Appellants, Friends of Mount Aventine, Inc., (FOMA), Alexander M. Winter, Bonnie Bick, John J. Myles, Sr., and Harold Von Braunhut, appeal from an order of the Circuit Court for Anne Arundel County granting appellees’ motion to dismiss appellants’ complaint. On appeal, appellants ask but two questions, which we have restated as follows:
I. Did the trial court err in dismissing plaintiff, Friends of Mount Aventine, Inc., for lack of standing?
*206II. Did the trial court err in dismissing appellants’ complaint on the ground that it was not ripe for adjudication?
For the reasons discussed fully below, we shall answer both questions in the negative and affirm the judgment of the circuit court. .
Facts
This dispute centers on a parcel of real estate in Charles County known as Chapman’s Landing, owned by Banyan Management Corporation (“Banyan”). Chapman’s Landing extends for approximately two miles along the shoreline of the Potomac River, and inland for approximately 1,000 feet.
In 1992, as a result of a comprehensive rezoning of Charles County, Chapman’s Landing was designated as low density residential.1 In March 1992, the County Commissioners of Charles County (the “County”) amended the County’s Water and Sewerage Plan. Two amendments of the Plan affected Chapman’s Landing.2 The first awarded Chapman’s Landing an S-5 sewer service priority, making an extension of sewer service possible within six to ten years. The second extended the County’s Mattawoman Sewer Service Area.3 Pursuant to Md.Code (1982, 1993 Repl.Vol.), § 9-507 of the Environment Article, the County submitted both amendments to the Maryland Department of the Environment (“MDE”) for approval.
MDE first referred the amendments to the Maryland Office of Planning (“MOP”), to determine whether they were consistent with the County’s comprehensive water and sewerage plan. After receiving further information, MOP approved the amendments, as did MDE. Appellants then filed a complaint in the Circuit Court for Anne Arundel County, seeking a *207declaratory judgment and to enjoin the amendments. Appellees responded with a motion to dismiss. After dismissing FOMA and Winter from the suit for lack of standing, Judge Goudy granted appellees’ motion to dismiss because appellants’ claim was not ripe for adjudication. This appeal followed.
Discussion
I.
A.
We begin by noting that we are not obligated to determine whether FOMA had standing under the Maryland Environmental Standing Act (MESA), Md.Code (1974, 1989 Repl.Vol.) § 1-501 et seq. of the Natural Resources Article, because the standing of appellants Myles and Von Braunhut has not been challenged. In Montgomery County v. Board of Supervisors of Elections, 311 Md. 512, 516 n. 3, 536 A.2d 641 (1988), the Court of Appeals noted that, as one of the plaintiffs had standing to bring the suit, it was not necessary for the Court to reach the merits of the circuit court’s ruling dismissing another. See Sugarloaf Citizens Ass’n v. Northeast Maryland Waste Disposal Authority, 323 Md. 641, 650 n. 6, 594 A.2d 1115 (1991); State’s Attorney v. Mayor & City Council of Baltimore, 274 Md. 597, 602, 337 A.2d 92 (1975).
B.
While we need not reach the merits of FOMA’s standing claim, we nonetheless do so and hold that the trial court did not err in concluding that MESA did not confer standing on FOMA.4
MESA § 1-503 provides in relevant part that
“[a]ny ... person, regardless of whether he possesses a special interest different from that possessed generally by *208the residents of Maryland, or whether substantial personal or property damage to him is threatened[,] ... may bring and maintain an action for mandamus or equitable relief, including declaratory relief against any officer or agency of the State ... for failure ... to perform a nondiscretionary ministerial ctóyimposed upon them under an environmental statute, ordinance, rule, regulation, or order[.]
According to appellants, MDE and MOP had a “duty under the Environmental Article to ensure consistency between the county’s water and sewerage plan and its comprehensive planning (including critical area program).” Accordingly, appellants conclude that MESA confers standing on FOMA. We disagree.
