A private developer purchased a property to build a rail-served industrial park with specialized grain-handling facilities, supporting regional economic development goals, but the site lacked the necessary highway access. A partnership between a county government and a private developer allowed the county to receive a low-interest loan through the State DOT infrastructure loan program for local governments to upgrade a gravel road to a concrete industrial access road. The loan is repaid by the tax increment from a TIF district, with risk to the county mitigated by a guarantee from the private developer to meet debt service obligations in years when the increase in property values does not generate sufficient tax increment to meet loan payments.

Key Takeaways

  • The project was well suited to value capture because:
    • There was a clear business case and local benefits for the rail industrial park (the element of the project that created value to capture) and would not have occurred without the TIF.
    • There was an easily defined beneficiary (the developer and property owner) who was willing to dedicate a portion of project benefits to pay for the infrastructure necessary to make it possible.
    • The project had negligible (if any) negative impact on others.
    • The value of the benefits was easily quantifiable, and both the county and the developer agreed on this value.
  • TIF worked to capture the benefits because:
    • It was already widely used throughout the state for similar projects and had the support of the governor, head of the State DOT, and eventually the county elected officials (politically acceptable).
    • It was relatively easy to fulfill the administrative requirements to establish the TIF and easy to administer and had low transaction costs (practical).
    • It did not displace population or divert resources from other public projects (equitable).
    • The innovation of the guarantor agreement between the county and the developer (1) appropriately protected the county from the risk early in the project when property values did not produce enough increment to cover debt service, (2) provided the developer with a lower cost of capital than could be obtained in the private market, and (3) allowed the developer to apply a portion of property tax payments to debt service during a period of significant construction costs and increase in property taxes but before commensurate increases in revenues from operations would occur.

Description of the Project

In 2010, the Dakota Plains Ag Center, LLC purchased a 192-acre parcel of land in Yankton County, South Dakota, with plans to establish a rail industrial park with a $40 million grain terminal. The property is served by the state-owned Dakota Southern Railway and Burlington Northern Santa Fe north-south rail lines and is approximately 3.3 miles from South Dakota Highway 50. However, the roadways between the state highway and the project site were gravel, unable to accommodate heavy truck traffic, and not federal-aid eligible.1

Yankton County is largely rural, with a 2019 population of approximately 22,720 concentrated in the City of Yankton (2019 population of 14,570),2 approximately 8 miles southeast of the Dakota Plains Ag Center site. Sioux Falls is approximately 80 miles northeast, Omaha, NE, is approximately 170 miles southeast, Pierre is 230 miles west, and Rapid City is 350 miles west.

According to the 2017 US Census of agriculture, farms make up approximately 97% of the county’s land area (329,607 acres), and about 70% of croplands produce corn, soybeans, forage, and wheat–products that rely on rail transportation for distribution. Yankton County farms produced over $105.8 million in sales of grains and related products in 2017, more than 65% of the county’s total agricultural sales and nearly a 50% increase over the county’s grain sales in 2007.3 All this illustrates that the rail industrial park serves an important and growing industry in the region and provides substantial benefits.

To accommodate the anticipated volume of heavy truck traffic, a concrete industrial service road was proposed for County Road 210/Deer Boulevard/437th Avenue (Between SD Highway 50 and 307th Street), 307th Street (between 436th and 437th Avenues), and a portion of 436th Avenue (from 307th Street to the rail-industrial park entrance). The 4 miles of improvements consist of 3.2 miles of Portland concrete and 0.8 miles of gravel with a total cost of $6.2 million (in 2015 $).4 Figure 1 illustrates the location and extent of the service road and rail industrial park (labeled “Grain Terminal Site”). Figure 2 shows available development sites made accessible by the service road.

To provide a sense of scale of the total project cost relative to county funds: The county’s total general fund budget for 2021 is $12.3 million and the county’s 2021 road and bridge fund is $4.9 million. Typically, highway projects in South Dakota are funded through the State Infrastructure Bank. However, in this case, the roadways needing improvement are not state roadways and not on the federal-aid highway system and were therefore ineligible for funds through state or federal grant or loan programs.

The property owner was motivated to construct the Dakota Plains Ag Center facility in this location because it had several advantages over other potential locations, yet the cost of private financing for the road was prohibitive. In addition to the purchase of the land ($3.975 million), site prep and engineering and rail facilities ($4.9 million), and costs of construction for the facility, the developer also assumed significant infrastructure costs associated with the establishment of an electrical substation and water infrastructure to serve the site and surrounding areas ($800,000).5

The industrial service road provides significant benefit to the property owner by enabling development of a rail industrial park that generates far more economic activity than it did as an agricultural parcel, greatly increasing the value of that property. The roadway will also increase property values along the improved roadway for all parcels that gain access to the state highway. However, the service road also serves a public purpose in that it provides a connection from a state highway to a rail line that serves a key industry in the surrounding community. Benefits and beneficiaries are summarized in Table 1.

