Zoning and permits
Zoning
Permits
C
General Commercial District
The purpose of this article is to provide for, enhance the opportunities for, and protect existing establishments offering a variety of supplies or service which are essential to the economy of Lafayette but which are frequently incompatible with the operations of a retail shopping area because of their need for a large site, access by delivery and customer vehicles, open display or storage yards, and their propensity to produce limited but tolerable external impacts. Such uses ordinarily do not seek locations in shopping areas and therefore must be provided for at independent locations along a major thoroughfare, away from the retail core area.; The number of uses allowed in the C district has been limited in favor of the existing uses and to provide a favorable climate for administrative and consultative activities.; This article is to provide for the implementation of the general plan, which encourages the separation of uses permitted in the retail core area and those permitted elsewhere in the business districts.
Permitted uses
