10.50.030 Subdivision – Improvement requirements – Utilities – Underground installation.
The public interest, safety and welfare require that utilities within undeveloped subdivisions shall be placed underground. The requirements shall be:
(1) Underground installation of utility facilities shall not include overhead facilities installed in order to provide emergency service, temporary poles and overhead lines used or to be used in connection with construction projects, service meters located at structures, surface-mounted connection boxes, surface-mounted transformers, pedestal-mounted terminal boxes, transmission lines and supporting structures, "through-feeders" of distribution lines and supporting structures that pass through a subdivision but provide no service to property located therein, wires for fire alarm and traffic signal installations, and structures used for street lighting facilities.
(2) The subdivider shall make all arrangements for the installation of underground utility facilities with the appropriate agency or utility. The cost of constructing new facilities underground or relocating existing aerial facilities underground shall be borne by the serving utilities, the owners of the real property to be served, and/or others requesting such underground services in accordance with the applicable filed tariffs, the accompanying rules and regulations of such utilities as approved by the Washington Utilities and Transportation Commission, and the published policies of the respective municipal and/or other utilities; provided, however, that such published policies, as distinguished from approved tariffs, are not in conflict with presently enacted or hereafter enacted or amended applicable city ordinances.
(3) Easements for the underground installation of utility facilities and, where necessary, for existing overhead transmission and existing through-feeder distribution facilities, shall be provided by the subdivider and shall be set forth in the preliminary plat and final plat to serve the subdivision and each lot therein. The lot easements shall be a minimum of sixteen feet in width and, when possible, centered on side or rear lot lines, or eight feet on the property side of front lot lines.
(4) Where underground utilities are installed within a subdivision, all lot owners shall be served only by those underground facilities.
(5) Street lights shall be at locations and on poles authorized by the city providing illumination approved by the public works director. At a minimum street light shall be installed at all street intersections and at no greater spacing than one hundred seventy-five feet apart and at the ends of cul-de-sacs. In the event that the city or subdivider determines that poles other than wood poles shall be used for street lighting, the cost of such poles shall be in accordance with the policies and applicable tariff provisions of the utility involved. Additionally, all street lighting must meet the requirements of Chapter 7 of the City of Selah Design, Construction Standards, and Specifications Manual for Public Works Improvements as adopted in Section 13.01.010.
(6) In addition to the foregoing, the utilities in a subdivision shall conform to the following specifications and standards:
(A) All water and sewer lines shall be designed in accordance with the comprehensive water and sewer plans of the city of Selah, and Chapters 4 and 5 of the City of Selah Design, Construction Standards, and Specifications Manual for Public Works Improvements as adopted in Section 13.01.010.
(B) Installation of all water and sewer lines and storm drains shall be in accordance with the standards set forth in Section 10.50.021 and Chapters 4, 5 and 6 of the City of Selah Design, Construction Standards, and Specifications Manual for Public Works Improvements as adopted in Section 13.01.010, and under the supervision of the public works director.
(C) After grading is completed and approved, but before any base is applied, all of the underground utilities and all service connections shall be installed, completed and approved throughout the length of the road and across the flat section according to city's standards.
(D) The water distribution system shall also be designed and installed in a manner that is satisfactory to the fire department of the city at the subdivider's expense.
(E) A storm drain system for the subdivision shall be constructed in such a manner as to prevent erosion or the development of safety hazards. All storm water runoff from development shall be retained on site. Storm water runoff calculations and drainage facilities sizing calculations must be prepared by the developer's registered professional engineer and transmitted to the city for review. The development's storm drainage facilities must comply with the city of Selah storm water management plan, and Chapter 6 of the City of Selah Design, Construction Standards, and Specifications Manual for Public Works Improvements as adopted in Section 13.01.010.
