At a time when local governments are struggling financially, two studies — one in Sarasota County, Florida, the other in Asheville, North Carolina — suggest that one of the best fiscal remedies is dense, mixed-use development.
The studies, by Public Interest Projects, a real estate development firm in downtown Asheville, show that on a per-acre basis, sprawling single-use developments such as big-box stores do a poor job of providing governments with needed tax revenue. Dense, mixed-use development, usually downtown or adjacent to transit, is financially much more beneficial.
Peter Katz, director of smart growth/urban planning for Sarasota County, commissioned J. Patrick Whalen Jr. and Joseph Minicozzi of Public Interest Projects to analyze how much property tax is produced per acre by various kinds of development. Looking at specific properties — from high-rise buildings in the City of Sarasota’s downtown to big-box stores and shopping malls across the county — the researchers discovered that dense, mixed-use urban development is far superior.
From a tax revenue-per-acre (versus per lot or per household) perspective, the properties that are typically occupied by retailers like Walmart, Costco, and Sam’s Club turn out to be very disappointing. They generate about $8,350 per acre — “maybe $150 to $200 more per acre per year than single-family houses in the city like mine,” Katz says.
The county’s premier mall, Westfield Southgate, anchored by Macy’s, Dillard’s, and Saks Fifth Avenue, was found to produce almost $22,000 per acre — nearly three times as much as a big-box center. “This is not surprising, given that it’s a higher-quality building in a better, close-in location (actually within the City of Sarasota),” Katz notes.
Yet even a top-of-the-line mall pales in comparison to the per-acre revenue obtainable from dense urban development. A 17-story mixed-use building occupying .75 acres on Main Street downtown generates $1.01 million annually in city and county taxes, according to Katz. That building, completed in May 2007, which has retail in its base, several floors of offices, and then condominiums in the upper levels, produces $1.2 million per acre in county property taxes alone. “It would take about 145 acres of Walmarts — or five of them, to be precise — to equal the contribution of that one downtown building,” says Katz.
“Even a mid-rise mixed-use building — about seven to nine Stories — in the downtown brings in a healthy amount per year, from the mid-$500,000s to just under $800,000,” he says. “Low-rise construction — just two or three stories, with housing or offices over retail — the kind of ‘town center’ redevelopment now replacing many older suburban shopping areas, can bring in around $70-90,000 per acre. The high end of that range is more than four times that of the county’s highest earning mall,” Katz emphasizes.
Similar patterns were found in Asheville and Buncombe County, North Carolina. Per acre, the best generator of county property taxes in the Asheville area was urban residential buildings of six stories or more, says Minicozzi. Ranking below those as tax generators were mixed-use condos of 3 to 4 stories and urban mixed-use buildings of 2 to 4 stories.
Always higher return
“Downtowns achieve a higher rate of return than an acre of suburban development could ever do,” Minicozzi says. The reason is simple: “Once you start getting two stories, you start getting twice as much value.” As buildings go higher while covering much or all of their ground, the revenue escalates.
Minicozzi argues that a municipality should look at tax revenue per acre just as a farmer looks at income per acre: “Urban development produces a valuable yield, like that of a cash crop, while low-density suburban development is the equivalent of growing an acre of grass. By our estimates, suburban development doesn’t even cover the cost of the infrastructure that serves it in a reasonable period of time.”
When land and buildings are included, the suburban Asheville Mall produces taxes of $7,995 per acre for the county. That’s slightly more than the yield from one- and two-story buildings in the central business district. But keep in mind that many downtown buildings surpass the mall in tax contributions. Two- to four-story apartment buildings downtown generate more than twice as much as the mall: $18,109 per acre.
The Asheville area’s most productive development, in terms of paying for public services, is mixed-use and in a dense, walkable area. Three- to four-story, downtown mixed-use buildings containing condo units generate $44,887 — more than five times as much per acre as the mall. “A moderate high-rise, mixed-use development that was proposed in the downtown could have generated as much local property taxes as the 73-acre Asheville Mall plus the Asheville Walmart, plus the new 60-acre big-box power center near the airport,” Minicozzi says. (The downtown building was approved and is awaiting financing.)
What’s best is downtown mixed-use/condo construction that rises six stories or more. It produces more than $250,000 per acre in taxes to the county alone. Minicozzi believes the results are similar in other communities. “We feel that Asheville is a model for the entire country,” he says.
Many states distribute a portion of their sales tax to the localities in which it was collected. This has encouraged some localities to pursue big-box and other sprawling retail projects no matter how bad an impact they exert on urban form.
Analysis reveals that the sales tax benefit is often smaller than local officials think. When a dollar of sales tax is collected in Asheville, the state gets a major portion, Minicozzi observes. Some of what’s returned is distributed throughout the county. Ultimately only 27 cents reaches Asheville itself.
It’s estimated that an average Walmart sells $77 million of merchandise per year. That volume would result in $1.6 million in retail sales tax being returned to Asheville. This amounts to about $47,500 of sales tax revenue per acre, Minicozzi points out. “Couple this with the $3,300 in property taxes per acre for the City, and we’re looking at only about $51,000 per acre in total taxes for Asheville.”
“When you compare that to the $248,000 per acre that the City gets for property taxes alone for 6-story mixed-use development downtown, the case is clear as to which form of development returns more to our tax base,” Minicozzi says.
Furthermore, compact development costs less for roads, water, sewer, and other necessary infrastructure. A 1989 study by the Florida Department of Community Affairs found that the infrastructure cost per “compact” housing unit in downtow n was $9,252, versus between $15,316 and $23,960 for more “scattered” suburban style housing units (amounts adjusted to today’s dollars).
Minicozzi continues: “When one does the math on those costs against the tax revenues we were seeing in Sarasota County, it took a suburban multifamily housing development 42 years to pay off its infrastructure, while a mixed-use downtown tower (calculated for its residential portions only) was paying off its infrastructure costs in three years.”
Lessons learned
Katz concludes: “A simple change of metric — from revenue per lot or unit or household to revenue per acre — makes a huge difference in assessing the fiscal impacts of alternative planning scenarios. What’s most surprising to me is that it’s taken planners so long to ask such questions and begin looking at the data in this way. Given the lean times we’re in, I suspect this will increasingly be part of the conversation in many municipalities.”
The findings from the two studies, Katz says, “reinforce a concept advanced in the mid- to late 1800s by Henry George: the idea that land is our most precious shared resource. Since land is the raw material from which government derives most of its working capital in the form of property taxes, it makes sense to evaluate different forms of development in terms of their potential for revenue return.”
“For years, I’ve been trying to make this connection,” says Sarasota County Administrator Jim Ley, who runs the county government. “As long as the economy and the tax base continued to grow,” many found it easy to ignore the financial downside of sprawl, Ley says. Now, with the economy and tax base in trouble, Ley thinks Katz’s study will help lead the county toward a more rational attitude on development.
“A blinding flash of the obvious” — as Ley characterizes the study — can make a difference.
