Before San Francisco was even a city, the landscape was a swampy land crossed by vast network of hallows, creeks, marshes and bay waters. These areas were covered up as the city grew on top of them, but they continue to shape the San Francisco even to this day. The water continued to flow, however, shaping a path beneath our roads, sidewalks and homes.
Some neighborhoods have even shifted after being built on active watersheds. This water was once used for irrigation, fountains and street cleaning, but the initiative was abandoned over 30 years ago for unknown reasons.
This was only a small part of the vast water system that spanned the peninsula, making in the beautiful home that attracted so many plants, animals, and eventually people.
