§ 150.019 DRAINAGE.
   (A)   An accurate map shall be prepared by the City Engineer clearly showing thereon all natural drainage channels located within the corporate limits of the city, which map shall be displayed in the office of the Building Inspector and available there for public inspection.
   (B)   No building permit shall be issued for any construction on any lot over which a natural drainage channel, as shown on the map, passes, unless and until the plans for the structure shall have been submitted to and approved by the City Engineer, which approval shall be given in writing to the Building Inspector.
   (C)   The City Engineer shall approve all plans submitted hereunder unless the structure built in accordance therewith would result in blocking any natural drainage channel. If the structure built in accordance with this plan would result in blocking a natural drainage channel, and no adequate, suitable or proper alternative means of drainage is provided, the City Engineer shall not approve the plans, in which event he or she shall notify the Building Inspector of the disapproval in writing, giving his or her reasons for the disapproval.
   (D)   Where over 50% of a lot is either covered with a permanent structure or a permanent surface which is impervious to moisture, or both, the owner of the lot shall provide for drainage of surface water to a storm sewer if one is within 500 feet of the lot, or, if there is no storm sewer within 500 feet of the lot, the owner shall dispose of the surface water in a manner approved by the City Engineer. Detached one- and two-family dwellings are exempt from the requirements in this section. This requirement may be waived by majority vote of the City Council where, after receipt of a written request from the affected property owner and review of the recommendation of the City Engineer, the Council determines that strict application of this subchapter causes unreasonable financial burden to the property owner.
   (E)   Where the proposed construction lies within a subdivision which has an approved final drainage plan, all grading on the property shall be completed in accordance with that plan. A drainage plan shall be submitted in accordance with §§ 152.350 through 152.361. No owner, developer or contractor shall initiate building or parking lot construction prior to receipt and approval of the plan by the City Engineer or his or her designate.
   (F)   (1)   All sump pumps installed after January 1, 1992 in any premises, not including replacements, shall be maintained so that the discharge from the sump pump shall be either:
         (a)   Directly into a storm, sewer; or
         (b)   Onto the ground in the back or front yard of the lot at a point which is no closer than ten feet from any lot line.
      (2)   REPLACEMENTS shall be construed to mean the replacement of any existing sump pump with or without modification to the interior piping only. Replacement of any exterior, underground piping for any reason shall require the exterior discharge piping in its entirety to comply with rules in effect for new installations.
