Planning issues are often considered to be conflicts between the interests of different groups, such as neighborhood residents versus developers, or motorist versus transit users. But planning concerns the future, so it often consists of a conflict between the interests of our current and future selves.
For example, I have relatives who live in the city of Vancouver, which is developing an Ecodensity Policy that will increase infill development, particularly affordable housing and commercial services along major public transit corridor. It's a controversial policy with lots of opposition from residents who assume that it contradicts their interests. "It will just increase traffic and parking problems," they object. They should think again. They may want affordable housing and better transport options in the future.
For example, one of my relatives who opposes Ecodensity lives in a nice old, relatively inexpensive apartment in a desirable Vancouver neighborhood and drives to work every day. Sometime in the future her landlord will probably raise the rent or redevelop the building, forcing this woman to search of more affordable housing, while increasing urban traffic, rising fuel prices and aging may make driving more difficult. At that time she may benefit a lot from Ecodensity. Even if she moves into an older apartment and continues to drive she will benefit from overall reductions in housing prices and traffic congestion. Vancouver housing will not become really cheap, nor will traffic congestion disappear, but Ecodensity should significantly reduce these problems, making her future self better off. This may even determine whether or not she can continue to live in one of the world's most livable cities.
Imagine what a message from yourself a couple decades in the future might say concerning the type of development policies your community should establish now. If you are lucky and selfish the message might favor restrictions on affordable, infill housing and automobile-oriented transport planning. However, if your future self might be physically disabled or poor, or concerned about physically and economically disadvantaged neighbors, your future self will want lots of affordable housing located in areas with good travel options, and plenty of local services that support healthy and happy lifestyles, such as local parks and inexpensive shops. Wow, we just reinvented Ecodensity!
Planning decisions we make today will affect our quality of life in coming years and decades. Since our future condition is unknowable, it makes sense to create communities that do a really good job of caring for disadvantaged people, because that could be us.
