(A) Resource and mineral extraction operations must meet the following development standards:
(1) Excavation, washing, and stockpiling of extracted material shall not be carried on closer than 50 feet to any property line, or such greater distance as is deemed necessary for the protection of adjacent property, except that this distance requirement may be reduced by the written consent of the owner of abutting property, but in any such event, adequate lateral support shall be provided for the abutting property.
(2) In the event that the site of the mining operation is adjacent to the right-of-way of any public street or road, no part of such operation may take place closer than 50 feet to the nearest line of such right-of-way.
(3) Any excavated area adjacent to the right-of-way of any public street or road shall be back-filled for a distance of 150 feet from the right-of-way line.
(4) Fencing or other suitable barrier, including acceptable plantings, shall be erected and maintained around the entire site or portions thereof.
(5) All equipment and machinery shall be operated and maintained in such manner as to minimize dust, noise, and vibration. Access roads shall be maintained in a dust-free condition by surfacing or other treatment.
(6) Quarrying shall not be carried out closer than 300 feet to any adjoining property line unless the written consent of such adjoining property owner has first been obtained.
(7) An earthen mound sight and sound barrier of a minimum of eight feet in height shall be provided to assure compatibility with adjoining land uses. The barrier shall be suitably planted and maintained.
(8) Rehabilitation requirements. All mined-out areas shall, within a reasonable length of time, be reclaimed and rehabilitated. Within six months after completion of mining operations, the company shall provide the city with a written plan indicating its intentions relative to equipment and structure removal and the approximate date and time frame for reclamation and rehabilitation of the mined-out area.
