? Winter 2004 -2005 ? Relatively normal to slightly above average temperatures every month except March with slightly below average temperatures ? 21 event days (more than 0.5” snow) ? 48.2 total inches of snow was 3.7 inches less than normal for season ? Winter 2005 -2006 ? Above average temperatures every month except December with slightly below average temperatures ? 18 event days (more than 0.5” snow) ? 37.9 total inches of snow was 14.0 inches less than normal for season

# Preliminary Summary of 2005 -

2006 Conservation Practices

C = (145,948)/(145,948 + 6,365) = 0.958 This reduced our Permit Requirement by 4.2%
