§ 1222.08  STORM WATER AND DRAINAGE.
   (a)   Every subdivision shall be provided with a storm water sewer or drainage system which is adequate to serve the platted area and which otherwise meets standards and specifications of the City.
   (b)   All subdivisions shall be subject to the storm water requirements established in the Manual of Design for Public Improvements and adhere to the Erosion and Sediment Control Regulations.
   (c)   Where feasible, and where a storm sewer of 48 inches or larger would otherwise be required, storm water drainage may be provided by means of ditches in drainage courses, either of grass or paved concrete, approved by the City Engineer, provided that such type of drainage is not located within a street right-of-way. An easement shall be required for such storm sewer.
   (d)   The determination of the necessity for storage basins will be based upon, but not limited to, existing storage basins and existing storm sewer and open channel capacities. Where deemed necessary by the City, the developer shall provide storm water storage basins in accordance with the Manual of Design for Public Improvements.
   (e)   Where detention or retention is required, the basins shall be:
      (1)   Constructed on-site; and
      (2)   Privately maintained by an individual, up to four lot owners, a private company, an association or some other private organization. A maintenance plan shall be included in the subdivision protective covenants and recorded with the subdivision plat.
   (f)   The subdivider may request that the City accept a regional detention/retention basin for perpetual ownership and maintenance by the City, predicated upon guidelines as stated in the Manual of Design for Public Improvements. Conditions of such acceptance include, but are not limited to, the subdivider paying for all costs associated with:
      (1)   The design and construction of all items associated with the basin, including inlet/outlet structures, sewers and other appurtenances; and
      (2)   The transfer of required deeds for land ownership and access easements to the City.
