Sec. 14-390. - Stormwater management plans.
   Stormwater management plans shall:
   (1)   Include drawings, maps, supporting calculations, specifications, and summaries as outlined in the stormwater design manual.
   (2)   Demonstrate through accepted engineering practices described in the stormwater design manual the impacts of the proposed development. Impacts of the proposed development shall include:
      a.   Effects on existing upstream and/or downstream drainage systems and property;
      b.   Ability of the natural drainageway to handle additional stormwater runoff; and
      c.   Site-specific criteria supporting the analysis of any impacts noted in subsections (2)a. and (2)b. of this section.
   (3)   Demonstrate through accepted engineering practices described in the stormwater design manual that stormwater runoff is adequately conveyed through the development in a drainage system designed to meet the criteria described in the stormwater design manual.
   (4)   Demonstrate through accepted engineering practices described in the stormwater design manual that stormwater facilities required to control the impacts of the development are designed to meet the criteria described in the stormwater design manual.
   (5)   Demonstrate that the nitrogen loading from the new development does not exceed the limits set forth in section 14-387.
