This fall, Environmental Services will install a valve and underground vault near the intersection of SE 3rd Avenue and Alder Street to reduce the rare build-up of air pressure in the public sewer system that can occur during intense rainstorms. The valve will help to ensure the sewer system operates safely and efficiently.
The project is located near the busy intersection of SE 3rd and Alder. Construction is anticipated to take up to four weeks and occur between October and December 2016. This includes time to set up, install piping and structures, and then restore pavement disturbed during construction.
Crews will work at the manhole in the street and install piping that connects to a new underground pressure valve and vault structure. There will be temporary traffic restrictions, such as reduced lanes or assistance from flaggers. Parking will be temporarily removed around the work area during construction. Environmental Services is designing the project now. More detailed information will be available this summer.
In the coming weeks, we will visit businesses nearest to the project area to discuss their needs during construction (e.g., delivery and access). At the time of the visit, we will provide a questionnaire that helps us know more about business operations and activities in the area as we prepare for construction. If we haven’t dropped by your location this spring and you’d like to talk with us, please contact us to schedule a visit. Thank you for your cooperation during this important sewer project.
If you have questions, comments or concerns about business operations, disability issues or medical or business deliveries, please contact Cheryl Kuck by phone at 503-823-7898 or by email. In your email and voicemail messages, please provide your property address and the project name (Alder Shaft).
To sign up for periodic email updates, email Cheryl with “Alder Shaft” in the subject line. If you provide your address, we can provide you with specific construction information about your location.
Environmental Services maintains and improves the City’s sewer infrastructure. The SE Alder Pump Station Upgrade Project will improve reliability, increase pumping capacity and help prevent sewage releases to protect public health, water quality and the environment. For more information about that construction scheduled to begin late fall 2016, visit www.portlandoregon.gov/bes/AlderPS.
Environmental Services is also planning repairs to an aging sewer line in poor condition along SE 3rd Avenue south of SE Alder Street. Construction is planned for 2017 or 2018. For more information about that location, visit www.portlandoregon.gov/bes/citywide.