Value Capture Set-Up and Implementation

Dakota Plains Ag Center, represented by a financial consultant experienced with tax increment financing,6 proposed that Yankton County obtain a State Highway Fund Loan for Local Governments from South Dakota Department of Transportation (these funds are available only to government entities, not private companies), repaid by tax revenues through creation of a TIF district. Table 2 presents a summary of key loan details.7

To comply with the terms of the loan, Dakota Plains signed a developer’s agreement with Yankton County establishing Yankton County as a conduit borrower. Under South Dakota law, this constitutes a bond that obligates the County to act as a conduit of future tax increment revenues. The county is to pass on increment revenue in excess of loan payments to Dakota Plains, while Dakota Plains is the guarantor of the debt and liable in the event tax increment revenue is insufficient to cover debt service. Loan payments are made by the county and tracked in the county budget under the Napa Junction TIF Debt Service Fund line item. In years where TIF revenue falls short of the loan payment amount, Dakota Plains must pay the County the amount of the shortfall.

Although TIFs were not new to South Dakota or Yankton County, this was the first time a TIF was used to support a State Highway Fund Loan for infrastructure development.

This arrangement allowed Dakota Plains to access a lower interest rate than it could obtain as a private company and enabled the county to apply a portion of the property tax levy generated by the investment to debt service. The rail industrial park supports the county’s economic development with jobs and economic activity, and at the end of the TIF period, will generate increased property tax revenues for the county and school budgets.

TIF revenues are applied to construction cost only. The roads are owned and maintained by Yankton County.

South Dakota Codified Law Chapter 11-9 requires that the planning commission must adopt a project plan for the district and submit it to the governing body. The governing body must approve the project plan to establish the district. For the Napa Junction Industrial Park TIF District, Dakota Plains Ag Center retained a consultant with experience creating TIF districts in South Dakota to work with county officials to produce the project plan (Tax Incremental District, Yankton County, Tax Increment Project Plan, June 2015).

The TIF district boundaries originally proposed by Dakota Plains encompassed four parcels (the largest of which has since been subdivided into five parcels). By acres, about half of the land was owned by Dakota Plains (some of which has since been sold), a third was owned by another private party, and the balance was under other ownership. These boundaries were accepted by the County Commission.

The commission also accepted Dakota Plains’ proposed duration of 20 years,8 or until the TIF project cost of $7,725,000 is reached (whichever comes first). This is the maximum duration allowed under South Dakota law and is designed to allow ample time for property values to increase enough for total tax increment generated to meet the TIF project cost amount. If the amount of tax increment generated reaches the TIF project cost before 20 years, the TIF is dissolved early. Conversely, the TIF district will dissolve in year 20 regardless of whether total increment has reached total project cost. Under the agreement between the county and the developer, the developer assumed this risk.

Table 3 presents TIF-eligible9 project cost estimates from the project plan. The developer was responsible for nearly $8.9 million in other costs that were not covered by the TIF. The total amount of TIF requested, $7.7 million, is greater than the $6 million loan, because it includes funds for supporting electrical and water infrastructure necessary for the industrial park, but not eligible for SDDOT highway loan funds. After the loan is repaid in year 10, the tax increment accrues to the developer for the remainder of the TIF period, up to the amount of the TIF project cost.

Though the Napa Junction Rail Industrial Park and access road project met the eligibility criteria for creation of a TIF, it did not initially have the support of the Yankton County Commission. However, a new slate of Commissioners was elected in 2014, and the TIF district was approved in 2015. South Dakota Governor Dennis Daugaard and Secretary of Transportation Darin Bergquist were supportive of the project.

TIFs in South Dakota

The South Dakota legislature created statutory authority for TIF in 1978 with SB 17. The original enabling legislation was available only to municipali¬ties, required a finding that not less than 25% of property in the TIF district was blighted, and limited TIF revenues to funding only “costs of public works or improvements.” The enabling legislation has been expanded and refined over the years, with counties gaining authorization to use TIF in 1991 (SB 1174), and elimination of the blight requirement in 2011 (SB 90), as well as changes to the way TIF revenue streams were treated in 1996, 2004, 2016, and 2018.

