Section 151.95 14 CFR Ch. I (1-1-19 Edition) (d) Landscaping is not eligible for inclusion in a project. However, the establishment of turf on graded areas and special treatment to prevent slope erosion is eligible to the extent of the eligibility of the facilities or areas served, preserved, or protected by the turf or treatment. In the case of turfing or treatment for an area or facility that is partly eligible and partly ineligible, the eligibility of the turfing or treatment is established on a pro rata basis. (e) The construction of sidewalks is not eligible for inclusion in a project. [Doc. No. 1329, 27 FR 12357, Dec. 13, 1962, as amended by Amdt. 151-17, 31 FR 16525, Dec. 28, 1966; Amdt. 151-26, 33 FR 18434, Dec. 12, 1968] Section 151.95 Fences; distance markers; navigational and landing aids; and offsite work. (a) Boundary or perimeter fences for security purposes are eligible for inclusion in a project. (b) A blast fence is eligible for inclusion in a project whenever - (1) It is necessary for safety at a runway end or a holding area near the end of a runway and its installation would be more economical than the acquiring of additional property interests; or (2) Its installation for safety at a turbojet-passenger gate will result in less separation being needed for gate positions, thereby reducing the need for apron expansion, and it is more economical to build the fence than to expand the apron. (c) The eligibility of runway distance markers for inclusion in a project is decided on a case-by-case basis. (d) The relocation of navigational aids is eligible for inclusion in a project whenever necessitated by development on the airport under a Program project and the sponsor is responsible under FAA Order OA 6030.1 (Agency Order 53). (e) The installation of any of the following landing aids is eligible for inclusion in a project: (1) Segmented circle. (2) Wind and landing direction indicators. (3) Boundary markers. (f) The initial marking of runway and taxiway systems is eligible for inclu- sion in a project. The remarking of existing runways or taxiways is eligible if - (1) Present marking is obsolete under current FAA standards; or (2) Present marking is obliterated by construction, alteration or repair work included in a FAAP project or by the required routing of construction equipment used therein. However, apron marking that is not allied with runway and taxiway marking systems, is not eligible. (g) The following offsite work performed outside of the boundaries of an airport or airport site is eligible for inclusion in a project: (1) Removal of obstruction as provided in Section 151.91. (2) Outfall drainage ditches, and the correction of any damage resulting from their construction. (3) Relocating of roads and utilities that are airport hazards as defined in Section 151.39(b). (4) Clearing, grading, and grubbing to allow installing of navigational aids. (5) Constructing and installing utilities. (6) Lighting of obstructions. [Doc. No. 1329, 27 FR 12359, Dec. 13, 1962, as amended by Amdt. 151-8, 30 FR 8040, June 23, 1965; Amdt. 151-17, 31 FR 16525, Dec. 28, 1966] Section 151.97 Maintenance and repair. (a) Maintenance work is not airport development as defined in the Federal Airport Act and is not eligible for inclusion in the Program. Therefore, it is necessary in many cases that a determination be made whether particular proposed development is maintenance or repair. For the purpose of these determinations, maintenance includes any regular or recurring work necessary to preserve existing airport facilities in good condition, any work involved in cleaning or caring for existing airport facilities, and any incidental or minor repair work on existing airport facilities, such as - (1) Mowing and fertilizing of turfed areas; (2) Trimming and replacing of landscaping material; (3) Cleaning of drainage systems including ditches, pipes, catch basins, and replacing and restoring eroded 702 VerDate Sep<11>2014 08:20 May 17, 2019 Jkt 247048 PO 00000 Frm 00712 Fmt 8010 Sfmt 8010 Y:\SGML\247048.XXX 247048
