A. The subdivider shall be required to install all utilities in keeping with the installations of utilities surrounding the subdivision according to good engineering practices for each utility and subject to the approval of the city engineer. The utilities, mains, lines, services, and appurtenances shall be shown upon the tentative map or upon a special utility map, a copy of which, approved by the particular company or division involved, shall be filed with the city engineer for review and approval prior to the approval of the final subdivision map by the council. The final subdivision map shall show the location of all necessary easements located therein. The subdivider shall file with the city engineer security as required by the city engineer in accordance with the provisions for improvement security set forth in this article, assuring the installation of all utilities within such time as the city engineer may require and in any event within not to exceed one year after the date of the approval of the final map. The city engineer shall require that the installation of all utilities shall begin within ninety (90) days after the approval of the final map and shall proceed diligently to completion. The amount of time to be allowed shall be determined by the size and complexity of the subdivision and of the utility installations. No public utility facilities or appurtenances shall be installed in any public street, alley, easement, or right of way without a permit from the city engineer. The city engineer shall be given not less than two (2) days' written notice prior to the installation of any utility in a street, alley, or easement in order that inspections may be made.
B. Utility mains, lines, and services shall be brought to the curb line whenever their installation is in a public street and to the lot line of each lot whenever their installation is in a public alley or in an easement. Individual service installations shall not be required to the curb line or lot line for gas installations wherever such installations are not considered to be practical by the city engineer.
C. Inasmuch as all large tracts of land have been subdivided and most of the lots in the city are highly restricted and already improved, in all future subdivisions all utilities shall be brought underground to the subdivision and to each lot therein by the subdivider, and all installations, including all appurtenances, shall be entirely underground insofar as it is reasonable and practical to do so from the engineering standpoint, unless the city engineer finds that because of unusual conditions and circumstances on the subdivider's property or immediately surrounding it, such an installation would work an undue and unusual hardship or would he unnecessary and serve no useful purpose. Cost alone shall not be a decisive factor. (1962 Code § 10-903; amd. Ord. 75-O-1561, eff. 3-4-1975)
