On today\\u2019s show we are talking about how maturing cities handle growth and development.\\xa0

There are two costs associated with growth. There is the initial cost, and then there is the lifecycle cost.\\xa0

Buildings and neighbourhoods go through cycles of development, stagnation, decline and renewal. Cities therefore go through cycles as well.\\xa0

When a city is growing it costs money to build roads and schools and infrastructure like water treatment and sewage treatment. These costs are initial costs that are often paid for by developers that are responsible for the growth.\\xa0 For the first number of years, that new infrastructure is very low maintenance. It\\u2019s new and pristine and the cost of maintaining it is effectively zero.\\xa0But eventually, those roads will need to be repaved, and the sidewalks repaired. Landscaping will need a refresh.\\xa0

The schools that were new and filled to capacity will eventually be under-utilized as families move out of those mature neighborhoods.\\xa0The cost of maintaining the roads and the schools remains constant over time.

It\\u2019s much cheaper to re-use existing infrastructure through the process of urban renewal instead of letting major regions of the city decay into an urban wasteland.\\xa0

Intensification is the word that best encapsulates the eco-friendly aspect of urban renewal.\\xa0

The problem with infill projects is that they\\u2019re small. They\\u2019re too small for large scale home builders. You can\\u2019t mobilize an entire framing crew to move from one property to the next in an infill setting. There is simply not enough work to make the process efficient.\\xa0

Just like an assembly line is more efficient at making cars than building them one at a time, a residential subdivision is the assembly line equivalent when it comes to home building.\\xa0

But we\\u2019re trading one form of efficiency for another. Efficiency for the builders is coming at the expense of efficiency for the city. The life cycle cost for the cities is actually more important. Intensification in cities is environmentally friendlier than gobbling up more agricultural land and allowing cities to expand outward meanwhile land in the core lies under-utilized.\\xa0
