For any of the activities regulated by this article, the final approval of subdivision and/or land development plans, the issuance of any building or occupancy permit, or the commencement of any earth disturbance activity may not proceed until the property owner or developer or his/her agent has received written approval of a drainage plan from the municipality.
A. 
Any regulated activity described in § 124-70 of this article that is less than or equal to 5,000 square feet of impervious area is exempt from the drainage plan preparation provisions of this article. These criteria shall apply to the total development even if development is to take place in phases. The date of the municipal ordinance adoption by the county shall be the starting point from which to consider tracts as parent tracts in which future subdivisions and respective impervious area computations shall be cumulatively considered. Exemption shall not relieve the applicant from providing adequate stormwater management to meet the purpose of this article.

C. 
Use of land for gardening for home consumption.
