Suburban sprawl type development would not have happened without federal government policies that supported that type of development 1. Are the suburbs what people wanted or was this type of development forced upon the public 2. Did people make a mistake in wanting suburban type development? 3. Page 38 – Lifestyle debates c. Responses to sprawl i. Growth management – page 39 ii. Smart Growth – page 39 iii. Design response 1. new Urbanism a. Set of urban design concepts that i. Emphasizes needs of people not the needs of cars http://www.newurbanism.org/pages/416429/ind ex.htm ii. Develops a strong sense of place Slide Show http://www.cnu.org/ 2. Smart Growth a. Encourage development in areas with existing infrastructure b. Push growth away from areas unsuitable for development c. Variety of government policies encourage sprawl i. Comprehensive Environmental Response, Compensation, and Liability Act (Superfund) ii. USDOT – 90% cost of new highways but much less for repair and maintenance iii. Support for central sewage lines to villages with failing septic systems. Wellsboro to Whitneyville – Mansfield to Covington iv. Regional response 1. Most metropolitan areas spread over 10s to hundreds of municipalities. 2. Little incentive for cooperation in development given property tax funding and federal grant strucutre d. Rural land use i. Rural areas experiencing inflow of population Retirees and telecommuters ii. Inexpensive land and little land use regulation is leading to larges lot, large house, scattered development iii.

How much responsibility does government have to protect development in hazardous areas iii. How much responsibility does government have to replace and repair areas damaged by predictable hazards b. Land use and public health i. Early planning was based on public health concerns communicable diseases ii. Recently shifted to ambient environment c. Land use and hydrologic systems d. Land use and agriculture i. USA surplus of agricultural lands which have little value as agricultural lands ii. Might need these lands for the future iii. What is the best way to preserve these lands iv. Maybe low density, large lot residential e. Land use and ecological resources i. Need to preserve natural resources that provide function or service to society 1. for example floodplains – aquifer recharge areas 2. Importance of biodiversity? f. Land use and energy resources g. Land use and cultural heritage h. Land use and environmental justice i. Complaints that poverty and poor ambient environment go together ii. Not clear how to redress this imbalance III. Land Use Planning a. Background data and analysis i. Most entry level jobs involve this activity b. Long range general planning i. Used to be called Comprehensive Planning c. District planning i. Transit stop planning – new town center planning d. Functional planning i. Transportation planning – open space planning e. Implementation plans i. Use to be called Capital Improvements Plan ii. Specific projects to be built to implement functional or district plan f. Community consensus IV. Emerging Trends a. Community based b. Watershed management c. Ecosystem management
