SSDN works with its national partner, and fiscal sponsor, the Urban Sustainability Directors Network (USDN) to bring resources to the Southeast from the national sustainability context, as well as tools to support a broader understanding of the Sustainability field of practice.

Via its website (, USDN offers SSDN members a private, accessible platform on which to share questions, events, files, and more. SSDN hosts a Southeast-specific group via the USDN website for members to ask questions, share advice, and make use of the SSDN Member Resource Library, a catalogue of files (presentations, templates, guides, research, reports, etc.) related to priority topics identified by our membership.

All SSDN members are eligible to receive a login to the USDN website to access regional content and the SSDN group. Once you have a log in, you can post questions, upload content, and add information to posts and updates.
