Metro Stormwater Geodata Project

About the project.
MetroGIS in partnership with Hennepin County, Ramsey County, Ramsey-Washington Metro Watershed District and the University of Minnesota Water Resources Center is working with a broad group of interested public and private sector stakeholders toward the development of a multi-purpose stormwater geodata transfer standard.


Purpose of the standard. This stormwater geodata transfer standard is intended to meet a range of known business needs including flow modeling, conflict detection, to faciliate data integration between GIS and asset management systems and to assist in identifying asset ownership and maintenance responsibility. Longer term, this geodata standard is intended to eventually serve as a means to federate data to create a regional stormwater system dataset across the metropolitan region.
 

Draft Stormwater Data Standard

The MSWGP Steering Team has been working since mid-2018 to create a draft stormwater geodata transfer standard and a template for MS4 site inspections of inlets, outlets and stormwater ponds and basins.

In March 2020, the team finalized its documents and now offers this material to the entire stakeholder community for review, comment and input.

>> Draft Inspection Schema document (41 pages)
>> Draft Data Standard document (161 pages)
>> Excel spreadsheet versions of the schemas

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
