MS4Boundaries2025c
To be used in TMDL development. This map is an approximation of MS4 boundaries. Any system owned/operated by a permittee is their regulated MS4.
<DIV STYLE="text-align:Left;"><DIV><P><SPAN>June 16, 2025 - 2025c MS4 boundaries (255 MS4s)</SPAN></P><P><SPAN>Removed North Hennepin COmmunity College, cleaned up some transportation MS4 boundaries (eliminated internal polygons <250 sq M).</SPAN></P><P><SPAN>All MS4 boundaries have been updated from 2024 versions.</SPAN></P><P><SPAN>All MS4s are erased from all other MS4s (except for county and MnDOT MS4 from each other). Previously, non-traditional MS4s like colleges, universities and entire watershed districts laid on top of cities and townships.</SPAN></P><P><SPAN>County and MnDOT are only road right of ways and county/MnDOT-owned parcels within the 2020 Decennial Census urban area with populations over 50,000. </SPAN></P><P><SPAN>Watershed district MS4s have been narrowed down to just include specific MS4 conveyance and BMPs. Previously it was denoted as the entire watershed district within an urban area.</SPAN></P><P><SPAN>2025b MS4 Boundaries (based on April 2025 City, Township, Unorganized Territories boundaries for cities and township and Fall 2024-Spring 2025 effort to update all nontraditional MS4s (colleges, universities, watershed districts, counties and MnDOT). </SPAN></P><P><SPAN>This file includes all currently regulated MS4s, (except Stillwater prison, as they no longer have regulated MS4 since they are outside of the 2020 Urban Area). Otherwise it doesn’t exclude any MS4s that may be removed in the near future due to changes in Urban Area (those 11 can be identified by the text “Platted area” in the Census notes field). </SPAN></P><P><SPAN>This file includes the 13 new city and townships (no Permit ID #, and the text “Special and Impaired” in the Census notes attribute field) and one new county MS4 (Wright) that will be brought into the program after the next permit is issued.</SPAN></P><P><SPAN>This is not the same layer that is available on MNGeo and L Drive: the county/MnDOT/WD MS4s available publicly are based on 2010 Census UA, are not erased from other MS4s, and are the full extent of each entity in the urban area. Additionally, there is a different split for Metro and Outstate MnDOT. </SPAN></P></DIV></DIV>
