More Treat Ave street work?
``The city is going to do construction to fix the pot holes.`` Was the response. ``Not us, the City``.
You may remember, between October 2003 and Feb 2004, the city replaced the sewer line going down Treat ave. They opened up a 2 foot trench in the middle of the street, replaced the sewer lines, repaved the street and also replaced the curbs on the street.
Apparently, they didn't do something right when they closed up the trench in the middle of the street, because it has been sinking. There are numerous potholes, including the rather large one that appeared in January 2008, so hopefully the construction will be done properly this time.
However, we might be in for another 2 months of Treat being under construction again, like it was in last 2003.
(Here are some pictures from the 2003/2004 sewer replacement on Treat)

The photo below shows a cross-section of the street after it was cut through. Notice the old cobblestones/ bricks under the asphalt.


The new sewer line. They would rip out the old pipes, and immediately replace it with the new pipes.



The new pipes were laid in a bed of gravel, our understanding is because that gives the pipes a bit of room to move during an earthquake.

If you know anything more about this construction, post a comment. Calls to 311 were directed to a voicemail number for DPW, who didn't return our call.

The tunnel under Bernal
Construction Update: Affholder Construction, the tunneling contractor continues boring work within City property through Bernal Hill. The closure of Powhattan Street between Nevada & Nebraska (the "tunnel head") continues until October. Work continues at Cortland Avenue and Nebraska Streets. Some parking has been temporarily removed at Alabama & Ripley and traffic patterns have slightly changed. The storing of some materials and equipment is located at Powhattan & Nebraska and also at Bernal Heights Boulevard near Bradford Street.
The target completion date for this project is October 2007.
Work has now started at Ripley and Alabama, another "tunnel head". Apparently, the tunnel goes directly under some homes. The old tunnel went directly under some homes, but the new tunnel is trying to avoid going under homes. (This is what I've been told, but don't have a reference to back it up.)
Here's a map of the San Francisco water system. You can see this main on the upper left side of SF.
