KIRSHBAUM, Justice.
The appellant, Senior Corp. (Senior), appeals the district court’s judgment affirming a decision of the Board of Assessment Appeals (BAA) which approved a tax levied by the Denver Southeast Suburban Water and Sanitation District (the District) on real property owned, at the time the taxes were levied, by Terracor, Inc. (Terracor), Senior’s predecessor-in-interest. The district court rejected Senior’s challenge to the constitutionality of the levy, but ordered the levy set aside because the District failed to have it approved by the Douglas County Board of County Commissioners (the Commissioners), as provided in section 32-1-207(2), 13 C.R.S. (1984 Supp.). The court also ordered that the tax would be reinstated in the event such approval were obtained. On appeal, Senior challenges the constitutionality of the levy,
asserts that the District had no authority to impose the tax, and argues that the levy was invalid because the District failed to follow requisite statutory procedures. The District cross-appeals that portion of the district court’s order requiring it to seek approval of the levy from the Commissioners. We affirm in part, reverse in part and remand the cause with directions.
I
The facts material to this appeal are not disputed. The Denver Southeast Suburban Water and Sanitation District encompasses an area between Parker and Franktown in Douglas County. During the time pertinent to this lawsuit, Terracor owned much of the property within the District and planned to develop a residential community called “the Pinery” on this land. In 1970, the District and Terracor entered into an agreement providing for the financing, installation and operation of water and sewer service to the Pinery; subsequently, an initial service plan was formulated which projected the development, costs and revenues of water and sewer services for a portion of the Pinery. A supplement to this agreement was executed in 1973 and a new service plan, encompassing the original as well as a new service area, was issued in 1974. The service plans were submitted to and approved by the Douglas County Board of County Commissioners.
Development of the Pinery proceeded under Terracor’s direction. The District designed and installed water and sewer facilities in the manner requested by Terracor. These installations consisted of “town-wide” facilities — major systems designed to serve more than one subdivision — and “in-tract” facilities — systems designed and constructed to serve a single subdivision and the lots therein exclusively. Development, however, did not proceed as rapidly as projected in either the 1971 or 1974 service plans.
Fewer parcels were subdivided,
1.e.,
platted for development, than anticipa
ted, and one platted area had been vacated prior to development. Also, fewer houses and multiple-family structures had been connected to water and sewer systems than projected. As a consequence of slow development, revenue to the District in the form of tap fees, connection fees and service charges fell below expectations.
In 1979, Terracor and the District executed a new contract which rescinded and replaced the 1970 and 1973 agreements. This agreement expressly granted the District “the right to preserve its financial integrity, and to exercise independent judgment in making decisions relative to the expansion of its water and sewer utility systems.” It defined “financial integrity,” in part, as contemplating increases in the District’s general
ad valorem
taxes, connection fees, tap fees, readiness-to-serve charges, and service charges. By the time this litigation commenced, Terracor had experienced serious financial difficulties and development of the Pinery by it had ceased.
A study conducted in 1981 by engineering consultants for the District concluded that approximately thirty percent of the capital costs of town-wide water and sewer facilities in the Pinery, or a sum of $1,202,-256, had been incurred by the District to serve property that remained unplatted. The interest on the bonded indebtedness of the District attributable to these facilities was $82,999. On October 30, 1981, the District adopted its budget for fiscal year 1982 which determined that this interest should be paid by the property for which those facilities had been installed. The budget thus divided the District into two areas for tax purposes. Ten unplatted parcels for which town-wide facilities had been constructed constituted the first area and were taxed at a rate of 530 mills per dollar of assessed valuation. All of these parcels were then owned by Terracor. All other land within the District, which consisted of platted subdivisions that were served by both town-wide and in-tract facilities and unplatted land outside the area served by town-wide facilities, comprised the second area and was taxed at a rate of 15 mills.
The ten Terracor parcels subject to the tax levy of 530 mills had an assessed valuation in 1981 of $150,580; the tax from this levy totalled $79,807.40 for 1982.
Terra-cor petitioned the Commissioners to abate taxes in this amount. The petition was denied on December 22, 1981, and Terracor filed an appeal with the BAA.
The District intervened as a party respondent in this proceeding. The BAA affirmed, holding that the District “acted within its statutory authority, as provided in [section] 32-1-1006
et seq.,
[13 C.R.S. (1984 Supp.) ] in setting different mill levies for different areas within the District.”
