An applicant shall submit an erosion and sediment control plan that complies with the requirements of the Soil Conservation District, this title, the Standards and Specifications, and the Stormwater Management Act of 2007.
(2)
The plans shall include sufficient information to evaluate the environmental characteristics of the affected areas, the potential impacts of the proposed grading on water resources, and the effectiveness and acceptability of measures proposed to minimize soil erosion and off-site sedimentation.
(b)
Other documents to be submitted. An applicant shall submit the following information:
(1)
A letter of transmittal or application, or both;

The name, address, and telephone number of:
(i)
The owner of the property where the grading is proposed;
(ii)
The developer; and
(iii)
The applicant;
(3)
A vicinity map indicating north arrow, scale, site location, and other information necessary to easily locate the property;
(4)
Drainage area map(s) at a 1" = 200' minimum scale showing existing, interim, and proposed topography, proposed improvements, standard symbols for proposed sediment control features, and pertinent drainage information including provisions to protect downstream areas from erosion for a minimum of 200 feet downstream or to the next conveyance system;
(5)
The location of natural resources, wetlands, floodplains, highly erodible soils, slopes 15 percent and steeper, and any other sensitive areas;
(6)
A general description of the predominant soil types on the site, as described by the appropriate soil survey information available through the District or the USDA Natural Resources Soil Conservation Service;
(7)
Proposed stormwater management practices;
(8)
Erosion and sediment control plans including:
(i)
The existing topography and improvements as well as proposed topography and improvements at a scale between 1" = 10' and 1" = 50' with 2 foot contours or other approved contour interval (for projects with more than minor grading, interim contours may also be required);
(ii)
Scale, project, and sheet title, and north arrow on each plan sheet;
(iii)
The limit of disturbance (LOD) including:
1.
Limit of grading (grading units, if applicable); and
2.
Initial, interim, and final phases;
(iv)
The proposed grading and earth disturbance including:
1.
Total disturbed area;
2.
Volume of cut and fill quantities; and
3.
Volume of borrow and spoil quantities;
(v)
Storm drainage features, including:
1.
Existing and proposed bridges, storm drains, culverts, outfalls, etc.;
2.
Velocities and peak flow rates at outfalls for the two-year and ten-year frequency storm events; and
3.
Site conditions around points of all surface water discharge from the site;
(vi)
Subject to subsections (c) though (g) of this section, erosion and sediment control practices to minimize on-site erosion and prevent off-site sedimentation including:
1.
The salvage and reuse of topsoil;
2.
Phased construction and implementation of grading unit(s) to minimize disturbances, both in extent and duration;
3.
Location and type of all proposed sediment control practices;
4.
Design details and data for all erosion and sediment control practices; and
5.
Specifications for temporary and permanent stabilization measures including, at a minimum "standard stabilization note" on the plan stating: "Following initial soil disturbance or re-disturbance, permanent or temporary stabilization must be completed within:
A.
Three (3) calendar days as to the surface of all perimeter dikes, swales, ditches, perimeter slopes, and all slopes steeper than 3 horizontal to 1 vertical (3:1); and
B.
Seven (7) calendar days as to all other disturbed or graded areas on the project site not under active grading.;"
6.
Details for areas requiring accelerated stabilization; and
7.
Maintenance requirements as defined in the standards and specifications.
(c)
Sequence of construction.
(1)
Subject to paragraph (3) of this subsection, an applicant shall submit a sequence of construction describing the relationship between the implementation and maintenance of controls, including permanent and temporary stabilization, and the various stages or phases of earth disturbance and construction.
(2)
Any changes or revisions to the sequence of construction shall be approved by the District before proceeding with construction.
(3)
The sequence of construction, at a minimum, shall include the following:
(i)
A request for a pre-construction meeting with the Department of Permits, Approvals and Inspections;
(ii)
Clearing and grubbing as necessary for the installation of perimeter controls;
(iii)
Construction and stabilization of perimeter controls;
(iv)
Remaining clearing and grubbing within installed perimeter controls;
(v)
Road grading;
(vi)
Grading for the remainder of the site;
(vii)
Utility installation and connections to existing structures;
(viii)
Construction of buildings, roads, and other construction;
(ix)
Final grading, landscaping, and stabilization;
(x)
Installation of stormwater management measures;
(xi)
Approval of the Department of Permits, Approvals, and Inspections before removal of sediment controls; and
(xii)
Removal of controls and stabilization of areas that are disturbed by removal of sediment controls.
(d)
Statement of required contacts . An applicant shall submit a statement requiring the owner/developer or representative to contact the Department of Permits, Approvals and Inspections or its agent at the following stages of the project or in accordance with the approved erosion and sediment control plan, grading permit, or building permit:
(1)
Before the start of earth disturbance;
(2)
On completion of the installation of perimeter erosion and sediment controls, but before proceeding with any other earth disturbance or grading;
(3)
Before the start of another phase of construction or opening of another grading unit; and
(4)
Before the removal of sediment control practices.
(e)
Certification by owner/developer.
(1)
An applicant shall submit certification by the owner/developer that any clearing, grading, construction, or development will be done in accordance with the approved erosion and sediment control plan.
(2)
(i)
The certification shall also require that the responsible personnel involved in the construction project have a certificate of training at an administration-approved training program for the control of erosion and sediment before beginning the project.
(ii)
