Prioritize the List n n n Identify the top five roads that need to be cleared ASAP. Keep an “aging” list. Consider dead end streets (only one way in or out) Main roadways (major problem to traffic flow) Primary access for emergency vehicles? Level of difficulty in clearing (easier ones first)
Fax List to Electric Utility n n n Fax is usually preferable to email Put road location clearing in order of preference Call to be sure that list was received Ask for ETA of linemen crew(s); give location for initial contact within the municipality Don’t leave the line crew alone for a minute!

Right Spot for the Right Tree n Both the trees and the utility pole wiring can change over the years
Severe Pruning – can it actually make it worse? n n Tree can be left in a poor state of health Radical pruning can leave the tree structurally unbalanced Many downed power lines are the result of the whole tree being uprooted Maybe the right place for the tree is where it is, but the power lines should go underground
