Case ZONE-26-0007 · Town of Prosper
Protecting…
Our Families.
Our Water.
Our Future.
We invested our hard-earned money, our lives, our families and our futures here – in Prosper, Aubrey, Celina and the communities around them. We chose neighborhoods still close to open space for a reason: fields of longhorns, ag land, acres of wild sunflowers, wooded creek beds.
Now a Dallas developer wants to rezone 37.3 acres at FM 1385 and Parvin Road for a data center beside neighborhoods already here. Other affected community amenities include a preschool/daycare, several elementary and middle schools, and a planned senior living community.
It's time to mobilize to protect our families, our water, and our future.

What is being asked for
What the Town of Prosper is being asked to approve
A Dallas developer wants to build a data center on 37.3 acres off FM 1385. The company is White Rose Partners. They call it Project Tomahawk. The land is farm land today, and the Town of Prosper's plan calls for homes, shops and a business park here. Two requests are on the table to change that.
- 37.273 acres
- White Rose Partners of Dallas
- Project Tomahawk
- Farm land to Planned Development
- Up to 60 feet tall
- Covers 20% of the lot
Request one
Rezone the land
The land is zoned Agricultural today and it is empty. The developer wants it rezoned to a Planned Development that allows a data center. The tract is 37.273 acres, or 1,623,594 square feet. It is part of the Parvin 1385 Addition, Block A, Lot 2. It sits about 1,590 feet south of Parvin Road and 855 feet east of FM 1385, behind the shops and offices planned to the north and behind the Brazos Electric substation that fronts the road.
Request two
Change the Town of Prosper's plan to match
The Town's Future Land Use Plan calls for a business park, high density homes, and neighborhood shops on this land. A data center is none of those. So a second request was filed to change the plan itself. Families nearby read that plan before they bought. It told them what could go up next door.
The rule book
The Town has no rules for data centers.
A data center is not a defined use in Prosper's zoning ordinance. There are no guidelines for planning or zoning one. So the rules for this project get written into its own Planned Development, one project at a time, starting with this one.
What is in the plan
What the developer is asking to build
- The use. A data center and the utilities that run it. The standards are custom, written for this project.
- The footprint. Buildings would cover about 20% of the lot. The rules would allow up to 50%.
- The height. 40 feet, plus up to 20 more feet of screened roof equipment. That is about four stories.
- Getting in. Two driveways, both through the commercial land to the north. That land is building a 65-foot road linking Parvin Road to FM 1385.
- The trail. A 10-foot hike and bike trail is required along the north and east edges.
A note from the neighbors
Full funding to widen FM 1385 is not expected until 2030 or later. Neither Parvin Road nor FM 1385 can carry heavy construction traffic. Both are already crowded and unsafe. That will not change in the next 12 to 18 months.
The size of the problem
There is not enough room on 37 acres.
Everyone agrees a data center brings something. The noise, the traffic during construction, the lights, the power draw: the developer's own materials talk about handling all of it. Handling it takes space. Distance is what protects neighbors, and distance is the one thing this site does not have to give.
The lot is 37.3 acres with a power substation already beside it. The rules set the buildings 60 feet back and put a row of shrubs along the edge. Sixty feet is four car lengths. That is what stands between this and the homes already here.
What the rules actually say
The rules do not mention noise. They do not mention water.
A Planned Development writes its own rules into the zoning. Once the Town votes yes, those rules are what the owner must follow. Here is what the rules for this one cover:
- How far buildings sit from the property line: 60 feet on every side
- How tall they can be: 40 feet, plus 20 more feet of roof equipment
- How much of the lot they cover, and what they are built from
- What gets planted along the edges
And here is what the rules do not cover:
- Noise. There is no decibel limit anywhere in them.
- Water. There is no cap on how much it can use.
The developer has talked about a 65 dBA noise limit and about using 300 gallons of water a day. Neither number is in the rules. Town staff wrote that the only changes from normal commercial zoning are bigger yard setbacks. Nothing else.
Where
Off FM 1385, south of Parvin Road
Northwest Prosper. The land to the east is already zoned for single family homes. The closest big neighborhood is Sutton Fields. The closest school is Pat Hagan Cheek Middle, a Denton ISD school just under half a mile from the site boundary. Moseley Middle, in Prosper ISD, sits north and east of the one mile ring. There is also a plan for Prosper Oaks, up to 525 homes for seniors, on Parvin Road east of FM 1385.
