(a) After approval of the preliminary plat and prior to the approval of the final plat and/or construction drawings, the developer shall submit to the City Engineer a general grading plan for the entire subdivision or development. The Engineer shall review the plan in accordance with the standards set forth in Chapter 1254 to ensure the control of soil sediment pollution caused by accelerated erosion during development and by accelerated stormwater runoff after development. If, in the judgment of the City Engineer, the topography is such that the drainage of the sublots or parcels shall require the installation of storm drains or storm sewers from rear yards, open space and phased development, such storm drains or storm sewers shall be installed by the developer at the time that the sewer and water improvements are installed in the subdivision or development.
(b) If any lot or parcel collects and discharges surface water other than directly to an on-site stream, river or into a storm sewer system, the Engineer shall require regrading of the land or the installation of such inlet basins, catch basins, drainage inlets and/or stormwater control devices as may be necessary to transfer water to an approved point of discharge.
(c) At the time of application for a building permit for the construction of any structure as per Chapter 1424 of the Building and Housing Code, the owner or builder shall submit plans of sufficient detail and scale to show topographic information and notes and other data detailing how stormwater will be collected and conveyed to the approved point of discharge. The City Engineer shall approve, approve with modifications or disapprove the submitted plan within ten days after the date of submission and the applicant shall be notified in writing of the basis for any such disapproval. The Engineer shall offer assistance to the applicant in the preparation of a plan acceptable to the city.
(d) The drainage system approved by the Engineer for any sublot or lands shall be maintained by the owner thereof. The city shall have the right to enter onto such sublot or lands to maintain any drainage system approved by the Engineer in the event the owner thereof shall fail to correct a problem after notification by the Engineer. Any costs incurred shall be chargeable to the property owner, or made a lien on such premises, in accordance with R.C. § 715.47.
(e) In any of the foregoing circumstances, the construction of open drainage ditches as a substitute for such storm drains or storm sewers shall not be permitted.
