An ACOD may be established as an "overlay" district to any conventional underlying zoning districts. Where such overlay district is established, in each matter, whichever provision of the ACOD or the underlying district is most restrictive upon the structure or use shall apply. All of the use, yard, bulk, and other requirements of the underlying zoning district shall apply, except that within an ACOD, any activity regulated by this chapter that is visible from a public street shall also comply with this chapter.
