ENVIRONMENTAL OVERVIEW required. Construction associated with the project could generate solid waste. Waste would be handled and disposed according to federal, state, and local rules and regulations. Historical, Architectural, Archaeological, and Cultural Resources. While not required, it is recommended that the Airport complete a historic resources survey to identify the potential presence of historical, archaeological, and/or cultural resources on the land proposed for acquisition. The purchase of land would not directly affect historical, architectural, archaeological, and cultural resources, and because the land is being purchased as part of the RPZ, it would not be developed and would not cause potential effects to resources that may be present. any such resources that could be acquired as part of Airport property. The projects that would occur on existing Airport property are not anticipated to affect historical, architectural, archaeological, or cultural resources. Land Use. The acquisition of land would change the use of the land. However, it is unlikely that the acquisition of this land would change regional growth patterns, or land development patterns. The projects that would occur on Airport property would not change land use. Natural Resources and Energy Supply. The project would increase the use of energy at the Airport. However, based on the preliminary scope of each individual project, the increase in energy use would be within the service capacity of the local utility supplier. In addition, the lighting associated with each project is likely to be more energy efficient than existing lighting. Noise and Noise Compatible Land Use. The construction and operation of the terminal concourse expansion has the potential to increase the number of aircraft operating at the Airport. It is recommended that the Airport perform a preliminary noise analysis with the AEM in order to determine if there would be an increase in the aviation noise contours. If the DNL 65 dBA contour increases by 17%, the NEPA documentation would need to include a full noise analysis using AEDT. Visual Effects. The project includes construction of new buildings, which changes the viewshed of the Airport. However, these changes are consistent with airport-related development and are not expected to have visual or aesthetic effects to the surrounding area. Lighting associated with the various projects is not expected to cause a noticeable increase in light emissions from the Airport. Water Resources. The project has the potential to affect water resources, specifically wetlands, surface water, and groundwater. With regards to wetlands, the Airport would be responsible for having these wetlands officially delineated in order to determine the regulatory agency with jurisdiction over the wetlands, and the appropriate mitigation for potential effects (note that the acquisition of land for the Runway 16R RPZ would not affect wetlands or floodplains because there would be no development on that land). Assuming that the wetlands are regulated by the U.S. Army Corps of Engineers, the Airport would be responsible for obtaining a nationwide permit or individual permit, depending on the number of acres affected. With regards to surface water and groundwater, the project would increase impervious surface. The increase in impervious surface would increase the volume of stormwater runoff. Because the project would disturb over one acre of land, the Airport would be responsible for obtaining a NPDES EUGENE AIRPORT MASTER PLAN 7-22
