Purpose. It is the intent of these regulations to prevent land or structures, including those permitted by right or conditional use, from being used, or occupied in any manner so as to create any dangerous, injurious, noxious or otherwise objectionable fire, explosive, radioactive or other hazardous condition; noise, or vibration; smoke, dust, odor or other form of air pollution; electrical or other disturbance; or other substance, condition or elements in a manner or amount as to adversely affect the surrounding area.

(B)

Other regulations. Compliance with the requirements of this section shall not be interpreted as authorizing any practice or operation which would constitute a violation of any other applicable statute, ordinance, rule or regulation. Where these regulations conflict with other regulations, the more stringent regulation shall apply.

No permits shall be issued for any use, activity or construction, which is subject to Louisiana Coastal Zone Management, Louisiana Wildlife and Fisheries, U.S. Army Corp of Engineers, Department of Environmental Quality (DEQ), and/or U.S. Environmental Protection Agency (EPA) approval, until after a public information hearing, on the proposed activity, has been conducted by the planning commission and all required permits and approvals have been issued by the herein stated federal and state reviewing agencies. The planning commission shall conduct its hearing within 30 days after the submittal of building plans and site plans. Said hearings shall be conducted at their regular monthly meeting. To be exempt from these regulations the owner or applicant of the property shall obtain written verification, from each of the herein listed federal and state agencies, that no permits or approvals are required. This hearing process in no way preempts the regulations and standards of the zoning ordinance or shall prevent the issuance of permits upon having obtained all required federal, state and local approvals. The hearing is to provide a means by which the public can become informed about a project and to present information that may be pertinent to the project. All pertinent environmental facts will be sent to the applicable federal and state agencies. Representative of the proposed business and the homeowners associations representatives involved shall be notified of the public hearing.

(C)

Administration and enforcement. All uses established in all districts shall conform in operation, to the performance standards herein specified.

(1)

The operator of a proposed use which has been determined will not comply with the standards contained in section 2.1901 may file an appeal with the board of adjustment. The board of adjustment in making its decision may require certain engineering and environmental analysis of the proposed operation by an independent consulting firm. The cost of such reviews shall be borne by the applicant.

(2)

Where a determination has been made that an existing use is in violation of the standards contained in section 2.1901, the operator may file an appeal with the board of adjustment. Such appeal shall be made on forms obtained from the department of planning and shall be filed with the department of planning within ten days of receiving a notice of violation from the city ordering all illegal operations to cease or be brought into compliance with the standards of the zoning ordinance. The board of adjustment in making its decision may require certain engineering and environmental analysis of the operation by an independent consulting firm.
