Transportation Committee:
This is a followup to a conversation Marcie and I had around noon today.
We met with WSDOT today and we have this to report:
There are two parts to the repair: the temporary repair and the permanent one.
The temporary one is intended to handle any more severe rain fall in the next several months. It consists of the installation of 3 – 24 inch pipes to convey water, plus 15 pumps and generators. This work is supposed to be completed before year’s end, or even slighly sooner (no one is eager to work over Christmas).
The permanent replacement of the 48 inch culvert will be designed and awarded before the end of January with completion by end of March.
The estimated cost is $5 million for the permanent, and $2 million + $250,000 in equipment rental for the temporary.
WSDOT does not anticipate a lot of lane closure after this week and very little thereafter.
