Minimal Impact Design Standards (MIDS) represents the next generation of stormwater management, developed by the MN Pollution Control Agency along with its scientific, municipal and business partners. MIDS contains three main elements: (1) higher clean water performance goals for new development and redevelopment, focused on infiltrating rainwater; (2) a Community Assistance Package including sample ordinances that will allow for increased flexibility and a state-approved streamlined approach to regulatory programs (TMDLs, impaired waters) for developers and communities; and (3) the MIDS Calculator that will standardize the use of a range of innovative structural and nonstructural stormwater techniques.
Those interested in adopting MIDS may want to read about the 2016 experience of 8 cities along the St. Croix river, and view the MIDS sample ordiance language.
Use the MIDS calculator for new development and redevelopment site design.
Work with MPCA or other stormwater staff to train city staff and to introduce MIDS to the city council.
Adopt and implement the MIDS community assistance package.

Sec. 26-4 Authority and Incorporation by Reference of Statutes, Rules, and References of the Land Ordinance (Chapter 26) revised 10-16-18 includes inclusion of the Crow Wing County Local Comprehensive Water Management Plan and the “Minnesota Stormwater Manual”, Minnesota Pollution Control Agency (2005).
The vast majority of Golden Valley is located in the Bassett Creek Watershed Management Commission which adopted the MIDS community assistance package into its Watershed Management Plan in 2015. The Golden Valley City Council adopted Minnesota’s Minimal Impact Design Standards (MIDS) into its City code in 2015 as well. In accordance with the Watershed Management Plan, the City’s stormwater management ordinance requires improvements and development proposals to incorporate MIDS. Engineering staff have attended training on using the MIDS calculator.
Outcome measures/metrics/money saved:
All developments and public projects that trigger MIDS have been required to follow the new guidelines since the City code was updated. This has resulted in a reduction in the amount of stormwater volume, sediment and phosphorus entering natural receiving waters within the City.
As part of criteria for the installation or construction of stormwater management facilities in Saint Peter, the city code states that documentation showing compliance with the Minimal Impact Design Standards (MIDS) shall be provided, particularly for Total Suspended Solids (TSS) and Total Phosphorus (TP).
The City code states that Low Impact Development (LID), or green infrastructure, design concepts will be incorporated into development projects located in the northwest area and in other landlocked basins in the city. In all other parts of the city, LID design concepts must be implemented wherever possible.
The City's Water Resource Technician attended a MIDS calculator training, led by John Chapman. We are now in the process of determining how we can use the calculator and how else we can incorporate MIDS. This spring the City is hoping to kick off a rain barrel program along with some public outreach and education revolving around permeable/pervious pavement/pavers.
