Where land is being developed under the conservation subdivision design requirements of Article XIX, which provides for identification and preservation of sensitive environmental features, the provisions of this article shall complement but shall not be in addition to those requirements.
C.
In the event that two or more natural resource areas identified in this article overlap, the resource with the most-restrictive standard (the least amount of alteration, regrading, clearing, or building) shall apply to the area of overlap.
