§ 155.144 SUPPLEMENTAL SITE PLAN AND BUILDING PERMIT REQUIREMENTS FOR STEEP SLOPES.
   (A)   In addition to complying with all the requirements listed in § 155.040, the requirements of § 155.131, and § 155.056 the applicant must produce the information provided in divisions (B) through (E) below.
   (B)   A geotechnical engineering report from an engineer licensed in Indiana, Illinois or Michigan to demonstrate:
      (1)   An accurate estimate of the amount of sand or other material in cubic yards expected to be excavated, graded, filled or transported during the life of the permit, and if excavation is to occur, the location of where the excavated material will be finally deposited;
      (2)   The construction, excavation, digging, grading, change of contour, including of trees and vegetation, site restoration and remediation, contemplated in the applicant's site plan will not damage or interfere with the established slope terrain or slope stability; create erosion; cause water drainage problems; change water drainage or obstruct or retard the flow of water; or threaten the safety of neighboring properties; and
      (3)   A slope stability analysis of the dune including a discussion of the effect of construction and excavation as well as the effect of the location of the structure on the dune.
   (C)   The applicant's plans must show:
      (1)   A site diagram, in scale and adequate detail, that indicates the areas of the site with contours of 0 to 10% slope, greater than 10% to 20%, greater than 20% to 33%, and greater than 33%;
      (2)   A complete description of the area affected during construction or excavation activities;
      (3)   All precautions which will be taken during construction to protect the area;
      (4)   All monitoring which will occur, during construction or excavation;
      (5)   All efforts which will be taken to restore the site after construction to the original slope;
      (6)   All studies conducted on the site to support any conclusions; and
      (7)   A three-dimensional drawing or model of the structure on the proposed site.
   (D)   The applicant's plans shall adapt to and minimize disturbance of the natural terrain, trees and other vegetation both during construction and after construction, including plans for implementing the following storm water controls:
      (1)   The location and placement of structural controls to eliminate soil erosion and sedimentation from areas of the site where construction has disturbed the preconstruction land surface; and
      (2)   Temporary stabilization of the disturbed land surface within five business days of completion of construction to re-vegetate with sod, seed, soil blanket, or implement similar measures followed by permanent stabilization before project completion using measures such as landscaping, retaining walls, hard surfaces, and water flow dissipators.
   (E)   The applicant's plans shall contain landscape enhancement and shall provide for the planting of non-invasive trees and native vegetation designed to stabilize the dune and protect it from future movement.
   (F)   The Committee may require a minimum setback for equipment movement or storage.
