The County Responded
Here's What They Said — And What They Didn't
On April 29, 2026, the Hays County Road Improvements Program published an official response to the community's concerns about the Darden Hill Road expansion. Below is our analysis of each response — quoting the county directly and providing the context their answers leave out.

Our Eight Demands — Their Responses
What the county said, and what it means
Publish Current Traffic Data
The county said
“The schematic design process, that is just now starting, for the Extension project will include conducting a traffic study from Sawyer Ranch Road to RM 150 near Woods Loop (collecting traffic counts and analyzing traffic data to determine the level of service that is projected with the improvements).”
Our analysis
The county confirmed it will conduct a traffic study — validating our demand. But the most recent count (1,600 vehicles per day from 2018 data) has never been updated or acknowledged in their project justification. The county advanced a four‑lane design for years without current traffic data. We asked them to publish it. They agreed, effectively conceding the data gap existed.
Traffic Noise Study
The county said
“While federal noise regulations and formal noise analyses apply specifically to projects that receive federal funding, noise considerations are still part of the County's broader, context‑sensitive design approach for locally funded projects. Even without a federal requirement, the County evaluates reasonable measures that can help manage roadway noise, such as pavement types that reduce tire noise.”
Our analysis
The county will not conduct a formal noise study. They acknowledge noise is “an important concern” but say federal standards don't apply because this is locally funded. TxDOT conducted a full noise analysis for the connecting RM 1826 corridor — a comparable project — and found noise levels exceeding the 67 dB(A) federal threshold. The county offers “pavement types” instead of data. Residents still have no projected noise impact numbers for their homes.
Safe Routes to School Assessment
The county said
“The programs referenced are different federally funded programs. This project is locally funded, and we do not anticipate submitting an application for federal funding. We have evaluated that plans provide ‘safe routes to school.’”
Our analysis
The county says SRTS doesn't apply because the project isn't federally funded. But SRTS assessments are a best practice, not a funding requirement. The county claims to have “evaluated” safe routes — but has not published any such assessment. Three DSISD campuses sit on or adjacent to this corridor. The community is asking for transparency: show us the evaluation.
Reduce to Two Lanes (Super Two)
The county said
“Super 2 roadway configurations are utilized on roads classified as highways and are used on stretches of highway between smaller rural towns, along freight routes where passing opportunities are needed, and in transition zones.”
Also:
“While the long‑term plan identifies four lanes, the County may consider phasing improvements. As the design of the Extension project advances, an interim two‑lane configuration may be considered, with the ability to add additional lanes in the future if and when traffic conditions warrant it.”
Our analysis
Two significant points here. First, the county dismisses Super Two as only for “highways between rural towns” — but TxDOT's own Roadway Design Manual includes Super 2 design standards for exactly this type of corridor. Second, and more importantly: the county acknowledges that an interim two‑lane configuration may be considered. This is a notable shift. The community should hold the county to this opening.
Set the Speed Limit at 35 mph
The county said
“The current posted speed on Darden Hill Road is 40 mph, and there are no plans to increase it. A higher design speed is sometimes utilized for safety purposes, but it does not determine the final speed that traffic will be allowed to travel on the road.”
Our analysis
This contradicts the county's own 2023 open house materials, which specified a “45 mph speed limit,” and the February 2026 community meeting summary, which reported a 45 mph speed limit. The county is now drawing a distinction between “design speed” and “posted speed.” If 40 mph is truly the intended posted speed, the county should formalize this commitment in writing. Even at 40 mph, the community's request for 35 mph — matching Sawyer Ranch Road — remains justified given three adjacent school campuses.
Truck Weight Limit
The county said
“The County recognizes that large truck traffic is a concern and will evaluate potential options as design progresses. Because Darden Hill Road connects to RM 150 and RM 1826, both of which cannot restrict truck traffic, any restrictions on Darden Hill Road would rely on enforcement and would be difficult to implement effectively.”
Our analysis
The county acknowledges trucks are a problem but says restrictions would be “difficult to implement.” This is an admission that the four‑lane design will carry heavy truck traffic through a residential community with three schools — exactly what the community has warned about.
Remove the Planned Extension
The county said
“Darden Hill Road is planned to ultimately function as a four‑lane divided roadway so it can tie safely and consistently into RM 150 improvements and the future Dripping Springs Southwest Connection, both of which are planned as four‑lane facilities. Maintaining a consistent roadway configuration along a corridor helps reduce abrupt transitions that can disrupt traffic flow and increase crash risk.”
Our analysis
The county justifies the extension by pointing to other planned four‑lane roads it would connect to — the same circular logic we have pointed out, repeatedly. Each project justifies the next. The Dripping Springs Southwest Connection — the road the county cites as justification for matching Darden Hill to four lanes — is itself unfunded beyond a 20% conceptual study. The county's own documents state that “funding for additional environmental studies, schematic design, and construction has not been identified” and that the next phases could take “3 to 7+ years.” The county is building a four‑lane highway now to match a road that may not exist for a decade. The community rejected this bypass concept in 2015 with a 322‑signature petition. The county is building the same connectivity under a different name.
Re‑engage the Community
The county said
“The County has conducted multiple rounds of public engagement since the 2017 Character Plan. This includes the 2021 Transportation Plan Update, which included 2,250+ site visitors, 750+ comments, and meetings with stakeholder groups across the County.”
Our analysis
The county cites the 2021 Transportation Plan Update as evidence of community engagement. But this was a countywide plan — not a Darden Hill‑specific process comparable to the three‑year, 530+ attendee Character Plan that resulted in a two‑lane recommendation. The shift from two lanes to four happened without a comparable community process focused on this corridor.

What changed between the lines
Growth numbers quietly dropped
The county said
“...the Texas Demographic Center anticipating 68% population growth in the County by 2050”
Our analysis
The county's own 2023 open house slides cited “267% anticipated population growth by 2045” (sourced to CAMPO). The response now cites 68% by 2050 from the Texas Demographic Center — a dramatically lower figure. The county quietly replaced its own headline growth justification. The trend is consistent across data sources: the school district's own March 2026 demographic study (prepared by Population and Survey Analysts) shows DSISD enrollment growth decelerating from 9.9% annually to 1.1% — even as the county continues to cite long‑range projections to justify a four‑lane highway.
Certificates of Obligation
The county said
“The 2024 bond was invalidated due to a procedural issue, not the substance of the projects or the voter approval.”
Our analysis
This is technically accurate — the judge voided the bond for violating the Texas Open Meetings Act, not because voters opposed the projects. But the legal consequence is the same: there has been no valid voter authorization for these projects. The county then used Certificates of Obligation — debt that does not require voter approval — to advance them regardless.
The county has responded. Now it's your turn.
