Learning from First Ring Suburbs

A first ring suburb is an incorporated city surrounded by other incorporated cities that prevent its further expansion. In some cases, the enclosure was considered protection from further change that could damage its desirable quality of life, but lack of change can be a failure to adapt. It also appears that in some cases, increases in municipal expense were assumed to be met with equal or greater increases in municipal revenue, but growth of the two has often proven unequal.

FIRST RING SUBURBS

The relatively inflexible nature of a city’s buildings and infrastructure has left growth through annexation for new revenue a common expedient for all but isolated, “first ring” suburbs, but this new money has not always been adequate to meet increasing expense over time, which has stimulated more annexation referred to as “sprawl” that will appear like a Ponzi scheme over time. 

A first ring suburb may be a blessing in disguise, since it must learn to adapt to change without increasing the consumption of agriculture and its source of life, the Natural Domain in a guessing game of growth without an adaptive solution to the planet’s unwritten Law of Limits.

The shared value of land becomes obvious in a first ring suburb because it cannot annex more land to adjust the allocation of activity and intensity producing its revenue. 

Annexation is prompted when the average revenue produced per taxable acre by a city’s past allocation of activity and intensity is less than its current and projected total operating, maintenance, improvement, and debt service expense per taxable acre. This stimulates budget reductions and intense debate over “essential” services, income tax increases, and layoffs when annexation is not an available expedient. At this point, the politically charged terms rezoning, redevelopment, and eminent domain enter the picture.

Unfortunately, a city may lack the data science, shelter capacity evaluation, activity allocation, and performance monitoring needed to assess the existing and potential revenue productivity of every taxable parcel within its boundaries. This makes comparison of revenue per acre with its expense per acre a guessing game. It will always be an uncertain prediction, but its accuracy can be significantly improved with the knowledge we have but have not correlated.

Correlation will require public data cooperation and the evaluation of shelter capacity, intensity, and activity allocation throughout a city. This correlation can reveal the revenue performance of a city’s land area per acre with its average annual expense per acre as a prelude to an on-going economic development strategy. This strategy will also need monitoring that only data science and geographic information systems can provide when correlated with shelter capacity evaluation and urban design leadership direction.

I have written about the mathematics of shelter capacity evaluation and the leadership potential of urban design equations, data science, and geographic systems on many occasions. First ring suburbs simply represent a unique opportunity to study the correlation and leadership decisions required to shelter the activities of increasing populations within self-sustaining, limited geographic areas that do not sprawl to consume their source of life -- while ensuring their quality of life with shelter capacity, intensity, and context leadership decisions we have yet to define with a correlated urban design leadership language.

GROWTH CORRIDORS

I would like to make one final comment. After seeing decline in first ring suburbs, I believed that a city had no option but to ensure access to unincorporated land it could annex for new revenue as its expenses increased. I didn’t realize at the time that the revenue yield from the annexation could become inadequate as the expense of aging infrastructure increased; that a city had difficulty comparing its annual revenue per parcel of block with its total annual expense per taxable acre; or that annexation represented a Ponzi scheme that could exhaust limited resources.

In other words, performance evaluation was a broad-brush exercise in hindsight at the end of the budget year. This problem became increasingly obvious in first ring bedroom suburbs that exported their income tax revenue to surrounding employment centers and shared their real estate tax revenue with other local institutions. It appeared to be a recipe for decline.

Cities needed a better method of predicting and monitoring the revenue potential of land within their boundaries. This may be a relatively new argument because the value of land has been related to its profitability, but both are essential considerations. Revenue prediction and evaluation cannot proceed in my opinion, however, without a mathematical model of shelter capacity, intensity, activity, location, condition and revenue performance at the parcel or block level of a city’s anatomy. It is a way to begin understanding the performance of an anatomy that must not sprawl to consume its limited source of life. In the words of Benjamin Franklin, this seems to be a self-evident truth, but to some it will merely represent an opinion.
