A state court denied D.R. Horton’s request for partial summary judgment against Rockwall County on Apr. 6, allowing a trial to proceed over who is responsible for paying infrastructure costs related to new suburban development in North Texas.
The case has broader implications for how fast-growing counties handle the expenses tied to new housing projects. As areas like Rockwall experience rapid population growth, local governments face pressure to expand roads, utilities, and public services without shifting the financial burden onto existing residents.
The dispute centers on River Rock Trails, a planned community located in an unincorporated area of Rockwall County. D.R. Horton and DMDS Land Company are challenging the county’s requirement that developers pay for certain infrastructure improvements as part of the project’s first phase—an 85-acre section with plans for 418 homes within a larger development area exceeding 1,800 acres.
At issue is whether the developer fees imposed by the county are “roughly proportionate” to the impact of the project. D.R. Horton argues that these fees exceed what is reasonable under Texas law, while county officials maintain they reflect actual costs associated with supporting new growth.
In its recent order, the court upheld Rockwall County’s authority to impose such fees as long as they comply with state code and directed both parties into mediation before setting a trial schedule if negotiations do not succeed. According to local officials quoted in media reports, this decision affirms their ability to require developers—not current residents—to bear much of the cost of expanding infrastructure needed by large-scale developments.
