(b) Water.
(1) Proposed new water mains in existing roads or streets shall generally be located on the north or east side of the existing road or street outside of the existing or proposed pavement area.
(2) The layout of a new water main system and appurtenances shall be approved by the engineers of the agency, who will supply the water to the system, either directly and/or indirectly through the Greater Cincinnati Water Works.
(3) All materials used and the installation of those materials in the line shall be in accordance with the specifications and charges for inspection of the agency, who will supply the water to the main and/or the Greater Cincinnati Water Works.
(4) Fire hydrants shall be placed at approximately 400-foot intervals.
(5) There shall be four (4) control valves at each cross intersection and three (3) control valves at each "T" intersection. All main line control valves shall be housed in a standard brick valve chamber. Fire hydrant control valves may be housed in a standard valve box.
(6) Wherever it is possible, proposed mains shall connect to existing mains. Dead-ends shall not be permitted where it is possible to obtain a closed circuit to existing mains.
(7) The size of water mains to be installed in a new system will be determined by the water supply agency and/or the City Engineer, and installed in accordance with the City-County water contract.
(8) All water service branches from the water mains to the property line will be installed by the water supply agency and/or its agent, upon application and payment of the tapping charge.
(9) Upon the approval of a water main plant showing all of the construction details of design, etc., the Greater Cincinnati Water Works will make a preliminary estimate of cost of construction for the water main. The subdivider then shall make a formal request for permission from the City to construct the water main and appurtenances at their own cost and expense and in accordance with the plans, specifications, City-County water contract and estimate on file in the Greater Cincinnati Water Works. The subdivider shall agree to pay to the City two percent (2%) of the estimated cost for overhead and maintenance charge. He shall agree in the request to save the City and all its representatives harmless from all suits, actions or claims of any character brought on account of any injuries or damages sustained by any person or property in consequence of any neglect in safeguarding the work or through the use of unacceptable materials in the construction of the improvement or on account of act or omission by the subdivider, or their agents.
(c) Gas Mains. All new gas service branch lines shall have a shut off valve at the property or curb line.
(d) Sanitary Sewers. Where a public sanitary sewer is within reasonable access of the subdivision as determined by the number of lots, the distance from and capacity of existing sewer lines, and the topography, each lot therein shall be provided with a connection to such sanitary sewer. All sewers shall be designed and constructed in accordance with Metropolitan Sewer District (MSD) standards.
(e) Storm Drainage and Storm Water Detention.
(1) The drainage system for each subdivision shall be designed based on the City's current adopted design criteria for storm drainage.
(2) Where water detention is required to meet these standards, the water detention area shall not be part of any street.
(3) The design of the drainage system, including pipe and culvert size, and the design of the water detention area, shall conform to specifications as contained in the City's standard drawings.
(4) The following plat language shall be included on subdivision plats with regard to addressing storm water drainage and maintenance.
A. Private Drainage Easements. The City of Sharonville and Hamilton or Butler County, as applicable, does not accept private drainage easements shown and or referenced on this plat and the City of Sharonville and Hamilton or Butler County, as applicable, are not obligated to maintain or repair any channels or installations in said easements. The easement area of each lot and improvements in it shall be maintained continuously by the owner of the lot, and within these easement areas, no structure, planting or other material shall be placed or permitted to remain which may obstruct, retard, or change the direction of the flow of water through the drainage channel in the easement areas.
B. Private Drainage Easements Between Lots. Unless otherwise designed on the record plat, a ten (10)-foot-wide private drainage easement shall exist along all common lot lines, the common lot line being the centerline of said easement for the construction and maintenance of storm drainage and associated appurtenances.
(f) Underground Utility Distribution and Communication Facilities. The installation, construction, and expansion of electric, telephone, cable television and/or all new services for subdivisions shall generally be placed underground subject to the following conditions and exceptions:
(1) Transmission lines are exempt from this section. Transmission lines are defined as those lines constructed between generating stations and substations.
(2) Underground utilities shall serve the subdivision within or along the right-of-way of existing or proposed public streets, provided that prior to installation of such facilities, the subdivider pays the utility companies' schedules and/or associated charges and gives written commitment to pay the utility company for the cost of any relocation of such facilities and to provide all easements necessary for relocation and for any extensions. The subdivider shall provide necessary easements to the utility companies at no cost.
(3) All service lines connecting the customer's service within the utility company's underground distribution lines shall be installed underground to connection points on the distribution facilities determined by the utility company. The customer's service line shall be installed by the subdivider or customer, except for communications service lines. The actual connection to the utility company's facilities shall be made by the utility company. Underground electrical wiring shall be a minimum of thirty (30) inches below final grade and shall be bedded in and covered by a minimum of four (4) inches of sand, or shall be protected by commercially available plastic tile, such as "core-flo" or an approved equal.
(4) Installation of pad mounted transformers and communication interconnection cabinets are required and nothing in this section shall be construed as requiring the installation of this equipment underground. The use of underground transformers shall not be permitted. Prior to paving any street, the developer shall install, at its own cost, acceptable separate conduit cross-overs for electric and communication facilities at locations specified by the utility company.
(5) Temporary overhead services of electric and telephone utilities shall be allowed, provided that all permanent electric, telephone and cable television services within and adjacent to a new subdivision or commercial and industrial use shall be underground. For purposes of this section, "temporary overhead service" means:
A. Service necessary for immediate public convenience and necessity and constructed to serve only on an interim basis until permanent underground services can be installed; or
