Questions (Frequently Tested)

Land Disturbing Activity (LDA) - Answer: Any man-made change to the land surface that may result in
soil erosion from water or wind and the movement of sediments into state waters or onto lands in the
Commonwealth.
Regulated LDAs - Answer: · LDAs equal to or greater than 10,000 square feet are subject to the laws and
regulations of the erosion program.
· In all areas of the jurisdictions designated as subject to the Chesapeake Bay Preservation Area (CBPA)
Designation and Management Regulations (i.e., James City County), the regulated land disturbance
threshold drops to 2,500 square feet.
Development - Answer: A tract or parcel of land developed, or to be developed, as a single unit under
single ownership or unified control that is to be used for any business or industrial purpose or is to
contain three or more residential dwelling units.
Erosion Impact Area - Answer: · An area of land NOT associated with current LDA but subject to
persistent soil erosion resulting in the delivery of sediment onto neighboring properties or into state
waters.
· Does not apply to any lot or parcel of land of 10,000 square feet or less used for residential purposes or
to shorelines where the erosion results from wave action or other coastal processes.
Erosion and Sediment Control (ESC or E&SC) Plan - Answer: · Describes the potential for erosion and
sedimentation during a LDA
· Describes the structural and non-structural practices for minimizing erosion and containing sediment
during construction.
· Must review an adequate ESC plan and grant written approval within 60 days.
· If no action is taken within allotted time, plan is deemed approved
