In the event that co-location is found to be not technically feasible, a written statement of the reasons for the infeasibility shall be submitted to the Borough Clerk and the Planning Board. The Borough may retain a technical expert in the field of RF engineering to certify if co-location at the site is not feasible given the design configuration most accommodating to co-location. The cost for such a technical expert will be at the expense of the applicant. The Borough may deny approval to an applicant that has not demonstrated a good faith effort to provide for co-location.
