A. The city drainage system consists of all rivers, streams, creeks, branches, lakes, reservoirs, ponds, drainageways, channels, ditches, swales, storm sewers, culverts, inlets, catch basins, pipes, head walls and other structures, natural or manmade, within the political boundaries of the city which control and/or convey stormwater through which the city intentionally diverts surface waters from its public streets and properties. The city owns or has legal access for purposes of operation, maintenance and improvements to those segments of this system which: 1) are located within public streets, rights of way, and easements; 2) are subject to easements of rights of entry, rights of access, rights of use, or other permanent provisions for adequate access for operation, maintenance, and/or improvement of systems and facilities; or 3) are located on public lands to which the city has adequate access for operation, maintenance, and/or improvement of systems and facilities. Operation and maintenance of stormwater systems and facilities which are located on private property or public property not owned by the city and for which there has been no public dedication of such systems and facilities for operation, maintenance, and/or improvement of the systems and facilities shall be and remain the legal responsibility of the property owner.
B. It is the intent of this chapter to protect the public health, safety and general welfare of all properties and persons in general, but not to create any special duty or relationship with an individual person or to any specified property within or without the boundaries of the city. The city expressly reserves the right to assert all available immunities and defenses in any action seeking to impose monetary damages upon the city, its officers, employees and agents arising out of any alleged failure or breach of duty or relationship as may now exist or hereafter be created. To the extent any permit plan approval, inspection, or similar act is required by the city as a condition precedent to any activity by or upon property not owned by the city, pursuant to this or any other regulatory ordinance, regulation or rule of the city under federal or state law, the issuance of such permit, plan approval, or inspection shall not be deemed to constitute a warranty, express or implied, nor shall it afford the basis for any action, including any action based on failure to permit or negligent issuance of a permit, seeking the imposition of money damages against the city, its officers, employees or agents.
