OPINION
Justice.
Richard Schecter appeals an order granting pleas to the jurisdiction filed by Wildwood Developers, L.L.C. (Wildwood), the City of El Paso (the City), and the City Plan Commission and its Commissioners (the Commission). We affirm.
FACTUAL SUMMARY
Schecter’s home is located in west El Paso within 300 feet of Wildwood Arroyo which is owned by Wildwood Developers. In November 2004, the Commission approved the subdivision plat filed by Wild-wood for development of the arroyo and the city engineer approved the subdivision improvement plans. Before development began, Schecter filed suit against the City and the Commission in an effort to halt the project. He specifically sought a declaratory judgment that (1) the Commission’s approval of the subdivision violates Section 19.16.050 of the Municipal Code (requiring that arroyos be preserved in their natural state); (2) the subdivision application is void because it does not meet the City’s design criteria; and (3) the Commission’s approval of the subdivision application is void because it was based on Wildwood’s fraudulent and false statements. Schecter also sought mandamus and injunctive relief.
Wildwood intervened and filed a plea to the jurisdiction, complaining that Schecter lacked standing to maintain his suit. The City and the Commission filed a plea to the jurisdiction based upon the same argument. They also claimed sovereign immunity. Following a hearing, the trial court specifically found that Schecter lacked standing and granted the pleas. Schecter timely filed a notice of appeal. We grant *120 ed emergency relief to prohibit any grading or alteration of the arroyo, but we lifted the stay when Schecter failed to post the required security. Development of the arroyo began shortly after the stay was lifted.
PLEA TO THE JURISDICTION
In Issue One, Schecter challenges the trial court’s conclusion that he lacks standing to seek a declaratory judgment. He has not raised any issue regarding the trial court’s determination that he lacks standing to seek injunctive or mandamus relief. Consequently, those aspects of the trial court’s ruling are not before us.
Mootness
The City, the Commission, and Wild-wood all contend that the appeal is moot because development of the Arroyo has been proceeding since the stay order was lifted. For a plaintiff to have standing, a controversy must exist between the parties at every stage of the legal proceedings, including the appeal.
Williams v. Lara,
By his suit, Schecter sought to halt the planned alteration of the arroyo’s natural condition because he it would purportedly cause his property value to decrease. Although he could have maintained the status quo by posting the required security, he failed to do so and the development has progressed during the pendency of his appeal. While the parties disagree as to the extent of the development, it is undisputed that the natural condition of the arroyo has been significantly altered through grading and removal of all vegetation. A judicial declaration that the Commission’s approval of the subdivision violated the Municipal Code would not resolve the controversy between the parties because the arroyo has already been altered from its natural state.
Schecter nevertheless maintains that the appeal is not moot because his suit is not limited to preventing changes to the arroyo’s natural state. In support of this argument, he reminds us that he also sought a judicial declaration that Wild-wood’s subdivision application is void because it does not meet the City’s design criteria and that the Commission’s approval of the application is void because it was based on fraudulent and false statements. Because there is nothing in the record to indicate that the subdivision has been completed to the point that these two issues are moot, we will address the merits of the trial court’s ruling as it pertains to these issues.
Standard of Review
A plea to the jurisdiction contests a trial court’s subject matter jurisdiction.
Bland Independent School District v. Blue,
Standing
Standing is a component of subject matter jurisdiction and is properly raised by a plea to the jurisdiction.
Texas Association of Business v. Texas Air Control Board,
The purpose of the Uniform Declaratory Judgment Act is to settle and afford relief from uncertainty and insecurity with respect to rights, status, and other legal relations. Tex.Civ.PRAC. & Rem.Code AnN. § 37.002 (Vernon 1997). The Act does not confer jurisdiction on the trial court; it offers the remedy of a declaratory judgment for a cause of action already within the court’s jurisdiction.
State v. Morales,
A person interested under a deed, will, written contract, or other writings constituting a contract or whose rights, status, or other legal relations are affected by a statute, municipal ordinance, contract, or franchise may have determined any question of construction or validity arising under the instrument, statute, ordinance, contract, or franchise and obtain a declaration of rights, status, or other legal relations thereunder.
Tex.Civ.PraC. & Rem.Code Ann. § 37.004(a).
Schechter sought a declaratory judgment that (1) the subdivision applica *122 tion is void because it does not meet the City’s design criteria; and (2) the Commission’s approval of the subdivision application is void because it was based on Wild-wood Developers’ fraudulent and false statements. Neither of these claims is based upon or related to Schecter’s rights, status, or legal relationship under a statute, municipal ordinance, contract or franchise. Consequently, he lacks standing to seek these declarations. We overrule Issue One. Because the trial court correctly granted the pleas on that basis, we need not address his second issue pertaining to sovereign immunity. We affirm the trial court’s order dismissing Schecter’s suit.
