Hays County is building a highway through our neighborhood.
The county's plan puts 45 mph freight and commuter bypass traffic directly alongside new elementary school bicycle routes on Darden Hill Road. That is not a design conflict that can be engineered away. It is a fundamental choice: build for the trucks, or build for the children. The county chose the trucks.
Engineering is 30% complete. The window to change this plan is closing. We need your support.
The County's Plan
They asked us. We answered. They ignored us.
Hays County's Improve 150 program calls for widening Darden Hill Road from a rural two‑lane road to a four‑lane divided highway with a median, shoulders, bike lanes, and a 45 mph speed limit. The county collected community input, documented our opposition, and advanced a plan that contradicts it.
From the county's own planning documents
The 2013 Hays County Transportation Plan recommended only the addition of a center turn lane to Darden Hill Road — not a four‑lane expansion.
The 2017 RM 150 West Character Plan, prepared by K Friese & Associates and accepted by the Commissioners Court on October 10, 2017, specified two‑lane configurations throughout the corridor — two 11‑ft lanes with a 14‑ft center turn lane in community zones, and two 12‑ft lanes with shoulders in rural zones. The county‑appointed Citizens Advisory Panel recommended roundabouts at major intersections specifically to maintain rural character and reduce property impact.
"Keep it just like it is — 2 lane undeveloped is rural, and that's the attraction."
— Recurring community sentiment documented in the Character Plan process
The current four‑lane proposal substantially exceeds the scope of what the county's own studies identified as necessary, and contradicts the community input the county collected and documented.

The project phases
Darden Hill Improvements
RM 1826 → Sawyer Ranch Rd
Four-lane divided roadway with median, shoulders, and intersection improvements.
Darden Hill Extension — Our Concern
Sawyer Ranch Roundabout → RM 150
Four-lane widening through our community, extending the road to FM 150 at Woods Loop.
A planned future extension would complete the corridor, creating a continuous high‑speed route from RM 1826 through to RM 12 via FM 150. The county describes this as "an improved connection" — but what it connects is 45 mph freight and commuter traffic to a road that runs directly past our homes and our children's schools.
The county's plan simultaneously builds bike paths for elementary schoolers and a 45 mph four‑lane arterial for heavy traffic — on the same road. That is not an engineering tradeoff. It is a contradiction.
The county's stated project goals
- “Improve safety, mobility, and connectivity between RM 1826 and RM 12”
- “Design improvements that will enhance the transportation experience in the area”
- “Coordinate with property owners and the community to share information and determine feasible solutions”
We share the first two goals. We are here to ensure the county follows through on the third.

