(a) "Average percent slope."
Average percent slope "S" is computed by the formula:
S = 0.00229 I L
A
where S = Average percent slope
I = Contour interval, in feet*
L = Summation of length of contours, in feet
A = Area in acres of parcel being considered
* Calculations of average percent slope should be based upon accurate topographic surveys using a contour interval no greater than ten feet and a horizontal map scale of 1": 200' or larger. The area of the zoning lot shall be used in this calculation.
(a) "Cut" means a portion of land surface or areas from which the earth has been removed or will be removed by excavation; the depth below the original ground surface or excavating surface.
(b) "Earth moving" means any excavating, cutting or filling, or any stockpiling thereof.
(c) "Erosion" means the general process whereby soils are detached and moved by the flow of surface or subsurface water, wind, ice and gravity.
(d) "Excavating" means removing of soil or other materials by any means whatsoever from water or land on or beneath the surface thereof or beneath the land surface, whether exposed or submerged.
(e) "Fill" means depositing of soil, rock or other materials by other than natural means.
(f) "Finished grade" means the final grade or elevation of the ground surface after grading is completed.
(g) "Geotechnical Engineer" means a Registered Professional Engineer in the State of Ohio with training in geotechnical engineering and experience in slope stability analysis and stabilization methods.
(h) "Grade" means the degree of rise or descent of a sloping surface.
(i) "Grading" means any excavating, cutting or filling, stockpiling of land or earth or combination thereof, including the conditions resulting from any of the above.
(j) "Hillside area" includes land in all zoning districts in the Municipality with an average percent slope of twelve percent (12%) or greater and any area contiguous to such a slope within a distance of one times the height of the slope.
(k) "Hillside control measures" means all of the planning work and control that is required and specified by this chapter.
(l) "Impervious surface" means roads, buildings and structures as defined in Section 1107.05 of the Planning and Zoning Code, tennis courts, roofs, driveways, sidewalks, pools, patios, pool decks, decks, parking lots and other similar surfaces.
(m) "Natural ground surface" means the ground surface in its original state before any grading, excavation or filling.
(n) "Natural vegetation" means plant materials which are indigenous to the area and exist on a site prior to any construction or earth moving activity.
(o) "Owner/developer/builder" means an individual, firm, association, syndicate, limited liability company, limited liability partnership, partnership or corporation having sufficient proprietary interest to seek development of land.
(p) "Run-off" means the part of precipitation which flows over land without filtering into the soil.
(q) "Undisturbed" means that portion of the parcel to be developed which will not be regraded, have any vegetation removed from or have any impervious surface constructed on or over as specified in this chapter.
