LAKE, Chief Justice.

The question presented for review in this case is whether a conditional use municipal zoning permit may be construed to allow residents of a subdivision within the municipality to install gates in a fence that serves as part of a buffer area between the subdivision and an adjoining neighborhood, in order to allow the residents access to portions of their property located within the buffer. The Court of Appeals held that such gates are not permitted. Westminster Homes, Inc. v. Town of Cary Zoning Bd. of Adjust., 140 N.C. App. 99, 106, 535 S.E.2d 415, 419 (2000). For the reasons hereinafter set forth, we affirm.

In 1992, petitioner Westminster Homes, Inc., a residential housing developer, petitioned the Town of Cary to rezone various properties surrounding the Harmony Hill Lane neighborhood to allow for higher density residential subdivisions. Part of this property, designated Tract 3 on Wake County Tax Map 543, later became Westminster's Sherborne subdivision. Homeowners in the Harmony Hill neighborhood filed protest petitions against Westminster's request. After negotiations, which resulted in a formal legal agreement, Harmony Hill residents withdrew their protests, and Westminster agreed to certain developmental restrictions on Tract 3.

Westminster petitioned the Town to rezone its property in accordance with the agreement made with the residents of Harmony Hill. In February 1993, the Cary Town Council approved some of these restrictions as conditional use zoning permit Z-664-92-PUD. This permit provides, in part, as follows:

1. There shall be a 50 foot undisturbed buffer along the northern boundary of Tract 3. . . . A seven-foot treated wood fence shall be constructed and maintained by the developer along the length of the undisturbed buffer where it adjoins Parcels 19, 20, 21, and 22, Wake County Tax Map 515. The fence shall be the same architecturally and of the same materials as the fence currently existing between Preston Woods and the McLaurin Tract. The fence shall be located 45 feet off the property line . . . and it shall be connected to the existing gate over the sewer easement. The fence shall be installed with the minimum of disturbance to the buffer environment. The fence shall be connected at each end to the fences to be constructed under the respective agreements with Hester and McLaurin in order to preserve continuity and integrity. The fence will always be 45 feet from the boundary line or any property corner, and shall intersect at right angles. This fence will be constructed at the time that a grading permit is issued by the Town of Cary and be completed prior to recording any final plats. The integrity and maintenance of this fence will be the responsibility of the developer of Tract 3 or new owner. A deed disclosure and recorded plat shall be made by the developer so as to inform all new residents of the placement, integrity and maintenance of the new fence. Furthermore, a disclosure as to maintenance responsibility shall be part of the recorded plat and be subject to approval of the Town Council of the Town of Cary.

2. There shall be no utility crossings, sewer lines, or greenways in the 50 foot buffer, except where the Town of Cary may require street or utility connections to Parcel 14, Wake County Tax Map 515. The buffer otherwise will remain in its present natural and undisturbed condition, except fencing and plantings.

3. . . . Fast growing and evergreen trees such as Leyland Cypress shall be planted in a type "A" buffer standard to provide both optical and acoustical screening in front of the fence.

Thus, the permit requires, inter alia, that a "50 foot undisturbed buffer" be maintained between the Harmony Hill neighborhood and Tract 3, and that this buffer include a seven-foot high wooden fence offset forty-five feet from the rear property line of Tract 3, which abuts Harmony Hill. The "developer of Tract 3 or new owner" is responsible for the"integrity and maintenance" of the fence, and all new residents are to be made aware of the fence restriction through a deed disclosure and the recorded plat.

With the parties having settled their preliminary differences, plans for the Sherborne development proceeded. On 18 November 1993, the Town of Cary approved a plan for the Sherborne subdivision. In October 1996, intervenor/respondents Jeff and Leigh Thorne moved into the adjacent Harmony Hill neighborhood. On 5 February 1997, Westminster filed the final subdivision plat for the Sherborne subdivision with the Register of Deeds. Both the plan approved in 1993 and the plat filed in 1997 showed that all the land in Tract 3, including the buffer zone, would be subdivided.