TIF is used widely in South Dakota. The 2020 Tax Increment Financing Annual Report produced by the State Department of Revenue states that there have been 369 TIF districts in the state since 1978, with 193 active. The state laws governing creation of TIF districts are laid out in South Dakota Codified Law Chapter 11-9.

TIF was not unknown in Yankton County at the time the Dakota Plains Ag Center and the county were trying to determine a way to pay for the road. The City of Yankton had established the Fox Run Tax Increment District in 1989 to complete a large, high-profile mixed-use project recognized for its role in revital¬izing that area of the city. And in 2015, the city was in the process of establishing the Westbrook Estates TIF to fund an affordable housing development. Neigh¬boring counties had also used TIF. Turner County used a TIF in 2006 to support development of an ethanol plant, Lincoln County used TIF in 2011 to support development of an industrial park and again in 2016 to support new affordable housing, Hutchinson County used TIF in 2012 for a project in Parkston, and Douglas County established a TIF in 2014 to support public infrastructure.

The Napa Junction Rail Park TIF is the first time in South Dakota that a TIF was used to borrow from the State DOT’s Highway Fund Loan for Local Governments.

TIF Financial Details and Status

Before creation of the TIF, the 192-acre area was assessed at agricultural tax rates. The 2015 property tax bill for TIF district parcels, based on 2014 (pre-investment) property values, was just $3,400 on an assessed value of approximately $348,100.10 Figure 3 presents TIF district actual assessed value for 2015-2020 (from property tax records) and an estimate of assessed value for 2021 based on the completion of the Dakota Protein facility currently under construction.

By 2016, the assessed value increased by more than 750%, to $3.2 million, generating property taxes of $49,600. Another significant jump occurred in 2018 when the value increased to nearly $30 million, generating property taxes of nearly $438,000. Executive Director of Yankton Area Progressive Growth (the regional economic development organization), Nancy Wenande, stated that in 2018, Dakota Plains Ag Center, LLC property–just one of nine parcels that comprise the TIF district–had the highest property value in Yankton County.11 For reference, the total countywide property tax base is approximately $2 billion.12 (Assessed value decreased slightly in 2019 due to a countywide decrease in property values.)

Figure 4 presents property taxes levied on TIF district properties 2015-2020 (2020 is an estimate based on applying the 2019 mill rate to the 2020 assessed value reported in tax records). Yankton County collects property taxes in arrears which means that property tax due on the 2020 assessed value will be collected in 2021. The amount shown for 2020 is an estimate made by applying the previous year’s mill rate to the actual 2020 assessed value from county property tax records.

Under the terms of the TIF district, property owners continue to pay property tax based on the property’s full assessed value (shown in Figure 4). The creation of the TIF district changes how the tax collected is allocated. The amount that would have been collected on the equalized base value of the district established when the district was created is allocated to the county General Fund as usual. The amount of tax collected on the “increment”, the amount of property value over the established equalized base value of the district is allocated to the County’s Napa Junction TIF Debt Service Fund.

The TIF district’s assessed value relative to equalized base value–the total current increment–is certified annually by the South Dakota Department of Revenue and reported in its Tax Increment Financing Annual Report (first published in 2016). Figure 5 presents the increment in value, while Figure 6 presents an estimate of tax collected based on the increment based on prevailing property tax rates in each year. The cumulative amount of property tax collected from the increment from the TIF’s inception through 2020 is estimated at $1.4 million. The increment created was insufficient to cover debt service until 2018. Yankton County billed Dakota Plains Ag. Center LLC for shortfalls in 2016 and 2017.

Table 4 presents a comparison of estimated TIF revenues relative to annual debt service payments. As the table illustrates, tax revenue from the increment surpassed debt service beginning in 2018. As the final line of the table shows, the total amount of increment generated through 2021 is not yet sufficient to cover the total amount of debt service to be paid through 2021. Rough calculations suggest that the amount of TIF revenue will not yet exceed debt service by Year 10 when the final loan payment is to be made, but the increment will exceed the total amount paid to debt service by year 14 (2029), and total TIF expenses (including the electrical and water infrastructure costs) will be recouped around Year 16 (2031).13 This would dissolve the TIF district about 4 years ahead of schedule. These estimates are conservative in that they are based only on the existing development (including Dakota Protein, which is under construction). It is reasonable to expect the rail industrial park to attract additional development in the intermediate term, which would accelerate the recouping of expenses estimated here.

