The city shall not be required to provide sewer service to any property on the outside of the city limits. When, however, in the opinion of the city council, it would be in the best interest of the city and would promote the general welfare of its inhabitants to provide sewer service outside the city limits, the city council may authorize connections to property located outside of the city. All applications for sewer connections outside of the city shall be presented by the recorder to the city council and shall be approved only by the council. The council may, as a condition of approval, require a connection charge in excess of that required by Section 13.12.030. If the council finds that the cost of connection may reasonably be expected to exceed the connection charge provided for in Section 13.12.030. (Prior code § 4.110)
