(C) Location of any buildings, structures, designated or otherwise known
<br />historic, burial and archaeological sites, known previous grading and
<br />grubbing sites, large trees, definable rock outcroppings, lava tubes, and
<br />other significant topographic features on the property where the work is to
<br />be performed;
<br />(D) Location of any buildings, structures, designated or otherwise known
<br />historic, burial and archaeological sites on adjacent property which is
<br />within fifteen feet of the area to be graded that may be affected by the
<br />grading work;
<br />(E) Contours, elevations and cross-sections showing the topography of the
<br />land before and after the completion of the proposed grading.
<br />(F) Contours showing the topography of the existing ground extending five
<br />feet into adjacent property when required by the director of public works.
<br />(G) Location of known water courses;
<br />(H) Location of temporary and permanent BMPs;
<br />(I) The area in square feet of the land to be graded and the quantities of
<br />excavation and fill involved; and
<br />(J) Any additional plans, drawings, or calculations required by the director of
<br />public works.
<br />(2) For grading of areas of more than fifteen thousand square feet an erosion control
<br />plan shall be prepared by an engineer and approved by the director of public
<br />works. This plan shall include detailed plans, and specifications of all drainage.
<br />devices and utilities, including bank protection, walls, cribbing, dams, silting or
<br />sediment basins, landscaping, screen planting, erosion control planting, or other
<br />BMPs or protective devices to be constructed in connection with, or as a part of
<br />the proposed work, together with a map showing the drainage area and estimated'
<br />runoff of the area served by any drains.
<br />(3) Where a proposed cut or fill is greater than fifteen feet in height, or on land with
<br />slopes exceeding fifteen percent in an area with high plasticity soils, or when any
<br />fill is to be placed over a swamp, pond, gully, or lake, the permittee shall submit
<br />an engineer's soils report which shall include data regarding the nature,
<br />distribution and strength of existing soils and substantiating data from an engineer
<br />regarding the safety of the proposed grading, the fill, and the material to be used,
<br />and describing the cut sections showing the height, cut slope, benches, and
<br />material composing the cut bank.
<br />(c) An applicant for a grubbing permit shall furnish three sets of plot plans showing
<br />the location, the property boundaries, and any other pertinent information as may
<br />be required by the director of public works. Grubbing or land clearing by
<br />bulldozer for the purpose of making topographic survey shall not be permitted
<br />without an authorized grubbing permit. For grubbing more than one acre, an
<br />erosion control plan shall be prepared by an engineer and approved by the director
<br />of public works. This plan shall include detailed plans, and specifications of all
<br />drainage devices and utilities, including bank protection, walls, cribbing, dams,
<br />silting or sediment basins, landscaping, screen planting, erosion control planting,
<br />or other BMPs or protective devices to be constructed in connection with, or as a
