§ 102-124 Slope regulations in business districts.
| |||||||
Uses permitted in the business districts generally require a significant portion of the property, in a contiguous area, to be relatively flat in order to site the building and provide reasonable access to and from parking and loading areas. | |||||||
A. It is therefore the goal of these regulations to preferably avoid but at all times carefully control construction in areas of steep slopes (see definition) and abutting sloped areas in order to avoid creating new steep slope areas. The purpose is to minimize the disturbance of established vegetation on existing steep slopes and to avoid creating new steep slopes where the potential for soil erosion is increased due to the slope and the exposed soil needing to be stabilized.
| |||||||
B. For purposes of these provisions, "construction" shall mean any disturbance to land, including but not limited to the site work related to the placement of buildings, structures, streets, driveways, parking areas and similar improvements that involve excavations, fill, grading and clearing, except that selective thinning of vegetation and site work approved by the approving authority for sidewalks and similar pedestrianways, subsurface utility installations and drainage facilities shall not be considered construction.
| |||||||
C. Steep slopes, as defined herein, shall not be disturbed, except where the applicant demonstrates that each disturbance is essential to the reasonable use of the property. The applicant shall submit a separate sheet as part of the overall development plan, identifying the extent of the disturbance on steep slopes and noting the justification(s) for the disturbance.
| |||||||
D. Where construction will disturb steep sloped areas and areas abutting steep slopes, the plan shall provide the following design features, as applicable to the situation:
| |||||||
(1) An area with slopes 10% or more may be completely removed (such as a knob in the middle of the site), provided that the final grading eliminates slopes of 10% or more in the disturbed area and the removed soil is redistributed on site and/or removed from the site in accordance with other Township requirements;
| |||||||
(2) The area along the top of a slope of 10% or more but not more than 15% may be filled and a retaining wall constructed, provided that the horizontal width of the filled area shall not exceed 20 feet and the retaining wall shall be no higher than two feet;
| |||||||
(3) Any area of disturbance on a slope greater than 10% shall not result in a final grade greater than 15%; and
| |||||||
(4) Any grading or disturbance in an area having slopes of 10% or more shall stabilize the soil as required herein in order to avoid soil erosion.
