Regulatory Program Background

Photography by: Mike Thorud

In 2008, the NMCWD Board of Managers adopted its current rules. The rules resulted in an expanded regulatory program that focused on volume control (treating water where it falls) and stronger wetland regulations, in addition to regulations for sediment and erosion control, floodplain management, water appropriations, water quality management, waterbody crossings, and shoreline and streambank improvement.

Legal Authority

Legal authority for the NMCWD’s rules derives from Minnesota Statutes Chapters 103B and 103D. Under Minnesota Statutes § 103D.341, subdivision 1, watershed districts must adopt rules “to accomplish the purposes of [the watershed act] and to implement the powers of the managers.” These purposes include, among others, conservation of water for public uses; controlling erosion and siltation of lakes, streams, and wetlands; and protecting water quality in these bodies. Minn. Stat. § 103D.201, subd. 2. District managers are further authorized for example, to regulate and control the use of water within the watershed district, regulate the use of streams and watercourses to prevent pollution, and regulate the use and development of land under certain conditions. Id. § 103D.335, subds. 10, 16, and 23; § 103B.211, subds. 1.

Amended Rules

The NMCWD adopted a new Water Management Plan in 2007. The new 2007 plan outlines the goals of the NMCWD. The amended Rules, adopted in 2008, implement the policies and goals articulated in the NMCWD’s updated Watershed Management Plan, adopted in March 2007. The amendments substantially revise the prior NMCWD Rules, which were adopted in 1973. The amended NMCWD Rules regulate floodplain management and surface drainage alterations, wetlands management, stormwater management, erosion and sediment control, waterbody crossings, shoreline and streambank improvements on public waters, sediment removal from public waters and appropriations from public surface waters. In addition, the amended Rules formalize the NMCWD’s project-review process, and implement permit fee and surety requirements, pursuant to watershed district authority under Minnesota Statutes Section 103D.345.

The NMCWD’s rules include a number of key elements:

  • Required compensatory storage for any encroachment in the floodplain, evincing a no-net-loss policy on floodplain storage;
  • Enhanced protection of the remaining wetlands within the watershed through replacement ratios that strongly discourage alteration of wetlands and a provision requiring buffers around all wetlands in the vicinity of development or redevelopment projects;
  • Increased focus on retention of stormwater and snowmelt on site to reduce discharge rates and volumes, provide flood control, enhance erosion and sedimentation control, and improve the quality of the water resources in the watershed. The rules establish a runoff volume-banking system to enhance the effectiveness of and prospects for the success of the NMCWD’s volume-retention requirements; and
  • The application of erosion and sediment control regulations to single-family home construction and redevelopment projects.

The District Board of Managers adopted the amended rules on March 19, 2008, at its regular monthly Board of Managers meeting.
