Nine Mile Creek must be put on a “low salt” diet.


Nine Mile Creek has too much chloride in it. The chloride comes from salt used in the winter on roads, parking lots, and sidewalks. The amount of chloride in the creek make the water unhealthy for the aquatic animals living there.

Tips for Using Less Salt

Person applying salt with a handheld spreaderIt is possible to reduce salt use while maintaining safe surfaces in the winter. Just follow these tips:

Shovel. Clear walkways before snow gets compacted or turns to ice. Apply salt only if needed.

Scatter. More salt does not mean more melting. Aim for 3 inches of space between salt granules. Use salt only where critical.

Switch. Common deicers don’t melt ice below  below 15° Fahrenheit (pavement temperature), so should not be applied. Instead, use a small amount of sand for traction when it is too cold.

Sweep. Clean up leftover salt and sand on dry pavement, so it doesn’t wash into the creek. Reuse it as needed.
