FORT FAIRFIELD BP, LLC,
Appellant,
v.
GENERAL SERVICES ADMINISTRATION,
Respondent.
Robert Clark, Managing Member, and John Clark, Authorized Representative, of Fort
Fairfield BP, LLC, Falmouth, MA, appearing for Appellant.
David C. Charin, Office of General Counsel, General Services Administration,
Washington, DC, counsel for Respondent.
Before Judges SHERIDAN, ZISCHKAU, and CHADWICK.
SHERIDAN, Board Judge.
The appellant, Fort Fairfield BP, LLC (Fort Fairfield), leases a property to the
respondent, General Services Administration (GSA).  Fort Fairfield appeals the denial of its
claims to recoup a total of $5184.01 in rent payments that GSA withheld pursuant to the
lease agreement’s real estate tax adjustment clause.  GSA withheld $3261.41 in rent
payments relating to the 2021 tax year and $1922.60 relating to the 2024 tax year.
Fort Fairfield challenges GSA’s use of the 2020 tax year as the real estate tax base
when applying the real estate tax adjustment clause for the 2021 and 2024 tax years.  Since
Fort Fairfield’s appeals on its two claims ask the Board to interpret the same lease agreement


CBCA 8169, 8200 2
and decide which tax year is the real estate tax base, the Board consolidated the appeals
pursuant to Rule 19 (48 CFR 6101.19 (2024)).  For the following reasons, we deny Fort
Fairfield’s appeals.
Background
The lease agreement required Fort Fairfield to complete GSA-directed tenant
improvements at Fort Fairfield’s 169 Camden Street, Rockland, Maine, property (the
property).  Once Fort Fairfield completed the tenant improvements and GSA accepted them,
GSA’s lease term was to commence.
In lease amendment 1, dated April 10, 2018, GSA issued Fort Fairfield a notice to
proceed with tenant improvements.  Fort Fairfield completed the tenant improvements, and
lease amendment 2 established July 27, 2018, as the completion date of the improvements. 
At that time, all ordered tenant improvements had been completed, and the amendment also
established July 27, 2018, as the commencement date of the ten-year lease.
On December 12, 2018, GSA issued Fort Fairfield a notice to proceed with additional
tenant improvements.  It tasked Fort Fairfield with procuring and installing signage.  Before
Fort Fairfield completed this work, the City of Rockland (City) reviewed the property for the
2020 tax year.  This review occurred on January 15, 2019, and the City used it to determine
Fort Fairfield’s 2020 real estate tax bill.  Through lease amendment 3, GSA accepted the
signage work as complete on February 1, 2019.  The City’s property review for the 2021 tax
year occurred on May 13, 2020.  The City used this review to determine Fort Fairfield’s 2021
real estate tax bill.
In 2021 and 2024, GSA reviewed the lease agreement and identified the property
taxes for the 2020 tax year, which totaled $18,416.49, as the real estate tax base.  Under the
lease agreement’s real estate tax adjustment clause, when the property’s real estate tax bill
is less than the real estate tax base, GSA receives a rental credit or lump sum payment from
Fort Fairfield.  The amount of the rental credit or lump sum payment is the difference
between the real estate tax bill and the real estate tax base multiplied by percentage of
occupancy.  Section 1.12 of the lease agreement sets GSA’s percentage of occupancy at 100
percent.  Thus, the amount that Fort Fairfield owes GSA, when applicable, is the difference
between the real estate tax bill and the real estate tax base multiplied by one.
For the 2021 tax year, the property’s real estate tax bill totaled $15,155.08.  This was
$3261.41 less than the $18,416.49 real estate tax bill for the 2020 tax base year. 
Consequently, GSA withheld $3261.41 from its subsequent monthly rent payments.  For the
2024 tax year, Fort Fairfield’s real estate tax bill totaled $16,493.89.  This was $1922.60 less
than the real estate tax bill for the tax base year.  As a result, GSA withheld an additional

