Rockwall County to seek new outer loop alignments after suspension of engineering work

Rockwall County commissioners and staff told the Rockwall County Road Consortium they will pursue additional alignments for the regional outer loop and have paused county-funded engineering work while they study options and consult the North Central Texas Council of Governments.

Commissioner Lichtine said the county removed two related items from a Jan. 14 commissioners court agenda after the council of governments' general counsel asked the court not to consider them, and the court instead voted to suspend the county's engineering contract for the outer loop for up to 90 days pursuant to the contract's terms. "It was a very good move," Lichtine said of the suspension, which he said preserved the county's ability to align its objectives with the consultant's work.

The suspension gives the county time to develop and submit alternate southern alignments to the Regional Transportation Council for traffic projections and viability analysis, Michael Morris, director of the Regional Transportation Council, told the consortium. Morris told county leaders the RTC would consider alternate routes, and that, "other than those connection points, the alignment is largely up to Rockwall County," provided the alternatives are viable. He also told the county the RTC could run traffic projections on up to six additional alternates if the county presents them.

Why it matters: the outer loop is a regional corridor that would shift traffic patterns across multiple counties and has drawn concentrated public concern in Rockwall County's Precinct 3. Commissioners said they want an outcome that minimizes residential displacement, noise and linear apartment development along any new highway alignment.

County next steps described to the consortium include developing new southern alignments in coordination with county staff and consultants, returning alternatives to the RTC/NCTCOG for modeling and feasibility, and engaging the public across the county on the resulting options. Commissioner Stacy said the routes north of State Highway 276 are largely finalized and the principal work remaining is south of 276.

Consortium members and commissioners also discussed mitigation measures the county will seek to limit visual and noise impacts and to discourage strip development along new alignments. Commissioners noted one option under consideration is shifting portions of the southern alignment into neighboring Hunt County; Rockwall officials said they have discussed that concept with Hunt County officials and that any shift would require the neighboring counties' agreement.

County funding and contract status were raised by consortium members. Presenters said the county's existing engineering contract for the corridor is approximately $8.8 million and that about 60% of that contract had been expended before the suspension; exact remaining costs to re-scope or extend the contract were not specified at the meeting. Presenters also said the council of governments indicated it could take up the project if Rockwall County declined to continue, because the RTC has authority and regional funding mechanisms.

Commissioners asked that technical traffic modeling be provided at the link level for proposed alternatives so local leaders can see how each option would affect specific roads such as State Highway 205, SH-276 and I-30. Consortium staff and RTC representatives told the group they already model county- and link-level effects for 2050 scenarios and can run additional scenarios for alternatives the county develops.

The consortium meeting closed the outer loop discussion by directing county staff and commissioners to work with their consultants to lay out additional southern alignments, return to NCTCOG/RTC for viability analysis, and plan a public engagement process before the commissioners court makes further final decisions.
