16 EXPRESS FINDINGS
A. Local Administrative Finding – This amendment is necessary for administrative clarification. It does not modify Building Standards pursuant to Sections 17958 and 1 8941.5 of the California Health and Safety Code and does not require an express finding to be made pursuant to Sections 17958.5 and 17958.7 of the Califor nia Health and Safety Code. This amendment establishes administrative standards for the effective enforcement of building standards and therefore needs to be incorporated into the code to ensure that new buildings and structures, as well as additions or alterations to existing buildings or structures, are designed and constructed in accordance with the scope and objectives of the Codes.
B. Local Geological Conditions – The City of Culver City is a densely populated area having buildings and structures constructed over and near a vast array of fault sys tems capable of producing major earthquakes, includ ing but not limited to the recent 1994 Northridge Earthquak e, the 1987 Whittier Narrows Earthquake, the 1971 S an Fernando Earthquake, and the 1933 Long Beach Earthquake. The proposed modification will reduce the failures, injuries, save lives, and minimize structural damag es and therefore needs to be incorporated into the code to ensure that new buildings and structures, and addit ions or alterations to existing buildings or struct ures, are designed and constructed in accordance with the scope and objectives of the Codes.
C. Local Climatic and Geological Conditions – The C ity of Culver City is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. In addition, the regi on is within a climate system capable of producing major winds, fire, and rain-related disasters, including but not limited to those caused by the Santa Ana winds and El Niño (or La Niña) subtropical-like weather. This region is especially susceptible to more active termite and wood-attacking insects and microorganisms.
D. Local Topographical and Geological Conditions – The City of Culver City is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northridge Earthquake. Additionally, the top ography within the City includes significant hillsides with narrow and winding access, which makes timely resp onse challenging and difficult. The hilly terrain with potential hazards such as slides, erosion, and local floods can be mitigated with the proposed amendments.
E. Local Climate Conditions – The City of Culver Ci ty is a densely populated area with buildings and s tructures located within heavily traveled traffic corridors and highways, near airports and ports, close to the ocean, and in flood-prone zones. This affects air quality, raises noise levels, and increases the risk of rising sea or flood levels.
The proposed modifications will help address and si gnificantly reduce local air and noise pollution, g reenhouse gas emissions, and enhance the health and welfare o f residents, businesses, and visitors. They will al so help prevent rising sea or flood levels from threatening homes, businesses, public facilities, airports, an d ports.
Therefore, this amendment must be integrated into t he code to ensure that new buildings, structures, a nd any additions or modifications to existing ones are des igned and built in accordance with the scope and ob jectives of the California Green Building Standards Code.
F. Local Climatic and Geological Conditions – The C ity of Culver City is a densely populated area having buildings and structures constructed over and near a vast array of fault systems capable of producing major earthquakes, including but not limited to the recent 1994 Northr idge Earthquake. The region is further impacted by the construction of buildings and structures that utilize traditional construction materials, which affect the amount of energy, air quality, greenhouse gas emissions, and construction waste in the area. The proposed amendm ent addresses structural designs specific to intermodal shipping containers, reduces the environmental imp act of unused and unrecycled intermodal shipping container s, and increases sustainability by reducing the consumption of traditional construction materials. The proposed modification needs to be incorporated into the code to ensure that new buildings and additions to existing buildings utilizing intermodal shipping containers are designed and constructed in accordance with the sco pe and objectives of the California Building Code a nd California Green Building Standards Code.
17 G. Local Climatic Conditions: The City of Culver Ci ty is a densely populated area in Southern Californ ia that experiences extended drought conditions and dry seasonal winds. These severe droughts negatively impact the local water supply, and the dry seasonal winds heig hten the fire risk within very high fire hazard sev erity zones by causing vegetation to dry out excessively. During a fire, these winds can carry burning embers from structures and vegetation to other buildings, potentially caus ing fires to spread. This amendment is necessary to address local water shortages, reduce water waste, enhance groundwater recharge, and mitigate the risk of fire spread associated with reduced water supplies and wind-driven fires.
H. Local Geologic and Climatic Conditions: The City of Culver City is a densely populated area affected by various sources of pollution that impact local air quality, visual light quality, and landfill waste. Local cl imatic conditions cause atmospheric inversion of trapped air, which enhances the adverse effects of particulate and light pollution that are reflected back to earth. Due to the high groundwater levels in the Los Angeles Basin, pollutants leaching from landfill waste can contaminate critical ground water reserves. Air pollutants from automobiles neg atively affect pulmonary function and may contribute to lon g-term health issues. Light pollution from excessiv e or improperly aimed nighttime lighting can disrupt hum an sleep patterns and disturb healthy circadian rhy thms.
Excessive disposal of construction and demolition w aste increases pollutants in groundwater beneath la ndfills and results in higher greenhouse gas emissions as b uried waste decomposes. This amendment is necessary to mitigate environmental pollution by reducing gas-powered vehicle trips, landfill waste, and excessive outdoor lighting.
I. Local Climatic and Environmental Conditions: The City of Culver City is a densely populated city wi th a local emergency on homelessness, as proclaimed in 2023. C ity-wide and State-wide housing development is a ke y component in addressing this emergency. The City’s General Plan establishes policies related to infill development to enhance the region's housing and climate initiatives. The General Plan’s Land Use (LU) Specific Element Goals LU-3.3, LU-3.4, encourage infill development standards to support housing development on small mixed-use lots. Goal LU-4.2 encourages creativity a nd flexibility in development standards on opportun ity sites to facilitate a mix of uses and support complementa ry, community-serving uses, such as gathering space s.
Goals LU-13.1, 13.2, and 13.5 encourage multifamily housing development within neighborhoods designate d for higher-density residential, and modify existing development standards that prevent the development of small sites. These Goals promote the development of green buildings, using sustainable construction, and encourage positive climate impact.
The City of Culver City is a densely populated area having buildings and structures constructed within heavily traveled traffic corridors and highways, near and within the proximity of airports and/or ports, near the ocean, and within flood-prone areas. This impacts the quality of the air, causes a higher decibel noise level, and increases the risk of rising sea or flood levels.
The Terner Center for Housing Innovation, at UC Berkeley, (Terner) compared cities demonstrating that infill development reduces Vehicle Miles Traveled, reduces Daily Travel Distance, reduces Passenger Vehicle Greenhouse Gas Emissions, and increases the number of Daily Trips by walking, biking, or using transit.
These findings are similar in Culver City, given access to mass public transportation, the availability of employment opportunities, and the abundance of shop ping and dining establishments. Terner suggests that infill of more housing is likely to yield large reductions in pollution, which is critical for meeting the state’s climate goals.
The proposed modifications will help to address and significantly reduce local air and noise pollution, greenhouse gas emissions, waste, heat island effects, and improve the health and welfare of the region ’s residents, businesses, and visitors, and reduce the rise in sea or flood levels that could put at risk the region’s homes and businesses, public facilities, airports, and/or ports. Therefore, this amendment needs to be incorporated into the code to ensure that buildings are designed and constructed in accordance with the scope and objectives of the California Building Code and the California Green Building Standards Code.
