Rezoning and Development: The 751 South Project in Durham, NC

By Stephanie Xu  DP_XuStephanie


A key debate during North Carolina’s 2012 election cycle revolved around the proposed development of 164 acres in southwest Durham County, an area now widely referred to as 751 South.  The development called into question zoning practices and decisions, as the Durham Planning Commission finally approved 751 South to be rezoned from its former Rural Residential designation to a Low-Medium Density Residential designation.  Yet even as Southern Durham Development (SDD), the company spearheading the project, moves forward with its plans, environmental activists and local community leaders have spoken up against the development, citing an irreversible environmental impact, including damage to Jordan Lake and its aquifer.

Amidst the political debate, this paper seeks to examine whether or not the 751 development will be beneficial to Durham using economic analyses.  We first review the origins of zoning policies to gain a better understanding of the sensitivity of rezoning.  Then, we look more deeply into 751 South and the research that has been conducted about the project, including an independent economic impact analysis and a cost-benefit analysis by Durham County.  From the data available, 751 South is a viable and necessary development that will bring a great deal of benefits to Durham County, ranging from job creation to privately-funded highway improvements.

Literature Review

The practice of zoning as a method of urban planning and land use regulation has been surrounded by equity and segregation debates over the past few decades.  A wide body of literature about the topic exists, with a range of focuses, from its early implementation in the early 1900s to its efficiency to its effect upon race and class segregation.  This paper examines the history and progression of zoning practices and policies, as they are crucial to understanding the associated controversies.  We then look into the impact of zoning upon income distribution and equity, first through a more dated but resourceful paper by Fernandez and Rogerson (1997), and then through a 2006 paper by Calabrese, Epple, and Romano.  Lastly, we explore literature concerning the relationship between zoning laws and public health initiatives.

Fischel (2004) offered a comprehensive overview of zoning from its early 1900s origins to modern day policy reforms to address the exclusionary products of such regulations.  Fischel posited that zoning was not a necessary practice until the advent of buses and trucks that allowed businesses to locate farther from streetcar tracks and stations.  Until then, workers were able to buy houses in the suburbs without fear of encroaching business.  However, companies’ newfound capability to transport resources threatened the residential environment that workers found so valuable.  Thus, zoning was the only way to give homeowners security and assurance that their neighboring land wouldn’t become a noisy business district.  Several decades later, the problem was exacerbated by a sudden increase in highway construction in the 1960s.  Firms could now move out of high-density urban areas even more easily.  Failing or struggling cities and suburbs welcomed the influx of businesses for the accompanying fiscal benefits.  Meanwhile, only well-off communities could afford to keep businesses out.  Fischel argued that it was in this environment that income distribution began to play such a strong role.  In this paper, he sought to find a way to keep home values stable, as zoning was initially created to accomplish, without causing the exclusion with which we are faced today.  To resolve this, he proposed selective home equity insurance, despite his acknowledgement of the administrative problems and risks of moral hazard and adverse selection.

Fernandez and Rogerson (1997) and Calabrese et al. (2006) investigated the impact of zoning upon equity, but differed in their approaches in a critical way.  Both used a two-community model with two different income distributions.  Both also made a point of stratification as a natural occurrence, with or without zoning laws.  But the former required in their model that individuals committed to one community or another before any voting took place, and before they bought any property.  Calabrese et al., on the other hand, based their argument upon the Tiebout rationale that people could “vote with their feet” and choose to reside in towns that align with their personal preferences.

Thus they arrived at different conclusions.  Fernandez and Rogerson found that in general, zoning made the richest better off and the poorest worse off, but left a great deal of ambiguity about those in the middle.  Poor individuals who moved from a more affluent community to a lesser one because of zoning policies tended to be better off, while individuals who move to a richer community tend to be worse off.  Calabrese et al. finds an overall increase in efficiency and welfare as a result of zoning, due to their assumptions under the Tiebout model.  They conclude that because residents can move after a community votes on tax rates and local public goods, “aggregate welfare gains arise from better Tiebout matching of preferences to levels of public-good provision” (Calabrese et al. 2006, 4).  Comparing these two scholarly works highlights a decisive factor in zoning theory: that the order in which individuals vote on taxes and public goods, buy property, and choose their community affects the predictions of the ensuing welfare gains or losses.

751 South: Background

Until July 2012, the 751 South region was designated as Rural Residential, which permits four or fewer units per acre of land.  Since the Durham Planning Commission approved the rezoning application by a vote of 8-5 in favor, 751 South is now a Low-Medium Density Residential area and is allowed anywhere from four to eight units per acre of land.

SDD’s plan for the development allocates 300,000 square feet to retail space, 300,000 square feet to office space, 645 apartments, 358 condominiums, 170 townhomes, and 107 single-family houses.  Their plan also includes a 26-acre donation to Durham to build a new elementary or middle school, a new fire department, and a new sheriff’s office.  Finally, SDD has committed to investing the full $6 million needed to improve Highway 751 to expand its capacity and relieve congestion in the area.


