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 |
