Sec. 1.170A-14  Qualified conservation contributions.

    (a) Qualified conservation contributions. A deduction under section 
170 is generally not allowed for a charitable contribution of any 
interest in property that consists of less than the donor's entire 
interest in the property other than certain transfers in trust (see 
Sec. 1.170A-6 relating to charitable contributions in trust and Sec. 
1.170A-7 relating to contributions not in trust of partial interests in 
property). However,

[[Page 150]]

a deduction may be allowed under section 170(f)(3)(B)(iii) for the value 
of a qualified conservation contribution if the requirements of this 
section are met. A qualified conservation contribution is the 
contribution of a qualified real property interest to a qualified 
organization exclusively for conservation purposes. To be eligible for a 
deduction under this section, the conservation purpose must be protected 
in perpetuity.
    (b) Qualified real property interest--(1) Entire interest of donor 
other than qualified mineral interest. (i) The entire interest of the 
donor other than a qualified mineral interest is a qualified real 
property interest. A qualified mineral interest is the donor's interest 
in subsurface oil, gas, or other minerals and the right of access to 
such minerals.
    (ii) A real property interest shall not be treated as an entire 
interest other than a qualified mineral interest by reason of section 
170(h)(2)(A) and this paragraph (b)(1) if the property in which the 
donor's interest exists was divided prior to the contribution in order 
to enable the donor to retain control of more than a qualified mineral 
interest or to reduce the real property interest donated. See Treasury 
regulations Sec. 1.170A-7(a)(2)(i). An entire interest in real property 
may consist of an undivided interest in the property. But see section 
170(h)(5)(A) and the regulations thereunder (relating to the requirement 
that the conservation purpose which is the subject of the donation must 
be protected in perpetuity). Minor interests, such as rights-of-way, 
that will not interfere with the conservation purposes of the donation, 
may be transferred prior to the conservation contribution without 
affecting the treatment of a property interest as a qualified real 
property interest under this paragraph (b)(1).
    (2) Perpetual conservation restriction. A ``perpetual conservation 
restriction'' is a qualified real property interest. A ``perpetual 
conservation restriction'' is a restriction granted in perpetuity on the 
use which may be made of real property--including, an easement or other 
interest in real property that under state law has attributes similar to 
an easement (e.g., a restrictive covenant or equitable servitude). For 
purposes of this section, the terms easement, conservation restriction, 
and perpetual conservation restriction have the same meaning. The 
definition of perpetual conservation restriction under this paragraph 
(b)(2) is not intended to preclude the deductibility of a donation of 
affirmative rights to use a land or water area under Sec. 1.170A-
13(d)(2). Any rights reserved by the donor in the donation of a 
perpetual conservation restriction must conform to the requirements of 
this section. See e.g., paragraph (d)(4)(ii), (d)(5)(i), (e)(3), and 
(g)(4) of this section.
    (c) Qualified organization--(1) Eligible donee. To be considered an 
eligible donee under this section, an organization must be a qualified 
organization, have a commitment to protect the conservation purposes of 
the donation, and have the resources to enforce the restrictions. A 
conservation group organized or operated primarily or substantially for 
one of the conservation purposes specified in section 170(h)(4)(A) will 
be considered to have the commitment required by the preceding sentence. 
A qualified organization need not set aside funds to enforce the 
restrictions that are the subject of the contribution. For purposes of 
this section, the term qualified organization means:
    (i) A governmental unit described in section 170(b)(1)(A)(v);
    (ii) An organization described in section 170(b)(1)(A)(vi);
    (iii) A charitable organization described in section 501(c)(3) that 
meets the public support test of section 509(a)(2);
    (iv) A charitable organization described in section 501(c)(3) that 
meets the requirements of section 509(a)(3) and is controlled by an 
organization described in paragraphs (c)(1) (i), (ii), or (iii) of this 
section.
    (2) Transfers by donee. A deduction shall be allowed for a 
contribution under this section only if in the instrument of conveyance 
the donor prohibits the donee from subsequently transferring the 
easement (or, in the case of a remainder interest or the reservation of 
a qualified mineral interest, the property), whether or not for 
consideration, unless the donee organization, as a condition of the 
subsequent

[[Page 151]]

transfer, requires that the conservation purposes which the contribution 
was originally intended to advance continue to be carried out. Moreover, 
subsequent transfers must be restricted to organizations qualifying, at 
the time of the subsequent transfer, as an eligible donee under 
paragraph (c)(1) of this section. When a later unexpected change in the 
conditions surrounding the property that is the subject of a donation 
under paragraph (b)(1), (2), or (3) of this section makes impossible or 
impractical the continued use of the property for conservation purposes, 
the requirement of this paragraph will be met if the property is sold or 
exchanged and any proceeds are used by the donee organization in a 
manner consistent with the conservation purposes of the original 
contribution. In the case of a donation under paragraph (b)(3) of this 
section to which the preceding sentence applies, see also paragraph 
(g)(5)(ii) of this section.
    (d) Conservation purposes--(1) In general. For purposes of section 
170(h) and this section, the term conservation purposes means--
    (i) The preservation of land areas for outdoor recreation by, or the 
education of, the general public, within the meaning of paragraph (d)(2) 
of this section,
    (ii) The protection of a relatively natural habitat of fish, 
wildlife, or plants, or similar ecosystem, within the meaning of 
paragraph (d)(3) of this section,
    (iii) The preservation of certain open space (including farmland and 
forest land) within the meaning of paragraph (d)(4) of this section, or
    (iv) The preservation of a historically important land area or a 
certified historic structure, within the meaning of paragraph (d)(5) of 
this section.
    (2) Recreation or education--(i) In general. The donation of a 
qualified real property interest to preserve land areas for the outdoor 
recreation of the general public or for the education of the general 
public will meet the conservation purposes test of this section. Thus, 
conservation purposes would include, for example, the preservation of a 
water area for the use of the public for boating or fishing, or a nature 
or hiking trail for the use of the public.
    (ii) Access. The preservation of land areas for recreation or 
education will not meet the test of this section unless the recreation 
or education is for the substantial and regular use of the general 
public.
    (3) Protection of environmental system--(i) In general. The donation 
of a qualified real property interest to protect a significant 
relatively natural habitat in which a fish, wildlife, or plant 
community, or similar ecosystem normally lives will meet the 
conservation purposes test of this section. The fact that the habitat or 
environment has been altered to some extent by human activity will not 
result in a deduction being denied under this section if the fish, 
wildlife, or plants continue to exist there in a relatively natural 
state. For example, the preservation of a lake formed by a man-made dam 
or a salt pond formed by a man-made dike would meet the conservation 
purposes test if the lake or pond were a nature feeding area for a 
wildlife community that included rare, endangered, or threatened native 
species.
    (ii) Significant habitat or ecosystem. Significant habitats and 
ecosystems include, but are not limited to, habitats for rare, 
endangered, or threatened species of animal, fish, or plants; natural 
areas that represent high quality examples of a terrestrial community or 
aquatic community, such as islands that are undeveloped or not intensely 
developed where the coastal ecosystem is relatively intact; and natural 
areas which are included in, or which contribute to, the ecological 
viability of a local, state, or national park, nature preserve, wildlife 
refuge, wilderness area, or other similar conservation area.
    (iii) Access. Limitations on public access to property that is the 
subject of a donation under this paragraph (d)(3) shall not render the 
donation nondeductible. For example, a restriction on all public access 
to the habitat of a threatened native animal species protected by a 
donation under this paragraph (d)(3) would not cause the donation to be 
nondeductible.
    (4) Preservation of open space--(i) In general. The donation of a 
qualified real property interest to preserve open space (including 
farmland and forest

