Obtain a tree removal permit without an arborist

Recently due to windy weather, a huge branch (of a tree in our backyard) broke lose, fell and landed in our backyard, taking down our back fence. This poses significant risk for us.

In this case, would it be a valid reason to apply for the permit? Would it be possible to have it approved without an arborist? I checked the tree removal permit and it needed the "tree species" info, but I don't know what is the species of the tree...
