Diseased trees are those with any form of decay or vegetation sickness that can be transmitted to other trees, plus those infected with insects to such an extent as to create a nuisance adversely affecting nearby persons or property. Such trees shall be removed immediately or shall be treated or sprayed to eliminate at once the risk of the decay or vegetation sickness being transmitted to other trees and to remove the insect nuisance situation.

The code official shall determine if a dead tree constitutes a safety hazard because of its proximity to the right-of-way, any building or structure, or to persons who use nearby premises. If the code official decides that a tree constitutes such a safety hazard, it shall be removed at the expense of the owner or operator responsible for maintenance of the premises on which it is located.

Within 30 days after casualty damage to any structure or exterior premises, the owner shall have taken the following steps:

• A. contracted for repair and restoration of damaged areas and removal of debris; and/or
• B. contracted for the demolition (as regulated by the Building Code of this city) and removal of any portions of the premises not to be repaired and restored, and also for removal of debris in connection therewith; and
• C. arranged for the contract work to be completed within 60 days from the contract date, except to the extent a delay is caused by weather, strikes, acts of God or other matters beyond the reasonable control of the owner and contractor.

The code official may extend these time periods to the extent he or she deems appropriate, but shall not be required to do so. Time is of the essence in repairing damage quickly so as to avoid detrimental impact upon persons and property.

Swimming pools shall be maintained in a clean and sanitary condition, and in good repair.

Private swimming pools, hot tubs and spas, containing water more than 24 inches (610 mm) in depth shall be completely surrounded by a fence or barrier not less than 48 inches (1219 mm) in height above the finished ground level measured on the side of the barrier away from the pool. Gates and doors in such barriers shall be self-closing and self-latching. Where the self-latching device is less than 54 inches (1372 mm) above the bottom of the gate, the release mechanism shall be located on the pool side of the gate. Self-closing and self-latching gates shall be maintained such that the gate will positively close and latch when released from an open position of 6 inches (152 mm) from the gatepost. An existing pool enclosure shall not be removed, replaced or changed in a manner that reduces its effectiveness as a safety barrier.

Exception: Spas or hot tubs with a safety cover that complies with ASTM F1346 shall be exempt from the provisions of this section.
