Title:
Municipal Separate Storm Sewer System (MS4) boundaries in Minnesota
Abstract:
In general terms, MS4s are publicly owned or operated stormwater infrastructure, used solely for stormwater, and which are not part of a publicly owned wastewater treatment system. Examples of stormwater infrastructure include curbs, ditches, culverts, stormwater ponds and storm sewer pipes.
By federal rule, stormwater systems in urban areas are labeled Mandatory MS4s. By state rule, permit applicability is based on urbanized area as defined by the latest decennial census, population, and proximity to special receiving waters (e.g., trout streams, Outstanding Resource Value Waters, and impaired waters). In addition, Minnesota requires MS4s located at least partially within an urbanized area that have resident capacity, bed count, or average daily user population of 1,000 or more to obtain a permit. These are referred to as non-traditional MS4s.
MS4 owners must establish stormwater pollution prevention programs that include public education and involvement, illicit discharge elimination, construction-site runoff controls, and stormwater best management practices.
Purpose:
The locations of MS4s provide information and context to support decisions on stormwater management.
Time Period of Content Date:
03/11/2024
Currentness Reference:
This dataset was created using data as old as 2000 and as new as 2024. It was updated, after 2010, using newer data obtained for non-traditional MS4 boundaries.
Progress:
In work
Maintenance and Update Frequency:
As needed
Spatial Extent of Data:
All MS4s lie within the state of Minnesota.
Bounding Coordinates:

Access Constraints:
None
Use Constraints:
This dataset is intended only for mapping general locations and approximate spatial extents of MS4s in Minnesota.
Boundaries for corrections, education, and healthcare MS4s (subtypes) outside the metro area were based on minimal available public data on approximate location and extent. Boundaries for these MS4s inside the metro area were based on 2005 parcel data. In addition to the issue of currentness of the parcel dataset, during feature digitizing various errors were observed in 2005 parcel geometry, alignment, and attributes.

Attribute Accuracy:
The attributes have been checked and are expected to be reliable.
Logical Consistency:
Completeness:
This dataset accurately identifies all permitted MS4s at the time of publication.
Horizontal Positional Accuracy:
unknown
Vertical Positional Accuracy:
unknown
Lineage:
Some MS4 polygons were reused from previous MS4 shapefiles. The City, Township, County, MN DOT, and Watershed District polygons are the most updated, as they were completely recreated from new data. The polygon geometry and population values for the 'City or Township' polygons are derived from the MNDoT Cities, Townships, and Unorganized Territories (CTU) data layer (https://gisdata.mn.gov/dataset/bdry-mn-city-township-unorg).
