2022 Program Component #1:�Ordinance Requiring All-Electric New Buildings
Extended Regulatory Flexibility
The draft ordinance (Attachment B) amends Municipal Code Section 17.70.095 to extend the provision of temporary incentives in the application of site development standards for new all-electric buildings.
�Other Incentives

2022 Program Component #2:�Incentive Program Including Ordinance Extending Regulatory Flexibility
Public Health and Safety Findings
Solar EV charger at City Hall
Climate Change. Drastic reductions in greenhouse gas emissions from all sectors, including buildings, are necessary to prevent increasingly hazardous climate disasters. A rapid reduction in natural gas is particularly important.
Seismic Safety. Buried gas pipelines are vulnerable to earthquakes and can leak or break due to strong shaking, ground transformation, or liquefaction, which can cause explosions and fires if ignited.
Indoor Air Quality. Natural gas combustion produces toxic byproducts that accumulate indoors and has been linked to an increase in respiratory diseases
Resilience Considerations
Solar EV charger at City Hall
Nearly all contemporary natural gas appliances require electricity to ignite and operate safely.
A resilient electrical grid is critical to community well being regardless of Council’s action.
Organizations at all levels of government and scale are aggressively pursuing grid resilience efforts.
Equity & Cost Effectiveness

Met with local affordable housing providers and developers on their experience building and managing all-electric projects
Promote access to Central Coast Community Energy’s all-electric affordable housing unit incentive program
Evaluation of existing and initial future cost-effectiveness studies to confirm that all-electric buildings are expected to be cheaper to build than mixed-fuel buildings
