§ 151.97 

(d) Landscaping is not eligible for in-

clusion in a project. However, the es-
tablishment of turf on graded areas and 
special treatment to prevent slope ero-
sion is eligible to the extent of the eli-
gibility 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 fa-
cility 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.

§ 151.95 Fences; distance markers; 

navigational and landing aids; and 

offsite work. 

(a) Boundary or perimeter fences for 

security purposes are eligible for inclu-
sion in a project. 

(b) A blast fence is eligible for inclu-

sion in a project whenever— 

(1) It is necessary for safety at a run-

way 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 tur-

bojet-passenger gate will result in less 
separation being needed for gate posi-
tions, thereby reducing the need for 
apron expansion, and it is more eco-
nomical to build the fence than to ex-
pand the apron. 

(c) The eligibility of runway distance 

markers for inclusion in a project is de-
cided on a case-by-case basis. 

(d) The relocation of navigational 

aids is eligible for inclusion in a proj- 
ect whenever necessitated by develop-
ment 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 fol-

lowing landing aids is eligible for in-
clusion in a project: 

(1) Segmented circle. 
(2) Wind and landing direction indica-

tors. 

(3) Boundary markers. 
(f) The initial marking of runway and 

taxiway systems is eligible for inclu-

sion in a project. The remarking of ex-
isting 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(1) Present marking is obsolete under 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 equip-
ment used therein. 

However, apron marking that is not al-
lied with runway and taxiway marking 
systems, is not eligible. 

(g) The following offsite work per-

formed outside of the boundaries of an 
airport or airport site is eligible for in-
clusion in a project: 

(1) Removal of obstruction as pro-

vided in § 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 
§ 151.39(b). 

(4) Clearing, grading, and grubbing to 

allow installing of navigational aids. 

(5) Constructing and installing utili-

ties. 

(6) Lighting of obstructions.

§ 151.97 Maintenance and repair. 

(a) Maintenance work is not airport 

development as defined in the Federal 
Airport Act and is not eligible for in-
clusion in the Program. Therefore, it is 
necessary in many cases that a deter-
mination be made whether particular 
proposed development is maintenance 
or repair. For the purpose of these de-
terminations, maintenance includes 
any regular or recurring work nec-
essary to preserve existing airport fa-
cilities in good condition, any work in-
volved in cleaning or caring for exist-
ing airport facilities, and any inci-
dental or minor repair work on exist-
ing airport facilities, such as— 

(1) Mowing and fertilizing of turfed 

areas; 

(2) Trimming and replacing of land- 

scaping material; 

(3) Cleaning of drainage systems in-

cluding ditches, pipes, catch basins, 
and replacing and restoring eroded
