Because of the complexity of factors which affect the use of land, it is not appropriate to definitively determine all of the uses permitted in each zone. Recognizing that certain uses, activities and structures are necessary to serve the needs and convenience of the Borough and region and at the same time, realizing that such uses may be or may become harmful to the public health, safety, and general welfare if located and operated without proper consideration of existing conditions and character of surrounding property, such uses are hereby designated "conditional uses" and listed as such under the appropriate zone district in the Schedule of District Regulations. (The Schedule of District Regulations is included in Appendix C as an attachment to this chapter.) The intent of this section is to establish a procedure for the Land Use Board to consider these specified uses on a case by case basis. Decisions of the Board on conditional uses shall be rendered after public hearing and shall be based on the standards specified in this section and § 25-18.
