Challenges to the Design of Runoff Management Practices in Cold Climates (Source: Caraco and Claytor,1997)

Climatic Condition BMP Design Challenge
Cold Temperatures

►Pipe freezing ► Permanent pool ice covered ► Reduced biological activity ► Reduced oxygen levels during ice cover

► Reduced settling velocities
Deep Frost Line

► Frost heaving ► Reduced soil infiltration

► Pipe freezing
Short Growing Season

► Short time period to establish vegetation

► Different plant species appropriate to cold climates than moderate climates
Significant Snowfall

► High runoff volumes during snowmelt and rainon-snow ► High pollutant loads during spring melt ► Other impacts of road salt/deicers

► Snow management may affect BMP storage