In December 1997, petitioners John and Susan Evans and Bakulesh and Vadana Naik purchased lots and homes from Westminster in the Sherborne subdivision. Petitioners' lots abutted the intervenor/respondents' lot in the Harmony Hill neighborhood. Thus, the buffer zone runs along the back of and through petitioners' properties. Approximately one-half of the Evanses' lot and one-quarter of the Naiks' lot are part of the designated buffer area. Even so, these lots, excluding those portions which are in the buffer, are larger than many others in the Sherborne development.

After the individual petitioners occupied their lots, they desired to access the portions of their respective lots located behind the fence in the buffer zone. In December 1997, petitioner Westminster, the developer of Sherborne, built a gate in the fence for the Naiks. On 13 January 1998, the Town staff with the Division of Planning and Zoning advised Westminster that gates were not permitted in the fence. In June 1998, the Evanses installed a gate in that portion of the fence in their backyard.

On 24 June 1998, a zoning enforcement officer for the Town of Cary sent letters to petitioners informing them that they were in violation of conditional use zoning permit Z-664-92-PUD because they had installed gates in the fence. Petitioners filed an appeal to the Town of Cary Zoning Board of Adjustment. On 10 August 1998, the Board of Adjustment held a hearing and heard evidence regarding the appeal, and residents of the Harmony Hill neighborhood, including intervenor/respondents, urged the Board not to allow gates in the fence. Ultimately, the Board upheld the zoning enforcement officer's interpretation of the conditional use permit and the determination that petitioners were in violation of the permit.

Petitioners appealed to Superior Court, Wake County. At this point, the Thornes formally intervened. After a hearing, the court overturned the Board's ruling and ordered that the Sherborne homeowners were permitted to install gates in the fence in order to access that portion of their property located beyond the fence in the buffer area. Intervenor/respondents appealed. The Court of Appeals reversed the trial court, holding that petitioners are prohibited from installing gates in the fence. Westminster Homes, 140 N.C. App. at 106, 535 S.E.2d at 419.

The only issue before this Court is whether petitioners, as residents of the Sherborne subdivision, may install individual access gates in the fence required under the conditional use zoning permit. Petitioners contend that the Board and the Court of Appeals erred in holding that such gates are prohibited under a proper construction of the conditional use zoning permit. We disagree.

"[C]onditional use zoning occurs when a governmental body, without committing its own authority, secures a given property owner's agreement to limit the use of his property to a particular use or to subject his tract to certain restrictions as a precondition to any rezoning." Chrismon v. Guilford County, 322 N.C. 611, 618, 370 S.E.2d 579, 583 (1988). "[T]he practice of conditional use zoning is an approved practice in North Carolina, so long as the action of the local zoning authority in accomplishing the zoning is reasonable, neither arbitrary nor unduly discriminatory, and in the public interest." Id. at 617, 370 S.E.2d at 583; see also N.C.G.S. §§ 160A-381, 160A-382 (1999). "[T]he only use which can be made of the land which is conditionally rezoned is that which is specified in the conditional use permit." Hall v. City of Durham, 323 N.C. 293, 300, 372 S.E.2d 564, 569 (1988).

Thus, a conditional use zoning permit is a specialized form of a municipal ordinance, and it follows that the same rules of construction apply to both. Courts apply the same rules of construction when construing both statutes and municipal zoning ordinances. Cogdell v. Taylor, 264 N.C. 424, 428, 142 S.E.2d 36, 39 (1965) ("The rules applicable to the construction of statutes are equally applicable to the construction of municipal ordinances."); accord Coastal Ready-Mix Concrete Co. v. Board of Comm'rs of Town of Nags Head, 299 N.C. 620, 629, 265 S.E.2d 379, 385 (1980); George v. Town of Edenton, 294 N.C. 679, 684, 242 S.E.2d 877, 880 (1978). "The basic rule is to ascertain and effectuate the intention of the municipal legislative body." George, 294 N.C. at 684, 242 S.E.2d at 880.

