Salt reduction measures in Minneapolis

You can learn how Minneapolis uses best practices to lower chloride (salt) use in snow and ice removal.


Chloride (salt) is a permanent pollutant. It's harmful to aquatic and plant life. Help protect our freshwater and cut down on costs. Use less salt while still keeping safe conditions. Thank you to our salt stewards.

What this group does

This group is responsible for citywide snow and ice control on:

  • Streets
  • Alleys
  • Parkways
  • Some trails
  • Bikeways
  • Bridge sidewalks
  • some City owned sidewalks and pedestrian facilities 

De-icers used

We mainly use these de-icers and anti-ice methods:

  • Sodium chloride (NaCl) in the form of rock salt
  • Calcium chloride (CaCl2) for sidewalks and other pedestrian facilities
  • Magnesium chloride (MgCl2) on streets that comes in our treated salt.  


Employees take part in these trainings:

  • Formal Snowplow Operator Training (SPOT) with peer agencies or TMR trainers
  • APWA (American Public Works Association) trainings and workshops
  • Minnesota Local Training Assistance Program (LTAP) 
  • MPCA Smart Salting certification for employees and supervisors

TMR - Ramp restoration and repair 

This group manages the City parking ramps. They do sidewalk winter maintenance for police precincts and other City-owned sidewalks. 

TMR - Sidewalk inspections office 

Property owners are responsible for public sidewalks next to them in the right-of-way. This office hires contractors to clear properties that do not follow the rules. We require contractors to be MPCA Smart Salting certified.

TMR - Special service districts (SSD) 

This group maintains public right-of-way sidewalks. The City hires contractors and recovers the cost from the SSD.  We require contractors to be MPCA Smart Salting certified.
