If the abutting property owner fails to trim the trees as required in this chapter, the City may serve notice on such property owner requiring said property owner to do so within five (5) days. If said owner fails to trim the trees within that time, the City may perform the required action and assess the costs against the abutting property for collection in the same manner as a property tax.
