Abutting property owners may install and maintain underground lawn irrigation systems in the parking, provided that all related equipment, except necessary and direct connections from the water supply to the underground irrigation system, is located solely in an area within one foot of the street side of the sidewalk, or between five and six feet of the property line in areas where sidewalks are not installed. Abutting property owners acting pursuant to these provisions do so at their own risk and without any right, title, or interest in the parking or in the free use and enjoyment of the parking for the purpose allowed in this section. Abutting property owners acting pursuant to this section should take notice of the fact that installations in the parking will be subject to damage or destruction at any time that the City or a person with a utility easement deems it necessary to enter upon the parking for construction, maintenance, or any other purpose. Removal of underground lawn irrigation systems may be required at any time by the City.