Outcomes of Value Capture Application

Economic Development

As a result of completion of the industrial service road and related infrastructure, Dakota Plains Ag. Center, LLC was able to develop a $40 million high-speed grain receiving facility and industrial park with sites available for development. The Dakota Plains Ag. Center Napa Facility, as it is called, employs 10 full time equivalent (FTE) employees with above average wages and an annual payroll of over $1 million.

In addition to the Dakota Plain Ag. Center’s own facility, two other businesses have purchased parcels in the industrial park:

  • Dakota Protein, a grain pellet manufacturer with international sales purchased a 12.3-acre site and is constructing a $15 million pellet grain manufacturing facility in 2021. When complete, the facility is expected to employ an additional 10 FTE employees.
  • Antelope Creek Wildlife & Ponds purchased a 2.2-acre lot to operate a fish and wildlife management business employing 3 FTE employees.

Dakota Plains Ag., which owns the rail industrial park, also does the marketing and sales. The property is advertised with the South Dakota Governor’s Office of Economic Development site selection service ( as well as Yankton Area Yankton Area Progressive Growth, the local economic development agency. Parcels are advertised at $30,000 per acre, which represents a premium over other industrial properties listed in Yankton County, which are advertised for between $15,000 and $20,000 per acre. The availability of accessible local feed supply is inducing further agricultural development.

Though the Napa Junction Census tract is not low income, the rail industrial park became a Qualified Opportunity Zone as contiguous to a low-income census tract in 2016. The opportunity zone designation confers preferential tax treatment for investment in businesses located there.14

Fiscal Impacts

The industrial park creates few demands on county services, so it does not add appreciable costs to the county budget. As in many communities, schools represent the largest budget line item. This project does not add school children to the school system and does not increase the region’s population. As a result, fiscal impacts are limited to the cost of maintaining the road, which is assumed by the County, with a negligible impact on other County services such as public safety (law enforcement), county courts, protective and emergency services, and general public administration. Because of this, diverting property tax increment created by the project does not divert critical resources from the County budget needed to meet the fiscal demands of the new development. Instead, when the TIF expires, the industrial park provides a significant new source of property tax revenue to the county budget.

Other Outcomes

As a result of the successful use of TIF to support a State Highway Funds for Local Governments loan, the South Dakota DOT revised guidelines for the loan program to include economic development potential as a factor for determining whether to award a loan.15 The revised guidelines, which went into effect in 2019, have already contributed to approval of a TIF-supported loan in Lyman County for an industrial service road providing access to a grain shuttle-loading facility constructed using TIGER Grant funds.

Implications for Future Applications of Value Capture

This value-capture implementation was successful for the following reasons:

  • It had a high likelihood of creating property tax revenues in excess of the cost of TIF-funded infrastructure (it made a strong business case).
  • The potential for job creation, economic development, and farmer benefits promoted stakeholder support from elected officials.
  • It imposed virtually no cost to or negative impact on anyone else, which minimized stakeholder opposition.

Creation of this TIF district was relatively uncomplicated for the following reasons:

  • It did not displace population (including vulnerable populations) or housing supply (including affordable housing).
  • It was completed on former agricultural land with no significant environmental concerns.
  • Because it did not attract population, it does not add new fiscal costs to the county budget (nor does it introduce new fiscal costs during the TIF district period when the increment is being used to fund the TIF infrastructure and not available to meet new fiscal costs).
  • It does not create significant equity issues.

Although the use of TIFs in South Dakota to support this type of development is relatively common, the innovation was the agreement between the county and the developer that the county would be the borrower and the developer would be the guarantor in a public-private partnership. This eliminated the risk to the county if property values did not produce enough increment to cover debt service while providing the developer with a lower cost of capital than could be obtained in the private market, as well as the ability to apply a portion of property tax payments to debt service during a period of high construction costs and increased property taxes but before commensurate increases in revenues from operations would occur.

As shown in Table 1, the project creates three sources of value that could be captured, as well as other public benefits of reducing truck freight on state and local roads. Through this TIF, the project captures only the value that accrues to the industrial park’s property owner through the significant increase in that property’s value. It does not capture value that accrues to other landholders whose properties have also gained improved access to the state highway (as well as the rail facility), nor the value of lowered transportation costs that accrues to farmers using the roadway and rail facility to bring their product to market. This limited approach was appropriate for the scale of the project itself and the agricultural nature of the surrounding area. A value capture approach for a more expansive project in an urbanized area (i.e., affecting more property owners, businesses, and residents benefiting from lower transportation costs) might seek to use additional techniques to capture value from these other beneficiaries as well, if the value of the project can be communicated to these other stakeholders to gain their support (or avoid opposition).
