We just heard that the centuries-old oak tree that we protested to save this summer will be spared:

A centuries-old oak tree in San Mateo County in the path of a $4.6 billion water system upgrade will be preserved thanks to an agreement reached between neighbors, the county and the San Francisco Public Utilities Commission.

The tree, which North Fair Oaks neighbors nicknamed "Granny" and is estimated to be at least 150 years old, stands in the path of a project to upgrade the Hetch Hetchy water delivery system so that more than two million Bay Area residents will have a safe water supply in the event of a major earthquake.

Negotiations to preserve the valley oak reached an impasse in August, but on Monday the SFPUC, the county and neighbors jointly announced that public money will be spent to tunnel beneath the tree's roots to allow the construction of the new water supply pipeline to move forward.
