Before beginning any activity that alters an existing lake, stream or wetland, contact your County Conservation District for required permitting and other helpful information. Buffer characteristics can vary widely depending on local circumstances. However, it is important to understand certain basic, minimum criteria. The U.S. Department of Agriculture recommends filter strips of 66 to 99 feet for water quality protection.
Access typically is provided via a mown footpath.
Less intrusive pedestrian access could be provided via a stepping stone trail. Paving through a buffer is discouraged. One reason is that in general, native species are established more successfully. Properly selected native plants, for instance, are usually able to withstand extended periods of drought or inundation. They also can prove to be easier to maintain.
