    • This is the erosion/stormwater permit for land-disturbing activity; it is not confirmed as the building permit issued for a dwelling.
    • Land disturbance above 5,000 square feet also needs this permit.

    land disturbed threshold for permit: > 5000 square feet (any new building construction needs a permit regardless of size)

    “no person shall engage in any land disturbing activity resulting in a disturbed area of more than five thousand (5,000) square feet or undertake any new building construction regardless of the size of the disturbed area without first obtaining a permit as provided in this article.”