Why This Matters
What this plan does to our community
Children on bicycles. Trucks at 45 mph. Same road.
The county's own design calls for bike paths alongside a 45 mph four‑lane arterial — directly adjacent to new Dripping Springs ISD school campuses. These are the deadliest road configurations for pedestrians in the United States.
fatality risk for a pedestrian struck at 40 mph
fatality risk for a pedestrian struck at 20 mph
Tefft, B.C., "Impact Speed and a Pedestrian's Risk of Severe Injury or Death," AAA Foundation for Traffic Safety, 2011. Risk is substantially higher for children and elderly. NHTSA data shows the majority of U.S. pedestrian fatalities occur on arterial roads (FARS, 2023). Research published in Accident Analysis & Prevention identifies four‑lane roads near schools as a significant predictor of child pedestrian injuries (Rothman et al., 2015).
A Safe Routes to School assessment is an established federal best practice for road projects near schools — and to our knowledge, one has never been conducted for the Darden Hill expansion. Three Dripping Springs ISD campuses sit on or adjacent to Darden Hill Road — Cypress Springs Elementary (11091 Darden Hill Rd, 660+ students), the planned new high school site directly adjacent to it, and Sycamore Springs Middle School about two miles north on Sawyer Ranch Road. All three served by the road the county wants to turn into a 45 mph four‑lane arterial. The county has applied SRTS principles to other Hays County projects but not to the one with arguably the most direct school impact.
Our homes are our largest investments
We purchased homes on a two‑lane rural road in the Hill Country. A four‑lane, 45 mph highway corridor will permanently degrade the safety, quiet, and property values that define this community. We did not buy homes on a highway. The county should not build one through our front yards.
Growth is not an excuse for a highway
The county cites population growth and Cypress Springs Elementary (660+ students, opened 2021) as justification for four lanes. But growth was already anticipated when the county paid K Friese & Associates — professional transportation engineers who model growth projections for a living — to prepare the 2017 Character Plan. They knew about the development pipeline. They still specified two lanes. If population growth invalidates the 2017 study, why did the county commission it?
Nobody is arguing Darden Hill needs zero improvements. A two‑lane road with turn lanes handles significantly more traffic than a bare two‑lane road — that is exactly what the county's own engineers recommended. The jump from "center turn lane" to "four‑lane divided highway" is not a proportional response to growth. It is a different kind of road entirely.
And the county's own justification undermines itself. Commissioner Smith cited the elementary school as a reason for widening — but building a 45 mph four‑lane arterial past the school you are citing as justification is incoherent. More children on the road is an argument for lower speeds and fewer lanes, not a highway.
Wider, faster roads do not just accommodate traffic — they generate it. This is established transportation engineering, known as induced demand. A four‑lane highway will attract regional through‑traffic that currently uses other routes. The county is not responding to traffic. It is inviting it — directly past our homes and our children's schools.
Environmental sensitivity
Darden Hill Road sits within the Onion Creek watershed and the Barton Springs Contributing Zone, subject to TCEQ Edwards Aquifer protections (30 TAC Chapter 213). Higher‑volume, higher‑speed roads produce significantly greater stormwater runoff carrying heavy metals and petroleum compounds into this sensitive watershed.
Voters said no. The county found a way around it.
The 2024 Hays County road bond was voided by a judge in 2025 for violating the Texas Open Meetings Act. Rather than respect that outcome, the county approved up to $240M in Certificates of Obligation — public debt that does not require voter approval — to continue advancing these projects. The Save Our Springs Alliance has been involved in challenging the county's approach. Under Texas Local Government Code §271.049, a petition signed by 5% of registered voters can force the county to hold an election before issuing COs.
The Alternative
We are not saying no. We are saying do it right.
We are asking for the two‑lane design that the county's own studies recommended — one that serves the families who live here, not the through‑traffic that doesn't.
Reduce to two lanes with turn lanes at intersections
A "Super 2" configuration — a standard design for growing rural communities. In rural and suburban settings, the capacity constraint is almost always at intersections, not the stretches between them. Turn lanes at intersections solve the actual bottleneck. Four lanes between intersections is over‑engineering a problem that doesn't exist — at significantly greater cost to taxpayers.
Set the speed limit at 35 mph
Matching Sawyer Ranch Road and consistent with a road adjacent to schools and residential properties.
Remove the planned future extension
Allow local traffic to develop with community growth rather than pre‑building a regional bypass through a residential area.
Establish a truck weight limit
Heavy freight has no place on a road where children bicycle to school and teenagers are learning to drive. A weight restriction ensures Darden Hill serves residential traffic, not regional trucking.
Design for the people who live here
Families, students, and residents — not regional freight and commuter through‑traffic.

Suggested questions for Commissioner Smith
- — Why does the current plan call for four lanes when the county's own 2013 and 2017 studies recommended two lanes?
- — Has the county prepared a cost‑benefit analysis comparing the four‑lane plan to a two‑lane alternative?
- — How does the county reconcile 45 mph traffic adjacent to school campuses with the stated goal of pedestrian and cyclist accommodation?
- — Why were Certificates of Obligation used to advance a project whose bond funding was successfully challenged in court?
