RUFFIN, Judge.
Henry County Water and Sewerage Authority ("Henry County") petitioned to condemn 5.46 acres of land owned by Collins & Associates ("Collins"). Following a jury trial, Collins was awarded $79,856.01. Collins appeals, challenging evidentiary rulings made by the trial court. In several other enumerations of error, Collins contends that the trial court erred in charging the jury. Finding no reversible error, we affirm.
Viewed favorably to the verdict,[1] the evidence shows that Henry County filed a petition in Henry County Superior Court to condemn 5.46 acres owned by Collins for the purpose of creating a water reservoir. The special master in the case recommended that the property be condemned and that Collins receive $27,100 in compensation. Collins appealed the award, demanding a jury trial. Following a trial at which both Henry County and Collins presented expert testimony regarding valuation, the jury awarded $79,856.01.
1. In its first claim of error, Collins contends that the trial court erred in granting Henry County's motion in limine, thereby excluding evidence of a boundary line dispute.[2] Specifically, Collins argues that because of a boundary dispute, Henry County was taking 9.78 acres rather than the 5.46 acres named in the petition. Henry County argued that, pretermitting the existence of a *571 boundary dispute, it had only taken 5.46 acres and the only issue to be decided was the value of that acreage. The trial court agreed with Henry County, determining that if any additional acreage was flooded after the completion of the reservoir, Collins might have a separate action for inverse condemnation, but that the only issue to be tried at that time was the value of the 5.46 acres already condemned.[3]
We review a trial court's ruling excluding evidence for abuse of discretion.[4] As noted by the trial court, the sole issue to be determined in a condemnation matter is the just and adequate compensation due for property taken.[5] Here, the trial court foundand the record supportsthat Henry County condemned only 5.46 acres owned by Collins. Under these circumstances, the trial court did not abuse its discretion in excluding evidence regarding an alleged boundary dispute.
2. Collins also challenges the ruling of the trial court "excluding evidence of damages caused by the implementation of the Watershed Protection Ordinance." According to Collins, the trial court improperly
exclud[ed] any evidence relating to the effect of the imposition of the Water Quality Critical Overlay on the subject property and, specifically, evidence of the ability to develop the property which is direct evidence of damages resulting from the Watershed Protection Ordinance being implemented and the loss of density in such development caused by that implementation.[6]
However, this is an inaccurate representation of the trial court's ruling. As the trial court noted, "[t]he only issue is value of this land, as it is, with the Watershed Protection Ordinance in its place. . . . [The issue is] [n]ot that the passing of the ordinance caused the damages."[7] Thus, the trial court precluded only that evidence showing that the passage of the ordinance, which was enacted by a legal entity other than the Henry County Water and Sewerage Authority, damaged the property. The trial court did not preclude Collins from establishing the value of the property taken, taking into consideration the existence of the ordinance. To the extent the passing of the ordinance constituted a taking, the trial court ruled that Collins would have to bring suit against the Henry County Board of Commissioners for inverse condemnation.
As the trial court properly found, the only issue to be tried was the just and adequate compensation for the condemned property at the time of the taking.[8] Thus, the trial court was authorized to find that evidence regarding damages caused by the prior passage of an ordinance by the Henry County Board of Commissioners was irrelevant to the issue to be tried. And the trial court did not limit Collins from showing that the value of the property was influenced by the ordinance. "[T]he trial court has wide discretion to admit testimony of questionable relevance."[9] Here, we cannot say that the trial court abused its discretion in excluding such evidence.
3. According to Collins, the trial court abused its discretion in striking part of its expert's testimony related to consequential damages. Although the condemned land *572 was undeveloped, Collins' expert, Allen Aycock, used subdivision plats to establish the value of the property. The trial court excluded this testimony under the reasoning of Dept. of Transportation v. Benton.[10] In so doing, the trial court did not manifestly abuse its discretion.[11]
Again, the sole relevant issue in a condemnation proceeding is the just and adequate compensation for the property taken at the time of the taking.[12] Thus, even if the condemned property could be used for a different purpose, the jury cannot value the property as though the new use had already been accomplished.[13] Rather, the jury may only consider a proposed new use of the property "to the extent that it affects the market value on the date of taking."[14] And a trial court enjoys broad discretion in determining whether an expert's testimony tends to show the former rather than the latter, and its rulings admitting or excluding such evidence will not be disturbed absent manifest abuse of discretion.[15]
In Benton, we found that an expert's value testimony using "hypothetical developed subdivision lots on [the] condemnees' undivided, unimproved tract of land" was inadmissible.[16] Specifically, this Court reasoned that, "[e]ven where a different use [of the land] is probable, the jury cannot evaluate the property as though the new use were an accomplished fact."[17] This rule has been reiterated in several subsequent cases.[18] And this rule has application here, where the evidence shows that the undeveloped property was several miles away from a water source and lacked utilities necessary for development. Under these circumstances, the trial court did not abuse its discretion in striking that portion of Aycock's testimony valuing the property as though it had been subdivided for development.[19]
4. In two enumerations of error, Collins challenges certain jury instructions given by the trial court.[20] It is axiomatic that, in viewing a challenge to jury instructions, we view the charge as a whole in determining whether it contained error.[21] Moreover, "[t]he trial court's failure to give a jury charge in the exact language requested is not error where the charges actually given substantially cover the principles contained in the request."[22]
(a) Collins contends that the trial court erred in charging the jury that "[t]he only issue is what constitutes just and adequate compensation for the property taken." According to Collins, by failing to instruct jurors that the property owner is also entitled to compensation for property damaged, the court misled jurors. However, in reviewing the entire charge, it is apparent that the trial court fully explained that the government must compensate the condemnee for both direct and consequential damages, including *573 the diminished value of the remaining property. Thus, when viewed as a whole, the charge sufficiently informed jurors of the issue to be tried.[23]
To the extent that Collins also attempts to argue that the trial court erred in charging the jury on allegations in the pleadings, we note that this is beyond the scope of the error as enumerated, "[a]nd a party cannot expand [its] enumerations of error through argument or citation in [its] brief."[24]
(b) In its final enumeration of error, Collins asserts that the trial court erred in its charge on "the definition of an arms length transaction."[25] The trial court instructed jurors that "[t]he fair market value of a piece of property is the price which it will bring when it is offered for sale by one who desires, but is not obliged to sell it, and is bought by one who wishes to buy, but is not under a necessity to do so." As this is an accurate statement of the law, we see no error in the giving of this charge.[26]
Judgment affirmed.

[2]  We take this opportunity to remind Collins' counsel of several of this Court's rules regarding briefs submitted to this Court. In particular, Court of Appeals Rule 25(c)(1) mandates that the sequence of arguments in briefs "shall follow the order of the enumeration of errors, and shall be numbered accordingly." Here, Collins has failed to adhere to this rule and, indeed, the appellant has only five argument sections to address six enumerated errors. To the extent we are unable to ascertain which arguments have been addressed, such errors will be deemed abandoned. See S & A Indus. v. Bank Atlanta, 247 Ga.App. 377, 379, 543 S.E.2d 743 (2000).
