OPINION
Appellant, Syed Ahmed, brought an inverse condemnation lawsuit against appel-lee, Metropolitan Transit Authority (“METRO”), for damages allegedly caused by METRO’S improvements on a drainage ditch. The trial court granted METRO’S plea to the jurisdiction and dismissed the case. In his sole issue, appellant contends that the trial court erred in granting the plea to the jurisdiction because it had subject matter jurisdiction over his inverse condemnation claim. We reverse and remand.
BACKGROUND
The property made the basis of this inverse condemnation case is a .68756-acre tract of undeveloped land in northwest *31 Houston (the “Property”). The Property is a portion of a larger tract of land that was originally owned by the Sommermeyer family. On August 30, 1955, the Sommer-meyer family conveyed a 30-foot-wide easement to the Harris County Flood Control District (the “District”) for drainage and flood control on a drainage ditch extending across the Property and other properties in northwest Houston. 1 Only a 15-foot-wide portion of the Property is included within the 30-foot easement. On April 19, 1979, the District obtained a 100-foo1>-wide easement covering portions of properties traversed by the 30-foot easement, including the Property, for drainage and flood control on the drainage ditch and unit E117-07-00. Only a 50-foot-wide portion of the Property is included within the 100-foot easement. The two easements are used to maintain the drainage ditch and unit El17-07-00.
In 1991, METRO began developing plans to widen Gessner Road from Tanner Road to Hempstead Highway (the “Gessner Project”), requiring that the drainage ditch, traversing the Property and adjacent properties, be expanded. The District decided that unit El 17-07-00 would receive the increased storm-water runoff expected to result from the Gess-ner Project and contracted with METRO to finance and oversee the expansion and improvements on the drainage ditch. METRO contracted with a third party to perform the drainage work. In 2005, Harris County foreclosed the Property for nonpayment of property taxes and sold it to appellant in an auction in 2006. Three months after appellant acquired the Property, METRO’S subcontractors entered the Property and adjacent tracts of land to begin work on the drainage ditch. They constructed a new detention pond, improved the drainage ditch, and performed other drainage-related work. During the improvements, appellant notified METRO on a number of occasions that it was trespassing on the Property. METRO continued the improvements and completed the drainage work in January 2007.
Thereafter, appellant filed suit against METRO alleging inverse condemnation under the Texas Constitution. Specifically, appellant claimed that METRO, acting outside the scope of the easements, condemned the Property by expanding the drainage ditch. METRO filed a plea to the jurisdiction contending that the trial court lacked subject matter jurisdiction over appellant’s inverse condemnation claim. METRO alleged that because it acted within the scope of the two easements, appellant could not establish an intentional taking. The trial court granted METRO’S plea to the jurisdiction, and appellant filed the instant appeal. In his sole issue, appellant argues that the trial court erred in dismissing his lawsuit because it had jurisdiction over his inverse condemnation claim.
STANDARD OF REVIEW
A plea to the jurisdiction challenges the court’s subject matter jurisdiction.
Bland Indep. Sch. Dist. v. Blue,
When a plea to the jurisdiction challenges the sufficiency of the plaintiffs pleadings, we determine if the pleader has alleged facts that affirmatively demonstrate the court’s jurisdiction to hear the cause.
Miranda,
When a plea to the jurisdiction challenges the existence of jurisdictional facts, as in the instant case, we consider relevant evidence submitted by the parties when necessary to resolve the jurisdictional issues raised.
Miranda,
ANALYSIS
Article I, section 17 of the Texas Constitution waives immunity from suit and liability in inverse condemnation cases and authorizes compensation for such constitutional taking.
See
Tex. Const, art. I, § 17;
Gen. Servs. Comm’n v. Little-Tex Insulation Co., Inc.,
METRO’S plea to the jurisdiction challenges the existence of jurisdictional facts, not the sufficiency of appellant’s pleadings. 2 In its plea, METRO disputes the facts underlying appellant’s inverse condemnation claim; specifically, METRO disputes that: (1) METRO engaged in an intentional act; and (2) the intentional act resulted in a taking of the Property. METRO submitted evidence showing that: (1) the drainage work was authorized by statute; (2) a portion of the drainage work *33 was supported by easement rights; (3) the drainage work did not result in an entire taking of appellant’s property; and (4) METRO did not act with the requisite intent. In response, appellant filed an affidavit contending that METRO exceeded the scope of the 30-foot easement and was not authorized to perform the drainage work.
The evidence before us raises a fact issue as to whether the drainage work was supported by easement rights and whether METRO acted within the scope of the easement. These issues ultimately determine whether appellant will succeed on the merits of his claim and recover damages. Relying on
Miranda,
METRO invites us to review the evidence and resolve these fact issues in METRO’S favor. We decline METRO’S invitation.
Miranda
allows dismissal on a plea to the jurisdiction only when the jurisdictional evidence is undisputed and fails to raise a fact issue.
See Miranda,
METRO also relies on a line of cases to support its proposition that a plea to the jurisdiction can be used to dismiss a case on the merits.
See City of Del Rio v. Felton,
No. 04-06-00091-CV,
Taking as true all evidence favorable to the nonmovant, we conclude that there is disputed jurisdictional evidence raising a fact issue as to whether METRO engaged in an intentional taking under article I, invoking subject matter jurisdiction over appellant’s inverse condemnation claim. We sustain appellant’s sole issue on ap *34 peal. We reverse the trial court’s judgment and remand for further proceedings.
