Notes on the record

159-acre city-owned parcel at Hwy 237 & Zanker Road, North San Jose (bounded by Los Esteros Energy Center, Artesian Slough, Hwy 237, and the Silicon Valley Advanced Water Purification Center). Prologis selected as preferred developer by San Jose City Council (unanimous vote, Nov 18 2025) over Catellus-Deca and Trammell Crow proposals; CEQA review and ground-lease negotiation still pending as of source dates, not yet approved. 'STEM Park' = Sustainable Technology, Engineering and Manufacturing Park: four 99MW data-center buildings (1.68M sq ft total, capacityMw above) plus a separate ~785,000 sq ft / 100MW advanced-manufacturing component (not counted in capacityMw, different use). PG&E has committed initial 250MW via dual feed from the Los Esteros 230kV substation within 30-36 months. ~$25B investment widely reported (DCD et al.) but not confirmed directly by Prologis, omitted from investmentUsd. Projected 6,000+ jobs and $30M/yr city tax revenue are projections tied to a not-yet-approved project, not delivered counts, omitted from jobs numeric. A separate, already-tracked Prologis site (prologis-silver-creek-valley-san-jose-ca) and another new Prologis San Jose site (prologis-rue-ferrari-san-jose-ca, this same batch) are distinct parcels, not duplicates.

What the record does not establish, and the document that would

In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.

  • Cooling method and water use
  • Tax abatements or other public subsidy
  • Permanent jobs promised
Which document closes each gap
Cooling method and water use
The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
Tax abatements or other public subsidy
The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised
The economic development application or incentive agreement, which usually states a job commitment and a clawback.

Distances are between recorded coordinates, many of which are a city or county centroid, so treat them as approximate. Cumulative load on one utility and one aquifer is the question a planning commission rarely asks.
