Hays Commons: An Uncommonly Bad Development

If you wanted to build a big subdivision in a really bad place, where would you put it? Would you build it in a place with lots of rocky gaps and cracks on the ground that would allow dirty surface water to seep into the Edwards Aquifer, which provides water for hundreds of residential wells as well as Barton Springs Pool? Unfortunately, this is exactly where Milestone Community Builders wants to put its Hays Commons subdivision, a 498-acre subdivision that would be located in one of the worst places possible — over the Recharge Zone for the Edwards Aquifer.

Milestone is even asking Austin’s officials to help them make this subdivision worse. The developer is demanding an unprecedented concession from the city that would let it build Hays Commons with 25% impervious cover instead of 15%, which is the maximum amount that would otherwise be allowed under the Save Our Springs Ordinance for new construction over the Recharge Zone. The additional impervious cover — roofs, streets, and parking lots — would produce even more dirty stormwater runoff that could seep into the Edwards Aquifer.

On January 14, members of Austin’s Planning Commission will vote on whether to give Milestone this concession, which would require amending the SOS Ordinance. SBCA urges you to attend the meeting and tell the commissioners that they shouldn’t undermine the SOS Ordinance just for one subdivision. We’ll post more details later this week on how to attend and speak at the Planning Commission meeting.

And on this Tuesday, January 7, you can prepare for the Planning Commission meeting by joining SBCA and our coalition partners at the Hays Commons Community Meeting. Speakers from SBCA, Save Our Springs Alliance, Greater Edwards Aquifer Alliance, Austin Sierra Club, and Hays Residents for Land & Water Protection will explain what’s wrong with Hays Common, and answer your questions about what to say at the Planning Commission meeting. The Hays Commons Community Meeting will be held at 6-7pm on Tuesday, January 14, at the offices of Save Our Springs Alliance, 4701 West Gate Boulevard, Suite D-401, Austin, TX 78745. You can attend in person or via Zoom by registering either on Facebook or Zoom.

 

 

Where is Hays Commons?

Milestone Community Builders is proposing this subdivision for a 498-acre property located west of Manchaca and north of Buda at the intersection of SH 45 and FM 1626. Milestone plans to build 700 single-family homes and 12 acres of commercial space, with a projected population of 2,500 people.

 

What’s so bad about the location?

Don't let White Rocks crush the Golden-cheeked Warbler!
Building a huge outdoor concert amphitheater right next to a wildlife preserve would be insane. And using the wildlife preserve to sell multimillion–dollar luxury condos would be obscene. But unfortunately, this is exactly what the developers of the White Rocks resort want to do. They plan to build a 10,000-seat amphitheater, plus a luxury hotel and condos, on a property west of Austin that’s ...
Public meetings on Hays County development rules: July 28-29
Hays County has been growing fast, and it's only going to get bigger, with a projected population of 550,000 in just 16 years. That's why Hays officials are in the process of rewriting the county's development regulations, which are especially important since many new subdivisions are being built outside of city limits and ETJ areas. In these unincorporated areas, county regulations are the onl...
Hays Commons: Still a threat to the Edwards Aquifer
The Hays County Commissioners Court voted 3-1 last month to reject a development agreement for Hays Commons, a planned subdivision that would be built over the Edwards Aquifer Recharge Zone on the Hays-Travis county line. Does this mean that the proposal is dead? Unfortunately, no. Milestone Community Builders, the Austin-based developer behind Hays Commons, has been working multiple angles sin...
