AIRPORT LAYOUT PLAN During the evaluation process of identifying non-standard conditions on the airfield, the location of Taxiway R was determined to be non-standard. The configuration of Taxiway R and Taxiway B3 allows for direct apron to runway access. The preferred solution to address the non-standard condition was to relocate Taxiway R to the north as shown on this sheet. Similarly, the location of Taxiway B2 was found to increase potential for runway incursion, and is proposed to eventually be relocated to the north. 6.4.9 FAR Part 77 Airspace Surface Drawing (Sheets 9-10) These scaled drawings identify obstacle identification surfaces for the full extent of all Airport development. The surfaces define the limits of recommended land use control for the height of objects ing with the runway dimensions are depicted in the ALP Drawing. A digital USGS map is used as the base map for the drawings in which each of the Federal Aviation Regulations (FAR) Part 77, Subpart C, Imaginary Surfaces (Primary, Approach, Transitional, Horizontal, and Conical) are depicted. These drawings depict the existing and future airspace configuration for the Airport. The sheets also provide numerical data for all obstructions visually depicted in plan view of the airspace surface drawing. Each obstruction is identified with a description, a top elevation, the surface the object is penetrating, the n, and a recommended disposition. Obstructions vary from vegetation to man-made objects. Some objects are defined as fixed by function, such as NAVAIDS, because of current sitting requirements and the role they play in ensuring the safe navigation of flight. Potential obstructions are identified by a negative number in An example obstruction table is shown in Table 6-1. The example shows an object penetrating the Part 77 transitional surface by 29.3 feet, with a proposed disposition to trim the tree.

Man-made penetrating obstructions are depicted in blue and identified with a top elevation. Additionally, the runway protection zone, navigational aids, and roadways are identified, and applicable data is provided. Roadways are depicted with a solid line that intersects the extended runway centerline, and dashed lines represent EUGENE AIRPORT MASTER PLAN 6-6