The buildings would stand 60 feet from the property line. That is about four car lengths. With roof equipment they could reach 60 feet tall, or about four stories.
Point at anything on the map to see what it is.
- Proposed data center, 37.3 acres. Indicative boundary, not a survey.
- Existing Brazos Electric "Parvin" substation, between the site and FM 1385. Position approximate.
- Rings at a quarter, a half and one mile from the middle of the site.
-
Schools, by distance from the site boundary. Only campuses whose position we have confirmed are pinned. Moseley Middle, Prosper ISD, sits beyond the one mile ring to the north and east; it is named here rather than pinned because no coordinate for it could be confirmed.
- 1 Sandbrock Ranch Elementary, Denton ISD 0.94 mi
- 2 Pat Hagan Cheek Middle, Denton ISD 0.45 mi
- 3 Union Park Elementary, Denton ISD 1.21 mi
Mapped homes inside each ring: about 50 within a quarter mile, 590 within a half mile, 3,100 within one mile. The nearest mapped home sits about 200 feet from the site boundary. Home counts come from OpenStreetMap building outlines, rounded down. Distances are measured from the outline shown, which is indicative and not a survey.
The noise
The noise limit they offered is 25 decibels louder than the level doctors say protects sleep.
The developer has offered a limit of 65 dBA at the property line. That is about as loud as someone talking three feet from your face. Not for one evening. At 2 a.m. in February, and every hour after that, for as long as the building stands. And it is not written into the rules.
None of these numbers account for the added decibels or the EMF from the upgraded substation. Those come on top of what you see here.
Hear it
The same sound, 25 decibels apart.
Play the first one. Turn your volume up until you can just hear it. That is about as loud as a quiet bedroom at night. Now play the second one, and do not touch the volume.
Your volume knob sets how loud this really is. What is exact is the 25 dB gap between the two. That is about six times as loud to your ear. Now picture the second one never shutting off.
Because decibels are logarithmic
65 dBA is not "a little above" 40 dBA. The scale doubles every 10 points. So the gap here is huge. And the same number applies at 3 a.m. as at noon.
Measured at the fence, not the window
A property-line limit is a limit at their fence. Noise rules near homes are usually measured where people sleep. They also drop at night. This one does neither.
And on the worst days, it is generators
A 2025 state law lets the power grid order big users onto backup generators when the grid is strained. That happens on the hottest days of a Texas summer. The days windows are open and kids are outside.
What the research says
Night noise does not just annoy people. It does damage.
Every number here has a link. Open them. The whole point of this page is that it holds up.
The level where harm starts. The World Health Organization calls this the point where night noise begins to cause real effects: broken sleep, insomnia, and more use of sleeping pills.
WHO Night Noise Guidelines for Europe, 2009Above this, the WHO says the situation is “increasingly dangerous for public health.” Those are their words, not ours. The limit on offer here is ten points higher than that.
WHO Night Noise Guidelines for Europe, 2009How much your blood pressure jumps during a night noise event. The researchers found this happened whether or not the sleeper woke up. Your body reacts even when you never know it happened.
European Heart Journal, 2008 (HYENA study)The rise in heart disease risk for every 10 decibels louder it gets outside your home. The WHO reviewed seven long-term studies and rated this evidence high quality.
WHO systematic review, 2018How far behind in reading children fell for every 5 decibels of extra noise at school. Two thousand kids, three countries. There was no safe level: the louder it got, the further behind they fell.
The Lancet, 2005 (RANCH study)Healthy young adults slept through a night at this level and showed no change in their sleep at all. They still woke up with more stress hormone the next day.
Environmental Research, 2020Two honest notes. The reading study measured airplane noise, not a data center, so treat it as the closest good evidence rather than a perfect match. And people do not get used to it: researchers found that those who had lived with night noise for years still reacted to it every time. European Heart Journal, 2014
And the measure itself is generous
A hum does not show up properly on the meter.
How much the standard measure undercounts a low hum. Cooling fans and transformers make deep sound. Two noises can read the same on a meter, and the low one will still bother you more. The researcher who measured this wrote that judging low noise this way “leads to incorrect decisions by regulatory authorities.”
