1102.01 MODIFIED SECTIONS OF THE OBOA/CABO ONE, TWO AND THREE FAMILY DWELLING CODE.
   The following sections or subsections of the OBOA/CABO One, Two and Three Family Dwelling Code are modified, and enacted as modified, for the Seven Hills Building Code.
   301.7 SURFACE DRAINAGE.
   (a)    Grading or Filling. No person shall commence the construction or erection of any building or dwelling or obtain a permit therefor without first making application in writing to the Commissioner of Buildings on a form furnished by him, to have the Commissioner of Buildings establish the elevation of the first floor joist plate of the proposed building or dwelling, and the grade of the lot or land on which it is constructed. The Commissioner of Buildings shall be notified when the first floor joist plate has been installed to original ground grade as set, and shall perform a recheck of such elevation within forty-eight hours after such notice. No further work shall be commenced on the building or dwelling until such recheck has been completed by the Commissioner of Building. The elevation of the first floor plate shall not be in excess of twenty-eight inches above the highest finished yard grade as set by the Commissioner of Buildings. The Commissioner of Buildings shall set yard grades at the two front house corners, and such grades shall be established by taking into consideration:
      (1)    Grade of the street as existing and/or proposed;
      (2)    Grade and/or contour of the lot or land in question and adjacent property;
      (3)    Setback of the proposed building or dwelling; and
      (4)    Such other factors as the Commissioner of Buildings deems necessary in conformity with good construction and engineering practice.
   (b)    Retaining Walls. The owner or possessor of any lot or land, who fills a lot so that the surface of the same is above the established grade of the street, streets, or alleys upon which such lot or land abuts, and above the existing surface of any adjoining lot or land abuts, and above the existing surface of any adjoining lot or land shall at his own expense, build such retaining walls as may be required to protect properly all adjoining property from damage on account of such fill.
       (1)    If retaining walls are constructed, no parts thereof should exceed two feet in height and the design and installation of the same shall be subject to the approval of the Commissioner of Buildings.
      (2)    In addition to the retaining walls, the owner or possessor of such lot or land shall also construct at his expense and on his lot or land adequate drainage for surface waters consisting of farm drain tile, or the French type of drain covered with slag, if suitable, so as to protect all adjoining property from surface waters on account of such fill.
      (3)    If, however, it is determined by the Commissioner of Buildings, that a drain will provide suitable protection against surface water, same should be of farm drain tile construction or French type drain made of slag, either of which should be laid at the junction of adjoining property and should drain into the nearest outlet.
      (4)    The Commissioner of Buildings must approve every installation for drainage required by this chapter.
   (c)    Positive Drainage. Positive drainage shall be provided for each lot or plot by proper draining so that a nuisance will not be created. Catch basins, yard drains or properly connected under drains shall be installed, or other approved provisions made where water may pocket, to preclude the accumulation of surface water. The Commissioner of Buildings shall determine in all cases the necessity for such catch basins, yard drains or under drains. The plot plan of the sublot involved shall be reviewed by the Commissioner of Buildings at the time an application for a building permit is made, and such Commissioner of Buildings shall cause to be marked thereon the required drainage system for such lot as, in his determination, will probably control the surface waters of such lot. Such drainage system and yard drains shall be constructed and installed at the same time as the foundation of the structure is constructed. Regrading shall be done so that existing natural ground drainage of the surrounding area shall not be impeded. The Commissioner of Buildings may adopt rules or plans for the drainage of lots or plots, which rules or plan shall be followed by the owner, unless permission for deviation is given by the Sewers, Sanitation, Public Health and Water Committees of Council. When a lot or plot is graded to a higher or lower level than the natural grade on an adjacent property, the owner of such lot or plot shall provide suitable slopes or retaining walls or other protection approved by the Commissioner of Buildings on his own property, to preserve the natural slope or surface elevation of such property.
