For a new Wright City home on district sewer, the cost of hooking up shows up in two places. Before a new connection is made, Public Water Supply District #2 charges a system-development fee based on the size of the main. Its rules also let the district spread the cost of sewer improvements across lots as a surcharge when each lot connects. After move-in, the monthly bill applies. Under the district's Rate Code B schedule, which covers Wright City, billings since June 1, 2026 carry a $3.50 monthly user charge plus $9.69 per 1,000 gallons, with a minimum of $47.86 a month at 4,578 gallons. Under the 2024 schedule, that minimum was $41.00.
The plant those homes connect to exists mostly because of a beef processor. That plant took away the constraint that had kept Wright City small. Today a different constraint governs: the city's zoning code, enforced one public hearing at a time, and it shapes which new-construction prices reach buyers looking west along I-70.
The Lagoon Was the Ceiling
Until recently, Wright City's wastewater went to a lagoon system rated for 500,000 gallons a day. In May 2025, the district's executive director, Kevin Dunn, told the Warren County Record that before the expansion, the facility was under an order of consent from the Missouri Department of Natural Resources for exceeding its capacity and its limits on ammonia. He also said the public side was sending in roughly 500,000 gallons a day, which was the old plant's entire rating.
A plant running at its limit can't take on new subdivisions. A meatpacker's need for wastewater capacity paid for the fix, in this order.
- April 10, 2025: American Foods Group's America's Heartland Packing plant began operating outside Wright City. The Record reported about 400 workers at opening, with 1,300 expected at full production.
- May 2025: Parts of the new treatment plant were already running. AFG was handling the design-build and paying part of the cost.
- September 2025: On a tour, AFG reported about 600 employees, a goal of 1,300 to 1,400 at full capacity, and capacity to process 2,400 cattle a day.
- December 18, 2025: Contractor Alberici announced the completed facility and its ribbon-cutting, describing it as support for future residential and commercial growth.
The new plant handles 3.5 million gallons a day. Of that, 1.5 million is reserved for the packing plant and 2.0 million for the Wright City area, which is four times the old municipal capacity. The engineering firm Woodard & Curran puts the cost at $133.5 million and says it came in $8.1 million under budget. Earlier Record coverage cited a $140 million figure. The firm says the expansion "positions Wright City to accommodate residential and commercial development without additional infrastructure investment in the near term."
The rate schedules don't say whether the higher sewer bill is connected to the new plant. The bill went up between the 2024 and 2026 schedules, and the documents give no reason.
Four Times the Headroom, and Proposals Still Get Turned Down
With sewer capacity no longer the limit, the city's Planned Development Area zoning decides what gets built. Wright City created the PDA district by Ordinance 1010 on December 9, 2021. It works as a separate zoning district that allows some flexibility from standard lot-size and setback rules. That flexibility has limits. The current code, as amended through Ordinance 1095 in November 2025, ties residential PDA density to the SR-2 district's minimum density and area requirements. The code's general provisions list SR-2 at 21,780 square feet. Housing density can't exceed the site-wide limit of the matching district. Common open space has to be at least 15 percent, while clustered developments need 40 percent within the cluster and 35 percent across the whole site.
The city has applied these rules case by case:
- Serenity Woods was approved on July 26, 2024. The 53-acre plan set aside 40 percent for open space and amenities, and approval came with conditions on an emergency-only gated access road and on finishing amenities by phase two.
- Vista on the Park West, a mixed-use plan with 114 apartments and townhomes, received unanimous zoning approval on December 26, 2024. The developer agreed to a crosswalk, an acceleration lane and a per-unit road-impact fee.
- The District at Roelker asked for mixed-use PDA zoning on about 58 acres for 190 homes and commercial lots. The aldermen sent it back to Planning and Zoning in September 2024. In November, the Record reported that the board postponed a decision after the commission voted four to two against the development.
At a May 2026 work session, Planning and Zoning Commission member Ramiz Hakim said four subdivisions had come before the boards under PDA zoning. Two were approved and two were voted down. At the same meeting, Mayor Michelle Heiliger described the trade-off the city is weighing, as reported by the Warren County Record:
"The question that we have is do we provide enough of a variety of types of housing that people that live in our community can stay here."
The Record reported that she called herself a "hard sale" on these developments, while also saying the city currently has no affordable housing for residents who can't afford $350,000 homes.
