Metro Stormwater Geodata Project

The MetroGIS collaborative is working with a broad group of interested public and private stakeholders toward the development of a multi-purpose stormwater transfer 
standard. This stormwater geodata transfer standard is intended to eventually serve as a means to federate a regional stormwater system dataset in the metropolitan region to meet a range of known business needs including routing and integration with asset management.


Prototype Stormwater Data Standard

Below are the Excel spreadsheets containing the initial versions of the MSWGP's prototype stormwater transfer standard. The current prototype version is 'v. 0.4.2' which will be reviewed and disucssed at the upcoming Steering Team Session on August 27, 2019 at the City of Bloomington.

Additionally, materials for the upcoming pilot project and the draft version of the MS4 inspection schemas are also found below. 

Please note: All of these materials will be continually reviewed, edited and reworked during 2019 by the MSWGP Steering Team and its constituent work groups and are subject to change.

Also, please take note of the date of publication for each document we have made available and check back frequently for updates as these materials are still in development.

Context and Background

Work on the Metro Stormwater Geodata Project (MSWGP)  commenced in April 2018, with presentations and stakeholder input sessions on April 17 (in Medina) and June 12 (in St. Paul) and the formation of a Steering Team convening for the first time on June 26, 2018 in Minneapolis.

The MSWGP project aims to:

  • Engage both the data producer and data consumer communities to discover what business needs they have for an inter-jurisdictional stormwater dataset and accompanying data standard;
  • Collaboratively work toward developing a data transfer standard and developing work flows, agreements and understandings between participating partners;
  • Document and address policy issues surrounding data availability and protection of assets;
  • To identify and capitalize on both existing formal and informal relationships in place among the partners in working toward federating the data together;

Building upon prior work...

The MSWGP builds upon prior efforts in Minnesota to develop a data transfer standard for stormwater information. In 2010, an initial Draft Digital Stormwater Data Exchange Transfer Standard was developed, as well as a pilot project focused on gathering and assessing data in the Battle Creek Sub-Watershed of the Ramsey-Washington-Metro Watershed District.

Documents on the original Draft Stormwater Standard can be found here.

An Excel spreadsheet version of the original 2010 Draft Stormwater Standard can be found here: Excel Version of Draft Stormwater Standard
