Fall Environmental Risks: Preparing Your Property for Alberta’s Winter 🍂❄️

As temperatures drop and Alberta heads toward another winter, property owners and developers need to prepare their buildings and land for the challenges ahead. Fall is a critical window for preventative maintenance and environmental due diligence. Ignoring issues now can lead to costly problems once the snow flies and ground freezes.

Why Fall Preparation Matters

Unlike summer, when issues can be addressed quickly, winter conditions restrict site access and increase costs for remediation or repair. Preventive action in the fall minimizes liability, protects investments, and reduces risk to occupants and the environment.

Key Fall Environmental Risks

1. Drainage & Stormwater

• Fallen leaves and debris clog eavestroughs, catch basins, and storm lines, increasing the risk of ice damming and winter flooding.

• Poor drainage around foundations can lead to frost heave and water infiltration once freeze–thaw cycles begin.

  
  

2. Roof Integrity

• Even small leaks can become major issues under heavy snow loads. Inspect roofing membranes, flashing, and seals before the first snowfall.

• Consider professional inspections for flat-roofed commercial buildings, which are more vulnerable to water pooling and ice buildup.

  
  

3. Heating & Ventilation Systems

• Blocked vents and poorly maintained HVAC systems reduce indoor air quality and increase energy costs.

• Fall is the time to replace filters, clean ducts, and ensure exhaust systems are clear — especially important if wildfire smoke or summer dust has stressed the system.

  
  

4. Contaminant Migration

• Snowmelt in early winter can spread petroleum hydrocarbons, road salt, or other site contaminants into storm sewers or adjacent properties.

• A Phase I Environmental Site Assessment completed in the fall helps identify these risks before they become liabilities.

  
  

5. Site Access & Safety

• Properties under construction or redevelopment are especially vulnerable. Fall weather can leave exposed soils unstable, increasing erosion or runoff.

• Securing and stabilizing work sites before winter ensures compliance and reduces worker safety risks.

  
  

Fall Environmental Checklist ✅

• Clean and inspect all eavestroughs, storm drains, and drainage systems.

• Repair roof damage before snow and ice accumulate.

• Service HVAC and heating systems for winter operation.

• Seal gaps, cracks, and potential air or water entry points.

• Review environmental liability with a Phase I ESA or site inspection.

  
  

Stay Ahead of Winter Risks

Alberta’s climate doesn’t forgive neglect. Preparing your property in the fall protects both people and investments, ensuring you enter winter ready and resilient. For property owners considering transactions, renovations, or redevelopment, this season is the best time to complete environmental due diligence while conditions still allow.
