A.
For any of the activities regulated by this chapter,
the final approval of subdivision and/or land development plans, the
issuance of any building or occupancy permit, or the commencement
of any land disturbance activity may not proceed until the property
owner or developer or his/her agent has received written approval

A.
Exemptions are as follows:
(1)
Any regulated activity that would create 2,500 square
feet or less of impervious area is exempt from the provisions of this
chapter. This criteria shall apply to the total development (entire
parent tract) even if the development is to take place in phases.
The date of adoption of this chapter shall be the point from which
to consider tracts as parent tracts for which impervious area shall
be inclusively considered. The developer shall be responsible to ensure
that exempted activities shall maintain sound building and construction
practices such that the quantity, velocity and direction of the resulting
