If you have been comparing Norwalk against Ankeny, Waukee, or the other fast-growing edges of the Des Moines metro, you have probably run across the headline by now. On March 5, 2026, the Norwalk City Council approved a development agreement with Tract, a Colorado-based developer, to build a $12 billion data center campus on the city's southwest edge. Local coverage has already called it the largest private investment in Warren County's history.
That number is real. It is also not the number that should change how you think about Norwalk as a place to buy a home.
The number that matters is 80. That is roughly how many permanent jobs the finished campus is expected to support once it is operational, compared to about 600 temporary construction jobs during buildout. A $12 billion project that employs 80 people long-term is not a jobs story. It is a tax-base story, and the difference matters if you are trying to figure out whether Norwalk's growth is the kind that shows up in your property tax bill, your commute, or your water pressure.
What Project West Actually Is
The site sits on 282 acres the city annexed in January 2026, positioned west of Highway 28, south of Delaware Street, and north of the North River. It is part of a much larger annexation, nearly 3,000 acres to the southwest of Norwalk's current limits, that city leaders have framed as a long-term strategy to eventually connect Highway 28 to Interstate 35.
That larger annexation was still tied up in an appeal when the council voted on the 282-acre parcel specifically for the data center project. City officials moved on the smaller piece because they were not willing to lose the developer while the appeal worked through the courts.
City attorney Jim Dougherty put the calculus plainly at the council meeting, noting that the parties involved did not think they could afford to wait out a potential year-long appeal process. The city says it does not yet know which company will actually operate the facility. Tract's business model is to acquire and prepare data center sites, then hand them off to end users, so the tenant remains unannounced even after the land deal is approved.
If construction proceeds on the projected timeline, infrastructure work could start as early as this summer, with the facility potentially operational by 2030.
The Math That Doesn't Match the Headline
Here is where the story gets useful for anyone actually deciding whether to buy in Norwalk. The city's own projections put the site's taxable valuation between $400 million and $500 million once built out, generating roughly $15 million a year in new tax revenue.
That is a meaningful new commercial tax base landing in a city of Norwalk's size. It is also a tax base that does not come with a proportional new workforce.
| Project West, by the numbers | Figure |
|---|---|
| Annexed site | 282 acres |
| Projected taxable valuation | $400M to $500M |
| Projected annual new tax revenue | ~$15 million |
| Construction jobs (temporary) | ~600 |
| Permanent jobs once operational | ~80 |
| Earliest infrastructure start | 2026 |
| Projected operational date | 2030 |
Read the table as a sequence rather than a list. A large one-time construction employment bump, followed by a small permanent staff, sitting on top of a large new commercial tax valuation. That pattern is common with data centers nationally. What makes it locally relevant is that Norwalk is building its infrastructure pipeline right now, in the same window this deal was approved.
Where the City Is Actually Spending Right Now
Norwalk's public works department has a running list of active infrastructure projects, and several of them describe exactly the kind of buildout a project like this requires. The city is constructing a new 1.5 million gallon water tower on the north side of Chatham Avenue, east of 18th Street, with construction slated to begin this year. A large-diameter sanitary sewer extension is already progressing westward from the city's storage lagoons on the south side of Norwalk, explicitly intended to serve growth areas south and west of the currently developed part of the city, which is the same general direction as the Project West site.
Separately, the North Avenue and Highway 28 corridor project moved from utility relocation into major construction this spring, after months of prep work. The city is also replacing aging 4-inch water mains with 8-inch mains and adding fire hydrants along Elm Avenue and Snyder Avenue in the Founders area, and has been patching and re-striping Colonial Parkway and Colonial Circle near The Legacy this spring and summer.
None of these projects are billed publicly as data center infrastructure. But the sewer extension's own stated purpose, serving growth south and west of existing development, lines up with where the annexed site sits. If you are weighing Norwalk against a suburb with a more conventional, population-driven growth pattern, this is the detail that separates the two: some of what looks like standard municipal upkeep here is being sized for a commercial deal that has nothing to do with how many families are moving in.
West Des Moines Already Ran This Experiment
Norwalk is not the first Des Moines metro suburb to host a large data center. West Des Moines already does, through Microsoft. According to reporting on the Project West approval, Microsoft's data centers in Iowa employ more than 500 people statewide, with a projected 752 full-time employees and contractors across its operational facilities by the end of 2026.
More specific to West Des Moines itself, city and utility figures cited in that same coverage put Microsoft's data centers at 2.6 percent of total water pumped to local customers, rising to about 6 percent during peak demand periods. Microsoft has also committed $25 million toward water infrastructure to support the local utility.
Those numbers describe a data center presence at steady state, years after construction. Norwalk is still at the front edge of that curve. Whichever company eventually operates the Project West campus will make its own water and infrastructure commitments, but the West Des Moines figures give you a real, comparable range for what "small permanent footprint, meaningful utility draw" looks like once a facility is running rather than being built.
What This Changes If You're Comparing Suburbs
None of this means Norwalk is a riskier or better buy than Ankeny or Waukee. It means the growth signal you are reading is different from the one those other suburbs are sending.
Zillow's home value index for the Norwalk zip code put the average home value at $346,379 as of June 30, 2026, up 1.8 percent over the prior year, a modest and fairly ordinary appreciation rate for the metro. New construction inside The Legacy, one of Norwalk's most active builder communities, listed at a median of $309,000 in June 2026, working out to $234 a square foot. That is actually below the citywide median list price of $349,945 recorded in a late May 2026 market snapshot, where the average listing had been sitting for 108 days.
New construction pricing below the resale median is not what you would expect if population-driven demand were the main thing pushing Norwalk's market. It fits better with a builder-volume story: communities like The Legacy are priced to move units at scale, which is a different growth mechanism than families competing over a shrinking pool of resale homes.
The Project West annexation adds a second, distinct growth mechanism on top of that: a commercial tax deal that funds infrastructure without adding much local employment. If you are trying to project where Norwalk's property tax base and public spending are headed over the next several years, that commercial valuation matters more than any single new subdivision.
A Few Direct Questions
Will this affect my property tax bill right away? Not immediately. The projected $15 million in annual tax revenue depends on the campus being built out and assessed at its projected valuation, a process that will take years given the 2030 target for operations.
Will construction traffic or utility work affect my daily routine this year? Possibly, depending on where you are looking. The North Avenue and Highway 28 corridor work and the Colonial Parkway restriping near The Legacy are both active in 2026, separate from the data center site itself but part of the same broader infrastructure push in that part of the city.
Comparing suburbs on price per square foot only tells part of the story.
