(c) Municipal liability. Any determination that a proposed use complies with this district, or any approval of a subdivision or land development plan, or any issuance of a building permit within or near the Steep Slope Conservation District, shall not constitute a representation, guarantee or warranty of any kind by the township, or by any official or employee thereof, of the practicability or safety of the proposed use and shall create no liability upon the township, its officials or employees.

(d) Areas of very steep slope have a vertical slope of greater than or equal to 25%.
(e) All contours must be shown at a two-foot vertical change interval. All areas of steep slope and areas of very steep slope must be depicted clearly using hatching or shading to differentiate between the two areas.
(f) The use regulations of § 1288.05 below are only applicable where contiguous areas of steep or very steep slopes, or of any combination of these two categories, continue over a vertical grade change of ten feet or more.

(a) In addition to the standards described in Chapter 1290 relating to conditional uses, the Township Commissioners shall consider the following aspects of a conditional use application when considering requests for a conditional use under this chapter:
(1) The extent to which the proposal would impact the topography, soils and vegetation and the methods proposed to mitigate potential adverse environmental impacts;
(2) The potential impact of the proposal on adjacent properties; and
(3) The degree to which the proposal is consistent with the objectives in § 1288.01.
(b) Prior to approval of a conditional use application, the applicant shall provide evidence that:
(1) The development or use is being proposed in the Steep Slope Conservation District because no other location is feasible;
(2) Earthmoving activities and vegetation removal will be conducted only to the extent necessary to accommodate proposed uses and structures and in a manner that will not cause excessive surface water runoff, erosion, sedimentation and unstable soil conditions;
(3) Mitigation techniques will be utilized, including, but not limited to, retaining walls, tree wells, the establishment of ground covers and/or low spreading shrubs, the use of erosion control fabric and the like. Such techniques shall be evidenced through the submission of plans and construction details which depict, delineate and otherwise describe the land development proposal; and
(4) Proposed buildings and structures will be of sound geotechnical engineering design, and footings will be designed in response to the site’s slope, soil, and bedrock characteristics.
