| In new developments or when pavements are repaired or upgraded there are often opportunities to improve drainage, grading or pavement features to reduce the amount of salt needed during winter maintenance. Design changes may include, but is not limited to grading to keep meltwater away from trafficked areas, directing downspouts away from paved areas, installing windbreaks, avoiding flat grades that will eventually form depressions where water can puddle, creating designated snow storage areas that drain away from pavements and installing covers, heated pavements or pavement overlays that can be maintained with less salt (LSRCA, 2017). See below for more details. | | In new developments or when pavements are repaired or upgraded there are often opportunities to improve drainage, grading or pavement features to reduce the amount of salt needed during winter maintenance.
