Leon Krier says that a city should be broken down into urban quarters. He says, “The Quarter must integrate all daily functions of urban life (dwelling, working, leisure) within a territory dimensioned on the basis of the comfort of a walking man; not exceeding 35 hectares (~85 acres) in surface and 15,000 inhabitants” (Leon Krier, Houses, Palaces, Cities, 1984).

“Addison Circle, a high-density new urbanist development in Addison, Texas, continues to be highly successful. Developer Post Properties announced the complete lease up of Phase 2 in April, 2000. Addison Circle now includes 1,070 apartments, 111,000 square feet of retail, 340,000 square feet of office and 234 storage units. Leasing began in Addison in 1997. Designed by RTKL, the 80-acre project will eventually be 3,000 residential units and four million square feet of commercial. The tight streetscape and high density give Addison the feel of a European city neighborhood, in the middle of a sprawling edge city” (“New Urban Update”, New Urban News, July/August 2000).

“Some municipalities, like Dade County, allow higher densities for developers that build the New Urbanism, because the concept is geared to enable a compact mix of uses to work together harmoniously. ‘If you give us three of four units per acre bonus in a high land cost area, that is great incentive,’ Hernandez says” (“Pros and Cons for Builders Attempting New Urbanism”, New Urban News, January/February 1999).

“A study funded by the National Oceanic and Atmospheric Administration (NOAA) for the Charleston Harbor project confirms this, finding that low-density sprawl is almost three times as polluting as compact, higher density development, other factors being equal” (Dana Beach, “How Federal ‘Non-point Source’ Programs Promote Sprawl”, New Urban News, January/February 1999).

“There must be a sufficiently dense concentration of people, for whatever purposes they may be there. This includes dense concentration in the case of people who are there because of residence” (Jane Jacobs, The Death and Life of Great American Cities, 1961).

”Minzer Park in Boca Raton, Florida, is one of the best-known and most successful new urbanist retail developments. The project has a density five times higher than the rest of the city and a mix of large and small retailers, restaurants and entertainment venues” (“New Urbanist Retail Gathers Momentum”, New Urban News, November/December 1999).

“In the conventional development scenario, the 300 acre site is carved into only 38 lots for single family houses. With an estimated average price per unit of $200,000, the total value of the development would be $7.6 million In the new urbanist scenario, however, single family houses are built alongside townhouses, live/work units, and apartments, 168 dwelling units in all. In addition, the new urbanist plan adds a mix of uses with 64,000 square feet of office, retail, and civic building. At build-out, the total estimated dwelling value would be $21.28 million and the value of commercial and civic building $6.45 million, for a total of $17.73 million” (“Higher Density Equals Higher Value”, New Urban News, March/April 2000).

“The hardest city districts to deal with will be residential gray areas that lack infusion of work to build upon, and that also lack high densities of dwellings. Failing or failed city areas are in trouble not so much because of what they have (which can always be regarded as a base to build upon), but because of what they lack” (Jane Jacobs, The Death and Life of Great American Cities, 1961).

“The infrastructure costs per unit in the new urbanist plan also appear to be significantly lower. The new urbanist plan calls for 551 square feet of pavement per dwelling, compared to 2,018 square feet of pavement for the conventional suburban plan” (“Higher Density Equals Higher Value”, New Urban News, March/April 2000).

”Even with higher infrastructure costs per acre with the New Urbanism, more units per acre means equal or lower infrastructure costs per unit. The key to that equation is that the New Urbanism makes higher density look good, according to Michael McAfee, project manager for Avalon Park, a TND in an early stage of construction” (“Controlling the Costs of TND Infrastructure”, New Urban News, July/August 1998).

“Due to narrower lot sizes and more townhomes and apartments, the new urbanist plan featured 71 percent higher density than CSD (6,857 dwelling units compared to 4,005 dwelling units). ‘When measured on a per unit basis,’ the study points out, ‘the alternative plan is 8.8 percent more economical. This is based on a life-cycle cost savings of $10,977 per unit. The per unit New Urbanism savings were as follows: roads ($3,054), stormwater management ($1,499), transit ($1,330), water ($1,099), policing ($1,016), and sanitary sewer ($975)” (“Density Makes New Urbanism Cheaper”, New Urban News, July/August 1998).

“The New Urbanism is seen by many Maryland planners as a way to attractively design higher density growth that they believe is required to achieve smart growth goals. ‘New Urbanism certainly is an important part of smart growth,’ says Young” (“States Take Action to Limit Sprawl”, New Urban News, March/April 1998).