[[Page 152]]

land) will meet the conservation purposes test of this section if such 
preservation is--
    (A) Pursuant to a clearly delineated Federal, state, or local 
governmental conservation policy and will yield a significant public 
benefit, or
    (B) For the scenic enjoyment of the general public and will yield a 
significant public benefit.

An open space easement donated on or after December 18, 1980, must meet 
the requirements of section 170(h) in order to be deductible.
    (ii) Scenic enjoyment--(A) Factors. A contribution made for the 
preservation of open space may be for the scenic enjoyment of the 
general public. Preservation of land may be for the scenic enjoyment of 
the general public if development of the property would impair the 
scenic character of the local rural or urban landscape or would 
interfere with a scenic panorama that can be enjoyed from a park, nature 
preserve, road, waterbody, trail, or historic structure or land area, 
and such area or transportation way is open to, or utilized by, the 
public. ``Scenic enjoyment'' will be evaluated by considering all 
pertinent facts and circumstances germane to the contribution. Regional 
variations in topography, geology, biology, and cultural and economic 
conditions require flexibility in the application of this test, but do 
not lessen the burden on the taxpayer to demonstrate the scenic 
characteristics of a donation under this paragraph. The application of a 
particular objective factor to help define a view as scenic in one 
setting may in fact be entirely inappropriate in another setting. Among 
the factors to be considered are:
    (1) The compatibility of the land use with other land in the 
vicinity;
    (2) The degree of contrast and variety provided by the visual scene;
    (3) The openness of the land (which would be a more significant 
factor in an urban or densely populated setting or in a heavily wooded 
area);
    (4) Relief from urban closeness;
    (5) The harmonious variety of shapes and textures;
    (6) The degree to which the land use maintains the scale and 
character of the urban landscape to preserve open space, visual 
enjoyment, and sunlight for the surrounding area;
    (7) The consistency of the proposed scenic view with a methodical 
state scenic identification program, such as a state landscape 
inventory; and
    (8) The consistency of the proposed scenic view with a regional or 
local landscape inventory made pursuant to a sufficiently rigorous 
review process, especially if the donation is endorsed by an appropriate 
state or local governmental agency.
    (B) Access. To satisfy the requirement of scenic enjoyment by the 
general public, visual (rather than physical) access to or across the 
property by the general public is sufficient. Under the terms of an open 
space easement on scenic property, the entire property need not be 
visible to the public for a donation to qualify under this section, 
although the public benefit from the donation may be insufficient to 
qualify for a deduction if only a small portion of the property is 
visible to the public.
    (iii) Governmental conservation policy--(A) In general. The 
requirement that the preservation of open space be pursuant to a clearly 
delineated Federal, state, or local governmental policy is intended to 
protect the types of property identified by representatives of the 
general public as worthy of preservation or conservation. A general 
declaration of conservation goals by a single official or legislative 
body is not sufficient. However, a governmental conservation policy need 
not be a certification program that identifies particular lots or small 
parcels of individually owned property. This requirement will be met by 
donations that further a specific, identified conservation project, such 
as the preservation of land within a state or local landmark district 
that is locally recognized as being significant to that district; the 
preservation of a wild or scenic river, the preservation of farmland 
pursuant to a state program for flood prevention and control; or the 
protection of the scenic, ecological, or historic character of land that 
is contiguous to, or an integral part of, the surroundings of existing 
recreation or conservation sites. For example, the donation of a 
perpetual conservation restriction to a qualified organization pursuant 
to a

[[Page 153]]

formal resolution or certification by a local governmental agency 
established under state law specifically identifying the subject 
property as worthy of protection for conservation purposes will meet the 
requirement of this paragraph. A program need not be funded to satisfy 
this requirement, but the program must involve a significant commitment 
by the government with respect to the conservation project. For example, 
a governmental program according preferential tax assessment or 
preferential zoning for certain property deemed worthy of protection for 
conservation purposes would constitute a significant commitment by the 
government.
    (B) Effect of acceptance by governmental agency. Acceptance of an 
easement by an agency of the Federal Government or by an agency of a 
state or local government (or by a commission, authority, or similar 
body duly constituted by the state or local government and acting on 
behalf of the state or local government) tends to establish the 
requisite clearly delineated governmental policy, although such 
acceptance, without more, is not sufficient. The more rigorous the 
review process by the governmental agency, the more the acceptance of 
the easement tends to establish the requisite clearly delineated 
governmental policy. For example, in a state where the legislature has 
established an Environmental Trust to accept gifts to the state which 
meet certain conservation purposes and to submit the gifts to a review 
that requires the approval of the state's highest officials, acceptance 
of a gift by the Trust tends to establish the requisite clearly 
delineated governmental policy. However, if the Trust merely accepts 
such gifts without a review process, the requisite clearly delineated 
governmental policy is not established.
    (C) Access. A limitation on public access to property subject to a 
donation under this paragraph (d)(4)(iii) shall not render the deduction 
nondeductible unless the conservation purpose of the donation would be 
undermined or frustrated without public access. For example, a donation 
pursuant to a governmental policy to protect the scenic character of 
land near a river requires visual access to the same extent as would a 
donation under paragraph (d)(4)(ii) of this section.
    (iv) Significant public benefit--(A) Factors. All contributions made 
for the preservation of open space must yield a significant public 
benefit. Public benefit will be evaluated by considering all pertinent 
facts and circumstances germane to the contribution. Factors germane to 
the evaluation of public benefit from one contribution may be irrelevant 
in determining public benefit from another contribution. No single 
factor will necessarily be determinative. Among the factors to be 
considered are:
    (1) The uniqueness of the property to the area;
    (2) The intensity of land development in the vicinity of the 
property (both existing development and foreseeable trends of 
development);
    (3) The consistency of the proposed open space use with public 
programs (whether Federal, state or local) for conservation in the 
region, including programs for outdoor recreation, irrigation or water 
supply protection, water quality maintenance or enhancement, flood 
prevention and control, erosion control, shoreline protection, and 
protection of land areas included in, or related to, a government 
approved master plan or land management area;
    (4) The consistency of the proposed open space use with existing 
private conservation programs in the area, as evidenced by other land, 
protected by easement or fee ownership by organizations referred to in 
Sec. 1.170A-14(c)(1), in close proximity to the property;
    (5) The likelihood that development of the property would lead to or 
contribute to degradation of the scenic, natural, or historic character 
of the area;
    (6) The opportunity for the general public to use the property or to 
appreciate its scenic values;
    (7) The importance of the property in preserving a local or regional 
landscape or resource that attracts tourism or commerce to the area;
    (8) The likelihood that the donee will acquire equally desirable and 
valuable substitute property or property rights;

