A bill for an act relating to surface water quality by requiring the establishment and maintenance of riparian protection measures, providing for financing, and providing penalties.

SF 435 requires agricultural landowners near waterways to establish and maintain vegetated riparian buffers (riparian protection measures) along streams and rivers to improve surface water quality. It directly affects agricultural landowners adjacent to public water sources by mandating these buffers, though implementation is tied to available cost-share funding. Key mechanisms include prioritizing financing for these buffers through soil and water conservation districts, requiring districts to focus on riparian protection in their planning, and establishing enforcement through administrative orders for non-compliance. The bill defines "riparian protection measures" as buffers or approved alternatives, with penalties for failing to meet requirements after funding is made available.
