News Release
Advisory: sewage overflow from private system at SW 40th Avenue to tributary of Fanno Creek - 04/06/21

City crews yesterday responded to a sewage release from a privately-owned system at 7937 SW 40th Avenue, stopping the release and posting warning signs in the immediate area. 

This is the second release at this location this year. The cause is unknown. The City is contacting property management to make additional repairs and is further investigating these incidents.

In Monday’s incident, crews responded around 4:30 p.m. and stopped the release within the hour. They estimated about 25 gallons of sewage overflowed from a maintenance access hole on the property’s parking lot, through a private storm system and to a small creek that flows through a steep, forested edge of Gabriel Park and to Fanno Creek.

The public is advised to heed warning signs posted in the parking lot. Due to the possibility of elevated levels of bacteria in the water,  the public also is advised to avoid contact with the creek around and downstream of SW Multnomah Boulevard & SW 45th Avenue.
