Did you know San Bruno Creek is more than just a waterway? It’s a thread woven into the very fabric of San Bruno’s history. Let me tell you its story.
San Bruno Creek originates high in the Northern Santa Cruz Mountains. It begins as an intermittent stream. Its waters carve through a steep canyon. The creek’s journey is a winding path east of Skyline Boulevard.
Centuries ago the Buriburi tribe of the Ohlone people called these banks home. They lived here as early as 2000 BC. Imagine a small settlement of perhaps 15 to 25 people. They built their lives alongside San Bruno Creek.
Fast forward to 1769. Spanish explorers arrived. Gaspar de Portolà led the expedition. Later Bruno Heceta explored more extensively. He named San Bruno Creek after St. Bruno of Cologne. St. Bruno founded a medieval monastic order. The creek then lent its name to the community that grew around it.
With the establishment of Mission San Francisco de Asís, the area transformed. San Bruno Creek’s watershed became pasture. Livestock grazed on the land. After the missions declined, the watershed became part of Rancho Buri Buri. José de la Cruz Sánchez owned it. He was the eleventh Alcalde of San Francisco. Dairy farms became common here.
An early map from 1893 shows San Bruno Creek sharing headwaters with another creek. Andrew Cowper Lawson created it. He was a geology professor at UC Berkeley. This other creek drained into what is now Crystal Springs Reservoir. The city of San Francisco later developed the reservoir. Urbanization also changed the creek’s course.
Today, a hiking trail follows San Bruno Creek. It forms a key part of the San Francisco Bay Trail. This trail makes up for limited access along the bay front. The airport occupies much of this area. The Bay Trail detours inland for two miles.
Above the intersection of Interstate 280 and Interstate 380, the creek flows through Crestmoor Canyon. The creek also passes through the Crestmoor neighborhood. This area was the site of the tragic 2010 gas pipeline explosion.
The upper reaches of San Bruno Creek are particularly rugged. The stream flows through canyons with slopes of about 45 degrees. This upper basin consists of Pleistocene Colma Formation. Groundwater flows eastward toward the Bay.
The upper watershed has mixed oak woodland. Coast live oak is a dominant species. You’ll also find California Bay Laurel and Toyon. Wildflowers add color to the understory. Evening primrose and wild radish bloom here. You might also spot wild cucumber, scotch broom, or miner’s lettuce. Fillaree, vetch, sweet clover, lupine, and California poppy also grow.
San Bruno Creek has faced challenges. Urban development has significantly altered its lower reaches. Yet, efforts are underway to address these challenges. OneShoreline is working to mitigate flooding. They are engaging with local communities. They aim to develop sustainable solutions.
San Bruno Creek’s story is one of transformation. It reflects the changing landscape of San Bruno. From Ohlone settlements to Spanish exploration to modern urbanization, the creek has witnessed it all. As you explore this area, remember the rich history that flows with San Bruno Creek.