Intent is determined according to the same general rules governing statutory construction, that is, by examining (i) language, (ii) spirit, and (iii) goal of the ordinance. [ Coastal Ready-Mix Concrete Co., 299 N.C. at 629, 265 S.E.2d at 385.] Since zoning ordinances are in derogation of common-law property rights, limitations and restrictions not clearly within the scope of the language employed in such ordinances should be excluded from the operation thereof. Yancey v. Heafner, 268 N.C. 263, 266, 150 S.E.2d 440, 443 (1966). Capricorn Equity Corp. v. Town of Chapel Hill Bd. of Adjust., 334 N.C. 132, 138-39, 431 S.E.2d 183, 188 (1993).

We also are mindful of several other principles of general statutory construction as we examine the issue before us. First, "[i]t is a well established principle of statutory construction that a section of a statute dealing with a specific situation controls, with respect to that situation, other sections which are general in their application." State ex rel. Utils. Comm'n v. Lumbee River Elec. Membership Corp., 275 N.C. 250, 260, 166 S.E.2d 663, 670 (1969); accord Three Guys Real Estate v. Harnett County, 345 N.C. 468, 474, 480 S.E.2d 681, 684 (1997); Trustees of Rowan Technical Coll. v. J. Hyatt Hammond Assocs. , 313 N.C. 230, 238, 328 S.E.2d 274, 279 (1985). Second, if the words of a statute are plain and unambiguous, the court need look no further. Walker v. Board of Trustees of N.C. Local Governmental Employees' Ret. Sys., 348 N.C. 63, 65-66, 499 S.E.2d 429, 430-31 (1998); In re Banks, 295 N.C. 236, 239, 244 S.E.2d 386, 388-89 (1978). Finally, if the language is unclear, judicial construction may be required. Banks, 295 N.C. at 239, 244 S.E.2d at 388-89.

Petitioners present a number of arguments to support their position that individual access gates should be allowed in the fence required under the conditional use permit. Petitioners first argue that the Board and the Court of Appeals erred by failing to interpret the term "fence" consistently throughout the permit and with the Town of Cary Unified Development Ordinance. They contend that terms should be interpreted consistently throughout all zoning authorities and that the ordinance should provide a context for the conditional use permit, which would favor allowing individual access gates in all fences. Under the circumstances of this case, we do not agree. The term "fence" is defined in the Cary Unified Development Ordinance as "[a] structure used to delineate a boundary or as a barrier or means of protection, confinement, or screening." Cary, N.C., Unified Development Ordinance § 2.1.4 (1992) (emphasis added). The term "fence" is not expressly defined in permit Z-664-92-PUD. Neither the ordinance nor the permit defines the term "gate." The ordinance does contain, however, language which is instructive in this case. The ordinance states, under the heading "General Rules of Construction," that "[i]n the event of any conflict between the limitations, requirements, or standards contained in different provisions of this Ordinance and applying to an individual use or structure, the more restrictive provision shall apply." Unified Development Ordinance § 2.1.1(b).

We are unable to discover any provision in the Cary Unified Development Ordinance requiring terms to be defined in the exact same manner in both the ordinance and conditional use permits. Moreover, the more specific terms of the conditional use permit, by design, are meant to place additional restrictions on land use and control when applicable. Id.; see also Chrismon, 322 N.C. at 618, 370 S.E.2d at 583-84. Thus, the permit may provide for a fence without gates, even if the ordinance was clear that gates are usually part of a fence. Such is not the case here, as "gates" are not mentioned in the ordinance. The conditional use permit, relating to specific uses and conditions, does not necessarily have to be interpreted consistently with the more general ordinance. Even if we assume, arguendo, that terms must be defined in the same manner throughout all zoning authorities, the ordinance is not specific in this case and thus does not control our understanding of the term "fence." The term "fence" as defined in the ordinance does not specifically provide for gates, and the term "gate" is not defined in either the ordinance or the permit itself.

Petitioners claim that, under this interpretation, there are possible challenges to countless conditional use rezoning permits. We do not agree. Our interpretation of the conditional use permit as specifically applied here and in relation to the ordinance in this regard will not apply more broadly to produce uncertainty and inconsistencies at the local level. Definitions found in conditional use zoning permits can be different from those found for the same terms in general ordinances because conditional use permits are necessarily more specific in application and restriction than general provisions. Conditional use permit "inconsistencies" with more general ordinances are normally contemplated as an acceptable means to require more restrictive uses in a given specific area or location.