We begin by noting that appellants place undue emphasis on Maryland Waste Coalition v. Maryland Dep’t of the Environment, 84 Md.App. 544, 581 A.2d 60 (1990). We remanded Maryland Waste to the circuit court for further proceedings. Nevertheless, we were reversed by the Court of Appeals in Medical Waste Assocs. v. Maryland Waste Coalition, Inc., 327 Md. 596, 622, 612 A.2d 241 (1992). In Medical Waste, the Court of Appeals looked to both the language and legislative history of MESA and “h[e]ld that MESA does not ordinarily grant organizations ... standing to participate in judicial review of an administrative decision.”
Consequently, we must ascertain whether MDE’s approval of the proposed amendments to the water and sewerage plan constituted a discretionary administrative decision. In Holmes v. Maryland Reclamation Assocs., Inc., 90 Md.App. 120, 150-151, 600 A.2d 864, cert. dismissed, 328 Md. 229, 614 A2d 78 (1992), we emphasized the discretionary nature of MDE’s review of proposed amendments under Md.Code (1982, 1993 Repl.Vol.), § 9-507(a) of the Environment Article,5 and *209said that “MDE may reject a county’s proposed plan or plan revision, or it may ‘[mjodify or take other appropriate action on the proposal’ ” (quoting § 9-507(a)). In Holmes, we took note of “MDE’s strong control over county plans, including its ability to modify or veto plans or amendments of which it does not approve.”6 Id. at 151, 600 A.2d 864. (Emphasis added.)
Consequently, we hold that where, as here, an agency is free to reject, approve, modify, or take any “appropriate action” with respect to proposed amendments to a county waste and sewerage plan, that agency is making a discretionary administrative decision. Thus, MESA is inapplicable and the trial court did not err in dismissing FOMA for lack of standing.
II.
Appellants also contend that Judge Goudy erred in dismissing their complaint for lack of ripeness. Both this court and the Court of Appeals have held that “the existence of a justiciable controversy is an absolute prerequisite to the maintenance of a declaratory judgment action.” Hatt v. Anderson, 297 Md. 42, 45, 464 A.2d 1076 (1983); Anne Arundel County v. Ebersberger, 62 Md.App. 360, 367-368, 489 A.2d 96 (1985). In determining whether justiciability exists, “ ‘ripeness’ ... may be involved.” Ebersberger, supra at 368, 489 A.2d 96. “Generally, an action for declaratory relief lacks ripeness if it involves a request that the court declare the rights of parties upon a state of facts which has not yet arisen, [or] upon a matter which is future, contingent and uncertain.” *210 Boyds Civic Ass’n v. Montgomery County Council, 309 Md. 683, 690, 526 A.2d 598 (1987). In reviewing Judge Goudy’s dismissal for lack of a justiciable controversy, “we limit our consideration ... to allegations of fact and the inferences deducible from them” and “[i]f any material facts alleged in [appellants’] complaint tend to support [appellants’] right to recover, the order to dismiss must be reversed.” Lee v. Denro, Inc., 91 Md.App. 822, 828, 605 A.2d 1017 (1992).
A.
As appellants, see it, this matter is ripe for adjudication because “the Chapman’s Landing Development is beyond the stage of speculation or remoteness.” In support of their position appellants urge—without citation to any controlling authority—that “Chapman’s Landing is a specific proposal by a specific developer for a specific area.” Looking for a legal thread upon which to hang appellants’ conclusory statement, we turn to Gregory v. Board of County Comm’rs, 89 Md.App. 635, 642, 599 A.2d 469 (1991). In Gregory, appellants similarly asserted that “the impact of [a county] Board’s action ‘was very specific and applied to [specific] properties’ ” and thus constituted a “piecemeal zoning action” ripe for appeal under Md.Code (1957, 1988 Repl.Vol.), Art. 66B § 4.08(a).7 Id. In the case at hand, unlike in Gregory, appellants seek declaratory relief. As a result, Gregory is of no help to appellants and their contention must fail.8
B.
In a similar vein, appellants contend that the challenged amendments are “an essential prerequisite to the entire shore*211line development, which cannot occur without sewerage service.” We fail to grasp appellants’ point. In the case at hand, the S-5 water and sewerage service priority applies to “[a]reas which are located within a central service area but are not yet approved for central service [and thus sjervice is possible within 6 to 10 years, but not guaranteed. ” We point out to appellants that we said in Ebersberger, supra 62 Md.App. at 371, 489 A.2d 96, that such amendments “do[ ] not require the [county to permit residential development at a certain level but] merely authorize[] such [development].” (Emphasis in original).
