§ 152.08 UTILITY AND DRAINAGE FACILITIES.
   (A)   Sewer and water.
      (1)   It shall be required that the owner or developer of the tract to be subdivided install, satisfactory sewer, and water lines which are necessary to serve such subdivision. Installation of the above shall be in accordance with the specifications of the village and under the direction and supervision of the Board of Trustees. Where adequate water and sewer lines are accessible within 1,320 feet of the final plat, connections to these lines shall be made. Water lines shall be looped according to specifications set by the Board of Trustees.
      (2)   The cost of providing this engineering service will be the responsibility of the owner or developer of the tract to be subdivided or by other agreement with the village. Design of municipal water mains and sanitary sewer lines shall conform to standards and guidelines approved by the Village Engineer.
   (B)   Sanitary sewer improvements. The following requirements shall govern sanitary sewer improvements.
      (1)   Where an adequate public sanitary sewer system is reasonably accessible in the determination of the Board of Trustees, public sanitary sewers shall be installed to adequately serve all lots, including lateral connections to the public system. Public sewer system extensions shall meet the requirements of the village standards and the State Department of Environmental Quality and the Department of Health and Human Services System. Combinations of sanitary sewers and storm sewers shall be prohibited.
      (2)   Where a public sanitary sewer system is not reasonably accessible, the subdivider may provide:
         (a)   A central treatment plant; provided that such central treatment plant is installed in accordance with the village and State Department of Environmental Quality and Department of Health and Human Services System requirements; or
         (b)   Lots may be served by individual disposal systems, if the provisions of § 152.09 are met.
      (3)   (a)   Where the installation of individual disposal systems is considered, the suitability of the soil for individual systems, the absorptive ability of the soil, surface drainage, ground water level, and topography shall be the criteria for determining whether or not the installation of individual systems is permissible. Criteria shall be in accordance with the requirements of the village and the State Department of Environmental Quality and Department of Health and Human Services System.
         (b)   Each lot so served shall be of a size and shape to accommodate the necessary length of tile field at a safe distance from and at a lower elevation than the proposed buildings. Such lot size and shape shall conform to the requirements of the zoning district in which they are located; provided that in no case shall said minimum lot be less than one acre in area where there is a public water supply available at the lot, and two and a half acres where there is not public water supply available.
         (c)   At least one percolation test shall be made for each lot area being platted, and each test shall be located in close proximity to the proposed individual sewage disposal unit, be numbered and its location shown on the preliminary plat. All percolation tests shall be performed in accordance with the requirements of the Board of Trustees.
   (C)   Drainage improvements.
      (1)   An adequate system for the drainage of all surface water within the area being subdivided, including ditches, pipes, culverts, intersectional drains, drop inlets, bridges, and other structures, shall be constructed by the developer. Such drains shall comply as to size with such requirements, conformable to good engineering practice, as the Board of Trustees shall prescribe; provided that such drains in no event shall be less than 12 inches in diameter. Cross drains shall be constructed to accommodate all natural water flow, be built on a straight line and grade, be laid on a firm base but not on rock and be of sufficient length to permit construction of streets and alleys to their required width and grades. Surface drainage pipes shall be laid with the spigot end pointed in the direction of the flow, and all ends shall be fitted and matched to provide tight joints and a smooth uniform invert.
      (2)   Such pipes shall be placed at a depth below the road bed that is sufficient to avoid dangerous pressure from impact, and the top, in no event, shall be less than one foot below the surface of the road bed.
      (3)   A culvert or other drainage facility shall in each case be large enough to accommodate potential runoff from its entire upstream drainage area, whether inside or outside the subdivision. The Village Engineer shall determine the necessary size of the facility, based on the provisions of the construction standards and specifications assuming conditions of maximum potential watershed development permitted by Chapter 151.
      (4)   The Village Engineer shall also study the effect of each subdivision on existing downstream drainage facilities outside the area of the subdivision. Where it is anticipated that the additional runoff incident to the development or the subdivision will overload an existing downstream drainage facility or flood existing development upstream, the Planning Commission may withhold approval of the subdivision until provision has the village made for the improvement of said potential condition in such sum as the Planning Commission shall determine. No subdivision shall be approved unless adequate drainage will be provided to an adequate drainage watercourse or facility.
