yes, "tree canopy" is valid--but it usually used to describe the tops of trees in a forest.

a tree lined street,allée, or driveway is more often called a 'bowery'.
NYC's 'bowery' (a continuation of lower half of 2nd Avenue) got its name because it was originally the driveway to the country estate of retired Governor Styvatston(sp?). the estate was planned around the native trees, and right from the beginning had a bowery, and was called The Bowery.

in the 1930, the area was rather seedy, and most people today are more family with 'The Bowery Boys' (a movie series of films about a bunch of borderline juvenile delinquents,) or from the term 'bowery bum' (aka an alcoholic).