[[Page 154]]

    (9) The cost to the donee of enforcing the terms of the conservation 
restriction;
    (10) The population density in the area of the property; and
    (11) The consistency of the proposed open space use with a 
legislatively mandated program identifying particular parcels of land 
for future protection.
    (B) Illustrations. The preservation of an ordinary tract of land 
would not in and of itself yield a significant public benefit, but the 
preservation of ordinary land areas in conjunction with other factors 
that demonstrate significant public benefit or the preservation of a 
unique land area for public employment would yield a significant public 
benefit. For example, the preservation of a vacant downtown lot would 
not by itself yield a significant public benefit, but the preservation 
of the downtown lot as a public garden would, absent countervailing 
factors, yield a significant public benefit. The following are other 
examples of contributions which would, absent countervailing factors, 
yield a significant public benefit: The preservation of farmland 
pursuant to a state program for flood prevention and control; the 
preservation of a unique natural land formation for the enjoyment of the 
general public; the preservation of woodland along a public highway 
pursuant to a government program to preserve the appearance of the area 
so as to maintain the scenic view from the highway; and the preservation 
of a stretch of undeveloped property located between a public highway 
and the ocean in order to maintain the scenic ocean view from the 
highway.
    (v) Limitation. A deduction will not be allowed for the preservation 
of open space under section 170(h)(4)(A)(iii), if the terms of the 
easement permit a degree of intrusion or future development that would 
interfere with the essential scenic quality of the land or with the 
governmental conservation policy that is being furthered by the 
donation. See Sec. 1.170A-14(e)(2) for rules relating to inconsistent 
use.
    (vi) Relationship of requirements--(A) Clearly delineated 
governmental policy and significant public benefit. Although the 
requirements of ``clearly delineated governmental policy'' and 
``significant public benefit'' must be met independently, for purposes 
of this section the two requirements may also be related. The more 
specific the governmental policy with respect to the particular site to 
be protected, the more likely the governmental decision, by itself, will 
tend to establish the significant public benefit associated with the 
donation. For example, while a statute in State X permitting 
preferential assessment for farmland is, by definition, governmental 
policy, it is distinguishable from a state statute, accompanied by 
appropriations, naming the X River as a valuable resource and 
articulating the legislative policy that the X River and the relatively 
natural quality of its surrounding be protected. On these facts, an open 
space easement on farmland in State X would have to demonstrate 
additional factors to establish ``significant public benefit.'' The 
specificity of the legislative mandate to protect the X River, however, 
would by itself tend to establish the significant public benefit 
associated with an open space easement on land fronting the X River.
    (B) Scenic enjoyment and significant public benefit. With respect to 
the relationship between the requirements of ``scenic enjoyment'' and 
``significant public benefit,'' since the degrees of scenic enjoyment 
offered by a variety of open space easements are subjective and not as 
easily delineated as are increasingly specific levels of governmental 
policy, the significant public benefit of preserving a scenic view must 
be independently established in all cases.
    (C) Donations may satisfy more than one test. In some cases, open 
space easements may be both for scenic enjoyment and pursuant to a 
clearly delineated governmental policy. For example, the preservation of 
a particular scenic view identified as part of a scenic landscape 
inventory by a rigorous governmental review process will meet the tests 
of both paragraphs (d)(4)(i)(A) and (d)(4)(i)(B) of this section.
    (5) Historic preservation--(i) In general. The donation of a 
qualified real property interest to preserve an historically important 
land area or a certified

[[Page 155]]

historic structure will meet the conservation purposes test of this 
section. When restrictions to preserve a building or land area within a 
registered historic district permit future development on the site, a 
deduction will be allowed under this section only if the terms of the 
restrictions require that such development conform with appropriate 
local, state, or Federal standards for construction or rehabilitation 
within the district. See also, Sec. 1.170A-14(h)(3)(ii).
    (ii) Historically important land area. The term historically 
important land area includes:
    (A) An independently significant land area including any related 
historic resources (for example, an archaeological site or a Civil War 
battlefield with related monuments, bridges, cannons, or houses) that 
meets the National Register Criteria for Evaluation in 36 CFR 60.4 (Pub. 
L. 89-665, 80 Stat. 915);
    (B) Any land area within a registered historic district including 
any buildings on the land area that can reasonably be considered as 
contributing to the significance of the district; and
    (C) Any land area (including related historic resources) adjacent to 
a property listed individually in the National Register of Historic 
Places (but not within a registered historic district) in a case where 
the physical or environmental features of the land area contribute to 
the historic or cultural integrity of the property.
    (iii) Certified historic structure. The term certified historic 
structure, for purposes of this section, means any building, structure 
or land area which is--
    (A) Listed in the National Register, or
    (B) Located in a registered historic district (as defined in section 
48(g)(3)(B)) and is certified by the Secretary of the Interior (pursuant 
to 36 CFR 67.4) to the Secretary of the Treasury as being of historic 
significance to the district.

