Challenge #1: Water Not Enough

Over two-thirds of the Bay Area’s water supply comes from Sierra Nevada snow pack

Climate Change leads to more extreme rain and snowfall events, droughts, sea level rise

Challenges → Opportunities (Risks)Risk Issue Current Problems

SLR Climate Change

3 ft SLR risk amounts to a $50B risk in Bay Area (270,000 people) and 31 major

businesses in SV.

Flooding Imperviousness Due to channelization and low amount of green (tree) coverage ~80% impervious

Transportation Modes of Transport Results in loss of resources (time, fuel, money) due to extreme congestion

Air/Noise

Pollution

Lack of Green Space

Pollution from 237 and from southward winds from north bay and lack of green

space for filtration.

Extreme Heat Climate Change Estimated 3-6 °F increase by 2100 (400% increase in Extreme Heat Days)

Energy Renewables 100% renewables by 2050 in CA result in new production of renewable energy

Public Appeal Culture & Recreation

Lack of cultural aspects in South Bay results in increased population commuting

from SF.

People PlanEnergy & Transportation

Biofuel/Biogas ProductionSunnyvale wastewater plant serves 148,000 people

14,800,000 gallons/day (100 gallons per day per person)

13,000 gallons of biofuel/day→ Enough for 2000 people/day

PV SolarTake a two-pronged strategy to implement utility and commercial rooftop solar PV.

Utility Production:

Lower: 1.25 million sqft available (116,000 sqm)

→ 50 GWh/year → $6 million/year

Upper: 1.3 million sqft available (121,000 sqm)

→ 52 GWh/year → $6.2 million/year

Total (feasibly): 40 GWh/year → $5 million/year

PV SolarTake a two-pronged strategy to implement utility and commercial rooftop solar PV.

Commercial Production:

Policy implementation to require rooftop

solar or green roof on each commercial

structure in Study Area.

NW: 200,000 sqft available (18,600 sqm)

→ 6 GWh/year → $700,000/year

SE: 250,000 sqft available (23,000 sqm)

→ 7.3 GWh/year → $900,000/year

Total (feasibly):

5 GWh/year → $600,000/year

PV SolarAssuming 18 kWh/sqft/year

(commercial space), Study

Area PV production

conservative estimates will

provide enough power for

the entire Intervention Site

(1.25 million sqft) two

times over!

Energy EfficiencyPolicy-based to promote energy

efficiency in buildings, requiring

LEED Gold certification for each

building.

LEED Gold energy savings average

around 25%, which translates to a

total of 8.1 million kWh to 6

million kWh, 2.1 million kWh/year

or $250,000 annually.

TransportationDriving/Parking

Driving accessible through main streets, including access to 237 via Java Dr.

Pull-off/temp parking roundabouts ideal for quick pick-up/drop-off (Uber/Lyft)

Parking provide multipurpose infrastructure as underground parking, green space, and flood detention

Each green parking lot is accessible with underground ramps from each roundabout.

TransportationWalking & Biking

Public car-free zones to encourage pedestrian region.

1.8 million sqft of walkable, bikeable pathways.

Extensive bike share system for easy connection from car/public trans to bike.

TransportationConnections

Bringing employees from major tech companies in surrounding areas.

Bringing residents from south of 237 (Go Team Red!) and east of the East Channel.
