BEST MANAGEMENT PRACTICES (BMPs):
Physical facilities, schedules of activities, prohibitions of practices, maintenance procedures, and other management practices which, when property designed, installed and maintained, will be effective to prevent or reduce the discharge of water or air pollution associated with land disturbance activities.
CLEARCUTTING
Cutting essentially all trees in a given area.
CLEARING:
Any activity by which vegetative cover, structures or surface material are removed, including, but not limited to, surface layer, root or topsoil removal.
DRAINAGE WAY
Any channel that conveys surface runoff within, through and/or away from the site.
EROSION
The wearing away of land by the action of wind, water, gravity, ice, or artificial means, and/or land disturbance activities.
EROSION CONTROL
Measures that prevent erosion.
GRADING
Excavation or fill material, including the resulting conditions thereof.
LAND DISTURBANCE
Any activity that changes the physical conditions of landform, vegetation and hydrology, creates bare soil, or otherwise may cause erosion or sedimentation. Such activities, include, but are not limited to: clearing, removal of vegetation, stripping, grading, grubbing, excavating, filling, logging and storing of materials.
LAND DISTURBANCE PERMIT
A permit issued by Platte County for the construction or alteration of ground improvements and structures for the control of erosion, runoff and grading.
PERENNIAL VEGETATION
Grass or other appropriate natural growing vegetation that provides substantial land cover, erosion protection and soil stability and that is capable of sustained and healthy growth over multiple years under the constraints of shade, temperature, and moisture that will be prevalent on the site.
PERIMETER CONTROL
A barrier that prevent sediment from leaving a site either by filtering sediment-laden runoff or diverting it to a sediment trap or basin.
PHASING
Clearing a parcel of land in distinct phases, with the stabilization of each phase before the clearing of the next.
SEDIMENT
Soils or other materials transported or deposited by the action of wind, water, gravity, ice, or artificial means.
SEDIMENT AND EROSION CONTROL PLAN
A plan for the control of sedimentation and erosion resulting from land disturbance activities, and may include, without being limited to, the drawings, specifications, construction documents, schedules, or other related documents upon with the best management practices to be used on a site are set forth, including such information as necessary to review the basis for their design and to ensure their proper installation, maintenance, inspection, and removal.
SEDIMENT CONTROL
Measures that prevent eroded sediment from leaving the site.
SITE
A parcel of land, or a contiguous combination thereof, where land disturbance work is performed as a single unified operation.
STABILIZATION
The use of practices that prevent exposed soil from eroding.
TREE
Vegetative growth with a trunk six (6) inches in diameter and larger, measured three (3) feet above ground.
VEGETATIVE COVER
Any grasses, shrubs, trees and other vegetation that protects and stabilizes soils.
WATERCOURSE:
Any body of water, including, but not limited to, lakes, ponds, rivers, streams, and bodies of water which are delineated by Platte County.
WATERWAY
A channel that directs surface runoff to a watercourse, or to the public storm drain.
