17.144.010 Purpose.

The intent of the M-3 district is to reserve appropriate locations consistent with the General Plan to accommodate a full range of mineral resource extraction and related manufacturing in order to strengthen the City’s economic base and to increase employment opportunities. Locations for the M-3 district may have operational characteristics or features that make their location near less intensive uses or highly visible areas of the City inappropriate. However, uses which have nuisance features that cannot be mitigated or which pose a threat to public health or safety shall not be permitted. This chapter includes appropriate development criteria to assure a quality of appearance of all structures and uses from public rights-of-way in order to encourage the long term viability of the district as well as to attract desirable users. This chapter also contains the appropriate standards and criteria to ensure public health and safety. [Ord. 1150 § 2, 2005. Code 1987 § 17.61.010].

17.144.020 Permitted uses without a mining or conditional use permit.

Uses permitted in the M-3 district shall include those businesses listed below which operate in compliance with the purpose, intent and standards of this district, are conducted on a contiguous area of not less than 300 acres unless otherwise permitted in LEMC 17.144.030, maintain an exterior environment meeting all State and Federal regulations pertaining to odor, dust, smoke, gas, noise, vibration, electromagnetic disturbance, and the storage of hazardous waste. Each business shall be evaluated in terms of its operational characteristics and specific site location pursuant to the provisions of LEMC 17.415.050 and 17.415.060.

A. All permitted uses in the M-1 district listed in LEMC 17.136.020.

B. All permitted uses in the M-2 district listed in LEMC 17.140.020.

C. Agricultural uses of the soils for crops, orchards, grazing and forage.

b. Between 300 feet and 500 feet of the property boundary shall be screened to a height of at least six feet by either landscaping, berms, walls or solid fencing and the outer boundaries of the area being excavated shall be enclosed with a six-foot-high chain link fence, including all necessary gates, except where such a fence would be impractical, as in the bed or flood channel of a wash or watercourse, because of differences in elevation.

2. For Excavation Operations.

a. Within the requisite 150-foot setback of the property boundary – prohibited without issuance of a conditional use permit.

b. Between the requisite 150-foot setback and 500 feet of the property boundary shall be screened to a height of at least six feet by either landscaping, berms, walls or solid fencing and the outer boundaries of the area being excavated shall be enclosed with a six-foot-high chain link fence, including all necessary gates, except where such a fence would be impractical, as in the bed or flood channel of a wash or watercourse, because of differences in elevation.

G. Hours of Operation. Subject to the exceptions expressed herein and except for preexisting operations, all uses shall confine operations on the property to the hours between 7:00 a.m. and 7:00 p.m., Monday through Saturday, and uses shall not be permitted on legal holidays or Sundays.

1. Subject to issuance of a conditional use permit, those operations that are located between the requisite 150-foot setback for residential zoned property (LEMC 17.144.070) and 500 feet from the outer boundary of the property may engage in continuous activities beyond the hours of operation.

2. Those operations (both excavation or manufacturing operations) that are located more than 500 feet from the outer boundary of the property may engage in continuous activities beyond the hours of operation so long as the activities otherwise comply with the substantive requirements of the Lake Elsinore Municipal Code, including the specific standards set forth in this chapter.

H. Insurance. Before commencing any mining operations in accordance with this chapter, including production activities or operations incident thereto, the owner or operator shall provide evidence of liability insurance in an amount of $1,000,000 per occurrence and $2,000,000 in the aggregate or such other amount as may be reasonably acceptable to the City.
