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.

Thank you to 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.

As a non-profit organization, we rely on the generosity of our members and other business partners as well as foundations in order to implement our programming.

As our thank you for your commitment to SBN and our mission, we provide a number of benefits to our sponsors, including visibility, business connections, and access, thereby helping you position your business as a leader in the local impact economy. We are seeking mission-aligned sponsors who are committed to supporting our mission, learning, sharing, and improving their triple bottom line.