Terracor then filed a complaint for judicial review of the BAA’s order, pursuant to section 24-4-106, 10 C.R.S. (1982), of the
State Administrative Procedure Act.
Ter-racor also sought declaratory relief pursuant to sections 13-51-101 to -115, 6 C.R.S. (1973 & 1984 Supp.), and C.R.C.P. 57. The district court concluded that the tax did not violate constitutional requirements of uniformity and upheld the authority of the District to classify property according to services and facilities furnished. However, the court ruled that the 530 mill levy constituted a material modification of the 1974 service plan and, therefore, was subject to the requirement in section 32-1-207(2), 13 C.R.S. (1984 Supp.), of approval by the Commissioners. The district court then set aside the BAA order and ordered the cause remanded to the BAA to set aside the order of the Commissioners “pending compliance by the District with [section] 32-1-207(2).” The court further ordered that the BAA order be reinstated in the event the Commissioners approved the District’s levy. This appeal followed.
II
Senior contends that the District’s tax levies violate the uniform taxation provision of article X, section 3, of the Colorado Constitution. Although Senior denominates its argument as an attack on section 32-l-1006(l)(b), 13 C.R.S. (1984 Supp.), “as applied,” portions of its argument in effect challenge the validity of the statute on its face.
We reject Senior’s argument.
Section 32-l-1006(l)(b) provides in part: [T]he board of any sanitation, water and sanitation, or water district has the following powers for and on behalf of such district:
(b)(1) To divide such district into areas according to the water or sanitation services furnished or to be furnished therein. The board has the power to fix different rates, fees, tolls, or charges and different rates of levy for tax purposes against all of the taxable property within the several areas of such district according to the services and facilities furnished or to be furnished therein within a reasonable time....
(II) If the board divides a special district into areas according to the facilities and services furnished or to be furnished, to determine the amount of money necessary to be raised by taxation within each such area, taking into consideration other sources of revenue within the area, and to fix a levy which, when levied upon every dollar of the valuation for assessment of taxable property within such area of the special district, will supply funds for the payments of the costs of acquiring, operating, and maintaining the services or facilities furnished in such area and will pay promptly, when due, the principal or interest on bonds or other obligations issued and its pro rata share of the general operating expenses of the district.
The BAA and the district court held that the District acted within the powers granted by this statute, and Senior does not dispute that conclusion here. Senior argues, however, that any statutory scheme that results in different tax levies on various geographical areas within the territori
al limits of the taxing authority violates article X, section 3, of the Colorado Constitution.
When the District adopted its budget for fiscal year 1982, section 3 of article X provided, in pertinent part as follows:
All taxes shall be uniform upon each of the various classes of real and personal property located within the territorial limits of the authority levying the tax....
This provision is applicable only to
ad valo-rem
property taxes,
see, e.g., Colorado Department of Social Services v. Board of County Commissioners,
697 P.2d 1 (Colo. 1985), and thus applies to the District’s tax levy. It requires “that the burden of taxation be uniform on the same class of property within the jurisdiction of the authority levying the tax.”
Denver Urban Renewal Authority v. Byrne,
618 P.2d 1374, 1386 (Colo.1980).
Of course, any classification of real property necessarily results in disparate groupings of property of a like class. Section 32-l-1006(l)(b) authorizes districts to divide themselves into taxing areas “according to the water or sanitation services furnished or to be furnished therein.” § 32--l--1006(l)(b)(I), 13 C.R.S. (1984 Supp.). In substance, the statute permits water and sanitation districts to classify property according to the levels of services extended to the property. Such classifications inevitably' create different taxes on different property, whether the property is analyzed as a “class” or as a “geographical area.” The mere fact that a particular classification scheme results in different tax rates on different geographical areas of property does not establish a violation of the constitutional requirement of uniformity.
By its reference to “various classes” of real and personal property, section 3 implicitly recognizes the power of the General Assembly to classify property for tax purposes and to prescribe various methods for ascertaining the value of the different classes.
See Ames v. People ex rel. Temple,
26 Colo. 83, 56 P. 656 (1899). When the General Assembly has exercised this authority, the resulting classification must be reasonable.
See American Mobile Home Association, Inc. v. Dolan,
191 Colo. 433, 553 P.2d 758 (1976);
District 50 Metropolitan Recreation District v. Burnside,
167 Colo. 425, 448 P.2d 788 (1968). In
Dolan,
wherein we upheld the General Assembly’s power to classify movable structures differently than conventional residences, the test was described as follows:
If the classification conceivably rests upon some reasonable considerations of difference or policy, there is no constitutional violation. The burden is therefore on the one attacking the classification to negative every conceivable basis which might support it....
