Project Goals + Process

WHERE?

• Santa Clara County (1.9 million residents as of 2013) is consistently ranked amongst the top regions for growth in employment, personal income, and real taxable sales.

• It is the 4th most ethnically diverse metro area in the U.S.

• Median age is 36.7

• Highly desirable place to live and conduct business

• Gross domestic product has exceeded $200 billion

• Property tax assessment rolls have exceeded $350 billion

• The region accounts for more than 75% of all California venture capital investment (and roughly 40% of the national investment) and 12%+ of all patents filed nationally

• 29 regional parks covering roughly 48,000 acres

• Farmers and ranchers in Santa Clara County grow 100 different crops and contribute $250 million to the local economy each year

THE VALLEY OF HEART’S DELIGHT & SILICON DREAMS

WHY?

• Climate change presents a complex and uncertain challenge requiring the dedication and action of multiple actors and agencies at all levels

• Increasing atmospheric greenhouse gas concentrations = local climate condition changes: sea level rise + storm surge (36 to 66 inches by end-of-century), increased riverine flooding, and more frequent / higher temperatures (extreme heat events and wildfires) + drought.

• Potential impacts to critical assets throughout the county: regionally significant highways and local roadways, water and wastewater treatment plants, electricity substations, technology campuses and other employment centers, homes, vulnerable populations, and ecosystems

• Human health consequences negatively impact the economy, external and indoor air quality, productivity, inflate personal costs and budgets

• Threatens biological diversity, vigor, and vitality

• The interest in retaining corporate citizens and attracting new businesses

10

SILICON VALLEY 2.0 GOALS

• Identify assets threatened by climate change and the magnitude of the potential economic, social, and environmental impacts using a robust vulnerability and risk management framework

• Develop the SV 2.0 Climate Change Preparedness Decision Support Tool (Tool) to evaluate the vulnerability and consequence to key assets from potential climate change

• Identify potential adaptation strategies to minimize climate impacts

• Identify the region’s top priorities and the near-term actions needed to implement an effective regional-scale adaptation response

• Facilitate and coordinate regional climate adaptation planning. Coordination, and implementation efforts for Silicon Valley

• Create a set of resources capable of being used and replicated statewide

WHICH OBJECTIVES AND OUTCOMES

WHAT IS IT? WHAT IT IS NOT!

• A multi-year, multi-stakeholder process and extensive regional effort

• Designed and managed by the Santa Clara County Office of Sustainability and funded by the State’s Strategic Growth Council

• A Decision-Support Tool designed for flexibility, expansion, replication

• A suite of resources to minimize the anticipated impacts of climate change within the County boundary (15 cities + unincorporated portions of the County)

• A living Guidebook that provides a recommended set of short, mid, and long term strategies for implementation

• Helps establish a proactive framework for collaboration between the County, cities, agencies, stakeholders (State and federal authorities, private landowners, et al)

Not designed as a “plan” to be adopted by one or many jurisdictions

25 SV 2.0 TOOL: VULNERABILITY ASSESSMENT

26

VULNERABILITY ASSESSMENT

• Analyses the vulnerability of each asset sector to each climate variable

• Comprised of three parts:

(1) Exposure analysis

- Based on GIS overlays of asset locations + climate variables

(2) Sensitivity analysis

- Sensitivity ratings (i.e. the impact of a climate variable on the asset’s functionality) defined from literature reviews, expert interviews, and input from the TAC and other technical experts

(3) Adaptive capacity

- Based on literature gap analysis

METHODOLOGY

27

VULNERABILITY ASSESSMENT EXAMPLE

• Exposure analysis: GIS based (from Caltrans, 2013)

• Sensitivity analysis:

- High: roads permanently inundated

- Medium: traffic delays

• Adaptive capacity: Low

• Make sense to initiate in the next 5–10 years?

• Fall within local or regional government, or agencies jurisdiction to implement?

• Allow for use by more than one jurisdiction or agency?

• Address the vulnerability of multiple assets?

• Address critical facilities or lifeline routes?

• Reduce consequences on society/equity?

• Provide a positive impact on habitat protection or restoration?

• Require very high upfront capital cost, and therefore require complex financing arrangements?

• Provide a positive impact on the economy?

Economic Consequences

36

ECONOMIC CONSEQUENCES

» FRAMEWORK

• Economic consequences of a mid-century climate change scenarios on today’s assets (no adaptive measures have been taken)

• Expressed in order of magnitude ratings

» CRITERIA

• Most applicable to SV 2.0 assets and quantifiable with available data sources:

o Replacement cost

o Loss of fiscal revenue

o Change in operational cost

o Interruption of economic activity

METHODOLOGY

37


» ANALYTIC LIMITATIONS

• Assessed four economic criteria that best apply to physical asset sectors and have available data;

• Other potential economic consequences were not assessed due to lack of available data, such as cost of decreased health, loss of ecosystem services, and higher utility (energy and water) rates;

• Assets and climate variables are largely considered independently of each other, so this analysis does not fully capture the potential for cascading or cumulative economic impacts;

• Therefore: economic consequence findings should be considered low estimates -- further study required to achieve more comprehensive estimates, including total societal and environmental consequences.

METHODOLOGY

38

» RATING SCALE (ACROSS ALL 4 CRITERIA)

• Dynamic rating scale uses percentages of economic loss that can be applied across different criteria and jurisdictions.

• Uses the economic loss experienced in Santa Clara County during the 2008–2009 recession as the threshold for an “extreme” economic consequence rating (i.e., 8% of jobs were lost).

Low 0.0% to less than 0.1%

Moderate 0.1% to less than 0.3%

High 0.3% to less than 1.6%

Very High 1.6% to less than 8%

Extreme 8% or greater

Ranges of Percent Economic Loss for Ratings

ECONOMIC CONSEQUENCES METHODOLOGY

39

• Rating scale for Replacement Costs, Interruption of Economic Activity, and Operational Costs based on estimated Countywide GDP

• Rating scale for loss of fiscal revenue based on estimated County and local jurisdiction property and sales tax revenue

• NOTE: all values = 2014$
