Relating to the authority of a local government to enter into an interlocal contract with certain governmental entities to participate in water research or planning activities.

SB 480 allows local governments (like cities and counties) to form formal partnerships with other local governments, the state, or the federal government to jointly conduct water research or planning projects. The bill directly affects local governments seeking to collaborate on water resource management, such as watershed studies or drought planning. Its key provision adds a new section to the Government Code enabling these interlocal contracts without requiring additional legislative approval. This policy change simplifies collaboration but does not fund projects or alter existing water rights. The bill became effective immediately upon the governor's signature on May 28, 2025.
