  • 9. Climate Change: Human Impact on the Atmosphere• 270 Billion tons of carbon added since 19th century• Since 1750, greenhouse gases in atmosphere increased substantially: CO2 > 31% N20 > 151% CH4 > 17%• Prior to 1750, CO2 levels at 280 ppm• CO2 levels now 380 ppm; highest level in 400,000 years

  • 27. #3: Power Up Locally
  • 28. 3. Power Up Locally• Invest in renewable energy sources and jobs. – Conduct a phased rollout of local renewable energy sources – Replace natural gas and propane with electric and solar heat sources – Incentivize small-scale solar, wind, and hydro installations
  • 29. 4. Conserve and Capture• Protect our forests and farmland, sequester carbon, and convert waste into energy. – Encourage, incentivize, and mandate carbon sequestration practices – Generate energy from agricultural solid waste – Generate energy from bio gas – Improve operational efficiency – Use conservation easements to protect agriculture and forest land – Implement the Countys Integrated Waste Management Plan, and collect landfill bio gas
  • 30. WhatWhWhat will it cost to do nothing?
  • 31. AB 32: California Benefits• Public health benefits of improved air quality alone will amount to approximately $2.2 billion• Additional benefits by 2020 include: – An estimated 400 premature deaths statewide will be avoided – Almost 11,000 incidences of asthma and lower respiratory symptoms will be avoided – 67,000 work loss days will be avoided – Reduced risks of coronary heart disease, diabetes, hypertension and obesity

  • 42. New Urbanism- City PlanningGiving Physical Shape to CommunityOne urban design movement calledNew Urbanism is affecting the wayour cities and towns are built.
  • 43. What’s Old in New UrbanismSince America was founded, many of ourbest-loved towns and cities have beencarefully planned.
  • 44. Giving Physical Shape to CommunityNew urbanist developments arewalkable neighborhoods, ratherthan large, single-use places withstreets hostile to pedestrians.
  • 45. Giving Physical Shape to CommunityNew Urbanism provides a range ofhousing choices, from apartmentsover storefronts to single-familyhomes with yards.
  • 46. The Disposable CityFor many years older American citieswere neglected and deteriorating. Newhome buyers were almost exclusivelyinterested in living on the urban fringe.
  • 47. Response to a ProblemSince World War II, cities have been spreading ever-outward. Strip malls,parking lots, highways, and housing tracts have sprawled over the landscape.
  • 48. Cities Getting With the ProgramNevertheless, many young childless households and older empty nesters appreciate theadvantages of urban living. Up until recently when the housing market tanked - urbanreinvestment was paying off – and some older cities were among America’s hottest realestate markets.
  • 49. Where it’s neededNew Urbanism can be small projects on individual blocks, like the block on8th and Pearl in Boulder, Colorado.
  • 50. Where it’s neededIt can also apply to redeveloped neighborhoods like Park DuValle in Louisville, Kentucky.
  • 51. Other SuccessesThe U.S. Department of Housingand Urban Development has takenNew Urbanism to heart with its HOPEVI program. HOPE VI replaces aging,alienating housing projects withtownhouses, single-family homes,and apartments on walkable,comfortable street grids.
  • 52. Where it may or may not be needed?New Urbanism includes greenfield projects, also called traditional neighborhooddevelopments (TNDs). Marylands Kentlands and Lakelands are among the best-known.
  • 53. Early EffortsThe first new urbanist town to get built from theground up was Seaside, on the Florida coast.
  • 54. Early EffortsBetween 1985 and 1993, several morelarge-scale projects were undertaken inAmerica’s fast-growing suburbs.Kentlands and Laguna West were two ofthe best-known and most ambitious efforts. Laguna West, CA Kentlands, MD
  • 55. Where it’s neededNew Urbanists also take part in regional planning. In New Jersey, a statewideplan has focused public investment into existing centers, and a statewide designguideline is helping keep the state’s small towns vibrant.
  • 56. The RegionThe region is the overall context for allplanning. That means planning must oftencross traditional jurisdictional lines inorder to create a healthy region.
  • 57. The RegionTowns and cities within aregion should have clearboundaries, contributing toa sense of place. The landbetween towns should bepreserved as open space—wilderness or farm-land.These edges are as importantas the centers to the successof New Urbanism.
  • 58. The RegionWilderness, farmland, villages, town edges, town centers, city neighborhoods, and citycenters each have their own building densities, street sizes, and appropriate mixtures ofretail, residential, and other functions.
  • 59. The NeighborhoodThe optimal size of a neighborhood isa quarter-mile from center to edge.For most people, a quarter mile is afive-minute walk. For aneighborhood to feel walkable, manydaily needs should be supplied withinthis five-minute walk. That includesnot only homes, but stores,workplaces, schools, houses ofworship, and recreational areas.
  • 60. The NeighborhoodPeople within a quarter-mile radius will walk to amajor transit stop. Those who live further from a transitnode are less likely to bother with the train or bus.
  • 61. The Block, Street, and BuildingNew urbanist streets usebuildings to provide a con-sistent and understandableedge and streets are safe,comfortable, interestingplaces for people to walkand meet.Buildings open ontosidewalks, rather thanparking lots. Windows anddoors facing the sidewalkmake streets safer, and moreinteresting, for everyone.
  • 62. Progress in the SuburbsIn new suburban developments, new urbanistsare including an ever-wider range ofarchitectural styles. While many new urbanistdevelopments have been built with colonial-stylearchitecture, recent projects includeneighborhoods of contemporary homes andadobe.
  • 63. Other SuccessesMall redevelopment: Some mallsbuilt in the 1960s, 70s, and even 80sare underutilized or already failing incities and older suburbs. Some arebeing converted into realneighborhoods.

  • 73. GREENING Transportation• Prioritize funding for projects that reduce fossil-fuel use and single-occupancy auto trips• Provide incentives for using public transit, carpools, car sharing, bicycles, walking, etc• Reduce parking requirements for projects located near transit or thru trip reduction programs
  • 74. The Redevelopment Plan calls for:• nearly 3,400 new homes (35% of which will be affordable)• 1.2 million square feet of new office, hotel, and commercial space and 60,000 square feet of retail• Buildings to be spaced apart to provide sunlight to proposed new plazas, parks, and widened sidewalks
