This chapter shall be known as the "Grading Ordinance of the city of Lemon Grove."
(Ord. 371 § 1, 2008; Ord. 428 § 1, 2015)
This chapter establishes minimum requirements for grading, excavation and filling of land. It also provides for the issuance of permits, and provides for the enforcement of the chapter provisions. These provisions are supplementary and additional to the subdivision and zoning regulations of the city and shall be read and construed as an integral part of such regulations and the land development patterns and controls established thereby.
(Ord. 371 § 1, 2008; Ord. 428 § 1, 2015)
The intent of this chapter is to protect life and property, promote the general welfare, enhance and improve the physical environment of the community, and preserve and protect the natural scenic character of the city. In administering these provisions, the following goals should be respected:
A. 
Ensure that future development of lands occurs in the manner most compatible with surrounding natural areas to have the least adverse effect upon other persons, land, or the general public;
B. 
Ensure that soil will not be stripped and removed from lands leaving barren, unsightly, unproductive land subject to erosion, subsidence and faulty drainage;
C. 
Encourage design and development of building sites to provide the maximum in safety and human enjoyment, while adapting development to and taking advantage of the natural terrain; and minimizing adverse visual impacts caused by major land form modifications;
D. 
Encourage and direct special attention toward retaining natural plantings and maximum number of existing trees;
E. 
Ensure that the objectives and policies of the adopted general plan for the city are met;
F. 
Meet the requirements of San Diego Regional Water Quality Control Board Order Number R9-2013-0001, as may be amended.
(Ord. 371 § 1, 2008; Ord. 428 § 1, 2015)
A. 
Nothing in this chapter shall preclude the inclusion in any zoning permit, subdivision approval, waiver, review or other approval issued or approved pursuant to city ordinances of any condition, provision or requirement concerning the grading of land. Nothing in this chapter shall preclude the requirement for the property owner or applicant to obtain any other permit or approval required by the city engineer or by law from any public or private party or agency.
B. 
This chapter shall not affect the requirements of any other provision of this code requiring permits, fees or other charges, or affect any provision concerning the granting of franchises by any other person, body or agency.
C. 
This chapter is intended to implement the provisions of Chapters 8.48 and 8.52 of this code related to stormwater regulatory requirements including compliance with all implementing regulations of the city related to pollution control related to stormwater discharges, such as the Lemon Grove jurisdictional runoff management program ("JRMP").
