Present Land Use
The project site (APN 841-69-039) is approximately 56 acres of undeveloped, open, flat land that has been designated for industrial uses by the General Plan and Zoning Ordinance for over 25 years. There is very little vegetation present at the project site, which includes sparse patches of grass, five trees, and some shrubs in the northeast corner. There is currently no paved point of access to the project site.
Document Description
Amazon Data Services (the applicant) proposes to build a data center (the project) at an undeveloped parcel located at the southeast end of Arroyo Circle in the City of Gilroy (the City). The project would support two data center buildings with a maximum electrical demand of 49 MW each and one security building totaling approximately 438,500 square feet. The project would also include the installation of two Battery Energy Storage Systems (BESS) to store energy in case of a power failure, a new electrical substation, and 27 backup generators, which include 25 Tier-2 emergency diesel-fired generators capable of supporting the maximum demand of 49 MW required for full operation of the Phase I servers, a 600 kW emergency generator for safety systems in the Phase I building and a 175kW backup generator for the security building. Backup generators will be equipped with a diesel particulate filter (DPF) verified by the California Air Resources Board (CARB) under Executive Order DE-07-001-08 to reduce emissions of diesel particulate matter by 85 percent or more. Phase II would utilize an emerging technology to provide backup energy in the event of a power failure. This emerging technology would be capable of supporting the maximum demand of 49 MW required for full operation of Phase II; while it is unlikely the emerging technology would emerge during the timeframe assumed for the purposes of CEQA analysis, analysts assumed an accelerated schedule in which Phase II would be constructed as soon as Phase I is finished to present a conservative analysis scenario regarding air quality and greenhouse gas emissions. Improvements to the property would include ancillary utility infrastructure for connection to existing stormwater, potable and recycled water pipelines, general site grading for stormwater drainage, and landscaping. The entire project site would be secured with an 8-foot high security fence constructed of tubular steel. Offsite utility improvements would include construction of a new recycled water pipeline to connect to the City of Gilroy’s Recycled Water System (in coordination with the Santa Clara Valley Water District and in accordance with South County Regional Wastewater Authority’s South County Recycled Water Master Plan Project), and PG&E’s installation of approximately 1,000 linear feet of new offsite overhead power lines to connect the new substation to the existing electrical distribution grid.
