The expansion area must be designated Heavy Industrial (M-2) with a Hyperscale Data Center overlay, reserving the land for hyperscale data centers and supporting uses rather than unrestricted industrial development.

HDC sites must generally provide at least 100 suitable acres, be outside the 100-year floodplain, have slopes of 5% or less, and have sufficient size and configuration for large buildings, access, utilities, and substations.

HDC structures must be set back at least 200 feet from residential land to reduce noise and other impacts.

The measure requires annexation before the city provides ordinary urban water and sewer services; property owners or successors must pay for service extensions and identified off-site intersection improvements.

Development is subject to transportation improvements identified for the area, including upgrades or widening at Feedville Road intersections, access-management changes at the U.S. 395 intersections, and improvements bringing Feedville Road up to urban standards.

The ordinance does not become effective until 30 days after Umatilla County co-adopts the map amendments, creating a waiting period before the amendments take effect.

Expands Hermiston’s Urban Growth Boundary by approximately 810 acres, adding land south of E. Feedville Road, north of the Feed Canal, and between S. Ott Road and Oregon Highway 207 for urban development. expanding the Urban Growth Boundary to include approximately 810 acres

Creates a Hyperscale Data Center overlay in the city code, providing a zoning category specifically intended for hyperscale data centers and related development. [A new section 157.058 (Hyperscale Data Center (HDC) Overlay)](https://ecode360.com/HE4477/laws/LF2658811.pdf#:~:text=A%20new%20section%20157.058%20(Hyperscale%20Data%20Center%20(HDC)%20Overlay))

Reserves the expansion area for hyperscale data centers and supporting uses by requiring the HDC overlay and M-2/HDC zoning, rather than leaving the land available for unrelated urban uses. ensure that land added to the UGB is reserved for HDCs and supporting uses

Provides protection against rezoning away from the intended industrial use by applying the Oregon UGB rule that land added for a particular industrial use must remain planned and zoned for that use unless it is removed from the UGB. must remain planned and zoned for that use unless the city removes the land from the UGB

Adopts a Public Facilities Plan for the existing and expanded urban growth area, including planned water, wastewater, stormwater, and transportation facilities to serve the data-center sites. the city can provide urban services efficiently

Allows municipal water and sewer extensions to serve the expansion area after inclusion in the UGB and annexation, with planned facilities shown for the HDC sites. will be provided with municipal sewer and water services

Allows the city to provide water for industrial lands under Hermiston’s existing policy framework, including industrial lands within the UGB and certain exception-area industrial lands, subject to specified service and annexation conditions. Will extend public water supply only to

Supports transportation access through planned improvements to Feedville Road and nearby intersections, including intersection upgrades, widening, traffic-control changes, turning restrictions, and indirect U-turn accommodations. identified transportation improvements

Permits annexation based on written consent from all private property owners in the proposed annexation area, allowing the city to use the consent-based annexation process rather than requiring an election when the statutory conditions are met. petition signed by the owners of all private tracts
