Talmage Triangle Raingarden

Concepts for Review

Metro Blooms Landscaper Mike Morrison presented three groups of concepts to the SECIA Environmental Committee for feedback from our Community. Please let us know what you like and what you don’t like about each group of concepts. From your feedback, we can design a final plan for the garden. Responses can be sent to Kathy@secomo.org or to the Talmage Crossing Garden email list.

Working with Minneapolis Public Works Metro Blooms’ Mike Morrison will use our feedback on a final Raingarden Landscape design for the vacated portion of 21st Ave. SE and Talmage.   

Please send your comments to Kathy Knudson (kathy@secomo.org) by Noon of Monday February 8th

Paved pathway with a seating wall on SW side. – Expanded Prairie Garden.Boulder outcropping wall at back of the raingarden separate from upper slope of expanded prairie garden.A dry creekbed would wind down the slope from the railroad tracks through two small rain gardens to empty into a large one.
Fence, privacy hedge and trees on east side.Stone pathway.There would be a 3 foot boulder wall on the upper edge of the rain garden.
Low shrubs between sidewalk and paved area. Mixed privacy hedge and a few trees along a fence along the east edge.A stepping stone pathway will cross over the dry creekbed.
Mixed privacy hedge along a fence on the east side would be lower near the sidewalk and include a couple trees on the upper slope.

Background

Decades ago a portion of 21st Ave. SE between the BNSF railroad tracks and Talmage Ave. SE was closed to through traffic. The asphalt was never removed and serves no purpose. It’s impervious surface runoff is a blight in our environment. SECIA and Community Gardeners have long sought changes. In 2010 Public Works Surface Waters and Sewers technician Paul Chellsen drafted a plan to divert storm water runoff from both the street and tracks into a large community rain garden there.  In 2019 the project was revived and put on the Minneapolis Public Works Schedule for 2021. Partners coming together to solve this environmental concern are Metro Blooms, Minneapolis Public Works Storm Water and Sewers, Community Gardeners and SECIA’s Environmental Committee. City Council support has also been crucial. 

Project Benefits

  • The garden will absorb stormwater preventing polluted runoff from reaching the Mississippi.
  • Native plants and wildflowers will provide habitat and sustenance for pollinators and other wildlife.
  • Aesthetically  it will transform an eyesore into a place of natural beauty.
  • Safety: The landscaping and fencing will separate the garden from the railroad tracks.
  • Community Gardening offers educational opportunities and Granite seating boulders can provide a place for neighbors and gardeners to rest and enjoy the a bit of nature or watch the trains from a safe distance.
  • A small Turfstone or Permeable paver area adjacent to sidewalk and other seating would allow wheelchairs.  
  • This amenity will be a sustainable landscape for future generations.
