Here is were I will disagree a little; first New England and the Northeast are extremely susceptible to extensive tree damage from events like this and will be going forward. You can trim around power lines all you will always of trees further away that can hit the lines. The storm winds ended at dark and the surveying of the damage really only took place in Yesterday. Today out of state crews will start to come in today (Florida Power & Light sending crews to Jersey yesterday) and set up staging and work. With the amount of damage a downtime of 3-4 days is not unreasonable.
I believe pre staging crews in this situation would be difficult due to damage up the NE Coast. What Eversource should be doing and FP& L has been doing for the past five years is swapping out a lot of the wooden poles for Cement poles, including high tension.
I have been involved in many restorations from IRene, Sandy, Matthew,Irma, and Michael and they all present different challenges.