A structure for purposes of this section means any structure, whether or 
not it is depreciable. Accordingly easements on private residences may 
qualify under this section. In addition, a structure would be considered 
to be a certified historic structure if it were certified either at the 
time the transfer was made or at the due date (including extensions) for 
filing the donor's return for the taxable year in which the contribution 
was made.
    (iv) Access. (A) In order for a conservation contribution described 
in section 170(h)(4)(A)(iv) and this paragraph (d)(5) to be deductible, 
some visual public access to the donated property is required. In the 
case of an historically important land area, the entire property need 
not be visible to the public for a donation to qualify under this 
section. However, the public benefit from the donation may be 
insufficient to qualify for a deduction if only a small portion of the 
property is so visible. Where the historic land area or certified 
historic structure which is the subject of the donation is not visible 
from a public way (e.g., the structure is hidden from view by a wall or 
shrubbery, the structure is too far from the public way, or interior 
characteristics and features of the structure are the subject of the 
easement), the terms of the easement must be such that the general 
public is given the opportunity on a regular basis to view the 
characteristics and features of the property which are preserved by the 
easement to the extent consistent with the nature and condition of the 
property.
    (B) Factors to be considered in determining the type and amount of 
public access required under paragraph (d)(5)(iv)(A) of this section 
include the historical significance of the donated property, the nature 
of the features that are the subject of the easement, the remoteness or 
accessibility of the site of the donated property, the possibility of 
physical hazards to the public visiting the property (for example, an 
unoccupied structure in a dilapidated condition), the extent to which 
public access would be an unreasonable intrusion on any privacy 
interests of individuals living on the property, the degree to which 
public access would impair the preservation interests which are the 
subject of the donation, and the availability of opportunities for the 
public to view the property by means other than visits to the site.
    (C) The amount of access afforded the public by the donation of an 
easement shall be determined with reference to the amount of access 
permitted by the

[[Page 156]]

terms of the easement which are established by the donor, rather than 
the amount of access actually provided by the donee organization. 
However, if the donor is aware of any facts indicating that the amount 
of access that the donee organization will provide is significantly less 
than the amount of access permitted under the terms of the easement, 
then the amount of access afforded the public shall be determined with 
reference to this lesser amount.
    (v) Examples. The provisions of paragraph (d)(5)(iv) of this section 
may be illustrated by the following examples:

    Example 1. A and his family live in a house in a certified historic 
district in the State of X. The entire house, including its interior, 
has architectural features representing classic Victorian period 
architecture. A donates an exterior and interior easement on the 
property to a qualified organization but continues to live in the house 
with his family. A's house is surrounded by a high stone wall which 
obscures the public's view of it from the street. Pursuant to the terms 
of the easement, the house may be opened to the public from 10:00 a.m. 
to 4:00 p.m. on one Sunday in May and one Sunday in November each year 
for house and garden tours. These tours are to be under the supervision 
of the donee and open to members of the general public upon payment of a 
small fee. In addition, under the terms of the easement, the donee 
organization is given the right to photograph the interior and exterior 
of the house and distribute such photographs to magazines, newsletters, 
or other publicly available publications. The terms of the easement also 
permit persons affiliated with educational organizations, professional 
architectural associations, and historical societies to make an 
appointment through the donee organization to study the property. The 
donor is not aware of any facts indicating that the public access to be 
provided by the donee organization will be significantly less than that 
permitted by the terms of the easement. The 2 opportunities for public 
visits per year, when combined with the ability of the general public to 
view the architectural characteristics and features that are the subject 
of the easement through photographs, the opportunity for scholarly study 
of the property, and the fact that the house is used as an occupied 
residence, will enable the donation to satisfy the requirement of public 
access.
    Example 2. B owns an unoccupied farmhouse built in the 1840's and 
located on a property that is adjacent to a Civil War battlefield. 
During the Civil War the farmhouse was used as quarters for Union 
troops. The battlefield is visited year round by the general public. The 
condition of the farmhouse is such that the safety of visitors will not 
be jeopardized and opening it to the public will not result in 
significant deterioration. The farmhouse is not visible from the 
battlefield or any public way. It is accessible only by way of a private 
road owned by B. B donates a conservation easement on the farmhouse to a 
qualified organization. The terms of the easement provide that the donee 
organization may open the property (via B's road) to the general public 
on four weekends each year from 8:30 a.m. to 4:00 p.m. The donation does 
not meet the public access requirement because the farmhouse is safe, 
unoccupied, and easily accessible to the general public who have come to 
the site to visit Civil War historic land areas (and related resources), 
but will only be open to the public on four weekends each year. However, 
the donation would meet the public access requirement if the terms of 
the easement permitted the donee organization to open the property to 
the public every other weekend during the year and the donor is not 
aware of any facts indicating that the donee organization will provide 
significantly less access than that permitted.

    (e) Exclusively for conservation purposes--(1) In general. To meet 
the requirements of this section, a donation must be exclusively for 
conservation purposes. See paragraphs (c)(1) and (g)(1) through 
(g)(6)(ii) of this section. A deduction will not be denied under this 
section when incidental benefit inures to the donor merely as a result 
of conservation restrictions limiting the uses to which the donor's 
property may be put.
    (2) Inconsistent use. Except as provided in paragraph (e)(4) of this 
section, a deduction will not be allowed if the contribution would 
accomplish one of the enumerated conservation purposes but would permit 
destruction of other significant conservation interests. For example, 
the preservation of farmland pursuant to a State program for flood 
prevention and control would not qualify under paragraph (d)(4) of this 
section if under the terms of the contribution a significant naturally 
occurring ecosystem could be injured or destroyed by the use of 
pesticides in the operation of the farm. However, this requirement is 
not intended to prohibit uses of the property, such as selective timber 
harvesting or selective farming if, under the circumstances, those uses 
do not impair significant conservation interests.

[[Page 157]]

    (3) Inconsistent use permitted. A use that is destructive of 
conservation interests will be permitted only if such use is necessary 
for the protection of the conservation interests that are the subject of 
the contribution. For example, a deduction for the donation of an 
easement to preserve an archaeological site that is listed on the 
National Register of Historic Places will not be disallowed if site 
excavation consistent with sound archaeological practices may impair a 
scenic view of which the land is a part. A donor may continue a pre-
existing use of the property that does not conflict with the 
conservation purposes of the gift.
    (f) Examples. The provisions of this section relating to 
conservation purposes may be illustrated by the following examples.

