This ordinance is unique because it applies specifically to agricultural use. Brown County’s Agricultural Shoreland Management ordinance is designed to “prevent soil erosion and minimize the movement of suspended solids into surface water.” It establishes a 300 foot zone on all perennial and intermittent streams and rivers wherein agricultural practices must meet NRCS guidelines. Additionally, 20-foot-vegetative buffers planted with approved seed mixtures must be established along all state waters.
