Ash Street Deep Culvert Replacement

Project Background/Summary

The existing 15-inch corrugated metal pipe (CMP) was built to convey stream flows when the ravine was filled to construct Ash Street. Over the years, the CMP has experienced severe corrosion (rusting away) and is in jeopardy of collapsing. Pipe replacement work will involve channel stabilization within the natural resource, street closure during construction and easements to operate on private property.

See Key Documents below for the project location.

If you would like more information about this project, please contact David Kudna, Project Manager at email.


On February 12, 2014, Geo-Design will be in the Ash Street neighborhood drilling two exploratory cores into the roadway to gather key information on the road subsurface. To perform the explorations they will have to close the road to thru traffic.  Driveways will be accessible either from Oak St. or Erickson St. depending on which side of the Freepons Tributary (creek) you live on.  The exploration will start at approximately 8:00 AM and be completed by 5:00 PM.
