This includes the work of producing crops, including tillage, land clearing, plowing, disking, harrowing, planting, harvesting crops or pasturing and raising of livestock, and installation of conservation measures. Construction of new buildings or impervious area is not considered an agricultural activity.
ALTERATION
As applied to land, a change in topography as a result of the moving of soil and rock from one location or position to another; also the changing of surface conditions by causing the surface to be more or less impervious as the result of changing the land cover, including the water, vegetation and bare soil.
APPLICANT
A person who has filed an application for approval to engage in any regulated activity defined in § 17-105 of this chapter.
AS-BUILT DRAWINGS