In the instant case, designating Chapman’s Landing as S-5 merely means that water and sewerage service are a future possibility. While we agree with appellants that the amendments may “enable the project [appellants] oppose,” the challenged amendments do not ensure that the Chapman’s Landing project will ensue. Moreover, appellants concede that, in order to proceed with the Chapman’s Landing project, it would be necessary for appellees to clear the significant procedural hurdle of securing growth allocation. As Judge Goudy put it, “these land use [amendments] do not necessarily lead to residential development.” We agree. There was no error.
C.
Finally, appellants contend that Boyds Civic Ass’n v. Montgomery County Council, 309 Md. 683, 526 A.2d 598 (1987), is dispositive. In Boyds, property owners filed a complaint against the Montgomery County Planning Board after the Board had amended the Boyds Master Plan to designate certain areas as a Mineral Resource Recovery Zone, permitting stone quarrying. The Court of Appeals said in Boyds that, where “[t]he threat of ... potential rezoning ... hangs like a pall of smoke over ... [neighboring] properties ‘within sight and sound’ of ... land sought to be quarried[,] a justiciable controversy exists.... ” Id. at 700, 526 A.2d 598.
*212Nevertheless, Boyds is distinguishable in several respects. First, the amendments at issue here, as we have said, were “clearly ‘designed to affect local and regional needs and all property owners within the planning area. ’ ” Gregory, supra 89 Md.App. at 642, 599 A.2d 469 (emphasis added). Moreover, the rezoning of Chapman’s Landing is not before us, and appellants concede that appellees “cannot develop [Chapman’s Landing] to a greater intensity than one home per twenty acres without clearing the procedural hurdle of securing growth allocation.”9
Appellants also contend that “construction pursuant to the amendments challenged here appears less contingent and uncertain than quarrying in Boyds ... [both because] amendment 89A-C resulted in an ‘action plan to be implemented as rapidly as possible’ ” and “[t]he plan provides that the county and the developer should make ‘[e]very effort ... to expedite water and sewer projects.’ ” We are not persuaded. As we noted in JMC Constr. Corp. v. Montgomery County:
Such land use planning documents [as a master plan] represent only a basic scheme generally outlining planning and zoning objectives in an extensive area, and are in no sense a final plan; they are continually subject to modification in the light of actual land use development and serve as a guide rather than a strait jacket.
54 Md.App. 1, 12, 456 A.2d 931 (1983) (quoting Montgomery County v. Woodward & Lothrop, 280 Md. 686, 703-704, 376 A.2d 483 (1977)). In Boyds, the Court of Appeals determined that, while the adjacent property owners contesting the procedures leading to the designation of land adjacent to them on the Boyds Master Plan as suitable for a Mineral Discovery Zone “presented an issue cognizable in a declaratory judgment action[,] ... the adoption of an amendment to the master plan *213... [was] not a contested case within the meaning of the Administrative Procedure Act----”
In contrast to Boyds, the amendments challenged here were not “initiated, approved, and adopted in furtherance of an actual, pending application to amend the local zoning map.” Boyds, supra 309 Md. at 697, 526 A.2d 598. Rather, “the challenged [amendments] could have no injurious effect upon the plaintiffs until the prospect of [their] implementation,” through approval of growth allocation10 of the subject property, became “ ‘substantially more certain.’ ” Id. (quoting Ebersberger, supra 62 Md.App. at 371, 489 A.2d at 96).
While appellants correctly note that the Boyds Court looked to Maryland Code (1974), § 3-402 of the Cts. & Jud.Proc. Article for the proposition that “the Maryland version of the Uniform Declaratory Judgments Act ... is remedial ... [and] shall be liberally construed and administered,” Boyds, supra at 688, 526 A.2d 598, the Boyds Court also said that “the existence or nonexistence of ripeness is a question of degree” and a court must be “satisfied that the ‘ripening seeds’ of an actual controversy exist....” Id. at 691, 526 A.2d 598 (emphasis added).
We hold that Judge Goudy did not err in concluding that appellants had planted no “ ‘ripening seeds’ of an actual controversy.’ ”