    Example 1. State S contains many large tract forests that are 
desirable recreation and scenic areas for the general public. The 
forests' scenic values attract millions of people to the State. However, 
due to the increasing intensity of land development in State S, the 
continued existence of forestland parcels greater than 45 acres is 
threatened. J grants a perpetual easement on a 100-acre parcel of 
forestland that is part of one of the State's scenic areas to a 
qualifying organization. The easement imposes restrictions on the use of 
the parcel for the purpose of maintaining its scenic values. The 
restrictions include a requirement that the parcel be maintained forever 
as open space devoted exclusively to conservation purposes and wildlife 
protection, and that there be no commercial, industrial, residential, or 
other development use of such parcel. The law of State S recognizes a 
limited public right to enter private land, particularly for 
recreational pursuits, unless such land is posted or the landowner 
objects. The easement specifically restricts the landowner from posting 
the parcel, or from objecting, thereby maintaining public access to the 
parcel according to the custom of the State. J's parcel provides the 
opportunity for the public to enjoy the use of the property and 
appreciate its scenic values. Accordingly, J's donation qualifies for a 
deduction under this section.
    Example 2. A qualified conservation organization owns Greenacre in 
fee as a nature preserve. Greenacre contains a high quality example of a 
tall grass prairie ecosystem. Farmacre, an operating farm, adjoins 
Greenacre and is a compatible buffer to the nature preserve. Conversion 
of Farmacre to a more intense use, such as a housing development, would 
adversely affect the continued use of Greenacre as a nature preserve 
because of human traffic generated by the development. The owner of 
Farmacre donates an easement preventing any future development on 
Farmacre to the qualified conservation organization for conservation 
purposes. Normal agricultural uses will be allowed on Farmacre. 
Accordingly, the donation qualifies for a deduction under this section.
    Example 3. H owns Greenacre, a 900-acre parcel of woodland, rolling 
pasture, and orchards on the crest of a mountain. All of Greenacre is 
clearly visible from a nearby national park. Because of the strict 
enforcement of an applicable zoning plan, the highest and best use of 
Greenacre is as a subdivision of 40-acre tracts. H wishes to donate a 
scenic easement on Greenacre to a qualifying conservation organization, 
but H would like to reserve the right to subdivide Greenacre into 90-
acre parcels with no more than one single-family home allowable on each 
parcel. Random building on the property, even as little as one home for 
each 90 acres, would destroy the scenic character of the view. 
Accordingly, no deduction would be allowable under this section.
    Example 4. Assume the same facts as in example (3), except that not 
all of Greenacre is visible from the park and the deed of easement 
allows for limited cluster development of no more than five nine-acre 
clusters (with four houses on each cluster) located in areas generally 
not visible from the national park and subject to site and building plan 
approval by the donee organization in order to preserve the scenic view 
from the park. The donor and the donee have already identified sites 
where limited cluster development would not be visible from the park or 
would not impair the view. Owners of homes in the clusters will not have 
any rights with respect to the surrounding Greenacre property that are 
not also available to the general public. Accordingly, the donation 
qualifies for a deduction under this section.
    Example 5. In order to protect State S's declining open space that 
is suited for agricultural use from increasing development pressure that 
has led to a marked decline in such open space, the Legislature of State 
S passed a statute authorizing the purchase of ``agricultural land 
development rights'' on open acreage. Agricultural land development 
rights allow the State to place agricultural preservation restrictions 
on land designated as worthy of protection in order to preserve open 
space and farm resources. Agricultural preservation restrictions 
prohibit or limit construction or placement of buildings except those 
used for agricultural purposes or dwellings used for family living by 
the farmer and his family and employees; removal of mineral substances 
in any manner that adversely affects the land's agricultural potential; 
or other uses detrimental to retention of the land for agricultural use. 
Money has been appropriated for this program and some

[[Page 158]]

landowners have in fact sold their ``agricultural land development 
rights'' to State S. K owns and operates a small dairy farm in State S 
located in an area designated by the Legislature as worthy of 
protection. K desires to preserve his farm for agricultural purposes in 
perpetuity. Rather than selling the development rights to State S, K 
grants to a qualified organization an agricultural preservation 
restriction on his property in the form of a conservation easement. K 
reserves to himself, his heirs and assigns the right to manage the farm 
consistent with sound agricultural and management practices. The 
preservation of K's land is pursuant to a clearly delineated 
governmental policy of preserving open space available for agricultural 
use, and will yield a significant public benefit by preserving open 
space against increasing development pressures.

    (g) Enforceable in perpetuity--(1) In general. In the case of any 
donation under this section, any interest in the property retained by 
the donor (and the donor's successors in interest) must be subject to 
legally enforceable restrictions (for example, by recordation in the 
land records of the jurisdiction in which the property is located) that 
will prevent uses of the retained interest inconsistent with the 
conservation purposes of the donation. In the case of a contribution of 
a remainder interest, the contribution will not qualify if the tenants, 
whether they are tenants for life or a term of years, can use the 
property in a manner that diminishes the conservation values which are 
intended to be protected by the contribution.
    (2) Protection of a conservation purpose in case of donation of 
property subject to a mortgage. In the case of conservation 
contributions made after February 13, 1986, no deducion will be 
permitted under this section for an interest in property which is 
subject to a mortgage unless the mortgagee subordinates its rights in 
the property to the right of the qualified organization to enforce the 
conservation purposes of the gift in perpetuity. For conservation 
contributions made prior to February 14, 1986, the requirement of 
section 170 (h)(5)(A) is satisfied in the case of mortgaged property 
(with respect to which the mortgagee has not subordinated its rights) 
only if the donor can demonstrate that the conservation purpose is 
protected in perpetuity without subordination of the mortgagee's rights.
    (3) Remote future event. A deduction shall not be disallowed under 
section 170(f)(3)(B)(iii) and this section merely because the interest 
which passes to, or is vested in, the donee organization may be defeated 
by the performance of some act or the happening of some event, if on the 
date of the gift it appears that the possibility that such act or event 
will occur is so remote as to be negligible. See paragraph (e) of Sec. 
1.170A-1. For example, a state's statutory requirement that use 
restrictions must be rerecorded every 30 years to remain enforceable 
shall not, by itself, render an easement nonperpetual.
    (4) Retention of qualified mineral interest--(i) In general. Except 
as otherwise provided in paragraph (g)(4)(ii) of this section, the 
requirements of this section are not met and no deduction shall be 
allowed in the case of a contribution of any interest when there is a 
retention by any person of a qualified mineral interest (as defined in 
paragraph (b)(1)(i) of this section) if at any time there may be 
extractions or removal of minerals by any surface mining method. 
Moreover, in the case of a qualified mineral interest gift, the 
requirement that the conservation purposes be protected in perpetuity is 
not satisfied if any method of mining that is inconsistent with the 
particular conservation purposes of a contribution is permitted at any 
time. See also Sec. 1.170A-14(e)(2). However, a deduction under this 
section will not be denied in the case of certain methods of mining that 
may have limited, localized impact on the real property but that are not 
irremediably destructive of significant conservation interests. For 
example, a deduction will not be denied in a case where production 
facilities are concealed or compatible with existing topography and 
landscape and when surface alteration is to be restored to its original 
state.
    (ii) Exception for qualified conservation contributions after July 
1984. (A) A contribution made after July 18, 1984, of a qualified real 
property interest described in section 170(h)(2)(A) shall not be 
disqualified under the first sentence of paragraph (g)(4)(i) of this 
section if

[[Page 159]]

the following requirements are satisfied.
    (1) The ownership of the surface estate and mineral interest were 
separated before June 13, 1976, and remain so separated up to and 
including the time of the contribution.
    (2) The present owner of the mineral interest is not a person whose 
relationship to the owner of the surface estate is described at the time 
of the contribution in section 267(b) or section 707(b), and
    (3) The probability of extraction or removal of minerals by any 
surface mining method is so remote as to be negligible.