Timber Run Shows Where the Line Sits
McBride Homes' Timber Run proposal shows how this process shapes what buyers will eventually be able to buy. In May 2026, McBride presented a plan for 313 single-family homes on 99 acres off Highway H, on three lot widths of 38, 50 and 70 feet. The Record's September coverage matched the 38-foot lots to McBride's Arbor Series, the 50-foot lots to Bayside and the 70-foot lots to Oakwood. Arbor homes started around 1,020 square feet with two or three bedrooms and a one-car garage. Oakwood homes went up to about 3,184 square feet with three-car garages.
By September, the plan had dropped to 234 lots. McBride associate general counsel Katie Peroutka explained the change to the aldermen, according to the Warren County Record: "it was a beautiful plan, we loved it, but it just didn't fit within the limitations of the current zoning code." The revised plan keeps all three lot widths and leaves 74 acres of the roughly 120-acre site as open space and common ground maintained by a homeowners association. It also adds a pavilion, pickleball courts and a playground. Peroutka estimated prices from upwards of $200,000 to more than $400,000.
That cut removed 79 lots, and the reason McBride gave was the zoning code. The process is still underway. The September 24 aldermen agenda included two bills to annex the parcels, and the outcome of that vote hasn't been confirmed in what we reviewed. The city has since posted public notice of rezoning hearings on McBride Land Growth's petition covering about 121 acres west of Auburn Meadows. The Planning and Zoning Commission meets Monday, October 19, 2026, at 6:00 p.m., and the Board of Aldermen meets Thursday, October 22, at 6:30 p.m. Both hearings are at City Hall, 636 Westwoods Road.
What the Price Points Look Like Next to St. Charles County
Wright City's housing page lists active communities including Alder Creek by Houston Homes, The Shire by Myers Select Homes, Serenity Woods by Fischer Homes and Peruque Creek Manor by Ivie League Homes. Builder base pricing for this month, October 2026, includes:
- Serenity Woods: homes from $299,900, townhomes from $334,900 and the Designer Collection from $353,900.
- The Shire: base plans from $295,000 to $330,000.
- Timber Run, if approved: about $200,000s to $400,000-plus, according to McBride's September presentation.
These are builder base prices. Sale prices and upgrades will differ. For comparison, the median sale price for a detached home in St. Charles County was $389,950 in August 2026, based on 432 closed sales, with 25 days on market and 2.9 months of supply, according to the St. Charles REALTORS August 2026 report. The September 2026 median listing price in FRED's St. Charles County series was $417,675.
The listed starting prices in Serenity Woods and The Shire come in roughly $35,000 to $95,000 below the St. Charles County detached median, while Timber Run's top tier would land above it. The smallest-lot product, which is the closest to the mayor's concern about homes under $350,000, depends most on the zoning code. Arbor-style 38-foot lots are exactly the kind of density the PDA rules restrict. We couldn't find reliable Warren County or ZIP-level sales figures for recent months, so this comparison uses builder base prices against county sales data.
Costs Beyond the Base Price
Three costs fall outside the base price.
Sewer connection and service. Before a home connects, the system-development fee and any lot surcharge described above are paid. Owners without a water meter are billed a flat $60.80 a month, based on 5,913 gallons. Ask the builder whether these fees are included in the price.
HOA-maintained common ground. Open-space requirements of 15 to 40 percent, and Timber Run's 62 percent, mean more land maintained by a homeowners association. HOA dues and the association's covenants belong in any comparison between communities.
I-70 construction through 2028. MoDOT's $600 million Warrenton–Wentzville project adds a third lane in each direction and upgrades interchanges and outer roads in Warrenton, Wright City and Foristell. Construction began in 2025, and completion is targeted for late 2028. MoDOT aims to keep two lanes open in each direction during peak travel but hasn't published estimated commute-time savings.
A Few Questions We Hear
Does the new sewer plant mean more homes will be built quickly? It means capacity is available. The engineers say the plant can serve residential growth without new infrastructure in the near term. How many lots actually get approved, and on what lot widths, depends on PDA zoning decisions made project by project.
Can buyers or residents weigh in on Timber Run? Yes. The October 19 and October 22, 2026 hearings are public hearings held to take public comment on McBride Land Growth's rezoning petition.
Is Alder Creek still a lower-priced option? Alder Creek launched in March 2024 with base prices advertised in the upper $200,000s. That figure is more than two years old, so check current pricing directly with the builder.
