(A) Any tree growing in any public street, sidewalk, parkway, or along the line of any public sewer or sewer lateral connection is hereby declared to be a public nuisance and may be removed by the Director of Public Works if he finds:
(1) That such tree endangers the security or usefulness of any such public sewer or sewer lateral connection, and
(2) In the case of an existing sewer lateral connection, that such existing sewer lateral connection is reasonably impervious to street tree roots.
(B) If any such existing sewer lateral connection is found not to be reasonably impervious to street tree roots, then the Director of Public Works may defer the removal of such tree until such time as the property owner, at his own cost, replaces the existing sewer lateral connection with another that is reasonably impervious to street tree roots.
