The 2026 Regular Member Application from the California Special Districts Association (CSDA) outlines the process for independent special districts and public agencies to apply for voting membership. It includes details on membership dues, which are determined by the district's annual operating revenue as of June 30, 2025, and provides a dues table for various revenue categories. The application must be submitted along with the appropriate dues, and members who join in 2026 will receive a prorated invoice for 2027.
