*Seasonally closing parking areas: many parking lots have areas that are infrequently used outside of the holiday shopping period. These areas can be closed and not maintained through much of the winter season, reducing both the effort and amount of salt required.

*Shaded Canopies: With roof canopies over major pedestrian walkways and entrances from parking lots to building enclosures, little to no snow or ice will fall in these high-traffic areas, resulting in reduced salt application. Consideration should be taken for the runoff generated from the canopy stormwater or snowmelt when weather begins to warm to limit the potential for of ponding/refreezing on the walkway.

*Conductive Pavement on Walkways/Entrances: Conductive pavements consist of electrically and thermally conductive materials mixed with the dielectric aggregates typically found in standard asphalt and concrete pavements. Once connected to a power or heat source, these pavements conduct electricity and emit heat to pavement surfaces, melting ice and snow with constant and uniform heat.

*Brine holding tanks: Collection of first flush (high chloride concentration) melt water runoff from a salt induced snowmelt (as opposed to rain and temperature induced snowmelt) has the potential to be beneficial if captured and reused as an anti-icing or pre wetting solution. In order to collect the first flush runoff, an electronically actuated valve controlled by an electrical conductivity sensor would be installed at the desired conveyance point to divert and collect the high chloride concentration runoff into a brine holding tank. The brine holding tank would be placed below ground and a pump could be connected to pump the brine solution into an anti-icing tank or directly used to pre-wet rock salt.
