The content of the erosion and sediment control plan shall meet the criteria as referenced in 327 I.A.C. 15-5, or as provided in this chapter.
(A) Requirements for projects that will disturb 40,000 square feet or more of the site:
(1) A map of the site in adequate detail to show the site and adjacent areas, including the following:
(a) Site boundaries, easements and right-of-ways and adjacent lands which accurately portray the site location;
(b) Lakes, streams, channels, ditches, wetlands and other watercourses on and adjacent to the site;
(c) One hundred-year floodplains, floodway fringes and floodways;
(d) Location of the predominant soil types which may be determined by the United States Department of Agriculture, NRCS County Soil Survey or an equivalent publication, or as determined by a certified professional soil scientist;
(e) Location and delineation of vegetative cover such as grass, weeds, brush and trees;
(f) Location and approximate dimensions of storm water drainage systems and natural drainage patterns on, and immediately adjacent to, the site;
(g) Locations and approximate dimensions of utilities, structures, roads, highways and paving;
(h) Site topography, both existing and planned, at a contour interval appropriate to indicate drainage patterns; and
(i) Potential areas where point source discharges of storm water may enter ground water via surface or subsurface features (i.e., sinkholes and the like), if any.
(2) A plan of final site conditions on the same scale as the existing site map showing the site changes; and
(3) A site construction plan shall include, but is not limited to, the following:
(a) Locations and approximate dimensions of all proposed land disturbing activities;
(b) Potential locations of soil stockpiles;
(c) Locations and approximate dimensions of all erosion control measures necessary to meet the requirements of this rule;
(d) Schedule of the anticipated initiation and completion dates of each land disturbing activity, including the installation of erosion control measures needed to meet the requirements of this rule;
(e) Provisions, including a schedule, for maintenance of the erosion control measures during construction; and
(f) Where feasible, preserve vegetation that exists on the site prior to the initiation of land disturbing activities.
(B) Requirements for projects that will disturb less than 40,000 square feet, and that have a land slope of greater than 2%:
(1) A site plan, drawn to engineer’s scale, including:
(a) The site or building lot, the proposed building location and the location of existing buildings, easements and rights-of-way on the site;
(b) Accurate dimensions of the site, lots and buildings;
(c) Location, size and use of any and all buildings not on the site, but within 50 feet of the site boundaries, unless separated by a street; and
(d) Other information as shall be necessary to comply with the zoning ordinance.
(2) An erosion control plan, including:
(a) Description and location of the specific measures that the applicant proposes to employ to minimize soil erosion and the migration of soil off of the site via surface or underground paths;
(b) Sequence of construction, including each land disturbing activity and the installation of erosion and sediment control measures; and
(c) Provisions for maintenance of the erosion and sediment control measures.
