(a) Performance by Engineer Required. All work under this section shall be performed by a registered professional engineer.
(b) Grading. Levels, based on an approved Regional Geodetic Survey datum and bench mark, shall be taken at intervals of fifty feet and at such intermediate points where there is a sharp break in grade, along the centerline of the street, on each side of the street and along each front building line. This information shall be platted to a scale of one inch equals fifty feet horizontally and one inch equals five feet vertically. The engineer shall fix a grade which, when approved by the City Engineer, shall be calculated for each fifty-foot station, with vertical curves at each change in grade.
If, in the opinion of the City Engineer, the topography is of such a nature that the grade location of houses is advisable and if the grading of the lot may adversely affect the owners of adjacent property, the owner of the land proposed to be platted shall have prepared and submitted to the City Engineer a topographical survey made by taking levels on cross-section grid at fifty-foot intervals, showing all buildings, fences, trees or wooded areas and pole lines, etc., platted to a scale of one inch equals fifty feet and contoured to show existing conditions, and the proposed revision shall be adjusted to the grade of houses and regrading of yards.
(c) Storm and Sanitary Sewers; Culverts; Water Mains; House Connections. Wherever outlets for sewers and water mains are available to an allotment, the owner must install and connect, at his or her own cost, all storm and sanitary sewers, culverts, water mains and connections for each sublot from the sewers and water mains to three feet back of the edge of the proposed pavement, which should be not less than twenty-four feet wide, unless a wider width is recommended by Council.
Plans shall be prepared by the owner's engineer, on tracing cloth and in India ink, showing the profile and established grade, as outlined above, and with the water main shown in the plan and storm and sanitary sewers shown in both the plan and profile, all on one plan, to a scale of one inch equals fifty feet horizontally and one inch equals five feet vertically. The location of each house connection, both sewer and water, shall be shown on the plan. The bench mark used shall be shown on the plan.
If, however, water mains and sewer outlet facilities are not available to the property, the plat will not be approved unless some other water supply means and sewage outlet means, meeting with the approval of Council and the public health authorities, are provided for each lot of the subdivision. The title shall show the name of the owner and the name of the street, shall designate that it is in the City and shall be signed and sealed by the owner's engineer. The owner shall furnish complete specifications, in triplicate, meeting the approval of Council, the City Engineer, the County Sanitary Engineering Department and the City of Cleveland, Department of Public Utilities, Division of Water, as may be required, for use by the City Engineer, the Director of Public Service and the Director of Buildings. The plans shall meet the approval of all three agencies and Council.
The duplicate tracing shall be filed with the City Engineer.
(d) Temporary Roadway or Pavement. After underground improvements have been completely installed, a temporary pavement shall be installed consisting of six inches of compacted waterbound macadam, installed upon a graded, compacted subgrade graded to the cross-section of the permanent pavement so that when the permanent pavement is constructed on top of this temporary roadway it will conform to the camber and to the established grade.
A fund, in an amount fixed by the City Engineer, shall be deposited with the City to guarantee the maintenance of a temporary roadway until, in the opinion of the City Engineer, the permanent pavement can be safely installed. To meet the grade of the temporary roadway, all castings shall be adjusted to meet the surface grade of the roadway.
(e) Permanent Pavement. The permanent pavement shall be of seven-inch reinforced concrete with integral curbs of concrete, with the cross-section, width of pavement and specifications and details of construction meeting the approval of the City Engineer and Council, and shall be filed in triplicate with the City Engineer.
(f) Sidewalks and Driveway Aprons. After a house has been built upon a sublot, the owner shall construct sidewalks of concrete to a width of five feet and a depth of four inches, except at driveways, where the depth shall be six inches, built to conform to a slope of three-eighths of an inch per foot rise from the top of the curb, and with the property side of the walk one foot into the street. Concrete driveway aprons shall be built between the curb and walk and shall be a minimum of ten feet wide and six inches thick. Complete specifications, meeting the approval of the City Engineer and Council, shall be filed in duplicate with the City Engineer.
(g) Permanent Monuments. As the pavement is constructed, permanent monuments of either suitable hard stone twenty inches in depth and five inches square, or an iron pin set in a concrete cylinder six inches in diameter and twenty inches in depth, with tops set ten inches below the established grade of the pavement and covered by a cast-iron monument box with a removable cover, shall be set at all points of curve, tangency and intersection.
(h) Underground Telephone, Electric Power and Street Lighting. In all subdivisions of more than ten sublots the following procedure shall be followed and these requirements met:
(1) The preliminary plat with respect to any new subdivision shall be submitted to all utility companies serving the subdivision, as well as to the Director of Buildings and the City Engineer, for their recommendations.
(2) Utility easements at least five feet in width for telephone, electric power and street lighting distribution lines and facilities shall be provided on all front lot lines and along certain side or rear lot lines where necessary.
(3) Prior to granting final approval, the subdivider shall have installed the following items, or shall have furnished adequate bond for their ultimate installation, in accordance with the requirements of the Electrical Code of the City:
A. Underground telephone cables;
B. Underground distribution cables for power and street lighting from a common distribution system, with the equipment and housing necessary for the operation of the distribution system to be underground; and
C. Adequate provision for street lighting lamps and standards in accordance with a design approved by Council.
