Dec. 22 Update: the following news release updates the Dec. 20 notice of a sinkhole opening up on SE 49th Ave between Rhone and Bush streets:
Sinkhole-related repairs at SE 49th Ave. extended to Friday; sewer replacement project moved up from July to early January to address long term needs
(Dec. 22, 2016) - Environmental Services crews and a contractor working on a sinkhole repair at SE 49th Avenue just south of Powell Blvd finished replacing a damaged section of 97-year-old sewer pipe today and filled in the 16-foot deep sinkhole that opened up two days ago. They also found another deteriorated section 15 feet north of the sinkhole and are extending the temporary repair project through Friday.
Local access will be maintained and sewer service continues to all homes in the area.
In addition, BES is moving up a planned sewer replacement project for that area from July to early January to create a long term solution. The street had been slated for sewer pipe replacement in July as part of the Powell Sewer Repair Project, a multi-block capital project that began in May and is expected to finish in November 2017 to repair and replace aging public sewer pipe in Southeast Portland. The area’s pipes are between 60 and 104 years old. The new system will also add capacity, replacing eight-inch diameter pipes with sections that are 18-inch to 24-inches in diameter. The larger pipes will dramatically reduce the chance of basement backups and overflows into the street that can occur during heavy rains.
The two-block section of SE 49th Avenue between Powell Boulevard and Bush Street is expected to reopen to the public on Friday. It will remain open through early January when crews will return to replace the eight-inch pipes with 18-inch to 24-inch diameter sections. That work is projected to last for up to eight weeks.
