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
- Draft standard (10 p., 158K, PDF)
- Draft support document (37 p., 639K, PDF)
- Pilot project final
report, 12/31/10 (69 p., 2.8 MB, PDF): MetroGIS funded a pilot project to test the draft standard with real
world data from multiple organizations.
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
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.
