§ 98.10  ROOF DRAINS AND SUBSURFACE DRAINS.
   (A)   Roof drains. No person or entity owning, constructing or occupying any building shall cause pipes or drains conducting water from the roof of the building to be so constructed as to discharge water from gutters, pipes or other structures within ten feet of any public sidewalk, causing runoff to be concentrated over that public sidewalk.
   (B)   Subsurface drains. No person or entity shall discharge any water or other fluids originating from sumps, sump pits, sump pumps or other pumps, or any reservoir serving as a water drain or receptacle for water, from pipes or other structures to an area within ten feet of the property line or beyond or within ten feet of any public sidewalk, street, street curb or street gutter, unless conveyed by a naturally occurring swale or a drainage swale approved by the Engineering Department or unless the method of drainage is otherwise approved by the Engineering Department taking into consideration the elevation, slope and topography of the premises and adjoining premises.
   (C)   Piping underground. The water as described in divisions (A) and (B) above shall not be piped underground into available underground public storm water conveyances, unless prior written approval from the city is obtained. The property owner shall bear all costs and shall accept all risks for such underground connection to the public storm water conveyance. Approval from the city shall be contingent upon the property owner indemnifying the city for any cost or risk associated with such connection.
   (D)   Discharging prohibitions. No person shall discharge any water or other fluids originated from sumps, sump pits, other pumps or other mechanical means, any reservoir serving as a water drain or receptacle for water, from pipes or other structures, swimming pools or their drains or from roof gutter drains into or onto any adjoining property in such a manner as to create a nuisance as described below:
      (1)   Ponding or stagnating of water;
      (2)   Causing soil erosion;
      (3)   Creating conditions that would deny adjoining property owners reasonable use of their property; or
      (4)   Accumulation of water that freezes, creates mildew/mold or produces offensive odors.
