Mr. G tips us off about this: ``A private contractor team came down Alabama Street (from Ripley to Precita) on Friday 1/30/09 and drilled holes in the street about every ~ 4-10 feet.``




We did some further investigation and found that the hole drilling actually goes from the 100 block of Bernal Heights Blvd (near Bradford), heads north/downhill to Esmerelda towards Alabama, and all the way down Alabama to Precita, where they turn East and go down Precita to Bryant.

All along this way, there are also underground survey markings for all the underground water, gas and electrical services.

It is very similar to the path that the Bernal Hills Water Pipeline takes under Bernal Hill. This is the same pipeline that was replaced over the last 18 months, and terminated at Alabama and Ripley.

Alabama street is already a major "right of way" for other utilities. There are several fiber optic lines going down Alabama (ATT, Qwest, MFN, Level 3 and CCSF/City of San Francisco's fiber ring are all ones that have manhole covers up and down the street with their names on them). We're trying to track down more details on who what the project is, and how long it will be tearing up Alabama.

You've probably noticed the water leaks on Harrison just uphill of Precita. DPW on Friday was trying to locate the exact underground location of the leak, but the leak hasn't been fixed yet.



This is the second leak of that kind in the last year that we know of, the last one was up the hill a bit more.

The SF Water Department staff told Precita.org that the water line the 3200 block of Harrison is almost 100 years old. One house on Harrison still has the original building permit to connect to the water main dated 1910.

The water main will need to be replaced at some point in the future, else residents will be getting a lot more visits from DPW to repair the leaks the spring up. The water line is a 3" pipe going up the street. It's amazing that it has lasted as long as it has!

In the mean time, if you see any more instances of water seeping up from the street, please call 311 and report it.

On Harrison, above Precita, there has been water leaking from the curb area for a couple weeks. Some neighbors called 311 about it, and the water department came out and replaced the water line that feeds fresh water to the house by the leak.

Mary Ann from Bernal Hill Realty sent us some pictures of the work:

If you drive from Precita up to Bernal Hill on Alabama, you'll see a lot of construction. It's the "Bernal Heights Pipeline", which is being replaced by digging a tunnel under Bernal. Tikirobot has some good pictures and more information about this.

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.