CBCA 8169, 8200 3
$1922.60 from its rent payments.  In total, GSA withheld $5184.01 for the 2021 and 2024
tax years.
Disagreeing with GSA’s withholding of rent for the 2021 and 2024 tax years,
Fort Fairfield submitted two claims to the contracting officer.  For each claim, Fort Fairfield
argued that the real estate tax base was the 2021 tax year, not the 2020 tax year.  If the 2021
tax year is identified as the real estate tax base year, then, according to Fort Fairfield, GSA’s
rent withholdings for the 2021 and 2024 tax years would be improper.  Fort Fairfield asserted
that there would be no adjustment for 2021 (as there is no tax adjustment in the tax year that
is the real estate tax base) and the real estate tax bill for 2024 was more, not less, than the
2021 real estate tax bill.
The contracting officer denied the claims, and Fort Fairfield timely appealed to the
Board.
Discussion
“Real Estate Tax Base” and “Full Assessment” are the primary lease terms that the
Board must interpret and apply to the facts of these appeals.  Section 2.07 of the lease
agreement defines “Real Estate Tax Base” as follows:
[T]he unadjusted Real Estate Taxes for the first full Tax Year following
commencement of the Lease term.  If the Real Estate Taxes for that Tax Year
are not based upon a Full Assessment of the Property, then the Real Estate Tax
Base shall be the Unadjusted Real Estate Taxes for the Property for the first
full Tax Year for which the Real Estate Taxes are based upon a Full
Assessment.
The lease then defines “Full Assessment” by explaining as follows:
The Property is deemed to be Fully Assessed (and Real Estate Taxes are
deemed to be based on a Full Assessment) only when a Taxing Authority has,
for the purposes of determining the Lessor’s Liability for Real Estate Taxes,
determined a value for the Property taking into account the value of all
improvements contemplated for the Property pursuant to the Lease, and issued
to the Lessor a tax bill or other notice of levy wherein the Real Estate Taxes
for the Full Tax Year are based upon such Full Assessment.  At no time prior
to the issuance of such bill or notice shall the Property be deemed Fully
Assessed.

CBCA 8169, 8200 4
The 2020 tax year is the “first full tax year following commencement of the lease”
because the lease commenced after the beginning of the 2019 tax year.1  What the parties
dispute is whether the taxes for the 2020 tax year were based on a full assessment.  If the
2020 taxes were based on a full  assessment, the 2020 tax year is the real estate tax base.  If,
instead, the taxes for the 2021 tax year were the first real estate taxes based on a full
assessment, the 2021 tax year is the real estate tax base.
Fort Fairfield’s Position
Fort Fairfield interprets “Full Assessment” in the lease to mean an assessment that
values all improvements contemplated under the lease according to their “true market value.” 
Email correspondence from the former City assessor explains that, in 2020, the City
performed a property assessment reevaluation.  The reevaluation updated the construction
cost tables that the City used to assess properties.  The City first used the updated
construction tables when assessing properties for the 2021 tax year.  As a result, the 2021
assessment valued the property at its true market value.  Fort Fairfield wants the Board to
interpret this to mean that taxes for the 2021 tax year were based on a full assessment.
As further evidence that the 2021 assessment is the most accurate, Fort Fairfield
asserts that the 2020 assessment was based on a building permit review.  The basis of this
opinion is that the property’s field card shows the phrase “BLDG PERMIT” next to the entry
for the January 15, 2019, review.  According to Fort Fairfield, assessments based on building
permit reviews are “narrow in scope” and inconsistent “with a complete or thorough
evaluation of the Property’s total market value.”  In contrast, accompanying the field card
entry for the May 13, 2020, review is the phrase “REVIEW PROPERTY.”  Fort Fairfield
believes that this means that the 2021 assessment was the first time the City thoroughly
reviewed the property.
GSA’s Position
GSA relies on an affidavit from the current City assessor to refute appellant’s claim
that the 2020 assessment was an inaccurate building permit review.  Although the current
City assessor did not personally assess the property for tax years 2020 and 2021, she is
familiar with the City’s property assessment protocols.  She explains that the field card entry
for the January 15, 2019, review included the code number “26.”  Code number “26”
typically means that the assessor visited the property.  Additionally, she explains that the
entry for the May 13, 2020, review includes code number “15.”  Code number “15” typically
means that the assessor did not visit the property.  Since the assessor visited the property in

2018. 

