Conditional uses. Before any permit shall be issued for a conditional use, application shall be made to the Planning Board. The Planning Board shall grant or deny the application after public hearing, but within 95 days of submission on a complete application to the administrative officer, or within such further time as may be consented to by the applicant. Where a conditional use application involves a site plan or subdivision, the Planning Board shall review and approve or deny the subdivision or site plan simultaneously with the conditional use application. Failure of the Planning Board to act within the required time period shall constitute approval of the application. In reviewing the conditional use application, the Planning Board shall review the number of employees or users of the property and the requirements set forth in the ordinance and shall give due consideration to all reasonable elements which would affect the public health, welfare, safety, comfort and convenience, such as but not limited to the proposed use(s), the character of the area, vehicular travel patterns and access, pedestrianways, landscaping, lighting, signs, drainage, sewage treatment, potable water supply, utilities and structural location(s) and orientation(s), and shall conduct a public hearing on the application. The uses for which conditional uses are granted shall be deemed to be permitted uses in their respective districts, and each conditional use shall be considered as an individual case. In all requests for approval of conditional uses, the burden of proof shall be on the applicant. All conditional uses shall require site plan review and approval by the Planning Board. Prior to making its decision, the Planning Board shall be satisfied that the conditional use is reasonably necessary for the convenience of the public in the location proposed.
