A long-range planning document that describes separate construction projects, such as a 20-year transportation improvement plan, is not a common plan of development.
NR 216.002(3)
(3) “Contaminated storm water" means storm water that comes into contact with material handling equipment or activities, raw materials, intermediate products, final products, waste materials, byproducts or industrial machinery in the source areas listed in s.

(7) “Erosion" means the process by which the land's surface is worn away by the action of wind, water, ice or gravity.
NR 216.002(8)
(8) “Final stabilization" means that all land disturbing construction activities at the construction site have been completed and that a uniform perennial vegetative cover has been established with a density of at least 70% of the cover for the unpaved areas and areas not covered by permanent structures or that employ equivalent permanent stabilization measures.
NR 216.002(9)
(9) “General WPDES permit" or “general permit" means a permit for the discharge of pollutants issued by the department under s.

NR 216.002(14)
(14) “Land disturbing construction activity" means any man-made alteration of the land surface resulting in a change in the topography or existing vegetative or non-vegetative soil cover that may result in storm water runoff and lead to increased soil erosion and movement of sediment into waters of the state.
