Density is a central factor in creating the experience of urban intensity, but it is not the element that makes it pleasurable. Density offers access to many choices, but the ease of use is what makes it enjoyable. Many factors may point to a place of interest. Still, numeric measures are written alone to regulate height and mass with the floor area, and open space ratios are without the elements needed. To describe or judge success or failure is established in part by Mami21. Given the change in global conditions, this is a place to watch.
Jobs and population per acre are common measures of density. Simultaneously, design components such as the ratio of building mass to open space only frame the possibility of a quality experience. Places from low- to high-density tie to individual place finding or marketing algorithms that provide a sense of position that reflects a personal value within a community such as Miami.
The images in patchwork nation will illustrate the U.S. in 12 community types by using demographic, political, and socioeconomic data. What is not shown is how a census block group of any major urban center will easily replicate the nation’s image by county. That the nation has these social densities as similarly as a city is encouraging. What the nation is missing is the intensity of the city as an intentionally diverse place.
Density and community land use formulas tend to see a house always being a house or an office complex limited to business. In an intensely used urban environment, these initial functions yield many new, often unexpected uses. Density provides the opportunity for a critical mass of interaction. Still, it works best when combined with an open-ended set of form elements to produce the desire for development intensity that, in turn, leads to a sense of confidence about dynamically changing sets of land uses.
A region with 100 jobs and 200 residents per acre may identify a comparatively dense area and signify a transit-oriented mixed-use center. Using this measure, the development intensity tier includes the number of time intervals that link to other transit-oriented centers. These areas might have lower residential/job densities jobs per acre or higher. Each signifies an edge where the intensity accelerates or declines. The density itself remains significant as an intensifying agent within a traditional street grid, height, and scale ratios. Areas operating without this constraint tend to yield grey zones, lost landscapes, and forgotten trends. Growth without constraint is what kills them. The death is rapid, and it shames the residential community into which it was injected.
Before heading off to the University of Utah, Arthur “Chris” Nelson was in the Urban Affairs and Planning program at Virginia Tech’s Washington-Alexandria Center. His research indicated a doubling of the Greater Washington, D.C. region’s entire built environment could occur by 2030. The concept of exponential growth is intoxicating in mega-regions such as the northeast. Still, the Greenfield development rate is by all accounts unsustainable, and that policy measures to focus (if not force) this energy into the existing built environment require implementation. Without new restraints, most job growth will occur outside of the urban core areas, resulting in nothing more than a vast enlargement of the current inner-city design process over a much larger section of the metropolitan region. Conclusions from this analysis demand a new regime of land use and building controls authored on a regional basis and of necessity across state lines. One mega-region is contained with Florida, whose development concerns turned to a form basis.
The purpose of a “form-based code” is to yield to human creative purposes with a greater trust in performance measures and regulations affecting access to natural light, clean air, lack of noise, and other events or qualities that affect the quality of life. When Miami 21 was passed by the city in October 2009, introducing the “transect” idea may change everything in land use management. It is a boundary line around a land area for ecological measurements. Injecting this idea into land use and development decisions is protective of life and contributes to contextual development events and conversion. Although NYC used the code was involved in the transition of the West Side Highway in Manhattan into a street near waterfront parkland speaks to this purpose. Today it is not exactly the Camps-Elysee, but there are aspirations. This potential is now far greater than that offered by former existence as limited access, elevated super-highway.
The principles of form-based code limit building heights based on the street grids. Yet as a constraint, it recognizes and supports traditional neighborhood resilience. These communities offer a vibrant series of mixed-use centers that accommodate growth and increased urban intensity. With multiple forms of public mass transit, this intensity also contributes to the growth of other mixed-use urban centers or edge cities and employment centers throughout the region.

Link for exploration fun: Flamingo Park, Miami Beach, FL Towers on a barrier beach – what could go wrong or be better? I’m looking to cite a study of falling RE and condo prices.
