Section I Findings

The Board finds and declares that the adoption of this Ordinance is necessary and appropriate to implement state law and the policies and programs of the Sonoma County General Plan, to ensure neighborhood compatibility, protect the general welfare of residents in the County, and facilitate the development of alternative energy sources. The Board hereby finds that the facts supporting the adoption of this Ordinance are as follows:

  1. The State of California enacted the Global Warming Solutions Act, Assembly Bill 32 (AB 32) in 2006 which requires a reduction in California's greenhouse gas (GHG) emissions to 1990 levels by 2020, and the County of Sonoma has adopted a bold goal of reducing GHG by 25 percent below 1990 levels by 2015.
  2. The County has adopted a Community Climate Action Plan which identifies a number of actions to be taken in order to address the AB 32 requirements and the County’s GHG reduction goals by 2015.
  3. The Sonoma County General Plan contains numerous policies and programs within its Open Space and Resource Conservation Element and its Circulation and Transportation Element that will be supported and implemented with the adoption of the ordinance amending the Zoning Code. The proposed ordinance is consistent with the goals, policies and objectives of the General Plan, including the proposed amendment to ORSC-15D and the Glossary.
  4. This ordinance provides specific measures to identify and facilitate development of a variety of alternative energy systems and provides clarification on standards for placement, construction, operation and maintenance of renewable energy systems, as well as making provisions for density bonuses and parking allowances, in order to encourage and facilitate the provision of new distributed energy systems and to reduce uncertainly in the permitting process for new renewable energy production facilities .
  5. Based upon the information contained in the Initial Study dated September 11, 2012 and included in the project file, it has been determined that there will be no significant environmental effect resulting from this project, and a Negative Declaration has been prepared. The Negative Declaration has been completed, reviewed, and considered, together with comments received during the public review process, in compliance with CEQA and State and County CEQA Guidelines, and reflects the independent judgment and analysis of the Board.

Section II Chapter 26, Zoning, of the Sonoma County Code is amended as follows:

Section 26-02-140, Definitions, is amended to incorporate the following definitions, in their alphabetical locations:

Accessory renewable energy system: An on-site renewable energy system, including but not limited to wind, bioenergy, solar, low-temperature geothermal heating systems, geothermal heat pump systems, and fuel cells and combinations thereof, where the energy generated is used primarily to meet the energy demands of the lawful use on the property where the system is located. Accessory renewable energy systems are subject to the applicable general development standards set forth in 26.88.200 A.

Biodiesel: A liquid fuel intended for consumption by compression ignition engines that is produced by chemical modification of plant oil, animal fat, or algae feedstock.Production involves reacting the feedstock with an alcohol such as ethanol in the presence of a catalyst.

Bioenergy: Renewable energy made available from materials derived from from feedstocks that consist of recently living organisms or their metabolic by-products from sources such as farming, forestry, and biodegradable industrial and municipal waste.

Capacity (Electrical): The maximum amount of electricity that a generating unit, power facility, or utility can produce under specified conditions. Capacity is measured in kilowatts (KW) or megawatts (MW).

Co-generation: The successive production of electrical or mechanical energy and useful heat energy.

Commercial renewable energy facility: An energy generation facility using renewable fuel sources, including but not limited to wind, bioenergy, solar, geothermal, and fuel cells and combinations thereof, where the energy generated is used to meet off- site energy needs. Commercial renewable energy facilities are subject to the general development standards set forth in 26.88.200.B. as well as any applicable Special Use Regulations.

Community Choice Aggregator (CCA): As defined in Public Utilities Code Section 331.1 refers to any of the following entities, if that entity is not within the jurisdiction of a local publicly owned electric utility that provided electrical service as of January 1, 2003: any city, county, or city and county whose governing board elects to combine the loads of its residents, businesses, and municipal facilities in a community wide electricity buyers’ program or any group of cities, counties, or cities and counties whose governing boards have elected to combine the loads of their programs, through the formation of a joint powers agency established under Chapter 5 (commencing with Section 6500) of Division 7 of Title 1 of the Government Code.

Distributed energy system or facility: A small-scale electricity generation system or facility that is interconnected to the distribution network. Distributed energy systems primarily serve on-site uses, while distributed energy generation facilities generate power for both on- and off-site power needs.

Emerging renewable technology: Technology that uses a renewable power source, such as solar or wind energy, to generate electricity, and that has emerged beyond the research and development phase, is commercially available, and has significant commercial potential as determined by the Energy Commission. Emerging renewable technologies include photo voltaic, solar thermal electric, fuel cells using a renewable fuel, and small wind turbine technology no greater than 50 kilowatts in size.

Fuel Cell: An advanced energy conversion device that combines hydrogen-bearing fuels with airborne oxygen in an electrochemical reaction to produce electricity very efficiently and with minimal environmental effects.

Geothermal: Natural heat from within the earth, captured for production of electrical power.

Hybrid alternative energy facilities: An alternative energy system using one or more renewable fuel sources to provide electricity, gas, or heat energy. Batteries or fuel cells may be a part of a hybrid alternative energy facility.

Important farmland: Lands mapped by the state Farmlands Mapping and Monitoring Program (FMMP) as Prime Farmland, Farmland of Statewide Importance, or Unique Farmlands. Does not include lands mapped by the FMMP as Farmlands of Local Importance unless specifically noted.

Megawatt (MW): 1,000 kilowatts. (Example) One megawatt is about the amount of power needed to meet the energy demands of up to 750 homes.)

Net metering: Contractual agreement or tariff wherein the system owner/generator produces more electricity than is needed to serve the on-site electrical load, and the surplus electricity is supplied to the electrical distribution grid. The owner/generator’s utility meter records the difference, or net, between what the utility supplies to the owner/generator and what the owner/generator supplies to the grid.

Photo-voltaic (PV): A technology that uses a semiconductor to convert sunlight directly into electricity.

Solar energy system: An system of photo-voltaic cells, panels or arrays designed to collect and convert solar power into energy for on-site use. See also Accessory Renewable Energy System.

Solar thermal electric: The conversion of sunlight to heat and its concentration and use to power a generator to produce electricity. Typically, solar concentrators boil water with focused sunlight, generating high-pressure steam which drives conventional turbine generators.