191 Colo. at 438, 553 P.2d at 762. In
Burnside,
we concluded that a statute exempting certain types of property from tax levies imposed to support recreation districts did not violate constitutional requirements, noting that the classification’s reasonableness was “apparent in the statute itself from a consideration of the type of district involved and of the type of property excluded.” 167 Colo. at 431, 448 P.2d at 791.
In this case, the District classified property within its boundaries according to the extension of water and sewer services to the property. It concluded essentially that the unplatted Terracor property differed from other property in the District because, unlike other unplatted land within the District, it had been supplied with town-wide water and sewer facilities, and,
unlike platted land in the District, it had not been furnished with in-tract facilities. Senior does not challenge the fact that these differences exist between the two areas or assert that such a classification is unreasonable. Nor does Senior contend that the District improperly applied section 32~l-1006(l)(b) in establishing these areas. Rather, it argues that the taxing program adopted by the District is prohibited by our decision in
Pueblo Junior College District v. Donner,
154 Colo. 26, 387 P.2d 727 (1963), because it imposes unequal levies on different geographical areas within the taxing authority’s territory. We disagree.
In
Donner,
this court found unconstitutional a statute for funding Colorado’s junior colleges because, although it was a state tax, it expressly exempted certain property within the state from that tax.
See id.
at 30-31, 387 P.2d at 730. The funding bill exempted property on two bases: location in a portion of a county included in a junior college district, and location in a county where certain other levies exceeded express limits.
See
House Bill No. 360, ch. 219, sec. 8, 1961 Colo.Sess.Laws 688, 690. The exemptions did not rest on any difference in the nature of the property in different counties, and residents of any county could attend a junior college of their choice. Because the exempt and nonexempt property were similarly situated, we concluded that the exemptions were prohibited by section 6 of article X of the Colorado Constitution as it then existed
and resulted in a non-uniform tax burden prohibited by section 3 of that article. We did not, however, address the validity of different tax levies applied to dissimilarly situated property. Here, the District has enacted a program which taxes dissimilar property at different rates.
Donner
does not preclude such a taxation system.
Senior also relies on authority from other jurisdictions in support of its argument that the District may not designate separate taxing areas within its territorial limits. These cases rest on distinguishable factual and legal grounds.
In
Celanese Corp. v. Strange,
272 S.C. 399, 252 S.E.2d 137 (1979), the South Carolina Supreme Court held unconstitutional a statute permitting special districts to annex contiguous areas and to tax those annexed areas in amounts based upon services received. The dispute arose when a fire and sewer district voted to annex an area that had requested fire protection services only and to tax the new area at one-half the rate applied to property in existing portions of the district. The court found such action to violate the uniform taxation provisions of the South Carolina Constitution, S.C. Const, art. X, §§ 1, 5. However, the classification of property and respective rates of assessment are explicitly set forth in article X, section 1, of that state’s constitution and no provision of that constitution permits classification based upon the provision of services. The legislative power to classify is not so constrained under our constitution; thus
Strange
does not control the issue here raised.
Senior also relies upon the decision in
Anderson v. City of Asheville,
194 N.C. 117, 138 S.E. 715 (1927), wherein the Supreme Court of North Carolina concluded that a statute dividing the City of Asheville into three zones for taxing purposes violated requirements of uniform taxation then in that state’s constitution.
See
N.C. Const, art. V, § 3, and art. VII, § 9 (1868, amended 1962 & 1969). The Constitution of North Carolina then in effect contains no reference to any legislative authority to create classes of property for taxation purposes, however. Thus,
Anderson
does not control the interpretation of our quite different constitutional framework.
Senior also cites
State v. Inhabitants of Raritan,
52 N.J.L. 319, 19 A. 610 (1890), in support of its argument. In this early case, the New Jersey Supreme Court found unconstitutional a statute authorizing townships to divide into streetlamp districts on the ground that the state legislature had no power to establish, or to delegate the power to establish, districts smaller in area than political subdivisions as a basis for imposing taxes. Although the decision did not make reference to any particular constitutional provision, it appears that the New Jersey Constitution then in effect did not refer to property classifications.
