§ 155.43 DRAINAGE.
   (A)   Travel parks shall make adequate provisions for stormwater or floodwater runoff to prevent erosion, flooding, sedimentation and flooding of ditches or streams, destruction of natural drainage channels and flooding of adjacent properties. Travel parks under construction shall provide erosion control plans for approval by the Public Works Director and the SDDANR. Erosion control plans shall include temporary and permanent erosion control measures and facilities.
   (B)   (1)   General requirements. Drainage facilities shall be installed to prevent erosion, flooding or hazards to the use of the roads, camping sites or facilities within the park and to adjacent and downstream private or public property.
      (2)   Drainage plan. All persons applying for travel park approval shall provide a drainage plan for surface and pertinent subsurface water flows entering, flowing within and leaving the park property. The drainage plan shall provide stormwater calculations, design information and construction details. The drainage plan shall be approved by the Public Works Department and SDDANR.
      (3)   Drainage system. The stormwater drainage system shall be separate and independent of any sanitary sewer system. The drainage system and facilities shall conform to city standards and have approval from the Public Works Department. Natural drainageways shall be utilized wherever feasible, be buffered from roadways and shall not be altered unless the drainage plan shows that alternative drainage facilities are needed and provided.
      (4)   Drainage easements. Where a travel park is traversed by a watercourse, drainage channel or stream necessary for upstream or upland drainage, provisions shall be made for a drainage easement conforming substantially with the alignment of the watercourse and of an adequate width for maintenance and erosion control purposes. This requirement shall not entail any responsibilities for watercourse maintenance on the part of the city, and arrangements for maintenance may be required to the satisfaction of the Public Works Department.
      (5)   Requirements reduced or modified. Drainage plans and system requirements may be reduced or modified if, in the opinion of the Public Works Director, such reduction or modification is necessary or appropriate to carry out the purpose and intent of this section.    
   (C)   Travel parks shall be constructed or placed in such a manner so as to ensure adequate drainage and protect property and improvements in accordance with the city standards. Grading, drainage and erosion control plans shall be prepared in accordance with ordinances of the city.