Whether the probability of extraction or removal of minerals by surface 
mining is so remote as to be negligible is a question of fact and is to 
be made on a case by case basis. Relevant factors to be considered in 
determining if the probability of extraction or removal of minerals by 
surface mining is so remote as to be negligible include: Geological, 
geophysical or economic data showing the absence of mineral reserves on 
the property, or the lack of commercial feasibility at the time of the 
contribution of surface mining the mineral interest.
    (B) If the ownership of the surface estate and mineral interest 
first became separated after June 12, 1976, no deduction is permitted 
for a contribution under this section unless surface mining on the 
property is completely prohibited.
    (iii) Examples. The provisions of paragraph (g)(4)(i) and (ii) of 
this section may be illustrated by the following examples:

    Example 1. K owns 5,000 acres of bottomland hardwood property along 
a major watershed system in the southern part of the United States. 
Agencies within the Department of the Interior have determined that 
southern bottomland hardwoods are a rapidly diminishing resource and a 
critical ecosystem in the south because of the intense pressure to cut 
the trees and convert the land to agricultural use. These agencies have 
further determined (and have indicated in correspondence with K) that 
bottomland hardwoods provide a superb habitat for numerous species and 
play an important role in controlling floods and purifying rivers. K 
donates to a qualified organization his entire interest in this property 
other than his interest in the gas and oil deposits that have been 
identified under K's property. K covenants and can ensure that, although 
drilling for gas and oil on the property may have some temporary 
localized impact on the real property, the drilling will not interfere 
with the overall conservation purpose of the gift, which is to protect 
the unique bottomland hardwood ecosystem. Accordingly, the donation 
qualifies for a deduction under this section.
    Example 2. Assume the same facts as in Example 1, except that in 
1979, K sells the mineral interest to A, an unrelated person, in an 
arm's-length transaction, subject to a recorded prohibition on the 
removal of any minerals by any surface mining method and a recorded 
prohibition against any mining technique that will harm the bottomland 
hardwood ecosystem. After the sale to A, K donates a qualified real 
property interest to a qualified organization to protect the bottomland 
hardwood ecosystem. Since at the time of the transfer, surface mining 
and any mining technique that will harm the bottomland hardwood 
ecosystem are completely prohibited, the donation qualifies for a 
deduction under this section.

    (5) Protection of conservation purpose where taxpayer reserves 
certain rights--(i) Documentation. In the case of a donation made after 
February 13, 1986, of any qualified real property interest when the 
donor reserves rights the exercise of which may impair the conservation 
interests associated with the property, for a deduction to be allowable 
under this section the donor must make available to the donee, prior to 
the time the donation is made, documentation sufficient to establish the 
condition of the property at the time of the gift. Such documentation is 
designed to protect the conservation interests associated with the 
property, which although protected in perpetuity by the easement, could 
be adversely affected by the exercise of the reserved rights. Such 
documentation may include:
    (A) The appropriate survey maps from the United States Geological 
Survey, showing the property line and other contiguous or nearby 
protected areas;
    (B) A map of the area drawn to scale showing all existing man-made 
improvements or incursions (such as roads, buildings, fences, or gravel 
pits), vegetation and identification of flora and fauna (including, for 
example, rare species locations, animal breeding and roosting areas, and 
migration routes),

[[Page 160]]

land use history (including present uses and recent past disturbances), 
and distinct natural features (such as large trees and aquatic areas);
    (C) An aerial photograph of the property at an appropriate scale 
taken as close as possible to the date the donation is made; and
    (D) On-site photographs taken at appropriate locations on the 
property. If the terms of the donation contain restrictions with regard 
to a particular natural resource to be protected, such as water quality 
or air quality, the condition of the resource at or near the time of the 
gift must be established. The documentation, including the maps and 
photographs, must be accompanied by a statement signed by the donor and 
a representative of the donee clearly referencing the documentation and 
in substance saying ``This natural resources inventory is an accurate 
representation of [the protected property] at the time of the 
transfer.''.
    (ii) Donee's right to inspection and legal remedies. In the case of 
any donation referred to in paragraph (g)(5)(i) of this section, the 
donor must agree to notify the donee, in writing, before exercising any 
reserved right, e.g. the right to extract certain minerals which may 
have an adverse impact on the conservation interests associated with the 
qualified real property interest. The terms of the donation must provide 
a right of the donee to enter the property at reasonable times for the 
purpose of inspecting the property to determine if there is compliance 
with the terms of the donation. Additionally, the terms of the donation 
must provide a right of the donee to enforce the conservation 
restrictions by appropriate legal proceedings, including but not limited 
to, the right to require the restoration of the property to its 
condition at the time of the donation.
    (6) Extinguishment. (i) In general. If a subsequent unexpected 
change in the conditions surrounding the property that is the subject of 
a donation under this paragraph can make impossible or impractical the 
continued use of the property for conservation purposes, the 
conservation purpose can nonetheless be treated as protected in 
perpetuity if the restrictions are extinguished by judicial proceeding 
and all of the donee's proceeds (determined under paragraph (g)(6)(ii) 
of this section) from a subsequent sale or exchange of the property are 
used by the donee organization in a manner consistent with the 
conservation purposes of the original contribution.
    (ii) Proceeds. In case of a donation made after February 13, 1986, 
for a deduction to be allowed under this section, at the time of the 
gift the donor must agree that the donation of the perpetual 
conservation restriction gives rise to a property right, immediately 
vested in the donee organization, with a fair market value that is at 
least equal to the proportionate value that the perpetual conservation 
restriction at the time of the gift, bears to the value of the property 
as a whole at that time. See Sec. 1.170A-14(h)(3)(iii) relating to the 
allocation of basis. For purposes of this paragraph (g)(6)(ii), that 
proportionate value of the donee's property rights shall remain 
constant. Accordingly, when a change in conditions give rise to the 
extinguishment of a perpetual conservation restriction under paragraph 
(g)(6)(i) of this section, the donee organization, on a subsequent sale, 
exchange, or involuntary conversion of the subject property, must be 
entitled to a portion of the proceeds at least equal to that 
proportionate value of the perpetual conservation restriction, unless 
state law provides that the donor is entitled to the full proceeds from 
the conversion without regard to the terms of the prior perpetual 
conservation restriction.
    (h) Valuation--(1) Entire interest of donor other than qualified 
mineral interest. The value of the contribution under section 170 in the 
case of a contribution of a taxpayer's entire interest in property other 
than a qualified mineral interest is the fair market value of the 
surface rights in the property contributed. The value of the 
contribution shall be computed without regard to the mineral rights. See 
paragraph (h)(4), example (1), of this section.
    (2) Remainder interest in real property. In the case of a 
contribution of any remainder interest in real property, section 
170(f)(4) provides that in determining the value of such interest for 
purposes of section 170, depreciation

