Less gray,
more green.
Let's transform San Francisco now with sustainable green infrastructure solutions for cleaner water, recharged aquifers, better biodiversity, and safer streets.
What is Green Infrastructure?
Light Green Infrastructure
Surface-level improvements create more ways for plantings to hold and divert water, cleaning the air, filtering water, and reducing toxic runoff during storms. These solutions are less costly to install while providing multiple environmental benefits, including reduced flooding, increased humidity to mitigate fire risk, and enhanced local biodiversity.
Deep Green Infrastructure
Sub-surface infrastructure represents more comprehensive, collective efforts that update waste treatment systems with nature-based solutions and long-term vision. While more complex to implement, these improvements address interconnected environmental challenges, including sea level rise, and collaborate with connected water systems to ensure maximum protection of fragile ecosystems.
Why It Matters
💧 Clean Water
Reducing combined sewer overflows by diverting stormwater before it enters treatment facilities helps prevent untreated sewage from reaching the bay and ocean. San Francisco can become a leader in voluntary green infrastructure implementation even without EPA mandates.
🌊 Aquifer Resilience
Capturing rainfall where it falls recharges local aquifers, providing critical backup water supplies during emergencies while reducing pressure on the Tuolumne River watershed, supporting endangered salmon populations and ecosystem restoration.
🌱 Biodiversity & Wellbeing
Green infrastructure restores native ecosystems, expands our inequitably distributed urban tree canopy, and mitigates urban heat islands, creating healthier, more comfortable neighborhoods where people and wildlife can thrive.
🚶♀️ Safe Streets
Green features like bulb-outs improve visibility and shorten crossing distances, while planted medians and bioswales create protected spaces for active transportation and naturally calm traffic, making streets safer for everyone.
