A more thorough explanation:

A joint powers agreement is a contract between two or more public agencies, like a city, county, school district, or special district. This agreement allows the agencies to work together to provide services or exercise shared powers outside of their normal jurisdiction.

For example, a city and a county might enter into a joint powers agreement to share the cost of a new park that is located on the border between their jurisdictions. The agreement would allow both agencies to contribute funds and resources to the project, and to jointly manage and maintain the park once it is built.

Another example might be a joint powers agreement between a school district and a city to provide after-school programs for students. The agreement would allow the school district to use city facilities and resources to offer programs that benefit students, while the city benefits from having more young people engaged in positive activities.

Joint powers agreements are a way for public agencies to work together to achieve common goals and provide better services to their communities. By pooling their resources and expertise, agencies can often accomplish more than they could on their own.
