The principal purpose of the Mixed Use (MU) District is to encourage the implementation of diverse but compatible land uses, such as a mixture of residential, office, retail, recreational, tourist-related, craft-related and similar uses in a manner in which the uses complement each other. All developments in the Mixed Use (MU) District shall be subject to plan review through the conditional use plan review process. In utilizing the plan review process, the regulations of this district encourage planned locations containing appropriate densities, height and mixture of uses for new residential and commercial uses. The regulations recognize that areas in and near the Borough already cater to tourists who make use of existing antique and flea market facilities. Provisions in this district will complement those existing facilities by providing housing for the proprietors and patrons of those facilities, by providing services for the facilities, proprietors and patrons as well as by providing compatible commercial, trade and craft facilities. Among the services offered may be lodging arrangements commonly referred to as "bed-and-breakfast" facilities or small country inns. Additional purposes of the district are to encourage the preservation of existing natural features, including woodlands and natural waterways, and to serve as a buffer to adjacent residential uses. The regulations in this district also seek to encourage sufficient allocation of land and design of pedestrian and vehicular circulation patterns to meet the objective of providing an efficient, well-planned area.
