PUBLIC WORKS Overuse of winter de-icers is harming Minnesota’s lakes, wetlands, streams, and groundwater, and just one teaspoon of de-icing salt can permanently pollute five gallons of water. Created by the Hennepin County Chloride Initiative and Metro Watershed Partners, the Low Salt, No Salt Minnesota initiative helps communities maintain winter safety while reducing harmful chloride pollution. Chlorides are difficult to remove once they enter the environment and can damage infrastructure, landscaping, and flooring; plus salt also harms fish and other aquatic life, degrades drinking water sources, and contributes to blue-green algae blooms. Research from the University of Minnesota shows that about 75% of de-icer stays where it’s applied, where it can damage soil and prematurely age pavement and concrete. When temperatures are very cold, salt is often ineffective, making alternatives such as sand or chicken grit a better choice. Chicken grit provides traction without harming the environment and is easy to sweep and reuse. Use salt wisely this winter: Shovel early to prevent snow from turning to ice Use sand or chicken grit for traction when it’s below 15°F Apply salt only where needed—one coffee cup covers a 20-foot driveway Using less salt helps keep walkways safe, saves money, and protects Lake Elmo’s water resources.

The goal of this research is to improve conservation by developing drought-resistant grass that requires less fertilizer and irrigation water, while still maintaining an attractive lawn appearance. The UofM has installed the test plot, a temporary irrigation system, and public informational signs, and will maintain the grasses for the first year. The university will cover the cost of irrigation water, and performance evaluations will occur in 2026 and 2027. Lakeelmo.gov
