Senate Bill 2191, also known as House Bill 2386, amends various sections of the Tennessee Code Annotated to establish a framework for cost-sharing agreements related to offsite public infrastructure improvements necessary for private development projects. The bill introduces a new part under Title 7, Chapter 51, which defines key terms such as "developer," "development," "offsite public infrastructure improvement," "political subdivision," and "public infrastructure." It allows political subdivisions to require developers to construct or fund offsite public infrastructure improvements, with the cost-sharing arrangement based on the development's impact on public infrastructure.

The bill also outlines the process for determining cost-sharing amounts, stating that if an agreement cannot be reached between the developer and the political subdivision, the developer may request a determination from the Tennessee board of utility regulation. Additionally, the political subdivision's share of costs can be funded through various means, including impact fees, bond proceeds, or tax revenues. Amendments to the bill include changes to the wording of certain subsections and the header for the definitions section, enhancing clarity and consistency in the legal language.
