The City is starting a project to stop rainwater from entering the sanitary sewer system. The work will happen near 22nd Ave N and 23rd Ave N and 2nd St N.
To fix the problem, the City will improve how rainwater flows at these two locations:
- 22nd Ave N and 2nd St N (CSO 001)
- 23rd Ave N and 2nd St N (CSO 117)
We are getting the necessary permits for the project now. Construction should begin soon.
