At the request of the developer, the Planning Board may grant an informal review of a concept plan for a development for which the developer intends to prepare and submit an application for development. A timeframe of 15 minutes shall be allocated for this review. A fee may be required if a professional review is required. If a professional review is required by the Board or if the property lies within a Redevelopment Area, the applicant shall notice all property owners within 200 feet of the lots in question. The concept plan is designed to enable the Planning Board and the applicant to discuss and evaluate principles and potential problems involved before the applicant has gone to the expense of completing detailed engineering drawings as required for further processing of the development application. The opinions offered are not binding on the developer or on the Planning Board.
