Minimal Impact Design Standards (MIDS) - What a difference two years makes!

Posted By MNLA eNews, Wednesday, December 23, 2015

From Minnesota Pollution Control Agency Weekly Digest Bulletin

Since the MIDS project was completed two years ago, several entities using the work products shared their uses and successes at the Water Resources conference held on October 14, 2015 at the St. Paul RiverCentre.

  • John Hanson, Valley Branch Watershed District Administrator, presented on how the District is using the MIDS performance goals. Valley Branch is the first organization to adopt the MIDS performance goals.
  • Representing the city of Blaine, a regulated MS4, Jim Hafner said the city has adopted MIDS to meet their MS4 requirements and that the city, along with the two watershed districts they are in, use the MIDS calculator for all new projects.
  • Mike Isensee, from the Middle St. Croix Water Management Organization, announced they had received a Clean Water Land and Legacy grant to work with up to 10 communities in the watershed to adopt MIDS.
  • Michele Wigern, speaking on behalf of the Fairbault Soil and Water Conservation District, said the District uses the MIDS calculator and best management practices in the stormwater manual for guidance and grant applications.
  • Jay Michels, a consultant representing Emmons and Olivier, said the organization has taken MIDS on the road to other states and to Canada.
  • MIDS was also recently included in the Environmental Quality Board's Water Policy Report. Goal 2 of the report is to manage our built environment to protect water and includes adoption of the MIDS work products as the system change that is needed to manage runoff.

Find out how other watershed districts, watershed management organizations and cities have adopted MIDS in various ways on the Community Assistance page.

If you have adopted MIDS into your programs, please contact Anne Gelbmann (anne.gelbmann@state.mn.us) and your organization will be listed in the stormwater manual.

Despite treatment, 16 zebra mussels confirmed in Christmas Lake

Posted By MNLA eNews, Friday, December 4, 2015

From the Minnesota Department of Natural Resources

Despite aggressive treatment, 16 zebra mussels have been confirmed across a wide area of Christmas Lake in Shorewood, according to the Minnesota Department of Natural Resources. The spatial distribution and age of the mussels found indicate that a reproducing population is established and further treatment would not be effective. While the agencies involved in the treatment project are disappointed, they say the information gained from the effort was worthwhile and will be used for future treatments in other bodies of water.

Although no zebra mussels were found in extensive dive searches of the lake as recently as last month, a lake service business reported finding one zebra mussel on a dock earlier this week. Divers with the DNR and the Minnehaha Creek Watershed District found the invasive species on docks and boat lifts in an inspection that followed the initial report.

“These findings demonstrate the challenges of monitoring and treating zebra mussels,” said Keegan Lund, DNR invasive species specialist. “None of these newly discovered zebra mussels were found in the area of Christmas Lake that was treated earlier this year,” Lund noted, “but most of those we found were juveniles. That tells us reproduction has occurred and this population is established. Because zebra mussels are scattered across the lake and reproducing, current management options are not feasible.

“We’re working with the Christmas Lake Homeowner’s Association, the Minnehaha Creek Watershed District, and the Minnesota Aquatic Invasive Species Research Center to continue our assessment,” Lund said. “What we learn will inform future rapid response treatments and pilot projects. The DNR appreciates the valuable contributions all partners have made to this project.”

The first zebra mussel in the recent Christmas Lake discoveries was found on a dock by a lake service provider who was removing the equipment from the water. This find is a reminder that this time of year, when water-related equipment is being removed, is an especially important time to check docks, lifts and other equipment for zebra mussels. By law, docks and lifts must also dry for at least 21 days before putting them into another body of water, whether they are coming from an infested lake or not.

“There is a common misconception that zebra mussels ‘are everywhere’ and that their spread is inevitable. The reality is, zebra mussels have been confirmed in less than two percent of Minnesota lakes, and more Minnesotans than ever before know and follow invasive species laws,” Lund said. “People spread zebra mussels, and people can prevent the spread.”

Irrigation Sprinkler Standard Gaining Adoption

Posted By MNLA eNews, Friday, December 4, 2015

Last year, a national consensus committee completed a four-year process and published the first-ever landscape sprinkler product standard. In its November E-Times, the Irrigation Association included the following summary of important areas where the standard is growing in acceptance.

The ASABE/ICC 802-2014 Landscape Irrigation Sprinkler and Emitter Standard is now a mandatory requirement in the revised California Model Water Efficient Landscape Ordinance. MWELO has been adopted by the California Building Standards Commission, and manufacturers are having their products tested for compliance. This standard is also a requirement in the International Association of Plumbing and Mechanical Officials’ Green Technical Supplement. It may also be included in the National Green Building Standard, the Green Building Initiative and the 2017 version of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers 189.1 High Performance Green Buildings standard.

As products are released that meet or exceed the standard, irrigation specifiers could begin to require these products on designs, thereby making new irrigation systems more water-efficient (at least from a component standpoint). Information about the ASABE/ICC 802-2014 Landscape Irrigation Sprinkler and Emitter Standard:
