A new version of the MIDS Calculator is now available in the Minnesota Stormwater Manual. Changes over the last 6 months include:

  • Tree trench/box credits for canopy interception and evapotranspiration
  • Bioretention with underdrain updated to apply the equation for phosphorus credit reduction based on media depth.
  • Summary table of total phosphorus and total suspended solids percent removal by BMP on the summary tab of the calculator
  • Annual runoff volumes to BMP summary tab was added
  • Bioretention media phosphurus credits to tree box/infiltration trench with underdrain
  • Bioretention medial phosphorus credits to swale with underdrain was added
  • Sizing inputs for stormwater ponds
  • Swale annual TSS, dissolved phosphorus and particulate phosphorus removals were adjusted
  • A stormwater reuse function!

A few other minor updates were also made. You can now download this new version of the calculator. Remember to delete your current version before downloading the new version. Here's the link to download the calculator: http://stormwater.pca.state.mn.us/index.php/Calculator

Mississippi River Corridor Critical Area Rulemaking

Posted By MNLA eNews, Thursday, June 19, 2014

Working Draft of Rules Released

 

The DNR is soliciting public comments on potential rules for the Mississippi River Corridor Critical Area (MRCCA). A Request for Comments was published in the June 2, 2014 State Register, and the DNR will accept comments through August 15, 2014. The DNR has developed a working draft of the rules following consultation with local governments and other interested parties, now available for review during this comment

period.

 

The Mississippi River Corridor Critical Area (MRCCA) is a unique land corridor along the Mississippi River within the seven-county metropolitan area. Land development in the 54,000-acre corridor is currently guided by state regulations that are implemented through local plans and zoning ordinances.

 

The MRCCA was established in the 1970s by Executive Order, a type of state regulation that cannot be readily changed or updated. In 2009, the Minnesota Legislature directed the DNR to establish rules to replace the outdated standards in the Executive Order.  The rulemaking process was put on hold in 2011 and the DNR's authority expired. In 2013, the Legislature restored DNR's rulemaking authority and made changes to the statutory language guiding rule development to better address local government concerns.

 

What do the proposed rules mean for local governments, homeowners, and businesses within the MRCCA? Local governments will eventually need to update their plans and ordinances for this area. Most homeowners and businesses should see little if any change in their status.

MIDS Community Assistance Package and other Post Construction Guidance for Regulated MS4s

Posted By MNLA eNews, Thursday, June 19, 2014

Stormwater Professionals:


The MPCA would like to make you aware of two documents that have been placed on the MPCA Stormwater Web page to assist communities with the development of their post-construction stormwater management program.

 

The Minimal Impact Design Standards (MIDS) Community Assistance Package (CAP) contains ordinance guidance that will help communities who wish to implement MIDS.  The CAP can be found in the Minnesota Stormwater Manual: http://stormwater.pca.state.mn.us/index.php/Community_Assistance_Package

 

The second document is entitled “Technical Support Document for the Post-Construction Stormwater Management Conditions in the General Stormwater Permit (MNR040000) for Small Municipal Separate Storm Sewer Systems (MS4s)”. This guidance document is intended to help those communities that are regulated by the MS4 Permit to understand the options available for complying with the post construction stormwater management permit conditions (MCM 5). This document can be found at the following link: http://www.pca.state.mn.us/index.php/view-document.html?gid=17815

 

These documents can also be found on the MPCA MS4 Webpage under the Post Construction Stormwater Management section on the Guidance and BMPs tab.  http://www.pca.state.mn.us/sbiza7c

 

Question concerning these documents can be directed to Scott Fox at 651-757-2368 (Scott.Fox@state.mn.us) or Anne Gelbmann at 651-757-2384 (Anne.Gelbmann@state.mn.us).
