Buffer Law Continues Making Headway

Nearly a decade after Minnesota's buffer law was enacted in 2015, 99.8% of parcels adjacent to Minnesota waters are in compliance with the law. Buffers are also known as a riparian filter strip adjacent to a stream, river, lake, or wetland. These buffers filter out phosphorus, nitrogen, and sediment. Studies completed by the Minnesota Pollution Control Agency show that buffers are important for protecting and restoring water quality, natural stream functions, and aquatic habitat and life. Buffers are required along public waterways and ditches. Public waterways include lakes, rivers, and streams. This type of waterway requires a 50-foot average buffer. Buffers of 16.5 feet are required along public ditches. 

ACD was proud to announce that Anoka County was 100% compliance back in fall, 2020. This milestone was achieved through strong partnerships between Anoka County, ACD, local landowners, and BWSR. This achievement doesn't mean that the hard work is over but it does represent a great success and displays the impact that strong environmental policy can have across the state of Minnesota. The next phase, includes another ACD review of properties throughout Anoka County to identify non-compliant parcels. This review began in Spring, 2024 and is based on recently released aerial photos. Compliance status and progress is tracked using the Buffer Compliance and Tracking Tool (BuffCAT), a state developed GIS database and mapping system.

Transfers in property ownership and land management changes, will require ongoing efforts by ACD in order to maintain existing compliance and to bring other parcels into compliance. Many landowners with noncompliant parcels have plans in place to seed the sites, or to implement an alternative conservation practice that provides comparable water-quality benefits this spring.