Noise & Health, 2004Closing them will not fix it. Deep, low sound passes through walls and glass far better than traffic noise does. Better windows are the usual answer offered to neighbors. For a hum, they do very little.
Building and Environment, 2019So here is a fair ask: any noise study should report the low-frequency bands and the C-weighted level, not one A-weighted number. And sound standards already say a steady hum should have 3 to 6 points added to its score. If the developer's study skips that, it skipped a step the standard requires.
Target ordinances for data centers
Other places have already decided 65 dBA is too loud.
The places with the most data centers have decided that the usual industrial limits, which often allow 60 to 65 dBA, are too loud to live beside. Their limits are coming down fast.
| Place or standard | Night limit | What it is |
|---|---|---|
| Loudoun County, VirginiaThe world's largest data center market | 40 dBA | Enhanced-zone night limit |
| Divide County, North Dakota | 45 dBA | Strict cap on steady noise |
| Sierra Club model ordinance | 40 dBA | Recommended limit, plus a penalty for a steady hum |
| Prince William County, Virginia | 55 dBA | The old standard. Rewritten in 2026 after residents said it did not stop the hum. |
Prosper can and should demand a lower limit.
Prosper has its own noise rule. It covers sound within 500 feet of any home. If the Town of Prosper's night limit is under 65 dBA, then what the developer offered is weaker than the law already requires. The Commission should say so out loud.
We chose these neighborhoods for a reason.
Some of us came here to start a family. Some came for a retirement that was peaceful and that we could afford. Either way, we put everything we had into it. Everything we put in is now at risk, and none of us could have seen it coming to our back doors.
We use technology every day and we are glad it exists. There is simply not enough room on 37 acres to make this project work for the people who already live here. Not with a power substation already beside it. Not with this many homes around it.
This is a bait and switch.
Fair Questions. Still Unanswered
Where are the answers to the questions that matter?
Every number offered so far sits in a slide deck. None of it sits in the rules. After the vote, a slide deck holds nobody to anything.
Power
How much, and what does it do to our bills?
- How much power will Project Tomahawk actually use?
- What can the Brazos substation carry today, in megawatts? What will it carry once it is upgraded?
- What does that upgrade do to the land and the air, on top of the data center itself?
Governor Abbott has called for these projects to bring power bills down for the people who live near them. Nobody has shown us that the Town of Prosper asked for that, or that White Rose Partners or whoever ends up running the building will agree to it.
We should know all of this before a vote, not after.
Water
Is the promise real, or is it a brochure?
The developer says the cooling system reuses its water and uses about 300 gallons a day. That may well be true. It is in no rule, because Prosper does not have one. Put it in the rules with a way to enforce it and it is a promise. Leave it out and it is a preference.
- How much water does it take to fill the system the first time?
- How often does it have to be flushed or serviced?
The project is expected to use 110,000 gallons a year. A White Rose Partners document says the closed-loop system needs 425,000 gallons for the first fill alone. We already live under water restrictions. Prosper should require a data center to truck in its own water. Telling neighbors when they may run a sprinkler, while this goes in beside them, does not add up.
Transparency
Who is this actually for?
White Rose Partners resells powered land. Governor Abbott has called on data centers to say plainly who they are and what they do. Nobody has.
- Who is the end user, and what will they run here?
- If the developer makes a promise on paper, who keeps it once someone else owns the building?
- What happens if they do not?
The studies
Put them out in full, before the vote.
The developer paid for studies on noise, power and water, and quoted pieces of them. Town staff pulled this item off the August agenda to read the whole thing. We should not have to answer a quote.
What the petition asks for
What we are asking the Town of Prosper to do.
We, the residents of Prosper, Aubrey, Celina and the surrounding affected communities, ask the Town of Prosper to:
-
01
Deny Case ZONE-26-0007
Say no to the rezoning, and no to changing the Town of Prosper's plan to match it.
-
02
Freeze data center plans until there are real rules
Prosper residents should be able to rely on the Town of Prosper's planning department to stick to their word and define the rules when it comes to planning decisions. Pause new data centers until those rules exist. Right now Prosper has no definition for a data center, and no standard to judge one by.
-
03
Ask the community first
Ask the people who live here what this land should become. Ask them what kinds of development projects they would support. Do that before anything is approved, not after.
