(1993 Code Ch. 155 Appx. A.)
§ 6    STREET BASE COURSE.
   The developer has the option of using any of the following base courses, based on recommendations of the Director of Public Safety and Service as to soil and traffic conditions: aggregate, bituminous aggregate, asphaltic concrete, waterbound macadam, portland cement concrete, or equally suitable base course. Thickness shall be determined by the Director of Public Safety and Service, based on the physical properties of the base course used and the physical properties of the roadbed.
(1993 Code Ch. 155 Appx. A.)
§ 7    STREET SURFACE COURSE.
   On the expiration of the established maintenance period for the base course, the surface course shall be constructed using either asphaltic concrete, bituminous mix, or portland cement concrete. Specific material and thickness recommendations shall be determined by the Director of Public Safety and Service based on traffic conditions.
(1993 Code Ch. 155 Appx. A.) 
§ 8    PORTLAND CEMENT CONCRETE PAVEMENT.
   If the subdivider elects to construct streets totally out of Portland cement concrete or if such pavement is required by the Director of Public Safety and Service, thickness of seven inches for all streets shall be required. The City Planning Commission may require pavement of greater thickness, on the recommendation of the Director of Public Safety and Service, based on his evaluation of the subgrade, traffic, and wheel load conditions.
(1993 Code Ch. 155 Appx. A.) 
§ 9    FULL-DEPTH ASPHALT PAVEMENT.
   If streets are to be constructed out of full-depth asphalt an asphalt pavement in which asphalt aggregate mixtures are used for all courses above the subgrade, careful inspection of the subgrade may be necessary, to determine pavement thickness. In no case shall the thickness be less than that  specified in Section 913.07.
(1993 Code Ch. 155 Appx. A.) 
§ 10    STREET CURBS AND GUTTERS.

§ 12    WATER SUPPLY IMPROVEMENTS.
   (A)    The following requirements shall govern water supply improvements.
      (1)    Where a public water supply is reasonably accessible or required because of pollution problems, in the determination of the Commission, the subdivision shall be provided with a complete water distribution system, including a connection for each lot and appropriately spaced fire hydrants. Public water distribution and public wells systems shall meet the requirements of the Ohio Department of Health and cited in Ohio R.C. 3701.18 through 3701.21.
      (2)    Where public water supply is not available or not required, the subdivider shall supply acceptable evidence of the availability of water. The subdivider may be required to make one or more test wells in the area to be platted if such evidence is deemed not acceptable. Copies of well logs which are obtained shall include the name and address of the well driller and shall be submitted with the plat to the Commission.
   (B)    Individual private wells shall be located at least 25 feet from property lines; 100 feet from all septic tanks; 100 feet from all tile fields and other sewage disposal facilities; 40 feet from streams, lakes, ponds, and ditches; 20 feet from all cast iron sewer lines; and 100 feet from any vitrified sewer tile lines, and shall not be located within any areas of flooding. As a precaution against seepage, a watertight seal shall be provided around the well casing. Minimum lot sizes shall be in accordance with the requirements of the zoning district in which the subdivision is located. In all cases where it has been determined that individual water supplies from private wells are not feasible, a public water distribution system shall be required.
(1993 Code Ch. 155 Appx. A.)
§ 13    FIRE PROTECTION.
   (A)    Fire hydrants with 2-1/2-inch outlets and one large pumping connection shall be provided by the subdivider in all subdivisions with public water supplies. The hydrants should 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 at midblock 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.
   (B)    The type of hydrants and control valves and the location of the hydrant shall be approved by the Fire Chief. Water lines serving any hydrant shall be circulating and shall be not less than six inches in diameter. The size and location of water lines shall be approved by the Director, the Fire Chief, and the Ohio Inspection Bureau.
(1993 Code Ch. 155 Appx. A.)
§ 14    SANITARY SEWER IMPROVEMENTS.
   The following requirements shall govern sanitary sewer improvements:
   (A)    Where an adequate public sanitary sewerage system is reasonably accessible, in the determination of the Commission, public sanitary sewers shall be installed to adequately serve all lots, including lateral connections to the public system. Public sewerage system extensions shall meet the requirements of the Ohio Department of Health and City standards. Combinations of sanitary sewers and storm sewers shall be prohibited.
