Tour Overview
This walk covers the mostly buried Temescal Creek through the upper portion of the Rockridge neighborhood. Most of what you will see was part of a "whites only" neighborhood developed in the 1920s. Where the freeway is now was originally covered with freight and passenger rail lines.
Along this walk you will encounter a very important piece of water infrastructure in this area: the Claremont Tunnel. Through this pipe flows water from the Mokelumne River and it provides up to 175,000,000 gallons of water each day to 800,000 East Bay Municipal Utility District (EBMUD) customers.