[[Page 161]]

and depletion of such property shall be taken into account. See Sec. 
1.170A-12. In the case of the contribution of a remainder interest for 
conservation purposes, the current fair market value of the property 
(against which the limitations of Sec. 1.170A-12 are applied) must take 
into account any pre-existing or contemporaneously recorded rights 
limiting, for conservation purposes, the use to which the subject 
property may be put.
    (3) Perpetual conservation restriction--(i) In general. The value of 
the contribution under section 170 in the case of a charitable 
contribution of a perpetual conservation restriction is the fair market 
value of the perpetual conservation restriction at the time of the 
contribution. See Sec. 1.170A-7(c). If there is a substantial record of 
sales of easements comparable to the donated easement (such as purchases 
pursuant to a governmental program), the fair market value of the 
donated easement is based on the sales prices of such comparable 
easements. If no substantial record of market-place sales is available 
to use as a meaningful or valid comparison, as a general rule (but not 
necessarily in all cases) the fair market value of a perpetual 
conservation restriction is equal to the difference between the fair 
market value of the property it encumbers before the granting of the 
restriction and the fair market value of the encumbered property after 
the granting of the restriction. The amount of the deduction in the case 
of a charitable contribution of a perpetual conservation restriction 
covering a portion of the contiguous property owned by a donor and the 
donor's family (as defined in section 267(c)(4)) is the difference 
between the fair market value of the entire contiguous parcel of 
property before and after the granting of the restriction. If the 
granting of a perpetual conservation restriction after January 14, 1986, 
has the effect of increasing the value of any other property owned by 
the donor or a related person, the amount of the deduction for the 
conservation contribution shall be reduced by the amount of the increase 
in the value of the other property, whether or not such property is 
contiguous. If, as a result of the donation of a perpetual conservation 
restriction, the donor or a related person receives, or can reasonably 
expect to receive, financial or economic benefits that are greater than 
those that will inure to the general public from the transfer, no 
deduction is allowable under this section. However, if the donor or a 
related person receives, or can reasonably expect to receive, a 
financial or economic benefit that is substantial, but it is clearly 
shown that the benefit is less than the amount of the transfer, then a 
deduction under this section is allowable for the excess of the amount 
transferred over the amount of the financial or economic benefit 
received or reasonably expected to be received by the donor or the 
related person. For purposes of this paragraph (h)(3)((i), related 
person shall have the same meaning as in either section 267(b) or 
section 707(b). (See Example 10 of paragraph (h)(4) of this section.)
    (ii) Fair market value of property before and after restriction. If 
before and after valuation is used, the fair market value of the 
property before contribution of the conservation restriction must take 
into account not only the current use of the property but also an 
objective assessment of how immediate or remote the likelihood is that 
the property, absent the restriction, would in fact be developed, as 
well as any effect from zoning, conservation, or historic preservation 
laws that already restrict the property's potential highest and best 
use. Further, there may be instances where the grant of a conservation 
restriction may have no material effect on the value of the property or 
may in fact serve to enhance, rather than reduce, the value of property. 
In such instances no deduction would be allowable. In the case of a 
conservation restriction that allows for any development, however 
limited, on the property to be protected, the fair maket value of the 
property after contribution of the restriction must take into account 
the effect of the development. In the case of a conservation easement 
such as an easement on a certified historic structure, the fair market 
value of the property after contribution of the restriction must take 
into account the amount of access permitted by the terms of the 
easement. Additionally, if

[[Page 162]]

before and after valuation is used, an appraisal of the property after 
contribution of the restriction must take into account the effect of 
restrictions that will result in a reduction of the potential fair 
market value represented by highest and best use but will, nevertheless, 
permit uses of the property that will increase its fair market value 
above that represented by the property's current use. The value of a 
perpetual conservation restriction shall not be reduced by reason of the 
existence of restrictions on transfer designed solely to ensure that the 
conservation restriction will be dedicated to conservation purposes. See 
Sec. 1.170A-14 (c)(3).
    (iii) Allocation of basis. In the case of the donation of a 
qualified real property interest for conservation purposes, the basis of 
the property retained by the donor must be adjusted by the elimination 
of that part of the total basis of the property that is properly 
allocable to the qualified real property interest granted. The amount of 
the basis that is allocable to the qualified real property interest 
shall bear the same ratio to the total basis of the property as the fair 
market value of the qualified real property interest bears to the fair 
market value of the property before the granting of the qualified real 
property interest. When a taxpayer donates to a qualifying conservation 
organization an easement on a structure with respect to which deductions 
are taken for depreciation, the reduction required by this paragraph 
(h)(3)(ii) in the basis of the property retained by the taxpayer must be 
allocated between the structure and the underlying land.
    (4) Examples. The provisions of this section may be illustrated by 
the following examples. In examples illustrating the value or 
deductibility of donations, the applicable restrictions and limitations 
of Sec. 1.170A-4, with respect to reduction in amount of charitable 
contributions of certain appreciated property, and Sec. 1.170A-8, with 
respect to limitations on charitable deductions by individuals. must 
also be taken into account.

    Example 1. A owns Goldacre, a property adjacent to a state park. A 
wants to donate Goldacre to the state to be used as part of the park, 
but A wants to reserve a qualified mineral interest in the property, to 
exploit currently and to devise at death. The fair market value of the 
surface rights in Goldacre is $200,000 and the fair market value of the 
mineral rights in $100.000. In order to ensure that the quality of the 
park will not be degraded, restrictions must be imposed on the right to 
extract the minerals that reduce the fair market value of the mineral 
rights to $80,000. Under this section, the value of the contribution is 
$200,000 (the value of the surface rights).
    Example 2. In 1984 B, who is 62, donates a remainder interest in 
Greenacre to a qualifying organization for conservation purposes. 
Greenacre is a tract of 200 acres of undeveloped woodland that is valued 
at $200,000 at its highest and best use. Under Sec. 1.170A-12(b), the 
value of a remainder interest in real property following one life is 
determined under Sec. 25.2512-5 of this chapter (Gift Tax Regulations). 
(See Sec. 25.2512-5A of this chapter with respect to the valuation of 
annuities, interests for life or term of years, and remainder or 
reversionary interests transferred before May 1, 1999.) Accordingly, the 
value of the remainder interest, and thus the amount eligible for an 
income tax deduction under section 170(f), is $55,996 ($200,000x.27998).
    Example 3. Assume the same facts as in Example 2, except that 
Greenacre is B's 200-acre estate with a home built during the colonial 
period. Some of the acreage around the home is cleared; the balance of 
Greenacre, except for access roads, is wooded and undeveloped. See 
section 170(f)(3)(B)(i). However, B would like Greenacre to be 
maintained in its current state after his death, so he donates a 
remainder interest in Greenacre to a qualifying organization for 
conservation purposes pursunt to section 170 (f)(3)(B)(iii) and 
(h)(2)(B). At the time of the gift the land has a value of $200,000 and 
the house has a value of $100,000. The value of the remainder interest, 
and thus the amount eligible for an income tax deduction under section 
170(f), is computed pursuant to Sec. 1.170A-12. See Sec. 1.170A-
12(b)(3).
    Example 4. Assume the same facts as in Example 2, except that at age 
62 instead of donating a remainder interest B donates an easement in 
Greenacre to a qualifying organization for conservation purposes. The 
fair market value of Greenacre after the donation is reduced to 
$110,000. Accordingly, the value of the easement, and thus the amount 
eligible for a deduction under section 170(f), is $90,000 ($200,000 less 
$110,000).
    Example 5. Assume the same facts as in Example 4, and assume that 
three years later, at age 65, B decides to donate a remainder interest 
in Greenacre to a qualifying organization for conservation purposes. 
Increasing real estate values in the area have raised the fair market 
value of Greenacre (subject to

