Draft Digital Stormwater System Data Exchange Standard for Minnesota

Many cities, townships, and other entities collect data on geographic features that comprise their stormwater system. The proposed draft standard defines a set of specifications for the exchange of digital stormwater system data. The standard was created to increase the ease and efficiency with which stormwater system data can be compiled for multiple organizations into a single system, or shared by adjacent owners of stormwater systems.

While there is no requirement that any entity in Minnesota comply with this standard, it is offered to provide a single, sanctioned output format that will facilitate efficient data handling and integration.

Public Review

The Metro Stormwater Geodata Project (MSGP) has developed a stormwater geodata exchange standard based on the input and business needs of the stakeholder community in the Twin Cities metro region.

The MSGP partners built upon the original Draft Exchange Stormwater Data Standard (see Archive section below). The emerging standard seeks to accommodate key business needs such as flow routability and ease of integration with asset management software.

The MSGP effort is a collaborative project led by MetroGIS, the Hennepin County GIS Office and the Ramsey-Washington Metro Watershed District and includes geospatial, engineering and stormwater professionals from all levels of government and the private sector.

The revised draft standard (v. 0.6) was open for public review until September 3, 2021. For more information, see:


The original version of the standard was drafted between 2008 to 2010 by the Standards Committee's Stormwater Systems Workgroup, a multidisciplinary team representing public and private entities.

A support document defined features and attributes, provided specifications for encoding the attribute data, and linked to websites that illustrated examples of features and attributes. It also listed the people who helped develop the standard, described the development process and included feedback by initial reviewers.

The public review period for this earlier version closed December 15, 2010, and the committee and workgroup reviewed the comments.
