What must counties and cities agree on according to Georgia law?

Counties and cities in Georgia must agree on the provision and payment of local government services. This is a fundamental aspect of local governance and intergovernmental relations. Local governments often work collaboratively to provide essential services such as public safety, education, waste management, and infrastructure maintenance. The need for agreement ensures that there is clarity on resources, responsibilities, and funding mechanisms to efficiently meet the needs of the communities they serve.

In contrast, the other options involve aspects that are not typically governed by direct agreements between counties and cities. For instance, state funding is typically allocated from state to local entities based on established criteria rather than mutual agreement. The election of local officials is primarily governed by state laws and regulations, rather than agreements between different levels of local government. Additionally, limits on tax collection are often regulated by state law rather than through collaboration between counties and cities, even though local entities must adhere to these state-defined limits. Thus, the correct answer underscores the collaborative effort required in local governance related to service provision and funding.
