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.

An extensive support document accompanies this standard. It further defines and explains features and attributes, provides specifications for encoding the attribute data, and links to websites that illustrate examples for features and attributes contained in the standard.

The standard was drafted by the Stormwater Systems Workgroup, a multidisciplinary team representing public and private entities. See the support document for a description of the development process, detailed feedback by initial reviewers, and a list of people who helped develop the standard. The public review period for comments and recommendations for improvement of this version of the proposed draft standard closed on December 15, 2010. The Committee and Workgroup reviewed the comments and recommendations.

Next Step:  Metro Stormwater Geodata Project

As of April 2018, the Metro Stormwater Geodata Project (MSGP) has been actively working to develop a stormwater geodata exchange standard based on the input and business needs of the stakeholder community in the metro region.

The MSGP partners are currently building upon the original Draft Exchange Stormwater Data Standard that was developed between 2008 to 2010. 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.
