1167.07  REQUIRED PAVING AND UNDERGROUND IMPROVEMENTS.
   The following paving and underground improvements are required:
   (a)    Streets Generally. Streets shall be cleared, excavated and graded as provided for in the specifications attached hereto, made a part hereof and entitled "Street Excavations", and shall be designed as set forth in Section 1167.09.
   (b)    Public Water Supply; Sanitary and Storm Sewers. Each sublot, parcel and reserve strip in a subdivision shall be provided with a connection to a public water supply, sanitary sewer and storm sewer, each constructed in accordance with the specifications attached hereto, made a part hereof and entitled "Sewers" and "Water".
Installation of such improvements shall be approved by the Cleveland Water Department, Cuyahoga County Sanitary Engineer, Cuyahoga County Board of Health and the City Engineer.
      (1)    If a public water supply is not reasonably accessible to any sublot in a subdivision, then such sublot shall be provided with a well or other private water supply system to supply adequate potable water as approved by the Cuyahoga County Board of Health.
      (2)    If a sanitary sewer connection is not reasonably accessible to any sublot in a subdivision, then such sublot shall be provided with a septic tank properly designed to drain into a storm sewer, all in accordance with the County Board of Health specifications; provided, however, that no septic tanks shall be substituted for sanitary sewers if either a gravity or forced sanitary sewer system can be used in accordance with the City specifications attached hereto, made a part hereof and entitled "Sanitary Sewers". (Ord. 21-1965. Passed 7-13-65.)
      (3)    If a storm sewer connection is not reasonably accessible to a sublot, then such sublot shall be provided with storm drainage facilities as required by the City Engineer in accordance with accepted civil engineering standards and practice. All watercourses and drainage facilities in residential subdivisions shall be enclosed.
         (Ord. 28-1985. Passed 6-18-85.)
   (c)    Culverts and Bridges. Culverts and bridges shall be constructed wherever the topography of the land so requires in accordance with plans and specifications approved by the City Engineer, and made in accordance with accepted civil engineering standards and practices.
   (d)    Street Lighting System. An adequate street lighting system shall be provided by the allotter for the subdivision. Such street lighting system shall have electroliers and continuous underground circuits, except when lights on poles are specifically approved by the Commission. Such street lighting system shall be based on the American Standard Practice for Street and Highway Lighting, as amended, sponsored by the Illuminating Engineering Society and approved by the American Standards Association, Inc., and as approved by the City Engineer.
The allotter shall comply with the requirements of the foregoing paragraph by either providing the aforesaid street lighting system, or agreeing to assessment proceedings for such purpose.
   (e)    Street Rights of Way Provisions.
      (1)    Where the street right of way is less than sixty feet, underground improvements shall be installed as follows:
         A.    Water main, eight feet from center line of street;
         B.    Dual sewer system, on center line of street;
         C.    Single sewer system, one sewer on center line, the other sewer eight feet from center line opposite water main.
      (2)    Where the street right of way is sixty feet or more, underground improvements shall be installed in the tree lawns with the water main in one tree lawn and the sewer in the opposite tree lawn.
      (3)    When the paving is to be installed in the same construction season as the underground improvements, the backfilling of the trenches of the underground improvements shall be in accordance with either subsections (f)(2) or (f)(3) below.
      (4)    When the paving is not to be installed in the same construction season as the underground improvements, the backfill of the trenches shall settle over the following winter. (Ord. 21-1965. Passed 7-13-65.)
      (5)    After the backfill in the trenches has been compacted to the satisfaction of the City Engineer, the streets shall be drained, paved and curbed with reinforced concrete in accordance with City specifications and cross-section plans attached hereto, made a part hereof and entitled "Construction and Material Specifications".
         (Ord. 7-1985. Passed 1-22-85.)
   (f)    Backfilling.
      (1)    All ordinary backfilling of storm and sanitary sewers, water mains, curb connections and appurtenances shall be performed in accordance with the requirements for ordinary backfill as set forth in the standard "Specifications for Sewers and Water" as made a part of the City specifications.
      (2)    All sewer and water construction under the proposed pavement areas and for an additional five feet outside of and adjacent to the proposed pavement areas, as shown on the plans, shall be backfilled with compacted earth, clay or granular soil excavated from the trench. If, in the opinion of the City Engineer, the material excavated from the trench is unsuitable for backfill, the contractor shall, at his own expense, secure suitable material from other locations on the site. The backfill shall be brought up evenly on both sides of the pipe and shall be placed in layers not to exceed four inches in thickness and compacted with mechanical tampers or other approved mechanical compactors, as directed by the City Engineer. The compaction requirement for tamped earth backfill shall be ninety-five percent (95%) of the maximum laboratory dry weight. No backfill shall be done during freezing weather except by permission of the City Engineer, and no backfill shall be made when the material already in the trench is frozen, nor shall frozen material be used in backfilling. The Engineer shall advise Council prior to granting such permission.
      (3)    All sewer and water connections under the proposed pavement areas and for an additional five feet outside of and adjacent to the proposed pavement areas as shown on the plans shall be backfilled with compacted bank sand containing not more than ten percent (10%) by weight of loam or clay and free of all deleterious or objectionable material. All material excavated from the trench shall be removed from the street areas and deposited upon land abutting the improvement in a manner satisfactory to the Engineer. The granular backfill shall be brought up evenly on both sides of the pipe and shall be placed in layers not to exceed six inches in thickness and compacted with mechanical tampers or other approved mechanical compactors, as directed by the City Engineer. Sand backfill may be compacted with water if satisfactory drainage is provided for the free water. When compacted with water, the granular material shall be placed in layers not to exceed twelve inches loose depth and each layer thoroughly saturated with water. No backfill shall be made during freezing weather when the backfill material already in the trench is frozen, nor shall frozen sand be used in backfilling.
   (g)    Monuments. When streets are paved, monuments shall be placed at all intersections, angle points, points of curvature and tangency in streets, and at such intermediate points as shall be required by the City Engineer.
