Seagoville is growing fast. Thousands of new homes are planned across two major developments, Stonehaven and Santorini.
That growth raises a simple question. Who is actually paying for the roads, water lines, sewers and drainage those new homes require?
The answer is not a simple yes or no. City records show a mix of private developer spending, resident assessments and public incentives.
How A Public Improvement District Works
Seagoville calls this financing tool a Public Improvement District, or PID. It matches infrastructure costs to the people who directly benefit from them.
Instead of billing the whole city, assessments fall only on property inside the district. Those assessments can stay attached to a lot even after the original developer sells it.
That distinction matters most for future homeowners. They can inherit annual assessment payments once they buy a home inside the district.
Stonehaven By The Numbers
Stonehaven covers about 247 acres. Meritage Homes of Texas originally developed the property, and the City Council approved the development agreement in September 2021.
Major Improvements, Privately Funded
| Category | Cost |
|---|---|
| Streets | $4.65 Million |
| Sanitary Sewer | $6.94 Million |
| Storm Drainage | $2.07 Million |
| Water | $1.91 Million |
| Soft Costs | $1.92 Million |
| Total | $17.49 Million |
Another $16.55 million covered other private improvements. That includes additional infrastructure in these categories:
Improvement Area No. 1, PID Financed
| Category | Cost |
|---|---|
| Streets | $4.83 Million |
| Sanitary Sewer | $1.17 Million |
| Storm Drainage | $1.38 Million |
| Water | $1.36 Million |
| Soft Costs | $873,500 |
| Total With Bond And Admin Costs | $10.82 Million |
The developer agreed to improve Lasater Road and Stark Road during the first phase. Simonds Road improvements followed once development reached that section.
Stonehaven’s developer also built the offsite sewer main that serves the neighborhood and nearby areas. The same developer extended water lines connecting Stonehaven to the city system.
Santorini By The Numbers
Santorini is Seagoville’s larger project. The original development agreement covers about 591.8 acres, and the active PID applies to about 528.1 acres of that land.
Seagoville Laguna Azure LLC is developing the property. The 2024 Service and Assessment Plan set the framework for its financing.
Two smaller pieces round out the plan. About $3.62 million is tied to property that is not assessed, and about $201,683 covers infrastructure oversizing.
Improvement Area No. 1 Breakdown
| Category | Original Cost | PID Eligible |
|---|---|---|
| Roads | $4.25 Million | $3.77 Million |
| Water | $1.92 Million | $1.70 Million |
| Sanitary Sewer | $1.35 Million | $1.20 Million |
| Storm Sewer | $3.36 Million | $2.98 Million |
Major road improvements added another $2.99 million, split between Improvement Area No. 1 and the Major Improvement Area.
Water infrastructure at Santorini covers a full network. So does the sanitary sewer and storm systems.
Two Extra Layers Of Public Support
Seagoville created Tax Increment Reinvestment Zone No. 1 for the Santorini area. Under a TIRZ, new property tax revenue generated inside the zone can be committed to project costs instead of flowing straight into the general fund.
Santorini’s financing documents let eligible TIRZ revenue offset part of certain PID assessment payments. That means new tax growth inside Santorini can help pay for the development’s own infrastructure.
The city also approved a Chapter 380 agreement for building materials. Seagoville will rebate half of the city’s one cent general fund use tax revenue tied to qualifying Santorini building material purchases, for up to 20 years.
Two Developments, Two Different Deals
| Category | Stonehaven | Santorini |
|---|---|---|
| Total Project Cost | $44.85 Million | $42.55 Million |
| Privately Funded Or Developer Share | $34.03 Million (76%) | $2.93 Million (7%) |
| PID Financed Share | $10.82 Million (24%) | $35.79 Million (84%) |
| Added Public Incentives | None Identified | TIRZ Credit Plus Sales Tax Sharing |
Who Pays For Drainage And Roads
Both developments carry heavy responsibility for storm drainage. Stonehaven’s original schedule included millions in both private and PID financed drainage work.
Santorini’s PID package includes multimillion dollar storm sewer and drainage costs too. City rules also let Seagoville require detention ponds so new development does not overload existing drainage systems.
Growth still increases traffic on roads across the whole city. The reviewed agreements do not require developers to pay for every future signal or intersection tied to citywide growth.
That broader cost can eventually land on the city, the county or state transportation programs. It is not automatically billed back to either subdivision.
The Gap: Police And Fire
The financing documents are detailed for physical infrastructure. They cover these categories directly:
They do not include a comparable plan for police staffing. New homes do not come with a dedicated payment for added patrol officers, vehicles or police facilities.
The same gap applies to fire protection. Developers build hydrants and water lines needed to fight fires inside their own subdivisions, but that is different from funding the items below:
Seagoville is now planning a new fire station near Kaufman Street and Hall Street. The city may issue up to $7.15 million in certificates of obligation for that project, and that debt belongs to the city rather than to either PID.
Taylor Farms Is A Different Kind Of Deal
The city also holds agreements tied to Taylor Farms. Those cover reimbursement for staff and consultant costs during early project review.
One agreement began with a $20,000 deposit from the developer. The city required that deposit to be topped off once it fell to $5,000.
Public records reviewed for this story do not show Taylor Farms as an active residential PID like Stonehaven or Santorini. It should not be grouped with those two projects until a final development agreement is confirmed.
So Are Existing Homeowners Subsidizing Growth?
Not directly, for most subdivision infrastructure. But the answer shifts once broader city capacity enters the picture.
- Streets, water and sewer costs are largely covered by developers and PID assessments inside the developments.
- Police staffing, fire staffing and citywide road capacity are not covered by either development agreement.
- New tax revenue from growth is expected to help close that gap over time.