Petitioners further contend that, based on the plain language of the conditional use permit, gates are permitted in the fence at issue. They believe that nothing in the conditional use permit suggests that this fence was intended to block an owner's access to his property. As evidence in support of their interpretation, petitioners point to the fact that the Town approved the subdivision and sale of the buffer to homeowners. They contend that it is illogical to suggest that the Town intended to block access to this portion of their land. They argue that with a gate already allowed for the sewer easement, it is inconsistent to say that the continuity and integrity of the fence would be damaged by other gates. However, we believe a close reading of the entire permit suggests that its clear intention was to preclude all gates not expressly provided for in the document.

Thus, we do not agree with petitioners' understanding of the plain language of the permit. Only one gate is expressly mentioned in the permit. This gate was placed in the fence to allow access to an easement for maintenance of the sewer by the Town. The permit does not suggest a reason for any other gates in the fence. Westminster could have easily specified or bargained for additional individual access gates if it had originally so desired. It did not do so.

In addition, all other requirements in the permit support our interpretation that additional gates are not permitted. The permit states that the fence is to be the "same architecturally" as two existing fences, neither of which has a gate. The fence, together with "[f]ast growing and evergreen trees," is to provide "both optical and acoustical screening" between the neighbors. The fence also is connected to other existing fences "in order to preserve continuity and integrity." The language that "[t]he buffer otherwise will remain in its present natural and undisturbed condition, except fencing and plantings," likewise does not suggest the permission of residential access and use; rather, it implies the opposite. It is true that in 1993 the Town did approve Westminster's preliminary plan for Sherborne, which included the subdivision of the buffer area by extension of lateral boundary lines of lots to be sold into the buffer to the adjacent boundary with Harmony Hill. This fact, however, is not a persuasive indication of the intended extent of the permit to include individual access gates. When examined in context, the language of the conditional use permit itself describes a desire for complete separation and privacy for the Harmony Hill neighborhood. Taken together, these requirements do not lead to or support petitioners' conclusion. The careful use of terms and language in the permit conveys a clear desire for privacy through a wide, comprehensive buffer which includes an architecturally compatible fence restricting residential access and use.

Several other facts support our interpretation of the zoning requirements. The drawing of the fence which accompanied the plans submitted to the Town for the Sherborne subdivision did not include gates or an illustration of a gate. The permit also required the fence to be set forty-five feet off the property line and the buffer itself to be left in an "undisturbed" state. The requirement of an "undisturbed" buffer strongly suggests that gates are not permitted. Easy access through such gates may ultimately lead to a change in the fundamental nature of the buffer area. For example, it is undisputed that the five feet of buffer zone on the inside, or petitioners' side, of the fence has not remained in the intended natural state and has gradually become part of petitioners' lawns. Allowing additional gates may, however unintentionally, lead to a gradual degradation of the environment specified in the permit. Taken together, these requirements appear entirely contrary to a desire to provide easy access for Sherborne residents. They do suggest, however, that additional gates are not to be installed in the fence and, perhaps, that the buffer was originally inadvertently subdivided as indicated above.

We also note that the fence, as originally built, contained only the one gate for the sewer easement. This fact is a strong indication of the intent and understanding of the nature of both the fence and the buffer area on the part of the Town and Westminster. See Preyer v. Parker, 257 N.C. 440, 446, 125 S.E.2d 916, 920 (1962) (stating that the conduct of the parties indicating the manner in which they themselves construe the agreement will be given weight in the interpretation of the instrument by the courts). It is quite unusual to build a fence with no gates if such gates were originally contemplated, so that one would have to return and, wastefully, tear the fence apart to later install gates. Even after Westminster had subdivided the lots, it did not include gates for the anticipated homeowners until asked by the individual petitioners. These facts, taken together with the plain language of the permit, are a strong indication that the parties themselves originally understood the permit to exclude individual access gates in the fence. Petitioners further assert that a non-access interpretation will lead to absurd or illogical results. They argue that they will own inaccessible property for which they maintain tax and tort liability. However, without access petitioners will hardly be inviting or allowing other people to make use of the buffer area, and only trespassers would likely gain access to this undisturbed area. We thus conclude that under the circumstances here, there would be no reasonable basis for tort liability absent some willful action. See Nelson v. Freeland, 349 N.C. 615, 632, 507 S.E.2d 882, 892 (1998). With regard to tax liability, the lack of access could potentially reduce petitioners' tax liabilities, in that the residential area of their lots is reduced in value.

