The Impact of Salt on Infrastructure and Environment

The use of salt for deicing is widespread due to its effectiveness and low cost. However, this common practice poses significant risks to both parking lot infrastructure and the surrounding environment.

Damage to Concrete and Asphalt

Salt is known to cause damage to concrete and asphalt surfaces over time. When salt is applied to ice, it lowers the freezing point of water, causing the ice to melt. However, as the temperature drops, this water can refreeze, leading to a freeze-thaw cycle that can crack and deteriorate pavement. In fact, studies have shown that salt can reduce the lifespan of concrete surfaces by up to 50%, leading to increased maintenance costs and disruption to parking lot users.

Environmental Consequences

The environmental impact of salt usage is equally concerning. When snow or ice melts, the salt is washed away into storm drains, rivers, and lakes, leading to increased salinity in freshwater bodies. This growing salinity can harm aquatic ecosystems, disrupt plant growth, and contaminate drinking water sources. Furthermore, high salt concentrations can impede the ability of soil to hold water, impacting vegetation in areas surrounding parking lots.

The Need for Change

Given these impacts, the need for more sustainable winter maintenance practices is clear. Property managers and urban planners are now tasked with finding alternative methods to ensure safety during winter months while also protecting valuable infrastructure and the environment. This is where innovative parking lot design and maintenance strategies come into play.

Innovative Solutions for Safer Winter Parking Lots

To address the issues posed by salt application, four key strategies have emerged. These strategies aim to enhance parking lot design and maintenance, ensuring safety and accessibility during winter while minimizing environmental impact.

Effective Grading and Stormwater Collection

Proper grading and effective stormwater collection play a crucial role in reducing the need for salt application in winter maintenance.

  • Minimizing Ponding and Refreezing:

Many winter maintenance issues arise from poor grading, leading to ponding and refreezing of meltwater. Proper grading can convey meltwater quickly and directly to stormwater features, preventing it from freezing and reducing the need for additional salt application.

  • Recommending Slopes:

The guidelines recommend maintaining slopes between 2-4% to minimize the formation of depressions where water can accumulate and freeze. Additionally, ensuring sufficient compaction of granular base materials is vital to maintaining consistent slopes.

  • Stormwater Features:

Directing meltwater towards strategically placed stormwater collection infrastructure, such as catch basins and vegetated swales, helps prevent salt application in high-traffic areas that are also pathways for runoff.

Snow Pile Storage Location

The placement of snow piles is another critical factor in winter maintenance. Strategic snow pile placement helps ensure that high-traffic areas remain safe from meltwater refreezing, while also taking advantage of sunlight to maximize melting.

  • Ideal Placement:

Snow piles should be located in low-traffic areas, along the outer edges of parking lots, and down-gradient from high-traffic areas. By situating them where they can receive abundant solar radiation, ideally away from tree canopy and facing south, the melting process is accelerated.

  • Wind Patterns:

Understanding the wind patterns of the parking lot is crucial. Snow piles should be placed where they are least likely to cause snow drifts, preventing obstruction to drivers and pedestrians.

  • Visual Obstructions and Signage:

To ensure safety, it’s important to prevent visual obstructions to drivers and pedestrians. Additionally, clearly marking snow piles with signage informs contractors of where to place snow, improving overall organization and efficiency.

Sidewalk Design and Pedestrian Flow

With a significant percentage of salt applied to parking lots being used on sidewalks, effective sidewalk design is essential to reducing overall salt usage while ensuring pedestrian safety.

  • Width and Location:

Sidewalks should be designed to be wide enough to accommodate pedestrian flow, especially in busy commercial areas. They should be located adjacent to parking spaces to minimize the risk of pedestrian accidents.

  • Material Choice:

Choosing the right materials for sidewalks can also influence salt application needs. Permeable materials not only reduce runoff but also allow for better drainage, minimizing ice formation and the subsequent need for salt.

  • Integration with Landscaping:

Integrating sidewalks with landscaping features can further enhance pedestrian safety and comfort. Vegetated areas can absorb water, reducing runoff and ice formation, while trees provide shade that can slow down the melting process during warmer months.

Eco-friendly Deicing Alternatives

Alongside smart design strategies, the adoption of eco-friendly deicing alternatives is crucial for sustainable winter maintenance.

  • Plant-based and Organic Options:

These alternatives are less harmful to both infrastructure and the environment compared to traditional salt applications. For instance, deicers made from plant materials or organic substances have been shown to effectively lower freezing points without causing corrosion or contributing to soil salinity.

  • Brine Solutions:

Pre-treated brine solutions, which contain a mixture of salt and water, can be used before a storm to prevent ice from bonding to surfaces. This method minimizes the amount of salt needed during and after snow events, while also reducing overall salt runoff into waterways.

  • Innovative Technologies:

Emerging technologies in deicing are also showing promise. For example, heated pavement systems, although costly, can prevent ice formation without using salt. Additionally, the use of sensors to monitor temperature and moisture levels can optimize deicing operations, ensuring that salt is only applied when necessary.

Conclusion

Incorporating these innovative design strategies and eco-friendly deicing alternatives provides a pathway for property managers and urban planners to ensure safe winter parking while mitigating environmental impact. By prioritizing sustainability, the future of winter maintenance looks promising, paving the way for safer and greener winters for all.
