(A)   Each applicant shall submit the following information to ensure that the provisions of this chapter are met. The submittal shall include sufficient information to evaluate the environmental characteristics of the property, the potential adverse impacts of the development on water resources both on-site and downstream, and the effectiveness of the proposed stormwater management plan in managing stormwater runoff. The applicant shall certify on the drawings that all clearing, grading, drainage and construction shall be accomplished in strict conformance with this chapter.
   (B)   Applicant shall provide a stormwater management plan, prepared by and bearing the stamp and seal of a registered professional engineer, which includes the following information for both existing and proposed property conditions:
      (1)   Narrative description of proposed development and impact on surrounding drainage systems;
      (2)   A location map and description providing township, range and section; showing the properties’ location within the larger watershed; and showing the jurisdictional boundaries of all municipalities, drainage districts and townships within two miles of the project;
      (3)   Existing and proposed topography at a minimum of two-foot contour intervals;
      (4)   Existing and proposed stormwater management features, including (but not limited to) drain tiles, ditches, culverts, swale, storm sewers and structures, detention areas, wetlands, lakes, ponds, streams and the like;
      (5)   Plan, profile and cross sections of stormwater storage facilities, and overland flow routes, including the areas expected to be inundated or covered with water;

      (11)   Sub-watershed boundaries within the property;
      (12)   Delineation of upstream and downstream drainage features that might be affected by the development;
      (13)   Environmental features of the property and immediate vicinity, including wetland areas, natural areas, and proposed environmental mitigation features;
      (14)   Copies of permit applications, permits and signoffs as required by other jurisdictions;
      (15)   Basis of design for all stormwater management system components;
      (16)   Any other information deemed necessary by the Administrator;
