“Site specific development plan” means a plan which has obtained final development approval from the Town through the land use approval process, including notice and public hearing, and which describes with reasonable certainty the type and intensity of use for a specific parcel or parcels of property and includes all of the terms and conditions of such approval. Site specific development plans may include, or be in the form of, a planned unit development (PUD) plan, a subdivision plat, a subdivision improvements agreement, a use or activity permitted on review, a development agreement, a certificate of appropriateness, or such other document as identified and agreed upon by the Town and a landowner or developer. A license, map, variance, easement or permit shall not constitute a site specific development plan.
