For purposes of floor area calculations, Group U (attached private garages or similar) occupancies shall be included in the floor area calculation.

 

Section 3: Findings of Certain Local Climatic, Geographical, or Topographical conditions

 

Pursuant to Sections 17958.5 and 17958.7 of the California Health and Safety Code, the City Council finds that the modifications of the 2022 Edition of the California Green Buildings Standards Code and the 2022 Fire Code is reasonably necessary because of certain local climatic, geographical, or topographical conditions existing in the City of Alameda, which are more specifically described as follows:

 

Climatic: The City is located in Climate Zone 3 in the 2022 Edition of the California Energy Code. Alameda is already experiencing the repercussions of excessive greenhouse gas emissions including increased temperatures and more extreme weather events, decreased precipitation, and impacts of increased wildfire risk. These climatic conditions, along with the greenhouse emissions generated from structures in both the residential and non-residential sectors, lead to severe environmental impacts and accordingly require Alameda to exceed the energy standards for building construction established in the 2022 Edition of the California Buildings Standards Code. The City Council adopted a Climate Action and Resiliency Plan that has a goal of reducing greenhouse gas emissions 50% below 2005 levels by 2030. In order to make progress in achieving this goal, the City needs to adopt policies and regulations that reduce the use of fossil fuels that contribute to climate change, such as natural gas in buildings, in new and existing development. Burning natural gas to heat buildings releases greenhouse gases into the atmosphere and causes an overall increase in global average temperature. These conditions contribute to sea level rise and increasingly destructive wildfires, affecting the City’s shoreline and infrastructure, in addition to the health of its residents. Additionally, Alameda Municipal Power provides 100% clean energy, allowing all-electric buildings to be carbon free in their operations.

 

Seismic/Geologic: Alameda is subject to earthquake hazard caused by its proximity to both the Hayward and San Andreas faults. Both of these faults are considered active faults which may rupture at any time. The USGS estimates that an earthquake greater than magnitude 6.7 has a 72 percent chance of occurring in the Bay Area before 2043. An earthquake on one of these faults will likely result in widespread liquefaction damaging buildings and buried infrastructure. Reducing the reliance on natural gas in new construction will decrease the risk of fires when gas lines rupture and break or gas appliances topple in earthquakes. Restoring full natural gas service following a major earthquake may take up to six months, compared to about two weeks for electricity. Furthermore, proximity to several earthquake faults, including the Hayward and San Andreas faults make buildings and structures vulnerable to structural ruptures and subsequent fires. Many of the buildings and structures in Alameda include relatively old housing stock and unique historic commercial buildings that were generally constructed without the benefit of modern Building Code requirements to strengthen them against seismic events. The likelihood of occurrence of secondary effects due to ground shaking in Alameda is high due to underlying soil conditions in Alameda, such as artificial fill, bay mud, and expansive soils. The entire municipal water supply for the City of Alameda is transported via three aqueducts which are vulnerable to earthquake and tidal flooding. Major fires resulting from the rupture of local gas or electric lines during an earthquake could be severely compounded by water main failures and substandard fire protection systems in older buildings.

Topographic: The City of Alameda is a low-lying island in the San Francisco Bay, with a rising groundwater table associated with sea level rise which can cause flooding and damage buried infrastructure.  As an island community with access dependent upon bridges and underwater tubes that could make access in the event of a disaster a challenge. With access dependent upon bridges and underwater tubes which are not expected to survive a major seismic event, Alameda could be completely isolated from outside assistance, exacerbating fire and life safety concerns.

 

 

Section 4:                     IMPLIED REPEAL

 

Any provision of the Alameda Municipal Code inconsistent with this Ordinance, to the extent of such inconsistencies and no further, is hereby repealed or modified to the extent necessary to effectuate this Ordinance.

 

Section 5:                     CEQA DETERMINATION

 

Adoption of the Ordinances amending the AMC is not a project under California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines section 15378 and Public Resources Code section 21065 because it does not: (1) approve a project or result in a direct physical impact on the environment, or (2) contemplate known future projects, and as such, no known environmental impacts are known at this time. Instead, the proposed amendments would clarify procedural aspects related to the implementation of locally adopted building and other related codes.

 

As a separate and independent basis, adoption of the Ordinances amending the AMC is exempt from CEQA pursuant to CEQA Guidelines section 15061(b)(3) because it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment.

 

Section 6:                                          SEVERABILITY

 

If any provision of this Ordinance is held by a court of competent jurisdiction to be invalid, this invalidity shall not affect other provisions of this Ordinance that can be given effect without the invalid provision and therefore the provisions of this Ordinance are severable.  The City Council declares that it would have enacted each section, subsection, paragraph, subparagraph and sentence notwithstanding the invalidity of any other section, subsection, paragraph, subparagraph or sentence.

 

 

 

Section 7:                                          EFFECTIVE DATE

 

This Ordinance shall be in full force and effect from and after the expiration of thirty (30) days from the date of its final passage.
