The new South Portland addressing section was approved by the Portland City Council on June 6, 2018 and is bounded by SW Naito Parkway SW View Point Terrace and Tryon Creek State Natural Area to the west, SW Clay Street to the north and the Clackamas County line to the south. It includes the Lair Hill, Johns Landing and South Waterfront districts and Lewis & Clark College as well as the Riverdale area of unincorporated Multnomah County south of the Portland city limits. [https://efiles.portlandoregon.gov/Record/12011415/] In 2018, the city's Bureau of Transportation finalized a plan to transition this part of Portland into South Portland, beginning on May 1, 2020 to reduce confusion by 9-1-1 dispatchers and delivery services. With the addition of South Portland, all six addressing sectors (N, NE, NW, S, SE and SW) are now officially known as sextants.