See
N.J. Const, art. IV, § 7, ¶ 12 (1844, added 1875, amended 1947 & 1963). The decision turned on the court’s concern that inhabitants of streetlamp districts would have no voice in the disposition of the money raised by the proposed tax.
Inhabitants of Raritan,
52 N.J.L. at 321, 19 A. at 610. In marked contrast, water and sanitation districts in Colorado have been authorized, since their inception, to exercise an array of powers not enjoyed by New Jersey’s streetlamp districts, and the governing boards of Colorado’s water and sanitation districts are elected by the taxpayers of such districts.
See
ch. 175, sec. 7, 12-13, 1939 Colo.Sess.Laws 597, 599-604. Thus,
Inhabitants of Raritan
provides no support for Senior’s position.
A recent decision by the Oregon Supreme Court,
Jarvill v. City of Eugene,
289 Or. 157, 613 P.2d 1 (1980), interpreting a uniform taxation clause in that state’s constitution which contains language almost identical to the language of article X, section 3, of Colorado’s constitution, is consistent with our resolution of this issue. In
Jarvill,
taxpayers challenged the validity of an amendment to the charter of the City of Eugene, Oregon, that permitted the city to establish a downtown development district. Pursuant to the charter amendment, the Eugene City Council enacted an ordinance levying
ad valorem
taxes on real property within the district to finance a portion of the costs of programs designed to develop the downtown district. Contending that the only common characteristic of the property was location within the district, the taxpayers asserted that constitutional requirements of uniform taxation prohibited classification of property for taxation purposes on the basis of geographical location.
The Oregon Constitution provides, in pertinent part, that “all taxation shall be uniform on the same class of subjects within the territorial limits of the authority levying the tax.” Or. Const, art. I, § 32. In
Jarvill,
the Oregon Supreme Court held that this constitutional provision did not prohibit geographical classification “as long as the
geographical
area defined as the District is a valid class.”
Jarvill,
289 Or. at 179, 613 P.2d at 13 (emphasis in original). The court explained its conclusion as follows:
[A] classification based on or defined by geographical location is nevertheless constitutionally permissible if it is also based upon qualitative differences that distinguish the geographical area from other areas within the territorial limits of the authority levying the tax. In other words, a taxing authority may not single out a subterritory for exclusive tax treatment (either taxation or exemption) if that subterritory is indistinguishable from the rest of the territory. But if the subterritory is different in quality compared to the rest of the territory, then
article I, section 32, does not prohibit a taxing authority from defining the sub-territory as a separate class.
Id.
at 180, 613 P.2d at 13. Finding that the creation of a downtown development district rested upon qualitative differences between Eugene’s urban core area and other portions of the city, the court upheld the charter amendment and taxation ordinance. The
Jarvill
rationale is consistent with our decisions in
American Mobile Home Association, Inc. v. Dolan,
191 Colo. 433, 553 P.2d 758 (1976), and
District 50 Metropolitan Recreation District v. Burnside,
167 Colo. 425, 448 P.2d 788 (1968). Applying this principle to this case leads to the conclusion that the division of the District into taxing areas on the basis of services furnished does not contravene the uniform taxation provision of article X, section 3, of the Colorado Constitution.
Senior also contends that the division of District territory into two taxing areas is unauthorized because no specific constitutional provision permits such action. The argument appears to challenge the authority of the General Assembly to delegate such authority to special districts. We believe this argument rests on a fundamental misconception of state constitutional powers.
The Colorado Constitution vests the General Assembly with the plenary power to adopt general laws, subject only to the limitations of the Colorado and United States Constitutions.
See In re Y.D.M.,
197 Colo. 403, 407, 593 P.2d 1356, 1359 (1979);
City & County of Denver v. Lewin,
106 Colo. 331, 105 P.2d 854 (1940). Thus, particular legislation is not susceptible to challenge on the ground that the subject matter is not expressly encompassed within the constitution. Rather, legislation may be declared unconstitutional only when it is prohibited by some particular constitutional limitation.
See In re Y.D.M.,
197 Colo. at 407, 593 P.2d at 1359. The constitution does not limit the General Assembly from classifying property according to appropriate geographical considerations, nor does it limit the General Assembly from delegating such authority to local governmental units of the state. Therefore, the District’s action and the statute authorizing it are not invalid on the grounds that they were not specifically authorized in some part of the constitution.
In conclusion, we hold that the disparate tax levies of the District are authorized by section 32-l-1006(l)(b), 13 C.R.S. (1984 Supp.), and that this statute, as applied and on its face, does not contravene the uniform taxation provision of article X, section 3, of the Colorado Constitution.