Next, petitioners contend that the proper interpretation of the conditional use permit, and zoning ordinances in general, should favor the free use of property. See Yancey, 268 N.C. at 266, 150 S.E.2d at 443. Petitioners thus assert that zoning ordinances should be strictly construed in favor of the landowner and that courts should not presume intent to impose property restrictions beyond those clearly set forth in the permit. While ambiguous zoning statutes should be interpreted to permit the free use of land, as discussed above, no such ambiguity exists here. Even though the buffer and the fence restrict the use of part of these lots, this limitation is permitted under the circumstances. The permit is clear in its restrictions as to use of the buffer area. It is to be "undisturbed." The permit is a result of a compromise bargain, an agreement for higher density development by Westminster in exchange for additional privacy protection for Harmony Hill. Westminster could not have subdivided the property for the Sherborne subdivision without this bargain, which removed respondents' protests to Westminster's proposed rezoning. As the property has now been subdivided and developed, Harmony Hill residents would be left with substantially less than the privacy for which they bargained if gates were permitted under the permit, after giving the full benefit of greater development to Westminster and petitioners.

Furthermore, clear notice of the buffer area and fence was given in petitioners' deeds and the recorded plat. Westminster's sale of the buffer area, not the Board's interpretation of the ordinance, resulted in the contended claim which petitioners now assert. Under the circumstances, the expressed intentions of the permit for an extensive, composite privacy buffer must control. Like the Board, we interpret the zoning ordinance as not permitting additional gates in the fence, even if it restricts the use of land in the Sherborne subdivision in this case.

Petitioners finally assert that if gates are not permitted, this amounts to an unconstitutional taking of their land by the Board. Petitioners raise this issue for the first time on appeal to this Court. This Court has long held that issues and theories of a case not raised below will not be considered on appeal, see, e.g., Smith v. Bonney, 215 N.C. 183, 184-85, 1 S.E.2d 371, 371-72 (1939); Weil v. Herring, 207 N.C. 6, 10, 175 S.E. 836, 838 (1934), and this issue is not properly before this Court. In any event, we do not consider the Board's interpretation of this permit to be an unconstitutional "taking" of petitioners' private property since there was no imposition of new conditions on petitioners' use in this case, in that the Board merely applied already-existing conditions. Further, this permit was not imposed by a legislative or regulatory body, but was requested and negotiated by the parties. Here, Westminster voluntarily assumed these restrictions as a compromise that allowed it to request a higher density residential zoning. "`[O]ne who voluntarily proceeds under a statute and claims benefits thereby conferred will not be heard to question its constitutionality in order to avoid its burdens.'" Bailey v. State, 348 N.C. 130, 147, 500 S.E.2d 54, 64 (1998) (quoting Convent of Sisters of St. Joseph v. City of Winston-Salem, 243 N.C. 316, 324, 90 S.E.2d 879, 885 (1956)).

We conclude that the additional, individual access gates sought by petitioners are not permitted under conditional use zoning permit Z-664-92-PUD. The Board has interpreted the existing conditions of the permit consistently over time, and we hold that its interpretation is reasonable in light of all the circumstances of this case. From the language of the permit, as well as the surrounding facts and circumstances, it is clear that gates, other than the one specified for the sewer easement, are not permitted in the fence. In this case, we are compelled to agree with intervenor/respondents that "[g]ood fences make good neighbors." Robert Frost, Mending Wall, in The Poetry of Robert Frost 33, 33-34 (Edward Connery Lathem ed., Holt, Rinehart and Winston 1969) (1914). Thus, for the reasons discussed above, the decision of the Court of Appeals is

AFFIRMED.
