Lost Creek Voted Itself Out of Austin. What Does a Buyer Actually Inherit?

A Lost Creek home's tax history can show a year that no longer matches how the neighborhood is governed. In 2024, owners in the subdivision off Loop 360 got City of Austin tax bills even though they had voted to leave the city that May. Those bills came to about $5.2 million across the neighborhood. The City then said it could keep taxing Lost Creek for two more years to cover the neighborhood's share of City debt. In July 2025, a Travis County district judge ruled that it could not.

So the history attached to a Lost Creek address covers several different tax setups in a row, and the latest public reporting left part of that history unsettled. For anyone weighing Lost Creek against Rollingwood, West Lake Hills or Barton Creek, this transition explains the numbers better than any median price does.

The Tax Year in the File Comes From a Different Arrangement

The order of events matters. In 2015, the City annexed about 738 acres of Lost Creek under a strategic partnership agreement. On the same day, it converted the old Lost Creek MUD into the Lost Creek Limited District. In 2023, the Texas Legislature passed House Bill 3053, which gave the area an election. On May 4, 2024, 91.29% of Lost Creek voters chose to disannex. The Austin Bulldog put the count at 1,450 to 138.

The City's disannexation ordinance took about 657 acres out of the full-purpose city limits, effective September 9, 2024. City-owned property stayed inside the city. Part 5 of the ordinance says the City will keep taxing the area at the citywide rate "until the taxes collected from the area equal its pro rata share of the indebtedness." The City's 2024 letter to residents expected tax years 2025 and 2026 to cover that share, with bills due in January 2026 and January 2027.

That plan didn't hold. The Lost Creek Neighborhood Association and two residents sued. On July 17, 2025, Judge Catherine Mauzy granted partial summary judgment barring the City from collecting Lost Creek property taxes for 2025 and 2026. The City had put the neighborhood's share of its debt at $7,772,513.84. In a deposition filed in the case, a City budget official testified that giving up Lost Creek's share would not affect the City's ability to pay its debt. Lost Creek's 1,224 parcels make up about 0.4% of the City's taxable value.

At that point, a trial on whether the 2024 City taxes would be refunded had not been scheduled. We found no public reporting after July 2025 on an appeal, a settlement, a trial date or how 2025 bills were actually issued. A buyer in October 2026 is reading a tax history in which 2024 includes the City levy, the next two years were the subject of a court order, and the refund question was still open at the last report.

The 2026 Stack, Line by Line

Travis County's adopted 2026 rate table shows what goes on a Lost Creek bill now. These are the taxing units that typically apply to a home in the neighborhood, at rates per $100 of taxable value:

For tax year 2026, the City of Austin's citywide rate is $0.579948, made up of $0.444636 for operations and $0.135312 for debt. On a home with $1 million of taxable value, before exemptions, the rates in the table come to about $15,616 a year. The City's rate on the same value would add about $5,800. That gap is the amount the court case is about. It also explains why a 2024 bill in a seller's records can't be compared directly with what the next owner will pay.

The district's own line is small. The Limited District's rate went from $0.032559 in 2025 to $0.035537 in 2026, and the county lists no debt rate for it. The district's website shows the 2026 figure as "$ 0.35537," which looks like a misplaced decimal. The county's table matches the scale of the 2025 rate.

What Moved Off the City's Ledger

A lower tax total doesn't mean a lower cost of ownership, because some services the City used to cover now come from other providers. Here is what changed on September 9, 2024, according to the City's letter to residents and the ordinance:

1. Trash, recycling and compost. Austin Resource Recovery stopped curbside pickup. Each customer was billed a $24.64 fee for removing the old carts. The Limited District now names Texas Disposal Systems as its preferred provider.
2. Fire and police. Austin Fire and Austin Police no longer provide primary response. Travis County ESD No. 9 and the Travis County Sheriff's Office do. Austin-Travis County EMS still handles emergency medical calls. ESD 9's rate is the $0.077900 line in the table above.
3. Utilities. Nothing changed. Austin Water still provides water and wastewater, and Austin Energy still provides electricity.
4. Permits. Lost Creek is now in Austin's extraterritorial jurisdiction. The City's letter says some City regulations may still apply and that projects may also need Travis County permits. This matters most for buyers planning an addition or a full remodel, because one project may involve two agencies.
5. Streets and streetlights. The City stopped maintaining both when the disannexation took effect. We could not confirm from a primary source which entity maintains Lost Creek's public roads today.

Item 5 links to the most current part of the story, because it is still on the Limited District's agenda.

A $554,170 Government That Is Rebuilding Greenbelt Stairs

The Lost Creek Limited District describes itself as a local government with limited authority. Its board members are elected to staggered four-year terms. It maintains Lost Creek Boulevard Park, Boulder Trail Park, the Whitemarsh Valley Nature Trail, the district office and community center, the landscaping at the entrances and medians, and its land along the Barton Creek greenbelt. It also enforces deed restrictions.

The district's adopted budget for fiscal 2026–27 is $554,170, up 1.8% from $544,276 the year before. The budget includes $74,256 for neighborhood security patrols, $40,000 for Firewise clearing and $131,656 for greenbelt expenses. The capital plan sets aside four payments of $87,500, or $350,000 in total, for greenbelt stairs. The district's homepage says the board approved rebuilding all five trail access stairways and that work is starting.

This is the part of Lost Creek that a buyer can see on the ground. The neighborhood's access points to Barton Creek are being rebuilt with money from a tax rate of about three and a half cents per $100 of value. The same small budget covers smaller requests too. The September 15, 2026 agenda included an application from the Lost Creek Moms Club to hold a Movie Under the Stars at Boulder Park on November 20, 2026. Most governments are too large to put a park movie night on a board agenda. This one isn't.

What Is Still on the Agenda

The same September 2026 agenda shows how much of the transition is still being worked out. Under the heading of disannexation, it listed three items: post-disannexation services, grouping solid waste, road maintenance, recycling and stormwater drainage together; the strategic partnership agreement with the City of Austin, for discussion and possible action; and the release of land from Austin's extraterritorial jurisdiction, for discussion.

Each of these could change what Lost Creek ownership costs or how it works. If road and drainage responsibility settles with the district, the county or someone else, that decision will affect future budgets. If the land leaves the ETJ, permitting would change again. The 2015 agreement has also not been shown to have ended. A buyer's file is more complete when it has the district's latest agenda and budget, the current Travis County rate table and the most recent property tax statement next to the listing's tax history.
