A Stormwater management permit for Minor land disturbance needs to be completed when there is an addition of between 1,000-4,999 square feet of new impervious area or a land disturbance between 5,000 square feet and 1 acre. A Stormwater management permit Major land disturbance is required when there is an addition of 5,000 square feet or greater (up to 2/3 of lot) of new impervious area or a land disturbance over 1 acre.
