi-level structure would include a total interior square footage of more than 500,000 square feet, making it a truly massive development. Of that square footage, at least 30,000 would be set aside for office space, with the rest being used to house equipment for processing and storing data.

The total expected energy requirements of the building is 99 megawatts. The site is well-positioned within three miles of an existing PG&E substation, and the developers plan to construct their own local substation on-site, along with backup generation to support the building’s energy needs. The site will also require a water supply equal to approximately 40 households. As per reporting from the Bay Area News Group, the developer has committed to minimizing the impact this project will have on the surrounding area.

The building itself is expected to have a simple exterior design. Early concept renderings show a blocky multi-story structure with a grey and white façade. The project focus will be functionality over aesthetics, but the developers are still making an effort to design landscaping and façade façade detailing to help break up the building’s chunky massing. Prologis has indicated that the project timeline is expected to be approximately two years.

    Who are you going to pay off to get this power and water guzzling monster built? This state can barely keep the lights on and we’re adding load to the grid with more electric everything. The water supply in So Cal is going to be limited by the lack of water in the Colorado River so water will need to come from us while you’re starting at the average usage for 40 households. I believe that is probably a bogus number. I hope the city council or whoever has oversight thinks long and hard before putting something like this in place.

  2. No thanks. Why no talk about the other 2 within a mile already. Ssj should not suffer the load, waste, and big ugly buildings to support this BS being jammed on us. Move on.

  3. PG&E just increased capacity at the substation near this proposal and plan to increase it again soon.

    Also, you guys know that we’ve had tons of data centers in SJ and the rest of SCC, right?

    Prologis are known (behind the scenes, of course) to be ruthless, cutthroat liars, who continue to glaze their destructive projects and push them through planning before any extensive review or community organizing can catch up.

    They operate with a “move fast and break things” mentality and hope no one analyzes anything.

    I’ve gathered irrefutable proof that they have falsified multiple CEQA EIR documents for another high profile project- understating health impacts by a factor of 4 or more, and outright concealing the location of a children’s day care across the street.

    The day care was a big threat, possibly a dealbreaker, but they neutralized it by

    What they did is not only illegal, it’s morally and ethically reprehensible. I won’t mention the specific environmental violations that have followed, as that seems to ensure my comments are censored by mods.

    One only need to search “Prologis ____” (fill in blank w/ banned toxic substance formerly used in bldg materials).

    Prologis is a despicable company run by greed and guile. People should start jumping off their ship now, because you will not want to be associated with them in the near future. Divest and dump their stock like the trash it is.

    The information that will be publicly released on them (post-litigation) will send them straight into the spotlight of “most-hated” corporations.

    They have been desperately trying to stay hidden, uphold the sustainable mask, and know it won’t last forever.

    Even their own sustainability reports completely omit NOx and SO2, the most significant emissions from logistics by far!

    Project Sail is another of theirs generating controversy, and using the fallacious “closed loop” cooling argument to dismiss concerns (those systems are full of additives and PFAS compounds, and do have to be emptied sometimes).

  5. This is just horrible. Even though I live in Milpitas everything you guys in San Jose do is going to affect us since we live so close. Please say no to this data center and make sure the elected officials of San Jose know that.
