"No immediate demand requiring near-term construction." That is how the June 8, 2026 council work session minutes sum up the council's view of the farmland north of town. Five months earlier, the same area was described as facing "active development pressure from multiple properties" and as "key to unlocking future growth."
That change of view now sits in Polk City's capital plan. If you're thinking about building here, it matters more than any median price. The next new subdivisions on the north side need a trunk sewer the city has pushed into the next decade. Until that pipe exists, new construction in Polk City mostly means the plats that already have sewer. That supply is limited, it is already being divided into lots, and it falls into two price tiers.
Five Months, Two Sewer Plans
At the January 26 work session, City Engineer Travis Thornburgh laid out the North service area at about 7,500 acres. Staff put the North Trunk Sewer's projected 2026 cost at $3.81 million and recommended building it in FY2027. The Northeast trunk would wait until FY29, and the Southeast would stay "developer-driven due to cost constraints." The council generally agreed with putting the North first.
By June the council had changed course. Council members cited concerns about "timing, debt financing, and ensuring a reasonable return on investment." Most did not support building in the coming fiscal year. They asked staff to prioritize "areas with stronger near-term commercial potential" and to prepare a deferral. The amended plan in the August 10, 2026 council packet went further than a one-year delay:
| Trunk sewer | Prior schedule | August 2026 CIP amendment | Listed cost |
|---|---|---|---|
| North | FY2029 in the prior plan; council favored FY2027 in January | FY2031 | $4,732,000 for Segment 1 |
| Northeast | FY2027 | FY2028, to be "revisited next year" | $5,447,000 |
| Southeast | City project | Removed; expected to be built by a developer | Not listed |
The packet's resolution says the amendment was "PASSED AND APPROVED" on August 10, 2026. One detail is unresolved. The staff memo moves the Northeast to FY2028, but the project-by-year summary in the same packet lists it under FY2029. Either way, no new trunk line is scheduled for the next few construction seasons.
Why the Pipe Decides Where Homes Can Go
A trunk sewer is the large main line that new subdivisions connect to. Without one, a developer can own land, draw lots, and win plat approval and still be unable to build houses there.
That has already happened in Polk City. A trunk-sewer study in the city's May 2026 work session packet notes that Seasons Ridge had a preliminary plat on the Schlife property in the Northeast service area but no sewer service. The landowners there had shown interest in developing soon, and the city studied interim options. On the north side, the June engineering update described the North trunk as "the most practical and cost-effective solution" for the Young property and surrounding parcels. Routes along 3rd Street or lift stations would be "significantly more expensive."
The North service area lies east of Big Creek State Park and north of Creekview Estates, the Big Creek Technology Campus, and Big Creek Commons. That is where the city would naturally expand next. It is now on a FY2031 schedule.
There is a cost side too. The 2022 study proposed connection-fee districts that charge future development to recover trunk costs. It estimated about $2,700 per acre in the North district and about $3,000 per acre in the Northeast district. In 2025, city engineering notes said that approach was being reworked to charge by land use instead of by acre. Those numbers were study estimates, not adopted fees. They show how the cost of the next round of infrastructure will eventually reach future lot prices.
What You Can Build on Today
The supply that remains is in subdivisions where streets, water, and sewer are already in or being finished. It falls into two groups that serve different buyers.
Production homes at Creekview Estates. When we checked this fall, D.R. Horton showed four homes for sale in Creekview priced from $359,990 to $408,290. They range from 1,498 to 2,462 square feet with three to five bedrooms, and three more were marked under contract. The plans are ranch and two-story designs, some with finished basements. Standard features listed include white quartz countertops, stainless appliances, electric fireplaces, and smart-home technology. Orton Homes also markets two ranch plans of about 1,500 square feet there. The city accepted Creekview Estates Plat 3 public improvements in August 2026, so more of that phase is moving from construction toward homesites.
Custom lots at Antler Ridge and Monarch Crossing. Here you buy the lot and choose a builder. Builder marketing published in July 2026 lists Antler Ridge and Monarch Crossing lots from roughly $129,000 to $240,000. The same page gives two different starting prices, and it says standard, daylight, and walkout lots were build-ready in summer 2026. Dynasty Homes also names Monarch Crossing, Antler Ridge, and Big Creek Ridge as Polk City communities where it builds custom homes. One city record shows how buyers are using these lots. At the August 17, 2026 Planning and Zoning meeting, an Antler Ridge Plat 3 survey combined four lots into three to make room for larger home designs. Antler Ridge has more room in each lot and fewer lots overall.
Smaller phases add to both groups:
- Four Seasons Polk City Plat 2: MJR Developments submitted construction drawings for 18 lots, with extensions of W. Whitetail Parkway and NW 10th Circle plus sewer and water mains. The city engineer recommended approval, and permits are still required before work begins.
- Sunrise Ridge Plat 1: public improvements were accepted in the August 24, 2026 council packet.
- Big Creek Commons, Big Creek Ridge, and Monarch Crossing: all appear on the city's current development projects page. That page is undated, and its lot totals may not match the lots still for sale.
The Pace Tells You How Long This Supply Lasts
The city's building reports show a steady pace, not a rush. Polk City issued eight new single-family permits in May 2026, two in June, and four in July. That is 14 new houses in three months.
That slow pace supports the council's reasoning. If existing plats are absorbing a handful of homes a month, an expensive trunk line would sit mostly unused for years while the city paid its debt. It also means today's sewered lots, plus the phases still being finished, have to cover new-home demand in Polk City into the early 2030s.
The wider market is not under pressure. According to the Des Moines Area Association of REALTORS August 2026 report, the metro had 1,263 closed sales in August 2026, a median sale price of $319,725, 50 days on market, and 4,702 active listings. Those are metro-wide figures, not Polk City alone. Even so, Creekview's entry homes start about $40,000 above the metro median. In August 2026 buyers had time to compare, but within Polk City the choice of new homesites is narrower than the plat maps suggest.
The Southeast Is the Open Question
Taking the Southeast trunk out of the city plan does not mean it won't get built. It means a developer, not the city, is expected to pay for and build it under a future development agreement. That area is south of Highway 415 and east of Saylorville Lake, and the planned gravity line runs through Antler Ridge.
The August memo does not name the developer. The earlier sewer study recommended a development agreement with Timbercrest Homes for some or all of two sewer segments. Timbercrest's Allure at Saylorville is a 29.61-acre project with proposed townhome, multifamily, and commercial zoning. A 2024 city review required the city and developer to agree on the Highway 415 sewer crossing before preliminary-plat approval. If that agreement moves forward, the next new housing in Polk City may be attached homes in the southeast rather than single-family homes on the north side. That is an inference from the record, not a confirmed plan.
Capacity farther downstream is not the limit for now. Polk City sends wastewater through two lift stations into the regional WRA system. The 2022 study estimated about 20,200 people could be served before downstream WRA upgrades were needed. The holdup is the local trunk lines, not regional treatment.
Questions Buyers Are Asking
Does the deferral affect a lot I'm buying in Antler Ridge or Creekview? Those subdivisions already have public improvements accepted or underway, so the trunk deferral does not change whether they can connect. The deferral affects the farmland beyond them.
Could the North trunk move back up? The Northeast project is set to be "revisited next year," and the council's direction can change, as it did between January and June 2026. Watching council work session agendas is the most direct way to see a change coming.
Where are new-home price ranges published? Builders post them on their own sites and update them often. The figures here were current when we checked this fall and should be confirmed before you compare lots.
Choosing between a Creekview plan and a custom build on an Antler Ridge walkout lot means weighing price, lot size, and the time it takes to build.
