Instead of steep concrete barriers, the project creates a gentle earthen slope with native plantings that transition from tidal to freshwater marsh. The system also filters wastewater through vegetation to remove nitrogen and phosphorous before it reaches the bay. This approach aims to prevent erosion while supporting native species like the Ridgway's rail and salt marsh harvest mouse. If successful, the pilot could inform coastal defense strategies across the San Francisco Bay Area and beyond. ## Full article daily.dev links to this article rather than hosting it.