CBCA 8169, 8200 5
January 2019, prior to making the 2020 assessment, GSA contends that the 2020 assessment
is more accurate than 2021 assessment where the assessor did not visit the property.
The City assessor also explains that when the City performs annual property
assessments, it takes into account all improvements made to the property as of April 1 of the
year preceding the tax year.  In other words, April 1 is the City’s assessment date.  According
to the City assessor, this means that the 2020 assessment considered the value of all
improvements completed as of April 1, 2019.  Fort Fairfield completed all tenant
improvements prior to April 1, 2019.  As evidence of this, she points to the assessor’s field
notes from the January 15, 2019, review, which describe the building as “completed
construction.”  Therefore, GSA argues that the 2020 assessment was a full assessment.
Interpretation of the Lease Agreement
When interpreting a lease agreement, its “language should be given the plain meaning
that would be derived by a reasonably intelligent person acquainted with the
contemporaneous circumstances.”  Rafael Portillo v. General Services Administration,
CBCA 2516, 12-1 BCA ¶ 34,925, at 171,737.  The inquiry ends if “the plain language . . . is
unambiguous.”  GEO Group, Inc. v. Department of Justice, CBCA 7168, 23-1 BCA
¶ 38,411, at 186,642.
The lease states that a “Full Assessment” must “determine[] a value for the Property
taking into account the value of all improvements contemplated for the Property pursuant to
the Lease.”  Focusing on whether the assessment relies on the most up-to-date assessment
tools and methods goes beyond the plain language of the agreement.  The lease agreement
is silent on the accuracy of the methods or tools used to assess the property.  Instead, the
definition focuses on whether the assessed value considers all the tenant improvements
memorialized in the lease agreement.
One of our predecessor boards, the General Services Board of Contract Appeals
(GSBCA), also interpreted the term “Full Assessment” in the context of a lease agreement’s
tax adjustment clause and focused on whether all tenant improvements were complete prior
to the assessment.  Kimbrell v. General Services Administration, GSBCA 11325, 93-2 BCA
¶ 25,665, at 127,684 (1992), aff’d, 15 F.3d 175 (Fed. Cir. 1994); see also Otto K. Wetzel,
GSBCA 7466, 85-2 BCA ¶ 18,099, at 90,860.  The Court of Appeals for the Federal Circuit,
considering an appeal of one of those GSBCA decisions, recognized “that there can be no
‘full assessment’ of a property until all improvements contemplated in the lease have been
made.  Thus, ‘full’ means an assessment on the improved property.”  Kimbrell v. Fischer, 15
F.3d 175, 178 (Fed. Cir. 1994) (citing Wetzel, 85-2 BCA at 90,858).
While this refutes Fort Fairfield’s interpretation of “Full Assessment,” it is unclear if
to be fully assessed all tenant improvements need to be complete prior to the assessor

CBCA 8169, 8200 6
reviewing the property or prior to the taxing authority’s assessment date.  The signage work
was incomplete on January 15, 2019, when the assessor reviewed the property.  Fort
Fairfield, however, completed this work by February 1, 2019, which was before the April 1,
2019, assessment date.
While the statement from the City assessor supports the latter, we look to case law for
further clarification.  In Kimbrell, the Federal Circuit agreed with the core rationale in Wetzel
and held that a full assessment can only occur “after all improvements contemplated in the
lease have been made.”  Kimbrell, 15 F.3d at 178.  In Wetzel, the taxing authority assessed
a property sometime between January 1 and May 1, 1981.  Wetzel, 85-2 BCA at 90,860. 
Regardless of when the assessor actually made the assessment, the taxing authority
considered the property valued as of January 1, 1981.  Id. The lessor completed tenant
improvements after January 1, 1981.  Id.  Since the lessor completed the tenant
improvements after the January 1, 1981, assessment date, the GSBCA held that the 1981
assessment was not a full assessment.  Id.
We read Wetzel and the cases interpreting it as holding that an assessment can only
be a full assessment if all improvements contemplated in the lease are complete before the
taxing authority’s assessment date.  That happened here.  All tenant improvements were
complete before the City’s assessment date for the 2020 tax year (i.e, April 1, 2019). This
means the 2020 assessment accounted for all of the tenant improvements and therefore was
a full assessment of the property.
The taxes for the 2020 tax year were based on a full assessment.  As explained
previously, it was also the first full tax year after the lease commenced.  Therefore, GSA
correctly used the 2020 tax year as the real estate tax base when implementing the real estate
tax adjustment clause.
