Editor's note— Sec. 7 of Ord. No. 1521, adopted Oct. 24, 2017, rescinded Ch. 1, which consisted of §§ 91701.00—91701.09, and derived from the prior code. Sec. 8 of said ordinance re-enacted Ch. 1 to read as herein set out.
91701.00 - Purpose and intent.¶
A. The purpose of these regulations is to facilitate the beneficial use of renewable energy resources for the general welfare of the people of Imperial County and the state of California; to protect renewable energy resources from wasteful or detrimental uses; and to protect people, property, and the environment from detriments that might result from the improper use of renewable energy resources.
B. It is the intent of these regulations to implement the renewable energy overlay zone established in the renewable energy and transmission element, and integrate, to the extent possible, Imperial County's regulations with those of other governmental agencies which regulate renewable energy development.
C. It is further the intent of these regulations to provide for the protection of the public health, safety and general welfare as the result of changes in the regulations or enforcement policies of those other agencies which regulate renewable energy development.
(Ord. No. 1521, §§ 7, 8, 10-24-17)
91701.01 - "RE" renewable energy overlay zone.¶
The renewable energy (RE) overlay zone consists of two categories as shown on the RE overlay map:
A. The geothermal energy overlay for areas where existing and future development has been environmentally review for geothermal renewable energy facilities; and
B. The renewable/geothermal overlay for areas that could be developed with any form of renewable energy technology, including geothermal production.
Land classified in some other (non-overlay) zone may also be classified in the "RE" renewable energy overlay zone. An amendment to the overlay zone would only be approved by the county board of supervisors if a future renewable energy project met one of the following two conditions:
•
Adjacent to the Existing RE Overlay Zone: An amendment may be made to allow for development of a future renewable energy project located adjacent to the existing RE overlay zone if the project:
º
Is not located in a sensitive area.
º
Would not result in any significant environmental impacts.
•
"Island" Overlay: An amendment may be made to allow for development of a future renewable energy project that is not located adjacent to the existing RE overlay zone if the project:
º
Is located adjacent (sharing a common boundary) to an existing transmission source.
º
Is adjacent to or within one-quarter mile of an existing operating solar facility.
º
Would not result in any significant environmental impacts.

91701.03 - Conditional use permits.¶
Renewable energy projects must be located within the renewable energy overlay zone and may be permitted only through the issuance of a conditional use permit (CUP) within applicable zones as approved by the approving authority unless otherwise allowed by applicable law. Renewable energy projects may consist of the following technologies: geothermal, solar, wind, deep solar ponds, biofuel, bio-mass, algae production, concentrated solar-thermal power, and concentrated photovoltaics.
(Ord. No. 1521, §§ 7, 8, 10-24-17)
