Historic Resource Inventory (HRI)
This map shows properties in the Portland area that were surveyed as part of the 1984 Historic Resource Inventory (HRI). Many of the mapped properties have been designated as historic landmarks and/or are included in historic districts. Those designations are not shown here. The HRI data is being tested in this format, and the original inventory records have been abbreviated. More complete data on each property is available on this website. Note there may be some inconsistencies between the digital files and the original inventory records. This data is therefore provided "as-is."