-
04
Meet the standard the Governor has set
Texas has been clear about what these projects must do:
- Put communities first.
- Protect our water and the power grid.
- Respect the quality of life for residents already here.
- Hold this project to that standard.
Read the Governor's statement here and judge for yourself just how far short this project falls from those requirements.
This is not a long shot
Texas towns have said no this year.
A June 2026 poll found that most Texans do not want a data center in their own town. The Governor has called for rules on where these can go. In August he ordered a state review of every data center waiting to plug into the power grid.
Westlake is the one that got through. Neighbors showed up and petitioned against it, and they did not get their way. Now neighbors in Keller are suing to stop the project.
Showing up is not a promise. It is just the only thing that has ever worked.
What to do, and when
The hearing is Tuesday, September 1.
The Prosper Planning & Zoning Commission hears this on Tuesday, September 1. It is Items 4 (rezoning) and 5 (project development) on the agenda. Residents get to make public comment. The Commission will make a recommendation and pass it to the Town Council. The Council makes the final decision on September 8 or September 22. Check the posted agenda for the date.
Do not waste time arguing about this project on social media. The only thing that counts is putting your opinion on the public record, and the record starts here, with you in the room and your comment read out. Details below.

Opening it in your email app does not send anything. You still press send.
After September 1
This is not the last vote
Planning & Zoning votes on a recommendation. The Town Council makes the real decision, at a later meeting. So there are two rooms to fill, not one. Agendas go up at least 72 hours ahead.
- Planning & Zoning: 1st & 3rd Tuesdays, 6:15 p.m.
- Sept 1 · Sept 15
- Town Council: 2nd & 4th Tuesdays, 6:15 p.m.
- Aug 25 · Sept 8 · Sept 22
Add your name above and we will email you before each one. That is the whole reason the list exists.
If you have never done this before
"Good evening. My name is [name]. I live at [street]. I am here about Items 4 and 5, the data center on Parvin Road.
I read the rules in this request. They set how far back the buildings sit and how tall they are. They say nothing about noise. They say nothing about water.
The developer has offered numbers for both. I am asking you to put those numbers in the rules, where someone can hold them to it. A promise that is not written down is not a promise.
Until that happens, I am asking you to vote no. Thank you."
That takes about 40 seconds. Add one line about your own family and you are at a minute. That is plenty. Clear beats loud.
Straight answers
Questions we keep getting
Does signing this petition legally block the rezoning?
No. Anyone who tells you it does is setting you up. This is a public petition. Its power is political. It shows the Town of Prosper how many of us object, and it builds a list we can call on before each vote.
There is a second kind, and it is not the same thing. State law allows a formal protest petition. That one counts land, not people. Only owners near the site can sign it, and it counts how much land they own. If enough of them sign, the Town Council needs more votes to approve. The rules changed in 2025. If you own land near the site, tell us on the form. We are consulting with lawyers to get this right.
Aren't you just against progress?
We use technology every day and we are glad it exists. We are for planning that leaves enough room to handle what a data center brings. Put this on land already marked for industry, with room around it, and we have no fight. This one needs the Town of Prosper to rewrite its plan so it can sit near homes, a preschool and a middle school. That is a different question.
Won't it lower my property value?
The research here is mixed, so here is the honest version. One large study of home sales in Virginia found no lasting drop in prices. Another found prices went up county-wide. But most of that work looks at buildings miles from homes, not one at the fence. So it does not really answer our question.
What agents in this market see up close is different. Homes beside a data center site sit on the market longer, and time on the market is price pressure. A buyer with a choice takes the house without the fence line.
We would rather win on the facts that hold up. The rules set no noise limit. They set no water cap. And the Town of Prosper is being asked to change its own plan to make this fit.
Didn't the state already pause data centers?
Not this one. Let's be exact. In August the Governor ordered a review of every data center waiting to plug into the power grid. That is about the grid, not about zoning. It does not stop Prosper from voting. What it does tell you is that the state thinks the power and water questions are serious enough to pause hundreds of projects.
Will you sell or share my information?
Never sold. Never rented. Never handed to a campaign, a party, or an advertiser. We give the Town of Prosper your name and your part of town, because that is what signing means. Anything given to the Town becomes a public record. We never publish your street address or your email, and every email has an unsubscribe link. The full privacy policy spells all of it out.