Ill
Senior next appears to assert that the General Assembly has, in articles 1 to 13 of Title 39, 16B C.R.S. (1982 & 1984 Supp.), appropriated to itself the sole constitutional authority to classify property for tax purposes, and that, therefore, the District had no authority under section 32-l-1006(l)(b), 13 C.R.S. (1984 Supp.), to classify property for assessment purposes in a manner different from the categories defined in Title 39. Senior reaches this conclusion on the basis of the following statement of purpose contained in section 39-1-101, 16B C.R.S. (1982): “The general assembly declares that its purpose in enacting articles 1 to 13 of this title is to exercise the authority granted in section 3 of article X of the state constitution....”
Senior argues that by this language the General Assembly has determined that the taxing authority granted by article X, section 3, of the constitution is to be exercised exclusively by means of the provisions of Title 39.
This argument ignores the language of section 32-l-1006(l)(b) which expressly permits the District to adopt the classification here challenged. In construing different statutory provisions addressing the same topic, this court must make every effort to give full effect to the legislative purpose of all such provisions.
See Colorado Department of Social Services v. Board of County Commissioners,
697 P.2d 1 (Colo.1985). Adoption of Senior’s argument would in effect nullify the provisions of Title 32 granting authority to special districts to classify property — a result contrary to the express language of section 32-1-1006, not suggested in any fashion by the broad language of section 39-1-101, and not supported by any decisions of this court.
We also observe that article X, section 7, of the Colorado Constitution authorizes the General Assembly to “by law, vest in the corporate authorities [of any county, city, town or other municipal corporation] respectively, the power to assess and collect taxes for all purposes of such corporation.” While this constitutional provision does not directly address the question of authority to make classifications, it does grant broad power to the General Assembly to vest comprehensive taxation power in political subdivisions. It is consistent with the General Assembly’s broad legislative authority,
see In re Y.D.M.,
197 Colo. 403, 593 P.2d 1356, to recognize that the General Assembly may delegate to municipal corporations, as part of their authority to tax for local purposes, the power to classify property for taxation in accordance with services furnished to the property by the corporation.
The language of section 39-1-101 simply recognizes the constitutional basis
for the legislation contained in Title 39. We reject the suggestion that this statute reflects an intent by the General Assembly to prohibit itself from adopting other statutes dealing with the imposition of property taxes in the exercise of its constitutional authority, and reaffirm our previous conclusion that the District’s classification of Senior’s property was expressly authorized by section 32-l-1006(l)(b).
IV
Senior finally contends that the district court erred in ruling that the District could reinstate its levy in the event it obtained the approval of the Commissioners for the levy pursuant to section 32-1-207(2), 13 C.R.S. (1984 Supp.). The District argues in its cross-appeal that it is not subject to section 32-1-207(2) and that, even if its conduct is governed by that statute, its action does not constitute a “material modification” of the original service plan. We conclude that the District is not subject to the requirements of section 32-1-207(2); therefore, we do not address Senior’s final argument.
Section 32-1-207(2), 13 C.R.S. (1984 Supp.), provides in pertinent part as follows:
After the organization of a special district pursuant to the provisions of this part 2 and part 3 of this article, material modifications of the service plan as originally approved may be made by the governing body of such special district only by petition to and approval by the board of county commissioners in substantially the same manner as is provided for the approval of an original service plan.... Such approval of modifications shall be required only with regard to changes of a basic or essential nature, including any addition to the types of services provided by the special district, and shall not be required for changes of a mechanical type necessary only for the execution of the original service plan or for changes in the boundary of the special district.
The District contends that it was not organized “pursuant to the provisions of this part 2 and part 3 of this article.” We agree.
In 1981, the General Assembly consolidated the statutory provisions applicable to Colorado’s various special districts into a single act entitled the “Special District Act” (the 1981 Act).
See
ch. 382, sec. 1, § 32-1-101, 1981 Colo.Sess.Laws 1542, 1542. Section 32-1-207(2) is based upon a nearly identical provision of the “Special District Control Act” of 1965 (the • 1965 Act).
See
ch. 225, sec. 9(3), § 89-18-9(3), 1965 Colo.Sess.Laws 887, 892.
In tracing
the history of the current section 32 — 1— 207(2), we conclude that special districts organized pursuant to legislation that preceded the 1965 Act are not subject to the provisions of that act or section 32 — 1— 207(2).
