San Francisco Bay Delta

Healthy Watersheds, Resilient Baylands

This project focuses on watershed redesign, tidal wetlands restoration and urban greening efforts. The San Francisco Estuary Partnership (SFEP) together with the San Francisco Estuary Institute and 15 other local organizations, will implement several projects that will improve resilience to climate change impacts in the South Bay. The cities of Sunnyvale, Mountain View, and East Palo Alto will build green infrastructure projects to reduce stormwater runoff, capture pollutants, and create 13 acres of native wetland and riparian habitats In addition, the Santa Clara Valley Water District is a key partner for the design and realignment of Calabazas and San Tomás Aquino Creeks which will reconnect watersheds to the baylands and reduce flood risk.

Incorporate Multi-Benefit Urban Greening Strategy into 5 local/regional plans

Treat stormwater from over 60,000 ft.² of impervious surface in industrial area capturing 0.14-0.78 g PCBs and Hg each year, as well as 40 – 80% of metals and PAHs (Caribbean Ave.)

Create 3,000 ft.² of native plant and seasonal wetland/ willow swale habitat adjacent to baylands (Caribbean Ave.)

Create 8 acres of native plant, seasonal wetland, and willow swale habitat in the urban setting (Mountain View, Google)

Restore 3 acres of native riparian trees (live oak, valley oak, sycamore, willow) in urban greening projects, providing riparian function and habitat connectivity for native birds, bats, and insects (East Palo Alto)

Reduce runoff by over 400,000 gallons per year from increased tree canopy (East Palo Alto)

Increase tidal circulation in 1,400 acres of Pond A8, resulting in anticipated reduced methylmercury exposure for Bay wildlife

Reduce risk of contamination of Pond A8 and SF Bay from the adjacent landfill

Create 10 acres of tidal marsh ecotone habitat, including 5 acres of seasonal wetlands

Realign 2 major watersheds into restored tidal marsh, potentially delivering ~50,000 cubic yards/yr of sediment

Reduce habitat impact, reduce cost, and improve permitting efficiency for maintenance dredging of Calabazas and San Tomas Aquino creeks

Reduce risk of flooding to Alviso and Sunnyvale

Develop new sediment monitoring plans for SF Bay

Inform the Nutrient Management Strategy for San Francisco Bay

Install hundreds of multi-benefit urban greening projects throughout Silicon Valley

Create native habitat corridors and improved water cycle for Bay and watershed wildlife

Reduce PCB loading to the Bay cost-effectively through a wide range of urban greening efforts

Reduce stormwater runoff, reduce urban temperatures, and increase carbon storage and rainfall interception with expanded tree canopy

Reuse millions of cubic yards/yr of dredged Bay, flood control channel, and reservoir sediment for tidal wetland restoration projects

Restore 1,400 acres of resilient tidal marsh in the Pond A8 complex, creating tidal wetlands with reliable sediment supplies for sea level rise resilience

Manage Bay suspended sediment for nutrients and other water quality objectives
