At work again.

The same workman were back so I drove down to take a look.
(sorry, no picture. Didn't have camera with me)
Their trucks all said "Harvest Monovia Water Authority".
They were in a ditch down in the creek bed. I surmise that they are moving/replacing/repairing a water main that was cut to install the new bridge foundation (seen in this earlier picture - the green pipe below the raccoon).
I hate to think that the half month delay we just went through was waiting for the County to come and do this.

(I believe this is the pipe the county was working on. This photo was taken on the 10/31)
