Consultants urge Rockwall County to update thoroughfare plan to reflect rapid growth

Friese Nichols consultants outlined why Rockwall County should update its master thoroughfare plan during an Aug. 27 workshop, telling the Commissioners Court that population growth, regional planning changes and recent county policy shifts make an update timely.

Connor Roberts, lead presenter for Friese Nichols, said the firm prepared Rockwall County’s 2019 Thoroughfare Plan and recommended routine five‑year reviews and more substantive updates every five to ten years. Roberts noted the county’s population has increased by about 30,000 since 2019 and said an updated map, travel modeling and coordinated municipal input would give the court current technical guidance when it considers development applications.

“Keeping pace with changing population and demographics is always front of mind,” Roberts said, describing the update as a way to maintain continuity with municipal and regional plans and to improve coordination with the North Central Texas Council of Governments (NCTCOG) and adjacent counties.

Eddie Haas, Friese Nichols’ transportation planning manager, emphasized safety and fiscal stewardship as central goals. Haas showed crash‑index data from neighboring counties and urged that arterial corridors be preserved early to avoid higher future costs for right‑of‑way acquisition. He described the plan as a “living document” that sets high‑level corridors rather than final alignments or property lines.

The consultants walked the court through technical approaches and budgets. Options included a lower‑cost engagement using existing COG data and limited modeling (roughly in the low hundreds of thousands of dollars) and a full model and public‑engagement approach that would be more expensive, with the largest scopes requiring a full regional travel‑demand model update and scenario testing.

Friese Nichols also discussed administrative options for how the county might apportion road‑building costs. The firm described a “service unit” approach used in some cities — estimating thoroughfare implementation costs, converting those costs to a per‑service‑unit number, and comparing a development’s system impact to that unit cost so developers pay a proportionate share. The consultants cautioned that “state law doesn’t allow for that right now” at the county level and advised seeking county attorney guidance on defensible approaches; they said they have implemented capital‑recovery approaches for cities and city ETJs but not for counties under current state law.

The consultant team recommended robust stakeholder outreach — steering committees, school districts, developers, TxDOT and NCTCOG participation, online surveys and town halls — and suggested a GIS dashboard to make plan maps and programmed projects easy to explore.

Why it matters: commissioners repeatedly said they want a current technical basis for right‑of‑way dedications, impact apportionment and bonding decisions. The court discussed using bond proceeds to pay for higher‑quality planning and whether to preserve corridor footprints ahead of intensive development in the county’s ETJs.

The presentation concluded with the consultants offering to return with a scope and cost options if the court wants to proceed.

Ending: Commissioners used the presentation as the starting point for a later discussion about forming a working committee to scope the update and to consider funding in an upcoming bond issuance.
