Final Stages of Designsurvey color markings and what they mean

The design team is currently working on finalizing the design.

Pre-Construction Activities

Over the next several months, crews will be locating utilities, surveying, inspecting sewer pipes and manholes with closed circuit TV, and drilling to take soil and pavement samples. These activities occur over time, rather than all at once, and will help engineers determine the appropriate construction method at each location.

Night Work

A noise variance is required when work occurs outside normal construction hours, 7:00 a.m. to 6:00 p.m. Monday - Saturday. This includes work after 6:00 p.m. and before 7:00 a.m., and all hours on Sunday.

This project has been granted a noise permit that allows night work at two locations:

The Portland Noise Office can be reached by mail at 1221 SW 4th Avenue, Portland, OR 97204 or at noise@portlandoregon.gov.

Please reference "Mt Scott-Arleta" and which of the two locations your comments addressing.
