The bill introduces a new section to chapter 46A-10A of South Dakota law, allowing counties to administratively approve certain drainage applications through a designated drainage administrator. This administrator is empowered to grant or deny permits for drainage projects that outlet into specific waterways, including named creeks, permanent or intermittent streams, public or private road right-of-ways, and unnamed waterways. The bill outlines the conditions under which these permits can be granted, such as obtaining written approval from affected landowners and the appropriate road authority when necessary.

Additionally, the bill defines "affected landowners" as those who are upstream within one-half mile, downstream within one mile, or within one-quarter mile surrounding the project. It stipulates that all other drainage permit applications must be reviewed by the board or commission according to the existing permit system. This legislative change aims to streamline the drainage permitting process while ensuring that landowners' rights and environmental considerations are respected.