      (5)   Subdivision proposals and other proposed new development be required to assure that all such proposals are consistent with the need to minimize flood damage; all public utilities and facilities, such as sewer, gas, electrical, and water systems are located, elevated, and constructed to minimize or eliminate flood damage; and adequate drainage is provided so as to reduce exposure to flood hazards so as to assure that all building sites are reasonably safe from flood hazards.
      (6)   Lots shall be laid out so as to provide positive drainage away from all buildings and individual lot drainage shall be coordinated with the general storm drainage pattern for the area. Drainage shall be designed so as to avoid concentration of storm drainage water from each lot into areas not designed to handle flood waters. Lot drainage plans shall conform to the drainage study required for submittal approval.
   (D)   Storm sewers and storm water drainage. Where an adequate public storm sewer system is available at the plat boundary, the village shall construct a storm sewer system and connect with such storm sewer line. If such a storm sewer system is not accessible, natural drainage channels with easement of adequate width shall be provided, as determined by the Village Engineer and approved by the Board of Trustees. Paved gutters or storm sewers shall be required if velocities are greater than specified in these regulations or cause destructive erosion. Storm drainage, including drain tile around basements, shall not be permitted to discharge into any sanitary sewer facility, but shall connect to an adequate drainage outlet.
   (E)   Culverts and bridges. Where natural drainage channels intersect any street right-of-way, it shall be the responsibility of the village to have satisfactory bridges and/or culverts constructed. Where culverts are required, minimum requirements shall be observed as follows.
      (1)   All culverts shall extend across the entire right-of-way width of the proposed street. The cover over the culvert and its capacity shall be determined by the Village Engineer. The minimum diameter of a culvert pipe shall be 18 inches. Depending on existing drainage conditions, head walls may be required.
      (2)   Driveway culverts shall have a minimum length of 20 feet, and a minimum diameter of 18 inches. The driveway culverts shall be laid so as to maintain the flow lines of the ditch or gutter. Head walls may be required.
   (F)   Solar access.
      (1)   In order to promote the conservation of energy through the use of both passive and active solar systems, streets in residential subdivisions should, where possible, have an east-west alignment. Lots intended for detached dwellings should be of sufficient width to allow the structure to be built with its longest axis running east-west.
      (2)   In order to allow the orientations of structures on the site so as to maximize potential solar gain, side lot lines should run as near to north-south as possible providing that the angle between the side of lot line and the street right-of-way line on a straight street or the tangent to a curved street shall not be less than 80 degrees.
      (3)   Any property owner or developer may grant or establish a solar sky-space easement to protect solar energy systems from shade. The easements shall be created in writing and shall be recorded separately or should be contained on the face of the plat. The easements shall run with the land.
   (G)   Erosion control. The subdivider shall be required to provide for the control of erosion of areas of the subdivision which are disturbed by grading operations by constructing temporary terraces on slopes, temporary silting basins, sod swales, and spillways, and whatever may be necessary to prevent erosion and damage to adjacent properties from surface drainage as approved by the village and the Village Engineer.
   (H)   Fire protection. Fire hydrants shall be provided by the village in all subdivisions with public water supplies. The hydrants shall be located between property lines and curbs with all outlets facing or parallel to the street. Hydrants shall be placed at the corners of all blocks and mid-block for blocks exceeding 800 feet in length. Hydrants shall also be required at the entrance and end of all cul-de-sacs exceeding 400 feet in length. The type of hydrant and control valves and the location of the hydrant shall be approved by the Fire Chief. The minimum size of any water line serving any hydrant shall not be less than six inches in diameter and should be circulating water lines. The size and location of water lines shall be approved by the Village Engineer and the Fire Chief.
   (I)   Electric, gas, and telephone improvements.
      (1)   Electric service and telephone service shall be provided within each subdivision. Gas service may be required where reasonably accessible. Whenever such facilities are reasonably accessible and available, they may be required to be installed within the area prior to the approval of the final plat. Telephone, electric, street lighting, and communications conductors may be installed underground at the option of the Board of Trustees.
      (2)   Overhead secondary utility lines, where installed shall be located at the rear of all lots.
      (3)   Whenever a sanitary sewer line and electric and/or telephone line is each placed underground in the same utility easement, the following provisions shall be applicable:
         (a)   The total easement width shall not be less than 15 feet; and
         (b)   The sanitary sewer line shall be installed within three feet of the easement, and the electric and/or telephone line shall be installed within three feet of the opposite side of the easement.