[[Page 163]]

the easement) to $130,000. Accordingly, the value of the remainder 
interest, and thus the amount eligible for a deduction under section 
170(f), is $41,639 ($130,000x.32030).
    Example 6. Assume the same facts as in Example 2, except that at the 
time of the donation of a remainder interest in Greenacre, B also 
donates an easement to a different qualifying organization for 
conservation purposes. Based on all the facts and circumstances, the 
value of the easement is determined to be $100,000. Therefore, the value 
of the property after the easement is $100,000 and the value of the 
remainder interest, and thus the amount eligible for deduction under 
section 170(f), is $27,998 ($100,000x.27998).
    Example 7. C owns Greenacre, a 200-acre estate containing a house 
built during the colonial period. At its highest and best use, for home 
development, the fair market value of Greenacre is $300,000. C donates 
an easement (to maintain the house and Green acre in their current 
state) to a qualifying organization for conservation purposes. The fair 
market value of Greenacre after the donation is reduced to $125,000. 
Accordingly, the value of the easement and the amount eligible for a 
deduction under section 170(f) is $175.000 ($300,000 less $125,000).
    Example 8. Assume the same facts as in Example 7 and assume that 
three years later, C decides to donate a remainder interest in Greenacre 
to a qualifying organization for conservation purposes. Increasing real 
estate values in the area have raised the fair market value of Greenacre 
to $180.000. Assume that because of the perpetual easement prohibiting 
any development of the land, the value of the house is $120,000 and the 
value of the land is $60,000. The value of the remainder interest, and 
thus the amount eligible for an income tax deduction under section 
170(f), is computed pursuant to Sec. 1.170A-12. See Sec. 1.170A-
12(b)(3).
    Example 9. D owns property with a basis of $20,000 and a fair market 
value of $80,000. D donates to a qualifying organization an easement for 
conservation purposes that is determined under this section to have a 
fair market value of $60,000. The amount of basis allocable to the 
easement is $15,000 ($60,000/$80,000=$15,000/$20,000). Accordingly, the 
basis of the property is reduced to $5,000 ($20,000 minus $15,000).
    Example 10. E owns 10 one-acre lots that are currently woods and 
parkland. The fair market value of each of E's lots is $15,000 and the 
basis of each lot is $3,000. E grants to the county a perpetual easement 
for conservation purposes to use and maintain eight of the acres as a 
public park and to restrict any future development on those eight acres. 
As a result of the restrictions, the value of the eight acres is reduced 
to $1,000 an acre. However, by perpetually restricting development on 
this portion of the land, E has ensured that the two remaining acres 
will always be bordered by parkland, thus increasing their fair market 
value to $22,500 each. If the eight acres represented all of E's land, 
the fair market value of the easement would be $112,000, an amount equal 
to the fair market value of the land before the granting of the easement 
(8x$15,000=$120,000) minus the fair market value of the encumbered land 
after the granting of the easement (8x$1,000=$8,000). However, because 
the easement only covered a portion of the taxpayer's contiguous land, 
the amount of the deduction under section 170 is reduced to $97,000 
($150,000-$53,000), that is, the difference between the fair market 
value of the entire tract of land before ($150,000) and after 
((8x$1,000)+(2x $22,500)) the granting of the easement.
    Example 11. Assume the same facts as in example (10). Since the 
easement covers a portion of E's land, only the basis of that portion is 
adjusted. Therefore, the amount of basis allocable to the easement is 
$22,400 ((8x$3,000)x($112,000/$120,000)). Accordingly, the basis of the 
eight acres encumbered by the easement is reduced to $1,600 ($24,000-
$22,400), or $200 for each acre. The basis of the two remaining acres is 
not affected by the donation.
    Example 12. F owns and uses as professional offices a two-story 
building that lies within a registered historic district. F's building 
is an outstanding example of period architecture with a fair market 
value of $125,000. Restricted to its current use, which is the highest 
and best use of the property without making changes to the facade, the 
building and lot would have a fair market value of $100,000, of which 
$80,000 would be allocable to the building and $20,000 woud be allocable 
to the lot. F's basis in the property is $50,000, of which $40,000 is 
allocable to the building and $10,000 is allocable to the lot. F's 
neighborhood is a mix of residential and commercial uses, and it is 
possible that F (or another owner) could enlarge the building for more 
extensive commercial use, which is its highest and best use. However, 
this would require changes to the facade. F would like to donate to a 
qualifying preservation organization an easement restricting any changes 
to the facade and promising to maintain the facade in perpetuity. The 
donation would qualify for a deduction under this section. The fair 
market value of the easement is $25,000 (the fair market value of the 
property before the easement, $125,000, minus the fair market value of 
the property after the easement, $100,000). Pursuant to Sec. 1.170A-
14(h)(3)(iii), the basis allocable to the easement is $10,000 and the 
basis of the underlying property (building and lot) is reduced to 
$40,000.

    (i) Substantiation requirement. If a taxpayer makes a qualified 
conservation contribution and claims a deduction, the taxpayer must 
maintain written

records of the fair market value of the underlying property before and 
after the donation and the conservation purpose furthered by the 
donation and such information shall be stated in the taxpayer's income 
tax return if required by the return or its instructions. See also Sec. 
1.170A-13(c) (relating to substantiation requirements for deductions in 
excess of $5,000 for charitable contributions made after 1984), and 
section 6659 (relating to additions to tax in the case of valuation 
overstatements).
    (j) Effective date. Except as otherwise provided in Sec. 1.170A-
14(g)(4)(ii), this section applies only to contributions made on or 
after December 18, 1980.
