  1. Airport Impact on Land Use Important: view in slideshow mode

  2. Airport Construction Impacts • soil erosion • water and air quality • noise • materials used • disruption/relocation of business and homes • operations • other construction

  3. Construction Impact Mitigation • Review environmentally sensitive areas • identify amount of cut and fill • identify methods to prevent erosion • materials handling procedures air/water quality • optimize routing/timing to minimize noise • disruption plan with local business

  4. Airport’s Impact on Land Development • The following may require land for development: • Plant relocation/construction • expansion of existing plants • increased tourism/retail/recreation facilities • expansion of ag markets (not corn!) • business/convention center expansion • increased commercial/financial markets

  5. Why? … because Location Decisions affected by: • Access to • labor, raw materials, markets • Costs • production, transportation • Quality of Life/Community Factors • (holds for Airports as well as other forms of transportation)

  6. Cultural Resource Impact • Parks and recreation areas • historical and archeological sites • natural/scenic beauty • for each ... • does airport cause physical changes? • does airport conform (fit in)? • does airport disrupt access, ambience? • What is impact of induced development?

  7. Ecological Factors Lists of endangered species available Must Check: • Vegetation requirements • food chain • habitats • migration, spawning grounds • species tolerance to pollution • see website

  8. Wetland Impact Potentially harmful activities: • Clearing • topography changes • pest control • vehicle washing • deicing, servicing • fueling

  9. National Wetlands Inventory • http://www.nwi.fws.gov/ • Go to National Wetlands Inventory (right click if not in slide show mode) • use http://ecos.fws.gov/nwi_mapplet/ to show interactive map (try it for Des Moines A/P -93W39’ 41N32’!) • check out the terraserver view and acreage summaries under “utilities” at bottom

  10. Environmental Impact Summary • Original impetus for considering environment was legislation ... • First, costs of planning increased • but, better understanding of short and long term impacts on society • therefore, more efficient designs • Q: lower long term costs to society?

  11. Lab: Land-use Planning • Land use plan is part of overall comp plan • Incompatible land use (noise) is biggest problem, therefore, must • forecast noise levels • overlay noise “contours” on land use map • estimate compatibility • establish zoning for underdeveloped land

  12. A little more on Noise • EPA, HUD, FAA guidelines use DNL • speech interference at 65dB (45 for relaxed conversation) • housing (windows open) = 15dB attenuation • community reaction if aircraft component > 3-5 dB above ambient • please see table 15-2 for land-use compatibility • noise can be measured or modeled (we will use INM to model it for DSM
