Button. Click to sign up for email updates 




The City of Portland’s Bureau of Environmental Services is continuing our work to repair and replace critical sewer and stormwater infrastructure. Environmental Services will continue to provide information and updates on construction schedules and activities during the COVID-19 emergency. 

Updated January 7, 2021

Environmental Services continues construction of the Montavilla North Sewer Repair Project in the Montavilla Neighborhood (north of Stark Street). The project includes replacing or repairing more than three miles of deteriorating 100-year-old public sewer pipes, 87 manholes, and public sewer connections for 221 properties. These improvements will help protect the public and our environment by reducing the possibility of sewage releases to homes, businesses, and streets.

For information about the sewer improvements in the Hollywood-Grant Park neighborhoods that are included in this project, visit
