Scanned Assessor tax maps of Clackamas County tax lots are available through a statewide program called ORMAP. ORMAP is administered by the Oregon State Department of Revenue. Clicking on the link below will transport you to their site. Please read the help section to better navigate the ORMAP site. Access to scanned tax lot maps can also be found using CMap.
Scanned tax maps are also available on CDs for purchase from the Clackamas County Assessor's Office. These images are more current than the images displayed on the ORMAP site. Contact the Assessor's Office at 503-655-8671 for details.
