Bedrock shall mean the solid undisturbed rock in place either at the ground surface or beneath surface soil deposits.
(3)
Borrow pit shall mean the source of earth or bank-run sand and gravel from below the ground surface by open pit excavation as a single incident on a site for use at a specific construction site elsewhere, or in conjunction with rubble fill.
(4)
Class I fill shall mean load-bearing fills proposed for support of buildings, walls and other structures, the functions thereof which would be substantially impaired by settlement.
(5)
Class II fill shall mean load-bearing fills proposed for support of roadways, pavements, rigid utility lines, house connections and structures which would not be substantially impaired by moderate settlement.
(6)
Class III fill shall mean common fill proposed for landscaping or for other nonload bearing usage.
(7)
Compaction shall mean densification of a soil or rock fill by mechanical or other acceptable procedures.
(8)
Embankment or fill shall mean deposit of soil, rock or other materials placed by man.
(9)
Engineering geology shall mean the application of geological data and principles to engineering problems dealing with naturally occurring rock and soil, for the purpose of assuring that geological factors are recognized and adequately interpreted in engineering practice.
(10)
Erosion shall mean the process by which the ground surface natural or developed, is worn away by the action of wind or water or both.
(11)
Excavation or cut shall mean an act or series of acts by which soil or rock is cut into, dug, quarried, uncovered, removed, disposed or relocated and shall include the conditions resulting therefrom.
(12)
Existing grade shall mean the vertical location of the existing ground surface prior to excavating or filling.

(24)
Slope shall mean the inclined exposed surface of a fill, excavation or natural terrain.
(25)
Soil shall mean all earth material of whatever origin that overlies bedrock and may include the decomposed zone of bedrock which can be readily excavated by mechanical means.
(26)
Soils engineer shall mean a professional engineer who is qualified by education and experience to practice applied soil mechanics and foundation engineering.
(27)
Stripping shall mean any activity which removes or significantly disturbs the vegetable surface cover including clearing, grubbing and top soil removal.
(28)
