The disclosure and our analysis

What the filing reveals

Digital Beaver 4 LLC proposes 144 MW of data storage and processing capacity at the Corny Data Center campus in Hillsboro, Oregon. The 92-page joint permit application, received by the Oregon Department of State Lands on October 6, 2026, identifies hyperscale and enterprise colocation as the intended uses. The application narrative and a signed city support letter connect the proposal to Digital Realty. [Sources 1 and 2]

The campus would sit east of NE Cornelius Pass Road and north of NE Cornell Road. Washington County identifies the property as the 28.95-acre Wishing Well Lot 2, parcel 1N226D000200. Its sales record shows a March 10, 2026 transfer from Legacy Health Systems to Digital Beaver 4 LLC for $50 million. That is a recorded land acquisition price, not a construction budget. [Source 3]

Two buildings and a road extension

The packet describes two buildings, each two stories, with generator and electrical equipment yards, campus circulation and stormwater facilities. The site plan places a stormwater facility toward the southeast. The proposal would extend NE Ronler Drive along the northern boundary toward NE Aloclek Drive. Its narrative describes a three-lane collector, an 80-foot improved right-of-way and two campus access points. [Source 1, pages 2, 10, 27 and 31]

The applicant projects 186 full-time employment opportunities. AKS Engineering & Forestry prepared the application. A November 3, 2025 letter signed by Hillsboro Economic Development Manager Valerie Okada supports Digital Realty’s wetland application. The letter documents city economic-development support; it is separate from a land-use approval. [Source 1, pages 5 and 33]

Wetlands remain part of the approval process

The applicant proposes 17,075 square feet, or 0.39 acre, of permanent wetland impact. The packet specifies 315 cubic yards of excavation and 6,830 cubic yards of structural fill, with 0.39 mitigation credit proposed from Dairy Creek Mitigation Bank. These are requested impacts and mitigation measures. The state application record displays Application awaiting fees and does not establish an issued removal-fill permit. [Sources 1 and 2]

How it connects to Hillsboro’s Q3 filings

Corny’s city Development Review II application, DR26-0031, was filed July 21, 2026. The state packet’s signed planning affidavit explicitly identifies that city case. Corny and the separate Wagon proposal entered the city process six days before Hillsboro adopted its 120-day application moratorium on July 27. The city said previously submitted applications could continue through review. [Sources 1, 4 and 5]

The October 6 state application supplies additional detail about the July proposal. Its filing date falls after the September 30 end of Q3. The proposed 144 MW is a post-quarter project disclosure, with the city application date kept separate.

What 144 MW means for the market

Our analysis: the disclosure gives buyers a clearer measure of Corny’s proposed scale. It does not establish when that capacity could be delivered. The next useful evidence would be an approved land-use decision, utility-service documentation and a construction schedule tied to those approvals.

What remains unknown

The reviewed records do not establish contracted utility capacity, an energization date, a tenant, construction cost, available inventory, cooling-water demand or generator count and ratings. The narrative references approximately 371,000 square feet of building space, but does not clearly reconcile that figure with the two-story layout; verified gross floor area remains unresolved. The state packet is not a complete substitute for the city’s architectural, traffic and noise submissions.
