Customers and the public want safe parking lots and sidewalks. Understanding the materials, weather and application rates, provide a head start on controlling icy, slippery parking lots, and sidewalks.

Clean and neat parking lots and sidewalks are important to the public. By using less material and increased winter sweeping, pedestrians will track less material into buildings and there will be less damage to flooring. Proper snow storage makes debris removal in the spring easier. Covered storage of deicers will reduce loss of material, protect water, and is more aesthetic. Using BMPs and lower application rates will keep parking lots and sidewalks looking neat.

Customers also want affordable snow and ice control. The use of sophisticated chemicals and equipment may require a larger budget up-front; however, these costs can be balanced by reduced on-going costs. Reducing the need for sweeping, floor and rug maintenance, parking lot striping, and snow and ice maintenance time will allow for cost savings.

*Chloride is virtually a permanent pollutant that does not degrade and cannot be removed from surface waters. Once in the water, it continues to accumulate in the environment over time.

*Salt water is heavier than freshwater and may sink to the bottom of lakes. This may cause chemical stratification of the lake and loss of or changes in lake turn over ([http://www.lrrb.org/media/reports/200842.pdf Stefan et al. 2008]).

*About 75% of Minnesotans rely on groundwater for drinking water. The MPCA has found 30% of the shallow monitoring wells, often found in urban areas, have exceeded the state standard for salt levels.

*The average salt use in the TCMA based on purchasing records is 349,000 tons per year ([https://conservancy.umn.edu/bitstream/handle/11299/115332/pr503.pdf?sequence=1 Sander et al. 2007]).

The Winter Parking Lot and Sidewalk Maintenance Manual delivers practical advice to those managing parking lots and sidewalks. The manual helps to make proactive, cost-effective, environmentally conscious choices in winter parking lot and sidewalk management. This knowledge will provide the opportunity to become a leader in the industry by operating more efficiently and reducing environmental impacts. A single approach will not work for the range of conditions Minnesota experiences; different strategies are needed for different regions and different weather conditions. We encourage continuing to test, document, and refine the practices from this manual.

The manual was developed in 2006 and underwent revisions in 2010 and 2015. The information in the manual has been reorganized and reformatted for inclusion in the Minnesota Stormwater Manual. As a result, the manual was organized into several pages that address specific topics and are linked to each other. These pages can also be viewed as a single page. The 2015 Winter Parking Lot and Sidewalk Maintenance Manual can also be accessed as a pdf document.
