Amazon Web Services Confirms $264 Million West Richland Ranch Purchase for Data Center Campus

Amazon Web Services confirmed it is the buyer behind a $264 million purchase of nearly 1,000 acres at West Richland's Lewis & Clark Ranch in Washington state, where it plans a data center campus with up to 21 buildings. Yahoo reported the confirmation, which AWS gave in a phone call on Monday.

Trammell Crow's Ranch Purchase and AWS's Plans

Trammell Crow Co., a Dallas, Texas, real estate firm with a data center development business, purchased nearly 1,000 acres from the estate of the late agriculture icon Frank Tiegs in July. AWS said such arrangements are standard. Amazon Web Services is the cloud computing division of Amazon.com, providing on-demand compute, storage, AI/ML and platform services across 39 regions and 123 Availability Zones.

An AWS spokeswoman said the company plans to build three buildings in the first phase, and the site could grow to as many as 21 data center buildings. AWS has not yet submitted a site plan to the city of West Richland, and the project is subject to scrutiny under the Washington State Environmental Policy Act, or SEPA.

AWS will hold a public open house from 5-8 p.m. on November 19 in the cafeteria of Enterprise Middle School in West Richland, at 5200 Paradise Way. The "science fair" style event will share details about the future campus along Ruppert Road and give participants a chance to discuss concerns with staff.

What AWS Says About Water, Power and Taxes

According to akta.pro company records, AWS has announced $200 billion in 2026 AI infrastructure investment across 39 regions and 123 availability zones, and plans for 7 more availability zones and 2 more regions in the Kingdom of Saudi Arabia and Chile. The same records list more than 1,000,000 active customers every month.

In its FAQs, AWS said it will use outside air to cool the facility 93% of the time and secure a surface water supply for the estimated 10 million gallons per year it needs for the first three buildings, rising to 70 million gallons at 21 buildings. AWS said its operations will not affect drinking water or local wells. The AWS parcels paid about $6,400 in property taxes in 2026, according to AWS, which described the eventual bill as "millions."

Earlier AWS Land Deals in Washington

In 2024, AWS used the alias "Advance Phase LLC" to make a deal for more than 500 acres at Wallula Gap Business Park, about 10 miles southeast of Pasco, for a proposed $5 billion data center campus, Yahoo reported. Its identity was not officially confirmed until the Port of Walla Walla closed the transaction in February.

At a recent West Richland City Council meeting, residents pleaded with elected leaders to consider their interests, and Tri-Cities Data Center Watch presented a petition calling for a temporary moratorium on data centers. The advocacy group notes West Richland planners were in contact with Trammell Crow as early as 2024, and the news became public in 2025 when then-Mayor Brent Gerry disclosed it during a Port of Benton Commission meeting.

Moratorium Vote Set for November 3

The West Richland City Council will consider an interim version of a moratorium when it meets at 6 p.m. on November 3.
