The record, newest first

  1. A Hermiston planning staff report, comparing parking at other Amazon sites, listed Westland at about 100 spaces for three buildings. (City of Hermiston Planning Commission, July 12, 2023)

  2. All three county commissioners approved the zone change after a hearing where no one testified against it; 1000 Friends of Oregon had sent a letter questioning industrial use of the land. (East Oregonian, April 14, 2017)

  3. The county planning commission heard Vadata's request to move about 120 acres from Exclusive Farm Use to Light Industrial with a limited use overlay and voted 7-1 to recommend it; the vice chair, the one no vote, objected to losing farmland. (Northeast Oregon Now, undated; Hermiston Herald, March 29, 2017; The Spokesman-Review (Associated Press), March 20, 2017)

  4. Trade press reported Vadata had signed a letter of intent to use the regional water system and had agreed to pay for needed improvements. (Data Center Knowledge, March 21, 2017)

Conflicts and open questions

  • The Hermiston report says Westland but gives no address; it is matched to the 2017 rezoning site by the shared Westland name and location.
  • The map point is approximate, from the reported location southwest of Hermiston near the Hermiston Generating Plant.
