  7. The nature and extent of the bodily waste odor, unsanitary condition or noise created by the animal;

  8. The manner in which the animal had been maintained by its owner;

  9. The presence or absence of any provocation for the habitual howling, yelping, barking, trespassing or other noise;

Such arrangements shall be agreed to in writing between the owner and the hearing officer prior to and as a condition of release of the animal to its owner. If such arrangement is not made and executed within 30 days from the date of impoundment, then the animal may be considered abandoned and may be handled in the same manner as any other unclaimed stray animal.

If such further assurances are not made and executed within 30 days from the date of impoundment, then the animal may be considered abandoned and may be handled in the same manner as any other unclaimed stray animal.

E. The owner of the animal that has been impounded pursuant to this section shall be responsible for all costs of impounding the animal, including but not limited to, daily impoundment fees and any costs incurred in providing care and maintenance to the animal.
