ENVIRONMENTAL OVERVIEW The Airport is zoned as a light industrial land use, and is developed in a manner that is consistent with this zoning. Structures at the Airport include, but are not limited to, the terminal building, FBO, hangars, and maintenance buildings. The majority of the land adjacent to the Airport property is agricultural land, which allows for a direct view to the Airport from the nearby residential areas. Water Resources The following sections provide a brief description of existing water resources at the Airport. FAA Order 1050.1F has grouped the following resource categories under Water Resources; wetlands, floodplains, surface waters, groundwater, and wild and scenic rivers. 7.2.14.1 Wetlands Wetlands were identified during the site survey and mapped for future development considerations (see Figure 1-20), but no jurisdiction determinations were made for the identified wetlands. 7.2.14.2 Floodplains According to current Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps for the 11 Airport area, there are floodplains within the Airport property. The floodplains are located in the western, northeastern, and southern portions of the Airport property boundary (see Figure 1-21). 7.2.14.3 Surface Waters Various surface waters have been identified on Airport property(see Figure 1-22): Amazon Creek/Clear Lake Stream, two unnamed streams, and three unnamed water bodies (i.e., pond/lake). 7.2.14.4 Groundwater 12 The Airport is within two hydrologic units: Amazon Creek Watershed and Flat Creek Watershed. The northeastern portion of the Airport is within the Flat Creek watershed (HUC 12 ID: 170900030603). The Eugene Water and Electric Board (EWEB), which receives its water supply from the McKenzie River, provides water services to the Airport. 7.2.14.5 Wild and Scenic Rivers The closest wild and scenic river, the North Fork Middle Fork Willamette River, is over 40 miles southeast of the Airport. ENVIRONMENTAL ANALYSIS OF THEAIRPORT DEVELOPMENTPLAN For purposes of this Master Plan Update, the level of analysis outlined in this section is to advise the Airport of potential environmental impacts associated with the Implementation Plan.