By its terms, the 1965 Act applied “to any petition for the formation of any
proposed
‘special district’ filed in any district court of competent jurisdiction.”
Id.
sec. 3, § 89-18-3, at 887 (emphasis added). It required the organizers of any proposed special district to file a service plan with the appropriate board of county commissioners and required any petition filed in a district court to be accompanied by a resolution of such board approving the service plan of the proposed district.
Id.
sec. 4, 5, §§ 89-18-4, -5, at 887-88. A special district organized under the 1965 Act could make “material modifications” of its original service plan “only by petition to and approval by the board of county commissioners in substantially the same manner as is provided for the approval of an original service plan.”
Id.
sec. 9(3), § 89-18-9(3), at 892. Thus, a special district that was not subject to the 1965 Act could materially modify the services it provided without obtaining prior approval of the county commissioners.
The 1965 Act also exempted special districts that filed petitions for organization prior to the effective date of that legislation, as follows:
Any petition for the formation of a special district filed in any district court of appropriate jurisdiction prior to May 1, 1965, shall pursue to its conclusion, notwithstanding the provisions of this act. Any petition for the formation of a special district filed in any district court of appropriate jurisdiction after May 1, 1965, shall be subject to the provisions of this act.
Id.
sec. 10, § 89-18-10, at 892. In this case, the District’s petition for organization was filed on April 26, 1965.
Because the provisions of the 1965 Act did not govern the District’s petition, the District was not “organized pursuant to” that statute. Consequently, the District was not subject to the provision of the 1965 Act requiring prior approval by appropriate county commissioners before adopting material modifications to its service plan.
The Special District Control Act of 1965 was repealed and reenacted as part 2 of the Special District Act of 1981.
See
ch. 382, sec. 1, 1981 Colo.Sess.Laws 1542, 1547-51. Section 32-1-201, 13 C.R.S. (1984 Supp.), now limits the general applicability of part 2 of the 1981 Act to “any petition for the
organization
of any proposed special district filed in any district court of competent jurisdiction_” (emphasis added).
This provision merely reiterates the applicability provision of the 1965 Act and does not expand the matters subject to it. Furthermore, the particular provision at issue in this case contained its own limitations; section 32-1-207(2) applies only to circum
stances which might develop “[a]fter the organization of a special district
pursuant to the provisions of this part 2 and part 3 of this article.
” (emphasis added).
The reenactment of the 1965 Act as part 2 of the 1981 Act did not alter the District’s status with regard to this provision. The District was not organized pursuant to part 2 and part 3 of the 1981 Act. Considering the history and purposes of this legislation, we agree with the District that because its petition for organization was not governed by the 1965 Act, its taxing plan is not now subject to the requirements of section 32-1-207(2).
Senior asserts that section 32-1-308(1), 13 C.R.S. (1984 Supp.), subjects all special districts to the provisions of section 32-1-207(2). Section 32-1-308(1) provides in pertinent part as follows:
The provisions of this article which become effective July 1, 1981, shall apply to all special districts existing on June 30, 1981, or organized thereafter; except that any such existing district need not obtain a name change to conform to this article and that any district may continue to operate for the purpose or purposes for which it was organized.
The District did, of course, exist on June 30, 1981. However, when particular provisions of a statute contain their own conditions on applicability, the statute can be “applied” only to the extent and upon the subject permitted by such special provisions.
Cf
§ 2-4-205, IB C.R.S. (1980) (special provision prevails over general one if in conflict). Section 32-1-207(2) expressly limits its application to special districts organized pursuant to specified parts of the 1981 Act. We have concluded that the District was not organized pursuant to such authority; thus, section 32-1-207(2), when applied to the District as part of the 1981 Act, results in the exemption of the District from the requirement of obtaining approval from the Commissioners before modifying its basic service plan.
V
In summary, we affirm the district court’s judgment that section 32-1-10Ó6(l)(b), 13 C.R.S. (1984 Supp.), is constitutional on its face and as applied to Senior in this case. We also affirm the district court’s conclusion that the District acted within its constitutional and statutory authority in classifying property for purposes of imposing
ad valorem
property taxes according to the type and extent of services furnished to particular parcels of property within the District. The judgment of the district court is reversed insofar as it determines that the District must comply with the provisions of section 32-1-207(2), 13 C.R.S. (1984 Supp.), and the cause is remanded to the district court with instructions to affirm the decision of the BAA.