   (B)    Where a public sanitary sewerage system is not reasonably accessible, the subdivider may provide a central treatment plant for the group, provided that such central treatment plant is installed in accordance with State and City Board of Health requirements.
   (C)    Where a public sanitary sewer system is not reasonably accessible and a central treatment plant for the group is also not feasible, individual on-site septic tank systems may be utilized upon approval of the City Health Department and City Planning Commission.
      (1993 Code Ch. 155 Appx. A.)
§ 15    DRAINAGE IMPROVEMENTS.
   The subdivider shall construct all necessary facilities including underground pipe, inlets, catch basins, or open drainage ditches, as determined by the Director of Public Safety and Service, to provide for the adequate disposal of subsurface and surface water and maintenance of natural drainage courses. The velocity of flow in an open ditch shall not exceed four feet per second in soil ditches or six feet per second in turf gutters. Paved gutters will be required if velocities of flow are greater than those specified or if it is otherwise likely that destructive erosion will result. Drainage ditches shall not be permitted to discharge into any sanitary sewer facility.
(1993 Code Ch. 155 Appx. A.) 
§ 16    STORM SEWERS AND STORM WATER DRAINAGE.
   Where an adequate public storm sewer is available at the plat boundary, the subdivider 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 easements of adequate width shall be provided, as determined by the City Engineer and approved by the Commission. Paved gutters or storm sewers shall be required if velocities of flow are greater than specified in § 15 above or causes 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.  (1993 Code Ch. 155 Appx. A.)
§ 17    OVER-SIZED AND OFF-SITE IMPROVEMENTS.
   The utilities, pavements, and other land improvements required for the proposed subdivision shall be designed of over-size or with extensions provided to serve nearby land which is an integral part of the neighborhood service or drainage area as determined by the Director of Public Safety and Service.
(1993 Code Ch. 155 Appx. A.)
§ 18    COST OF OVER-SIZE IMPROVEMENTS.
   The subdivider shall be required to pay for only that part of the construction costs for the arterial streets, trunk sewers, or water lines which are serving the proposed subdivision as determined by the Director of Public Safety and Service. The city shall pay the difference between the cost of required improvements for the proposed subdivision and improvements required to service the surrounding areas specified in § 17 above.
(1993 Code Ch. 155 Appx. A.)
§ 19    EXTENSIONS TO BOUNDARIES.
   The subdivider may be required to extend the necessary improvements to the boundary of the proposed subdivision to serve adjoining unsubdivided land as determined by the Commission.
(1993 Code Ch. 155 Appx. A.)
§ 20    OFF-SITE EXTENSIONS.
   If streets or utilities are available at the boundary of a proposed subdivision, and if the Commission finds the extensions across undeveloped areas would not be warranted as a special assessment to the intervening properties or as a municipal expense until some future time. the subdivider may be required, prior to approval of the final plat, to obtain necessary easements or rights-of-way and construct and pay for such extensions. Such improvements shall be available for connections by subdividers of adjoining land.
(1993 Code Ch. 155 Appx. A.)
§ 21    EROSION AND SEDIMENTATION CONTROL.
   Effective erosion and sediment controls shall be planned and applied according to the following principles:
   (A)    The smallest practical area of land should be exposed at anyone time during development.
   (B)    When land is exposed during development, the exposure should be kept to the shortest practical period of time.
   (C)    Temporary vegetation, such as rye grass seeding, or mulching shall be used to protect high erosion potential or other critical areas exposed during development.
   (D)    Sediment basins (debris basins, desilting basins, or silt traps) shall be installed and maintained to remove sediment from run-off waters from land undergoing development.
   (E)    Provisions shall be made to effectively accommodate the increased run-off caused by changed soil and surface conditions during and after development.
   (F)    The permanent final vegetation cover and storm water management structures shall be installed as soon as practical.
   (G)    The development plan shall be fitted to the topography and soils so as to create the least erosion potential.
   (H)    Wherever feasible, natural vegetation should be retained and protected.
      (1993 Code Ch. 155 Appx. A.)
§ 22    FINAL INSPECTION.
   On completion of all the improvements, the subdivider shall request, in writing, a final inspection by the Director of Public Safety and Service as required under Ohio R.C. 711.091.
