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.

 

Prototype Stormwater Data Standard

Release and review. The current prototype version of the standard is referred to 0.5 ("dot five"). This version reflects the many discussions, edits and revisions of the MSWGP Steering Team and Structures Team which occured during 2019.

The v. 0.5 will is now informally available for public review from November 2019 through Februrary 2020.

In February 2020, a formal public outreach effort will take place and stakeholder comments will be solicited from the engineering, asset management, water modeling, planning, landscape architecture, water quality and other professional communities.


The MSWGP Steering Team very much welcomes the input, insights and suggestions for improvements to this evolving schema, please make use of the contact info at the bottom of the page if you would like to contribute comments formally or informally.

Pilot Project - Sample Dataset

The MSWGP has worked from April 2018 until October 2019 to develop a Stormwater Geodata Transfer Standard (SGTS) schema that it feels would satisfy core business needs such as integration with asset management, flow modeling, determination of ownership, linkage to as-built drawings and other uses.

The MSWGP team will be working with partners at the City of Bloomington, City of Eagan, Minnesota Department of Transportation, Hennepin County, Dakota County and the Metropolitan Council to prepare a sample dataset in the proposed schema format.

This pilot sample dataset will be made available for the stakeholder community to download, review, test and work with so that they can provide comments for its revision and improvement.

The MSWGP Pilot Team will be working during November 2019 through early 2020 to create the sample dataset. That dataset will be available here once it is ready.

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
