SBN’s Annual Sponsors

Our work would not be possible without our sponsors. They provide extra financial support for our work, and we ask you to do the same for them.


GSI Partners Funders

The work of the GSI Partners is supported by generous grants from the Surdna Foundation and the William Penn Foundation. Our work aligns with their goals of watershed protection, strong local economies, thriving communities, and the many other triple bottom line benefits of green stormwater infrastructure.
