Shaping San Francisco
hills, water & why SF is here

How did the city come to be here, of all places, on all these hills? And surrounded by salt water! The answer: politics and ground water. Take a walk along hidden fresh water rivers, hear waterfalls (cascading beneath ornate sewer covers), and discover lost wells within the city. Learn the power of drips—elected and unelected.

We'll examine water's artful sculpting of our hills and shorelines with a special tour based on this book chapter by our founder and lead guide, Joel Pomerantz.

Water is coming to be more precious than oil. With wars of the future likely to be fought for control of this basic resource, we'd do well not to take water for granted.

San Francisco's regional power is originally derived almost entirely from water. According to historian Gray Brechin, our drinking and irrigation water system was purposely designed on the model of ancient Rome, in order to dominate the West economically, as Rome dominated its empire.

This tour could be a watershed moment in your life!
