When it is deemed necessary by the city to install major transmission lines larger than are required to serve adjacent properties for domestic, industrial or fire protection purposes, the city may, pursuant to a written agreement between the city and the developer negotiated in advance to any work, compensate the developer for the difference in cost of the oversizing, if the extension is economically feasible for the city. Size of the water main to serve the abutting property shall be determined by the city engineer taking into consideration length of line, potential land use and fire flow requirements. (Ord. 5850 § 1, 2004; Ord. 5212 § 1 (Exh. H), 1999; 1957 code § 10.10.040.)
