Should a utility service provider propose, for any reason, whether or not required by law, permit, or order, that any design, redesign, construction, repair, replacement, improvement, modification, upgrade, rehabilitation, alteration, expansion, or addition to any existing or new facility, installation, structure, building, or property installation ("utility development") be located within any zone district, the utility service provider shall provide evidence, in the form and substance as herein required, or as requested by the land use reviewing board, demonstrating that the proposed utility development cannot be located in the Industrial Zone District of the Borough of Hillsdale, or elsewhere.
(2) 
Should a utility service provider propose a utility development, said service provider must obtain site plan approval from the municipal land use board, pursuant to the requirements of Article XXIII of this chapter and all requirements contained in this § 310-67B, prior to commencing any site work on the utility development. Such utility development includes, but is not limited to, changes to electrical substations and their transmission and distribution of power networks; changes to the storage facilities or operations, including enclosed storage units or buildings, containment tanks or vessels, reservoirs and spillways; and the release, transmission, or distribution or transportation over land, by waterways, or through subsurface means of electricity, water, petroleum products, natural or manufactured gases, waste transfer, or any other utility services or utility products within the Borough of Hillsdale.
(3) 
The proposed utility development shall not alter or modify the use or availability of the existing Borough, county or state roadway systems located within the Borough of Hillsdale unless specifically permitted in detail by the land use reviewing board.
(4) 
The proposed utility development shall not alter or modify any properties and the improvements thereon owned or controlled by the Borough of Hillsdale, Bergen County or State of New Jersey. Such properties include, but are not limited to, roadways, municipal buildings, municipal parking areas, Board of Education buildings, recreational facilities, and open space.
(5) 
The utility service provider shall submit to the municipal land use board, in the form and substance requested, an environmental impact study (EIS) demonstrating the utility development and shall be in full compliance with the stormwater management ordinances of the Borough of Hillsdale. The proposed utility development shall not cause, contribute to, or exacerbate the flooding of or detriment to a public or private roadway, public or private watercourse, or municipal or private property. Proof of meeting this requirement shall be included in the EIS submitted to the land use board.
(6) 
The submitted EIS shall include information showing that the proposed utility development shall not impair or divert the movement of wildlife across open spaces either on or below the ground surface, or in the air, in such a way that would be detrimental to the Borough environment. In the alternative, the EIS shall show, or the applicant shall provide through testimony, that such relocation or natural movement of wildlife will not occur or shall be mitigated within the utility property through proven methods. The utility provider shall employ a third-party, New Jersey Department of Environmental Protection, state-recognized, environmental advocate or advocacy organization to approve such mitigation methods or to confirm that no wildlife mitigation is required.
(7) 
The proposed utility development shall not cause or contribute to the release of stray electric current or voltage or static charge, or cause or contribute to the mobilization of toxic or hazardous substances or contamination of groundwater or surface waters, or result in a noxious fumes or hazardous materials on a Borough public or private roadway or on municipal or private property located within the Borough.

(11) 
To confirm that there is no negative impact to the Borough's transportation system or provision of emergency services, the utility service provider applicant shall submit referrals to the municipal police, ambulance corps, Fire Department, Office of Emergency Management, and local and regional Boards of Education, for review of the application, to determine that there will be no negative impact on emergency services. Affidavits showing that the necessary referrals have been made at least 30 days prior to the public hearing on the matter are required.
(12) 
In an effort to protect the desirable visual environment of the Borough, to prevent potential devaluation of lands within the Borough, and consistent with the purposes of zoning contained within the Municipal Land Use Law,[1] the utility development shall be visually buffered at all times of the year from all adjacent properties, including, but not limited to, public and residential property. Buffers shall provide a solid barrier from view of the utility development from adjacent residential lands and municipal open space or parks or from lands used for residential purposes. The only exception to this requirement is where the utility development and/or infrastructure is located on public lands or within the public rights-of-way and visual screening is deemed impracticable by the reviewing land use board. The maximum height of a solid, man-made barrier shall be no greater than that permitted in the zone district for fences. Visual mitigation may also include, but is not limited to, colorized or architecturally treated construction materials to visually blend with vegetated surroundings, mass evergreen or pine plantings, or other means deemed appropriate by the reviewing land use board. Buffers may be planted on adjacent residential properties to achieve the same barrier effect, with approval by the reviewing land use board and the property owner on which the buffer will be planted. Tree removal restitution shall be as prescribed in other sections of the Land Use Ordinance.
