Airport Land Use Relationship CE 633

errata

Airport Construction Impacts • soil erosion • water and air quality (local and GHG) • noise • Materials and energy consumption • Disruption/relocation of business and homes • Airport operations

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

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 • business/convention center expansion • increased commercial/financial markets

Why? Because Location Decisions affected by: • Access to • labor, raw materials, markets • Costs • production, transportation • Quality of Life/Community Factors

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?

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

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

National Wetlands Inventory • Wetlands Mapper

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?

Lab: Land-use Planning • Land use plan is part of overall comp plan • Surrounding land use is difficult to control. • Consider airspace issues with respect to local gov’ts and planning and zoning. • 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

Noise • EPA, HUD, FAA guidelines use DNL • speech interference at 65 d. B (45 for relaxed conversation) • housing (windows open) = 15 d. B attenuation • community reaction if aircraft component > 3 -5 d. B 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 LEX
