(1) The advance planning and engineering proposal involves more than
$1,000 in United States funds; and
(2) The project application involves
more than $5,000 in U.S. funds.
Whenever possible, the sponsor must

(c) Previously obligated work. Unless
the Administrator specifically authorizes it, no advance planning and engineering proposal or project application
may include any planning, engineering,
or construction work included in a
prior agreement with the United States

Section 151.9

Runway clear zones: General.

(a) Whenever funds are allocated for
developing new runways or landing
strips, or to improve or repair existing
runways, the sponsor must own, acquire, or agree to acquire, runway clear
zones. Exceptions are considered (on
the basis of a full statement of facts by
the sponsor) upon a showing of uneconomical acquisition costs, or lack of
necessity for the acquisition.
(b) For the purpose of this part, a
runway clear zone is an area at ground
level which begins at the end of each
primary surface defined in Section 77.27(a) and
extends with the width of each approach surface defined in Section 77.27 (b) and
(c), to terminate directly below each
approach surface slope at the point, or
points, where the slope reaches a
height of 50 feet above the elevation of
the runway or 50 feet above the terrain
at the outer extremity of the clear
zone, whichever distance is shorter.
(c) For the purposes of this section,
an airport operator or owner is considered to have an adequate property in-

terest if it has an easement (or a covenant running with the land) giving it
enough control to rid the clear zone of
all obstructions (objects so far as they
project above the approach surfaces established by Section 77.27 (b) and (c) of part 77
of this chapter), and to prevent the creation of future obstructions; together
with the right of entrance and exit for
those purposes, to ensure the safe and
unrestricted passage of aircraft in and
over the area.

Section 151.11 Runway clear zones; requirements.
(a) In projects involving grants-in-aid
under the Federal-aid Airport Program, a sponsor must own, acquire, or
agree to acquire an adequate property
interest in runway clear zone areas as
prescribed in paragraph (b), (c), (d), or
(e) of this section, as applicable. Property interests that a sponsor acquires
to meet the requirements of this section are eligible for inclusion in the
Program.
(b) On new airports, the sponsor must
own, acquire, or agree to acquire adequate property interests in runway
clear zone areas (in connection with
initial land acquisition) for all eligible
runways or landing strips, without substantial deviation from standard configuration and length.
(c) On existing airports where new
runways or landing strips are developed, the sponsor must own, acquire, or
agree to acquire adequate property interests in runway clear zone areas for
each runway and landing strip to be developed or extended, to the extent that
the Administrator determines practical and feasible considering all facts
presented by the airport owner or operator, preferably without substantial
deviation from standard configuration
and length.
(d) On existing airports where improvements are made to runways or
landing strips, the sponsor must own,
acquire, or agree to acquire adequate
property interests in runway clear zone
areas for each runway or landing strip
that is to be improved to the extent
that the Administrator determines is
practical and feasible with regard to