751 South: Economic Analysis

The economic impact of the 751 project come in two phases: the construction phase and the permanent operating phase.  Benefits, as outlined by the ERA Economic Impact Analysis, come in many forms, the most significant being in job creation and increased property and sales tax revenue.  Other benefits include SDD’s full funding of the highway renovations and planned donation of 26 acres of land for the purpose of constructing a new public school, and new sites for the fire and police departments.  In total, the value of these contributions exceeds $11.4 million, saving the expense of taxpayer money.  The costs that have been examined include the costs to construct, the cost to equip and staff new fire and police departments, and other operating costs of the new landscape.  Overall, without any reliable data on environmental costs, the benefits to developing the 751 South project exceed the costs by a tremendous amount.

Phase 1: Construction

This building phase of the 751 South project brings changes in three components: direct, indirect, and induced impacts.  Direct impacts refer to the initial changes in industries; indirect impacts refer to changes in inter-industry transactions as demand grows; and finally, induced impacts refer to changes in local spending that result from the changes in the industry sectors.  Intuitively, any development dollars spent and re-spent in Durham County will generate additional income for both companies and their employees as money circulates through a cycle of spending.  ERA acknowledges that there will be some leakages, so this multiplier effect will not be entirely contained within Durham County, but overall the benefits are significant.  Figure 1 breaks down the impacts into three construction phases over ten years, noting the three types of effects upon output, employment, and labor outcome.

Figure 1



ERA has predicted that the direct $414.5 million investment in the project will bring an additional $107.4 million in indirect output and $44.5 million in induced output.  The project is also set to create an estimated 2,419 jobs purely for the development of the site as well as another 1,333 jobs in indirect and induced impacts.  In turn, the job creation results in an increase in labor income in Durham County totaling $166.9 million during the ten-year construction phase

Phase 2: Permanent Operations

The economic impact of the operating activities of retail, office, and consumer spenders is permanent and proves more substantial than the Phase 1 impacts.  The benefits can be broken down into jobs and income, household spending, and tax revenue.  First, using data from the American Planning Association, the new retail and office buildings will house 1,050 new professional office jobs and 683 new retail jobs.  Additionally, the new occupants who will occupy the housing at 751 South will create demand for 714 other jobs for a total of 2,980 new jobs at build-out with an estimated annual labor income of $154.2 million.  Figure 2 provides an exact breakdown of the predicted permanent jobs, which range from construction positions to legal personnel.

Figure 2


Second, 751 South is predicted to house 1,280 new households with a total estimated disposable income of over $98.9 million that will contribute to the new industries and businesses in the area.

Finally, the new development is forecast to bring in about $5.7 million in annual property taxes to Durham and additional revenue in sales taxes.  Data based upon local experience and internal market research examined similar communities such as Colvard Farms and Meadowmont and yielded estimates of $3.2 million for Durham County with an additional $2.4 million for the city if the project area is annexed.


The two economic analyses provided suggest that development in full of SDD’s project for 751 South would be the appropriate policy decision, but fail to acknowledge any environmental impact research that may reduce the perceived benefits of the development.  The economic impact analysis by ERA explores the various benefits that will come from 751 South, ranging from sales and property tax revenues to thousands of permanent jobs to privately-donated land for Durham Public Schools, the Fire Department, and the Police Department.  The cost-benefit analysis by BMS demonstrates that full completion of SDD’s proposal would bring profits sooner than any alternative scenario.  Intuitively, completion of only 48.1% or 21.9% of the project yields slower returns and fewer returns for a lower investment.

The policy question comes down to a balance between environmental risks of developing 751 South and other needs that 751 South would help fulfill for Durham.  While maintaining the status quo would eliminate the environmental concerns, this option leaves Durham with many of its problems unsolved.  Overcrowding in Durham Public Schools will remain an issue, as will the traffic congestion along the 751 and NC-54-I-40 corridors.  While the existing economic studies have revealed a number of economic benefits that would accompany the 751 South project, there has yet to be conducted an official environmental impact assessment that would lend credence to the environmental objections to it.  Without such evidence, a fully informed policy choice cannot be formed.

  1. Stephanie,

    This is a great paper! Your choice of topic is very interesting and relevant. I know from interning in New York City that zoning is crucial to the development of a city and that it can predict the trajectory of a city’s growth. In addition, your literature review on the two models for zoning are well explained and thorough.

    Although this is outside the scope of your paper, it would be interesting to know the general trends in zoning in Durham beyond the 751 South Project and some demographic details. The 751 South Project seems like an indicator that Durham is expanding predominantly in housing. I would imagine as infrastructure improves, more families will be moving to the suburbs of Durham and smaller communities will be built. Are these residents mostly in the same income bracket or race? That would be a great topic for further research.

    After reading your paper, another area I would like to know more about is environmental policy in Durham and the status of nature preservation in light of suburbanization. Is the problem at the 751 South Project unique to that area because of the aquifer and Jordan Lake or is it something that most rezoning areas have to deal with?

    Finally, it’d be great to understand better how Durham county conducted the cost-benefit analysis and how they reached these specific numbers.

    Overall, I really enjoyed reading your paper. Thanks!

  2. Great paper!

    Do you have any comment about the impact this project is going to have on property values in Southpoint region?
