Resilience comes at a cost.
Strategies to increase redundancies reduce efficiencies, so you can’t get to your maximum yield in the form of short‐term gains.
As long as things don’t go wrong, it’s more profitable to run down your resilience.

"Vehicle Miles Traveled"
Travel Less • Congestion pricing • Denser, Mixed‐Use Land Uses • Increased parking rates • Increased cost of gasoline • Increased cost of vehicles & maintenance • Telecommuting options • Flexible work hours • Internet shopping/delivery
Travel Differently • Offer options! • If people don’t have options, they can’t use them. • Options needs to be comfortable, accessible, and well‐connected.

Pro’s • Off the grid energy • No moving parts • Low maintenance • Long life • Noncorroding parts • Easy installation • Modular design • Universal application • Safe low‐voltage output • Simple controls • Long‐term payback
Con’s High initial cost Requires direct sunlight Sensitive to shade Lowest output during shortest days Low‐voltage output difficult to transmit |

Wind Energy Positives: o Wind power generates electricity without the air quality impacts. o Wind turbines don’t need water for cooling so can be located in hot, arid climates without using up the limited water supply. o Renewable & Local
Wind Energy Negatives: o Bird & bat collisions o Noise o Shadow flicker o Blade/ice throw o Visibility
Standards can be put in place to address these issues, making wind can be a very viable option.

Geothermal Energy Benefits: o Energy savings up to 70% o Quiet operation o Even heating – no blasts of hot air o Low maintenance o Long life o No flames, fumes or combustion o No outdoor tanks, like propane o Environmentally friendly o Energy Security ‐ produced in the U.S./locally
Negatives: o Expensive! |

Hydropower Positives o Clean fuel source; Doesn't pollute the air o Domestic source of energy, produced in the U.S. o Renewable power source o Available as needed ‐ flow of water can be controlled to produce electricity on demand.
Hydropower Negatives o Disruptions to water temperature and composition o Impair species migrations routes o Changes to natural water flow and intensity (including peak flood seasons) o Can kill water species o Mechanical fluids can leak out, which may be harmful to the marine life nearby. o Noise pollution on the marine environment o Visible aesthetics o Salt water causes corrosion in metal parts; difficult to maintain tidal stream generators due to their size and depth in the water. |

Water Conservation
- Reduces water demand
- Focuses on increasing efficiency
- Utilizes wastewater reclemation to meet nonportable demand
|

Definition
- Green roofs provide insulation, absorb rainwater, create habitat and lower air temps
- Green dev. Rain gardens allow runoff to be absorbed, improves water quality and reduces pollutants

Definition
- Gray water can be used for agriculture, fires or put back into system
- Decentralized systems. Natural systems or onsite treatment. instead of big treatment plants
- Natural systems. Run water over permeable grassy slopes. Constructed wetlands - uses plants to treat all water.

Permenant protection of land areas by removing them from development.
- protects ecological functions and wildlife habitat
- Preservation of natural space and open character
Land Acquisition- performed by gov or nonprofit environmental entity. Protects land from development pressure or zoning
Land Trust- groups of nonprofit. use own funds or donations. usually can only protect some of the working or ecological land...not all of it.

Issues - food scarcity and lack of access to health foods
Resiliency - Feeds people without depleting resources
Urban Orchards - provide fresh food to residents and can be in a private setting
Urban Agriculture - fresh food, jobs for elderly and youth, education of food growing process
Farmer's Market - Better prices for residents and more profit for farmers. Less money spent on infrastructure to sell the produce. |
